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 U.S. Geological Survey (USGS) 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.This re-discovery...

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.Dr Teacher conducted her research with colleagues from the Institute of Zoology and Queen Mary, University of London. The research...

Scientists have discovered evidence of a practically extinct mountain yellow-legged frog in Southern California, where the amphibian has not been spotted in a half-century. Like other amphibians whose populations continue to decline, the frog was thought to have only about 122 adults in the San Gabriel, San Bernardino and San Jacinto mountain ranges. In June, U.S. Geological Survey biologists and a research team from the San Diego Natural History Museum separately discovered a mountain...

When it comes to mating, timing is everything for amphibians. Researchers have found that the mating activity of amphibians is synchronized by the full Moon. The fascinating fact that frogs, toads and newts across the globe seem to enjoy mating by moonlight has never before been noticed. It appears that in order to make sure that a sufficient number of males and females join up at the same time, they use the lunar cycle to co-ordinate their gatherings. This proves to be an ingenious...

California tiger salamanders face a threat from a hybrid relative as well as from over development and pollution, researchers said. Very little development threatened the amphibians 60 years ago when commercial bait sellers in California imported barred tiger salamanders from Texas, a biologist from the University of California Davis told the San Francisco Chronicle. Maureen Ryan of the Center for Population Biology at UC Davis said the larvae of the new salamanders was popular bait, but the...

A team of researchers has discovered that animals that sleep longer store energy for a long duration of time, something scientists believe could be useful the treatment of obesity and other disorders. In an effort to conserve energy when resources are scarce, some species of animals, like the burrowing frog (Cyclorana alboguttata), go through a period of torpor. These frogs can survive for several years buried in the mud without any food or water. They are able to survive such extended...

More than 1,000 Chiricahua leopard frog tadpoles are getting a safe start in life in the Phoenix Zoo. Scientists say that in the wild fewer than 100 of the 1,353 tiny tadpoles would be likely to survive through the summer and become frogs, The Arizona Republic reports. Many would be eaten by fish and others left high and dry in waterless ponds. The zoo is participating in a federal and state conservation plan to increase leopard frog numbers. Researchers expect to have hundreds of frogs to...

Research could have implications for addressing hearing loss in humans 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. Known as Huia cavitympanum, the frog lives only on the Southeast Asian island of Borneo. Ultrasounds are high-pitched sounds more than 20 kilohertz (kHz) in frequency, which exceeds the upper limit of sounds detectable by humans and is far higher...

Scientists in Madagascar have discovered more than 200 new species of frogs, but a political crisis is hurting conservation of the Indian Ocean island's unique wildlife, Reuters reported. Researchers said the recent discovery almost doubles the number of known amphibians in Madagascar and suggests conservationists have over-estimated the natural riches that have helped spawn a $390-million-a-year tourism industry. But newer gains in conservation have been compromised after months of...

A U.S. study suggests amphibians might be able to develop immunity to the fatal fungus disease that is reducing the Earth's amphibian populations. Jonathan Richmond of the U.S. Geological Survey and colleagues said they discovered individual amphibians can develop both acquired and innate immunity to the fungal disease chytridiomycosis, which is caused by the fungus Batrachochytrium dendrobatidis. The researchers said scientists should broaden their studies of chytridiomycosis to include...
