(08/09/2010) The International Union for the Conservation of Nature (IUCN) and Conservation International (CI) have sent teams of researchers to 14 countries on five continents to search for the world's lost frogs. These are amphibian species that have not been seen for years—in some cases even up to a century—but may still survive in the wild. Amphibians worldwide are currently undergoing an extinction crisis. While amphibians struggle to survive against habitat loss, climate change, pollution, and overexploitation, they are also being wiped out by a fungal disease known as chytridiomycosis.
Scientists hunt for 'lost frogs' around the globe
(08/09/2010) From now through October, teams of scientists will be scouring through leaf litters, in shallow pools, under rocks, and in tree trunks for the world's 'lost frogs'. Searching in 14 countries on five continents, the researchers are looking for some 100 species of frogs that have not been seen in decades and in some cases up to a century. While some of the species may well be extinct, researchers are holding out hope that they can find the ones that are still hanging on, albeit by a thread.
Forgotten species: the nameless giant forest snail
(08/04/2010) All species known to science are granted a Latin name. While this naming system is beneficent to researchers, Latin names—sad to say—don't really capture the public's attention anymore. Fortunately most species also have common names—the red fox, the pileated woodpecker, the Asian elephant, and so on. Some of these names even end up being quite wonderful: like the dusky dolphin (love the alliteration), the strawberry poison dart frog (points for creativity), the blobfish (if you see a photo you'll know why), and my all-time favorite: the goliath bird-eating spider. Although this name is slightly redundant (any spider that eats birds is goliath), I wouldn't change it for anything. However, some species, especially those less 'charismatic' ones, never get beyond their Latin name. Such is the fate of a giant forest snail known to researchers as Archachatina bicarinata and to the rest of us as...well nameless. But this begs a question: how do we save a species if we don't even name it?
Cameroon says goodbye to cheetahs and African wild dogs
(07/28/2010) Researchers have confirmed that cheetahs (Acinonyx jubatus) and African wild dogs (Lycaon pictus) have become essentially extinct in Cameroon. A three year study by the Institute of Environmental Sciences at Leiden University in the Netherlands found that the same factors that pushed cheetahs and African wild dogs to local extinction, have also left Cameroon's other big predators hanging by a thread, including the lion, the leopard, and two species of hyena: the spotted and the striped.
Already illegal, one man tests poisoning rhino horn too
(07/28/2010) Given the epidemic of rhino poaching across Africa and Asia, which has placed four out of five species in jeopardy of extinction, one fed-up game manager wants to take the fight beyond the poachers to the consumer. Ed Hern, owner of the Lion and Rhino Park near Johannesburg, told South Africa's The Times that he has begun working with a veterinarian on injecting poison into a rhino's horn to consumers. He told The Times that people who consumed poisoned rhino horn "would get very sick or die".
Coral reefs doomed by climate change
(07/22/2010) The world's coral reefs are in great danger from dual threats of rising temperatures and ocean acidification, Charlie Veron, Former Chief Scientist of the Australian Institute of Marine Science, told scientists attending the Association for Tropical Biology and Conservation meeting in Sanur, Bali. Tracing the geological history of coral reefs over hundreds of millions of years, Veron said reefs lead a boom-and-bust existence, which appears to be correlated with atmospheric carbon dioxide levels. With CO2 emissions rising sharply from human activities, reefs—which are home to perhaps a quarter of marine species and provide critical protection for coastlines—are poised for a 'bust' on a scale unlike anything seen in tens of millions of years.
Following public outcry, New Zealand drops plan to mine protected areas
(07/20/2010) The New Zealand government has caved to public pressure, announcing that it is dropping all plans to mine in protected areas. The plan to open 7,000 hectares of protected areas to mining would have threatened a number of rare and endemic species, including two frogs that are prehistoric relics virtually unchanged from amphibian fossils 150 million years old: Archey's frog (Leiopelma archeyi) and Hochstetter's frog (Leiopelma hochstetteri).
30 frog species, including 5 unknown to science, killed off by amphibian plague in Panama
(07/19/2010) With advanced genetic techniques, researchers have drawn a picture of just how devastating the currently extinction crisis for the world's amphibians has become in a new study published in the Proceedings of the Nation Academy of Sciences (PNAS). Studying frog populations using DNA barcoding in Panama's Omar Torrijos National Park located in El Copé researchers found that 25 known species and 5 unknown species have vanished since 1998. None have returned.
Australian mammals in steady decline even in large National Park
(07/19/2010) Kakadu National Park, one of the Australia's "largest and best-resourced" protected areas, is experiencing a staggering decline in its small mammal population, according to a new study published in Wildlife Research. Spanning nearly 2 million hectares—larger than Fiji—the park lies in tropical northern Australia. 'This decline is catastrophic,' John Woinarski, lead author of the study and expert on Australian mammals, told mongabay.com. 'We know of no comparable case in the world of such rapid and severe decline of a large proportion of native species in a large conservation reserve.'
Forgotten species: the cryptic Jerdon's courser
(07/06/2010) According to my Oxford English Dictionary, 'cryptic' means: 'secret, mystical; mysterious; obscure in meaning; enigmatic'. This is the perfect adjective for the rare Indian bird, Jerdon's courser (Rhinoptilus bitorquatus). 'It is not so easy to spot as it is a small bird and when you show the torch it crouches and merges with the surroundings. So we need very good trained eyes to look for them,' Dr. P. Jeganathan recently told mongabay.com.
Elle MacPherson promotes consumption of illegal rhino horn [warning: graphic image]
(07/02/2010) Despite a number of scientific studies showing that rhino horn has no curative properties, supermodel, entrepreneur, and recent host of Britain's Next Top Model, Elle Macpherson, says she ingests powdered rhino horn because: '[it] works for me'. In an interview with The Sunday Times via Twitter, Elle Macpherson says the illegal substance tastes like 'crushed bone and fungus'.
Photos: rats drive island lizard to extinction
(06/29/2010) The Selmunett lizard (Podarcis filfolensis ssp. Kieselbachi) is very likely extinct, according to Maltese naturalist Arnold Sciberras. One of four subspecies of the Maltese wall lizard, the Selmunett lizard was last seen in 2005. Although the lizard's home—Selmunett Island—has long been uninhabited by people, that fact did not help save the lizard. Over-predation by introduced rats is thought to be the primary cause of lizard's extinction.
To save species, Malaysia implements daring plan to trap wild Bornean rhino
(06/13/2010) With less than 40 individuals left in the world, the Bornean rhino is a small step away from extinction. Yet conservationists and government officials in the Malaysian state of Sabah are not letting this subspecies of the Sumatran rhino go without a fight. Implementing a daring last-ditch plan to save the animal, officials are working to capture a wild female to mate with a fertile male named Tam, who was rescued after wandering injured into a palm oil plantation two years ago.
Study points to global snake decline
(06/09/2010) A number of reports over the last decade have shown amphibians, lizards, fish, and birds facing steep population declines across species and continents, providing further evidence that the planet is undergoing a mass extinction. Now a new study in Biology Letters adds another group of animals to that list: snakes.
Quota filled, bluefin tuna hunt ends early
(06/09/2010) The European Commission (EC) has announced an early end to the Atlantic bluefin tuna season since the quota of 13,500 tons has been met. The fishing will end at 11:59 tonight GMT.
Already on the edge, lemurs could become victims of climate change
(06/08/2010) Expanding beyond well-known victims such as polar bears and coral reefs, the list is growing of species likely to be hard hit by climate change: from lizards to birds to amphibians. Now a new study has uncovered another group of species vulnerable to a warmer world: lemurs.
Will we ever know the full wildlife toll of the BP oil spill?
(06/08/2010) Will we ever know the full wildlife toll of the BP oil spill? The short answer: no. The gruesome photos that are making the media rounds over the last week of oiled birds, fish, and crustaceans are according to experts only a small symbol of the ecological catastrophe that is likely occurring both in shallow and deep waters. Due to the photos, birds, especially the brown pelican, have become the symbol of the spill to date. But while dozens of birds have been brought to rescue stations covered in oil, the vast majority will die out at sea far from human eyes and snapping cameras, according to Sharon Taylor a vet with the US Fish and Wildlife Service.
The bluefin tuna wars: Greenpeace and Sea Shepherd step up tactics to save Critically Endangered species
(06/07/2010) Things have become ugly in the Mediterranean: over the weekend, fishermen and Greenpeace activists squared off over the fate of the Critically Endangered bluefin tuna. One run-in, in which Greenpeace worked to free tuna from fishermen's nets, left one activist in the hospital after a fisherman sunk a hook in the activist's leg. Meanwhile, the Sea Shepherd Conservation Society has announced a 'Blue Rage' campaign that will target illegal fishing of bluefin tuna.
Two new frogs discovered in Panama amidst amphibian plague
(06/06/2010) Researchers working to save Panama's frogs from a fatal disease have stumbled on two species unknown to science. In Omar Torrijos National Park they found a bigger version of a common species, which is now known to be a unique species, and near the Colombian border they discovered a new frog that has been named after Spanish for DNA. Both frogs were discovered while researchers searched for frog populations in chytridiomycosis-infected areas. The highly contagious disease chytridiomycosis has devastated frog species worldwide and is believe to be at least in part responsible for some 100 extinctions of amphibians.
'No hope now remains' for the Alaotra grebe
(05/31/2010) World governments have missed their goal of stemming biodiversity loss by this year, instead biodiversity loss has worsened according to scientists and policy-makers, and a little rusty-colored bird, the Alaotra grebe (Tachybaptus rufolavatus) is perhaps a victim of this failure to prioritize biodiversity conservation. Native to a small region in Madagascar, the grebe has been declared extinct by BirdLife International and the IUCN Red List due to several factors including the introduction of invasive carnivorous fish and the use of nylon gill-nets by local fishermen, which now cover much of the bird's habitat, and are thought to have drowned diving grebes. The bird was also poached for food.
Researchers: Madagascar rosewoods deserve CITES protection
(05/27/2010) A new policy paper in Science warns that several species of Madagascar's rosewood could be pushed to extinction due to a current illegal logging crisis on the island. These hardwood species should be considered for protection under Convention of International Trade in Endangered Species of Wild Fauna and Flora (CITES), the researchers conclude.
18,225 new species discovered in 2008
(05/27/2010) In the 2010 State of Observed Species researchers have announced that 18,225 living species were discovered in 2008. In addition, 2,140 new extinct species were discovered byway of fossils.
World's 'number one frog' faces extinction from New Zealand government
(05/26/2010) Archey's frog is a survivor: virtually unchanged evolutionarily for 150 million years, the species has survived the comet that decimated the dinosaurs, the Ice Age, and the splitting of continents. Seventy million years ago New Zealand broke away from Australia, essentially isolating Archey's frog and its relatives from all predatory mammals. Yet, if the New Zealand government has its way this species may not survive the century, let alone the next few decades. The New Zealand government has put forward a controversial proposal to begin opening three of the nation's protected areas to mining: Great Barrier Island, Paparoa National Park, and Coromandel Peninsula where the last populations of Archey's frogs live. According to critics, the government's proposal could push Archey's frog toward extinction, while negatively impacting a number of other endangered species, beloved wild lands, and a nation driven by tourism.
Children prioritize TV, video games over saving the environment
(05/18/2010) When asked to rank what was most important to them children across the world chose watching TV and playing video games ahead of saving the environment, according to an Airbus survey of 10,000 children, ages 5-18, from ten countries. Forty percent of children ranked watching TV and playing video games as most important to them, while 4 percent put 'saving the environment' as number one. Nine percent of the children said that protecting animals was most important to them.
Climate change devastating lizards worldwide: 20 percent estimated to face extinction
(05/13/2010) Lizards have evolved a variety of methods to escape predators: some will drop their tail if caught, many have coloring and patterning that blends in with their environment, a few have the ability to change their colors as their background changes, while a lot of them depend on bursts of speed to skitter away, but how does a lizard escape climate change? According to a new study in Science they don't. The study finds that lizards are suffering local extinctions worldwide due exclusively to warmer temperatures. The researchers conclude that climate change could push 20 percent of the world's lizards to extinction within 70 years.
A nation of tragedies: the unseen elephant wars of Chad
(05/12/2010) Stephanie Vergniault, head of SOS Elephants in Chad, says she has seen more beheaded corpses of elephants in her life than living animals. In the central African nation, against the backdrop of a vast human tragedy—poverty, hunger, violence, and hundreds of thousands of refugees—elephants are quietly vanishing at an astounding rate. One-by-one they fall to well-organized, well-funded, and heavily-armed poaching militias. Soon Stephanie Vergniault believes there may be no elephants left. A lawyer, screenwriter, and conservationist, Vergniault is a true Renaissance-woman. She first came to Chad to work with the government on electoral assistance, but in 2009 after seeing the dire situation of the nation's elephants she created SOS Elephants, an organization determined to save these animals from local extinction.
Collapsing biodiversity is a 'wake-up call for humanity'
(05/10/2010) A joint report released today by the Convention on Biological Diversity (CBD) and the UN Environment Program (UNEP) finds that our natural support systems are on the verge of collapsing unless radical changes are made to preserve the world's biodiversity. Executive Secretary of the Convention on Biological Diversity, Ahmed Djoghlaf, called the bleak report "a wake-up call for humanity."
How an agricultural revolution could save the world's biodiversity, an interview with Ivette Perfecto
(05/04/2010) Most people who are trying to change the world stick to one area, for example they might either work to preserve biodiversity in rainforests or do social justice with poor farmers. But Dr. Ivette Perfecto was never satisfied with having to choose between helping people or preserving nature. Professor of Ecology and Natural Resources at the University of Michigan and co-author of the recent book Nature’s Matrix: The Link between Agriculture, Conservation and Food Sovereignty, Perfecto has, as she says, "combined her passions" to understand how agriculture can benefit both farmers and biodiversity—if done right.
Despite promises, world governments failing to save biodiversity
(04/29/2010) In 2002 world leaders committed to reducing the global rate of biodiversity loss within eight years time: 2010. While many have noted that world governments have largely failed on their promises, a new study in Science looks at the situation empirically and agrees that their has been no significant reduction in biodiversity loss and, at the same time, pressures on the world's species have risen, not fallen.
Video: Madagascar could become "Haiti-like"
(04/28/2010) Niall O'Connor from the World Wildlife Fund warns in a Carte Blanche production that if the ecological destruction of Madagascar continues, the poor island country could become "Haiti-like", where he says, "most of the biodiversity, most of the forests are gone".
A day to celebrate (and save) the world's amphibians: the 2nd Annual Save the Frogs Day
(04/28/2010) Friday, April 30th is for the frogs: educational programs, conservation walks with experts, frog leaping races, and the world's first protest to save frogs are all planned for the world's 2nd Annual Save the Frogs Day. Organized by the non-profit SAVE THE FROGS!, events are so far planned in 15 countries on every continent besides Antarctica—fittingly the only continent that lacks amphibians.
Photo: monster worm is less than a monster
(04/28/2010) Some places have Loch Ness and Bigfoot, but the Palouse prairie of the western United States has the giant Palouse earthworm. Reported to stretch 3 feet long, spit, and—even more strangely—smell like lilies, the earthworm has become apart of the region's folklore and has only been seen a few times since the 1980s leading to concerns that it was gravely endangered and maybe even extinct.
World failing on every environmental issue: an op-ed for Earth Day
(04/22/2010) The biodiversity crisis, the climate crisis, the deforestation crisis: we are living in an age when environmental issues have moved from regional problems to global ones. A generation or two before ours and one might speak of saving the beauty of Northern California; conserving a single species—say the white rhino—from extinction; or preserving an ecological region like the Amazon. That was a different age. Today we speak of preserving world biodiversity, of saving the 'lungs of the planet', of mitigating global climate change. No longer are humans over-reaching in just one region, but we are overreaching the whole planet, stretching ecological systems to a breaking point. While we are aware of the issues that threaten the well-being of life on this planet, including our own, how are we progressing on solutions?
Turning to the matrix: a more accurate way to predict extinction
(04/14/2010) According to most conservationists the globe is striding into the midst of the Sixth Mass Extinction. Species populations worldwide are dropping and in many cases species are vanishing all together due to pollution, climate change, poaching and hunting, overconsumption, invasive species, and exotic diseases, but no threat proves more pervasive and devastating for the world's species than habitat loss.
Environmentalists say President of Philippines not deserving of conservation award
(04/13/2010) Filipino environmentalists and religious leaders have expressed shock and anger that Gloria Macapagal-Arroyo, the President of the Philippines, has been chosen to receive a conservation award from the US Congress in Washington, DC today according to the Philippine Daily Enquirer.
Jane Goodall renews her faith in nature and humanity during the "Gombe 50" anniversary, An interview with Dr. Jane Goodall
(04/12/2010) 2010 marks a monumental milestone for the Jane Goodall Institute (JGI) and its founder, Dr. Jane Goodall, DBE. Fifty years ago, Goodall, who is today a world-renowned global conservation leader, first set foot on the shores of Lake Tanganyika, in what is now Tanzania’s Gombe National Park. The chimpanzee behavioral research she pioneered at Gombe has produced a wealth of scientific discovery, and her vision has expanded into a global mission 'to empower people to make a difference for all living things.' Time, however, has not stood still for Gombe. The wild chimps of the area have suffered as the local human population has swelled. Gombe National Park is now a forest fragment, a 35-square-kilometer island of habitat isolated in a sea of subsistence farming. Because the problems facing Gombe—unsustainable land practices, overpopulation, and a cycle of poverty—are typical of many other areas, lessons learned by Dr. Goodall and her team provide valuable insights for solutions at Gombe and beyond.
Once common tortoise from Madagascar will be 'extinct in 20 years'
(04/05/2010) The radiated tortoise, once common throughout Madagascar, faces extinction within the next 20 years due to poaching for its meat and the illegal pet trade, according to biologists with the Turtle Survival Alliance (TSA) and the Wildlife Conservation Society (WCS). Returning from field surveys in southern Madagascar's spiny forest, they found regions without a single turtle. Locals said that armed bands of poachers were taking truckloads of tortoises to be sold in meat markets. The tortoise is also popular in the underground pet trade, although it is protected by CITES (Convention on International Trade in Endangered Species).
History repeats itself: the path to extinction is still paved with greed and waste
(04/05/2010) As a child I read about the near-extinction of the American bison. Once the dominant species on America's Great Plains, I remember books illustrating how train-travelers would set their guns on open windows and shoot down bison by the hundreds as the locomotive sped through what was left of the wild west. The American bison plunged from an estimated 30 million to a few hundred at the opening of the 20th century. When I read about the bison's demise I remember thinking, with the characteristic superiority of a child, how such a thing could never happen today, that society has, in a word, 'progressed'. Grown-up now, the world has made me wiser: last month the international organization CITES (Convention on International Trade in Endangered Species) struck down a ban on the Critically Endangered Atlantic bluefin tuna. The story of the Atlantic bluefin tuna is a long and mostly irrational one—that is if one looks at the Atlantic bluefin from a scientific, ecologic, moral, or common-sense perspective.
Seed dispersal in the face of climate change, an interview with Arndt Hampe
(04/05/2010) Without seed dispersal plants could not survive. Seed dispersal, i.e. birds spreading seeds or wind carrying seeds, means the mechanism by which a seed is moved from its parent tree to a new area; if fortunate the seed will sprout in its new resting place, produce a plant which will eventually seed, and the process will begin anew. But in the face of vast human changes—including deforestation, urbanization, agriculture, and pasture lands, as well as the rising specter of climate change, researchers wonder how plants will survive, let alone thrive, in the future?
What happened to China?: the nation's environmental woes and its future
(04/01/2010) China has long been an example of what not to do to achieve environmentally sustainability. Ranking 133rd out of 146 countries in 2005 for environmental performance, China faces major environmental problems including severe air and water pollution, deforestation, water-issues, desertification, extinction, and overpopulation. A new article in Science discusses the complex issues that have led to China's environmental woes, and where the nation can go to from here.
Sumatran rhino loses pregnancy: conservationists saddened but remain resolute
(03/31/2010) Rhino conservationists' hopes were dampened today by news that Ratu, a female Sumatran rhino, had lost her pregnancy. Just months after the announcement of the pregnancy—the first at Indonesia’s Sumatran Rhino Sanctuary in Way Kambas National Park—Ratu lost the embryo. Still, say conservationists, the very fact that Ratu became pregnant at all should keep hope alive for the beleaguered species.
Finding forest for the endangered golden-headed lion tamarin
(03/29/2010) Brazil's golden-headed lion tamarin is a small primate with a black body and a bright mane of gold and orange. Listed as Endangered by the IUCN Red List, the golden-headed lion tamarin (Leontopithecus chrysomelas) survives in only a single protected reserve in the largely degraded Atlantic Forest in Brazil. Otherwise its habitat lies in unprotected patches and fragments threatened by urbanization and agricultural expansion. Currently, a natural gas pipeline is being built through prime tamarin habitat.
Scientists discover world's first amphibious insects: Hawaiian caterpillars
(03/22/2010) Scientists have never before discovered a truly amphibious insect until now: writing in the Proceedings of the National Academy of Sciences researchers have announced the discovery of 12 species of Hyposmocoma moths in the Hawaiian islands which they consider truly amphibious—that is a species able to survive both on land and underwater indefinitely.
The Asian Animal Crisis
(03/18/2010) The United Nation declared 2010 as the International Year of Biodiversity (IYB). One of the goals of the IYB is to celebrate the achievements of the Convention of Biological Diversity signed by 192 countries since 1992. But what have we accomplished since 1992? Did we put an end to biodiversity loss? The truth is that there is not much to celebrate at all. Asia is a perfect example where the animal crisis and the loss of biodiversity have worsened over decades. The first question that should come to mind is: how many species have vanished in Asia because of human activities? Records of recently extinct species in Asia show 71 species that have disappeared in the wild. Examples include the Yunnan lake newt (Cynops wolterstorffi) from China, the Bonin thrush (Zoothera terrestris) from Japan, or the redtailed black shark (Epalzeorhynchos bicolor) from Thailand.
Forgotten Species: the marooned pygmy three-toed sloth
(03/16/2010) Many people consider tropical islands mini-paradises: sanctuaries cut-off from the rest of the world. Some species flourish on islands for the same reason. With few predators and a largely consistent environment, once a species has comfortably adapted to its habitat there's little to do but thrive. That is until something changes: like humans showing up. Changes in confined island ecosystems often have large and rapid impacts, too fast and too big for marooned species to survive.
Extinction outpaces evolution
(03/09/2010) Extinctions are currently outpacing the capacity for new species to evolve, according to Simon Stuart, chair of the Species Survival Commission for the International Union for the Conservation of Nature (IUCN).
Frog in Australia goes from 'extinct' to very, very endangered
(03/08/2010) Facing habitat loss, pollution, climate change, and the devastating chytrid fungus, there has been little positive news about amphibians recently. However, a story out of Australia brings a much needed respite from bad news. In 2008 Luke Pearce, a fisheries conservation officer, stumbled on a frog that had been thought to be extinct for over thirty years. Not recorded since the 1970s, Pearce rediscovered the yellow-spotted bell frog (Litoria castanea) on rural Australian farmland in the Southern Tableland of New South Wales.
Why seed dispersers matter, an interview with Pierre-Michel Forget, chair of the FSD International Symposium
(03/07/2010) There are few areas of research in tropical biology more exciting and more important than seed dispersal. Seed dispersal—the process by which seeds are spread from parent trees to new sprouting ground—underpins the ecology of forests worldwide. In temperate forests, seeds are often spread by wind and water, though sometimes by animals such as squirrels and birds. But in the tropics the emphasis is far heavier on the latter, as Dr. Pierre-Michel Forget explains to mongabay.com. "[In rainforests] a majority of plants, trees, lianas, epiphytes, and herbs, are dispersed by fruit-eating animals. […] As seed size varies from tiny seeds less than one millimetres to several centimetres in length or diameter, then, a variety of animals is required to disperse such a continuum and variety of seed size, the smaller being transported by ants and dung beetles, the larger swallowed by cassowary, tapir and elephant, for instance."
Photos: Madagascar's wonderful and wild frogs, an interview with Sahonagasy
(03/03/2010) To save Madagascar's embattled and beautiful amphibians, scientists are turning to the web. A new site built by herpetologists, Sahonagasy, is dedicated to gathering and providing information about Madagascar's unique amphibians in a bid to save them from the growing threat of extinction. "The past 20 years have seen resources wasted because of a poor coordination of efforts," explains Miguel Vences, herpetologist and professor at the Technical University of Braunschweig. "Many surveys and reports have been produced that were never published, many tourists found and photographed amphibians but these photos were not made available to mapping projects, many studies carried out by Malagasy students did not make use of literature because it was not available."
Common pesticide changes male frogs into females, likely devastating populations
(03/01/2010) One of the world's most popular pesticides, atrazine, chemically castrates male frogs and in some instances changes them into completely functionally females, according to a new study in the Proceedings of the National Academy of Sciences. The authors conclude that atrazine likely plays a large, but unsuspected role in the current global amphibian crisis.
