Smithsonian scientists find the frog legs trade may facilitate spread of pathogens
Most countries throughout the world participate in the $40-million-per-year culinary trade of frog legs in some way, with 75 percent of frog legs consumed in France, Belgium and the United States. view more (2009-11-20)
Amphibians as environmental omen disputed
Amphibians, for years considered a leading indicator of environmental degradation, are not uniquely susceptible to pollution, according to a meta-analysis to be published in Ecology Letters. view more (2009-11-12)
Do 3 meals a day keep fungi away?
The fact that they eat a lot - and often - may explain why most people and other mammals are protected from the majority of fungal pathogens, according to research from Albert Einstein College of Medicine of Yeshiva University. view more (2009-10-16)
Transgenic songbirds provide new tool to understand the brain
You can learn a lot from an animal. By manipulating the DNA of mice, flies, frogs and worms, scientists have discovered a great deal about the genes and molecules behind many of life's essential processes. view more (2009-09-29)
Secrets of the 4 chambers revealed by reptile hearts
The first genetic link in the evolution of the heart from three-chambered to four-chambered has been found, illuminating part of the puzzle of how birds and mammals became warm-blooded. view more (2009-09-03)
The first gene-encoded amphibian toxin isolated
Researchers in China have discovered the first protein-based toxin in an amphibian -a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison. view more (2009-08-18)
Pitt research suggests EPA pesticide exposure test too short, overlooks long term effects
The four-day testing period the U.S. Environmental Protection Agency (EPA) commonly uses to determine safe levels of pesticide exposure for humans and animals could fail to account for the toxins' long-term effects, University of Pittsburgh researchers report in the September edition of Environmental Toxicology and Chemistry. view more (2009-08-18)

Mayo Clinic researchers find first potential pathogenic mutation for restless legs syndrome
An international team of researchers led by scientists at the Mayo Clinic campus in Florida have found what they believe is the first mutated gene linked to restless legs syndrome, a common neurologic disorder. view more (2009-07-22)
UCLA scientists discover ultrasonic communication among frogs
UCLA scientists report for the first time on the only known frog species that can communicate using purely ultrasonic calls, whose frequencies are too high to be heard by humans. view more (2009-05-11)
The life histories of the earliest land animals
The fossil record usually shows what adult animals looked like. But the appearance and lifestyle of juvenile animals often differ dramatically from those of the adults. view more (2009-04-21)
Researchers identify gene associated with muscular dystrophy-related vision problems
Skeletal muscle disease and vision deficits might seem unrelated, but a frog model of muscular dystrophy shows it is not such a leap. view more (2009-04-21)
Conserved gene expression reveals our 'inner fish'
A study of gene expression in chickens, frogs, pufferfish, mice and people has revealed surprising similarities in several key tissues. view more (2009-04-16)
Amphibians may develop immunity to fatal fungus
Amphibian populations are declining worldwide, principally because of the spread of the fungal disease chytridiomycosis. Researchers know that some amphibian populations and species are innately more susceptible to the disease than others. view more (2009-04-01)
New species of spiders discovered by UBC scientist in Papua New Guinea
A University of British Columbia researcher has discovered dozens of species of jumping spiders that are new to science, giving scientists a peek into a section of the evolutionary tree previously thought to be sparse. view more (2009-03-25)
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)
10 new amphibian species discovered in Colombia
Scientists today announced the discovery of 10 amphibians believed to be new to science, including a spiky-skinned, orange-legged rain frog, three poison dart frogs and three glass frogs, so called because their transparent skin can reveal internal organs. view more (2009-02-03)
Climate change effects on imperiled Sierra frog examined
Climate change can have significant impacts on high-elevation lakes and imperiled Sierra Nevada Yellow-legged frogs that depend upon them, according to U.S. Forest Service and University of California, Berkeley, scientists. view more (2008-12-11)
Global warming link to amphibian declines in doubt
Evidence that global warming is causing the worldwide declines of amphibians may not be as conclusive as previously thought, according to biologists. The findings, which contradict two widely held views, could help reveal what is killing the frogs and toads and aid in their conservation. view more (2008-11-13)
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)
