Scientists say the four-day testing period the U.S. Environmental Protection Agency uses to determine safe levels of pesticide exposure is too short. The University of Pittsburgh researchers said they found the highly toxic pesticide endosulfan -- a neurotoxin banned in several nations, but still used extensively in U.S. agriculture -- can exhibit a lag effect with the fallout from exposure not occurring until after direct contact has ended. The team that included lead author Devin Jones,...

The four-day testing period the U.S. Environmental Protection Agency (EPA) commonly uses to determine safe levels of pesticide exposure for humans and animals could fail to account for the toxins' long-term effects, University of Pittsburgh researchers report in the September edition of Environmental Toxicology and Chemistry.The team found that the highly toxic pesticide endosulfan"”a neurotoxin banned in several nations but still used extensively in U.S. agriculture"”can exhibit...

Researchers in China have discovered the first protein-based toxin in an amphibian "“a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison.While gene-encoded protein toxins have been identified in many vertebrate animals, including fish, reptiles and mammals, none have yet been found in amphibians or birds. In the case of poisonous amphibians, like the tropical poison...

More than 350 new species including the world's smallest deer, a flying frog, a 100 million-year old gecko, and the first new monkey to have been discovered in over a century have been found in the last ten years located in the Eastern Himalayas. Now, climate change threatens this biologically rich habitat. An environmental group says the growing pressures from unsustainable development in the area is confronting the vital habitats of the mountain range spanning across Nepal, China, India,...

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...
