"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>.

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>

Australia’s greater glider now an endangered species

<p>This week’s assignment of ‘endangered’ status to the greater glider may surprise many Australians, but for experts it’s hardly unexpected.</p> <p>On Tuesday, Australia’s environment minister Tanya Plibersek accepted advice from the government’s threatened species scientific committee to ‘uplist’ the conservation status of the southern and central <a href="https://cosmosmagazine.com/nature/greater-glider-glide-into-your-heart/" target="_blank" rel="noreferrer noopener" data-type="post" data-id="193138">greater glider</a> (Petauroides volans), a large marsupial that calls forests along Australia’s east coast home.</p> <p>It’s the largest of eastern Australia’s gliding possums (at least another eight are found here), known for its furry body, teddy bear-esque ears, and a canopy-like membrane that allows it to slide through the air. Individuals typically reside in ‘dens’ provided by old eucalyptus tree hollows. Some eucalypts provide the leaves that serve as their primary source of food.</p> <p>But the destruction of vital habitat during the catastrophic <a href="https://cosmosmagazine.com/earth/climate/what-fuelled-australias-black-summer-fires/" target="_blank" rel="noreferrer noopener" data-type="URL" data-id="https://cosmosmagazine.com/earth/climate/what-fuelled-australias-black-summer-fires/">Black Summer</a> bushfires in 2019-20 has pushed glider populations of the species to the brink.</p> <h2>Extended family: greater gliders are separate species and are all likely under threat</h2> <p>The greater glider was first listed as vulnerable in 2016, and was considered one species – P. volans. But since 2020, experts consider the glider to be at least three distinct species.</p> <p>P. volans inhabits forests from Proserpine in the Whitsunday region of Queensland down the continent’s east coast to the forested areas surrounding Melbourne, Victoria. P. minor occupies the wet-dry tropical region near Townsville and Cairns north-eastern Australia, and has been now added to the threatened species list as ‘vulnerable’.</p> <p>A third species – P. armillatus – is considered vulnerable by Queensland’s government, and likely faces the same pressures as the others.</p> <p>“The taxonomy of the gliders is not completely resolved as yet,” explains Professor David Lindenmayer of the Australian National University, Canberra. “There may be up to five species of greater gliders, and it’s unlikely that any of them will be secure in number.</p> <p>“We’re going to have to work hard to make sure that we can conserve all of those species because it’s all an important part of Australia’s natural heritage.”</p> <p>There is encouraging language from the Australian government, with environment minister Plibersek publicly backing efforts to help gliders recover from the Black Summer bushfires. But while those fires had a devastating effect on numerous plant and animal populations, other factors like climate change, habitat clearing and fragmentation and timber harvesting pose existential threats to glider survival.</p> <p>“All these various threats and factors interacting in different ways ultimately increase the risk of extinction,” says Luke Emerson, a researcher at Deakin University’s Centre for Integrative Ecology who specialises in the ecology of arboreal marsupials like the glider.</p> <p>“Rising temperatures, increasing fire severity, shorter fire intervals, logging on top of that, conversion and fragmentation of habitat… all these things are interacting to put greater pressure on arboreal marsupials.</p> <p>“These multiple threats are interacting in ways that we can predict, but there’s probably ways that we can’t predict that are going to negatively impact them as well.”</p> <h2>The bad list: more Australian icons added or re-graded in 2022</h2> <p>The greater glider isn’t alone in being uplisted on the nation’s threatened species register in 2022.</p> <p>Populations of the iconic koala (Phascolarctos cinereus) living in Queensland, New South Wales and the Australian Capital Territory were notably transferred from vulnerable to endangered status <a href="https://cosmosmagazine.com/nature/animals/explainer-koalas-endangered-nsw-qld-act/" target="_blank" rel="noreferrer noopener">earlier this year.</a> The yellow-bellied glider (Petaurus australis australis) and long-nosed potoroo (Potorous tridactylus trisulcatus) were listed as vulnerable in March.</p> <p>And many species other than mammals have been added to the list in 2022.</p> <p>Watson’s (Litoria watsoni) and Littlejohn’s tree frog (L. littlejohni), the gang-gang cockatoo (Callocephalon fimbriatum) and the South Australian Bassian thrush (Zoothera lunulata halmaturina) have been either added or uplisted to endangered, while the pilotbird (Pycnoptilus floccosus) was added as vulnerable.</p> <p>The work to protect animal species from spiraling further towards extinction is a difficult business at the best of times. Triumphs are rare.</p> <p>One of note is Zoos Victoria’s 33-year-old captive breeding program for eastern barred bandicoots (Perameles gunnii), which was retired in 2021 when the species – previously extinct in the wild – was downlisted to endangered. The species is now regenerating itself in specially fenced, predator free release sites across Victoria.</p> <p>For Zoos Victoria reproductive biologist Dr Marissa Parrot, the success of the bandicoot program was a career high point. But alongside these all-too-rare moments of success are declines in other species.</p> <p>“It’s such an amazing feeling to know that you’ve made a difference to a species… but it’s just one of thousands that do need help,” Parrott says. “When an animal is added to the endangered species list, they’re going to hopefully get more focus and more funding, and they need that long-term care.</p> <p>“But it also means that they’ve got to the point where they need to be added to an endangered list, and that’s quite devastating.”</p> <p>Parrott believes that improving public knowledge of both the existence of species and the threats that exist in the wild may improve outcomes for many animals.</p> <p>That knowledge-building can extend to people taking individual action – such as providing suitable food trees to support endangered animals that lose habitat, participation in citizen science programs or even turning outdoor lights off to support threatened moths.</p> <p>While the uplisting of species like the greater glider is a troubling event, Parrott say it can serve to draw people’s attention to the challenges confronting lesser-known animals.</p> <p>“Animals like the greater glider are beautiful, and they’re fluffy, and they can really grab people’s attention,” she says. “It’s great that they’re getting that attention, but we also have many species no one’s ever heard of, like the pookila (New Holland mouse), and the <a href="https://cosmosmagazine.com/australia/missing-the-bogong-moth/" target="_blank" rel="noreferrer noopener" data-type="URL" data-id="https://cosmosmagazine.com/australia/missing-the-bogong-moth/">bogong moth</a>, which is also a tiny little animal, but an amazing species.</p> <p>“Just last week I’ve seen gang gang cockatoos and grey-headed flying foxes in my own suburb – showing that these endangered species that are in trouble are actually around us [is important].”</p> <h2>Common causes and solutions for endangerment</h2> <p>The challenges confronting greater gliders are shared by these other, less prominent animals.</p> <p>While addressing climate change requires largescale transformation across society, there are other actions that can be implemented to provide more immediate relief for native species.</p> <p>Government conservation advice provided for all animals added or uplisted so far in 2022 notes land and vegetation clearing as a survival threat. For gliders, it poses a catastrophic risk.</p> <p>That’s why moving the forestry industry to an entirely plantation-based sector is a critical solution Lindenmayer believes needs to be implemented, and soon.</p> <p>“It’s time to exit native forest logging,” he says. “The Western Australians have done this: on the 31st of December 2023, [WA] will no longer be logging native forests.</p> <p>“Victoria needs to do that at the same time, so does New South Wales. It’s really important that we tackle that issue, which renders huge areas of forest unsuitable for animals like greater gliders, either permanently or for periods of up to 200 years.”</p> <p>Lindenmayer also points to non-forestry land clearing and coal mine construction in the eastern states as adding pressure to threatened forest-dwellers. But he also wants to see the government to take biodiversity seriously.</p> <p>“The federal minister can actually get involved in this seriously and not unravel, but improve, environmental laws, to make sure that more biodiversity is not lost. That’s critical.”</p> <p>Australia <a href="https://www.pnas.org/doi/10.1073/pnas.1417301112" target="_blank" rel="noreferrer noopener">accounts for 35%</a> of global modern mammal extinctions.

Australia's cutest marsupials are now an endangered species

<p>The fight is on to save Australia’s cutest icons.</p><p>Koalas are now officially an “endangered” species in NSW, Queensland and ACT after the federal government upgraded their status from “vulnerable.</p><p>The much-loved marsupials’ population has plummeted in those states over recent years and they are now at serious risk of being wiped out.</p><p>“Today I am increasing the protection for koalas in NSW, the ACT and Queensland listing them as endangered rather than their previous designation of vulnerable,” federal Environment Minister Sussan Ley said on Friday.</p><p>An endangered listing recognises that a species is at high risk of extinction.</p><p>“The impact of prolonged drought, followed by the black summer bushfires, and the cumulative impacts of disease, urbanisation and habitat loss over the past twenty years have led to the advice,” Ms Ley added.</p><p>The environment minister wants Queensland, NSW and Victoria to sign up to a national recovery plan worth $50 million over four years.</p><p>“We are taking unprecedented action to protect the koala, working with scientists, medical researchers, veterinarians, communities, states, local governments and traditional owners,” Ms Ley said.</p><p>The Australian Koala Foundation has estimated there are fewer than 100,000 koalas remaining in the wild, with feral predators and land clearing for development to blame.</p><p>The 2019-20 bushfire crisis and the drought that followed has also contributed to a rapid decline in population. In 2020, a NSW parliamentary inquiry warned the marsupial would likely become extinct before the middle of the century without urgent intervention.</p><p><em>Image: Getty</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. We are trialling these approaches in the iconic southern corroboree frog, and plan to extend them to other species if they prove effective.</p> <p>Worldwide, the disease chytridiomycosis is devastating frog populations. Caused by the fungal pathogen <em>Batrachochytrium dendrobatidis</em>, it has led to the extinction of about <a href="https://www.nationalgeographic.com/animals/article/amphibian-apocalypse-frogs-salamanders-worst-chytrid-fungus">90 frog species</a> and declines in as many as 500 others.</p> <p>Many frog species now rely on conservation breeding for their continued survival. No effective solution for restoring chytrid-susceptible frogs to the wild exists, because the fungus cannot be eradicated.</p> <p><img src="https://images.theconversation.com/files/442155/original/file-20220124-23-cebr8a.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="gloved hand removed portion of DNA strand" /> <span class="caption">CRISPR technology could potentially be used to edit the genes of endangered species.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>Looking ahead</h2> <p>As with many conservation approaches, targeted genetic intervention is likely to involve trade-offs. 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.

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. What’s more, significant gaps in the application of Indigenous Knowledge and protection of the Indigenous estate will continue.</p> <p><a href="https://images.theconversation.com/files/434973/original/file-20211201-27-tg1guw.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/434973/original/file-20211201-27-tg1guw.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="hands with green turtle eggs" /></a> <span class="caption">Rangers collecting green turtle eggs on Yanyuwa Country in the Gulf of Carpentaria.</span> <span class="attribution"><span class="source">Nicolas Rakotopare</span></span></p> <h2>A new kind of recognition</h2> <p>During the submission process of the review, <a href="https://epbcactreview.environment.gov.au/sites/default/files/2020-06/ANON-QJCP-UGT1-F%20-%20Indigenous%20Working%20Group%20-%20Threatened%20Species%20Recovery%20Hub.pdf">many</a> Indigenous and <a href="https://www.ecolsoc.org.au/news/esa-response-to-epbc-interim-report/">non-Indigenous</a> organisations <a href="https://epbcactreview.environment.gov.au/submissions/anon-qjcp-ugt1-f">lobbied</a> for the recognition of “culturally significant entities”.

They also called for the mandatory participation of Indigenous Australians in threatened species nominations, listings, policy and management.</p> <p>Many Indigenous Australians were disappointed this measure was not mentioned in Samuel’s final report.

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.

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.

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>

The first step to conserving the Great Barrier Reef is understanding what lives there

<p>Look at this photo of two coral skeletons below. You’d be forgiven for thinking they’re the same species, or at least closely related, but looks can be deceiving. These two species diverged tens of millions of years ago, probably earlier than our human lineage split from baboons and macaques.</p> <p>Scientists have traditionally used morphology (size, shape and colour) to identify species and infer their evolutionary history. But most species were first described in the <a href="https://www.nature.com/articles/027073a0">19th century</a>, and based solely on features of the coral skeleton visible under a microscope.</p> <p>Morphology remains important for species recognition. The problem is we don’t know whether a particular morphological feature reflects species ancestry, or evolved independently.</p> <p>Our new study <a href="https://www.sciencedirect.com/science/article/abs/pii/S1055790320302165">examined</a> the traditional ideas of coral species and their evolutionary relationships using “<a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1755-0998.12736">phylogenomics</a>” – comparing thousands of DNA sequences across coral species.</p> <p><strong>Join 130,000 people who subscribe to free evidence-based news.</strong></p> <p>Get newsletter</p> <p>Our results revealed the diversity and distributions of corals are vastly different to what we previously thought. It shows we still don’t know many fundamental aspects about the corals on Great Barrier Reef.</p> <p>And after three mass bleaching events in five years, not having a handle on the basics could mean <a href="http://elibrary.gbrmpa.gov.au/jspui/bitstream/11017/3569/4/Draft-restoration-adaptation-policy.pdf">our attempts to intervene</a> and help coral survive climate change may have unexpected consequences.</p> <p>An international team of scientists have developed a new genetic tool that can help them better understand and ultimately work to save coral reefs.</p> <p><strong>How do we know which species is which?</strong></p> <p>Despite being one of the <a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/j.1755-263X.2010.00146.x">best-studied</a> marine ecosystems on Earth, there are fundamental knowledge gaps around the Great Barrier Reef, including:</p> <p>1. how many coral species live there?</p> <p>2. how do we identify them?</p> <p>3. where are they found across the vast Great Barrier Reef ecosystem?</p> <p>Finding the answers to these questions starts with accurate “taxonomy” – the science of naming and classifying living things.</p> <p>Identifying species based on how similar they look may seem straightforward. As Darwin famously said, closely related species often share morphological features because they inherited them from a common ancestor.</p> <p>However, this can be misleading if two unrelated species independently acquire similar features. This process, called convergent evolution, often occurs when different species are faced with similar ecological challenges.</p> <p>A <a href="https://www.nationalgeographic.com/science/phenomena/2015/02/06/why-an-ichthyosaur-looks-like-a-dolphin/">classic example</a> of convergent evolution is dolphins and the prehistoric ichthyosaurs. These animals are unrelated, but share many similarities since they both occupy a similar ecological niche.</p> <p>Ichthyosaurs dominated the world’s oceans for millions of years.</p> <p>At the other end of the spectrum, morphology can vary considerably within a single species. An alien taxonomist visiting Earth could be forgiven for describing the Chihuahua and the Irish Wolfhound as two distinct species.</p> <p><strong>Bringing coral taxonomy into the 21st century</strong></p> <p>We used molecular phylogenetics, a field of research that uses variations in DNA sequences to reconstruct genealogies. From corals to humans, molecular phylogenetics has revolutionised our understanding of the origins and evolution of life on Earth.</p> <p>Molecular approaches have <a href="https://link.springer.com/chapter/10.1007/978-3-319-31305-4_4">revolutionised</a> our understanding of the diversity and evolution of corals, shedding light on <a href="https://www.nature.com/articles/nature02339">deeper branches</a> in the coral “tree of life”. But within hyper-diverse, ecologically-important coral groups, such as the staghorn corals from the genus <em>Acropora</em>, we are still in the dark.</p> <p><a href="https://www.sciencedirect.com/science/article/abs/pii/S1055790320302165">Our new technique</a> addresses this by comparing thousands of key regions across coral genomes (the entire genetic code of an organism) to help identify species in this ecologically important group for the first time. This method will also allow us to identify morphological features that do reflect shared ancestry and help us recognise species when diving in the reef.</p> <p>About a quarter of all coral species on the Great Barrier Reef are staghorn corals, and they provide much of the three-dimensional structure fishes and many other coral reef animals rely on, just like trees in a forest.</p> <p>Unfortunately, staghorn corals are also highly susceptible to threats such as thermal bleaching and crown-of-thorns seastar predation. The future of reefs will be heavily influenced by the fate of staghorn corals.</p> <p><strong>The risk of ‘silent extinctions’</strong></p> <p>While we don’t yet know how many coral species occur on the Great Barrier Reef or how widespread they are, many species appear to have far smaller ranges than we previously thought.</p> <p>For example, we now know some of the corals on Lord Howe Island are endemic to only a few reefs in subtropical eastern Australia and <a href="https://www.mapress.com/j/zt/article/view/zootaxa.3626.4.11">occur nowhere else</a>, not even on the Great Barrier Reef. They evolved in isolation and bleach at <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.14772">much lower temperatures</a> than corals on tropical reefs.</p> <p>This means Lord Howe Island’s corals are of far greater conservation concern than currently recognised, because <a href="https://theconversation.com/bleaching-has-struck-the-southernmost-coral-reef-in-the-world-114433">one severe bleaching event</a> could cause the extinction of these species.</p> <p>The risk of “silent extinctions”, where species go extinct without even being noticed, is one of the reasons behind the Australian Academy of Science’s <a href="https://www.science.org.au/support/analysis/decadal-plans-science/discovering-biodiversity-decadal-plan-taxonomy">Decadal Plan for Taxonomy</a>, which has led to the ambitious goal to document all Australian species in the next 25 years.</p> <p><strong>Intervening now may have unexpected consequences</strong></p> <p>In April, the <a href="https://www.gbrrestoration.org/reports#technical-reports">Reef Restoration and Adaptation Program</a> concept feasibility study found 160 possible interventions to help save the Great Barrier Reef. <a href="https://www.gbrrestoration.org/">Proposed interventions</a> include moving corals from warm to cooler waters, introducing genetically-engineered heat-tolerant corals into wild populations, and the harvest and release of coral larvae.</p> <p>What could go wrong? Well-intentioned interventions may inadvertently threaten coral communities, for example, through introduction or movement of diseases within the Great Barrier Reef. <a href="https://www.nationalgeographic.com/animals/amphibians/c/cane-toad/">Cane toads</a> are a famous example of unintended consequences: introduced in the 1930s to control an insect pest, they are now wreaking havoc on Australian ecosystems.</p> <p>Any intervention affecting the ecology of a system as complex as the Great Barrier Reef requires a precautionary approach to minimise the chance of unintended and potentially negative consequences.</p> <p>What we need, at this time, is far greater investment in fundamental biodiversity research.

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.

New “umbrella” species would massively improve conservation efforts

<p><span style="font-weight: 400;">According to new research done by the University of Queensland, the introduction of “umbrella” species would massively improve conservation efforts.</span></p> <p><span style="font-weight: 400;">Umbrella species are species which when preserved indirectly protect many other animals and plant species.</span></p> <p><span style="font-weight: 400;">UQ PhD candidate Michelle Ward said different choices in Australia could provide more assistance for threatened species.</span></p> <p><span style="font-weight: 400;">“The Australian Federal Government’s umbrella prioritisation list identifies 73 species as conservation priorities,” she said.</span></p> <p><span style="font-weight: 400;">“But this only ends up benefiting six per cent of all Australia’s threatened terrestrial species.</span></p> <p><span style="font-weight: 400;">“This figure could be increased to benefit nearly half of all threatened terrestrial species for the same budget.</span></p> <p><span style="font-weight: 400;">“One of the main reasons is that many umbrella species are chosen based on their public appeal, rather than their efficiency for protecting other species – we want to change that.” </span></p> <p><span style="font-weight: 400;">Researchers investigated what umbrella species could maximise the flora and fauna benefitting from management while considering costs, actions and threats.</span></p> <p><span style="font-weight: 400;">“The koala, red goshawk, matted flax-lily and purple clover are more efficient umbrella species, yet none of these appear on the existing federal government priority species list,” she explained.</span></p> <p><span style="font-weight: 400;">“Australia has committed to prevent further extinction of known threatened species and improve their conservation status by 2020.</span></p> <p><span style="font-weight: 400;">“Yet, with limited funding committed to conservation, we need better methods to efficiently prioritise investment of resources.”</span></p> <p><span style="font-weight: 400;">Professor Hugh Possingham said that in a time of crisis, smart decision making was vital.</span></p> <p><span style="font-weight: 400;">“Now is precisely the time where governments need to get their investment in nature to be as efficient as possible,” he said.</span></p> <p><span style="font-weight: 400;">“Nations around the world can significantly improve the selection of umbrella species for conservation action by taking advantage of our transparent, quantitative and objective prioritisation approach.</span></p> <p><span style="font-weight: 400;">“With a species extinction crisis, looming international deadlines and limited conservation funding globally, we need better methods to efficiently prioritise investment of resources in species recovery.”</span></p> <p><em><span style="font-weight: 400;">The study, published in Conservation Biology (<a href="https://www.vision6.com.au/ch/50178/3ct4h/2808599/Ds2b._AP0gyT630EB6_aQlNZXn05sHJG_MdYR0Ar.html">DOI: 10.1111/cobi.13430</a>), was conducted by UQ, <a href="https://www.vision6.com.au/ch/50178/3ct4h/2808600/Ds2b._AP0gyT630EB6_a6jGpUsKkQsMprfjcLi0h.html">The Nature Conservancy</a>, the <a href="https://www.vision6.com.au/ch/50178/3ct4h/2291364/Ds2b._AP0gyT630EB6_aeAh0IAz4MZ87vQ.Ij7du.html">Wildlife Conservation Society</a> and the <a href="https://www.vision6.com.au/ch/50178/3ct4h/2808601/Ds2b._AP0gyT630EB6_aXgEzA0c2ovhFWY3HjXCB.html">United Nations Development Program</a>.</span></em></p>
