USDA Forest Service researchers found that site fidelity, the tendency to return to previously occupied habitats, is strong in the Sierra Nevada yellow-legged frog. Research showed how the cumulative effects of a changing climate and introduced non-native trout are negatively impacting the habitat of a species already gone from 90 percent of its historic localities, and will further stress frogs with strong site fidelity. In a 10-year study using mark-recapture methods, Kathleen Matthews and...

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 University of California, Berkeley, biologists. The 75 percent that are chemically castrated are essentially "dead" because of their inability to reproduce in the wild, reports UC Berkeley's Tyrone B. Hayes, professor of integrative biology. "These male frogs are missing testosterone...

Australians have discovered a new weapon in the fight against the dreaded cane toad problem plaguing the country: cat food, reports the Associated Press. According to researchers from the University of Sydney, placing a few tablespoons of cat food next to ponds in the Northern Territory attracts ferocious meat ants. When the baby cane toads come to the surface of the water, the ants turn their attention to them and attack fiercely. The attempt to wipe out the cane toad from Australia has...

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 Jan. 24 in Ecology Letters. The authors of the study, from Imperial College London, the Zoological Society of London and the BiodivERsA project RACE, say their findings suggest conservationists may be able to limit the impact of the disease in the mountains by ensuring tourists...

Scientists in Australia have found that the female cane toad will expand her body if she feels a male 'isn't her type.' According to their study, AFP reports, this suggests frogs and toads may have more power over choosing their mates than we thought. More details on the study appear in the British journal Biology Letters. The mating process is actually quite interesting. The female toad will choose whichever male gives out the best call. Sounds simple enough. However, she must fight off...

Japanese researchers have succeeded in producing goldfish whose beating hearts can be seen through translucent scales and skin, AFP reported. The development is just one part of efforts to reduce the need for school dissections, which have become increasingly controversial, particularly in schools. Yutaka Tamaru, an associate professor in the department of life science at Mie University, said the fish allow them to see a live heart and other organs because the scales and skin have no...

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. After a review of over 28,000 toxicological tests, researchers from the University of South Dakota, Yale University and Washington State University are challenging the prevailing view that amphibians, with their permeable skin and aquatic environment, are particularly sensitive to environmental threats...

MU researchers find clear-cutting is harmful to the terrestrial stage of amphibians Frogs are croaking in clear-cut forests, but not exactly in their traditional manner. University of Missouri researchers found that removing all of the trees from a section of the forest had a negative effect on amphibians during their later life cycles, but had some positive effects during amphibians' aquatic larva stages at the beginning of their lives. To lessen the negative effects during the later life...

Frogs can smell predators when they are still embryos, scientists announced recently. Researchers in the US and Canada discovered that woodfrog embryos could sense any "level of threat" created by salamanders, their enemies. Embryos placed in water full of the odor of salamanders and the smell of hurt tadpoles memorized the predator's scent as a threat. Maud Ferarri, biologist from the University of California, Davis, finds that this kind of learning had been tested in fish, amphibians and...
