     — 

    Extremely rare – and extremely adorable.

    The Chester Zoo in Cheshire, England, has welcomed the birth of a Western chimpanzee, the most endangered subspecies of chimpanzees.

    The zoo announced the baby boy’s birth in a Thursday news release. The little one, born to mother ZeeZee, will join a troop of 22 Western chimpanzees at the British zoo.

    “We’re incredibly proud to see a precious new baby in the chimpanzee troop,” said Andrew Lenihan, team manager at the zoo’s primate section, in the release. “Mum ZeeZee and her new arrival instantly bonded and she’s been doing a great job of cradling him closely and caring for him.”

    Lenihan said that the baby is already quickly becoming accepted by his extended family.

    “A birth always creates a lot of excitement in the group and raising a youngster soon becomes a real extended family affair,” Lenihan went on. “You’ll often see the new baby being passed between other females who want to lend a helping hand and give ZeeZee some well-deserved rest, and that’s exactly what her daughter, Stevie, is doing with her new brother. It looks as though she’s taken a real shine to him, which is great to see.”

    Additionally, the tiny baby is an essential asset to the critically endangered population.

    “He may not know it, but ZeeZee’s new baby is a small but vital boost to the global population of Western chimpanzees, at a time when it’s most needed for this critically endangered species,” Lenihan added.

    Following a decades-old tradition, Chester Zoo’s newborn will be named after a famous rock star, according to the news release.

    The Western chimpanzee is the only chimpanzee subspecies categorized as “critically endangered” by the International Union for the Conservation of Nature, which indicates they are facing “an extremely high risk of extinction in the wild.” The species has gone extinct in Benin, Burkina Faso and Togo, but still lives in some parts of West Africa, with the largest population remaining in Guinea.

    The subspecies has faced an 80% population decline over the last 25 years, according to the International Union for the Conservation of Nature. The ape’s numbers have plummeted due to habitat destruction, poaching, and disease.

  • Let’s clear things up: how do glassfrogs achieve transparency?

    Let’s clear things up: how do glassfrogs achieve transparency?

    [ad_1]

    Newswise — Tissue transparency—a useful skill for animals that want to hide from predators—is common in aquatic environments, but is extremely rare on land. One exception is the glassfrog, so named because its internal organs can be seen through its transparent skin and muscles. This frog is active at night and spends its days sleeping on leaves, becoming nearly invisible on the foliage. But how exactly this creature makes itself transparent has been somewhat of a mystery.

    Using state-of-the-art imaging technology, NIH-funded researchers have found the secret behind the glassfrog’s camouflage. Their findings, recently published on the cover of Science, demonstrate that glassfrogs can remove almost 90% of their red blood cells from circulation, storing them in the liver during rest. This mechanism, along with its inherently see-through tissues, allows the glassfrog to increase its transparency by two- to threefold, seemingly on demand.

    “In vertebrates like humans, tissue transparency is particularly difficult to achieve, as our circulatory systems are filled with oxygen-carrying red blood cells that strongly absorb light and render our tissues opaque,” explained NIBIB-funded researcher Junjie Yao, Ph.D., an assistant professor of biomedical engineering at Duke University. “In our study, we have discovered that the glassfrog can conceal nearly all of its red blood cells within its liver on a daily basis, resulting in a unique form of camouflage that is distinct from all other known mechanisms of tissue transparency. Understanding this blood flow mechanism in the glassfrog may provide insights into disorders related to blood clotting or stroke in humans.”

    The glassfrog’s camouflage is adaptive—the creature has peak transparency when it is asleep and at increased risk of attack. To understand the mechanism of this transparency, the researchers first used spectroscopy techniques to passively measure glassfrog’s levels of hemoglobin (a protein in red blood cells that carries oxygen and absorbs light). They found that hemoglobin levels were barely distinguishable when the frogs were sleeping, but markedly increased after exercise. This means that the glassfrog depletes its red blood cells from circulation during rest, allowing for enhanced tissue transparency and camouflage during this vulnerable time.

    But where exactly are these red blood cells going while the glassfrog is asleep? To answer this question, the researchers used an advanced technique called photoacoustic microscopy, a hybrid imaging method that takes advantage of both light and sound waves. Here’s how it works: When a tissue absorbs light, some of that absorbed energy is converted into ultrasound waves. Measuring these ultrasound waves with a specialized transducer can give detailed information about molecules and tissues under the skin’s surface. In this study, the researchers optimized this technique so that they could detect light absorbed by hemoglobin—this way, the resulting ultrasound waves would give information about glassfrogs’ red blood cell movement.

    “Photoacoustic microscopy allowed us to capture the blood flow dynamics of the glassfrogs, even though those changes occur deep inside their opaque internal organs,” explained Carlos Taboada, Ph.D., a postdoctoral associate at Duke University and one of the leading authors of this study. “This aspect of the technique was really important, because many internal organs of the glassfrog contain millions of nanocrystals that attenuate most incident light. Traditional imaging methods can’t track blood flow with such a high level of accuracy or tell us exactly where the glassfrogs are storing their red blood cells.”

    Using photoacoustic microscopy, the researchers imaged the glassfrogs while under anesthesia (which leads to red blood cells being distributed throughout the entire body), while sleeping, and after exercise. During rest, the researchers found that the glassfrogs’ circulating pool of red blood cells decreased by 80-90%, with the hemoglobin signal concentrated in the liver. Imaging the frogs after exercise revealed that the blood flows out of the liver and back into circulation during activity, with the red blood cells reaggregating in the liver within roughly an hour after movement.

    By revealing the mechanism of the glassfrog’s camouflage, a new question has surfaced: How do these creatures concentrate most of their red blood cells in their liver without triggering clotting events? “At this point, we really know very little about this important physiological function in glassfrogs, but we are actively working to understand this phenomenon, which has significant clinical implications,” said Yao. “This anti-clotting mechanism is highly relevant for treating thrombosis and stroke, as well as improving medical interventions that require removing blood from the body (like dialysis), where blood clotting is a major concern.”

    Future work in this space can take advantage of the unique ability of photoacoustic imaging to track glassfrog’s blood flow—in a safe and unobtrusive way that does not disturb the animals. “By optimizing photoacoustic imaging to specifically detect hemoglobin, the researchers were able to observe the glassfrogs’ natural blood flow dynamics without injecting contrast agents, representing a truly non-invasive approach,” said Randy King, Ph.D., a program director in the Division of Applied Science & Technology at NIBIB. “What’s more, this study highlights how photoacoustic microscopy can be tailored to investigate different aspects of blood dynamics, providing both high-resolution and real-time information.”

    This study was supported by grants from NIBIB (R01EB028143), the National Institute of Neurological Disorders and Stroke (NINDS; R01NS111039), and the NIH BRAIN Initiative (RF1NS115581).

    This Science Highlight describes a basic research finding. Basic research increases our understanding of human behavior and biology, which is foundational to advancing new and better ways to prevent, diagnose, and treat disease. Science is an unpredictable and incremental process—each research advance builds on past discoveries, often in unexpected ways. Most clinical advances would not be possible without the knowledge of fundamental basic research.

  • The devil is in the details: how poison-dart frogs avoid poisoning themselves

    The devil is in the details: how poison-dart frogs avoid poisoning themselves

    [ad_1]

    Newswise — On a frog-catching expedition to the jungles of Ecuador, Aurora Alvarez-Buylla, a Ph. D candidate from Dr. Lauren O’Connell’s laboratory at Stanford, recounts the astounding expertise of wildlife scientist Dr. Elicio Tapia, the “frog whisperer”. 

    “We drove a dirt road in an old, creaky Toyota. I could not hear a thing.” Tapia, one hand on the wheel and his head out the window, remained alert. The truck stops, the whisperer exclaims: “There’s a frog.” 

    Silence, then: ‘bwap-bwap-bwap’, the characteristic mating call of Oophaga sylvatica, a 1.5 inch-long poison-dart frog with yellow-marbled skin.

    Oophaga sylvatica, known by locals as ‘el Diablito’ (‘the little devil’), brands eye-snatching colors that mean BEWARE; its colorful skin is an honest signal to the frog’s predators–Diablito’s way of saying: “if you munch me, you’ll regret it!”

    Accumulated in el Diablito’s skin are toxic alkaloids; small molecules obtained from the ant and mite-rich diet poison-dart frogs consume. Inside the body of its enemies, these toxins disrupt the nervous system and muscle cells. The consequences can be as mild as a nasty taste, enough to make the predator go “yuck!” and spit Diablito out, or as potent as to cause paralysis or cardiac arrest. 

    Little is known about how poison-dart frogs achieve and survive the accumulation of potentially lethal chemicals. Alvarez-Buylla thinks that poison-dart frogs may achieve this impressive feat with the help of transporter proteins in their blood, which may hang on to the toxins and prevent them from wreaking havoc until they are shuttled to the skin.

    Alvarez-Buylla and her colleagues devised an elegant way to figure this out: they ran experiments to see if proteins in the frog’s blood were interacting with pumiliotoxin (an alkaloid often found in Diablito’s skin) and a mimic of this molecule outfitted with a light-sensitive dye. If proteins bound to the mimic, it lit up; but if the proteins preferentially bound to pumiliotoxin or other alkaloids, then the interaction was invisible. Using this comparison, the researchers were then able to identify the most prevalent protein binding to both the mimic and the alkaloid, and appropriately baptized it alkaloid binding globulin (ABG). 

    With a clear protein candidate, Alvarez-Buylla and colleagues found that ABG is not only present in the blood, but also in the gut, liver, and, most importantly, the skin, highlighting its critical role in toxin transport throughout the body. What’s more, the scientists found that ABG also competes to bind a wider variety of alkaloid toxins. 

    Although Alvarez-Buylla’s work focused on frog toxin metabolism, it may have broader implications for bioengineering and poison therapy. “Studying weird animals is useful because you find examples of how nature has crafted clever solutions to problems, problems we may run into in the future.” 

    The results of this research project will be presented by Aurora Alvarez-Buylla at SICB 2023 in Austin, TX.

  • Current Antarctic conservation efforts are insufficient to avoid biodiversity declines

    Current Antarctic conservation efforts are insufficient to avoid biodiversity declines

    [ad_1]

    Newswise — Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent’s plants and wildlife by the year 2100, according to a study by Jasmine Rachael Lee at the University of Queensland, Australia, and colleagues, publishing December 22nd in the open access journal PLOS Biology. Implementing ten key threat management strategies — at an annual cost of 23 million US dollars — would benefit up to 84% of terrestrial bird, mammal, and plant groups.

    To better understand which species are most vulnerable and identify the most cost-effective actions, researchers combined expert assessments with scientific data to evaluate threats and conservation strategies for Antarctica. They asked 29 experts to define possible management strategies, estimate their cost and feasibility, and assess the potential benefit to different species between now and 2100.

    Climate change was identified as the most serious threat to Antarctic biodiversity and influencing global policy to limit warming was the most beneficial conservation strategy. Under current management strategies and more than 2 degrees Celsius of warming, 65% of land plants and animals will decline by 2100. Emperor penguins (Aptenodytes forsteri) were identified as the most vulnerable, followed by other sea birds and soil nematode worms. However, regional management strategies could benefit up to 74% of plants and animals at an estimated cost of 1.92 billion US dollars over the next 83 years, equating to 0.004% of global GDP in 2019. The regional management strategies identified as offering the greatest return on investment were minimizing the impacts of human activities, improving the planning and management of new infrastructure projects, and improving transport management.

    As Antarctica faces increasing pressure from climate change and human activities, a combination of regional and global conservation efforts is needed to preserve Antarctic biodiversity and ecosystem services for future generations, the authors say.

    Lee adds, “What this work shows is that climate change is the greatest threat to Antarctic species and what we need is global mitigation efforts to save them. This will not only help to secure their future, but also our own.”

  • Study reveals the true value of elephants

    Study reveals the true value of elephants

    [ad_1]

    Newswise — New research examining the services and benefits of elephants has revealed many values are often overlooked when deciding how they should be protected.

    The collaboration between universities in England and South Africa, including the University of Portsmouth, found conservation strategies often have a narrow focus and tend to prioritise certain values of nature, such as economic or ecological, over moral ones. 

    When looking specifically at elephants, the study found financial benefits including ecotourism, trophy hunting and as a source of ivory or labour, often conflicts with the animal’s ecological, cultural and spiritual contributions.

    The authors argue not fully understanding or considering the value systems of all stakeholders involved in conservation, including local people, leads to social inequality, conflict and unsustainable strategies. 

    Study co-author Antoinette van de Water, from the University of KwaZulu-Natal in South Africa, said: “We chose to look at elephants as the case study because their conservation can be especially challenging and contentious. 

    “We’re not saying economic contributions aren’t important, but there’s a lot of different values at play and they all need to be considered in conservation strategies if they are going to succeed.”

    The study also highlights conservation decision makers tend to take a single worldview when considering the value of nature. 

    Co-author Dr Lucy Bates, from the University of Portsmouth, explained: “Whether it’s economic, ecological, or social, a blanket approach to values can impact the success of a conservation strategy.

    “Consider something like the ivory trade for example. International trade in ivory is illegal, but many southern African countries want to restart the trade leading to contention across the African continent. If you focus less on the potential economic value of ivory, and turn to other ways elephants can support communities, it can be a game-changer.

    “On a smaller scale, you can also apply this framework to defining protected areas and what land could be made available to elephants. By listening to those living in these areas, you can get a clear understanding of how decisions will affect human life as well, and work out ways to resolve any issues.”

    The paper, published in Ecosystems Services, says nature’s non-material benefits include recreation, inspiration, mental health, and social cohesion. 

    But it points out broader moral values, such as human rights, environmental justice, rights of nature and intergenerational legacy, also have a big part to play in the success of conservation.

    The study recommends incorporating moral values related to biodiversity conservation into the valuation framework to create a positive loop between benefits to humans and to nature. 

    The researchers believe that this approach will help policymakers and managers have a better understanding of what elephants mean to people, why elephants are important in themselves, and what values and interests are at stake. It can also be applied to other species and ecosystems. 

    “What is really needed is a change of thinking”, added Antoinette van de Water. 

    “Conservation policies are often based on price tags. Our pluralist valuation system provides solutions that are not based on economic gains or political status for the few, but instead on long-term common good and the goals and aspirations of societies.”

  • Government Funding Bill Includes 11th-Hour Carveout For Lobster Industry

    Government Funding Bill Includes 11th-Hour Carveout For Lobster Industry

    [ad_1]

    Despite fierce pushback from environmentalists, congressional leaders have included a controversial rider in the $1.7 trillion federal government funding package that would block stricter federal rules meant to protect the endangered North Atlantic right whale from becoming entangled in fishing gear.

    As HuffPost first reported Friday, Maine’s congressional delegation, including Sen. Susan Collins (R), championed the provision and lobbied for its inclusion, arguing that it would provide relief to a lobster industry that they say has been the target of unfair and misguided regulations.

    Collins’ office called the proposal “a simple compromise.” Environmentalists have warned it could drive the right whale to extinction.

    In July, a federal judge ruled that a 2021 regulation that established new requirements for lobster traps to reduce the risk of entangling whales didn’t go far enough. Among other things, the National Oceanic and Atmospheric Administration rules limited the number of vertical fishing lines that could be deployed in Maine waters and set new seasonal zone restrictions. The judge ruled that the regulations fell short of fulfilling two key environmental laws: the Endangered Species Act and the Marine Mammal Protection Act.

    The Maine delegation’s measure effectively voids the judge’s ruling and blocks stricter rules that the court ordered federal agencies to finalize by 2024.

    An initial draft of the provision would have cemented the 2021 regulation for 10 years. The measure was modified during negotiations, with the exemption reduced from 10 years to six. The provision also sets aside grant funding — $50 million per year through 2032 — to reduce the risk of entanglement, vessel strikes and other threats to the imperiled whale species. That includes $40 million earmarked for “innovative gear deployment and technology.”

    The changes did little to satisfy environmentalists, who rallied over the weekend in an effort to block the proposal.

    Brett Hartl of the Center for Biological Diversity ― one of three organizations that sued the federal government to force stronger safeguards for right whales ― said Senate Majority Leader Chuck Schumer (D-N.Y.) and Appropriations Committee Chair Patrick J. Leahy (D-Vt.) had “heartlessly put special interests above our nation’s beautiful natural heritage.”

    “Sacrificing a great whale to extinction in exchange for funding the government is immoral,” Hartl, the organization’s government affairs director, said in a statement. “Doing so just to give Sen. Schumer another political chit in his pocket is simply pathetic.”

    The office of Sen. Susan Collins (R) called the provision “a simple compromise.”

    Connor Fagan, federal policy manager at ocean advocacy group Oceana, called the move “a bridge too far.”

    “Environmentalists won’t soon forget the last-minute nature of this enormous carveout of our foundational environmental laws,” he said. “The effect of this shortsighted giveaway is likely to be disastrous for the whales.”

    Over the weekend, more than 70 organizations, including the Center for Biological Diversity and Oceana, signed a letter urging Schumer, House Speaker Nancy Pelosi (D-Calif.) and other Democratic leaders to reject the measure. They said the provision “would set a damaging precedent for the political override of science-based decisionmaking under the Endangered Species Act and Marine Mammal Act; undermine active federal litigation and reverse judicial orders; and further threaten the survival of the critically endangered North Atlantic right whale.”

    The North Atlantic right whale is among the most critically endangered species on the planet. Its population has been steadily falling since 2010, and fewer than 350 of the whales are estimated to be alive. Entanglements in fishing gear, vessel strikes and climate change are the biggest threats to their survival.

    In a separate letter to Democratic leadership on Sunday, members of the Atlantic Scientific Review Group, which advises federal agencies on marine mammals on the Atlantic coast, said the Maine delegation’s amendment “would likely doom the North Atlantic right whale to extinction.”

    Maine lawmakers have dismissed conservationists’ concerns.

    “Maine’s lobstering community has consistently demonstrated their commitment to protecting right whales,” Collins’ spokesperson Christopher Knight previously told HuffPost. “If these groups are unwilling to agree to something so straightforward, it shows an utter disdain for the men and women who make their living from one of the best managed and sustainable fisheries on earth.”

    Asked if environmental groups were considering future legal action, Hartl said the provision’s language precludes litigation and likely can’t be overturned. He expects the measure will ultimately shift the burden of protecting right whales to other ocean users.

    “To stop the slide towards extinction, the National Marine Fisheries Service must reduce the cumulative harm and impacts to right whales,” he said. “If it is prohibited from addressing the impacts of the lobster fishery, it must address the other threats more aggressively, including offshore wind, vessel strikes and all other fisheries-related impacts.”

  • Learning from habitat ‘haves’ to help save a threatened rattlesnake

    Learning from habitat ‘haves’ to help save a threatened rattlesnake

    [ad_1]

    Newswise — COLUMBUS, Ohio – Comparing the genetics and relocation patterns of habitat “haves” and “have-nots” among two populations of threatened rattlesnakes has produced a new way to use scientific landscape data to guide conservation planning that would give the “have-nots” a better chance of surviving.

    The study suggests that a collection of six relatively closely situated but isolated populations of Eastern massasauga rattlesnakes in northeast Ohio could grow their numbers if strategic alterations were made to stretches of land between their home ranges. The findings contributed to the successful application for federal funding of property purchases to make some of these proposed landscape changes happen.

    Reconnecting these populations could not only help restore Eastern massasaugas to unthreatened status, but establish a thriving habitat for other prey and predator species facing threats to their survival – satisfying two big-picture conservation concerns, researchers say. 

    “We aren’t just protecting massasaugas – we’re protecting everything else that’s there,” said H. Lisle Gibbs, professor of evolution, ecology and organismal biology at The Ohio State University and senior author of the study. “Even though we are focused on this species, protection of the habitat has all these collateral benefits.” 

    The research was published recently in the journal Ecological Applications

    Eastern massasauga rattlesnakes live in isolated spaces in midwestern and eastern North America and were listed as threatened under the Endangered Species Act in 2016 because of loss and fragmentation of their wetland habitat. 

    This study involves two known groups of Eastern massasaugas in Ohio: The Killdeer Plains Wildlife Area in north central Ohio, home to one of the most genetically diverse and largest populations in the country, numbering in the thousands, and six small, separate populations of Eastern massasaugas clustered near each other in Ashtabula County. 

    Study co-author Gregory Lipps, a field biologist at Ohio State, has studied the northeast Ohio groups for years. Federal officials once told him the populations are too small in number to be viable – but the genetics portion of this study showed that the populations had once been connected and deserve a second chance to rebuild. 

    “So now we are working on trying to reconnect them, to get them back to a viable population large enough to sustain itself even when disturbances happen that cause populations to fluctuate,” Lipps said. 

    First author Scott Martin, who completed this work as a PhD student in Gibbs’ lab, had previously sequenced genomes of 86 snakes from the six fragmented sites in northeast Ohio. For a genetic comparison in this new study, the team captured and collected blood samples from 109 snakes living together in the Killdeer Plains site. The genetic analysis, combined with where snakes were located at the time of capture, showed that the snakes living in fragmented sites in northeast Ohio were very distantly related, having stopped mingling at least three generations ago. 

    “Once we knew that they didn’t seem to be moving around, the real question is why aren’t they moving? It’s not that big of a distance – so we focused on finding out what was stopping them from being connected,” Martin said.

    Previous research had indicated how far a male Eastern massasauga snake could safely travel to find a mate and establish a family in a new location. GPS and genetic data from the Killdeer Plains and northeast Ohio population samples showed how much movement was common among related snakes in a successful group, and how uncommon relocation was among snakes living in fragmented habitats. Martin came up with the idea to combine all the data to see what was different about the landscapes in the two regions – and what could be interfering with snake relocation in the Ashtabula County groups. 

    “It seemed to be about specific features of the habitat,” Martin said. “If the snakes in northeast Ohio were moving as far as we would expect them to based on how the Killdeer snakes move and data on the species’ range, they should be able to move between these little sites. And yet when we look at the genetics and use pedigrees to see if there is any breeding between the sites, there’s just not.” 

    Using landscape maps, the researchers created models from the data that detailed the “resistance value” of various landscape features that would either help or hinder the northeast Ohio snakes’ movement to find mates. Wooded areas, cropland, and roads and housing developments – also called impervious surfaces – were found to be the main obstacles to snake relocation. Wet prairies are the ideal habitat for Eastern massasaugas. 

    “You can imagine two snakes in the same habitat that are probably likely very genetically similar because they can move easily. And then in this other region you have two snakes near each other, but on either side of a four-lane highway, and they will be genetically different because snakes don’t move across that highway, and over time they’ve diverged,” Martin said.

    “That means a highway would have a high resistance value and an open field would have a very low resistance value.” 

    These findings, and Lipps’ longtime work with northeast Ohio landowners and numerous conservation agencies, helped Ohio and Michigan collaborate on applying for and receiving a $2.3 million grant from the U.S. Fish and Wildlife Service to acquire land to benefit Eastern massasaugas in both states. 

    “To me, this is a clear example of where Ohio State basic research has produced practical results that have then been directly used to help conserve wildlife in Ohio – in other words, achieving one of the goals of a land-grant institution, which is to provide useful, practical knowledge of value to the citizens of the state,” Gibbs said.

    This research was supported by the State Wildlife Grants Program, administered jointly by the U.S. Fish and Wildlife Service and the Ohio Division of Wildlife, the Ohio Biodiversity Conservation Partnership and the National Science Foundation

    William Peterman, School of Environment and Natural Resources at Ohio State, was also a co-author on this study.

  • Beloved Mountain Lion P-22 Euthanized After Likely Being Hit By Vehicle

    Beloved Mountain Lion P-22 Euthanized After Likely Being Hit By Vehicle

    [ad_1]

    A famed mountain lion was euthanized Saturday morning after wildlife officials determined he had likely been hit by a vehicle.

    P-22, a male cougar estimated to be about 12 years old, was suffering from “several severe injuries and chronic health problems,” according to a statement from the California Department of Fish and Wildlife.

    A mountain lion in the wild is considered to be in “old age” after 10, according to the Mountain Lion Foundation.

    P-22 had been tranquilized Monday in Los Angeles’ Los Feliz neighborhood for a medical exam. Prior to his capture, wildlife officials expressed worry that he was “exhibiting signs of distress.” The big cat had also raised concerns after snatching a leashed Chihuahua from a dog walker last month. The dog did not survive.

    Veterinarians with the San Diego Zoo Safari Park found that P-22 had “significant trauma” to his head and internal organs, according to the wildlife department. This confirmed suspicions that he had suffered a recent injury, which officials said was likely a vehicle strike. He also had kidney disease, arthritis and “extensive” parasitic skin infection. The combination of these conditions and his age led the veterinary team to “unanimously” recommend euthanasia.

    P-22 first appeared in Los Angeles’ Griffith Park in 2012, the Los Angeles Times said in its comprehensive obituary of the celebrated cat. Scientists fitted him with a radio collar to study his movements, and he quickly became a local celebrity. His star continued to rise with a story from the Times that year and then a National Geographic profile.

    To get to the park from his presumed birthplace in the Santa Monica Mountains, P-22 had to cross two perilous freeways, the 405 and 101. Though he survived the journey, he was left more or less boxed in by the busy roads and would have had to cross back to find a mate. Instead, he roamed the Los Angeles area solo for a decade.

    When environmentalists proposed a wildlife bridge over the 101 to help animals cross the freeway, P-22 became the face of the project. Construction on the bridge began in April, the Times noted.

    He also became the poster animal for efforts to ban rodenticides after he became ill in 2014 following rat poison exposure.

    Fans of P-22 mourned his loss, and conservation advocates hoped that even after his death, he would continue to spur change to protect mountain lions from threats like vehicle strikes.

    “My heart breaks for P-22,” J.P. Rose, the policy director for the Center for Biological Diversity’s Urban Wildlands program, said in a statement sent to HuffPost. “I hope we can channel this grief into action to safely coexist with and protect mountain lions, which are headed toward extinction in Southern California.”

  • Why aren’t all black bears black?

    Why aren’t all black bears black?

    [ad_1]

    Newswise — Sometimes a name is just a name. Take bears, for example. In Yellowstone National Park, black bears outnumber their brownish-colored grizzly bear cousins, and in coastal areas of the Pacific Northwest, if someone says “brown bear,” they mean grizzly bear. But not all brown bears are grizzly bears.

    American black bears (Ursus americanus), which one would logically assume are, well, black, actually come in a range of colors, including brown (also known as cinnamon), blond, or bluish-grey. Others have coats that are a mixture of several colors. So, how do you tell a cinnamon-colored Ursus americanus from its brown (grizzly) Ursus arctos cousin? Differences in body shape and size can be subtle. One hypothesis for the cinnamon color of Ursus americanus is that it mimics the appearance of a grizzly bear, helping with camouflage or defense.

    Now, researchers at HudsonAlpha, the University of Memphis, and the University of Pennsylvania, have discovered what causes the cinnamon color, which sheds some light on this color confusion.

    Gene variant responsible for cinnamon morph black bear

    Emily Puckett, PhD, an Assistant Professor of Biological Sciences at the University of Memphis, has devoted her career to learning more about the evolution and genetics of bears. With help from partners in state, provincial, and federal wildlife agencies, she collected hundreds of DNA and hair samples from North American bears. She teamed up with Greg Barsh, MD, PhD, Faculty Investigator at HudsonAlpha, and animal pigmentation expert to figure out why black bears aren’t always black.

    In mammals, pigment is produced by skin cells called melanocytes. There are two types of melanin: eumelanin is black or brown, and pheomelanin is red or yellow. It is widely accepted that genetic variation in melanin biosynthesis gives rise to differences in hair, eye, and skin color. By studying photos of bears and chemically analyzing their corresponding hair samples, the team determined that cinnamon-colored black bears have reduced amounts of eumelanin, just like grizzly bears. 

    Genome sequence analysis of nearly 200 bears uncovered different missense mutations in the gene Tyrosinase-related protein 1 (TYRP1): cinnamon-colored black bears have a mutation called TYRP1R153C, while most (but not all) grizzly bears have a mutation called TYRP1R114C. The TYRP1 gene produces an enzyme within melanocytes that helps produce eumelanin, so it makes sense that the cinnamon and grizzly bears have less eumelanin. Furthermore, functional studies carried out by Mickey Marks, PhD, Professor of Pathology at the University of Pennsylvania, and his lab, determined that the TYRP1R153C and TYRP1R114C mutations interfere with melanin synthesis and distribution.

    “When we looked at other species, we were surprised to find the TYRP1R153C variant responsible for cinnamon U. americanus is identical to one previously described as a cause of oculocutaneous albinism (OCA3) in humans,” says Barsh. OCA3 is characterized by reddish skin and hair and frequent visual abnormalities and is most common in people of African or Puerto Rican ancestry. But according to Puckett, bears with TYRP1 mutations have normal skin and can see just fine.

    When and where did the cinnamon morph arise?

    The TYRP1R153C variant was primarily found in the southwest United States, at lower frequencies moving northward to Southeast Alaska and the Yukon Territory. TYRP1R153C was associated with the cinnamon color in black bears and the chocolate and light brown colors, meaning it accounts for almost all of the color diversity among U. americanus.

    The researchers used their data to learn more about the TYRP1R153C mutation. One hypothesis is that it may have started in grizzly bears and then was transferred to black bears, but demographic analysis indicated that was not the case. Instead, the TYRP1R153C mutation arose spontaneously about 9,360 years ago in black bears living in the western United States, then spread as the bears moved across their current geographic range.

    “Based on its wide range today, the TYRP1R153C mutation that arose in black bears over 9,000 years ago probably gave an advantage to the cinnamon bears,” says Puckett. “We used genetic modeling and simulations to predict the selective forces acting on the cinnamon morph. But our predictions ruled out the grizzly mimicry hypothesis as well as another hypothesis having to do with thermoregulation.”

    As to why the coat color variant arose in the first place, the team presents a new hypothesis: crypsis. Crypsis refers to the ability of an animal to conceal itself and blend into the environment. Generally, crypsis is found in prey species and ambush predators who color match within their environments. Here, the researchers suggest crypsis as a broader adaptive mechanism for large-bodied species.

    “These results illustrate how genetic variation in melanin biosynthesis can underlie iconic phenotypes and inform our understanding of color variation and recent evolution in large carnivores,” says Barsh.

  • Planned wind farm told it will need to shut down for five months a year to protect parrots

    Planned wind farm told it will need to shut down for five months a year to protect parrots

    Plans for a major new wind farm in Australia were given the thumbs up this month — on the provision its turbines go offline for five months a year to protect a parrot species.

    In an environmental assessment report of the Robbins Island Renewable Energy Park, Tasmania’s Environment Protection Authority said its board had “determined to approve the proposal” for the project, which could have as many as 122 wind turbines and is overseen by ACEN Australia.

    One of the approval conditions relates to the Orange-bellied parrot, which the Australian government says is critically endangered.

    “Unless otherwise approved in writing by the EPA Board, all WTG [wind turbine generators] must be shut down during the northern OBP migration period (1 March to 31 May inclusive) and the southern OBP migration period (15 September to 15 November inclusive),” the EPA document says.

    Read more about energy from CNBC Pro

    In a statement last week, EPA board chair Andrew Paul said the organization had concluded that “significant mitigation measures” were needed in relation to “potential impacts on the orange-bellied parrot population.”

    This was due to “the limited knowledge about the importance of Robbins Island in the annual northern and southern migrations” as well as a need to account for a National Recovery Plan for the species.

    “This has led to the inclusion of [project approval] condition FF6 which imposes shutdown periods during the migrations totaling five months when the turbines cannot operate,” Paul added.

    Robbins Island is located in waters off the northwest coast of Tasmania, a large island and Australian state. If all goes to plan, the total capacity of the proposed wind farm could be as much as 900 megawatts.

    CNBC contacted ACEN Australia via the Robbins Island project’s website, but did not receive a response prior to publication. The Ayala Corporation, parent company of ACEN Australia majority-owner ACEN Corporation, did not respond to a CNBC request for comment.

    In a Facebook post, project developers said they welcomed approval from the EPA, adding that further approvals were needed from the Circular Head Council and the Commonwealth Government’s Department of Climate Change, Energy, the Environment and Water. These were expected in early 2023, they said.

    In comments reported by the Australian Broadcasting Corporation, ACEN Australia Chief Operating Officer David Pollington described the switch-off condition as “completely unexpected.”

    The firm would “need to consider our options going forward,” the ABC report quoted Pollington as saying.

    Stock picks and investing trends from CNBC Pro:

    Amid global plans to ramp up wind power capacity in the years ahead, the interaction of wind turbines with the natural world — including marine and bird life — is likely to become a key area of debate.

    The U.K.-based Royal Society for the Protection of Birds warns that wind farms “can harm birds through disturbance, displacement, acting as barriers, habitat loss and collision,” adding that “impacts can arise from a single development and cumulatively multiple projects.”

    The U.S. Energy Information Administration has said that some wind projects and turbines can result in bat and bird casualties.

    “These deaths may contribute to declines in the population of species also affected by other human-related impacts,” it notes. “The wind energy industry and the U.S. government are researching ways to reduce the effect of wind turbines on birds and bats.”

    Brussels-based industry body WindEurope says the effects of projects can be prevented “by adequately planning, siting, and designing wind farms.”

    “The impact of wind farms on birds and bats is extremely low compared to the impact of climate change and other human activity,” it adds.

  • 20 new gurgling and creaking frog species from Madagascar named

    20 new gurgling and creaking frog species from Madagascar named

    [ad_1]

    Newswise — Taxonomists are working against the clock to discover and catalogue new species before they disappear, to make it possible to protect our planet’s remaining biodiversity. Major strides are needed to move towards completing the biological inventory on Earth. Now, a large international team has made a huge stride forward on the taxonomy of Madagascar’s frogs, naming 20 new species at once. The article was published under open access in the journal Megataxa.

    The frogs belong to the genus Mantidactylus subgenus Brygoomantis, which contained just 14 species until now. These small, brown frogs are ubiquitous along streams in Madagascar’s humid forests, but are inconspicuous to the eye. The males emit very subtle advertisement calls to attract females. ‘The calls typically sound like a creaking door, or a gurgling stomach’ says lead author, Dr Mark D. Scherz, Curator of Herpetology at the Natural History Museum of Denmark, ‘Finding, recording, and catching calling individuals of these frogs is a real challenge, but has proven critically important for the discovery and description of these many new species. That means a lot of time on hands and knees in the mud.

    The team has been building to this for a long time. ‘This is the culmination of intensive fieldwork across Madagascar over more than 30 years’ says Dr Frank Glaw, Curator of Herpetology at the Zoologische Staatssammlung München, in Munich, Germany, ‘Our dataset contains genetic data from over 1300 frogs, and measurements of several hundred specimens.

    One key tool in the authors’ arsenal was the use of cutting-edge ‘museomics’, where DNA is sequenced from old museum material. This is often difficult, because DNA degrades over time and due to various chemicals that are used to preserve animal specimens. But using an approach called ‘DNA Barcode Fishing’, the team were able to get useable DNA sequences from most of the relevant museum material. ‘Museomics gave definitive identifications of sometimes very ambiguous-looking specimens,’ says senior author, Professor Miguel Vences of the Technische Universität Braunschweig, ‘This gives us a level of confidence in our species descriptions that was not previously possible based on morphology alone.’

    Even this huge stride forward doesn’t seem to be the last word on the subgenus Brygoomantis. ‘There are still several Brygoomantis lineages that are probably separate species, but that we didn’t have enough data or material for,’ says Dr Andolalao Rakotoarison, co-chair of the Amphibian Specialist Group for Madagascar, ‘Even for those species for which we have names, we know almost nothing about their biology or ecology. We need a lot more field research on these frogs, and more specimens in museum collections, to really gain a good understanding of them.’

  • Researchers find the snake clitoris

    Researchers find the snake clitoris

    [ad_1]

    Newswise — An international team of researchers, led by the University of Adelaide has provided the first anatomical description of the female snake clitoris, in a first-of-its-kind study.

    PhD Candidate Megan Folwell from the School of Biological Sciences, University of Adelaide, led the research.

    “Across the animal kingdom female genitalia are overlooked in comparison to their male counterparts,” said Ms Folwell.

    “Our study counters the long-standing assumption that the clitoris (hemiclitores) is either absent or non-functional in snakes.”

    The research involved examination of female genitalia in adult snake specimens across nine species, compared to adult and juvenile male snake genitalia.

    Associate Professor Kate Sanders, School of Biological Sciences, University of Adelaide, said: “We found the heart-shaped snake hemiclitores is composed of nerves and red blood cells consistent with erectile tissue – which suggests it may swell and become stimulated during mating. This is important because snake mating is often thought to involve coercion of the female – not seduction.”

    “Through our research we have developed proper anatomical descriptions and labels of the female snake genitalia. We can apply our findings to further understand systematics, reproductive evolution and ecology across snake-like reptiles, such as lizards.”

    The study was published in the Proceedings of the Royal Society B Journal

    “We are proud to contribute this research, particularly as female genitalia across every species is unfortunately still taboo,” said Ms. Folwell.

    “This discovery shows how science needs diverse thinkers with diverse ideas to move forward.”Associate Professor Kate Sanders, from the School of Biological Sciences, the University of Adelaide.

    Associate Professor Sanders added the research would not have happened without Ms Folwell’s fresh perspective on genital evolution.

    “This discovery shows how science needs diverse thinkers with diverse ideas to move forward,” she said.

    The snakes studied included the Acanthophis antarcticus (also known as the Death adder), Pseudechis colleti, Pseudechis weigeli, and Pseudonaja ingrami (native to different parts of Australia), the Agkistrodon bilineatus (native to Mexico and Central America as far south as Honduras), Bitis arietans (native to semiarid regions of Africa and Arabia), Helicops polylepis (from Estación Biológica Madre Selva, Peru), Lampropeltis abnormal (from Los Brisas del Mogoton, Nicaragua), and Morelia spilota (native to Australia, New Guinea (Indonesia and Papua New Guinea), Bismarck Archipelago, and the northern Solomon Islands.)

    Holyoake College in Massachsuets, the School of Agriculture at La Trobe University, the South Australian Museum, and the Museum of Ecology and the area of Ecology and Evolutionary Biology at the University of Michigan, also contributed to this research.

  • Reliance on moose as prey led to rare coyote attack on human

    Reliance on moose as prey led to rare coyote attack on human

    [ad_1]

    Newswise — COLUMBUS, Ohio – Wildlife researchers have completed a study that may settle the question of why, in October 2009, a group of coyotes launched an unprovoked fatal attack on a young woman who was hiking in a Canadian park. 

    By analyzing coyote diets and their movement in Cape Breton Highlands National Park, where the attack occurred on a popular trail, the researchers concluded that the coyotes were forced to rely on moose instead of smaller mammals for the bulk of their diet – and as a result of adapting to that unusually large food source, perceived a lone hiker as potential prey. 

    The findings essentially ruled out the possibility that overexposure to people or attraction to human food could have been a factor in the attack – instead, heavy snowfall, high winds and extreme temperatures created conditions inhospitable to the small mammals that would normally make up most of their diet. 

    “The lines of evidence suggest that this was a resource-poor area with really extreme environments that forced these very adaptable animals to expand their behavior,” said lead author Stan Gehrt, a wildlife ecologist at The Ohio State University. 

    “We’re describing these animals expanding their niche to basically rely on moose. And we’re also taking a step forward and saying it’s not just scavenging that they were doing, but they were actually killing moose when they could. It’s hard for them to do that, but because they had very little if anything else to eat, that was their prey,” he said. “And that leads to conflicts with people that you wouldn’t normally see.”

    The research is published in the Journal of Applied Ecology

    The death of 19-year-old folk singer Taylor Mitchell is the only fatality resulting from a coyote attack on a human adult ever documented in North America. 

    Gehrt, who leads the Urban Coyote Research Project that has monitored coyotes living in Chicago since 2000, was consulted by media for his expertise after the attack. In urban areas like Chicago, where thousands of coyotes live among millions of people, injuries from coyote-human encounters are very rare. 

    “We had been telling communities and cities that the relative risk that coyotes pose is pretty low, and even when you do have a conflict where a person is bitten, it’s pretty minor,” said Gehrt, a professor in Ohio State’s School of Environment and Natural Resources. “The fatality was tragic, and completely off the charts. I was shocked by it – just absolutely shocked. 

    “A lot of people began wondering if we were at the front edge of a new trend, and if coyotes were changing their behavior. And we didn’t have good answers.” 

    Gehrt expanded an initial investigation of the fatal attack – and a few dozen less severe human-coyote incidents in the park before and after Mitchell’s death – into a detailed field study. Between 2011 and 2013, he and colleagues captured 23 adult and juvenile coyotes living in the Cape Breton park and fitted them with devices to document their movement and use of space. 

    To obtain dietary information, the team also snipped whiskers from the live-captured coyotes and from the bodies of coyotes implicated in the fatal attack and in other human-coyote incidents. For comparison, the researchers collected fur from potential prey – southern red-backed voles, shrews, snowshoe hare, white-tailed deer and moose – and hair from local barbershops that served as a proxy for human food.

    Seth Newsome, professor of biology at the University of New Mexico and corresponding author of the study, analyzed stable isotopes of carbon and nitrogen in these whisker and hair samples to determine what the coyotes had been eating in the months before they were captured or lethally removed from the population. 

    The analysis showed that, on average, moose constituted between half and two-thirds of the animals’ diets, followed by snowshoe hare, small mammals and deer. 

    “This dietary evidence was the critical piece to it,” Gehrt said. “Their diets changed because they’re taking advantage of whatever different food items are available at the time. We’re used to seeing big oscillations across the segments of whiskers depending on the season. But in this system, for these coyotes, we don’t see that – they flat line at the moose end, so there’s very little variation in their diet.”

    Samples from the coyotes that were confirmed to have been involved in the fatal attack showed they had been eating only moose, “and their diet wasn’t changing,” he said. An analysis of coyote droppings confirmed the isotope findings. The researchers found only a few examples of individual animals having eaten human food. 

    Beyond the dietary analysis, Gehrt and colleagues did test for the possibility that coyotes were familiar with humans, and therefore not fearful around people. The movement patterns showed that while the coyotes’ space use was extensive – likely related to the need to search far and wide for prey – the animals largely avoided areas of the park frequented by people and were more active at night during periods when daytime human use was at its highest. Prohibition on hunting and trapping in the park also removed a human threat. 

    “It’s a big area for these coyotes to live in and never have a negative experience with a human – if they have any experience at all,” Gehrt said. “That also leads to the logical assumption that we’re making, which is that it’s not hard for these animals to test to see whether or not people are a potential prey item.” 

    In cities and most other wilderness areas where coyotes live, food of all types is plentiful – suggesting only areas low on natural prey, like islands and remote northern climates, would pose a similar risk for coyote-human interactions, Gehrt said. Their survival in Cape Breton, he said, is attributable to their remarkable ability to adjust to their environment.

    “These coyotes are doing what coyotes do, which is, when their first or second choice of prey isn’t available, they’re going to explore and experiment, and change their search range,” he said. “They’re adaptable, and that is the key to their success.” 

    This work was supported by Parks Canada, the Nova Scotia Department of Lands and Forestry, and the Max McGraw Wildlife Foundation.

    Mark, Albania’s last ‘restaurant bear,’ arrives at sanctuary after over 20 years of captivity | CNN

    [ad_1]



    CNN
     — 

    After over twenty years in captivity, Mark, the last of Albania’s “restaurant bears,” has safely arrived at his new home, an animal sanctuary in Austria, according to the animal rescue group Four Paws International.

    So-called “restaurant bears” have historically been kept in tiny cages near restaurants or hotels, where they served as an attraction for tourists, according to Four Paws. In 2016, the nonprofit launched the “Saddest Bears” campaign in an effort to relocate the more than 30 bears being used as entertainment in the country.

    Mark, a 24-year old brown bear, is the last known “restaurant bear” in Albania, according to a news release from Four Paws, although there are other bears in captivity in poor circumstances in the country. He was rescued on December 7 and arrived at his new home, “BEAR SANCTUARY Arbesbach” in Austria on Friday.

    When Four Paws first encountered Mark, the animal was suffering from severe health problems. He was overweight, had broken teeth and displayed “abnormal” behaviors like pacing due to the lack of stimulation in his cramped cage, Four Paws said in a previous news release.

    The bear embarked on a 44-hour journey to his new home, according to the organization. He traveled through North Macedonia, Greece, Bulgaria, Romania, and Hungary before finally reaching the sanctuary.

    But he was “calm and relaxed” during the trek, according to Four Paws.

    “We made regular stops for our accompanying vet to check on him and fed him with fruits and vegetables,” Magdalena Scherk-Trettin, who coordinates Four Paws’ wild animal rescue and advocacy projects, said in the release. “After receiving an inappropriate diet of restaurant leftovers and mainly bread for two decades, he was a little reluctant about the vegetables, but munched happily on the grapes we gave him.”

    Mark was slow to explore his snowy new habitat, according to Four Paws. He hadn’t stepped outside a cage in over twenty years. He’ll stay in a smaller outdoor enclosure for the time being until he adjusts to his new environment and moves to a larger enclosure.

    The sanctuary in Arbesbach has operated since 1988, according to its website. Mark will join three other rescued grizzly bears who live on 14,000 square meters of “natural surroundings.”

    “With Mark’s rescue we ended the cruel practice of keeping him next to a restaurant to attract and entertain visitors,” Four Paws’ president Josef Pfabigan said in the release. “We are now one step closer to a world where people treat animals with respect, empathy and understanding.”

  • Cambodia’s Mekong dolphin is dying despite efforts to save it

    Cambodia’s Mekong dolphin is dying despite efforts to save it

    [ad_1]

    The fishing gangs visit the river by night and the rangers do nothing to stop them.

    Working in large groups, the boatmen use fishing methods that have long been outlawed in this part of the Mekong – one of Asia’s mightiest rivers – like gillnetting, which uses nets that hang like a curtain in the water and snag fish by their gills, and electrofishing.

    Normally, the rangers would intervene. But these days they hang back out of a mix of intimidation and sympathy for neighbours made desperate by the pandemic.

    Cambodia’s strict fishing rules, first imposed in 2006, are crucial to the fortunes of the Mekong dolphin, giving the rare but nationally beloved animal a chance at survival after decades of population decline.

    But while dolphin conservation is broadly popular in Cambodia’s poor river communities – and some make money from the visitors they bring – the economic stresses of the pandemic when borders were closed for months forced some into desperate measures to feed their families.

    “We are trying to protect dolphins but criminals are also catching them,” said 63-year-old Sun Koeung, who can earn up to $15 a day from taking people out onto the water to watch the dolphins.

    He says the illegal fishing crews take to the river at 11pm, an hour after the River Guards have completed their shift.

    “If we lose dolphins, no income at all,” he added.

    The illegal activity, hidden in plain sight, helps explain why Mekong dolphin populations are struggling despite nearly two decades of work to support them.

    The Mekong dolphin is a subgroup of the Irrawaddy dolphin, a species found throughout Asia. Its distinctive mouth gives it the appearance of smiling and its intelligence and playfulness have charmed humans for generations. River communities in Laos and Cambodia revere the dolphins as reincarnated ancestors.

    Thousands of these dolphins once lived in the waters of the Mekong, which flows from China down through Myanmar, Thailand, Laos, Cambodia and Vietnam. Today an estimated 89 dolphins in Cambodia are all that remain.

    High death rates, especially among baby dolphins, have conservationists fearing for their future. There is little margin for error as the dolphins only reproduce every two to three years.

    “Back in 2009, we thought we were actually going to make a difference,” said Randall Reeves, a scientist affiliated with the International Union for the Conservation of Nature (IUCN) and an adviser to the Cambodia programme. “I don’t feel we really have.”

    The dolphin’s story is just one of millions that make up the global biodiversity crisis as governments sit down this week to thrash out new biodiversity targets at the long-delayed COP15 in Montreal. Without action a million plant and animal species face extinction within decades, scientists warn.

    However, the recovery of some iconic species, such as bald eagles in the United States, pandas in China and tigers in South Asia show that targeted, politically supported plans can deliver results.

    It was in that spirit that Cambodia and Laos teamed up with the IUCN and the Worldwide Fund for Nature (WWF) to save the Mekong dolphin more than 10 years ago.

    Early conservation efforts

    In Cambodia, the dolphins had a powerful champion in Touch Seang Tana, a career fisheries expert who called them symbols of “national heritage” and made their protection a personal cause.

    Once a rock star in a popular Cambodian band, the colourful Tana rose through the bureaucratic ranks to join the Council of Ministers, the cabinet of Prime Minister Hun Sen.

    In 2006, he assumed a prestigious role, head of Cambodia’s Dolphin Commission, with responsibility for overseeing the recovery plan.

    Tana framed dolphin conservation as a fishing problem and he favoured a stern hand to control it.

    That year, Cambodia banned gill nets in the dolphins’ preferred areas. To enforce the ban, it established the River Guards, a team to patrol the water and confiscate illegal fishing gear. With the help of overseas funding, the team expanded to 72 rangers equipped with motorboats, smartphones, night-vision goggles and a drone.

    By 2017, the measures appeared to be working: The dolphin population had risen from 80 to 92.

    But there were problems, too.

    Some river communities had come to resent the enforcement of the strict rules on fishing in the absence of any attempt to develop alternative livelihoods, said Isabel Beasley, a scientist who began fieldwork on the Mekong dolphin in 1997.

    To feed their families, some bribed the River Guards to look the other way, she said.

    Some even buried the dead dolphins they found, for fear of punishment, according to two former WWF officials.

    According to a joint report by the project partners, the programme failed to record a number of deaths in 2009, 2012 and 2014.

    But in Cambodia’s hierarchical political culture, to point out these issues would have been seen as undermining Tana who insisted the main issue was the gill nets, even as poverty – the root cause of illegal fishing – persisted.

    In an interview with Al Jazeera, Tana said people living in river villages were given tractors and water pumps so they could supplement their incomes with farming.

    “I gave satellite TVs to every village, two to three of them so they can get together to watch media. They were happy,” he said. “You can’t just use regulations and law. You have to strongly do social negotiation, that’s the most important.”

    He accuses foreign NGOs of sometimes exaggerating dolphin deaths and estimated that in 2014, the year he retired, the population was 220.

    He denies dolphin deaths were missed, pointing to strong monitoring by WWF and researchers.

    “NGOs are good. Like WWF,” Tana said. “But the people who work for NGOs are human,” he said. “Some people want to be a big man. ‘I’m the big global NGO or organisation. I have to control everything, you have to follow me.’ No. This I can’t accept.”

    Development is king

    At the Laos-Cambodia border, where the Mekong broadens into a sweeping river pool, the dolphins’ situation was even direr.

    By 2012, this “transboundary” population had fallen to six, a group so small it could only survive through intense protection.

    Lao officials supported dolphins in principle. Lao’s own endangered species list gave Mekong dolphins the highest level of protection under the law.

    But in practice, Lao officials “seemed hesitant to make a commitment” to match Cambodia’s tough fishing controls, said Somany Phay, an official with the Cambodia Fisheries Administration who tried to coordinate strategy with Laos.

    “People in Laos considered it a sensitive issue,” he said.

    The dolphin habitat overlapped with a resource of national interest: energy.

    In 201, Laos approved the Don Sahong dam, a project to send energy to Cambodia. Laos has built dozens of dams as part of a national strategy to export electricity.

    WWF begged Laos to reconsider, saying dam construction would batter the dolphins’ sensitive hearing structures, “almost certainly” killing the last six.

    Regardless, the dam became operational in 2020.

    Last February, WWF-Laos confirmed the death of the last survivor, which some called “Lone George”.

    For some, it was a harsh reminder that while conservation was important, ultimately development was king.

    “They’re proud of the dolphins,” sighed one official involved on the Lao side. “But they won’t put resources into it.” The source declined to be named for fear of repercussions in the closely-controlled country.

    The mystery of the dead dolphins

    While Cambodia’s policies have kept adult dolphins alive, high infant deaths continue to baffle scientists.

    In 2020, eight calves were born but four died, according to a report.

    The dolphins’ typical lifespan is 27-30 years. Of the current population, 70 percent are over 20, according to WWF.

    Over the years, newborn corpses have been found with signs scientists deem ambiguous or even mysterious: skull fractures, blue lesions around the throat and sometimes no visible signs of harm.

    Tooth and tissue samples were sent to labs in the US, dozens of bodies were necropsied and genetics and bacterial cultures were analysed, among the many efforts to solve this mystery.

    None has delivered a clear answer, said Frances Gulland, chair of the US Marine Mammal Commission and a longtime adviser to the Cambodia programme.

    Gulland pointed to small sample sizes – just two to seven specimens a year – and inadequate local infrastructure to receive fresh, undisturbed bodies and analyse them. “These animals are sometimes liquid” by the time they reach the lab, she said.

    Next month she and a small team of scientists will visit Cambodia to shore up lagging aspects of the programme and begin work on a new population estimate.

    But critics say the dolphin project is emblematic of the IUCN’s weaknesses.

    IUCN scientists are unpaid volunteers and they can generally only commit small amounts of time to field visits.

    “What are their achievements? Just workshops,” said Verné Dove, a field veterinarian who participated in the programme from 2006 to 2011 and has just published a dissertation attributing infant deaths to disease.

    “There just comes a time when you have to do something.”

  • Could trawler cams help save world’s dwindling fish stocks?

    Could trawler cams help save world’s dwindling fish stocks?

    [ad_1]

    PORTLAND, Maine — For years, Mark Hager’s job as an observer aboard New England fishing boats made him a marked man, seen as a meddling cop on the ocean, counting and scrutinizing every cod, haddock and flounder to enforce rules and help set crucial quotas.

    On one particularly perilous voyage, he spent 12 days at sea and no crew member uttered even a single word to him.

    Now Hager is working to replace such federally-mandated observers with high-definition cameras affixed to fishing boat masts. From the safety of his office, Hager uses a laptop to watch hours of footage of crew members hauling the day’s catch aboard and measuring it with long sticks marked with thick black lines. And he’s able to zoom in on every fish to verify its size and species, noting whether it is kept or flung overboard in accordance with the law.

    “Once you’ve seen hundreds of thousands of pounds of these species it becomes second nature,” said Hager as he toggled from one fish to another.

    Hager’s Maine-based start-up, New England Maritime Monitoring, is one of a bevy of companies seeking to help commercial vessels comply with new U.S. mandates aimed at protecting dwindling fish stocks. It’s a brisk business as demand for sustainably caught seafood and around-the-clock monitoring has exploded from the Gulf of Alaska to the Straits of Florida.

    But taking the technology overseas, where the vast majority of seafood consumed in the U.S. is caught, is a steep challenge. Only a few countries can match the U.S.′ strict regulatory oversight. And China — the world’s biggest seafood supplier with an ignominious record of illegal fishing — appears unlikely to embrace the fishing equivalent of a police bodycam.

    The result, scientists fear, could be that well-intended initiatives to replenish fish stocks and reduce unintentional bycatch of threatened species like sharks and sea turtles could backfire: By adding to the regulatory burdens already faced by America’s skippers, more fishing could be transferred overseas and further out of view of conservationists and consumers.

    “The challenge now is getting the political will,” said Jamie Gibbon, an environmental scientist at The Pew Charitable Trusts who is leading its efforts to promote electronic monitoring internationally. “We are getting close to the point where the technology is reliable enough that countries are going to have to show whether they are committed or not to transparency and responsible fisheries management.”

    To many advocates, electronic monitoring is something of a silver bullet.

    Since 1970, the world’s fish population has plummeted, to the point that today 35% of commercial stocks are overfished. Meanwhile, an estimated 11% of U.S. seafood imports come from illegal, unreported and unregulated fishing, according to the U.S. International Trade Commission.

    To sustainably manage what’s left, scientists need reliable data on the activities of the tens of thousands of fishing vessels that ply the oceans every day, the vast majority with little supervision.

    Traditional tools like captain’s logbooks and dockside inspections provide limited information. Meanwhile, independent observers — a linchpin in the fight against illegal fishing — are scarce: barely 2,000 globally. In the U.S., the number of trained people willing to take underpaid jobs involving long stretches at sea in an often-dangerous fishing industry has been unable to keep pace with ever-growing demand for bait-to-plate traceability.

    Even when observers are on deck, the data they collect is sometimes skewed.

    A recent study by the National Oceanic and Atmospheric Administration found that when an observer was on deck New England skippers changed their behavior in subtle but important ways that degraded the quality of fisheries data, a phenomenon known as “observer bias.”

    “The fact is human observers are annoying,” Hager said. “Nobody wants them there, and when they aren’t being threatened or bribed, the data they provide is deeply flawed because it’s a proven fact that fishermen behave differently when they’re being watched.”

    Enter electronic monitoring. For as little as $10,000, vessels can be equipped with high-resolution cameras, sensors and other technology capable of providing a safe, reliable look at what was once a giant blind spot. Some setups allow the video to be transmitted by satellite or cellular data back to shore in real time — delivering the sort of transparency that was previously unthinkable.

    “This isn’t your grandfather’s fishery anymore,” said Captain Al Cottone, who recently had cameras installed on his 45-foot groundfish trawler, the Sabrina Maria. “If you’re going to sail, you just turn the cameras on and you go.”

    Despite such advantages, video monitoring has been slow to catch on since its debut in the late 1990s as a pilot program to stop crab overfishing off British Columbia. Only about 1,500 of the world’s 400,000 industrial fishing vessels have installed such monitoring systems. About 600 of those vessels are in the U.S., which has been driving innovation in the field.

    “We’re still in the infancy stages,” said Brett Alger, an official at NOAA charged with rolling out electronic monitoring in the U.S.

    The stakes are especially high in the Western and Central Pacific Ocean — home to the world’s largest tuna fishery. Observer coverage of the Pacific’s longline fleet, which numbers around 100,000 boats, is around 2% — well below the 20% minimum threshold scientists say they need to assess a fish stock’s health. Also, observer coverage has been suspended altogether in the vast region since the start of the coronavirus pandemic, even though the roughly 1 billion hooks placed in the water each year has barely ebbed.

    “Right now we’re flying blind,” said Mark Zimring, an environmental scientist for The Nature Conservancy focused on spreading video monitoring to large-scale fisheries around the world. “We don’t even have the basic science to get the rules of the game right.”

    The lack of internationally-accepted protocols and technical standards has slowed progress for video monitoring, as have the high costs associated with reviewing abundant amounts of footage on shore. Hager says some of those costs will fall as machine learning and artificial intelligence — technology his company is experimenting with — ease the burden on analysts who have to sit through hours of repetitive video.

    Market pressure may also spur faster adoption. Recently, Bangkok-based Thai Union, owner of the Red Lobster restaurants and Chicken of the Sea tuna brand, committed to having 100% “on-the-water” monitoring of its vast tuna supply chain by 2025. Most of that is to come from electronic monitoring.

    But by far the biggest obstacle to a faster rollout internationally is the lack of political will.

    That’s most dramatic on the high seas, the traditionally lawless waters that compromise nearly half the planet. There, the task of managing the public’s resources is left to inter-governmental organizations where decisions are taken based on consensus, so that objections from any single country are tantamount to a veto.

    Of the 13 regional fisheries management organizations in the world, only six require on-board monitoring — observers or cameras — to enforce rules on gear usage, unintentional catches and quotas, according to a 2019 study by the Paris-based Organization for Economic Cooperation and Development, which advises nations on economic policy.

    Among the worst offenders is China. Despite boasting the world’s largest fishing fleet, with at least 3,000 industrial-sized vessels operating internationally, and tens of thousands closer to home, China has fewer than 100 observers. Electronic monitoring consists of just a few pilot programs.

    Unlike in the U.S., where on-water monitoring is used to prepare stock assessments that drive policy, fisheries management in China is more primitive and enforcement of the rules spotty at best.

    Last year, China deployed just two scientists to monitor a few hundred vessels that spent months fishing for squid near the Galapagos Islands. At the same time, it has blocked a widely backed proposal at the South Pacific Regional Fisheries Management Organization to boost observer requirements

    “If they want to do something they definitely can,” said Yong Chen, a fisheries scientist whose lab at Stony Brook University in New York hosts regular exchanges with China. “It’s just a question of priorities.”

    Hazards faced by observers are highest outside U.S. waters, where electronic monitoring is used the least. Sixteen observers have died around the world since 2010, according to the U.S.-based Association for Professional Observers.

    Many of the deaths involve observers from impoverished South Pacific islands working for low pay and with little training and support — even when placed on American-flagged vessels that are subject to federal safety regulations. Such working conditions expose observers to bribery and threats by unscrupulous captains who themselves are under pressure to make every voyage count.

    “It’s in our best interest to have really professional data collection, a safe environment and lots of support from the (U.S.) government,” said Teresa Turk, a former observer who was part of a team of outside experts that in 2017 carried out a comprehensive safety review for NOAA in the aftermath of several observer fatalities.

    Back in the U.S., those who make their living from commercial fishing still view cameras warily as something of a double-edged sword.

    Just ask Scott Taylor.

    His Day Boat Seafood in 2011 became one of the first longline companies in the world to carry an ecolabel from the Marine Stewardship Council — the industry’s gold standard. As part of that sustainability drive, the Fort Pierce, Florida, company blazed a trail for video monitoring that spread throughout the U.S.’ Atlantic tuna fleet.

    “I really believed in it. I thought it was a game changer,” he said.

    But his enthusiasm turned when NOAA used the videos to bring civil charges against him last year for what he says was an accidental case of illegal fishing.

    The bust stems from trips made by four tuna boats managed by Day Boat to a tiny fishing hole bound on all sides by the Bahamas’ exclusive economic zone and a U.S. conservation area off limits to commercial fishing. Evidence reviewed by the AP show that Taylor’s boats were fishing legally inside U.S. waters when they dropped their hooks. But hours later some of the gear, carried by hard-to-predict underwater eddies, drifted a few miles over an invisible line into Bahamian waters.

    Geolocated video footage was essential to proving the government’s case, showing how the boats pulled up 48 fish — swordfish, tuna and mahi mahi — while retrieving their gear in Bahamian waters.

    As a result, NOAA levied a whopping $300,000 fine that almost bankrupted Taylor’s business and has had a chilling effect up and down the East Coast’s tuna fleet.

    When electronic monitoring was getting started a decade ago, it appealed to fishermen who thought that the more reliable data might help the government reopen coastal areas closed to commercial fishing since the 1980s, when the fleet was five times larger. Articles on NOAA’s website promised the technology would be used to monitor tuna stocks with greater precision, not play Big Brother.

    “They had everyone snowballed,” said Martin Scanlon, a New York-based skipper who heads the Blue Water Fishermen’s Association, which represents the fleet of around 90 longline vessels. “Never once did they mention it would be used as a compliance tool.”

    Meanwhile, for Taylor, his two-year fight with the federal government has cost him dearly. He’s had to lay off workers, lease out boats and can no longer afford the licensing fee for the ecolabel he worked so hard to get. Most painful of all, he’s abandoned his dream of one day passing the fishing business on to his children.

    “The technology today is incredibly effective,” Taylor said. “But until foreign competitors are held to the same high standards, the only impact from all this invasiveness will be to put the American commercial fishermen out of business.”

  • Tagovailoa, Zaporizhzhia make list of most mangled words

    Tagovailoa, Zaporizhzhia make list of most mangled words

    [ad_1]

    BOSTON — “Miami Dolphins quarterback Tua Tagovailoa explained the significance of the Chicxulub impact crater to actor Domhnall Gleeson over a drink of negroni sbagliato in the Ukrainian city of Zaporizhzhia,” is the kind of sentence that just might tie your tongue up in knots.

    It contains five examples from this year’s list of the most mispronounced words released Wednesday by The Captioning Group, which since 1991 has captioned and subtitled real-time events on television in the U.S. and Canada.

    The Captioning Group has compiled the list since 2016 by surveying the words and names most often mangled on live television by newsreaders, politicians, public figures and others. It is commissioned by Babbel, the online language learning company based in New York and Berlin.

    Yes, the list is a little humorous, but it’s also educational and highlights how some of the biggest international news events of the year have entered the North American consciousness, said Esteban Touma, a senior content producer and language teacher at Babbel.

    “It really shows the ways we interact with other languages and really gives a good grasp of what’s going on in the world and how we connect with people abroad,” he said.

    Don’t be intimidated by tough-to-pronounce words, he said. It is an opportunity to learn. After all, even professionals sometimes have problems.

    “People want to get the right pronunciation but it’s hard to do so,” he said.

    Just ask Joe Biden.

    New British Prime Minister Rishi Sunak was infamously referred to as “Rasheed Sanook” by the U.S. president, but he wasn’t the only one to stumble over the name, which should be pronounced REE-shee SOO-nahk.

    Then there’s Grammy-winning singer Adele, who informed the world in October that her fans have for years been mispronouncing her name. It’s not “ah-DELL” but “uh-DALE.”

    The other words on the list, with phonetic pronunciations provided by Babbel, were:

    — Chicxulub (CHICK-choo-loob) — The crater in the Gulf of Mexico caused by the asteroid that scientists say likely caused the extinction of the dinosaurs was in the news recently.

    — Domhnall Gleeson (DOH-null GLEE-sun) — The Irish actor called out talk show host Stephen Colbert for mispronouncing his first name.

    — Edinburgh (ed-in-BRUH) — American news anchors faced criticism for mispronouncing the Scottish capital during coverage of Queen Elizabeth II’s memorial in September.

    — Negroni sbagliato (ne-GRO-nee spah-lee-AH-toh) — The alcoholic beverage was introduced to the world by actor Emma D’Arcy, whose social media mention of the drink received more than 14 million views.

    — Novak Djokovic (NO-vak JO-kuh-vich) — The Serbian tennis star was in the news in January when he was barred from competing in the Australian Open and deported for failing to comply with the nation’s COVID-19 vaccination rules.

    — Ohtani rule (oh-TAHN-ee) — Major League Baseball’s rule named after 2021 AL MVP Shohei Ohtani allows a starting pitcher to remain in a game as the designated hitter even after leaving the mound.

    — Tuanigamanuolepola (Tua) Tagovailoa (TOO-uh-ning-uh-mah-noo-oh-LEH-po-luh TUNG-o-vai-LOH-uh) — The Miami Dolphins quarterback became the center of discussion about NFL concussion protocols after suffering injuries in consecutive games.

    — Zaporizhzhia (zah-POH-reezha) — The Ukrainian city is the location of Europe’s largest nuclear power plant, which was shut down in September as the nation’s war with Russia raged in the area.

  • 1,700 dead seals found on Russia’s Caspian coast

    1,700 dead seals found on Russia’s Caspian coast

    [ad_1]

    MOSCOW — About 1,700 seals have been found dead on the Caspian Sea coast in southern Russia, officials said Sunday.

    The authorities in the Russian province of Dagestan said that it’s still unclear what caused the animals’ deaths, but they likely died of natural reasons.

    Regional officials initially said Saturday that 700 dead seals were found on the coast, but on Sunday Zaur Gapizov, head of the Caspian Environmental Protection Center, said according to the state RIA Novosti news agency that after a broader inspection of the coast the number of dead animals was 1,700.

    Gapizov said the seals likely died a couple of weeks ago. He added that there was no sign that they were killed by poachers.

    Experts of the Federal Fisheries Agency and prosecutors inspected the coastline and collected data for laboratory research, which didn’t immediately spot any pollutants.

    Several previous incidents of mass deaths of seals were attributed to natural causes.

    The data about the number of seals in the Caspian varies widely. The fisheries agency has said the overall number of Caspian seals is 270,000-300,000, while Gapizov’s center put the number at 70,000.

  • Nevada toad in geothermal power fight gets endangered status

    Nevada toad in geothermal power fight gets endangered status

    [ad_1]

    RENO, Nev. (AP) — A tiny Nevada toad at the center of a legal battle over a geothermal power project has officially been declared an endangered species, after U.S. wildlife officials temporarily listed it on a rarely used emergency basis last spring.

    “This ruling makes final the listing of the Dixie Valley toad, ” the U.S. Fish and Wildlife Service said in a formal rule published Friday in the Federal Register.

    The spectacled, quarter-sized amphibian “is currently at risk of extinction throughout its range primarily due to the approval and commencement of geothermal development,” the service said.

    Other threats to the toad include groundwater pumping, agriculture, climate change, disease and predation from bullfrogs.

    The temporary listing in April marked only the second time in 20 years the agency had taken such emergency action.

    Environmentalists who first petitioned for the listing in 2017 filed a lawsuit in January to block construction of the geothermal power plant on the edge of the wetlands where the toad lives about 100 miles (160 kilometers) east of Reno — the only place it’s known to exist on earth.

    “We’re pleased that the Biden administration is taking this essential step to prevent the extinction of an irreplaceable piece of Nevada’s special biodiversity,” said Patrick Donnelly, Great Basin regional director for the Center for Biological Diversity.

    The center and a tribe fighting the project say pumping hot water from beneath the earth’s surface to generate carbon-free power would adversely affect levels and temperatures of surface water critical to the toad’s survival and sacred to the Fallon Paiute-Shoshone Tribe.

    The Fish and Wildlife Service cited those concerns in the final listing rule.

    “The best available information indicates that a complete reduction in spring flow and significant reduction of water temperature are plausible outcomes of the geothermal project, and these conditions could result in the species no longer persisting,” the agency said.

    “Because the species occurs in only one spring system and has not experienced habitat changes of the magnitude or pace projected, it may have low potential to adapt to a fast-changing environment,” it said. “We find that threatened species status is not appropriate because the threat of extinction is imminent.”

    Officials for the Reno-based developer, Ormat Technology, said the service’s decision was “not unexpected” given the emergency listing in April. In recent months, the company has been working with the agency and the U.S. Bureau of Land Management to modify the project to increase mitigation for the toad and reduce any threat to its survival.

    The lawsuit over the original plan to build two power plants capable of producing 60MW of electricity is currently before U.S. District Judge Robert Jones in Reno. It’s already has made one trip to the 9th U.S. Circuit Court of Appeals, which refused in August to grant a temporary injunction blocking construction of the power plant the bureau approved in December 2021.

    But just hours after that ruling, Ormat announced it had agreed to temporarily suspend all work on the project until next year. Then in late October, the bureau and Ormat asked the judge to put the case on hold while Ormat submitted a new plan to build just one geothermal plant, at least for now, that would produce only 12MW of power.

    Ormat Vice President Paul Thomsen said in an email to The Associated Press on Thursday that the company disagrees with the wildlife service’s “characterization of the potential impacts” of its project as a basis for the listing decision. He said it doesn’t change the ongoing coordination and consultation already under way to minimize and mitigate any of those impacts “regardless of its status under the Endangered Species Act.”

    “Following the emergency listing decision, BLM began consultation with the FWS, and Ormat has sought approval of a smaller project authorization that would provide additional assurances that the species will not be jeopardized by geothermal development,” he said.

    “As a zero-emissions, renewable energy facility, the project will further the Biden administration’s clean energy initiatives and support the fight against climate change,” Thomsen said.

    Donnelly agreed renewable energy is “essential to combating the climate emergency.”

    “But it can’t come at the cost of extinction,” he said.

    The last time endangered species protection first was initiated on an emergency basis was in 2011, when the Obama administration took action on the Miami blue butterfly in southern Florida. Before that, an emergency listing was granted for the California tiger salamander under the Bush administration in 2002.

    Other species listed as endangered on an emergency basis over the years include the California bighorn sheep in the Sierra Nevada in 1999, Steller sea lions in 1990, and the Sacramento River winter migration run of chinook salmon and Mojave desert tortoise, both in 1989.
