UGA study reveals ecosystem-level consequences of frog extinctions
Streams that once sang with the croaks, chirps and ribbits of dozens of frog species have gone silent. They're victims of a fungus that's decimating amphibian populations worldwide. view more (2008-10-17)
Pitt Research Finds That Low Concentrations of Pesticides Can Become Toxic Mixture
Ten of the world's most popular pesticides can decimate amphibian populations when mixed together even if the concentration of the individual chemicals are within limits considered safe. view more (2008-11-12)
Captive breeding introduced infectious disease to Mallorcan amphibians
A potentially deadly fungus that can kill frogs and toads was inadvertently introduced into Mallorca by a captive breeding programme that was reintroducing a rare species of toad into the wild, according to a new study published today in the journal Current Biology. view more (2008-09-22)
Stanford researchers: Global warming is killing frogs and salamanders in Yellowstone Park
Frogs and salamanders, those amphibious bellwethers of environmental danger, are being killed in Yellowstone National Park. The predator, Stanford researchers say, is global warming. view more (2008-10-29)
Amphibians in losing race with environmental change
Even though they had the ability to evolve and survive for hundreds of millions of years - since before the time of the dinosaurs and through many climatic regimes - the massive, worldwide decline of amphibians can best be understood by their inability to keep pace with the current rate of global change, a new study suggests. view more (2007-05-01)
Harlequin frog rediscovered in remote region of Colombia
After 14 years without having been seen, several young scientists supported by the Conservation Leadership Programme (CLP), have rediscovered the Carrikeri Harlequin Frog (Atelopus carrikeri) in a remote mountainous region in Colombia. view more (2008-03-12)
Beavers helping frogs, toads survive
The humble beaver, besides claiming a spot of honour on the Canadian nickel, is also helping fellow species survive. view more (2007-01-12)
Study shows frogs can play key role in stem cell research
It sounds like one of those curiosities which pops up in wildlife documentaries, but the African clawed frog could prove a powerful ally for scientists working in the key area of stem cell research. view more (2006-05-15)
Nutrients cause increase in parasites and frog deformities
Extra and missing-legged frogs have become increasingly common in North American wetlands over the last decade. Research implicates a flatworm parasite, Ribeiroia ondatrae, as the culprit of these deformities. Reasons for the apparent increase in infection and malformations, however, have remained a mystery. In the July issue of Ecology Letters,... view more... (2004-06-10)
Opening a channel for salt retention
A research team has developed the first small molecule that can reversibly activate a key protein involved in balancing sodium levels, paving the way for drugs that can treat low blood pressure and related conditions. view more (2008-04-28)
Scientists document salamander decline in Central America
The decline of amphibian populations worldwide has been documented primarily in frogs, but salamander populations also appear to have plummeted, according to a new study by University of California, Berkeley, biologists. view more (2009-02-10)
New golden frog discovered in remote region of Colombia
A new poisonous frog was recently discovered in a remote mountainous region in Colombia by a team of young scientists supported by the Conservation Leadership Programme (CLP). view more (2007-08-29)
Underestimation of frog numbers causes concern
Frogs are vanishing from all the world's ecosystems with unprecedented speed. It is thought that more than 100 species have died out since 1980 alone. view more (2007-10-31)
Spring fishing season arrives... and with it, amphibian diseases
Waterdogs, they're called, these larvae of tiger salamanders used as live bait for freshwater fishing. view more (2009-04-08)
Wildlife researchers identify impacts of contamination in amphibians
Bill Hopkins, fisheries and wildlife associate professor in Virginia Tech's College of Natural Resources, and colleagues doing research at the Savannah River Ecology Laboratory and in the field, have demonstrated that amphibians are exposed to contaminants through maternal transfer, as has been proven for other vertebrates. view more (2006-02-22)
My, what big teeth you had! Extinct species had large teeth on roof of mouth
When the world's land was congealed in one supercontinent 240 million years ago, Antarctica wasn't the forbiddingly icy place it is now. But paleontologists have found a previously unknown amphibious predator species that probably still made it less than hospitable. view more (2008-09-12)
Priority regions for threatened frog and toad conservation in Latin America
Nearly 35% of all amphibians are now threatened of extinction raising them to the position of the most endangered group of animals in the world. view more (2008-05-07)
Road losses add up, taxing amphibians and other animals
When frogs hit the road, many croak. Researchers found more than 65 animal species killed along a short stretch of roads in a Midwestern county. Nearly 95 percent of the total dead were frogs and other amphibians, suggesting that road-related death, or road-kill, possibly contributes to their worldwide decline, a trend that has concerned and... view more...

Early exposure to common weed killer impairs amphibian development
Tadpoles develop deformed hearts and impaired kidneys and digestive systems when exposed to the widely used herbicide atrazine in their early stages of life, according to research by Tufts University biologists. view more (2008-04-16)
Race to halt global amphibian crisis boosted by rediscovery of endangered Colombian frogs
The rediscovery of two frog species feared extinct has made a new Colombian protected area the focal point for efforts to save amphibians from a deadly fungus decimating their populations in Central and South America. view more (2006-06-07)
