Indigenous water frogs under threat
Indigenous water frogs can be crowded out by immigrant or imported species. This is the finding of a Franco-German study. The scientists investigated water frog populations in France and Northern Spain and noticed that the marsh frog (Rana ridibunda), which normally occurs only in Eastern Europe, has the potential to crowd out indigenous species... view more...

Better Smaller, But More
In the city, frogs do not feel as comfortable as in the wild nature because of dirty water, a lack of food, and dangers at every turn. That is why the life of frogs in urban areas is shorter. However, they do not leave these habitats, but adapt to them. Apparently, there are two ways to adapt: either become more tolerant or increase the number of... view more... (2002-04-12)
When threatened, a few African frogs can morph toes into claws
Biologists at Harvard University have determined that some African frogs carry concealed weapons: When threatened, these species puncture their own skin with sharp bones in their toes, using the bones as claws capable of wounding predators. view more (2008-06-24)
Probiotic bacteria protect endangered frogs from lethal skin disease
Laboratory tests and field studies conducted by James Madison University (JMU) researchers continue to show promise that probiotic bacteria can be used to help amphibian populations, including the endangered yellow-legged frog, fend off lethal skin diseases. view more (2008-06-05)
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)
Poison dart frog mimics gain when birds learn to stay away
Studying neotropical poison dart frogs, biologists at the University of Texas at Austin uncovered a new way that the frog species can evolve to look similar, and it hinges on the way predators learn to avoid the toxic, brightly colored amphibians. view more (2006-03-09)
Caribbean frog populations started with single, ancient voyage on South American raft
Nearly all of the 162 land-breeding frog species on Caribbean islands, including the coqui frogs of Puerto Rico, originated from a single frog species that arrived on a sea voyage from South America. view more (2007-06-11)
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)
A missing link settles debate over the origin of frogs and salamanders
The description of an ancient amphibian that millions of years ago swam in quiet pools and caught mayflies on the surrounding land in Texas has set to rest one of the greatest current controversies in vertebrate evolution. The discovery was made by a research team led by scientists at the University of Calgary. view more (2008-05-22)
Scientists Discover 'giant fossil frog from hell'
A team of researchers, led by Stony Brook University paleontologist David Krause, has discovered the remains in Madagascar of what may be the largest frog ever to exist. view more (2008-02-20)
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)
Female concave-eared frogs draw mates with ultrasonic calls
Most female frogs don't call; most lack or have only rudimentary vocal cords. A typical female selects a mate from a chorus of males and then -silently - signals her beau. view more (2008-05-12)
Climate change drives widespread amphibian extinctions
Results of a new study provide the first clear proof that global warming is causing outbreaks of an infectious disease that is wiping out entire frog populations and driving many species to extinction. view more (2006-01-12)
Laos - a lost world for frogs
Frogs and lots of them are being discovered in the Southeast Asia nation of Lao PDR, according to the Bronx Zoo-based Wildlife Conservation Society, which says that six new frog species have been found by scientists over a two-year period. view more (2006-04-24)
New CU-Boulder study shows diversity decreases chances of parasitic disease
A new University of Colorado at Boulder study showing that American toads who pal around with gray tree frogs reduce their chances of parasitic infections known to cause limb malformations has strong implications for the benefits of biodiversity on emerging wildlife diseases. view more (2008-10-22)
Leptin found to control appetite and limb development in frogs
Leptin, the hormone secreted by fat cells that plays an important role in food intake, has been described for the first time in a cold-blooded vertebrate, the South African clawed frog Xenopus. view more (2006-06-13)
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)
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)
Biologists rediscover endangered frog population
For the first time in nearly 50 years, a population of a nearly extinct frog has been rediscovered in the San Bernardino National Forest's San Jacinto Wilderness. view more (2009-07-28)
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)
