(09/09/2009) Frogs are on the edge. Blasted by habitat loss, pollution, and a terrible disease, the chytrid fungus, species are vanishing worldwide and those that remain are clinging to existence, rather than thriving. However, an interview with Pierre Fidenci, President of Endangered Species International (ESI), proves that there are still areas of the world where amphibians remain in abundance. South Korea is not a country that is talked about frequently in conservation circles. Other nations in the region attract far more attention, such as Malaysia and Indonesia. But it was just this neglect that drove Pierre Fidenci to visit the nation and survey the amphibians there.
New species everywhere in Papua New Guinea's 'lost' volcano
(09/07/2009) A five week expedition into a remote extinct volcano has uncovered a treasure trove of new species in Papua New Guinea, including what may be the world's largest rat, a fanged frog, and a grunting fish. In all the expedition estimates it may have found around forty species unknown to science. The expedition was undertaken by a BBC film crew and scientists in January. Local trackers led them into the unexplored jungle, hidden beneath the Bosavi volcano's 2,800 meter summit. Six months prior to arrival, fields of spinach and sweet potato were planted to feed the expedition in such a remote area.
Save the frogs, save ourselves
(09/04/2009) Amphibians are going extinct around the globe. As a scientist specializing in frogs, I have watched dozens of species of these creatures die out. The extinction of frogs and salamanders might seem unimportant, but the reality couldn't be farther from the truth. Indeed, from regulating their local ecosystems, to consuming and controlling the population of mosquitoes and other insects that spread disease, to potentially pointing the way to new drugs for fighting diseases such as cancer or HIV-AIDS, the fate of these creatures is inexorably linked to our own.
Pesticide use linked to dying frogs in California
(08/13/2009) Pesticides used by farmers in California's Central Valley could be killing frogs in the Sierra mountains, report researchers.
Photos: hundreds of new species discovered in Himalayan region, threatened by climate change
(08/10/2009) Scientists from a variety of organizations have found over 350 new species in the Eastern Himalayas, including a flying frog, the world’s smallest deer, and a gecko which has walked the earth for 100-million-years, according to a new report by the World Wildlife Fund (WWF). The report, entitled Where World’s Collide, warns that these rare biological treasures, as well as numerous other species, are threatened in the Eastern Himalayas by climate change.
Photos: treasure trove of new species discovered in Ecuador
(06/16/2009) Near the once-contentious border of Ecuador and Peru in the mountainous forests of the Cordillera del Condor, scientists from Conservation International (CI) conducted a Rapid Assessment Program (RAP), uncovering what they believe are several new species, including four amphibians, one lizard, and seven insects. The team focused on the Upper Nanharitza River Basin, which has been geologically isolated from the rest of the Andes, giving it broad potential for new species.
Approximately 200 new frogs discovered in Madagascar threatened by political instability
(05/11/2009) Amid the amphibian extinction crisis—where amphibians worldwide are disappearing due to habitat loss, pollution, and a devastating fungal epidemic—the Spanish Scientific Research Council (CSIC) has announced some good news. In a survey of the island-nation of Madagascar they have identified between 129 and 221 new species of frogs. The discovery of so many new species nearly doubles the island’s total number of frogs.
The story of ‘Save the Frogs Day’, April 28th, An Interview with Kerry Kriger
(04/26/2009) Founder and director of SAVE THE FROGS!, Dr. Kerry Kriger is responsible for the first annual Save The Frogs Day on Tuesday, April 28th with events planned worldwide from the United States to Nepal, and Australia to China. “I’m continually amazed at the positive response it’s gotten. I thought of Save The Frogs Day one night last December when I was the only full-time SAVE THE FROGS! employee and I only had a couple part-time volunteers,” Kriger explains.
After disease engulfs island, rare mountain chicken frogs airlifted to safety
(04/23/2009) In a rescue operation that sounds straight out of an action film, 50 mountain chicken frogs were airlifted from the Caribbean island Montserrat after the discovery of Chytridomycosis, a fungal disease that has wiped out amphibian populations worldwide. Already, hundreds of the critically-endangered mountain chicken frogs succumbed to the disease, which is thought to have made its way to the island in late 2008 or early 2009.
Amphibians could develop immunity against devastating fungal disease
(04/03/2009) The fungal disease chytridiomycosis has ravaged amphibian populations, including contributing to several extinctions. But new research may bring some hope for currently threatened amphibians.
Have Australian cane toads finally met their match?
(03/31/2009) This weekend in Queensland, Australia the government held the first 'Toad Day Out' where hundreds of locals went hunting for the invasive cane toad, catching an estimated 10,000 toads to be euthanized. At the same time, researchers announced in the journal Functional Ecology that they may have discovered a native Australian species that will finally rout the cane toad—and it's not man. The meat ant is a notoriously aggressive and abundant insect which is known to consume anything edible, including the scientists argue, cane toads.
Photos: Undocumented species discovered in Papua New Guinea
(03/25/2009) Colorful jumping spiders, a tiny frog with a "ringing song" and a striped gecko are among more than 50 previously unknown species discovered during a recent survey in the remote highlands of Papua New Guinea. More than 600 species were documented during the 2008 expedition, which was led by Conservation International (CI) under its Rapid Assessment Program (RAP).
Frogs are an important food source for people in parts of Madagascar
(03/23/2009) With its famous diversity of frog species, Madagascar has long been targeted by smugglers for the pet trade.

Writing in Tropical Conservation Science, researchers from the University of Aberdeen and institutions in Madagascar provide a glimpse into this activity.
Smallest Andean frog discovered in cloud forests of Peru
(03/18/2009) At 3,000 meters (9,842 feet) in the Andes herpetologists were surprised to discover a frog so small it could sit on a dime with room to spare. Further study showed that this new species, named Noble's pygmy frog, is the smallest frog in the Andean mountain range.
Poison frog diversity linked to the Andes
(03/10/2009) Electric colors, wild markings, and toxic skin have made poison frogs well-known inhabitants of the Amazon rainforest. With 353 recognized species, and probably more awaiting discovery, poison frogs are an incredibly diverse group of amphibians. While it has long been believed that the Amazon basin, itself, was the source of their diversity, a new study published in PLoS Biology has uncovered that the Andes mountain chain has served as an oven of evolutionary biodiversity for poison frogs over several million years.

Prioritizing amphibian species for captive breeding to save them from extinction
(11/13/2008) Frogs, toads, salamanders and other amphibians are disappearing at an alarming rate. Of approximately 6,000 amphibian species in the world, about one third are classified as threatened or endangered. A disease caused by a chytrid fungus has devastated frogs living in mid to high elevation streams worldwide. Amphibians also face habitat destruction as forests and wetlands are developed and polluted by agricultural chemicals. In Panama, highland frog populations west of the Canal have declined at an alarming rate.
Scientists can't explain cause of amphibian extinction crisis
(11/13/2008) Scientists have yet to conclusively explain the underlying cause of global declines in amphibian populations, according to a study published in the journal Proceedings of the National Academy of Sciences. The research says that two leading theories for the demise of amphibians — both related to the emergence and spread of the deadly chytrid fungus — are not supported by scientific data.

Good news for amphibians: three new species and one "extinct" frog discovered
(10/01/2008) Amphibians have received a lot of bleak news recently. Last week a report from the Zoological Society of London and EDGE stated that 50 percent of Europe’s amphibians will go extinct by 2050 unless more is done for their conservation. Meanwhile a report published in August found that one in three amphibians worldwide are threatened with extinction, while 200 species have already been lost since the 1980s. Therefore the discovery of three new frog species and the rediscovery of one thought to be extinct provide a little respite from such bad tidings.
More than half of Europe's amphibians face extinction by 2050
(09/28/2008) Researchers with the Zoological Society of London (ZSL) said over half of European amphibians face extinction in less than fifty years due to a perfect storm of threats: climate change, habitat loss, and disease. The announcement came at an event titled ‘Amphibians in a climate of change' hosted by Sir. David Attenborough, one of the world's most well-known wildlife enthusiasts due to his long career making nature documentaries.
Thought-to-be-extinct frog rediscovered in Australia

Amphibians face mass extinction
(08/11/2008) Amphibians are in big trouble. At least one third of the world's 6,300 known species are threatened with extinction, while at least 200 species have gone extinct over the past 20 years. Worryingly the outbreak of a deadly fungal disease, chytridiomycosis, is spreading throughout the tropics leaving millions of victims. A new study, published in the early edition of the Proceedings of the National Academy of Sciences, warns that there is "little time to stave off a potential mass extinction" of frogs, salamanders, and caecilians.
Roads are a major killer of amphibians, reveals study
(05/29/2008) Frogs, toads, and salamanders worldwide are dying from mysterious causes, with possible culprits ranging from habitat loss to fungal diseases. Now, researchers at Purdue University believe they may have identified a significant and surprising contributor to global amphibian declines: traffic. In a recent study, the scientists looked at road kill along several stretches of road in northwestern Indiana and found that 93 percent of the dead animals were amphibians.

No global warming link to dying frogs?
(03/25/2008) Scientists have fired another salvo in the heated debate over the role of climate change in the global decline of amphibians. Writing in the March 25 issue of PLoS Biology, a team of researchers led by Karen Lips of Southern Illinois University-Carbondale report finding "no evidence to support the hypothesis that climate change has been driving outbreaks of amphibian chytridiomycosis" -- a disease blamed for large-scale die-offs of amphibians. Other researchers have argued that climate shifts are worsening the outbreak of the fungal disease.
Rare jewel-colored frog rediscovered in Colombia
(03/13/2008) A brilliantly-colored frog has been rediscovered 14 years after its last sighting in a remote mountainous region in Colombia.
Half of Madagascar's amphibians may still await discovery
(03/11/2008) Madagascar is one of the most unique places on Earth for wildlife. When the public thinks of Madagascar's fauna most likely they think of one of the fifty species of lemur. Yet, Madagascar possesses a wealth of endemic wildlife outside of these unique prosimians. For example, to frog-lovers Madagascar is a paradise. The only amphibians living on Madagascar are frogs; the island is devoid of toads, salamanders, or newts. But what it lacks in other amphibians it makes up for in the number and beauty of its frogs. Currently, 240 frogs have been catalogued in Madagascar, 99 percent of which are endemic. Yet, amphibian expert Dr. Franco Andreone believes that, according to recent field studies, this may only be half of the frogs that actually live in Madagascar. Dr. Andreone believes the final tally could reach 500 species!

The filmmakers achieved their objective and captured the golden frog on film, including rarely seen behvaior.
New research refutes global warming's influence on amphibians' worst enemy
(01/30/2008) There is no doubt that global warming is having a negative effect on amphibians, but it is yet unclear whether or not a direct causal relationship exists between global warming and the spread of a specific fungal epidemic wreaking havoc on amphibian populations worldwide.
Photos: Top 100 most threatened amphibians named
(01/21/2008) Due to numerous factors--including habitat destruction, pollution, climate change, and chytrid fungus--amphibians are probably the most threatened taxon of species in the world. Dr Jonathan Baillie, head of the EDGE organization which has just established an amphibian program, stated that "tragically, amphibians tend to be the overlooked members of the animal kingdom, even though one in every three amphibian species is currently threatened with extinction, a far higher proportion than that of bird or mammal species." To help save these species on the brink, EDGE, apart of the Zoological Society of London, has compiled a list of the hundred most threatened and evolutionary distinct amphibians.
