Our dogs can terrify (and even kill) wildlife. Here’s how to be a responsible owner this summer

<p><em><a href="https://theconversation.com/profiles/melissa-starling-461103">Melissa Starling</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>In Australia, dog ownership often goes hand-in-hand with a love for the great outdoors. Whether it’s walking on the beach, going camping, or having a barbecue in the park, we tend to keep our canine companions close as we soak up the sun.</p> <p>But many of us forget a key fact about our dogs: they are predators. Even the fluffy little 5kg ball that spends most of its time in your lap derives from an apex predator – and its predatory instincts can kick in at any time.</p> <p>And while many of our dogs don’t have the same hunting skills as their distant ancestors (who had to hunt for a living), wildlife doesn’t know that.</p> <p>The impacts of domestic dogs on wildlife aren’t well studied, and likely vary depending on the environment. Nonetheless, there’s good evidence domestic dogs, when left unobserved, can have detrimental effects in the places they visit.</p> <p>With that in mind, here are some things to consider next time you take your pup out for a bushwalk.</p> <h2>How dogs impact ecosystems</h2> <p>There are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320717305967">five main ways</a> domestic dogs can negatively impact the natural environments they visit. These are:</p> <ol> <li>direct physical harm through predatory behaviour</li> <li>disturbance through chasing and harassment</li> <li>increased exposure to diseases</li> <li>interbreeding, which can alter the gene pool of wild canid populations</li> <li>increased competition for resources.</li> </ol> <p>The good news is the last three points aren’t particularly relevant in Australia. For one thing, there’s little overlap between diseases common in domestic dogs and Australian wildlife. There’s also little resource overlap, except perhaps in some areas where feral or semi-feral dogs live alongside dingoes.</p> <p>And regarding potential interbreeding, while it was once thought this could threaten the dingo gene pool, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/mec.16998">recent research</a> suggests it’s not nearly as common as we thought.</p> <p>As such, the main harms Aussie dog owners should focus on are physical harms through predatory behaviour and disturbance to ecosystems.</p> <h2>Dogs can kill</h2> <p>We know dogs are capable of injuring and killing wildlife, but it’s difficult to determine how common this is, because many events go unreported. While smaller animals such as lizards, gliders and possums are at higher risk, larger species such as koalas can also fall prey to dogs.</p> <p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0206958">One study</a> that looked at wildlife coming into care at Queensland rehabilitation centres reported dog attacks as the cause in about 9% of cases. These cases often resulted in severe injury or death.</p> <p>Dog owners should be especially wary of small, localised populations of vulnerable species. A <a href="https://ri.conicet.gov.ar/bitstream/handle/11336/202640/CONICET_Digital_Nro.29048152-7a5c-4ea2-8068-e73d42cba01d_B.pdf?sequence=2&isAllowed=y">study</a> in Argentina’s Patagonia region details several cases of dogs decimating local penguin populations after gaining access to protected island areas during low tide.</p> <p>Not to mention, dog attacks on wildlife can bring risk to dogs as well. Kangaroos can defend themselves with <a href="https://www.abc.net.au/news/2023-10-16/mildura-man-fights-kangaroo-to-protect-dog/102983926">their powerful limbs</a>, monitor lizards are equipped with sharp claws and teeth, and many snake species <a href="https://www.brisbanetimes.com.au/national/queensland/dogs-twice-as-likely-to-die-from-snake-bite-as-cats-research-finds-20200519-p54ufd.html">are highly venomous</a>.</p> <h2>The impact of harassment</h2> <p>You might think it’s harmless for your dog to chase wildlife if it never manages to catch the animals it chases, but that isn’t true. Wild animals optimise their behaviours to meet their needs for foraging, breeding and resting, and being chased by a dog can disrupt this.</p> <p>For example, certain threatened bird species will nest on the beach and find foraging opportunities based on the tides. One dog forcing one bird to abandon this important activity may have a small impact. But if it happens repeatedly throughout the day, it can become a <a href="https://wilderness-society.org/wp-content/uploads/2019/04/Dogs-as-agents-of-disturbance-Michael-A.-Weston-and-Theodore-Stankowich.pdf">much bigger problem</a>. It may even drive animals out of the area.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2391219/">Research</a> conducted in Sydney has shown the mere presence of a leashed dog is enough to temporarily, yet dramatically, reduce the number of bird species detected.</p> <h2>Keep an eye on your furry pal</h2> <p>Responsible dog ownership involves making sure our dogs have a minimal impact on others, including wildlife. How can we achieve this when our dogs are simply engaging in behaviours that come naturally to them, and may even be rewarding for them?</p> <p>Training your dog to have general obedience – especially to come when called – is worth sinking considerable time and effort into. This can save both your dog and any wildlife they may be after. For instance, calling a dog away from a snake is one of the most effective ways of managing snake bite risk.</p> <p>One <a href="https://www.researchgate.net/publication/333344634_Applying_Social_Marketing_to_Koala_Conservation_The_Leave_It_Pilot_Program">pilot study</a> in Victoria found positive outcomes from a program that helped owners train their dogs to be more obedient around wildlife.</p> <p>That said, recall training is an art form, and recalling a dog that likes to run off and chase animals can be a huge challenge.</p> <p>Another solution is to rely on leashes when passing sensitive areas, or where there’s a risk of wildlife harassment. In Australia, many beaches that allow dogs have signs with information about vulnerable birds in the area and how to protect them from your dog.</p> <p>This could mean keeping your dog off rock platforms, leashing them when you see birds foraging on the beach, or keeping them out of fenced areas. Some areas are simply too vulnerable for dogs to run amok, so always look for signs and read them carefully.</p> <p>If you’re hiking, use a long line (a leash that’s more than five metres long) and look for signs of your dog detecting something of interest. Often their ears will come up high and forward, and they will freeze and stare intently.</p> <p>At this point, it doesn’t matter what they’re excited about: take the opportunity to leash them or shorten their leash, and get their attention before they can take off. Investing in a long leash will allow your dog more freedom without putting wildlife at risk.</p> <p>If your dog does injure an animal, you should quickly contact a wildlife rescue organisation or take the animal to a veterinary practice or sanctuary. For small animals, even minor injuries from a dog will usually require veterinary attention.</p> <p>It’s our responsibility to be respectful visitors when we’re out in nature, and to make sure our dogs are too. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/214722/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/melissa-starling-461103"><em>Melissa Starling</em></a><em>, Postdoctoral Researcher in Veterinary Science, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Good news for weekend warriors: people who do much of their exercise on a couple of days still get heart benefits

<p><em><a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/raaj-kishore-biswas-1374060">Raaj Kishore Biswas</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Physical activity has <a href="https://bjsm.bmj.com/content/54/24/1451">established benefits</a> for health. The <a href="https://bjsm.bmj.com/content/54/24/1451">World Health Organization</a> recommends adults do a minimum of 150–300 minutes of moderate or 75–150 minutes of vigorous activity each week. This can include active transport from place-to-place, exercise for fun and fitness, energetic housework or physical activity at work.</p> <p>These amounts can be accrued by being, as the <a href="https://bjsm.bmj.com/content/54/24/1451">WHO recommends</a>, regularly active throughout the week, or being a “weekend warrior” who does the bulk of their activity on one to two days only, which don’t need to be consecutive.</p> <p>So far, experts haven’t fully established which of the two patterns is better for overall health. For many people, busy lifestyles may make it hard to be physically active every day. It may be more feasible to squeeze most physical activity and exercise into a few days.</p> <p>Fresh <a href="https://jamanetwork.com/journals/jama/fullarticle/2807286">analysis</a> of the large <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a> database attempted to compare these two patterns of weekly activity and compare how they reduced cardiovascular risk for heart attacks, heart failure, irregular heart beat and stroke.</p> <h2>What the new study found</h2> <p>Researchers analysed records from 89,573 participants who wore a wrist activity tracker for seven days and were tracked for cardiovascular events for over six years.</p> <p>Those who did less than the WHO recommended 150 minutes of moderate-to-vigorous physical activity per week were considered inactive. About a third (33.7%) of participants were inactive. Some 42.2% were termed active “weekend warriors” (they did at least 150 minutes and more than half of it occurred within one to two days) and 24% were regularly active (at least 150 minutes with most activity spread out over three or more days).</p> <p>Researchers considered the potential factors that could explain the link between physical activity and new cases of cardiovascular events, such as smoking and alcohol intake. They found both active groups showed similarly lower risk of heart attack (a 27% reduction for weekend warriors and 35% for regularly active people, compared with inactive participants).</p> <p>For heart failure, weekend warriors had a 38% lower risk than inactive people, while regular exercisers had a 36% lower risk. Irregular heartbeat risk was 22% lower for weekend warriors and 19% lower for regularly actively people. Stroke was 21% and 17% lower for weekend warriors and regular exercisers, respectively.</p> <h2>Not so fast. Some study limitations</h2> <p>Although the information was recorded by activity trackers, researchers did not consider on which days of the week the activity was done. Some people may have been active on Saturdays and Sundays, others might have chosen Wednesday and Friday – or different days each week. In that sense, <a href="https://jamanetwork.com/journals/jama/fullarticle/2807286">the study</a> examined a “pseudo-weekend warrior” pattern.</p> <p>Despite the many advantages the UK Biobank activity trackers have over <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">questionnaire-based studies</a>, these trackers are not great at capturing strength-training exercise, such as weights or pilates, and other static activities that have <a href="https://academic.oup.com/aje/article/187/5/1102/4582884">established cardiovascular</a> health benefits.</p> <h2>What other research in this area says</h2> <p>There have been several questionnaire based studies in this area in <a href="https://academic.oup.com/aje/article/160/7/636/136697">the past 20 years</a>.</p> <p>Our <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">2017 study</a>, for example, combined data from 63,591 adults from England and Scotland and tracked them over 12 years. We looked at <a href="https://theconversation.com/weekend-warrior-exercise-is-it-good-for-you-70964">risk reductions</a> for death from any cause, cardiovascular disease and cancer causes. We found similar benefits among people who clocked at least 150 minutes of moderate-intensity physical activity or at least 75 minutes of vigorous-intensity physical activity in one to two sessions per week, compared with three sessions or more per week.</p> <p>Our more <a href="https://www.nature.com/articles/s41591-022-02100-x">recent studies</a> used activity trackers and emphasised the flexibility of activity patterns that benefit the heart and circulation. We found doing short one-minute-long bouts of incidental vigorous physical activity three to four times a day can cut the risk of death from cardiovascular causes by <a href="https://www.nature.com/articles/s41591-022-02100-x">almost half</a>.</p> <p>Similarly, in another study we found just 19 minutes of vigorous physical activity a week was associated with <a href="https://academic.oup.com/eurheartj/article/43/46/4801/6771381">40% reduction</a> in the risk of cardiovascular death, with steadily increasing benefits to the maximum amount of vigorous activity recorded (110 minutes a week linked to a 75% risk reduction).</p> <h2>What it means for you and your routine</h2> <p>Taken together, the <a href="https://jamanetwork.com/journals/jama/fullarticle/2807286">new study</a> and <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">previous research</a> suggest the same thing: if it is difficult to find time to be active during a busy week, it is good enough to plan moderate to vigorous physical activities in a couple of weekdays or in the weekend.</p> <p>That said, there are benefits in being regularly physically active on most days of the week. A good session of aerobic exercise, for example, improves health indicators such as <a href="https://www.ahajournals.org/doi/full/10.1161/HYP.0000000000000196">blood pressure</a>, and <a href="https://link.springer.com/article/10.1007/s40279-021-01473-2">blood glucose</a> and <a href="https://lipidworld.biomedcentral.com/articles/10.1186/s12944-017-0515-5">cholesterol levels</a> for a day or longer. Such effects can moderate some of the long-term health risks of these factors and assist with their day-to-day management.</p> <p>But confirmation that we can be flexible about how physical activity is accumulated across the week for heart health benefits is encouraging. It offers more opportunities for more people to be active when it is convenient and practical for them.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210053/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, Professor of Physical Activity, Lifestyle, and Population Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, Postdoctoral Research Fellow, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/raaj-kishore-biswas-1374060">Raaj Kishore Biswas</a>, Research Fellow & Biostatistician, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Bindi Irwin breaks down on camera about health condition

<p>Bindi Irwin has shown her vulnerable side in an emotional new video shared with fans about a personal ordeal.</p> <p>The 24-year-old spoke candidly to the camera for 15 minutes with guest appearances from husband Chandler Powell and their daughter Grace Warrior.</p> <p>In the video, Irwin recalled the “insurmountable” pain she experienced due to endometriosis before finally <a href="https://www.oversixty.co.nz/health/caring/how-did-you-live-with-this-much-pain-bindi-irwin-hospitalised" target="_blank" rel="noopener">undergoing surgery</a>.</p> <p>The wildlife warrior announced her diagnosis in March 2023, but the new video explains her symptoms - which started when she was just 14 - that left her with “extreme fatigue, nausea and pain”.</p> <p>“I had pain every single day of my life. No matter where we went, where we were going, I would be falling asleep. I felt like I constantly had the flu,” she said.</p> <p>The conservationist confessed she tried everything to solve the issue, undergoing CT scans, MRIs and ultrasounds.</p> <p>“I was always in pain. We tried for a year, and finally a doctor told me it was just part of being a woman.”</p> <p>Irwin said it was that comment from a doctor that led her to suffer in silence.</p> <p>However, after giving birth to her daughter in 2021, the pain “magnified” to a point where it was “out of this world”.</p> <p>“I remember countless times of Grace needing me, and me crawling to her cot at night,” she revealed, becoming emotional.</p> <p>“I can remember being with Grace and lying on the floor in agony. I had a stabbing pain in my side, I couldn’t get up or I would throw up, and I was scared I would pass out.</p> <p>“I was so scared because I was worried if I was alone with Grace, something would happen to me, and she would be on her own.”</p> <p>Irwin dubbed the pain “insurmountable” and something that “would knock me over”.</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/Cr31hQDANTp/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/Cr31hQDANTp/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Bindi Irwin (@bindisueirwin)</a></p> </div> </blockquote> <p>She said that after returning to new doctors, she was diagnosed with irritable bowel syndrome and chronic fatigue.</p> <p>It was not until she spoke to a friend, Leslie Mosier, who recently had endometriosis surgery that she realised they shared similar symptoms.</p> <p>“Leslie said the only way to diagnose for sure is through exploratory surgery.”</p> <p>Irwin said she decided to undergo surgery in the US as her daughter would have Powell’s parents, who live in Florida, nearby for support while she recovered.</p> <p>At this point in her video, Grace woke up and joined her mum on camera.</p> <p>“Mama went for surgery and they found 37 lesions and a chocolate cyst on my ovary,” she said in a child-like tone for the sake of her daughter.</p> <p>“Ovary!” Grace chirped.</p> <p>“After surgery mama feels a lot better hey?

Doctors need the right tools to diagnose.”</p> <p>She explained that her own endometriosis has been classified as severe, which means she may have to undergo more surgeries in the future to keep symptoms at bay.</p> <p>“I feel like.

Six of the best wildlife cruise destinations

<p>Cruises allow nature lovers to get close to wildlife with small ships, unique itineraries and practical shore excursions. Here are six of the best places to see wildlife from the water.</p> <p><strong>Sea of Cortez, Mexico</strong></p> <p>Legendary oceanographer Jacques Cousteau called the Sea of Cortez, off the coast of Baja California, the aquarium of the world. Where the sea meets the Pacific Ocean tidal currents create an ideal environment for sea life and you’ll see everything from tiny fish right up to sperm whales. Watch huge Pacific manta rays leap out of the water or grab a snorkel and dive with playful sea lions. California gray whales are one of the biggest drawcards, coming to the region to calve during the winter, and you’ll have the opportunity to get up close in a Zodiac.</p> <p><strong>Galapagos Islands </strong></p> <p>There’s nowhere in the world like the Galapagos Islands, a volcanic archipelago around 1,000 kilometres off the coast of Ecuador in the Pacific Ocean. Look out for giant tortoises, iguanas, penguins, seals, sea lions and a spectacular array of birds, including the dancing blue-footed booby, albatross, pelican, heron and egret. Charles Darwin visited the islands in 1835 and developed much of his evolutionary theory based on the adaptations of Galapagos bird species, especially finches.</p> <p><strong>Alaska</strong></p> <p>America’s 50<sup>th</sup> state is a true wilderness with wildlife to be seen in the ocean, on the land and in the air. Humpback and killer whales, dolphins, porpoises, seals, sea lions, otters and leaping salmon can be found in the water, seen either from the main cruise ship or on Zodiac excursions. Grizzly bears wander the shore alongside caribou, moose, beavers and even wolverines. The American national bird, the bald eagle, is a regular in the sky with a population of more than 30,000 – in fishing towns like Ketchikan you’ll even see them swooping around the docks for fish.</p> <p><strong>Antarctica</strong></p> <p>Penguins, penguins, penguins. From the cute little rockhopper penguins in the sub-Antarctic islands to the huge, 1.15 metre tall emperor penguins in continental Antarctica, not a day will go by on a cruise here that you don’t see a penguin. If you get penguined out, there are also killer and sperm whales, elephant seals, leopard seals and a huge number of sea birds like albatross, petrels and skuas. For a close encounter, jump in a kayak and paddle amongst the wildlife in the freezing waters.</p> <p><strong>Southern Africa</strong></p> <p>This is a safari with a difference. Small river ships cruise along the Chobe River through Botswana and Namibia carrying just a handful of passengers. The river runs through the Chobe National Park, which has one of the highest concentrations of wildlife in Africa. Elephants and buffalo can be seen right from the decks, splashing along the edges of the river just metres from the ship. Cruises here include early morning game drives that take passengers further into the national park to see lions, giraffe, leopards, antelope and plenty of birds.</p> <p><strong>Peruvian Amazon</strong></p> <p>Think dolphins only come in gray? Think again. A very rare breed of pink freshwater dolphin swims in the waters of the Amazon River, one of only a couple of places in the world that they can be seen. Small, specially designed river ships sail along the Peruvian section of the river where squirrel monkeys swing through the trees, sloths laze about in the branches and brightly coloured macaws squawk from the canopy. Passengers even have a chance to catch and eat the flesh-eating piranha.</p> <p><em>Images: Getty</em></p>

Only in Florida! Woman's shocking find lurking in backyard pool

<p dir="ltr">Florida woman Lynn Tosi was not the only one who wanted to stay cool during the summer.</p> <p dir="ltr">Tosi came home to an unwanted guest: a 3.5 m alligator that had busted through her screened-in porch and was vibing in her pool.</p> <p dir="ltr">“I just kind of circled around, not knowing what I was going to do next. I sure wasn’t going outside,” Tossi said.</p> <p dir="ltr">The crook-a-dile waddled through a nearby forest to try and find water, and struck gold when he found Tossi’s pool.</p> <p dir="ltr">Without a care in the world, the insti-gator left a large hole in Tosi’s screened-in porch.</p> <p dir="ltr">“He busted right through there, kind of like the Kool-Aid man, you know,” Tosi shared.</p> <p dir="ltr">As the weather gets warmer, Alligators are becoming increasingly active, and Tosi, who has learned from this wild encounter, encouraged all homeowners to double-check their pools and lakes before diving in.</p> <p dir="ltr">“The professional coming to take him out was actually pacing and got on the phone and was really surprised by what they were up against,” Tosi recalled.</p> <p dir="ltr">In another image, the Alligator can be seen restrained, and they were lucky it didn’t snap.</p> <p dir="ltr">This encounter is one of three reported in Valusia County over the last five days.</p> <p dir="ltr">Trappers have reminded residents that the alligators are most active at dusk and dawn.</p> <p dir="ltr"><em>Image: Lynn Tosi, NBC, CNN</em></p>

“You wouldn’t believe all I had to do to survive”: Man rescued after 31 days in the jungle

<p>A Bolivian man has survived 31 days in the Amazon jungle.</p> <p>Jhonattan Acosta, 30, was hunting in northern Bolivia when he was separated from his four friends.</p> <p>He told United TV he drank rainwater collected in his shoes and ate worms and insects while hiding from jaguars and peccaries, a type of pig-like mammal.</p> <p>Acosta was finally found by a search party made up of locals and friends a month after he went missing.</p> <p>“I can’t believe people kept up the search for so long,” he said in tears.</p> <p>“I ate worms, I ate insects, you wouldn’t believe all I had to do to survive all this time.”</p> <p>He also ate wild fruits similar to papayas, known locally as gargateas.</p> <p>“I thank God profusely, because he has given me a new life,” he said.</p> <p>His family said they will still have to string all the details together regarding how Acosta got lost and how he managed to stay alive but will ask him gradually as he is still psychologically damaged after the experience.</p> <p>There has also been significant physical changes. Acosta lost 17kg, dislocated his ankle and was severely dehydrated when he was found, but according to those who found him, he was still able to walk with a limp.</p> <p>“My brother told us that when he dislocated his ankle on the fourth day, he started fearing for his life,” Horacio Acosta told Bolivia’s Página Siete newspaper.</p> <p>“He only had one cartridge in his shotgun and couldn’t walk, and he thought no one would be looking for him anymore.”</p> <p>As for his encounters with wild animals in the jungle, including a jaguar, his younger brother said that his brother used his last cartridge to scare off a squadron of peccaries.</p> <p>After 31 days, Acosta spotted the search party about 300m away and limped through thorny bushes, shouting to draw attention to him.</p> <p>Acosta’s brother, Haracio, said that he was found by four local people.</p> <p>“A man came running to tell us they’d found my brother,” he said. “It’s a miracle.”</p> <p>Acosta has since decided to give up hunting for good.</p> <p>“He is going to play music to praise God,” Haracio said. “He promised God that, and I think he will keep his promise.”</p> <p><em>Image credit: BBC News</em></p>

Take a walk on the wild side with the Wildlife Photographer of the Year awards

<p>The People’s Choice Award winners of the 2022 Wildlife Photographer of the Year awards have been revealed, featuring stunning images of some of the world’s most majestic creatures. </p> <p>Competition for the coveted People’s Choice Award was fierce, with over 39,000 images submitted for consideration. 25 pictures were shortlisted from there, and a staggering 60,466 votes were received to crown the winner: German photographer Sascha Fonseca. </p> <p>Sascha’s image, titled “World of the snow leopard”, presents a snow leopard at sunset in Ladakh in northern India, with a breathtaking snow-covered mountain range backdrop. </p> <p>“Thick snow blankets the ground, but the big cat’s dense coat and furry footpads keep it warm,” the image was captioned. “Sascha captured this image during a three-year bait-free camera-trap project high up in the Indian Himalayas. He has always been fascinated by snow leopards, not only because of their incredible stealth but also because of their remote environment, making them one of the most difficult large cats to photograph in the wild.”</p> <p>The winning images, selected for their “artistic composition, technical innovation, and truthful interpretation of the natural world”, boast not only a winner, but four other highly commended finalists as well. </p> <p>"This year’s record number of votes illustrates how wildlife photography can engage and inspire audiences with the wonder of nature,” said Director of the Natural History Museum Douglas Gurr.</p> <p>The other finalist feature a leopard with some unexpected cargo titled “Holding on” by Igor Altuna, a moment of “Fox affection” in the snow by Brittany Crossman, a polar bear basking in the sun “Among the flowers” by Martin Gregus, and a magnificent “Portrait of Olobor” the lion by Maasai Mara. </p> <p>The Wildlife Photographer of the Year competition, produced by the Natural History Museum, provides amateur and professional photographers from around the world with a global platform for their work. 2022 marked the 58th year of competition, and the 59th is currently being judged, with the 2023 winners to be announced in October. </p> <p><em>All image credits: Wildlife Photographer of the Year awards</em></p>

Hilarious winners of the worldwide 2022 Comedy Wildlife Photography Awards

<p>The winners of the 2022 Comedy Wildlife Photography Awards have been announced, with some hilarious photos capturing astounding moments of the most adorable animals. </p> <p>An image of a three-month-old lion cub falling out of a tree has been named the overall winner of this year's competition, with Jennifer Hadley in the Serengeti, Tanzania, capturing the moment late one afternoon. </p> <p>"It didn't even occur to me that he would make a go of getting down by himself in the most un-cat like fashion. I mean, how often do cats fall out of trees?" Hadley said in a press release.</p> <p>"No one expected this to happen and of course we were concerned for his safety but happily as cats do, he righted himself just in time and landed on all fours and ran off with his siblings. A happy ending for a hapless kitty who didn't quite know how to get down from a tree." </p> <p>Hadley also won the People's Choice Award for her photo of a dismissive penguin seemingly snubbing his friend, which was titled <em>Talk to the Fin</em>. </p> <p><em>All image credits: Comedy Wildlife Photography Awards 2022</em></p>

Australia Zoo insider claims Bindi Irwin never wanted to follow her father's footsteps

<p>An insider at Australia Zoo has claimed that Bindi Irwin never wanted to follow in the footsteps of her late father. </p> <p>Justin Lyons, a cameraman who was there the day Steve Irwin died from a stingray attack in 2006, said in a recent interview that Australia Zoo is almost "cult-like" with Steve's imagery looming everywhere, reminding him of the day the original wildlife warrior died. </p> <p>Among his stunning revelations, he claims the now 24-year-old Bindi initially "didn't really want" to follow in her famous dad's footsteps.</p> <p>"Bindi and I spent a lot of time together," Justin told <a href="https://www.nowtolove.com.au/celebrity/celeb-news/bindi-irwin-carries-on-steve-legacy-75512" target="_blank" rel="noopener">Woman's Day</a>. "We'd go up to Far North Queensland and while they were doing whatever, Bindi and I would go off. She'd say to me, 'I don't really like bugs', but she was expected to do all this crazy stuff."</p> <p>The allegations are a far cry from Bindi's own words, given that in 2018 she told Insider, "Ever since I can remember, I've always said, 'When I grow up, I want to be just like Dad.'"</p> <p>However, some sources close to the Irwin family say there "may be a layer of truth" to Justin's comments. </p> <p>"She couldn't have predicted it back when she was a little kid wandering around the bush with Justin, but the reality is Bindi is in a tough position," says an insider. </p> <p>"She was a big star for a time in America and for a while it looked like she was set to break the big time in Hollywood, but now she's back at the zoo learning the ropes to take over when her mother retires, and as it is currently, its glory days are long over."</p> <p>The insider claimed Bindi feels torn between two worlds, as she strives to make her parents proud with her ongoing work at Australia Zoo, but also the pull back to the US, where she has the potential to make a name for herself in her husband Chandler Powell's home country.</p> <p>"Bindi and Chandler have often toyed with the idea of moving to the States, especially now they have baby Grace, and they've barely seen Chandler's parents in recent years," says a source.</p> <p>"But Bindi feels tied to the zoo, whether she wants to be or not."</p> <p><em>Image credits: Getty Images</em></p>

Bindi Irwin's daughter Grace looks just like her famous Irwin relatives

Three men handed jail sentences after careless, drunken act in a national park

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&q=45&auto=format&w=754&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&q=45&auto=format&w=754&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&q=45&auto=format&w=754&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.

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.

Experience the spectacular sounds of a Murrumbidgee wetland erupting with life as water returns

<p>In the southwestern corner of New South Wales, along the Murrumbidgee river, frogs are calling in a wetland called Nap Nap. This is <a href="https://www.narinari.org/our-journey">Nari Nari</a> country – nap nap means “very swampy” in traditional language.</p> <p>Nap Nap is one of many inland wetlands across Australia to receive so-called “environmental water”: water allocated and managed to improve the health of rivers, wetlands and floodplains.</p> <p><a href="https://flow-mer.org.au/">Long-term monitoring</a> shows how these environmental flows sustain big old trees and cycle nutrients through the ecosystem. They drive breeding for frogs, waterbirds, reptiles and fish, and protect endangered species. This is a good news story for our inland waterways – but it’s mostly told through scientific reports.</p> <p>We wanted to use ecological data to convey not just facts but feelings, and create a vivid digital portrait of life in Nap Nap. So we recently produced <a href="https://flow-mer.org.au/napnap/">The Sound of Water</a>, using audio, images and water data to reveal the patterns and rhythms of the swamp.</p> <p>In part, this is about finding an engaging way to tell an important story. But there’s a bigger agenda here too: how might we use environmental data to amplify humanity’s attachment to the living world?</p> <p><a href="https://images.theconversation.com/files/439776/original/file-20220107-13-1wm9dil.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/439776/original/file-20220107-13-1wm9dil.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="A view of a forest wetland, with water surrounded by tall gum trees" /></a> <span class="caption">Nap Nap wetland, the name of which means ‘very swampy’ in traditional language.</span> <span class="attribution"><span class="source">Gayleen Bourke</span></span></p> <h2>Addressing an imbalance</h2> <p>Healthy wetlands rely on varying river flows. When a river is flooding or at high flow, water is delivered to wetlands, enabling seeds to sprout and animals to move and breed. When the river is at low flow, wetlands enter a natural drying phase.</p> <p>But across Australia, thousands of wetlands have lost their natural connection to rivers. Lower river flows – the result of water regulation and diversions required to meet human needs – means many wetlands no longer experience these natural cycles.</p> <p>Environmental flows seek to address this imbalance. Managed by water authorities, the flows involve strategically delivering water to replenish rivers, wetlands and floodplains.</p> <p>Our project – a design-science collaboration – was funded by the Commonwealth Environmental Water Office’s <a href="https://flow-mer.org.au">Flow-MER program</a>, which undertakes long-term monitoring of the ecological impact of environmental water allocations.</p> <h2>The Sound of Water</h2> <p>Across nine days in spring of 2020, an environmental flow of about 16,000 million litres rolled into Nap Nap swamp in the Lowbidgee floodplain after a brief dry spell. The Lowbidgee floodplain is near the confluence of the Kalari (Lachlan) and Murrumbidgee rivers in New South Wales.</p> <p>The frogs began calling as the water returned. But don’t take our word for it - <a href="https://theconversation.com/experience-the-spectacular-sounds-of-a-murrumbidgee-wetland-erupting-with-life-as-water-returns-174423">listen for yourself.</a></p> <p>In this clip, you can hear the squelchy, “cree-cree” call of tiny, hardy Murray Valley froglets. You can also hear inland banjo frogs, whose “dok” call sounds a bit like a plucked string; spotted marsh frogs with a machine-gun like “duk-duk-duk”; and the shrill, rattling call of Peron’s tree frog.</p> <p>This recording comes from an audio logger used in Flow-MER’s environmental monitoring. These automatic devices record for five minutes every hour, day and night – that’s two hours of sound captured every day.</p> <p><img src="https://images.theconversation.com/files/440161/original/file-20220111-17-5maxbu.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="A small light grey frog on a tree branch calling, with its throat puffed out" /> <span class="caption">The Peron’s tree frog has a shrill, rattling call.</span> <span class="attribution"><span class="source">Damian Michael</span></span></p> <h2>Seeing wetland sounds</h2> <p>To reveal the content of all this audio, we used a visual representation of sound known as a spectrogram. We adapted a <a href="https://doi.org/10.1016/j.procs.2014.05.063">technique</a> developed by researchers at the Queensland University of Technology which enables ecologists to visualise and analyse thousands of hours of recordings.</p> <p>We visualised almost a year’s worth of audio from Nap Nap – more than 700 hours.</p> <p>The below image contains spectrograms of audio from June 2020, which was a dry period in the swamp. The colourful central band corresponds to the noisy daylight hours, when woodland birds dominate.</p> <p>The vivid blue areas are wind and rain noise. The pink and orange are mostly bird calls, and continuous sounds like cricket calls show up as strong horizontal bands (top right).</p> <p>The mostly dark outer bands correspond to the nights, which in dry periods are fairly quiet.</p> <p><a href="https://images.theconversation.com/files/439614/original/file-20220106-19-77zfci.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/439614/original/file-20220106-19-77zfci.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Spectrograms of audio showing the patterns and variation of activity across 10 days" /></a> <span class="caption">Spectrograms of Nap Nap audio from June 2020.

Our story focuses on this moment. We found a way to link the visuals to the source audio, creating interactive timelines in which we can see, hear and explore the wetland soundscape.</p> <p>The stars of our story are Nap Nap’s frogs, and our most important find was a southern bell frog. Once widespread across southeastern Australia, these frogs are now found in only a few isolated populations.</p> <p>Their distinctive call indicates the ecological health of Nap Nap, and the value of these environmental flows.

It works because it’s familiar (everyone can scroll) and translates well to all kinds of devices.

Hitting the beach this summer? Here are some of our top animal picks to look out for

<p>Australia has one of the longest coastlines in the world.

The large <a href="https://australian.museum/learn/animals/mammals/bottlenose-dolphin/">bottlenose dolphins</a> (<em>Tursiops spp.</em>) are relatively common and can be spotted all the way around our coast.</p> <p>You might see them playing in the waves, jumping out of the water, or even surfing among humans.</p> <p><a href="https://images.theconversation.com/files/436606/original/file-20211209-133881-1px5omu.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/436606/original/file-20211209-133881-1px5omu.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Bottlenose dolphin mother and cals" /></a> <span class="caption">Bottlenose dolphins are generally grey with a lighter underside and have a pronounced, curved dorsal (upper) fin.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <p>Turtles are less obvious, but can be spotted as they bob their heads out of the water to breathe.

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&q=45&auto=format&w=754&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.

Of all sharks occurring in Australian waters, 70% were assessed as “Least Concern”.</p> <p>But we identified 39 Australian shark species threatened with extinction. And worryingly, most lack the protection or conservation plans needed for their populations to recover.</p> <p>For example, only nine of the species are listed as threatened under Australia’s federal environment law, the Environment Protection and Biodiversity Conservation Act.</p> <p>We identified five species where the data is robust enough to pass the threatened species nomination process, and recommend federal authorities consider these species for immediate listing. 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>. However, nominations to be listed as threatened under federal law will require more data, particularly contemporary catch levels and trends.</p> <p>As with many other species we identified, there is currently no mechanism – or dedicated funding – in place to ensure such data is collected.</p> <p><img src="https://images.theconversation.com/files/436576/original/file-20211209-27-1bianty.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="A small shark" /> <span class="caption">Colclough’s Shark, a rare threatened shark at risk of falling through the cracks.</span> <span class="attribution"><span class="source">Nigel Marsh</span></span></p> <h2>How to save Australian sharks</h2> <p>Major investment is needed to recover Australia’s threatened sharks.

Such a fund should support the recovery planning process – in contrast to current federal government moves to scrap recovery plans for nearly <a href="https://www.theguardian.com/environment/2021/sep/18/coalition-plans-to-scrap-recovery-plans-for-200-endangered-species-and-habitats">200 threatened species</a>.</p> <p>Our research is a call to action to secure all Australia’s sharks.

1 millipede, 1,306 legs: we just discovered the world’s leggiest animal hiding in Western Australia

<p>Millipedes were the first land animals, and today we know of more than 13,000 species. There are likely thousands more species of the many-legged invertebrates awaiting discovery and formal scientific description.</p> <p>The name “millipede” comes from the Latin for “thousand feet”, but until now no known species had more than 750 legs. However, my colleagues and I recently found <a href="https://www.nature.com/articles/s41598-021-02447-0">a new champion</a>.</p> <p>The eyeless, subterranean <em>Eumillipes persephone</em>, discovered 60 metres underground near the south coast of Western Australia, has up to 1,306 legs, making it the first “true millipede” and the leggiest animal on Earth.</p> <h2>Finding life underground</h2> <p>In Australia, most species in some groups of invertebrates are still undescribed. Many could even become extinct before we know about them.</p> <p>Part of the reason is that life is everywhere, even where we least expect it. You could be excused for thinking remote areas of Western Australia such as the Pilbara and the Goldfields, where the land is arid and harsh, are not home to too many species.</p> <p><img src="https://images.theconversation.com/files/437949/original/file-20211216-15-11fkzif.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /> <span class="caption">The arid landscapes of Western Australia harbour a surprising diversity of life.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <p>But the reality is very different. An enormously diverse array of poorly known animals live underground, inhabiting cavities and fractures in the rock several metres below the surface.</p> <p>One way to find out about these creatures is to place “troglofauna traps” far below the surface. <em>E. persephone</em> was found in one of these traps, which had spent two months 60m underground in a mining exploration bore in the Goldfields.</p> <h2>A lucky discovery</h2> <p>At the time I was working for a company called Bennelongia Environmental Consultants, which had been hired by the mining company to survey the animals in the area. I was lucky enough to be in the laboratory on the day the leggiest animal on Earth was first seen.</p> <p>Our senior taxonomist, Jane McRae, showed me these incredibly elongated millipedes, less than a millimetre wide and almost 10 centimetres long. She pointed out how their triangular faces placed them in the family Siphonotidae, comprised of sucking millipedes from the order Polyzoniida.</p> <p><a href="https://images.theconversation.com/files/437938/original/file-20211216-21-3yvudt.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/437938/original/file-20211216-21-3yvudt.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /></a> <span class="caption">A female <em>Eumillipes persephone</em> with 330 segments and 1,306 legs.</span> <span class="attribution"><span class="source">Paul E. Marek, Bruno A. Buzatto, William A. Shear, Jackson C. Means, Dennis G. Black, Mark S. Harvey, Juanita Rodriguez, Scientific Reports</span>, <span class="license">Author provided</span></span></p> <p>Their long, thin and pale bodies, with hundreds of legs, reminded me of a paper I had read years earlier, which redescribed the leggiest millipede in the world, the Californian <em>Illacme plenipes</em>, bearing 750 legs. Back in 2007, while teaching zoology at Campinas State University in Brazil, I used that paper to explain to students how no millipede species in the world really had 1,000 legs.</p> <p>Often, popular names are scientifically inaccurate, but in front of me I had an animal that stood a chance of finally making the name millipede biologically correct.</p> <h2>A true millipede at last</h2> <p>I suggested to Jane that our new specimens might be more consistent with <em>I. plenipes</em>, which belongs to another order of millipedes, the Siphonophorida. We consulted Mark Harvey from the WA Museum, and together were surprised to realise Siphonophorida are very rare in Australia: there are only three known species, all found on the east coast.</p> <p>Next, I contacted Paul Marek at Virginia Tech in the United States, a millipede expert and lead author of that paper about the 750-legged <em>I. plenipes</em>. He was excited to receive the specimens a few weeks later.</p> <p>This new species turned out to have up to 1,306 legs, making it the first true millipede. Paul named it <em>Eumillipes persephone</em>, in reference to its “true 1,000 legs” nature, and to Persephone, the goddess of the underworld in Greek mythology who was taken from the surface by Hades.</p> <h2>Why so many legs?</h2> <p><em>E. persephone</em> was most likely driven to its underground life as the landscape above became hotter and drier over millions of years. We eventually discovered Jane was right about the nature of <em>E. persephone</em>: it is in fact a member of the Siphonotidae family, only distantly related to <em>I. plenipes</em>, and is therefore the only species in the whole order Polyzoniida with no eyes.</p> <p>We classify any millipede with more than 180 body segments as “super-elongated”. <em>E. persephone</em> has 330.</p> <p><a href="https://images.theconversation.com/files/437943/original/file-20211216-15-zklige.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/437943/original/file-20211216-15-zklige.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /></a> <span class="caption">Just a few of the legs of a male <em>Eumillipes persephone</em>.</span> <span class="attribution"><span class="source">Paul E.

Harvey, Juanita Rodriguez, Scientific Reports</span>, <span class="license">Author provided</span></span></p> <p>With a genetic analysis, we found that super-elongation has evolved repeatedly in millipedes, and it might be an adaptation to living underground.</p> <p>The large number of legs likely provides enhanced traction and power to push their bodies through small gaps and fractures in the soil. But this is just a hypothesis at this stage, and we have no direct evidence that having more legs is an adaptation to subterranean life.</p> <h2>Finding the unknown</h2> <p>Finding this incredible species, which represents a unique branch of the millipede tree of life, is a small first step towards the conservation of subterranean biodiversity in arid landscapes.</p> <p>This starts with documenting new species, assessing their vulnerability, and ultimately devising conservation priorities and management plans.</p> <p>A large proportion of the species of arid Australia are undescribed. For subterranean fauna, this may be more than 90%. Not knowing these animals exist makes it impossible to assess their conservation status.</p> <p>Biodiversity surveys, and especially the taxonomy that supports them, are incredibly important. Taxonomists such as Jane, Paul and Mark are the unsung heroes of conservation.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/173753/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><span><a href="https://theconversation.com/profiles/bruno-alves-buzatto-185830">Bruno Alves Buzatto</a>, Principal Biologist at Bennelongia Environmental Consultants, <em><a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a></em></span></p> <p>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Shark bites are rare. Here are 8 things to avoid to make them even rarer

<p>Shark bite incidents are <a href="https://www.floridamuseum.ufl.edu/shark-attacks/odds/how-where-when/">rare</a> but traumatic. They’re usually followed by calls for <a href="https://affirmpress.com.au/publishing/sharks-a-history-of-fear-in-australia/">mitigation</a> <a href="https://www.int-res.com/abstracts/meps/v631/p165-179/">strategies</a>, some of which are dangerous or lethal to sharks – despite the fact most sharks are timid and actively <a href="https://www.researchgate.net/publication/266853603_Monitoring_the_effects_of_tourism_on_whale_shark_Rhincodon_typus_behaviour_in_Mozambique">avoid people</a>.</p> <p>The “<a href="https://www.daf.qld.gov.au/sharksmart">SharkSmart</a>” approach, adopted by the Queensland government, aims to educate and urge people to take responsibility for reducing the risk of shark bites by changing their own behaviour. But can humans change?</p> <p>To find out, we teamed up with three companies in the sailing charter industry in the Whitsundays area to better understand how people were using the environment, their knowledge of shark smart behaviours and to see if promoting SharkSmart behaviours led to change.</p> <p>We <a href="https://www.publications.qld.gov.au/dataset/queensland-shark-control-program/resource/27af7dc2-73c5-4752-81c0-d6c8374c92e1">found</a> people can and do change behaviour as a result of education – but for some, unfortunately, a “she’ll be right” attitude still prevails.</p> <p><a href="https://images.theconversation.com/files/381253/original/file-20210129-17-1tc89vl.jpg?ixlib=rb-1.1.0&rect=0%2C0%2C3159%2C2090&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/381253/original/file-20210129-17-1tc89vl.jpg?ixlib=rb-1.1.0&rect=0%2C0%2C3159%2C2090&q=45&auto=format&w=754&fit=clip" alt="Sharks swim in clear waters." /></a> <span class="caption">People must take responsibility for reducing the risk of shark bites by changing their own behaviour.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>Doing your part to be SharkSmart</h2> <p>Previous surveys had shown many water-users were already aware of many ways to reduce shark risk but there was <a href="https://www.australiangeographic.com.au/topics/wildlife/2018/10/experts-weigh-in-on-the-whitsundays-shark-encounters">room for improvement</a>.</p> <p>Many SharkSmart behaviours are well known, such as not swimming at dusk or dawn when sharks may be more prevalent.</p> <p>But we wanted to find out what else people were doing in the water and see if some key SharkSmart interventions made a difference. The interventions included:</p> <ul> <li>showing people a short <a href="https://www.youtube.com/watch?v=d17id9NOR6s&feature=youtu.be">video</a> before they went out on the water</li> <li>putting stickers on boats to remind people how to reduce shark risk</li> <li>making SharkSmart brochures available to guests on boats</li> <li>dedicated waste disposal bags were given to two of the charter boat operators, with the third acting as a control group.</li> </ul> <p><iframe width="440" height="260" src="https://www.youtube.com/embed/d17id9NOR6s?wmode=transparent&start=0" frameborder="0" allowfullscreen=""></iframe></p> <p>We did surveys before and after these SharkSmart tools were introduced to see what changed.</p> <p>We particularly wanted to know whether people were less likely to do eight things linked to higher shark risk in the Whitsundays area:</p> <p><strong>1. splashing in the water</strong></p> <p><strong>2. swimming alone</strong></p> <p><strong>3. swimming near fishers</strong></p> <p><strong>4. swimming at spots where shark bites have occurred in the past (in this case, in <a href="https://www.daf.qld.gov.au/business-priorities/fisheries/shark-control-program/whitsundays-plan">Cid Harbour</a>)</strong></p> <p><strong>5. throwing fish scraps in the water</strong></p> <p><strong>6. throwing burley (a type of bait, sometimes known as chum) in the water</strong></p> <p><strong>7. fishing near swimmers</strong></p> <p><strong>8. throwing food in the water.</strong></p> <p><a href="https://www.publications.qld.gov.au/dataset/queensland-shark-control-program/resource/27af7dc2-73c5-4752-81c0-d6c8374c92e1">Research</a> suggests that by <em>not</em> doing these eight things, we can make shark bites even rarer than they already are.</p> <p>As well as the before-and-after surveys, we captured a sample of rubbish coming back on shore. This was so we could get an idea of whether fish and meat were being stored or thrown overboard.</p> <p>We also wanted to see <em>where</em> and <em>when</em> risk might be higher. For example, snorkelling in a busy anchorage or where people are fishing may increase unnecessary dangers. The warmer months of September to December were mapped as potential higher risk for shark bites.</p> <h2>Our findings</h2> <p>We surveyed 228 tourists (92 pre- and 136 post-intervention) and found:</p> <ul> <li>a 8.9% reduction in splashing or making noise when swimming or snorkelling</li> <li>a 4.1% reduction in throwing fish scraps overboard and</li> <li>a 3.8% reduction in people fishing near people swimming.</li> </ul> <p><a href="https://images.theconversation.com/files/381250/original/file-20210129-23-462790.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/381250/original/file-20210129-23-462790.png?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" alt="A poster shows SharkSmart behaviours." /></a> <span class="caption">A poster shows SharkSmart behaviours.</span> <span class="attribution"><span class="source">Queensland Government</span>, <span class="license">Author provided</span></span></p> <p>We found most people were aware of these six behaviours:</p> <ul> <li>following local signage</li> <li>having a buddy when swimming, diving or snorkelling</li> <li>avoiding swimming at dawn or dusk</li> <li>swimming in clear water</li> <li>keeping fish waste and food scraps out of the water where people swim</li> <li>avoiding swimming with schools of bait fish or diving birds.</li> </ul> <p>The lowest awareness was for the last one, but after our intervention we saw a 4.7% increase in knowledge of this behaviour.</p> <p>Although 100% of people were aware of the need to keep fish waste and food scraps out of the water, our pre-surveys between August and October last year found about one-third of tourists still disposed of fish scraps into the water. After the intervention, the share of people doing this dropped to 4-8%.</p> <h2>Shifting the ‘she’ll be right’ attitude</h2> <p>The good news is there is very high awareness of SharkSmart behaviours and most times, people didn’t throw burley in the water, fish near swimmers or swim in Cid Harbour.</p> <p>Unfortunately, some people continued to splash, swim alone and throw fish waste and food scraps in the water. Changing these norms among swimmers and boaties will take time.</p> <p>An attitude of “she’ll be right” still exists among some water users and this group may be the toughest to influence; it’s hard to shift attitudes about dangers among people with such a relaxed attitude to risk.</p> <p>In the Whitsundays and wider Australia, we are lucky to have some of the most incredible beaches, islands and reefs in the world. Most of us are willing to take a small calculated risk to swim in the ocean. Shark bite incidents are <a href="https://taronga.org.au/conservation-and-science/australian-shark-attack-file">extremely rare in Australia</a> but by making small changes, we can drive down the danger even further.</p> <p><em>Katie Frisch and Gemma Molinaro from Reef Ecologic contributed to this article.</em><img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/173746/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><span><a href="https://theconversation.com/profiles/adam-smith-515741">Adam Smith</a>, Adjunct Associate Professor, <em><a href="https://theconversation.com/institutions/james-cook-university-1167">James Cook University</a></em></span></p> <p>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Trouble

Nature is hiding in every nook of Australia’s cities – just look a little closer and you’ll find it

<p>Thanks to technological advances, citizen science has experienced unprecedented global growth over the past decade. It’s enabled millions of people to get involved in science, whether by gathering data, sharing health information or helping to map galaxies.</p> <p>And just because you live in a city, it doesn’t mean you can’t observe, learn about and contribute to scientific understanding of the natural world. Sometimes, it just means looking a little closer.</p> <p>However, <a href="https://link.springer.com/article/10.1007%2Fs11252-021-01187-3">our recent study</a> revealed in Australia, the number and diversity of urban ecology citizen science projects is relatively low.</p> <p>This is despite cities being important places of conservation and discovery. There’s enormous value in citizen science projects that encourage urbanites to learn about what is often, quite literally, on their doorsteps.</p> <p><img src="https://images.theconversation.com/files/436266/original/file-20211208-25-4348qs.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Two woman tag butterfly" /> <span class="caption">Urban citizen scientists are a valuable, untapped resource in Australia.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>Cities are important for conservation</h2> <p>Recent COVID-19 restrictions mean many of us became more intimately connected to the environment around us. But there is still an overriding <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13193">perception</a> of urban areas as wastelands devoid of rich and diverse species.</p> <p>It’s true that for many centuries, vegetation in urban areas has been removed to make way for buildings, roads and other human structures. In many cases, this had led to a more homogeneous composition of species and, in Australia’s case, a seeming predominance of introduced plant and animal species.</p> <p>However, recent <a href="https://doi.org/10.1002/fee.2032">literature</a> has shown cities remain vital habitats for many native species. This includes threatened species such as the <a href="https://onlinelibrary.wiley.com/doi/10.1111/geb.12404">fringed spider orchid</a>, found only in Greater Melbourne.</p> <p>Recent research <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2032">found</a> 39 nationally threatened species live only in Australian cities and towns, including the western swamp tortoise in Perth and the angle-stemmed myrtle in Brisbane.</p> <p>It’s important to preserve native vegetation remnants in towns and cities, as well as traditional urban green spaces like parks, cemeteries and backyards.</p> <p>But it’s just as important to understand which species call these areas home and why. That’s where citizen science can play a big role.</p> <p><img src="https://images.theconversation.com/files/436280/original/file-20211208-188518-bgx9vh.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="white flower and leaves" /> <span class="caption">The angle-stemmed myrtle is found only in Brisbane.</span> <span class="attribution"><span class="source">Logan City Council</span></span></p> <h2>What we found</h2> <p>We set out to examine the extent to which urban ecology projects in Australia harnessed the resources of citizen scientists. We did this by analysing the projects <a href="https://biocollect.ala.org.au/acsa#isCitizenScience%3Dtrue%26isWorldWide%3Dfalse%26max%3D20%26sort%3DnameSort">listed</a> in the Citizen Science Project Finder, hosted by the Atlas of Living Australia.</p> <p>Of 458 active citizen science projects, only 19 (or 5.3%) were focused on urban environments. Given the number of urban residents in Australia, this constitutes a significant under-representation of projects tailored for these people.</p> <p>Most of the 19 projects focused on four major cities – Sydney, Brisbane, Perth and Adelaide – while other major cities were notably omitted.</p> <p>Eight projects focused on broad census approaches – essentially ad hoc observations focused on birds or all flora and fauna in a region. Documenting the presence of various species in urban areas is important. But there’s potential for citizen scientists to help answer more targeted research questions.</p> <p>For example, grey-headed flying foxes have been <a href="https://zslpublications.onlinelibrary.wiley.com/doi/10.1111/j.1469-7998.2005.00005.x">documented</a> re-colonising habitat in Melbourne they were once absent from. As cities continue to grow, knowing which species can persist and which have been pushed out is incredibly valuable – and citizen scientists can help in this task.</p> <p>Also, many of the 19 projects did not provide an easy way to participate, such as easy links to platforms to record and upload data. We were also unable to find scientific papers where results from any of the 19 projects had been published.</p> <p>Publications would further strengthen the validity of a citizen science approach in urban environments and add another way to measure success.</p> <p><img src="https://images.theconversation.com/files/436277/original/file-20211208-141979-1rfi2bs.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="flying foxes hand upside down on branch" /> <span class="caption">Grey-headed flying foxes have recolonised parts of Melbourne.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>Citizens are good for science</h2> <p>More than 70% of Australians live in a major city. This offers a large pool of potential participants in citizen science projects.</p> <p>And cities are home to people from a variety of cultures, backgrounds, ages and mobilities. There is increasing <a href="https://academic.oup.com/jid/article/220/Supplement_2/S33/5552350">acknowledgement</a> that science is enhanced by increasing the diversity of people involved. So a greater number of urban citizen science projects would be good for science.</p> <p>What’s more, urban projects can provide data from places not typically accessible to professional scientists such as backyards and school grounds. They also allow for the collection of observation-rich and continuous data, which is rare even in professional settings.</p> <p>And of course, citizen science projects benefit the participants themselves – encouraging people to get outdoors, get active and connect more deeply with nature.</p> <p><img src="https://images.theconversation.com/files/436278/original/file-20211208-19-1ll5ixn.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="woman shows frog to school students" /> <span class="caption">Citizen science can provide data from places professional researchers can’t always access, such as schools.</span> <span class="attribution"><span class="source">Australian Museum</span></span></p> <h2>A tool for measuring change</h2> <p>Increasing citizen science in cities could help to shift an overriding narrative that cities are not important places for biodiversity. This may in turn afford greater concentrated effort towards conserving remaining urban green spaces.</p> <p>Citizen science could help answer key ecological questions about urban environments. For example, <a href="https://theconversation.com/birdwatching-increased-tenfold-last-lockdown-dont-stop-its-a-huge-help-for-bushfire-recovery-141970">research</a> last year showed how citizen scientists helped document species seeking refuge in urban areas following Australia’s horrific 2019-20 bushfires. Expanding such an approach could lead to a better understanding of how cities function as biodiversity refuges.</p> <p>And a greater focus on citizen science in cities would also enable residents to engage in their surroundings, share their knowledge and help inform the management of the environment around them.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/168256/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><span><a href="https://theconversation.com/profiles/erin-roger-1140886">Erin Roger</a>, Citizen Science Program Lead, <em><a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a></em> and <a href="https://theconversation.com/profiles/alice-motion-291397">Alice Motion</a>, Associate professor, <em><a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></span></p> <p>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
