(03/05/2014) The term marsupial frog sound like a hoax, but, believe it or not, it's real. Recently, herpetologists welcomed a new species, known as Gastrotheca dysprosita and described in the journal Phyllomedusa. Unlike mammal marsupials, which typically carry their young in pouches on their torsos and are found primarily in Australia, the Gastrotheca genus of frogs, which contains 62 species, is found in the Andes region on South America and sport their pouches on their backs (also called a "dorsal brood pouch").
287 amphibian and reptile species in Peruvian park sets world record (photos)
(01/28/2014) It's official: Manu National Park in Peru has the highest diversity of reptiles and amphibians in the world. Surveys of the park, which extends from high Andean cloud forests down into the tropical rainforest of the Western Amazon, and its buffer zone turned up 155 amphibian and 132 reptile species, 16 more than the 271 species documented in Ecuador's Yasuní National Park in 2010.
New frog species discovered on tallest mountain in Indochina
(01/22/2014) A team of Australian and Vietnamese researchers recently discovered a new species of frog in the high elevations of Vietnam’s Mount Fansipan, according to a new paper in Zootaxa. The amphibian was named Botsford’s leaf-litter frog (Leptolalax botsfordi) as a tribute to Christopher Botsford for his role in amphibian biodiversity research in Asia.
High-living frogs hurt by remote oil roads in the Amazon
(01/14/2014) Often touted as low-impact, remote oil roads in the Amazon are, in fact, having a large impact on frogs living in flowers in the upper canopy, according to a new paper published in PLOS ONE. In Ecuador's Yasuni National Park, massive bromeliads grow on tall tropical trees high in the canopy and may contain up to four liters of standing water. Lounging inside this micro-pools, researchers find a wide diversity of life, including various species of frogs. However, despite these frogs living as high as 50 meters above the forest floor, a new study finds that proximity to oil roads actually decreases the populations of high-living frogs.
Not seen in over 130 years, 'extinct' frog rediscovered in Sri Lanka
(01/10/2014) In 1876—the same year that the first telephone call was made—the British scientist Albert Günther described a new species of frog from Sri Lanka, but the species, known as the webless shrub frog (Pseudophilautus hypomelas), was never seen again. Having disappeared into history, scientists considered the species extinct—that is until a 2010 expedition stumbled on 40 mystery frogs.
Sky islands: exploring East Africa's last frontier
(12/04/2013) The montane rainforests of East Africa are little-known to the global public. The Amazon and Congo loom much larger in our minds, while the savannas of East Africa remain the iconic ecosystems for the region. However these ancient, biodiverse forests—sitting on the tops of mountains rising from the African savanna—are home to some remarkable species, many found only in a single forest. A team of international scientists—Michele Menegon, Fabio Pupin, and Simon Loader—have made it their mission to document the little-known reptiles and amphibians in these so-called sky islands, many of which are highly imperiled.
Microhabitats could buffer some rainforest animals against climate change
(11/25/2013) As temperatures increase worldwide due to anthropogenic climate change, scientists are scrambling to figure out if species will be able to survive rapidly warming ecosystems. A new study in Global Change Biology offers a little hope. Studying reptiles and amphibians in the Philippines, scientists say some of these species may be able to seek refuge in cooler microhabitats, such as tree holes or under the soil, in order to stay alive during intensifying heatwaves. But, the scientists' stress, the shelter from microhabitats can only protect so far.
Strange mouth-brooding frog driven to extinction by disease
(11/21/2013) An unusual species of mouth-brooding frog was likely driven to extinction by the fungus Batrachochytrium dendrobatidis (Bd), making an unusual example of 'extinction by infection', argue scientists writing in the open-access journal PLOS ONE. Rhinoderma rufum has not been seen in the wild since 1980.
Thought-to-be-extinct 'halloween' frog rediscovered in Costa Rica
(11/04/2013) A breeding population of a critically endangered harlequin toad thought to be extinct in Costa Rica has been discovered in a tract of highland forest in the Central American country, reports a paper published in Amphibia-Reptilia. Atelopus varius, an orange-and-black harlequin toad, was once relatively common from central Costa Rica to western Panama. But beginning in the 1980's the species experienced a rapid population collapse across most of its range.
New to science: 2 lizards, 1 frog discovered on Australian expedition (pictures)
(10/28/2013) Researchers from James Cook University and National Geographic discovered three new herp species — a cryptic leaf-tail gecko, a colorful skink, and a frog — during an expedition to northeastern Australia. The species are described in three papers published in October in the journal Zootaxa.
Small invertebrates could be key to uncovering the mysteries of killer amphibian fungus
(10/22/2013) In 2004, the first-ever Global Amphibian Assessment (GAA) reviewed all 5,743 amphibian species known to science and concluded that 32% were threatened with extinction - a number far exceeding corresponding figures for birds and mammals (12 to 23% respectively). In addition to the usual culprits of climate change and habitat destruction, a startling 92.5% of amphibians listed as Critically Endangered were found to be undergoing enigmatic declines linked to an unexpected perpetrator - the chytrid fungus, Batrachochytrium dendrobatidis (Bd).
Scientists discover cocoa frog and 60 other new species in remote Suriname (photos)
(10/11/2013) In one of the most untouched and remote rainforests in the world, scientists have discovered some sixty new species, including a chocolate-colored frog and a super-mini dung beetle. The species were uncovered in Southeastern Suriname during a Rapid Assessment Program (RAP); run by Conservation International (CI), RAPS involve sending teams of specialists into little-known ecosystems to record as much biodiversity as they can in a short time. In this case, sixteen researchers from around the world had about three weeks to document the region's biodiversity.
Amphibians evolve resistance to popular pesticide
(10/04/2013) Rachel Carson and, more recently, Sandra Steingraber have successfully drawn popular attention to the risks of pesticides on wildlife. Many of the environmental consequences of pesticides have now been well documented by scientists; however, studies investigating the evolutionary consequences of pesticides on non-target species are largely missing. Not surprisingly, most studies looking at how species evolve in response to pesticide-use have been on target species such as mosquitoes and crop pests, which show that some target species have evolved resistance to common pesticides.
Photo essay: India's Western Ghats is a haven for endemic amphibians
(09/16/2013) The Western Ghats are a globally recognized repository of biological diversity for our planet. We know very little about most species found here, particularly the ecologically sensitive and spectacularly beautiful 179 amphibians. Astonishingly, 87% of all Western Ghats frogs are endemic and found nowhere else on the planet. Our collaborative research project with Drs Paul Robbins and Ashwini Chhatre examining biodiversity in production landscapes of Ghats unearthed some spectacular amphibians in 2013.
Global warming may ‘flatten’ rainforests
(09/12/2013) Climate change may push canopy-dwelling plants and animals out of the tree-tops due to rising temperatures and drier conditions, argues a new study published in Proceedings of the Royal Society B. The development may be akin to 'flattening' the tiered vegetation structure that characterizes the rainforest ecosystem.
New poison dart frog discovered in 'Lost World'
(07/19/2013) Scientists have described a new species of poison dart frog after discovering it during a study to determine the impact of tourism on biodiversity in a tract of rainforest known as 'The Lost World' in Guyana.
Vocal-sac breeding frog possibly extinct
(07/02/2013) Somewhere in the wet pine forests of Chile, a male frog is gulping-up a bunch of eggs. No he's not eating them, he's just being a good dad. Darwin's frogs are known for their unique parenting-style: tadpoles are incubated in the vocal sac of the father. First recorded by Charles Darwin during his world famous voyage aboard the Beagle, the amphibians were common in the native Chilean pine forests until the last few decades. Now, scientists believe that one of the two species, the northern Darwin's frog (Rhinoderma rufum), may have vanished for good. And the other is hanging on by a thread.
Amazonian students help monitor threatened frog populations
(07/01/2013) According to the International Union for Conservation of Nature, amphibians are the most threatened group of animals on Earth: currently around 30 percent of the world's amphibians are listed as threatened with extinction. However this percentage doesn't include those species about which too little is known to evaluate (26 percent). Amphibians face many threats but two of the largest are habitat loss and the lethal chytrid fungus, which has rapidly spread worldwide and is likely responsible for numerous extinctions. But conservationists are coming up with innovative and creative ways to keep amphibians from disappearing, including a program from the Detroit Zoological Society (DZS) that is working with students in the Peruvian Amazon to monitor frog populations.
Palm oil expansion endangering rare frogs in Malaysia
(06/04/2013) Expansion of the palm oil industry in Malaysia is destroying key habitat for endangered frogs, putting them at greater risk, finds a new study published in the journal Conservation Biology.
Turning up the temperature might save frogs' lives
(05/28/2013) Over the past 30 years, amphibians worldwide have been infected with a lethal skin disease known as the amphibian chytrid fungus (Batrachochytrium dendrobatidis). "The disease can cause rapid mortality, with infected frogs of susceptible species dying within weeks of infection in the laboratory." Jodi Rowley, a herpetologist with the Australian Museum told mongabay.com. "This disease has now been associated with declines and extinctions in hundreds of species of amphibians worldwide, and is a serious threat to global amphibian biodiversity."
Two new frog genera discovered in India's Western Ghats, but restricted to threatened swamp-ecosystems
(04/22/2013) The misty mountains of the Western Ghats seem to unravel new secrets the more you explore it. Researchers have discovered two new frog genera, possibly restricted to rare and threatened freshwater swamps in the southern Western Ghats of India. The discoveries, described in the open-access journal Zootaxa, prove once again the importance of the mountain range as a biodiversity hotspot.
Saviors or villains: controversy erupts as New Zealand plans to drop poison over Critically Endangered frog habitat
(04/10/2013) New Zealand's Department of Conservation (DOC) is facing a backlash over plans to aerially drop a controversial poison, known as 1080, over the habitat of two endangered, prehistoric, and truly bizarre frog species, Archey's and Hochsetter's frogs, on Mount Moehau. Used in New Zealand to kill populations of invasive mammals, such as rats and the Australian long-tailed possum, 1080 has become an increasingly emotive issue in New Zealand, not just splitting the government and environmentalists, but environmental groups among themselves. Critics allege that the poison, for which there is no antidote, decimates local animals as well as invasives, while proponents say the drops are the best way to control invasive mammals that kill endangered species like birds and frogs and may spread bovine tuberculosis (TB).
Scientists discover 8 new frogs in one sanctuary, nearly all Critically Endangered (photos)
(03/21/2013) Two surveys in the mountainous forests of Sri Lanka's Peak Wilderness Sanctuary have uncovered eight new species of frogs, according to a massive new paper in the Journal of Threatened Taxa. While every year over a hundred new amphibians are discovered, eight new discoveries in a single park is especially notable. Sri Lanka is an amphibian-lovers paradise with well over 100 described species, most of which are endemic, i.e. found only on the small island country. Unfortunately the country has also seen more frog extinctions than anywhere else, and seven of the eight new species are already thought to be Critically Endangered.
Scientists clone extinct frog that births young from its mouth
(03/18/2013) Australian scientists have produced cloned embryos of an extinct species of frog known for its strange reproductive behavior, reports the University of New South Wales.
Captive frogs may be spreading diseases to wild cousins across Southeast Asia
(03/07/2013) Scientists have documented a series of links between exotic frogs for trade and diseases in wild frogs in Southeast Asia, including the first documented case of the chytrid fungus—a virulent and lethal disease—in Singapore. According to researchers writing in a new study in EcoHealth, frogs imported into Southeast Asia as pets, food, or traditional medicine are very likely spreading diseases to wild populations.
Starry frog rediscovered after thought extinct for 160 years (photos)
(03/07/2013) In 1853 Edward Frederick Kelaart, a physician and naturalist, collected a strange frog on the island of Sri Lanka then a British colony known as Ceylon. The specimen was a large shrub frog (about 2 inches or 5.5 centimeters long) with black-outlined white specks on lime-green skin. He dubbed it "starry" after its pale specks, but that was last anyone heard of it. Even the holotype—the body of the amphibian collected by Kelaart—went missing. Fast forward nearly 160 years—two world wars, Sri Lanka's independence, and a man on the moon—when a recent expedition into Sri Lanka's Peak Wilderness rediscovered a beguiling frog with pinkish specks.
Frogs radio-tracked for first time in Madagascar
(03/01/2013) Researchers have radio-tracked frogs for the first time in Madagascar. Attaching tiny radio transmitters weighing 0.3-0.35 grams (1/100 of an ounce) to 36 rainbow frogs (Scaphiophryne gottlebei), the research team tracked the movement of the colorful frogs through rugged canyons in Madagascar's Isalo Massif. They found that the frogs have a short breeding period that occurs after the first intense rainfall at the start of the rainy season.
Popular pesticides kill frogs outright
(01/28/2013) Commonly used agrochemicals (pesticides, fungicides and herbicides) kill frogs outright when sprayed on fields even when used at recommended dosages, according to new research in Scientific Reports. Testing seven chemicals on European common frogs (Rana temporaria), the scientists found that all of them were potentially lethal to amphibians. In fact, two fungicides—Headline and Captain Omya—wiped out the entire population of frogs at the recommended dosage. The study warns that agricultural chemicals could be having a large-scale and largely unrecorded impact on the world's vanishing amphibians.
Common toads ravaged by killer disease in Portugal
(01/14/2013) The chytrid fungus—responsible for millions of amphibian deaths worldwide—is now believed to be behind a sudden decline in the common midwife toad (Alytes obstetricans), according to a new paper in Animal Conservation. Researchers have detected the presence of the deadly fungus in the Serra da Estrela, north-central Portugal, home to a population of the midwife toad.
New giant flying frog discovered near city of 9 million
(01/09/2013) Jodi Rowley is no stranger to discovering new amphibians—she's helped describe over 10 in her short career thus far—but still she was shocked to discover a new species of flying frog less than 100 kilometers from a major, bustling Southeast Asian metropolis, Ho Chi Minh City. Unfortunately, the new frog, dubbed Helen's tree frog (Rhacophorus helenae), may be on the verge of extinction, according to the description published in the Journal of Herpetology.
New rare frog discovered in Sri Lanka, but left wholly unprotected
(11/05/2012) Sri Lanka, an island country lying off the southeast coast of India, has long been noted for its vast array of biodiversity. Islands in general are renowned for their weird and wonderful creatures, including high percentages of endemic species—and Sri Lanka, where scientists recently discovered a new frog species, is no exception.
Artificial 'misting system' allows vanished toad to be released back into the wild
(11/01/2012) In 1996 scientists discovered a new species of dwarf toad: the Kihansi spray toad (Nectophrynoides asperginis). Although surviving on only two hectares near the Kihansi Gorge in Tanzania, the toads proved populous: around 17,000 individuals crowded the smallest known habitat of any vertebrate, living happily off the moist micro-habitat created by spray from adjacent waterfalls. Eight years later and the Kihansi spray toad was gone. Disease combined with the construction of a hydroelectric dam ended the toads' limited, but fecund, reign.
Tiny new frog discovered in India bypasses the free-swimming tadpole stage
(09/07/2012) A tiny new frog species has been discovered in the rainforests of India's Western Ghats.
Private reserve safeguards newly discovered frogs in Ecuadorian cloud forest
(08/28/2012) Although it covers only 430 hectares (1,063 acres) of the little-known Chocó forest in Ecuador, the private reserve las Gralarias in Ecuador is home to an incredible explosion of life. Long known as a birder's paradise, the Reserva las Gralarias is now making a name for itself as a hotspot for new and endangered amphibians, as well as hundreds of stunning species of butterfly and moth. This is because the reserve is set in the perfect place for evolution to run wild: cloud forest spanning vast elevational shifts. "The pacific slope cloud forests [...] are among the most endangered habitats in the world," explains Reserva las Gralarias' founder, Jane Lyons, in a recent interview with mongabay.com.
Climate change may be worsening impacts of killer frog disease
(08/13/2012) Climate change, which is spawning more extreme temperatures variations worldwide, may be worsening the effects of a devastating fungal disease on the world's amphibians, according to new research published in Nature Climate Change. Researchers found that frogs infected with the disease, known as chytridiomycosis, perished more rapidly when temperatures swung wildly. However scientists told the BBC that more research is needed before any definitive link between climate change and chytridiomycosis mortalities could be made.
3000 new species of amphibians discovered in 25 years
(07/31/2012) The number of amphibians described by scientists now exceeds 7,000, or roughly 3,000 more than were known just 25 years ago, report researchers in Berkeley.
Scientists testing anti-fungal bacteria on diseased frogs in California
(07/23/2012) Researchers are treating tadpoles in Kings Canyon National Park with a bacteria they hope will provide immunity to an infamous fungal disease, reports the San Francisco Gate. The bacteria could be key not only to saving California's mountain yellow-legged frog (Rana muscosa), which is listed as Endangered by the IUCN Red List, but also frog species around the planet, many of which have been decimated by the chytrid fungal disease.
New colorful rainforest frog named after Prince Charles (PICTURES)
(07/04/2012) Researchers have discovered a previously unknown species of frog and named it in honor of Price Charles, according to a paper published in the journal Zootaxa.
96 percent of the world's species remain unevaluated by the Red List
(06/28/2012) Nearly 250 species have been added to the threatened categories—i.e. Vulnerable, Endangered, and Critically Endangered—in this year's update of the International Union for Conservation of Nature's (IUCN) Red List. The 247 additions—including sixty bird species—pushes the number of threatened species globally perilously close to 20,000. However to date the Red List has only assessed 4 percent of the world's known species; for the other 96 percent, scientists simply don't know how they are faring.
Frog secretion illicitly used to help racehorses run faster
(06/21/2012) A compound found in the secretions of a South American frog is being used to boost the performance of racehorses, reports The New York Times.
Extinct toad rediscovered after hiding for 133 years in Sri Lanka
(06/18/2012) A small toad not seen since 1876, and considered by many to be extinct, has been rediscovered in a stream in Sri Lanka. First recorded in 1872, the Kandyan dwarf toad had (Adenomus kandianus) vanished for over a century before being found by scientists during a survey in 2009 in the Peak Wilderness Sanctuary, according to a new paper in Zootaxa.
EPA considers ban on herbicide that triggers sex reversal in frogs
(06/08/2012) The Environmental Protection Agency (EPA) will weigh a ban on Atrazine, a widely used herbicide linked to sex reversal and other reproductive problems in amphibians and fish. The chemical, which is manufactured by Syngenta, has been banned in the European Union since 2004 but some 80 million pounds Atrazine are applied to corn, sugarcane, sorghum and rice in the United States each year.
New frog species leaves scientists' fingers yellow
(05/22/2012) A beautiful, yellow frog species has been discovered in western Panama, according to a new paper in ZooKeys. Scientists were surprised when handling the new species to find their fingers stained bright yellow by its skin, but even after laboratory research the purpose of this dye remains a mystery. The new species, named Diasporus citrinobapheus, is a member of the large rain frog family, whose members skip the tadpole stage and instead are born directly from eggs as tiny froglets.
Frog photos for Save the Frogs Day
(04/28/2012) Today is Save the Frogs Day, a global event that aims to raise awareness on the plight of amphibians, which are increasingly endangered by climate change, habitat loss and degradation, pollution, invasive species, overexploitation, and the outbreak of a deadly fungal disease. In recognition of Save the Frogs Day, there are dozens of activities occurring around the world.
Mad frog bonanza: up to 36 new frogs discovered in tiny Madagascar forest
(04/19/2012) A forest less than half the size of Manhattan sports an astounding number of frogs, according to a new paper in Biodiversity Conservation. Two surveys of Madagascar's Betampona Nature Reserve, which covers 2,228 hectares, has uncovered 76 unique frogs, 36 of which may be new to science. To put this in perspective: the U.S. and Canada combined contain just 88 frog species, but cover an area nearly a million times larger than Betampona.
Two new frogs discovered in Philippines spur calls for more conservation efforts
(04/19/2012) Two new frogs have been discovered on the Philippine island of Leyte during a biological survey last year by Fauna and Flora International, which also recorded a wealth of other species. Discovered in November on the island's Nacolod mountain range, the frogs have yet to be named. The Philippines is one of the world's global biodiversity hotspots, yet suffers from widespread deforestation and degradation.
Photos: the aye-aye of frogs rediscovered after 62 years
(03/27/2012) A pair of researchers have rediscovered a long-lost frog in the tiny African country of Burundi. Known as the Bururi long-fingered frog (Cardioglossa cyaneospila), the species hadn't been seen for over 60 years—since the Soviet Union tested its first nuclear weapon in 1949—but was rediscovered in Bururi Forest Reserve.
Tink frog calls allow researchers to measure population
(03/19/2012) Given their often tiny size and cryptic nature, how does one determine frog populations in the rainforest? Just eavesdrop. A new study in mongabay.com's open access journal Tropical Conservation Society (TCS) employed automated recorders to listen to amphibian calls to determine if the common tink frog (Diasporus diastema) could be found in recovering secondary forests in Costa Rica.
World's most toxic frog gets new reserve
(03/05/2012) Touching a wild golden poison frog could kill you within minutes: in fact, a single golden poison frog, whose Latin name Phyllobates terribilis is even more evocative than its common one, is capable of killing 10 humans with its one milligram dose of poison. Yet the deadly nature of this tiny frog has not stopped it from nearing extinction. Now, in a bid to save the species, the World Land Trust (WLT) and Colombian NGO ProAves have teamed up to establish a 50 hectare (124 acres) reserve in the Chocó rainforest.
Celebrate frogs on leap day!
(02/20/2012) The NGO Amphibian Ark is asking frog-lovers to visit their local zoos on up-coming leap day, February 29th. Dubbed, Leaping Ahead of Extinction, the program includes 58 zoos and other amphibian breeding facilities in seventeen countries that have captive breeding populations of endangered amphibians.
