Scientists track amphibian populations because these animals are sensitive to changes in their environment and can serve as "canaries in the coal mine" to give researchers early warnings about pollution or other ecological problems. But new research from North Carolina State University shows that data from the largest amphibian monitoring program in the country may have flaws that, if uncorrected, could result in overestimates of frog populations. The U.S. Geological Survey launched the North...

Sometimes divers, to their own painful dismay, do belly flops. But did you ever see a frog belly flop? That's just what primitive living frogs do, according to a new study by Dr. Richard Essner, from Southern Illinois University Edwardsville in the US, and colleagues, looking at the evolution of frog jumping and landing. They found that frogs became proficient at jumping before they perfected landing. This evolutionary split, characterized by an inability to rapidly rotate the limbs forward...

Incidence of a lethal infectious disease moves at a rate of 30 kilometers per year A killer has been caught in the act: the first before-and-after view of an infectious disease that led to an amphibian die-off has been released by the scientists who tracked it. The results are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). Like a wave, incidence of the fungal disease that wipes out Central American frogs--chytridiomycosis--advances through the...

Dr Andrew Johnson is speaking today (July 12) at the UK National Stem Cell Network annual conference. He and his team from the University of Nottingham have been using a Mexican aquatic salamander called an axolotl to study the evolution and genetics of stem cells - research that supports the development of regenerative medicine to treat the consequences of disease and injury using stem cell therapies. This team has found that there are extraordinary similarities in the development of...

As global warming threatens many animal species with extinction, the already destructive cane toad is set to flourish with increasing temperature, say Australian scientists "The negative effect of high temperature does not operate in Cane Toads, meaning that toads will do very well with human induced global warming", explains Professor Frank Seebacher from the University of Sydney. Unlike fish and other cold-blooded creatures, whose oxygen transport system suffers at high temperatures, the...

Trying to stay ahead of a deadly disease that has wiped out more than 100 species, scientists at the Smithsonian Tropical Research Institute continue to discover new frog species in Panama: Pristimantis educatoris, from Omar Torrijos National Park, and P. adnus from Darien Province near the Colombian border. In 1989 researchers realized that frogs were dying around the world. Then they identified the cause: a fungal disease called chytridiomycosis. In 2004 Karen Lips, associate professor at...

Using experiments involving a mechanical shaker and a robotic frog, researchers reporting online on May 20th in Current Biology, a Cell Press publication, have found new evidence that male red-eyed treefrogs communicate with one another in aggressive contests by using vibrations they send through their plant perches. The findings open the door to further study of what has been a neglected channel for vertebrate communication. "In the case of red-eyed treefrogs, tremulation displays in which...

The world's most ancient frogs may soon be mined to extinction, if the New Zealand government's plans to open up a conservation area for mining go ahead. The primitive Archey's frog (Leiopelma archeyi) and Hochstetter's frog (Leiopelma hochstetteri) are two of the species that inhabit the area of 'high conservation value' on New Zealand's North Island where the mining is planned to take place. Archey's frog is currently ranked top of the Zoological Society of London's (ZSL) EDGE of Existence...

Scientists have unraveled the dynamics of a deadly disease that is wiping out amphibian populations across the globe. New findings, published May 10 in the Proceedings of the National Academy of Sciences, suggest that infection intensity -- the severity of the disease among individuals -- determines whether frog populations will survive or succumb to an amphibian fungal disease called Chytridiomycosis. The research identifies a dangerous tipping point in infection intensity, beyond which...

A team of scientists led by the Department of Energy's Joint Genome Institute (JGI) and the University of California, Berkeley, is publishing this week the first genome sequence of an amphibian, the African clawed frog Xenopus tropicalis, filling in a major gap among the vertebrates sequenced to date. "A lot of furry animals have been sequenced, but far fewer other vertebrates," said co-author Richard Harland, UC Berkeley professor of molecular and cell biology. "Having a complete catalog of...

The Foothill Yellow-Legged Frog (Rana boylii) is a small frog measuring about 1.46 to 3.2 inches. It belongs to the genus Rana within the Ranidae family. This species can be found from northern Oregon, down California’s west coast, and into Baja California, Mexico. Both the Columbia Spotted Frog and the Cascades Frog, also part of the Rana genus, reside in the northern regions of this frog’s territory. They show a preference for living in streams and rivers, and lay their eggs in masses...

It is small and it can be found in wet tree hollows or leaf bases that contain water. This slender frog features a moderately sized head with a pointed snout and vertical lores. The distance between the eyes is as wide as the width of the upper eyelid. The opening of the ear is well marked and is about a third of the diameter of the eye. The fingers are...

Its natural habitats are subtropical or tropical, moist, lowland forests and rivers. It’s threatened by habitat loss. Like all members of the genus Phyllobates, Golfodulcean Poison Frogs have highly potent neurotoxin alkaloid poisons in their skin. While it’s only the fourth most toxic of the genus, the Golfodulcean Poison Frog is still a highly...
