PFAS ‘forever chemicals’ harming wildlife the world over: Study
- While the health impacts of toxic per- and polyfluoroalkyl chemicals, or PFAS, are well known in humans, a new study reports how they affect a wide range of wildlife species.
- In this survey of published studies, the authors found and mapped wildlife exposures worldwide, including impacts on animal species in remote parts of the planet, including the Arctic.
- Researchers documented serious PFAS-triggered conditions in wildlife, including suppressed immunity, liver damage, developmental and reproductive issues, nervous and endocrine system impacts, gut microbiome/bowel disease and more. PFAS pose yet another threat to already beleaguered global wildlife.
- National governments have done little to restrict use of PFAS or remediate pollution, despite growing evidence of increased harm to both humans and wildlife. The study authors call for immediate action to remediate PFAS-contamination sites and regulate industrial chemicals to help protect threatened and endangered species.

Global study of 71,000 animal species finds 48% are declining
- A new study evaluating the conservation status of 71,000 animal species has shown a huge disparity between “winners” and “losers.” Globally, 48% of species are decreasing, 49% remain stable, and just 3% are rising. Most losses are concentrated in the tropics.
- Extinctions skyrocketed worldwide with the onset of the Industrial Revolution, especially since World War II, when resource extraction and consumption rates soared, and the planet saw exponential growth in human population to 8 billion by 2022.
- Habitat destruction, especially in the tropics, is the major driver. But a confluence of human activities, ranging from climate change, to wildlife trafficking, hunting, invasive species, pollution and other causes, are combining to drive animal declines.
- The research also revealed that one-third of non-endangered species are in decline. These data, say the researchers, could provide an early warning for preemptive conservation action by spotlighting species slipping downhill, but where there’s still time to act — and prevent extinction.

Kew Gardens joins local partners to save tropical plants from extinction
- The U.K.’s Kew Gardens does far more than preserve and display 50,000 living and 7 million preserved specimens of the world’s plants; it also educates the public about the importance of plant conservation via its famous London facility.
- In 2022, Kew Gardens identified 90 plants and 24 fungi completely new to science. They include the world’s largest giant water lily, with leaves more than 3 meters across, from Bolivia; and a 15-meter tree from Central America, named after the murdered Honduran environmental activist Berta Cáceres.
- The institution is working actively with local partners in many parts of the world, and especially in the tropics, to save these species in-situ, that is, where they were found. When Kew can’t do this, it saves seeds in its herbarium, carrying out ex-situ conservation.
- Kew researchers, along with scientists from tropical nations, are also working together to ensure that local communities benefit from this conservation work. The intention is to save these threatened plants for the long term, helping slow the pace of Earth’s current extinction crisis — the only one caused by humans.

In search of Taiwan’s lost clouded leopards, anthropology uncovers more than camera traps (commentary)
- Indigenous folklore says that the Taiwan’s — likely extinct — clouded leopard species led two human brothers to a heavenly place 600 years ago.
- While biologists have searched extensively for the animal in recent years using camera traps and other modern means, better clues to this enigmatic creature can perhaps be found by consulting Taiwan’s Indigenous people.
- Whether Taiwan’s clouded leopards are extinct or not, its forests could support a population of up to 600 individuals if reintroduced from elsewhere in the region.

Cats, charisma and climate change (commentary)
- Delegates are meeting later this week at the United Nations Climate Change Conference to the debate the future of life on Earth as we know it, through the lens of how to take action on climate change.
- Jonathan Ayers, Chair of the Board of Directors for wild cat conversation organization Panthera, makes a case for expanding efforts beyond combatting climate change: Addressing the global extinction crisis.
- “For far too long, the crisis of biodiversity loss has been largely overlooked and deprioritized,” Ayers writes. “If we are to earnestly protect the planet, environmental dialogue and focus must shift to one in which the climate change and biodiversity conservation crises are regarded and funded as two sides of the same coin.” Ayers says that cats are a great place to start when it comes to conserving ecosystems and staving off extinction.

Seed dispersal is just as important as pollination (commentary)
- Why does it seem like conservationists only care about pollination, and the creatures like bees that do it?
- Seed dispersal is every bit as important, and to ensure a future with the greatest plant diversity, we should focus effort on conserving the animal groups known for this activity, known as ‘zoochory.’

The Pope, a prince and a judge walk into a bar…to argue for nature’s rights (commentary)
- It sounds like the beginning of a bad joke, but Pope Francis, Prince Charles, and judges around the world are now supporting the rights of nature.
- The belief that nature was something to be both feared and conquered provided legitimacy for the enactment of laws that authorized the domination and destruction of nature by the Western world.
- Today, the growing movement for the rights of nature is in its nascent stages but the outcome could help humanity onto a much more sustainable path.

Podcast: Two tunas and a tale of managed extinction
- On this episode of the Mongabay Newscast, we take a look at the tales of two tuna: yellowfin tuna in the Indian Ocean, and bluefin tuna in the Atlantic.
- Mongabay staff writer Malavika Vyawahare tells us about the series of articles she wrote looking at how EU-controlled fleets dominate the annual yellowfin tuna haul in the Indian Ocean, and how that impacts developing island nations like Seychelles.
- We also speak with author Jen Telesca about her recent book Red Gold: The Managed Extinction of Giant Bluefin Tuna, which details how, under the watch of the International Commission for the Conservation of Atlantic Tunas, the Atlantic bluefin tuna has become such a prized catch that it’s being driven to extinction.

Study warns of ‘biotic annihilation’ driven by hunting, habitat destruction
- Humans are driving wildlife to extinction 1,000 times faster than the natural rate, robbing the planet not just of species but also of functional and phylogenetic diversity, the authors of a new paper argue.
- Different kinds of human activities affect biodiversity differently, with hunting having the largest impact on terrestrial mammals, the research found.
- Millions of years of evolution are encoded into species that coexist with humans today; to lose them is also to lose that biological heritage.
- The research maps out the relationship between species richness and functional and phylogenetic loss for individual countries to aid national-level policymaking.

The riddle of Madagascar’s megafauna extinction just got trickier
- Madagascar saw a relatively recent mass extinction event about 1,000 years ago, when gorilla-sized lemurs, towering elephant birds, and grand tortoises were all wiped out from the island.
- A recently published paper complicates the widely-held understanding that humans were to blame for the crash, by drawing attention to a megadrought that the authors say also played a role.
- The new study uses geological evidence from Madagascar and Rodrigues, an island now part of Mauritius about 1,600 kilometers (1,000 miles) east of Madagascar, to construct a climatic record.
- Some scientists have questioned whether the geological record from Madagascar paints an accurate picture of past climate, or whether the data from Rodrigues can shed light on conditions in Madagascar.

Biologists warn ‘extinction denial’ is the latest anti-science conspiracy theory
- There’s a growing refusal by some groups to acknowledge the ongoing global extinction crisis being driven by human actions, conservation scientists say.
- These views are pushed by many of the same people who also downplay the impacts of climate change, and go against the actual evidence of widespread species population declines and recent extinctions.
- Scientists say this phenomenon will likely spike again this week, since a major Convention on Biological Diversity report is due to be released.
- The authors of a new report on extinction denial advise experts to proactively challenge its occurrence, and present the “cold hard scientific facts.”

Less than a thousand remain: New list of animals on the brink of extinction
- More than 500 vertebrate species are on the brink of extinction, with populations of fewer than a thousand individuals, a new study says.
- According to the authors, the Earth is experiencing its sixth mass extinction, extinction rates accelerating, and human activity is to blame.
- The authors call the ongoing extinction perhaps “the most serious environmental threat to the persistence of civilization, because it is irreversible.”
- “The conservation of endangered species should be elevated to a national and global emergency for governments and institutions, equal to climate disruption to which it is linked,” they say.

Update to biodiversity treaty proposes protecting at least 30% of Earth
- Global policymakers have proposed extending protections to at least 30% of terrestrial, marine and freshwater ecosystems around the world.
- The coming decade of biodiversity protection looks to borrow from the Paris climate agreement by setting targets for protecting intact ecosystems, curbing the spread of invasive species, and halving pollution from organic and plastic waste.
- For biodiversity hotspots, the Convention on Biological Diversity (CBD) calls for safeguarding 60% of these areas by bringing them under the protected area framework or other management mechanisms.
- Some groups have questioned whether offering protection to 30% of areas and strict protection to only 10% will be enough to curb the alarming loss of biodiversity being witnessed globally.

Time is running out for Southeast Asia
- Several species and subspecies have gone extinct in the last 100 years. Others remain missing.
- Most of Southeast Asia’s large-bodied animals are now threatened with extinction.
- Deforestation and the wildlife trade have even left smaller-bodied species decimated as well.
- Southeast Asia has to decide if preserving its irreplaceable and unique wildlife is a priority – or the losses will continue to mount.

Heat stress is causing desert bird populations to collapse
- Sites in the Mojave Desert in the western U.S. surveyed by ecologists a century ago have lost an average of 43 percent of their breeding bird species.
- New research suggests higher temperatures have increased the daily water needs of birds, which could decimate their populations if climate change worsens.
- The most vulnerable birds are larger, carnivorous species such as turkey vultures and prairie falcons that get most of their water from prey.

Why you should care about the current wave of mass extinctions (commentary)
- The extinction crisis we are witnessing is only the beginning of a wave of mass ecocide of non-human life on Earth, a process that could wipe out a million species of plants and ani-mals from our planet in the short term (read: decades). About 15 thousand scientific studies (!) support this terrifying conclusion, as it can be read in the assessment report produced by the independent UN Intergovernmental Science-Policy Platform for Biodiversity and Ecosy-stem Services (IPBES).
- Certainly this is not what I dreamed of as a child in love with nature and wildlife. But how could I have ever imagined back then, in the 1970s, that during my first 50 years of life the global human population would literally double? That the global economy would increase four-fold, and that in parallel — and not by coincidence — wildlife populations would drop by a staggering 60 percent globally? How could I have ever imagined back then that I would personally witness and document, as a field conservationist, actual extinctions on the ground?
- In order to create a critical mass of awareness globally, there is still an important question to answer: Why should we care to conserve what is left of wild ecosystems and species of our planet? This is a question we should be ready to answer clearly, especially considering that most of the world population currently lives in urban centers, remains quite unaware of eco-logical matters, and is disconnected from nature — and therefore can’t fully appreciate how much our survival as a species is still deeply dependent on ecosystems and nature.

The climate crisis and the pain of losing what we love (commentary)
- World leaders came to the UN last week to decisively tackle climate change again. “This is not a negotiation summit because we don’t negotiate with nature. This is a Climate Action Summit!” declared the UN Secretary-General. But again, global leaders failed and committed to carbon cuts that fall far short of curbing catastrophe.
- In doing so, our leaders committed us to an escalating global environmental crisis that is already unleashing vast changes across Earth’s ecosystems — with many sweeping alterations charted by our scientists, but many other local shifts and absences only noted by those who observe and cherish wild things.
- The loss of familiar weather patterns, plants and animals (from monarchs to native bees) and an invasion of opportunistic living things (Japanese knotweed to Asian longhorned ticks) can foster feelings of vertigo — of being a stranger in a strange land — emotions, so personal and rubbing so raw, they can be hard to describe.
- So I’ve tried to express my own feelings for one place, Vermont, my home, that is today seeing rapid change. At the end of this piece, Mongabay invites you to tally your own natural losses. We’ll share your responses in a later story. This post is a commentary. Views expressed are those of the author, not necessarily Mongabay.

Wilderness cuts the risk of extinction for species in half
- Wilderness areas buffer species against the risk of extinction, reducing it by more than half, a new study shows.
- Places with lots of unique species and wilderness with the last remaining sections of good habitat for certain species had a more pronounced impact on extinction risk.
- The authors contend that safeguarding the last wild places should be a conservation priority alongside the protection and restoration of heavily impacted “hotspots.”

As the mammal tree of life suffers hits, should we prioritize which species to save?
- More than 300 mammal species have gone extinct since shortly before the last ice age, a loss of more than 2.5 billion years of evolutionary history across all ancestral lines, a sweeping study reports.
- Even in the best-case scenario — we completely stop climate change and extinctions within 50 years — evolution would need at least three million years to redevelop that lost biodiversity.
- Choosing to save the most distinct at-risk species is one way to minimize ongoing damage to the mammal tree of life.

Map pinpoints ‘last chance’ locations of endangered species
- A new assessment updates the last known ranges for nearly 1,500 species of animals and plants at 853 locations around the world.
- The three-year effort is aimed at helping scientists, governments and conservationists identify the threats that could lead to the extinction of these species and find ways to address them.
- Governments are already using this information to identify target areas for conservation to protect the last remaining habitats of threatened species.
- Nearly half of the sites identified lack formal protection, despite many of them having been flagged as important more than a decade ago.

Scientists urge world leaders to scale up ambitions to protect global biodiversity
- Research has shown that a sixth mass extinction event is underway and largely driven by human activities. With the global population set to balloon to 10 billion people by 2050, which will more than double the current demand for food and water, scientists are increasingly calling for mankind to set aside sufficient amounts of ecosystems on land and at sea to ensure the survival of the many species with which we share planet Earth.
- Yet, according to Jonathan Baillie, Executive Vice President and Chief Scientist of the National Geographic Society, and Ya-Ping Zhang, Vice President of the Chinese Academy of Sciences, “Current levels of protection do not even come close to the required levels.”
- To preserve global biodiversity and safeguard the provision of critical ecosystem services, ambitions must be ratcheted up in 2020, when the world’s governments will meet at the Convention on Biological Diversity in Beijing, China to set biodiversity targets for the future, Baillie and Zhang argue.

The tropics are in trouble, warn scientists
- Plants and animals in the tropics are threatened by a range of issues, warn researchers writing in the journal Nature.
- The tropics are facing a mélange of well-documented human-driven threats: destruction of forests and marine ecosystems, overexploitation by the likes of industrial fishing fleets and commercial hunters, the spread of diseases and invasive species, and the growing impacts of climate change, which stress both ecosystems and their inhabitants.
- These threats aren’t likely to diminish soon. Human population continues to rise, but growing affluence means that it is increasingly outpaced by resource consumption, which acts a multiplier in terms of humanity’s planetary footprint.
- To stave off this bleak future, the researchers call for “major improvements in local and global governance capacity and a step-change in how environmental objectives are integrated into broader development goals.”

Biomass study finds people are wiping out wild mammals
- A team of scientists mined previous studies for estimates of the total mass of carbon found in each group of organisms on Earth as a way to measure relative biomass.
- Plants house some 450 gigatons of the 550 gigatons — or about 80 percent — of the carbon found in all of Earth’s life-forms, the team found, and bacteria account for another 15 percent.
- Humans represent just a hundredth of a percent of the Earth’s biomass, but we’ve driven down the biomass of land animals by 85 percent and marine mammals by about 80 percent since the beginning of the last major extinction about 50,000 years ago.

Humans are leaving their mark on the world’s protected areas, study finds
- About one-third of the world’s total protected area — around 6 million square kilometers (2.3 million square miles) — bears the scars of substantial degradation at the hands of humans, according to research published in the journal Science.
- The researchers found that large parks and reserves held to the toughest standards are doing significantly better than those with laxer controls.
- The authors argue that assessments of the effectiveness of protected areas should be considered, especially as governments try to meet one of the Aichi Biodiversity Targets calling for protecting 17 percent of the Earth’s land area by 2020.

More than 40 percent of Madagascar’s freshwater life sliding toward extinction, IUCN finds
- In an assessment of 653 freshwater plant and animal species living on Madagascar and nearby islands, biologists found that 43 percent are threatened with extinction or there isn’t enough information to assess how well they’re doing.
- Nearly 80 percent of endemic plants examined in the study face extinction.
- The team lists unsustainable farming practices, deforestation, dam construction, mining and the overuse of natural resources, such as overfishing, as causes for the widespread declines.

‘Photo Ark’ a quest to document global biodiversity: Q&A with photographer Joel Sartore and director Chun-Wei Yi
- The film “RARE: Creatures of the Photo Ark” follows National Geographic photographer Joel Sartore as he travels the world snapping pictures of thousands of different animal species.
- In the last 12 years, Sartore has photographed nearly 8,000 species.
- “RARE: Creatures of the Photo Ark” was named Best Conservation Film at the New York WILD Film Festival.

Seychelles home to new species of caecilian, a legless amphibian
- The Petite Praslin caecilian (Hypogeophis pti) is the world’s newest — and possibly the smallest — caecilian, a type of legless amphibian.
- Scientists discovered the animal on the island of Praslin in the Seychelles, an archipelago in the Indian Ocean.
- The new species is the seventh caecilian species found in the Seychelles, where the amphibians have been evolving for 64 million years.

North America’s ash trees, Africa’s antelopes face heightened threat of extinction
- The latest update to the International Union for the Conservation of Nature’s (IUCN) Red List of Threatened Species, released today, finds that even species once considered so abundant as to be safe have been put at risk of extinction by human activities and their impacts on the environment.
- Five of the six most widespread and valuable ash tree species in North America have declined so severely due to an invasive beetle that they have now been entered onto the Red List as Critically Endangered, the last threat level before extinction in the wild.
- Five African antelopes also had their threat status upgraded in the latest Red List update, among them the Giant Eland (Tragelaphus derbianus), previously listed as Least Concern but now Vulnerable, and the Mountain Reedbuck (Redunca fulvorufula), also previously listed as Least Concern but now assessed as Endangered.

The world’s first biotacide (commentary)
- Many refer to it as the Sixth Mass Extinction, but it isn’t. It’s different.
- We are not simply in the sixth round of a continuing series of events that have devastated life on Earth. We are in the midst of the first of a new type of event, unlike the earlier mass extinction events.
- The five mass extinctions were naturally occurring cataclysmic events that completely changed the course of evolution and life on Earth. The current event is a ‘biotacide,’ an unnatural cataclysmic event that is changing the course of life on Earth.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Sixth mass extinction ‘tsunami’ coming, but preventable
- Biologist Thomas Lovejoy writes in the Proceedings of the National Academy of Sciences that we can stop the current spate of biodiversity and species loss that the Earth is experiencing.
- Pointing to a recent study showing that many animals are declining in numbers in addition to those facing the imminent risk of extinction, Lovejoy argues that we need to address all of the impacts that humans have on ecosystems.
- He calls for the restoration of degraded forests and wetlands — activities in which everyone can participate — to facilitate the movement of wildlife between habitats and bring back the services that ecosystems provide.

Audio: Global megadam activism and the sounds of nature in Taiwan
- Activists from around the world attended the conference to strategize around stopping what they see as destructive hydropower projects. As Bardeen relates in her commentary, many attendees at the conference have faced harassment, intimidation, and worse for their opposition to dam projects, but they’re still standing strong in defense of free-flowing rivers.
- We also speak with Yannick Dauby, a French sound artist based in Taiwan. Since 2002, Dauby has been crafting sound art out of field recordings made throughout the small country of Taiwan and posting them on his website, Kalerne.net.
- In this Field Notes segment, Dauby plays a recording of his favorite singer, a frog named Rhacophorus moltrechti; the sounds of the marine life of the corals of Penghu, which he is documenting together with biologists; the calls bats use to echolocate (slowed down 16 times so they can be heard by human ears!); and more!
- All that plus the top news on this episode of the Mongabay Newscast!

Ongoing mass extinction causing ‘biological annihilation,’ new study says
- Building on research in which they showed that two species have gone extinct per year over the past century, a team of biologists analyzed the population trends for 27,600 vertebrates around the world.
- They found that nearly a third of the animals they looked at were on the decline.
- In a closer look at 177 well-studied mammals, the team found that all had lost 30 percent or more of their home ranges, and 40 percent had lost at least 80 percent of their habitat.

Research suggests less affluent countries more dedicated to wildlife conservation than rich countries
- A team of researchers with Oxford University’s Wildlife Conservation Research Unit (WildCRU) and non-profit conservation organization Panthera looked at 152 countries and compiled what they call a Megafauna Conservation Index in order to evaluate each country’s contributions to the conservation of the world’s biodiversity.
- African countries Botswana, Namibia, Tanzania and Zimbabwe, together with South Asian nation Bhutan, were the top five megafauna conservation performers, the researchers found.
- Norway came in at sixth, the top-ranked developed country, followed by Canada, which came in at eighth. The United States ranked nineteenth, lower than countries like Malawi and Mozambique that are among the least-developed in the world.

‘Crunch time for biodiversity’: Farming, hunting push thousands of species toward extinction
- Eighty percent of threatened animals are losing ground – literally, in the form of habitat loss – to agriculture.
- Up to 50 percent of threatened birds and mammals face extinction at the hands of hunters.
- In a study published in the journal Nature, a team of scientists explores solutions to avoid destroying the habitats of these animals, such as increasing yields in the developed world and minimizing fertilizer use.

Study finds hundreds of thousands of tropical species at risk of extinction due to deforestation
- Scientists have long believed that the rate at which we are destroying tropical forests, and the habitat those forests represent, could drive a global mass extinction event, but the extent of the potential losses has never been fully understood.
- John Alroy, a professor of biological sciences at Australia’s Macquarie University, examined local-scale ecological data in order to forecast potential global extinction rates and found that hundreds of thousands of species are at risk if humans disturb all pristine forests remaining in the tropics.
- Mass extinction will occur primarily in tropical forests because Earth’s terrestrial biodiversity is so heavily concentrated in those ecosystems, Alroy notes in the study.

Extinct mammoths and rhinos portend a grim future in a warming climate
- The new analysis shows that, while hunting caused problems for cold-dwelling rhinos and mammoths, and in some cases drove them from certain areas completely, the changing climate ultimately led to their extinction.
- Hunting pressure also eradicated some species of horses, but others, such as wild horses (E. przewalskii) and donkeys (E. asinus), were able to survive.
- Along with deer, these mammals probably survived because of their smaller sizes, increased mobility and higher reproductive rates than either mammoths or rhinos.
- With just a 1-degree Celsius rise in Earth’s temperature per century, we could see the same rise in temperatures over the next 500-1,000 years that took 10,000-15,000 years at the end of the last ice age.

How humans create as well as destroy species
- The effect of human activity on the natural world is profound, and if we want to gain a complete understanding of how it is altering the biosphere, then examining speciation is important.
- We know that speciation does exist, and so does human-induced speciation. If we want to use biodiversity as a measure of our impact on the biosphere, then surely speciation needs to be considered.
- Speciation can occur rapidly, and is not necessarily slower than extinction, so it is certainly relevant.

Here Are The Top 15 Environmental Stories of 2015
- This was a year that saw President Obama reject the Keystone pipeline as historic droughts and a vicious wildfire season wracked the western US and Canada.
- The world committed to climate action in Paris as Southeast Asia was choking on the worst Indonesian haze in years.
- Shell aborted its plans to drill in the Arctic for the “foreseeable” future and ExxonMobil is being investigated for lying to the public about climate risks.

Biologist finds “we are on pace to create a mass extinction” of frogs worldwide
- John Alroy, a professor of biology at Australia’s Macquarie University, says “a runaway train of extinction is now likely to produce what would be seen as a global mass extinction.”
- A large majority of the 200 extinct frog species were probably lost in the past few decades, just as extinctions and severe population crashes began accelerating in the 1970s and 1980s.
- The current extinction rate for frogs is four orders of magnitude higher than the long-term background average, Alroy found.

Unanimous agreement among scientists: Earth to suffer major loss in species

The thylacine, the dodo, the great auk, the passenger pigeon, the golden toad: these species have become symbols of extinction. But they are only the tip of the recent extinction crisis, and according to a survey of 583 conservation scientists, they are only the beginning. In a new survey in Conservation Biology, 99.5 percent of […]
Over 900 species added to endangered list during past year

Previously unpublished 17th Century Dutch sketch of the dodo, taken from a real specimen, either alive or stuffed. Dronte means dodo in Dutch. The past twelve months have seen 914 species added to the threatened list by the world’s authority of species endangerment, the International Union for the Conservation of Nature (IUCN)’s Red List. Over […]
