 | The herbicide atrazine, one of the world's most widely used pesticides, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarters of them and turning one in 10 into females, according to a new study by UC Berkeley biologists. These changes occur at atrazine levels below what the EPA considers safe for drinking water. The changes skew sex ratios in the frog population and could be a major cause of amphibian decline worldwide. ...> Full Article |
 | Midwife toads that live in the mountains are highly likely to die from a serious fungal infection, called chytridiomycosis, whereas their infected relatives in the lowlands are not, according to new research published today in Ecology Letters. ...> Full Article |
Reptiles are not known to be the most social of creatures. But when it comes to laying eggs, female reptiles can be remarkably communal, often laying their eggs in the nests of other females. New research in the September issue of the Quarterly Review of Biology suggests that this curiously out-of-character behavior is far more common in reptiles than was previously thought.

Dr. Amber Teacher, studying a post-doctorate at Royal Holloway, University of London, has discovered evidence that a disease may be causing a behavioral change in frogs. The research, published in the August edition of Molecular Ecology, has unearthed a surprising fact about our long-tongued friends: wild frogs in the UK may be changing their mating behavior.

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. Biologists from the US Geological Survey assessing suitability of sites to re-establish frogs and scientists from the San Diego Natural History Museum retracing a 1908 natural history expedition both rediscovered the rare mountain yellow-legged frog in the San Jacinto Wilderness near Idyllwild, Calif.

 | UCLA scientists report on the first frog species that can communicate using purely ultrasonic calls, whose frequencies are too high to be heard by humans. The frog lives only on the Southeast Asian island of Borneo. While most of the more than 5,000 frog species worldwide have eardrums that are flat on the side of their heads, these frogs have eardrums recessed in the side of the skull, similar to mammals. ...> Full Article |

Scientists announce 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.

 | Researchers have discovered that a frog that lives near noisy springs in central China can tune its ears to different sound frequencies, much like the tuner on a radio can shift from one frequency to another. It is the only known example of an animal that can actively select what frequencies it hears. ...> Full Article |
