"Unidentified life form" found off New Zealand coast

<p>Ah, the deep sea, where the mysteries of the ocean lurk in the shadows, waiting to be discovered by intrepid marine scientists armed with nets, trawls and a healthy dose of confusion...</p> <p>Recently, a team of brave souls embarked on a journey off the coast of New Zealand, armed with curiosity and a fervent desire to find Nemo's distant relatives. What they found, however, was not just Nemo's cousins – but a veritable treasure trove of potential new species. Or at least, they think so.</p> <p>In a saga that could rival any aquatic adventure film, the scientists stumbled upon approximately 100 potential new species, including one particularly enigmatic life form that has left them scratching their heads in bewilderment.</p> <p>Initially mistaking it for a sea star – or perhaps a particularly flamboyant sea cucumber – they now suspect it might be a deep-sea coral. Or a cosmic jellyfish. Or a lost prop from a sci-fi movie. The possibilities are as endless as the ocean itself.</p> <p>Dr Michela Mitchell, a taxonomist with a penchant for the dramatic, declared it could be "a whole new group outside of the octocoral." Because why settle for identifying just one species when you can potentially create an entire taxonomic order?</p> <p>Dr Daniel Moore, another member of the expedition and self-proclaimed captain of the confusion ship, confessed, "We can't even describe it to family." One can only imagine the perplexed expressions at family gatherings as they attempt to explain their latest discovery: "Well, it's sort of like a sponge, but not really. And it might have tentacles. Or wings. We're not entirely sure."</p> <p>Their research vessel, the <em>Tangaroa</em>, became a floating laboratory of befuddlement as they collected nearly 1,800 samples from the abyssal depths. Armed with modified sleds and a healthy dose of optimism, they trawled the ocean floor, hoping to snag the elusive creatures that lurked below.</p> <p>"It was true exploration, very exciting," Dr Moore boasted, his enthusiasm undiminished by the fact that they still couldn't <em>definitively</em> identify half of what they'd found.</p> <p>Among their discoveries was a new species of fish, dubbed the "eelpout", which was "instantly recognised as being different to the others." Because, apparently, it had a flair for the dramatic and refused to conform to traditional fish norms.</p> <p>In a surprising revelation, Dr Moore admitted, "Finding new vertebrates is rare." One can only assume that the eelpout, upon hearing this declaration, puffed out its chest (or whatever passes for a chest in fish anatomy) and proclaimed itself the king of the ocean.</p> <p>As the expedition came to a close, the scientists reflected on the vastness of the ocean and the infinitesimal fraction of its inhabitants they had encountered. With only 240,000 species identified out of an estimated 2.2 million, they realised they had barely scratched the surface. Or, in this case, the sea floor.</p> <p>And so, armed with their nets, their sleds, and their unshakeable sense of optimism, the intrepid scientists set sail once more, ready to delve deeper into the mysteries of the ocean and perhaps stumble upon another baffling creature that defies explanation. After all, what's science without a little bit of confusion?</p> <p><em>Image: Ocean-Census | NIWA</em></p>

Marine species are being pushed towards the poles. From dugong to octopuses, here are 8 marine species you might spot in new places

The ocean has absorbed the vast majority of the extra heat trapped by carbon dioxide and other greenhouses gases.

If the water heats up, they have to move, and if they don’t, they might die. So those that can move, are moving. In Australia, at least 200 marine species have <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.15634">shifted distributions</a> since 2003, with 87% heading south.</p> <p>This pattern is happening all around the world, both on land and <a href="https://theconversation.com/thousands-of-photos-captured-by-everyday-australians-reveal-the-secrets-of-our-marine-life-as-oceans-warm-189231">in the ocean</a>. This year, the warmer ocean temperatures during winter mean Australia’s seascapes are likely to be more like summer.

As WA fisheries expert Gary Jackson has said, this current is a warming hotspot, acting like a warm water highway for certain marine species.</p> <p>These fish are highly <a href="https://goodfish.org.au/species/red-emperor/">sought after</a> by fishers.</p> <p><strong>8.

Cats declared an “invasive alien species” in Poland

<p dir="ltr">A scientific institute in Poland has categorised domestic cats as an “invasive alien species”, joining a menagerie of animals on their invasive species list.</p> <p dir="ltr">The Polish Academy of Sciences has deemed the house cat (Felis catus) as an “alien” species as it was domesticated in the Middle East, and “invasive” due to the “negative influence of domestic cats on native biodiversity”, according to a statement.</p> <p dir="ltr">Cats join a long list of animals and plants deemed an “invasive alien species” by the institute, including Japanese knotweed, racoons, clearwing moths and mandarin ducks.</p> <p dir="ltr">The Academy states that cats pose “an unpredictable risk to local wildlife”, citing <a href="https://www.sciencedirect.com/science/article/pii/S2351989418303196?via%3Dihub" target="_blank" rel="noopener">a study</a> that shows cats kill 41.1 million mammals and 8.9 million birds each year, eating an additional 583.4 million mammals and 135.7 birds.</p> <p dir="ltr">Wojciech Solarz, a biologist at the state-run institute, told <a href="https://apnews.com/article/science-poland-wildlife-cats-birds-b942a55135832d085375de73c9cc2e23?user_email=d892765ed707c6b27af3429c2e8ec0607119ec5a15758542d760a9bac7b882a8&amp;utm_source=Sailthru&amp;utm_medium=email&amp;utm_campaign=July27_MorningWire&amp;utm_term=Morning%20Wire%20Subscribers" target="_blank" rel="noopener">AP</a> that the criteria to be declared an alien invasive species “are 100 percent met by the cat”.</p> <p dir="ltr">However, cat owners and lovers have expressed outrage at the decision, arguing it could incite abuse or mistreatment of cats, with concerned commenters declaring it “simply stupid and harmful” on the Academy’s Facebook page.</p> <p dir="ltr">AP has also reported that some media reports have incorrectly given the impression that the Academy was calling for cats to be euthanized.</p> <p dir="ltr">Solarz told the outlet he hadn’t expected such a response, adding that no other entry on their database of invasive and alien species had resulted in such an emotional response.</p> <p dir="ltr">He suggested that the negative feedback may be due to a misunderstanding that the Academy was implying that people harm their cats.</p> <p dir="ltr">In actuality, the Academy has only recommended that cat owners limit the amount of time their pets spend outdoors during bird breeding season.</p> <p><span id="docs-internal-guid-3485969e-7fff-54f6-de1d-11099865d6bb"></span></p> <p dir="ltr"><em>Images: Getty Images</em></p>

Some endangered species can no longer survive in the wild. So should we alter their genes?

<p>Around the world, populations of many beloved species are declining at increasing rates. According to one <a href="https://www.theguardian.com/environment/2020/sep/30/world-plant-species-risk-extinction-fungi-earth">grim projection</a>, as many as 40% of the world’s species may be extinct by 2050. Alarmingly, many of these declines are caused by threats for which few solutions exist.</p> <p>Numerous species now depend on conservation breeding programs for their survival. But these programs typically do not encourage species to adapt and survive in the wild alongside intractable threats such as climate change and disease.</p> <p>This means some species can no longer exist in the wild, which causes major downstream effects on the ecosystem. Consider, for example, how a coral reef would struggle to function without corals.</p> <p>What if there was another way? My colleagues and I have developed an intervention method that aims to give endangered species the genetic features they need to survive in the wild.</p> <p><img src="https://images.theconversation.com/files/411140/original/file-20210714-13-1bf7ccv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="bleached coral with fish" /> <span class="caption">Genetically altering coral may help them survive in a warmer world.</span> <span class="attribution"><span class="source">Rick Stuart-Smith</span></span></p> <h2>Bringing theory into practice</h2> <p>Over generations, natural selection enables species to adapt to threats. But in many instances today, the speed at which threats are developing is outpacing species’ ability to adapt.</p> <p>This problem is especially apparent in wildlife threatened by newly emerging infectious diseases such as chytridiomycosis in amphibians, and in climate-affected species such as corals.</p> <p>The toolkit my colleagues and I developed is called “targeted genetic intervention” or TGI. It works by increasing the occurrence or frequency of genetic features that impact an organism’s fitness in the presence of the threat. We outline the method in a recent <a href="https://www.sciencedirect.com/science/article/abs/pii/S0169534721003384">research paper</a>.</p> <p>The toolkit involves <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/artificial-selection">artificial selection</a> and <a href="https://www.frontiersin.org/articles/10.3389/fbioe.2019.00175/full">synthetic biology</a>. These tools are well established in agriculture and medicine but relatively untested as conservation tools. We explain them in more detail below.</p> <p>Many tools in our TGI toolkit have been discussed in theory in conservation literature in recent decades. But rapid developments in genome sequencing and synthetic biology mean some are now possible in practice.</p> <p>The developments have made it easier to understand the genetic basis of features which enable a species to adapt, and to manipulate them.</p> <p><img src="https://images.theconversation.com/files/442166/original/file-20220124-19-xc82dx.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="frog on wet rock" /> <span class="caption">Some animal species cannot adapt in time to survive threats such as disease.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>What is artificial selection?</h2> <p>Humans have long used artificial (or phenotypic) selection to promote desirable characteristics in animals and plants raised for companionship or food. This genetic alteration has led to organisms, such as domestic dogs and maize, that are dramatically different from their wild progenitors.</p> <p>Traditional artificial selection can lead to outcomes, such as high inbreeding rates, that affect the health and resilience of the organism and are undesirable for conservation. If you’ve ever owned a purebred dog, you might be aware of some of these genetic disorders.</p> <p>And when it comes to conservation, determining which individuals from a species are resistant to, say, a deadly pathogen would involve exposing the animal to the threat – clearly not in the interests of species preservation.</p> <p>Scientists in the livestock industry have developed a new approach to circumvent these problems. Called genomic selection, it combines data from laboratory work (such as a disease trial) with the genetic information of the animals to predict which individuals bear genetic features conducive to adaptation.</p> <p>These individuals are then chosen for breeding. Over subsequent generations, a population’s ability to survive alongside pervasive threats increases.</p> <p>Genomic selection has led to disease-resistant salmon and livestock that produce more milk and better tolerate heat. But it is yet to be tested in conservation.</p> <p><img src="https://images.theconversation.com/files/442161/original/file-20220124-27-11vyq0z.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="cows in green field" /> <span class="caption">Artificial selection has been used to develop traits that humans desire in livestock.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>What is synthetic biology?</h2> <p><a href="https://www.genome.gov/about-genomics/policy-issues/Synthetic-Biology">Synthetic biology</a> is a toolkit for promoting change in organisms. It includes methods such as transgenesis and gene editing, which can be used to introduce lost or novel genes or tweak specific genetic features.</p> <p>Recent synthetic biology tools such as <a href="https://medlineplus.gov/genetics/understanding/genomicresearch/genomeediting/">CRISPR-Cas9</a> have created a buzz in the medical world, and are also starting to gain the <a href="https://portals.iucn.org/library/node/48408">attention</a> of conservation biologists.</p> <p>Such tools can accurately tweak targeted genetic features in an individual organism – making it more able to adapt – while leaving the rest of the genome untouched. The genetic modifications are then passed on to subsequent generations.</p> <p>The method reduces the likelihood of unintended genetic changes that can occur with artificial selection.</p> <p>Synthetic biology methods are currently being trialled for conservation in multiple species around the world. These include the <a href="https://www.esf.edu/chestnut/resistance.htm">chestnut tree</a> and black-footed <a href="https://neo.life/2021/05/cloning-wildlife-and-editing-their-genes-to-protect-them-and-us/">ferrets</a> in the United States, and <a href="https://theconversation.com/gene-editing-is-revealing-how-corals-respond-to-warming-waters-it-could-transform-how-we-manage-our-reefs-143444">corals</a> in Australia.</p> <p>I am working with researchers at the University of Melbourne to develop TGI approaches in Australian frogs.

For example, genetic features that make a species resistant to one disease may make it more susceptible to another.</p> <p>But the rapid rate of species declines means we should trial such potential solutions before it’s too late. The longer species are absent from an ecosystem, the greater the chance of irreversible environmental changes.</p> <p>Any genetic intervention of this type should involve all stakeholders, including Indigenous peoples and local communities. And caution should be taken to ensure species are fit for release and pose no risk to the environment.</p> <p>By bringing the concept of TGI to the attention of the public, government, and other scientists, we hope we will spur discussion and encourage research on its risks and benefits.<!-- Below is The Conversation's page counter tag.

Ancient knowledge is lost when a species disappears. It’s time to let Indigenous people care for their country, their way

<p>Indigenous people across Australia place tremendous cultural and customary value on many species and ecological communities. The very presence of a plant or animal species can trigger an Indigenous person to recall and share knowledge. This is crucial to maintaining culture and managing Country.</p> <p>But as species disappear, ancient knowledge built up over thousands of years also fades away – and fragments of our culture are lost forever.</p> <p>For years, Indigenous groups have pushed for the right to partner with government authorities to “co-manage” culturally significant species and communities. Such recognition of Indigenous rights would require amendments to environment and land management laws.</p> <p>Unfortunately, changes to Australia’s federal environment laws currently underway fall short of what’s needed. To protect Australia’s imperilled species, the law must chart a new course that allows Indigenous groups to manage their Country, their way.</p> <p><a href="https://images.theconversation.com/files/434938/original/file-20211201-25-189bdrg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/434938/original/file-20211201-25-189bdrg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="A woman welcomed to Country" /></a> <span class="caption">Ngurrara Ranger Mary is welcomed to Paruku Country in the Great Sandy Desert.

It includes land and sea held through such means as traditional ownership, native title and land rights organisations. It also includes intangible values such as cultural rights, practice and expression, as well as Indigenous knowledge and traditional management.</p> <p>A range of state and federal programs involve Indigenous participation in land and sea management, offering invaluable protection to the Indigenous estate. These include Indigenous Protected Areas and the successful <a href="https://www.niaa.gov.au/indigenous-affairs/environment/indigenous-ranger-programs">Indigenous Ranger program</a>.</p> <p>And many governments and other groups recognise that species and ecological communities can have significant cultural, spiritual and customary value to Indigenous Australians. But often, no legal mechanism exists to protect these entities.</p> <p>Some species and other entities of significance to Indigenous Australians are listed as threatened under Australia’s federal environment law, known as the Environment Protection and Biodiversity Conservation (EPBC) Act. But authorities are not required to engage Indigenous Australians in the listing, management or recovery of these species.</p> <p>Indigenous Australians have successfully managed this continent’s landscapes and seascapes for tens of thousands of years. Their approach is holistic and integrated – considering the whole cultural landscape with a deep understanding of the interconnected relationships between species and Country.</p> <p>In contrast, management actions under federal environment law focus on the outcomes of the listed species instead of the overall health of Country.</p> <p>All this has left Indigenous groups underfunded and at the mercy of national-level management decisions, as opposed to place-based Indigenous-led action.</p> <p><a href="https://images.theconversation.com/files/434940/original/file-20211201-25-b87h6o.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/434940/original/file-20211201-25-b87h6o.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Men sitting around a map" /></a> <span class="caption">Ngurrara Rangers map potential night parrot habitat.

His <a href="https://epbcactreview.environment.gov.au/resources/final-report">final report</a> in 2020 found the law was failing in many ways.</p> <p>Samuel recommended a suite of reforms. Among other goals, they aimed to “respect and harness the knowledge of Indigenous Australians”. One year on and <a href="https://www.canberratimes.com.au/story/7591429/a-year-on-from-a-landmark-report-nature-and-law-reform-is-floundering/">progress</a> on implementing the 38 recommendations is slow.</p> <p>Among the recommendations were that the EPBC Act adopt a set of legally enforceable “national environmental standards” – clear rules that protect the environment and enable sustainable development. The standards <a href="https://www.theguardian.com/australia-news/2021/jan/28/australia-urged-to-overhaul-environment-laws-and-reverse-decline-of-our-iconic-places">would cover</a> matters such as threatened species, compliance, environmental data and <a href="https://epbcactreview.environment.gov.au/resources/final-report/appendix-b2-indigenous">Indigenous engagement</a> and participation in decision-making.</p> <p>It was both surprising and disappointing that Indigenous knowledge was not embedded across all proposed environmental standards. The omission means Indigenous perspectives will continue to be relegated to a stand-alone standard of “participation”.</p> <p>In particular, the national standard pertaining to threatened species made no reference to Indigenous knowledge or the Indigenous estate. And proposed <a href="http://www.environment.gov.au/system/files/pages/44b768d8-75ad-417d-84cc-dfb0e069e97e/files/national-environmental-standard-mnes-2021-draft.pdf">interim standards</a> completely omit Indigenous engagement, participation and values.</p> <p>Without a mandate to include Indigenous people in threatened species planning and recovery, biodiversity will remain at risk.

Garden birds are struggling: four ways to help

<p>More than a quarter of Britain’s birds are now on the RSPB’s <a rel="noopener" href="https://www.rspb.org.uk/birds-and-wildlife/wildlife-guides/uk-conservation-status-explained/" target="_blank">red list</a>, meaning that their numbers are in severe decline.</p> <p>Some of the recent additions to the red list are thought of as common garden birds, such as the greenfinch. Others, such as the swift and house martin, only spend spring and summer visiting the UK before migrating to warmer climes. But the environment they encounter in the UK, as well as along their migration routes, affects their survival significantly.</p> <p>Many of the species that we feed in our gardens and on balconies are under threat. Here are four ways to help them.</p> <p><strong>1. Clean your bird feeders and bird baths</strong></p> <p>In the wild, with a few exceptions such as starlings, birds don’t come into close contact with each other much. This lack of contact makes it harder for diseases to spread.</p> <p>Bird feeders change this dynamic. The presence of a bird feeder means that many individual birds from many different species feed in the same area. This leads to the <a rel="noopener" href="https://www.bto.org/community/news/201803-feed-birds-scientists-highlight-risks-disease-garden-bird-feeders" target="_blank">spread of disease</a>, because birds often poo where they eat, leaving pathogens to infect the next visitor.</p> <p><img src="https://images.theconversation.com/files/438076/original/file-20211216-23-13tbwiw.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Two birds on a house shaped feeder" /> <em><span class="caption">Greenfinches on a bird feeder.</span> <span class="attribution"><a rel="noopener" href="https://www.shutterstock.com/image-photo/greenfinches-perching-on-bird-feeder-spring-1667803654" target="_blank" class="source">Chamois huntress/Shutterstock</a></span></em></p> <p>The greenfinch, a once common garden bird now added to the red list, has suffered because of this. The disease <a rel="noopener" href="https://www.bto.org/our-science/projects/gbw/gardens-wildlife/garden-birds/disease/trichomonosis" target="_blank">trichomonosis</a>, which used to just infect pigeons and doves, has spread to greenfinches with deadly consequences. Regular cleaning of your garden bird feeders and bird baths can reduce this risk.</p> <p><strong>2. Install bird nesting boxes</strong></p> <p>Many people help birds by putting up nest boxes in their gardens. But these boxes are mostly made for robins and tits who nest in open boxes, or ones with small holes. These nest boxes mimic the crevices and holes that would be available in mature trees.</p> <p>Swifts and house martins are new entrants to the red list, and both of these will readily use man-made nesting places if we provide them – with a few modifications for their needs.</p> <p>House martins will nest in a pre-made or home-made <a rel="noopener" href="https://www.rspb.org.uk/birds-and-wildlife/advice/how-you-can-help-birds/nestboxes/how-to-attract-house-martins/" target="_blank">nest cup</a> which mimics the mud nests house martins make for themselves.</p> <p>Swifts will <a rel="noopener" href="http://www.saveourswifts.co.uk/attractswifts.htm" target="_blank">nest in boxes</a>, but they take a bit more work to attract. The best way to do this is to play their screeching call from a speaker placed close to the nest box, to get them to investigate and hopefully nest.</p> <p>You can make nest boxes attractive to these species by installing them in the eaves of your home, as they need them to be up high so they can take flight from them easily.</p> <p><strong>3. Add some insect-friendly plants</strong></p> <p>Many of the species entering the red list, such as the house martin and house sparrow, feed on insects. Insects numbers have <a rel="noopener" href="https://www.nhm.ac.uk/discover/news/2019/february/the-world-s-insect-populations-are-plummeting-everywhere-we-look.html" target="_blank">declined rapidly</a>, so it is no surprise that these avian predators are finding it hard to feed themselves and their chicks.</p> <p>You may love a neat and tidy garden or balcony, but set aside an area to be a bit messier and weedier to attract insects. Adding <a rel="noopener" href="https://www.rhs.org.uk/science/conservation-biodiversity/wildlife/plants-for-pollinators" target="_blank">pollinator-friendly plants</a>, such as lavender, foxglove and sedum, could really boost insect numbers – natural bird food – in your garden.</p> <p><strong>4. Reduce dangers to birds</strong></p> <p><a rel="noopener" href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0049369" target="_blank">Pet cats are predators</a> and can target species like house sparrows, which remain on the red list. Even the presence of cats could be enough to <a rel="noopener" href="https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2664.12025" target="_blank">scare birds</a>, reducing the number of young they may be able to have. This may have a more damaging impact on bird populations than the number of birds killed by cats.</p> <p><img src="https://images.theconversation.com/files/438077/original/file-20211216-17-10dzdgj.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Cat stalking along fence under roses" /> <em><span class="caption">Cats are predators and their presence affects bird populations.</span> <span class="attribution"><a rel="noopener" href="https://www.shutterstock.com/image-photo/cat-burglar-front-roses-on-prowl-1503499694" target="_blank" class="source">Lilly P. Green/Shutterstock</a></span></em></p> <p>If you own a cat, there are ways for you to reduce its effect on bird numbers. A collar with a bell is an effective way to warn birds and other animals about a cat’s presence.</p> <p>In addition, you could consider restricting when cats are allowed outside to just the daytime, as birds can be more vulnerable in the very early morning when they wake and start to look for food. Alternatively, you could keep cats inside entirely. It is very common in Australia and the US for cats to remain indoors.</p> <p>These changes may seem small and your garden or outdoor space may not be big, but gardens in the UK <a rel="noopener" href="https://www.wildlifetrusts.org/habitats/towns-and-gardens" target="_blank">cover more area</a> that all of our nature reserves put together. Encouraging wildlife in these garden habitats can make a big difference.<!-- Below is The Conversation's page counter tag.

Hibbert’s flowers and Hitler’s beetle – what do we do when species are named after history’s monsters?

<p>“What’s in a name?”, <a href="https://www.bartleby.com/70/3822.html">asked Juliet of Romeo</a>. “That which we call a rose by any other name would smell as sweet.”</p> <p>But, as with the Montagues and Capulets, names mean a lot, and can cause a great deal of heartache.</p> <p>My colleagues and I are <a href="https://theconversation.com/its-not-the-science-of-tax-and-five-other-things-you-should-know-about-taxonomy-78926">taxonomists</a>, which means we name living things. While we’ve never named a rose, we do discover and name new Australian species of plants and animals – and there are a lot of them!</p> <p>For each new species we discover, we create and publish a Latin scientific name, following a set of international rules and conventions. The name has two parts: the first part is the genus name (such as <em>Eucalyptus</em>), which describes the group of species to which the new species belongs, and the second part is a species name (such as <em>globulus</em>, thereby making the name <em>Eucalyptus globulus</em>) particular to the new species itself. New species are either added to an existing genus, or occasionally, if they’re sufficiently novel, are given their own new genus.</p> <p>Some scientific names are widely known – arguably none more so than our own, <em>Homo sapiens</em>. And gardeners or nature enthusiasts will be familiar with genus names such as <em>Acacia</em>, <em>Callistemon</em> or <em>Banksia</em>.</p> <p>This all sounds pretty uncontroversial. But as with Shakespeare’s star-crossed lovers, history and tradition sometimes present problems.</p> <h2>What’s in a name?</h2> <p>Take the genus <em><a href="http://www.flora.sa.gov.au/cgi-bin/speciesfacts_display.cgi?form=speciesfacts&amp;name=Hibbertia">Hibbertia</a></em>, the Australian guineaflowers. This is one of the largest genera of plants in Australia, and the one we study.</p> <p>There are many new and yet-unnamed species of <em>Hibbertia</em>, which means new species names are regularly added to this genus.</p> <p>Many scientific names are derived from a feature of the species or genus being named, such as <em>Eucalyptus</em>, from the Greek for “well-covered” (a reference to the operculum or bud-cap that covers unopened eucalypt flowers).</p> <p>Others <a href="https://theconversation.com/its-funny-to-name-species-after-celebrities-but-theres-a-serious-side-too-95513">honour significant people</a>, either living or dead. <em>Hibbertia</em> is named after a wealthy 19th-century English patron of botany, <a href="https://en.wikipedia.org/wiki/George_Hibbert">George Hibbert</a>.</p> <p><img src="https://images.theconversation.com/files/437440/original/file-20211214-15-1u4xyy3.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt="George Hibbert by Thomas Lawrence" /> <span class="caption">George Hibbert: big fan of flowers and slavery.</span> <span class="attribution"><a href="https://commons.wikimedia.org/wiki/File:George_Hibbert_by_Thomas_Lawrence,_1811.JPG" class="source">Thomas Lawrence/Stephen C. Dickson/Wikimedia Commons</a>, <a href="http://creativecommons.org/licenses/by-sa/4.0/" class="license">CC BY-SA</a></span></p> <p>And here’s where things stop being straightforward, because Hibbert’s wealth came almost entirely from the transatlantic slave trade. He profited from taking slaves from Africa to the New World, selling some and using others on his family’s extensive plantations, then transporting slave-produced sugar and cotton back to England.</p> <p>Hibbert was also a prominent member of the British parliament and a <a href="https://www.ucl.ac.uk/lbs/person/view/16791">staunch opponent of abolition</a>. He and his ilk argued that slavery was economically necessary for England, and even that slaves were better off on the plantations than in their homelands.</p> <p>Even at the time, his views were considered abhorrent by many critics. But despite this, he was handsomely recompensed for his “losses” when Britain finally abolished slavery in 1807.</p> <p>So, should Hibbert be honoured with the name of a genus of plants, to which new species are still being added today – effectively meaning he is honoured afresh with each new publication?</p> <p>We don’t believe so. Just like statues, buildings, and <a href="https://theconversation.com/was-first-governor-james-stirling-had-links-to-slavery-as-well-as-directing-a-massacre-should-he-be-honoured-162078">street or suburb names</a>, we think a reckoning is due for scientific species names that honour people who held views or acted in ways that are deeply dishonourable, highly problematic or truly egregious by modern standards.</p> <p><img src="https://images.theconversation.com/files/437442/original/file-20211214-13-1yaho8u.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt="Anophthalmus hitleri" /> <span class="caption">This beetle doesn’t deserve to be named after the most reviled figure of the 20th century.</span> <span class="attribution"><a href="https://commons.wikimedia.org/wiki/File:Anophthalmus_hitleri_HabitusDors.jpg" class="source">Michael Munich/Wikimedia Commons</a>, <a href="http://creativecommons.org/licenses/by-sa/4.0/" class="license">CC BY-SA</a></span></p> <p>Just as Western Australia’s King Leopold Range <a href="https://www.abc.net.au/news/2020-07-03/wa-king-leopold-ranges-renamed-wunaamin-miliwundi-ranges/12416254">was recently renamed</a> to remove the link to the atrocious <a href="https://en.wikipedia.org/wiki/Leopold_II_of_Belgium">Leopold II of Belgium</a>, we would like <em>Hibbertia</em> to bear a more appropriate and less troubling name.</p> <p>The same goes for the Great Barrier Reef coral <em><a href="http://www.edgeofexistence.org/species/elegance-coral/">Catalaphyllia jardinei</a></em>, named after Frank Jardine, a brutal dispossessor of Aboriginal people in North Queensland. And, perhaps most astoundingly, the rare Slovenian cave beetle <em><a href="https://www.inaturalist.org/taxa/773804">Anophthalmus hitleri</a></em>, which was named in 1933 in honour of Adolf Hitler.</p> <p>This name is unfortunate for several reasons: despite being a small, somewhat nondescript, blind beetle, in recent years it has been reportedly <a href="https://www.independent.co.uk/news/world/europe/fans-exterminate-hitler-beetle-6232054.html">pushed to the brink of extinction</a> by Nazi memorabilia enthusiasts. Specimens are even being stolen from museum collections for sale into this lucrative market.</p> <h2>Aye, there’s the rub</h2> <p>Unfortunately, the official rules don’t allow us to rename <em>Hibbertia</em> or any other species that has a troubling or inappropriate name.</p> <p>To solve this, we propose a change to the international rules for naming species. Our <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/tax.12620">proposal</a>, if adopted, would establish an international expert committee to decide what do about scientific names that honour inappropriate people or are based on culturally offensive words.</p> <p>An example of the latter is the <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/tax.12622">many names of plants</a> based on the Latin <em>caffra</em>, the origin of which is a word so offensive to Black Africans that its use is <a href="https://www.cfr.org/blog/k-word-south-africa-and-proposed-new-penalties-against-hate-speech">banned in South Africa</a>.</p> <p>Some may argue the scholarly naming of species should remain aloof from social change, and that Hibbert’s views on slavery are irrelevant to the classification of Australian flowers. We counter that, just like <a href="https://en.wikipedia.org/wiki/Statue_of_Edward_Colston">toppling statues in Bristol Harbour</a> or <a href="https://www.theguardian.com/uk-news/2021/mar/18/goodbye-cecil-rhodes-house-renamed-to-lose-link-to-british-empire-builder-in-africa">removing Cecil Rhodes’ name from public buildings</a>, renaming things is important and necessary if we are to right history’s wrongs.</p> <p>We believe that science, including taxonomy, must be socially responsible and responsive. Science is embedded in culture rather than housed in ivory towers, and scientists should work for the common good rather than blindly follow tradition. Deeply problematic names pervade science just as they pervade our streets, cities and landscapes.</p> <p><em>Hibbertia</em> may be just a name, but we believe a different name for this lovely genus of Australian flowers would smell much sweeter.</p> <p><em>This article was co-authored by Tim Hammer, a postdoctoral research fellow at the State Herbarium of South Australia.</em><!-- Below is The Conversation's page counter tag.

The real reason to worry about sharks in Australian waters this summer: 1 in 8 are endangered

<p>If you’re heading to the beach this summer, the thought of sharks might cross your mind. I don’t mean wondering whether a shark will take you for dinner (that’s very, very unlikely) but rather, how these remarkable creatures are faring in the marine ecosystem.</p> <p>I recently led the first complete assessment of all species of sharks, rays and ghost sharks in Australian waters. My team and I found while most species are secure, about 12%, or 39 species, are threatened with extinction.</p> <p>No country has a higher diversity of sharks than Australia. That means we have a special responsibility to protect them from threats such as fishing and damage to their marine habitat.</p> <p>To prevent shark extinctions on our watch, Australia must invest far more heavily to close vast knowledge gaps and ensure threatened species are protected and recovered.</p> <p><img src="https://images.theconversation.com/files/425737/original/file-20211011-25-16shqs7.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="a stingray" /> <span class="caption">The research examined all species of sharks, rays and ghost sharks found in Australian waters, including the bluespotted fantail ray, pictured.</span> <span class="attribution"><span class="source">Simon Pierce</span></span></p> <h2>Ancient ocean dwellers</h2> <p>Sharks are an ancient lineage of fishes that have roamed the oceans for around <a href="https://www.nhm.ac.uk/discover/shark-evolution-a-450-million-year-timeline.html">450 million years</a>. They occupy tropical, temperate and polar marine waters, while a small number have adapted to live in freshwater.</p> <p>Sharks and their relatives, rays and ghost sharks, are known as cartilaginous fishes. Some 328 of the world’s cartilaginous fishes – comprising one-quarter of the world’s total – occur in Australian waters, including the sub-Antarctic and Antarctic waters. Of these, 138 are found nowhere else on Earth.</p> <p>Globally, sharks face a dire conservation crisis. About <a href="https://www.iucnredlist.org/">32% of species</a> are threatened with extinction and less than half are assessed as “Least Concern” (not at risk of extinction).</p> <p>The main threats around the world are overfishing combined with <a href="https://www.cms.int/en/publication/sharks-ahead-realizing-potential-convention-migratory-species-conserve-elasmobranchs-0">inadequate management</a> such as a lack of fishing regulations, weak protections for threatened species and poor implementation of international agreements.</p> <p>Australia’s relatively better position is a <a href="https://doi.org/10.1093/icesjms/fsx113">result</a> of a long history of ocean policy and fisheries management.

They consist of:</p> <ul> <li>greeneye spurdog</li> <li>eastern angelshark</li> <li>whitefin swellshark</li> <li>narrow sawfish</li> <li>Australian longnose skate.</li> </ul> <p>However, this still leaves a group of under-studied threatened species at risk of slipping through the cracks, because not enough data exists to support official listing nominations. We identified 12 species facing this predicament.</p> <p>For example, we assessed three species of small rays from southeast Australia, known as <a href="https://fishesofaustralia.net.au/home/family/334">stingarees</a>, as vulnerable to extinction due to commercial fishing. The species’ decline has been recorded since the <a href="https://www.publish.csiro.au/mf/MF99174">late 1990s</a>.

Hibbert’s flowers and Hitler’s beetle – what do we do when species are named after history’s monsters?

<p>“What’s in a name?”, <a rel="noopener" href="https://www.bartleby.com/70/3822.html" target="_blank">asked Juliet of Romeo</a>. “That which we call a rose by any other name would smell as sweet.”</p> <p>But, as with the Montagues and Capulets, names mean a lot, and can cause a great deal of heartache.</p> <p>My colleagues and I are <a rel="noopener" href="https://theconversation.com/its-not-the-science-of-tax-and-five-other-things-you-should-know-about-taxonomy-78926" target="_blank">taxonomists</a>, which means we name living things. While we’ve never named a rose, we do discover and name new Australian species of plants and animals – and there are a lot of them!</p> <p>For each new species we discover, we create and publish a Latin scientific name, following a set of international rules and conventions. The name has two parts: the first part is the genus name (such as <em>Eucalyptus</em>), which describes the group of species to which the new species belongs, and the second part is a species name (such as <em>globulus</em>, thereby making the name <em>Eucalyptus globulus</em>) particular to the new species itself. New species are either added to an existing genus, or occasionally, if they’re sufficiently novel, are given their own new genus.</p> <p>Some scientific names are widely known – arguably none more so than our own, <em>Homo sapiens</em>. And gardeners or nature enthusiasts will be familiar with genus names such as <em>Acacia</em>, <em>Callistemon</em> or <em>Banksia</em>.</p> <p>This all sounds pretty uncontroversial. But as with Shakespeare’s star-crossed lovers, history and tradition sometimes present problems.</p> <p><strong>What’s in a name?</strong></p> <p>Take the genus <em><a rel="noopener" href="http://www.flora.sa.gov.au/cgi-bin/speciesfacts_display.cgi?form=speciesfacts&amp;name=Hibbertia" target="_blank">Hibbertia</a></em>, the Australian guineaflowers. This is one of the largest genera of plants in Australia, and the one we study.</p> <p>There are many new and yet-unnamed species of <em>Hibbertia</em>, which means new species names are regularly added to this genus.</p> <p>Many scientific names are derived from a feature of the species or genus being named, such as <em>Eucalyptus</em>, from the Greek for “well-covered” (a reference to the operculum or bud-cap that covers unopened eucalypt flowers).</p> <p>Others <a rel="noopener" href="https://theconversation.com/its-funny-to-name-species-after-celebrities-but-theres-a-serious-side-too-95513" target="_blank">honour significant people</a>, either living or dead. <em>Hibbertia</em> is named after a wealthy 19th-century English patron of botany, <a rel="noopener" href="https://en.wikipedia.org/wiki/George_Hibbert" target="_blank">George Hibbert</a>.</p> <p><img src="https://images.theconversation.com/files/437440/original/file-20211214-15-1u4xyy3.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt="George Hibbert by Thomas Lawrence" /></p> <p><em><span class="caption">George Hibbert: big fan of flowers and slavery.</span> <span class="attribution"><a rel="noopener" href="https://commons.wikimedia.org/wiki/File:George_Hibbert_by_Thomas_Lawrence,_1811.JPG" target="_blank" class="source">Thomas Lawrence/Stephen C. Dickson/Wikimedia Commons</a>, <a rel="noopener" href="http://creativecommons.org/licenses/by-sa/4.0/" target="_blank" class="license">CC BY-SA</a></span></em></p> <p>And here’s where things stop being straightforward, because Hibbert’s wealth came almost entirely from the transatlantic slave trade. He profited from taking slaves from Africa to the New World, selling some and using others on his family’s extensive plantations, then transporting slave-produced sugar and cotton back to England.</p> <p>Hibbert was also a prominent member of the British parliament and a <a rel="noopener" href="https://www.ucl.ac.uk/lbs/person/view/16791" target="_blank">staunch opponent of abolition</a>. He and his ilk argued that slavery was economically necessary for England, and even that slaves were better off on the plantations than in their homelands.</p> <p>Even at the time, his views were considered abhorrent by many critics. But despite this, he was handsomely recompensed for his “losses” when Britain finally abolished slavery in 1807.</p> <p>So, should Hibbert be honoured with the name of a genus of plants, to which new species are still being added today – effectively meaning he is honoured afresh with each new publication?</p> <p>We don’t believe so. Just like statues, buildings, and <a rel="noopener" href="https://theconversation.com/was-first-governor-james-stirling-had-links-to-slavery-as-well-as-directing-a-massacre-should-he-be-honoured-162078" target="_blank">street or suburb names</a>, we think a reckoning is due for scientific species names that honour people who held views or acted in ways that are deeply dishonourable, highly problematic or truly egregious by modern standards.</p> <p><img src="https://images.theconversation.com/files/437442/original/file-20211214-13-1yaho8u.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt="Anophthalmus hitleri" /></p> <p><em><span class="caption">This beetle doesn’t deserve to be named after the most reviled figure of the 20th century.</span> <span class="attribution"><a rel="noopener" href="https://commons.wikimedia.org/wiki/File:Anophthalmus_hitleri_HabitusDors.jpg" target="_blank" class="source">Michael Munich/Wikimedia Commons</a>, <a rel="noopener" href="http://creativecommons.org/licenses/by-sa/4.0/" target="_blank" class="license">CC BY-SA</a></span></em></p> <p>Just as Western Australia’s King Leopold Range <a rel="noopener" href="https://www.abc.net.au/news/2020-07-03/wa-king-leopold-ranges-renamed-wunaamin-miliwundi-ranges/12416254" target="_blank">was recently renamed</a> to remove the link to the atrocious <a rel="noopener" href="https://en.wikipedia.org/wiki/Leopold_II_of_Belgium" target="_blank">Leopold II of Belgium</a>, we would like <em>Hibbertia</em> to bear a more appropriate and less troubling name.</p> <p>The same goes for the Great Barrier Reef coral <em><a rel="noopener" href="http://www.edgeofexistence.org/species/elegance-coral/" target="_blank">Catalaphyllia jardinei</a></em>, named after Frank Jardine, a brutal dispossessor of Aboriginal people in North Queensland. And, perhaps most astoundingly, the rare Slovenian cave beetle <em><a rel="noopener" href="https://www.inaturalist.org/taxa/773804" target="_blank">Anophthalmus hitleri</a></em>, which was named in 1933 in honour of Adolf Hitler.</p> <p>This name is unfortunate for several reasons: despite being a small, somewhat nondescript, blind beetle, in recent years it has been reportedly <a rel="noopener" href="https://www.independent.co.uk/news/world/europe/fans-exterminate-hitler-beetle-6232054.html" target="_blank">pushed to the brink of extinction</a> by Nazi memorabilia enthusiasts. Specimens are even being stolen from museum collections for sale into this lucrative market.</p> <p><strong>Aye, there’s the rub</strong></p> <p>Unfortunately, the official rules don’t allow us to rename <em>Hibbertia</em> or any other species that has a troubling or inappropriate name.</p> <p>To solve this, we propose a change to the international rules for naming species. Our <a rel="noopener" href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/tax.12620" target="_blank">proposal</a>, if adopted, would establish an international expert committee to decide what do about scientific names that honour inappropriate people or are based on culturally offensive words.</p> <p>An example of the latter is the <a rel="noopener" href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/tax.12622" target="_blank">many names of plants</a> based on the Latin <em>caffra</em>, the origin of which is a word so offensive to Black Africans that its use is <a rel="noopener" href="https://www.cfr.org/blog/k-word-south-africa-and-proposed-new-penalties-against-hate-speech" target="_blank">banned in South Africa</a>.</p> <p>Some may argue the scholarly naming of species should remain aloof from social change, and that Hibbert’s views on slavery are irrelevant to the classification of Australian flowers. We counter that, just like <a rel="noopener" href="https://en.wikipedia.org/wiki/Statue_of_Edward_Colston" target="_blank">toppling statues in Bristol Harbour</a> or <a rel="noopener" href="https://www.theguardian.com/uk-news/2021/mar/18/goodbye-cecil-rhodes-house-renamed-to-lose-link-to-british-empire-builder-in-africa" target="_blank">removing Cecil Rhodes’ name from public buildings</a>, renaming things is important and necessary if we are to right history’s wrongs.</p> <p>We believe that science, including taxonomy, must be socially responsible and responsive. Science is embedded in culture rather than housed in ivory towers, and scientists should work for the common good rather than blindly follow tradition. Deeply problematic names pervade science just as they pervade our streets, cities and landscapes.</p> <p><em>Hibbertia</em> may be just a name, but we believe a different name for this lovely genus of Australian flowers would smell much sweeter.</p> <p><em>This article was co-authored by Tim Hammer, a postdoctoral research fellow at the State Herbarium of South Australia.</em><!-- Below is The Conversation's page counter tag.

Why it’s time to reconsider the ecological contribution of introduced species – even in New Zealand

<p>The loss of biodiversity is one of the most catastrophic developments of our time. The impacts will possibly <a href="https://www.nature.com/articles/461472a">outpace those of global warming</a>.</p> <p><img src="https://images.theconversation.com/files/433029/original/file-20211122-15-tb7265.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt="A fantail" /></p> <p><span class="caption">New Zealand’s pīwakawaka: conservation often focuses on saving native species.</span> <span class="attribution"><span class="source">Shutterstock/Imogen Warren</span></span></p> <p>Growing evidence that humans have triggered a <a href="https://www.pnas.org/content/117/24/13596">sixth global mass extinction</a> means the protection of remaining species is a <a href="https://sdgs.un.org/goals">priority beyond dispute</a> to secure ecological services such carbon cycling, clean water and air, and healthy oceans.</p> <p>The key drivers of species loss are climate change, habitat degradation, <a href="https://www.nature.com/articles/nature11148?report=reader">pollution</a>, and <a href="https://link.springer.com/article/10.1007/s10531-018-1595-x">exotic species that become invasive</a>. This has led conservation ecologists to follow the simple rule of “protect natives, fight exotics”.</p> <p>If we had an unlimited budget, I would hardly challenge this view. But in a world where natural ecosystems face many other global changes apart from species loss, I argue we should reconsider the <a href="https://www.frontiersin.org/articles/10.3389/fpls.2021.758413/full">ecological role exotic species play</a>.</p> <h2>Ecosystem function over species mix</h2> <p>One could argue ecosystems are inherently so complex that we can never appreciate the exact contribution of an individual species, and therefore native species need to be protected at all cost.</p> <p>But this argument can be turned around. In many cases, exotic species are not detrimental to the resident species communities. It is not until an exotic species becomes invasive that <a href="https://rewilding.org/wp-content/uploads/2012/04/IUCN-GISP.pdf">substantial harm happens</a>.</p> <p>The deliberate spread of species has been an integral part of human evolution for thousands of years. Many economically important plant species are exotics in most places, but they make it possible to feed our growing population.</p> <p><img src="https://images.theconversation.com/files/433030/original/file-20211122-25-khff1x.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt="New world cacti and succulents in Greece." /></p> <p><span class="caption">New worlld cacti and succulents have become part of the Mediterranean landscape.</span> <span class="attribution"><span class="source">Shutterstock/Anna Holyph</span></span></p> <p>In a physically highly connected world, unintentional relocation of both terrestrial and marine species has now also become unavoidable.</p> <p>In some cases, introduced species can even complement native ecosystems. New world succulents are now very much part of the Mediterranean landscape, without <a href="https://www.presentica.com/doc/11177197/the-role-of-new-world-biodiversity-in-the-transformation-of-document">harming the local flora</a>.</p> <p>Sometimes, introduced species perform ecological functions similar to those that are (or were) performed by natives. For instance, European gorse stabilises coastal slopes in New Zealand, providing a <a href="https://pubmed.ncbi.nlm.nih.gov/19644109">nursery for local plants</a>.</p> <p><img src="https://images.theconversation.com/files/433003/original/file-20211121-27-ccesaa.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Gorse covering a hill in New Zealand." /> <span class="caption">Gorse can act as a nursery plant for New Zealand’s native plant species.</span> <span class="attribution"><span class="source">Shutterstock/Filip Fuxa</span></span></p> <p>In one particularly spectacular case, extinct tortoises were intentionally replaced with an exotic species through “assisted colonisation”. It seems to have <a href="https://pubmed.ncbi.nlm.nih.gov/23773124/">worked</a>.</p> <p>However, earlier and much less scientifically informed attempts of assisted colonisation, such as the deliberate introduction of cane toads in Australia’s tropical north-east, <a href="https://zslpublications.onlinelibrary.wiley.com/doi/abs/10.1111/j.1469-1795.2009.00319.x">went terribly wrong</a>.</p> <h2>The bias of human perception</h2> <p>There are many ecosystem services humanity depends on: clean water, carbon cycling, removal of pollutants and excessive nutrient loads, mitigation of global warming through land-based and marine carbon sequestration, erosion prevention, just to name a few.</p> <p>The preservation of native species is one way of ensuring those services for future generations. An approach focused on ecological function weighs the cost of protecting natives and combating exotics against the role of new species assemblages shaped by human interference.</p> <p>At approximately equal cost, should the addition of a breeding pair of a rare bird be prioritised over the reforestation of several hectares of land? Such decisions are often difficult and must be based on the available science.</p> <p>Clearly, there may be other reasons — cultural or aesthetic values for example — to protect native species, beyond the provisioning of ecosystem services. But people seem biased by what they are used to.</p> <p>For example, Switzerland provides <a href="https://www.bbc.com/news/world-europe-42731932">generous subsidies</a> to farmers for maintaining picturesque alpine meadows, even though the native vegetation before human intervention was a much less biologically diverse alpine forest.</p> <p>In Central Europe, the recently introduced Tree of Heaven (<em>Ailanthus altissima</em>) triggered substantial efforts to eradicate it, while the European chestnut (<em>Castanea sativa</em>), introduced by the Greeks and Romans some 2000 years ago, is highly valued and enjoys <a href="https://link.springer.com/article/10.1007/s00334-004-0038-7">protection and even reforestation programmes</a>.</p> <p>The above examples illustrate why we may need a more sober approach centred on ecological function to effectively protect our remaining natural treasures and the ecosystem services they provide.</p> <p>The <a href="https://www.frontiersin.org/articles/10.3389/fevo.2021.711556/abstract">milestones in the evolution of life</a> did not depend on individual species or species assemblages, but on the emergence of new functional traits such as photosynthesis, predation or flight. Similarly, humankind ultimately relies on functioning ecosystems, regardless of which species provide them.<!-- Below is The Conversation's page counter tag.

With commercial galleries an endangered species, are art fairs a necessary evil?

<p>Although record numbers of people are flocking to exhibitions in the major public art galleries, foot traffic into commercial art galleries is dwindling at an alarming rate. Embarrassed gallery directors of well-established and well-known commercial art galleries will quietly confess that frequently they scarcely get more than a dozen visitors a day. Outside the flurry of activity on the day of the opening, very little happens for the duration of the show.</p> <p>This is not a peculiarity of the Australian art scene, I have heard similar accounts in London, Manhattan and Paris. The art public has largely ceased visiting commercial art galleries as a regular social activity and art collectors are frequently buying over the internet or through art fairs. In fact, many galleries admit that most of their sales occur via their websites, through commissions or at art fairs, with a shrinking proportion from exhibitions or their stockroom by actual walk-in customers.</p> <p>The commercial art galleries have become an endangered species and their numbers are shrinking before our eyes. Leaving aside China and its urban arts precincts, such as <a href="http://www.798district.com/">798 Art Zone in Beijing</a>, again this is a trend that can be noted in much of Europe, America and Australasia.</p> <p>At the same time, the art market is relatively buoyant, albeit somewhat differently configured from the traditional one. The art auction market in many quarters is thriving and, as persistent rumours have it, not infrequently auction houses leave their role as purely a secondary market and increasingly source work directly from artists’ studios. This seeps into their lavish catalogues.</p> <p>The other booming part of the art trade is the art fairs. Here I will pause on a case study of the <a href="http://www.artfair.co.nz/">Auckland Art Fair 2019</a>. Started by a charitable trust about a dozen years ago and run as a biennial, in 2016 the fair, with new sponsorship and a new management team of Stephanie Post and Hayley White, was reorientated. As of 2018, it has become an annual art fair with a focus on the Pacific Rim region. It remains the only major art fair in New Zealand.</p> <p>Situated in The Cloud, a scenic setting on Queens Wharf in central Auckland, this location also limits its size to create an intimate, friendly, human-scale fair, unlike the vast expanses of the <a href="http://www.expochicago.com/">Chicago Art Fair</a> or even <a href="http://www.sydneycontemporary.com.au/">Sydney Contemporary</a> in the Carriageworks.</p> <p>The nuts and bolts of the Auckland Art Fair is that galleries from the Pacific Rim region can apply to exhibit and a curatorial committee of four curators, two from public galleries and two from commercial ones, select about 40 galleries for participation. The event, which is held over five days, attracts about 10,000 visitors and generates between $6-7 million in art sales.</p> <p>The fair costs about $1 million to stage with 90% of this sum raised from sponsorship, ticket sales and gallery fees and the rest a grant from Auckland Tourism, Events and Economic Development. The public pays an admission fee of between $25-30, depending on when they book.</p> <p>Art fairs are popular with local governments as they invariably attract people and businesses into the city. In Auckland Art Fair 2019, held in the first week in May, there were 41 galleries participating, almost 30 from various parts of NZ, the rest from Sydney, Melbourne, Hobart, Shanghai, Jakarta, Rarotonga (Cook Islands) and Santiago.</p> <p>According to Stephanie Post, a major purpose of the fair is to build a new art audience and, by extension, a new generation of art collectors. The fair is designed to fill the gap between the primary and secondary art markets. For this reason, there is a whole series of “projects” that generally promote new art, frequently by emerging artists, many currently without representation by a commercial art gallery. In 2019 there were ten of these non-commercial projects at the fair.</p> <p>These projects, for the past three art fairs, have been curated by Francis McWhannell, who now plans to step aside to be replaced by a new set of curatorial eyes. There are also various lectures, talks, panel discussions and related exhibitions. This year, most notably, there is “China Import Direct”, a curated cross-section of digital and video art from across China with some stunning and quite edgy material by Yuan Keru, Wang Newone and Lu Yang, amongst others.</p> <h2>A mixed bag</h2> <p>Predictably, art at the Auckland Art Fair 2019 is a mixed bag, but the stronger works do outnumber those that are best passed over in silence. In terms of sales, within the first couple of hours quite a number of the big-ticket items were sold, such as work by the Australians Patricia Piccinini and Dale Frank.</p> <p>Looking around this year’s fair, some of the highlights included Seraphine Pick at Michael Lett; Robert Ellis at Bowerbank Ninow; Max Gimblett at Gow Longsford Gallery; Anne Wallace and Juan Davila at Kalli Rolfe; Christine Webster at Trish Clark; Daniel Unverricht and Richard Lewer at Suite, Toss Woollaston at Page Blackie Gallery, Dame Robin White and Gretchen Albrecht at Two Rooms; Robyn Kahukiwa at Warwick Henderson Gallery; Geoff Thornley at Fox Jensen McCrory; Simon Kaan at Sanderson; James Ormsby at Paulnache and Kai Wasikowski at the Michael Bugelli Gallery.</p> <p>This selective list of names, to which many others can be added, indicates something of the spread and diversity of the artists being presented at the fair – not only in style and medium, but in the whole range of languages of visualisation and conceptualisation. Although there are a few deceased artists included, like Mirdidingkingathi Juwarnda Sally Gabori and Colin McCahon (neither represented by a particularly strong work), like most art fairs there is a predominance of well-established blue chip artists, a scattering of art market darlings plus a few unexpected newcomers.</p> <p>A criticism of art fairs is that they are an expensive market place with high overhead costs, which discourage too much experimentation with “untested” emerging artists. Despite the welcome initiatives of the “projects”, Auckland in this respect falls into line with the pattern of most fairs.</p> <p>The oft-repeated claim that they create a new art audience is also difficult to quantify. Although anecdotal evidence suggests that many who go to fairs may not have ever entered a commercial art gallery before, this does not appear to be followed up by a conversion of this audience into regular gallery goers.</p> <h2>A spectacle</h2> <p>Art fairs and blockbuster exhibitions in public art galleries have become popular people magnet events. They are a form of entertainment that is becoming more of a surrogate for consuming art than some sort of conduit for a return to more traditional patterns of art appreciation and acquisition. They are noisy, crowded and colourful spectacles – more like a party than a quiet arena for the contemplation of art.</p> <p>Is this such a bad thing? Observing the spectacle in Auckland, I was struck by the youthfulness of the thousands of visitors. For many, it seemed the idea that they could afford to purchase an original artwork came as a revelation. Perhaps this was not a $100,000 painting by a major artist, but something more modest and frequently more to their tastes. Nevertheless, new buyers are being introduced to original art and this in itself has to be a positive development.</p> <p>Art fairs globally are breeding a cult of dependency with some “commercial” art galleries increasingly divesting themselves of a physical existence and living from fair to fair. For a while, this was a complete no-no and fairs insisted that participant galleries had a bricks-and-mortar existence, but in many instances the borders are fudged and to be a gallery you need only be an established art trading entity.</p> <p>Art fairs are here to stay; the future of commercial art galleries is far more problematic.</p> <p><em>Image credit: Getty Images</em></p> <p><em>This article first appeared on <a rel="noopener" href="https://theconversation.com/with-commercial-galleries-an-endangered-species-are-art-fairs-a-necessary-evil-116680" target="_blank">The Conversation</a>. </em></p>

Climate change is flooding the remote north with light – and new species

<p>At just over 14 million square kilometres, the Arctic Ocean is the smallest and shallowest of the world’s oceans. It is also the coldest. An expansive raft of sea ice floats near its centre, expanding in the long, cold, dark winter, and contracting in the summer, as the Sun climbs higher in the sky.</p> <p>Every year, usually in September, the sea ice cover shrinks to its lowest level. The tally in 2020 was a meagre 3.74 million square kilometres, the second-smallest measurement in 42 years, and roughly half of what it was in 1980. Each year, as the climate warms, the Arctic is holding onto less and less ice.</p> <p>The effects of global warming are being felt around the world, but nowhere on Earth are they as dramatic as they are in the Arctic. The Arctic is warming two to three times faster than any other place on Earth, ushering in far-reaching changes to the Arctic Ocean, its ecosystems and the 4 million people who live in the Arctic.</p> <p>Some of them are unexpected. The warmer water is pulling some species further north, into higher latitudes. The thinner ice is carrying more people through the Arctic on cruise ships, cargo ships and research vessels. Ice and snow can almost entirely black out the water beneath it, but climate change is allowing more light to flood in.</p> <p><strong>Artificial light in the polar night</strong><br />Light is very important in the Arctic. The algae which form the foundation of the Arctic Ocean’s food web convert sunlight into sugar and fat, feeding fish and, ultimately, whales, polar bears and humans.</p> <p>At high latitudes in the Arctic during the depths of winter, the Sun stays below the horizon for 24 hours. This is called the polar night, and at the North Pole, the year is simply one day lasting six months, followed by one equally long night.</p> <p>Researchers studying the effects of ice loss deployed moored observatories – anchored instruments with a buoy — in an Arctic fjord in the autumn of 2006, before the fjord froze. When sampling started in the spring of 2007, the moorings had been in place for almost six months, collecting data throughout the long and bitter polar night.</p> <p>What they detected changed everything.</p> <p><strong>Life in the dark</strong><br />At that time, scientists assumed the polar night was utterly uninteresting. A dead period in which life lies dormant and the ecosystem sinks into a dark and frigid standby mode. Not much was expected to come of these measurements, so researchers were surprised when the data showed that life doesn’t pause at all.</p> <p>Arctic zooplankton — tiny microscopic animals that eat algae — take part in something called diel vertical migration beneath the ice and in the dead of the polar night. Sea creatures in all the oceans of the world do this, migrating to depth during the day to hide from potential predators in the dark, and surfacing at night to feed.</p> <p>Organisms use light as a cue to do this, so they shouldn’t logically be able to during the polar night. We now understand the polar night to be a riot of ecological activity. The normal rhythms of daily life continue in the gloom. Clams open and close cyclically, seabirds hunt in almost total darkness, ghost shrimps and sea snails gather in kelp forests to reproduce, and deep-water species such as the helmet jellyfish surface when it’s dark enough to stay safe from predators.</p> <p>For most of the organisms active during this period, the Moon, stars and aurora borealis likely give important cues that guide their behaviour, especially in parts of the Arctic not covered by sea ice. But as the Arctic climate warms and human activities in the region ramp up, these natural light sources will in many places be invisible, crowded out by much stronger artificial light.</p> <p><strong>Artificial light</strong><br />Almost a quarter of all land masses are exposed to scattered artificial light at night, as it’s reflected back to the ground from the atmosphere. Few truly dark places remain, and light from cities, coastlines, roads and ships is visible as far as outer space.</p> <p>Even in sparsely populated areas of the Arctic, light pollution is noticeable. Shipping routes, oil and gas exploration and fisheries extend into the region as the sea ice retreats, drawing artificial light into the otherwise inky black polar night.</p> <p>No organisms have had the opportunity to properly adapt to these changes – evolution works on a much longer timescale. Meanwhile, the harmonic movements of the Earth, Moon and Sun have provided reliable cues to Arctic animals for millennia. Many biological events, such as migration, foraging and breeding are highly attuned to their gentle predictability.</p> <p>In a recent study carried out in the high Arctic archipelago of Svalbard, between mainland Norway and the north pole, the onboard lights of a research vessel were found to affect fish and zooplankton at least 200 metres down. Disturbed by the sudden intrusion of light, the creatures swirling beneath the surface reacted dramatically, with some swimming towards the beam, and others swimming violently away.</p> <p>It’s difficult to predict the effect artificial light from ships newly navigating the ice-free Arctic will have on polar night ecosystems that have known darkness for longer than modern humans have existed. How the rapidly growing human presence in the Arctic will affect the ecosystem is concerning, but there are also unpleasant questions for researchers. If much of the information we’ve gathered about the Arctic came from scientists stationed on brightly lit boats, how “natural” is the state of the ecosystem we have reported?</p> <p>Arctic marine science is about to enter a new era with autonomous and remotely operated platforms, capable of operating without any light, making measurements in complete darkness.</p> <p><strong>Underwater forests</strong><br />As sea ice retreats from the shores of Greenland, Norway, North America and Russia, periods with open water are getting longer, and more light is reaching the sea floor. Suddenly, coastal ecosystems that have been hidden under ice for 200,000 years are seeing the light of day. This could be very good news for marine plants like kelp – large brown seaweeds that thrive in cold water with enough light and nutrients.</p> <p>Anchored to the sea floor and floating with the tide and currents, some species of kelp can grow up to 50 metres (175 feet) – about the same height as Nelson’s Column in Trafalgar Square, London. But kelp are typically excluded from the highest latitudes because of the shade cast by sea ice and its scouring effect on the seabed.</p> <p>These lush underwater forests are set to grow and thrive as sea ice shrinks. Kelp are not a new arrival to the Arctic though. They were once part of the traditional Greenlandic diet, and polar researchers and explorers observed them along northern coasts more than a century ago.</p> <p>Some species of kelp may have colonised Arctic coasts after the last ice age, or spread out from small pockets where they’d held on. But most kelp forests in the Arctic are smaller and more restricted to patches in deeper waters, compared to the vast swathes of seaweed that line coasts like California’s in the US.</p> <p>Recent evidence from Norway and Greenland shows kelp forests are already expanding and increasing their ranges poleward, and these ocean plants are expected to get bigger and grow faster as the Arctic warms, creating more nooks for species to live in and around. The full extent of Arctic kelp forests remains largely unseen and uncharted, but modelling can help determine how much they have shifted and grown in the Arctic since the 1950s.</p> <p><strong>A new carbon sink</strong><br />Although large seaweeds come in all shapes and sizes, many are remarkably similar to trees, with long, trunk-like but flexible bodies called stipes. The kelp forest canopy is filled with the flat blades like leaves, while holdfasts act like roots by anchoring the seaweed to rocks below.</p> <p>Some types of Arctic kelp can grow over ten metres and form large and complex canopies suspended in the water column, with a shaded and protected understorey. Much like forests on land, these marine forests provide habitats, nursery areas and feeding grounds for many animals and fish, including cod, pollack, crabs, lobsters and sea urchins.</p> <p>Kelp are fast growers, storing carbon in their leathery tissue as they do. So what does their expansion in the Arctic mean for the global climate? Like restoring forests on land, growing underwater kelp forests can help to slow climate change by diverting carbon from the atmosphere.</p> <p>Better yet, some kelp material breaks off and is swept out of shallow coastal waters and into the deep ocean where it’s effectively removed from the Earth’s carbon cycle. Expanding kelp forests along the Earth’s extensive Arctic coasts could become a growing carbon sink that captures the CO₂ humans emit and locks it away in the deep sea.</p> <p>What’s happening with kelp in the Arctic is fairly unique – these ocean forests are embattled in most other parts of the world. Overall, the global extent of kelp forests is on a downward trend because of ocean heatwaves, pollution, warming temperatures, and outbreaks of grazers like sea urchins.</p> <p>Unsurprisingly, it’s not all good news. Encroaching kelp forests could push out unique wildlife in the high Arctic. Algae living under the ice will have nowhere to go, and could disappear altogether. More temperate kelp species may replace endemic Arctic kelps such as Laminaria solidungula.</p> <p>But kelp are just one set of species among many pushing further and deeper into the region as the ice melts.</p> <p><strong>Arctic invasions</strong><br />Milne Inlet, on north Baffin Island, Nunavut, Canada, sees more marine traffic than any other port in Arctic Canada. Most days during the open-water period, 300-metre-long ships leave the port laden with iron ore from the nearby Mary River Mine. Between 71 and 82 ships pass through the area annually, most heading to — or coming from ports in northern Europe.</p> <p>Cruise ships, coast guard vessels, pleasure yachts, research icebreakers, cargo supply ships and rigid inflatable boats full of tourists also glide through the area. Unprecedented warming and declining sea ice has attracted new industries and other activities to the Arctic. Communities like Pond Inlet have seen marine traffic triple in the past two decades.</p> <p>These ships come to the Arctic from all over the world, carrying a host of aquatic hitchhikers picked up in Rotterdam, Hamburg, Dunkirk and elsewhere. These species — some too small to see with the naked eye — are hidden in the ballast water pumped into on-board tanks to stabilise the ship. They also stick to the hull and other outer surfaces, called “biofouling.”</p> <p>Some survive the voyage to the Arctic and are released into the environment when the ballast water is discharged and cargo loaded. Those that maintain their hold on the outer surface may release eggs, sperm or larvae.</p> <p>Many of these organisms are innocuous, but some may be invasive newcomers that can cause harm. Research in Canada and Norway has already shown non-native invasive species like bay and acorn barnacles can survive ship transits to the Arctic. This raises a risk for Arctic ecosystems given that invasive species are one of the top causes for extinctions worldwide.</p> <p><strong>Expanded routes</strong><br />Concern about invasive species extends far beyond the community of Pond Inlet. Around 4 million people live in the Arctic, many of them along the coasts that provide nutrients and critical habitat for a wide array of animals, from Arctic char and ringed seals to polar bear, bowhead whales and millions of migratory birds.</p> <p>As waters warm, the shipping season is becoming longer, and new routes, like the Northwest Passage and the Northern Sea Route (along Russia’s Arctic coast), are opening up. Some researchers expect a trans-Arctic route across the North Pole might be navigable by mid-century. The increased ship traffic magnifies the numbers and kinds of organisms transported into Arctic waters, and the progressively more hospitable conditions improve their odds of survival.</p> <p>Prevention is the number one way to keep invasive species out of the Arctic. Most ships must treat their ballast water, using chemicals or other processes, and/or exchange it to limit the movement of harmful organisms to new locations. Guidelines also recommend ships use special coatings on the hulls and clean them regularly to prevent biofouling. But these prevention measures are not always reliable, and their efficacy in colder environments is poorly understood.</p> <p>The next best approach is to detect invaders as soon as possible once they arrive, to improve chances for eradication or suppression. But early detection requires widespread monitoring, which can be challenging in the Arctic. Keeping an eye out for the arrival of a new species can be akin to searching for a needle in a haystack, but northern communities may offer a solution.</p> <p>Researchers in Norway, Alaska and Canada have found a way to make that search easier by singling out species that have caused harm elsewhere and that could endure Arctic environmental conditions. Nearly two dozen potential invaders show a high chance for taking hold in Arctic Canada.</p> <p>Among these is the cold-adapted red king crab, native to the Sea of Japan, Bering Sea and North Pacific. It was intentionally introduced to the Barents Sea in the 1960s to establish a fishery and is now spreading south along the Norwegian coast and in the White Sea. It is a large, voracious predator implicated in substantial declines of harvested shellfish, sea urchins and other larger, slow moving bottom species, with a high likelihood of surviving transport in ballast water.</p> <p>Another is the common periwinkle, which ruthlessly grazes on lush aquatic plants in shoreline habitats, leaving behind bare or encrusted rock. It has also introduced a parasite on the east coast of North America that causes black spot disease in fishes, which stresses adult fishes and makes them unpalatable, kills juveniles and causes intestinal damage to birds and mammals that eat them.</p> <p><strong>Tracking genetic remnants</strong><br />New species like these could affect the fish and mammals people hunt and eat, if they were to arrive in Pond Inlet. After just a few years of shipping, a handful of possibly non-native species have already been discovered, including the invasive red-gilled mudworm (Marenzellaria viridis), and a potentially invasive tube dwelling amphipod. Both are known to reach high densities, alter the characteristics of the seafloor sediment and compete with native species.</p> <p>Baffinland, the company that runs the Mary River Mine, is seeking to double its annual output of iron ore. If the expansion proceeds, up to 176 ore carriers will pass through Milne Inlet during the open-water season.</p> <p>Although the future of Arctic shipping remains uncertain, it’s an upward trend that needs to be watched. In Canada, researchers are working with Indigenous partners in communities with high shipping activity — including Churchill, Manitoba; Pond Inlet and Iqaluit in Nunavut; Salluit, Quebec and Nain, Newfoundland — to establish an invasive species monitoring network. One of the approaches includes collecting water and testing it for genetic remnants shed from scales, faeces, sperm and other biological material.</p> <p>This environmental DNA (eDNA) is easy to collect and can help detect organisms that might otherwise be difficult to capture or are in low abundance. The technique has also improved baseline knowledge of coastal biodiversity in other areas of high shipping, a fundamental step in detecting future change.</p> <p>Some non-native species have already been detected in the Port of Churchill using eDNA surveillance and other sampling methods, including jellyfish, rainbow smelt and an invasive copepod species.</p> <p>Efforts are underway to expand the network across the Arctic as part of the Arctic Council’s Arctic Invasive Alien Species Strategy to reduce the spread of invasive species.</p> <p>The Arctic is often called the frontline of the climate crisis, and because of its rapid rate of warming, the region is beset by invasions of all kinds, from new species to new shipping routes. These forces could entirely remake the ocean basin within the lifetimes of people alive today, from frozen, star-lit vistas, populated by unique communities of highly adapted organisms, to something quite different.</p> <p>The Arctic is changing faster than scientists can document, yet there will be opportunities, such as growing carbon sinks, that could benefit the wildlife and people who live there. Not all changes to our warming world will be wholly negative. In the Arctic, as elsewhere, there are winners and losers.</p> <p class="p1"><em>Written by Jørgen Berge. This article first appeared on <a href="https://theconversation.com/arctic-ocean-climate-change-is-flooding-the-remote-north-with-light-and-new-species-150157">The Conversation</a>.</em></p>

Why marine protected areas are often not where they should be

<p>There’s no denying the grandeur and allure of a nature reserve or marine protected area. The concept is easy to understand: limit human activity there and marine ecosystems will thrive.</p> <p>But while the number of marine protected areas is increasing, so too is the number of threatened species, and the health of marine ecosystems is <a href="https://ipbes.net/global-assessment">in decline</a>.</p> <p>Why? <a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/cobi.13429">Our research</a> shows it’s because marine protected areas are often placed where there’s already low human activity, rather than in places with high biodiversity that need it most.</p> <p><strong>Not where they should be</strong></p> <p>Many parts of the world’s protected areas, in both terrestrial and marine environments, are placed in locations with no form of manageable human activity or development occurring, such as fishing or infrastructure. These places are often remote, such as in the centres of oceans.</p> <p>And where marine protected areas have been increasing, they’re placed where <a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/cobi.13429">pressures cannot be managed</a>, such as areas where there is increased ocean acidification or dispersed pollution.</p> <p>But biodiversity is often highest in the places with human activity – we use these locations in the ocean to generate income and livelihoods, from tourism to fishing. This includes coastal areas in the tropics, such as the Coral Triangle (across six countries including Indonesia, the Philippines and Malaysia), which has almost <a href="https://ccafs.cgiar.org/publications/marine-protected-areas-coral-triangle-progress-issues-and-options">2,000 marine protected areas</a>, yet is <a href="https://theconversation.com/why-seagrass-in-indonesias-marine-protected-areas-is-still-under-threat-125875">also home</a> to one of the largest shipping routes in the world and high fishing activity.</p> <p>What’s more, many marine industries are already regulated through licences and quotas, so it’s hard to establish a new marine protected area that adds a different type of management on top of what already exists.</p> <p>This leaves us with an important paradox: the places where biodiversity is under the most pressure are also the places humanity is most reluctant to relinquish, due to their social or economic value. Because of those values, people and industry resist changes to behaviour, leaving governments to try to find solutions that avoid conflict.</p> <p><strong>Lessons from the fishing industry</strong></p> <p>How can we resolve the paradox of marine protected areas? A strategy used in the fishing industry may show the way.</p> <p>Fisheries have had experience in going beyond the limits of sustainability and then stepping back, changing their approach to managing species and ecosystems for better sustainability, while still protecting economic, social and environmental values.</p> <p>In the past, many of the world’s fisheries regularly exceeded the sustainable limit of catches, and many species such as <a href="https://www.ccsbt.org/en/content/latest-stock-assessment">southern bluefin tuna</a> declined significantly in number. But <a href="https://www.pnas.org/content/117/4/2218">strong rules around how a fishery should operate</a> mean declines have since been reversed.</p> <p>So how did they do it? In recent decades, many of the world’s large-scale fisheries implemented formal “harvest strategies”. These strategies can flip downward trends of marine species in places not designated a marine protected area.</p> <p>Harvest strategies have three steps. First is pre-agreed monitoring of species and ecosystems by fishers, regulators and other stakeholders. Second, regulators and scientists assess their impact on the species and ecosystems. And last, all stakeholders agree to put management measures in place to improve the status of the monitored species and ecosystems.</p> <p>These measures may include changing how fishing is done or how much is done. It’s a commonsense strategy that’s delivered <a href="https://theconversation.com/marine-parks-and-fishery-management-whats-the-best-way-to-protect-fish-66274">successful results</a> with many fished species either recovering or recovered.</p> <p>In Australia, the federal government introduced a <a href="https://www.agriculture.gov.au/sites/default/files/sitecollectiondocuments/fisheries/domestic/harvest-strategy-policy.docx">formal harvest strategy policy</a> to manage fisheries in 2007. It was evaluated in <a href="https://academic.oup.com/icesjms/article/71/2/195/788673">2014</a>, and the report found many (but not all) fish stocks are no longer overfished. This includes species such as orange roughy and southern bluefin tuna in Australia, which were overfished but are no longer so.</p> <p>But unfortunately, this positive trend has not been replicated for biodiversity hit by the combinations of other human activities such as coastal development, transport, oil and gas extraction and marine debris.</p> <p><strong>A consistent strategy</strong></p> <p>We need to adapt the experience from fisheries and apply a single, formal, transparent and agreed <em>biodiversity</em> strategy that outlines sustainable management objectives for the places we can’t put marine protected areas.</p> <p>This would look like a harvest strategy, but be applied more broadly to threatened species and ecosystems. What might be sustainable from a single species point of view as used in the fisheries might not sustainable for multiple species.</p> <p>This would mean for our threatened species, we would be monitoring their status, assessing whether the <em>total</em> population was changing and agreeing on when and how we would change the way that they are impacted.</p> <p>Such a strategy would also allow monitoring of whole marine ecosystems, even when information is limited. Information on trends in species and ecosystems often exists, but is hidden as commercial-in-confidence or kept privately within government, research or commercial organisations.</p> <p><strong>Looking ahead</strong></p> <p>Still, a lack of data shouldn’t limit decision making. Experience in fisheries without much data shows even rules of thumb can be <a href="https://doi.org/10.1016/j.fishres.2014.11.005">effective management tools</a>. Rules of thumb can include simple measures like gear restrictions or spatial or temporal closures that don’t change through time.</p> <p>Moving forward, all stakeholders need to agree to implement the key parts of harvest strategies for all marine places with high biodiversity that aren’t protected. This will complement existing marine protected area networks without limiting economic activity, while also delivering social and environmental outcomes that support human well-being.</p> <p>Our marine ecosystems provide fish, enjoyment, resources and and simple beauty. They must survive for generations to come.</p> <p><em>Written by Piers Dunstan, Natalie Downing, Simone Stevenson and Skipton Woolley.

Hundreds of koalas brutally murdered during routine logging

<p>WARNING: GRAPHIC IMAGES</p> <p>A few hundred of perhaps Australia’s most beloved animal, koalas, have reportedly been murdered in Victoria this week.</p> <p>Animals Australia has shared devastating images of injured and dead koalas who were “mowed down” after logging occurred 12km west of Portland.</p> <blockquote class="twitter-tweet"> <p dir="ltr">On becoming aware of this situation on Friday, we flew in a veterinary team from <a href="https://twitter.com/Vets_Compassion?ref_src=twsrc%5Etfw">@Vets_Compassion</a>.

Six million hectares of threatened species habitat up in smoke

<p>More than <a href="https://sydney.edu.au/news-opinion/news/2020/01/08/australian-bushfires-more-than-one-billion-animals-impacted.html">one billion mammals, birds, and reptiles</a> across eastern Australia are estimated to have been affected by the current fire catastrophe.</p> <p>Many animals and plants have been incinerated or suffocated by smoke and ash. Others may have escaped the blaze only to die of exhaustion or starvation, or be picked off by predators.</p> <p>But even these huge losses of individual animals and plants do not reveal the full scale of impact that the recent fires have had on biodiversity.</p> <p>Plants, <a href="https://theconversation.com/australias-bushfires-could-drive-more-than-700-animal-species-to-extinction-check-the-numbers-for-yourself-129773">invertebrates</a>, freshwater fish, and frogs have also been affected, and the impact of the fires is likely to be disproportionately greater for <a href="https://theconversation.com/a-season-in-hell-bushfires-push-at-least-20-threatened-species-closer-to-extinction-129533">threatened species</a>.</p> <p>To delve deeper into the conservation impact, we used publicly available satellite imagery to look at the burnt areas (up to January 7, 2020) and see how they overlapped with the approximate distributions of all the threatened animals and plants listed under the Environment Protection and Biodiversity Conservation Act.</p> <p>We restricted our analysis to the mediterranean and temperate zone of south-east and south-west Australia.</p> <p><strong>The bad news</strong></p> <p>We found that 99% of the area burned in the current fires contains potential habitat for at least one nationally listed threatened species. We conservatively estimate that six million hectares of threatened species habitat has been burned.</p> <p>Given that many fires are still burning and it is not yet clear how severe the burning has been in many areas, the number of species affected and the extent of the impact may yet change.</p> <p>What we do know is that these species are already on the brink of extinction due to other threats, such as <a href="https://theconversation.com/environment-laws-have-failed-to-tackle-the-extinction-emergency-heres-the-proof-122936">land clearing</a>, invasive species, climate change, disease, or previous fires.</p> <p>Approximately 70 nationally threatened species have had at least 50% of their range burnt, while nearly 160 threatened species have had more than 20% of their range burnt.</p> <p>More threatened plants have been affected than other groups: 209 threatened plant species have had more than 5% of their range burnt compared to 16 mammals, ten frogs, six birds, four reptiles, and four freshwater fish.</p> <p>Twenty-nine of the 30 species that have had more than 80% of their range burnt are plants. Several species have had their entire range consumed by the fires, such as the Mountain Trachymene, a <a href="http://www.environment.gov.au/biodiversity/threatened/species/pubs/9367-conservation-advice.pdf">fire-sensitive</a> plant found in only four locations in the South Eastern Highlands of NSW.</p> <p>Other species that have been severely impacted include the Kangaroo Island dunnart and the Kangaroo Island glossy black cockatoo. These species’ entire populations numbered only in the hundreds prior to these bushfires that have burned more than 50% of their habitat.</p> <p>Glossy black cockatoos have a highly specialised diet. They eat the seeds of the drooping sheoak <a href="https://ecos.csiro.au/glossy-black-cockatoos/">(<em>Allocasuarina verticillata</em>).</a> These trees may take anywhere from 10 to 50 years to recover enough to produce sufficient food for the black cockatoos.</p> <p>The populations of many species will need careful management and protection to give their habitats enough time to recover and re-supply critical resources.</p> <p>The figures above do not account for cumulative impacts of previous fires. For example, the critically endangered western ground parrot had around 6,000 hectares of potential habitat burnt in these fires, which exacerbates the impact of earlier extensive fires in 2015 and early 2019.</p> <p>Threatened species vary in their ability to cope with fire. For fire-sensitive species, almost every individual dies or is displaced. The long-term consequences are likely to be dire, particularly if vegetation composition is irrevocably changed by severe fire or the area is subject to repeat fires.</p> <p>More than 50% of the habitat of several species known to be susceptible to fire has been burnt – these include the long-footed potoroo and Littlejohn’s tree frog.</p> <p>Some species are likely to thrive after fire. Indeed, of the top 30 most impacted species on our list, almost 20% will likely flourish due to low competition in their burnt environments – these are all re-sprouting plants. Others will do well if they are not burnt again before they can set seed.</p> <p><strong>Rising from the ashes</strong></p> <p>For fire-sensitive threatened species, these fires could have substantially increased the probability of extinction by virtue of direct mortality in the fires or reducing the amount of suitable habitat. However, after the embers settle, with enough investment and conservation actions, guided by evidence-based science, it may be possible to help threatened species recover.</p> <p>Protection and conservation-focussed management of areas that have not burned will be the single most important action if threatened species are to have any chance of persistence and eventual recovery.</p> <p>Management of threatening processes (such as weeds, feral predators, <a href="https://theconversation.com/double-trouble-as-feral-horse-numbers-gallop-past-25-000-in-the-australian-alps-128852">introduced herbivores</a>, and habitat loss through logging or thinning) must occur not just at key sites, but across the landscapes they sit in.

Australian bushfires could drive more than 700 animal species to extinction

<p>The scale and speed of the current bushfire crisis has caught many people off-guard, including biodiversity scientists. People are scrambling to estimate the long-term effects. It is certain that many animal species will be pushed to the brink of extinction, but how many?</p> <p>One recent article suggested <a href="https://theconversation.com/a-season-in-hell-bushfires-push-at-least-20-threatened-species-closer-to-extinction-129533">20 to 100</a>, but this estimate mostly considers large, well-known species (especially mammals and birds).</p> <p>A far greater number of smaller creatures such as insects, snails and worms will also be imperilled. They make up the bulk of biodiversity and are the little rivets holding ecosystems together.</p> <p>But we have scant data on how many species of <a href="https://www.abc.net.au/news/science/2020-01-08/insects-invertebrates-frogs-affected-by-bushfire/11843458">small creatures</a> have been wiped out in the fires, and detailed surveys comparing populations before and after the fires will not be forthcoming. So how can we come to grips with this silent catastrophe?<span class="attribution"><span class="source"> </span></span></p> <p>Using the information that is available, I calculate that at least 700 animal species have had their populations decimated – and that’s only counting the insects.</p> <p>This may sound like an implausibly large figure, but the calculation is a simple one. I’ll explain it below, and show you how to make your own extinction estimate with only a few clicks of a calculator.</p> <p><strong>Using insects to estimate true extinction numbers</strong></p> <p>More than <a href="https://www.environment.gov.au/science/abrs/publications/other/numbers-living-species/contents">three-quarters</a> of the known animal species on Earth are insects. To get a handle on the true extent of animal extinctions, insects are a good place to start.</p> <p>My estimate that 700 insect species are at critical risk involves <a href="https://conservationbytes.com/2011/07/26/predicting-marine-biodiversity/">extrapolating</a> from the information we have about the catastrophic effect of the fires on mammals.</p> <p>We can work this out using only two numbers: <em>A</em>, how many mammal species are being pushed towards extinction, and <em>B</em>, how many insect species there are for each mammal species.</p> <p>To get a “best case” estimate, I use the most conservative estimates for <em>A</em> and <em>B</em> below, but jot down your own numbers.</p> <p><strong>How many mammals are critically affected?</strong></p> <p>A <a href="https://time.com/5761083/australia-bushfires-biodiversity-plants-animals/">recent Time article</a> lists four mammal species that will be severely impacted: the long-footed potoroo, the greater glider, the Kangaroo Island dunnart, and the black-tailed dusky antechinus. The eventual number could be much greater (e.g the <a href="https://www.theguardian.com/environment/2020/jan/04/ecologists-warn-silent-death-australia-bushfires-endangered-species-extinction">Hastings River mouse</a>, the <a href="https://www.sciencemag.org/news/2019/12/fires-rage-across-australia-fears-grow-rare-species">silver-headed antechinus</a>), but let’s use this most optimistic (lowest) figure (<em>A</em> = 4).</p> <p>Make your own estimate of this number <em>A</em>. How many mammal species do you think would be pushed close to extinction by these bushfires?</p> <p>We can expect that for every mammal species that is severely affected there will be a huge number of insect species that suffer a similar fate. To estimate exactly how many, we need an idea of insect biodiversity, relative to mammals.</p> <p><strong>How many insect species are out there, for each mammal species?</strong></p> <p>The world has around <a href="https://www.environment.gov.au/science/abrs/publications/other/numbers-living-species#downloads">1 million</a> named insect species, and around <a href="https://www.environment.gov.au/science/abrs/publications/other/numbers-living-species#downloads">5,400 species</a> of land mammals.</p> <p>So there are at least 185 insect species for every single land mammal species (<em>B</em> = 185). If the current bushfires have burnt enough habitat to devastate 4 mammal species, they have probably taken out around 185 × 4 = 740 insect species in total. Along with many species of other invertebrates such as spiders, snails, and worms.</p> <p><a href="https://images.theconversation.com/files/309629/original/file-20200113-103971-8f6187.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/309629/original/file-20200113-103971-8f6187.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a> <span class="caption">There are hundreds of insect species for every mammal species.</span> <span class="attribution"><span class="source">https://imgbin.com/</span></span></p> <p>For your own value for <em>B</em>, use your preferred estimate for the number of insect species on earth and divide it by 5,400 (the number of land mammal species).</p> <p>One recent study suggests there are at least <a href="https://www.mirror.co.uk/news/technology-science/science/far-fewer-species-animals-plants-5803977">5.5 million</a> species of insects, giving a value of <em>B</em> of around 1,000. But there is reason to suspect the real number could be <a href="https://theconversation.com/the-earths-biodiversity-could-be-much-greater-than-we-thought-61665">much greater</a>.</p> <p><strong>How do our estimates compare?</strong></p> <p>My “best case” values of <em>A</em> = 4 and <em>B</em> = 185 indicate at least 740 insect species alone are being imperilled by the bushfires. The total number of animal species impacted is obviously much bigger than insects alone.</p> <p>Feel free to perform your own calculations. Derive your values for <em>A</em> and <em>B</em> as above. Your estimate for the number of insect species at grave risk of extinction is simply <em>A</em> × <em>B</em>.</p> <p>Post your estimate and your values for <em>A</em> and <em>B</em> please (and how you got those numbers if you wish) in the Comments section and compare with others. We can then see what the wisdom of the crowd tells us about the likely number of affected species.</p> <p><strong>Why simplistic models can still be very useful</strong></p> <p>The above calculations are a hasty estimate of the magnitude of the current biodiversity crisis, done on the fly (figuratively and literally). Technically speaking, we are using mammals as <a href="https://conservationbytes.com/2011/07/26/predicting-marine-biodiversity/">surrogates</a> or <a href="https://methodsblog.com/2018/10/08/biodiversity-vascular-plants/">proxies</a> for insects.</p> <p>To improve these estimates in the near future, we can try to get more exact and realistic estimates of <em>A</em> and <em>B</em>.</p> <p>Additionally, the model itself is very simplistic and can be refined. For example, if the average insect is <a href="https://blog.csiro.au/the-impact-of-bushfires-on-australian-insects/">more susceptible</a> to fire than the average mammal, our extinction estimates need to be revised upwards.</p> <p>Also, there might be an unusually high (or low) ratio of insect species compared to mammal species in fire-affected regions. Our model assumes these areas have the global average – whatever that value is!</p> <p>And most obviously, we need to consider terrestrial life apart from insects – land snails, spiders, worms, and plants too – and add their numbers in our extinction tally.</p> <p>Nevertheless, even though we know this model gives a huge underestimate, we can still use it to get an absolute lower limit on the magnitude of the unfolding biodiversity crisis.</p> <p>This “best case” is still very sad. There is a strong argument that these unprecedented bushfires could cause one of biggest extinction events in the modern era. And these infernos will burn for a while longer yet.<!-- Below is The Conversation's page counter tag.

High-tech fishing gear could help save endangered right whales

<p>Many fish, marine mammals and seabirds that inhabit the world’s oceans are critically endangered, but few are as close to the brink as the North Atlantic right whale (<em>Eubalaena glacialis</em>). <a href="https://www.narwc.org/uploads/1/1/6/6/116623219/2018report_cardfinal.pdf">Only about 411 of these whales exist today</a>, and at their current rate of decline, they could become extinct within our lifetimes.</p> <p>From 1980 through about 2010, conservation efforts focused mainly on protecting whales from being struck by ships. Federal regulations helped <a href="https://www.fisheries.noaa.gov/national/endangered-species-conservation/reducing-ship-strikes-north-atlantic-right-whales">reduce vessel collisions</a> and supported a slight rebound in right whale numbers.</p> <p>But at the same time, growing numbers of right whales died after becoming entangled in lobster and crab fishing gear, and the population has taken a significant downward turn. This may have happened because fishing ropes became stronger, and both whales and fishermen shifted their ranges so that areas of overlap increased. In research that is <a href="https://www.int-res.com/prepress/d03376.html">currently in press</a>, we show that 72% of diagnosed mortalities between 2010-2018 occurred due to entanglements.</p> <p>This comes after a millennium of whaling that decimated the right whale population, reducing it from perhaps between <a href="https://doi.org/10.1111/cobi.12664">10,000 to 20,000</a> to a few hundred animals today. And entanglement deaths are <a href="http://dx.doi.org/10.1155/2012/230653">much more inhumane</a> than harpoons. A whaler’s explosive harpoon kills quickly, compared to months of drawn-out pain and debilitation caused by seemingly harmless fishing lines. We believe these deaths can be prevented by working with the trap fishing industries to adopt <a href="https://ropeless.org/">ropeless fishing gear</a> – but North Atlantic right whales are running out of time.</p> <p><strong>Deadly encounters</strong></p> <p>Whalers pursued right whales for centuries because this species swam relatively slowly and floated when dead, so it was easier to kill and retrieve than other whales. By the mid-20th century, scientists assumed they had been hunted to extinction. But in 1980, researchers from the New England Aquarium who were studying marine mammal distribution in the Bay of Fundy off eastern Canada were stunned when they <a href="https://www.canadianwhaleinstitute.ca/habitats">sighted 26 right whales</a>.</p> <p>Conservation efforts led to the enactment of regulations that required commercial ships to <a href="https://www.fisheries.noaa.gov/national/endangered-species-conservation/reducing-ship-strikes-north-atlantic-right-whales">slow down</a> in zones along the U.S. Atlantic coast where they were highly likely to encounter whales, reducing boat strikes. But this victory has been offset by rising numbers of entanglements.</p> <p>Adult right whales can produce up to an estimated <a href="https://doi.org/10.1111/mms.12230">8,000 pounds of force</a> with a single stroke of their flukes. When they become tangled in fishing gear, they often break it and swim off trailing ropes and sometimes crab or lobster traps.</p> <p>Lines and gear can wrap around a whale’s body, flukes, flippers and mouth. They impede swimming and feeding, and cause chronic infection, emaciation and damage to blubber, muscle and bone. Ultimately these injuries weaken the animal until it dies, <a href="https://doi.org/10.1093/icesjms/fsu008">which can take months to years</a>.</p> <p>One of us, <a href="https://scholar.google.com/citations?hl=en&amp;user=DQ-fD1QAAAAJ">Michael Moore</a>, is trained as a veterinarian and has examined many entangled dead whales. Moore has seen fishing rope embedded inches deep into a whale’s lip, and a juvenile whale whose spine had been deformed by the strain of dragging fishing gear. Other animals had flippers nearly severed by swimming wrapped in inexorably constricting ropes. Entanglement injuries to right whales are the worst animal trauma Moore has seen in his career.</p> <p>Even if whales are able to wriggle free and live, the extreme stress and energy demands of entanglement, along with inadequate nutrition, are thought to be <a href="https://doi.org/10.1002/ece3.2615">preventing females from getting pregnant</a> and contributing to record low calving rates in recent years.</p> <p><strong>Solutions for whales and fishermen</strong></p> <p>The greatest entanglement risk is from ropes that lobster and crab fishermen use to attach buoys to traps they set on the ocean floor. Humpback and minke whales and leatherback sea turtles, all of which are federally protected, also become entangled.</p> <p>Conservationists are looking for ways to modify or eliminate these ropes. Rock lobster fishermen in Australia already use <a href="https://www.youtube.com/watch?v=WeeieRr7sTw">pop-up buoys</a> that ascend when they receive sound signals from fishing boats. The buoys trail out ropes as they rise, which fishermen retrieve and use to pull up their traps.</p> <p>Other technologies are <a href="https://www.wnpr.org/post/innovations-fishing-gear-could-change-lobster-industry-help-endangered-right-whale">in development</a>, including systems that <a href="https://ropeless.org/november-6th-2018-presentations/">acoustically identify traps on the seafloor</a> and mark them with “virtual buoys” on fishermen’s chart plotters, eliminating the need for surface buoys. Fishermen also routinely use a customized hook on the end of a rope to catch the line between traps and haul them to the surface when the buoy line goes missing.</p> <p>Transitioning to ropeless technology will require a sea change in some of North America’s most valuable fisheries. The 2016 U.S. lobster catch was worth <a href="https://www.st.nmfs.noaa.gov/commercial-fisheries/commercial-landings/annual-landings/index">US$670 million</a>. Canadian fishermen landed <a href="http://www.dfo-mpo.gc.ca/stats/commercial/land-debarq/sea-maritimes/s2016av-eng.htm">CA$1.3 billion</a> worth of lobster and <a href="http://www.dfo-mpo.gc.ca/stats/commercial/land-debarq/sea-maritimes/s2016av-eng.htm">CA$590 million</a> worth of snow crab.</p> <p>Just as no fisherman wants to catch a whale, researchers and conservationists don’t want to put fishermen out of business. In our view, ropeless technologies offer a genuine opportunity for whales and the fishing industry to co-exist if they can be made functional, affordable and safe to use.</p> <p>Switching to ropeless gear is <a href="https://www.smithsonianmag.com/innovation/lobster-trap-aims-protect-endangered-whalesand-fishers-livelihoods-180971208/">unlikely to be cheap</a>. But as systems evolve and simplify, and production scales up, they will become more affordable. And government support could help fishermen make the shift. In Canada, the federal and New Brunswick provincial governments recently awarded CA$2 million to Canadian snow crab fishermen to <a href="https://www.cbc.ca/news/canada/new-brunswick/snow-crab-right-whale-fishing-gear-research-1.5143321">test two ropeless trap designs</a>.</p> <p>Converting could save fishermen money in the long run. For example, California Dungeness crab fishermen closed their 2019 season three months ahead of schedule on April 15 to settle a lawsuit over whale entanglements, leaving crab they could have caught still in the water. Under the agreement, fishermen using ropeless gear will be <a href="https://www.nationalfisherman.com/west-coast-pacific/dungeness-drag/">exempt from future early closures</a>.</p> <p><strong>A rebound is possible</strong></p> <p>The <a href="https://www.fws.gov/endangered/laws-policies/">Endangered Species Act</a> and <a href="https://www.fws.gov/international/laws-treaties-agreements/us-conservation-laws/marine-mammal-protection-act.html">Marine Mammal Protection Act</a> require the U.S. government to conserve endangered species. In Congress, the pending <a href="https://www.congress.gov/bill/116th-congress/house-bill/1568/text?q=%7B%22search%22%3A%5B%22H.R.+3729%22%5D%7D">SAVE Right Whales Act of 2019</a> would provide $5 million annually for collaborative research into preventing mortalities caused by the fishing and shipping industries. And an advisory committee to the U.S. National Oceanic and Atmospheric Administration recently recommended <a href="https://www.fisheries.noaa.gov/feature-story/team-reaches-nearly-unanimous-consensus-right-whale-survival-measures">significant fishing protections</a>, focused primarily on reducing the number of ropes in the water column and the strength of the remaining lines.</p> <p>Consumers can also help. Public outcry over dolphin bycatch in tuna fisheries spurred passage of the Marine Mammal Protection Act and led to <a href="https://swfsc.noaa.gov/textblock.aspx?Division=PRD&amp;ParentMenuId=228&amp;id=1408">dolphin-safe tuna labeling</a>, which ultimately reduced dolphin mortalities from half a million to about 1,000 animals annually. Choosing lobster and crab products <a href="https://doi.org/10.1093/icesjms/fsy194">caught without endangering whales</a> could accelerate a similar transition.</p> <p>North Atlantic right whales can still thrive if humans make it possible. The closely related southern right whale (<em>Eubalaena australis</em>), which has faced few human threats since the end of commercial whaling, has rebounded from just 300 animals in the early 20th century to an <a href="https://www.fisheries.noaa.gov/resource/document/southern-right-whale-eubalaena-australis-5-year-review-summary-and-evaluation">estimated 15,000 in 2010</a>.</p> <p>There are real ways to save North Atlantic right whales. If they go extinct, it will be on this generation’s watch.</p> <p><em>Editor’s note: This article was updated on May 28, 2019 to correct the number of North Atlantic right whale deaths in recent years that were caused by entanglements.</em><!-- Below is The Conversation's page counter tag.
