Two University of South Florida biologists say the popular weed killer atrazine interferes with the growth of fish and amphibians. Jason Rohr and Krista McCoy, in an article published in Environmental Health Perspectives, reported on their examination of more than 100 studies of the environmental effects of atrazine, The St. Petersburg Times reported. The studies showed that the weed killer does not kill fish or amphibians but can cause changes in their reproductive, immune and other...

The world's leading amphibian experts have come together and for the first time identified two major conservation initiatives to protect the amphibians of the world from becoming extinct. The new coalition of organizations, the Amphibian Survival Alliance, will work together on scientific research and fund-raising to focus on containing the spread of the amphibian chytrid fungus and protecting the only amphibian habitats that contain amphibians that are not found anywhere else in the world....

Male frogs living near urban areas are having trouble competing with the sound of the city, which may be causing the frog population to decline. Male frogs use their croaks to attract their mates. But Melbourne University ecologist Kirsten Parris found that the frogs face a tough task in trying to overpower the loud noise from nearby traffic. "If there are a number of different males calling, the one that sounds the best often gets the girl," Parris told The Associated Press. "You have to be...

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...

The Costa Rican Variable Harlequin Toad, Atelopus varius, known also as the clown frog, is a neo-tropical true toad belonging to the family Bufonidae. Ranging once from Costa Rica to Panama, A. varius is currently listed as critically endangered and has been decreased to a single remnant population near Quepos, Costa Rica and is assumed to be extinct within Panama. Some recent variation in the air temperature, precipitation, stream flow patterns, and the following spread of a pathogenic...

Archey’s frog (Leiopelma archeyi) is one of three or four living species within the Leiopelma genus, which holds frogs that are native to New Zealand. This species can only be found along the Coromandel Peninsula and because it has not changed much throughout the past two hundred million years, it is considered to be a living fossil. Little is known about the habits of Archey’s frog, but it is known to be terrestrial, inhabiting damp areas at high elevations. It is thought that males...

The Maud Island frog is one of the oldest species known. It has been in existence for roughly 200 million years. In 2006, 60 Maud Island frogs were introduced to a predator free sanctuary. Thirty others were also released outside the sanctuary for comparison. In February 2008, 13 juvenile frogs...
