Herbicide Spurs Reproductive Problems In Many Animals
2011-11-29 04:19:57

An international team of researchers has reviewed the evidence linking exposure to atrazine — an herbicide widely used in the U.S. and more than 60 other nations — to reproductive problems in animals. The team found consistent patterns of reproductive dysfunction in amphibians, fish, reptiles and mammals exposed to the chemical. Atrazine is the second-most widely used herbicide in the U.S. More than 75 million pounds of it are applied to corn and other crops, and it is the most...

Predators Drive Evolution Of Poison Dart Frogs' Skin Patterns
2011-11-22 04:10:01

Natural selection has played a role in the development of the many skins patterns of the tiny Ranitomeya imitator poison dart frog, according to a study that will be published in an upcoming edition of American Naturalist by University of Montreal biologist Mathieu Chouteau. The researcher's methodology was rather unusual: on three occasions over three days, at two different sites, Chouteau investigated the number of attacks that had been made on fake frogs, by counting how many times that...

Springy Tendons Key To Frogs' Amazing Leaps
2011-11-17 04:08:54

The secret to frogs´ superlative jumping lies in their tendons. Researchers at Brown University, filming frogs jumping at 500 frames per second with special X-ray technology, show that the frog's tendon stretches as it readies its leap and then recoils, much like a spring, when the frog jumps. The finding could explain how other animals are exceptional leapers. Results appear in Biology Letters. Some species of frogs and many other animals are able to jump far beyond what appear to be...

Tree Frogs Chill Out To Collect Water
2011-09-30 04:08:40

Research published in the October issue of The American Naturalist shows that Australian green tree frogs survive the dry season with the help of the same phenomenon that fogs up eyeglasses in the winter. According to researchers from Charles Darwin University in Australia, tree frogs often plop themselves down outside on cool nights during the dry season in tropical Australia. When they return to their dens, condensation forms on their cold skin–just like it does on a pair of...

A PLoS ONE press release Usually it's the frog that catches the unsuspecting bug for a tasty snack, but in an unprecedented predator-prey role reversal, a certain group of ground beetle larvae are able to lure their amphibious would-be predators and consume them with almost 100% success. In a report published today in the online journal PLoS ONE, researchers begin to describe how these larvae are able to pull off this feat. According to the researchers, larvae of the genus Epomis...

SF State's Vance Vredenburg and team continue focus on mass extinction of amphibians An international team of researchers has completed the first major survey in Asia of a deadly fungus that has wiped out more than 200 species of amphibians worldwide. The massive survey could help scientists zero in on why the fungus has been unusually devastating in many parts of the globe -- and why Asian amphibians have so far been spared the same dramatic declines. The disease chytridiomycosis, caused by...

Female cognitive ability can limit how melodious or handsome males become over evolutionary time, biologists from The University of Texas at Austin, Louisiana State University Health Sciences Center and the Smithsonian Tropical Research Institute have observed. Males across the animal world have evolved elaborate traits to attract females, from huge peacock tails to complex bird songs and frog calls. But what keeps them from getting more colorful feathers, longer tails, or more melodious...

A research team that included Hamilton E. Farris, PhD, Research Assistant Professor of Neuroscience and Otorhinolaryngology at LSU Health Sciences Center New Orleans, reveals that two entirely different species show similar perception of auditory cues that drive basic biological functions; that these perceptions may be universally shared among animals; and that such perception may also limit the evolution of communication signals. The work is published in the August 5, 2011 issue of Science....
