USGS seeks citzens of all ages to listen for frogs and toads
Hundreds of U.S. citizens from 47 states are helping to count frogs and toads as part of Frogwatch USA, a USGS educational and science program that provides people with an opportunity to learn about the environment while collecting valuable information about their local frogs and toads. And with the melodious calls of Pacific treefrogs and Arroyo toads in California now beginning to fill the night air, the second year of this program has officially begun. (2000-02-27)

Amphibian declines complicated, disturbing
People who are looking for a magic bullet that will explain all of the amphibian deaths and declines around the world are going to be disappointed. It's now a certainty that there are multiple causes. But the lack of a single, definite cause does not diminish the seriousness of this alarming ecological phenomenon. (2000-02-17)

Link between climate change, amphibian declines explored
Although a NASA-funded study to search for links between local climatic variation and the beginning of amphibian declines in three specific areas of the world has found no significant correlation, a disease that has caused numerous amphibian deaths recently may be indirectly influenced by climate and environmental factors, according to a University of Colorado professor. (2000-02-17)

ASU scientists probe salamander mysteries
ASU biologists think they have found a major cause of the amphibian die-offs in the Rocky Mountains of North America, having isolated an iridovirus in dying salamanders from remote desert ponds. However, where the virus came from and how it spreads are more troubling questions, with implications for the worldwide amphibian decline. (2000-02-17)

Complex mystery of amphibian decline calls for a new kind of science
Central American forests that used to throb with the songs of frogs have fallen eerily silent. Similar change is happening in North America and Australia. A multidisciplinary team of 24 scientists headed by ASU biologist James Collins thinks the reason why may be found by combining epidemiology and ecology. (2000-02-13)

Fertilizers linked to amphibian deaths
Researchers have discovered that a level of nitrogen-based compounds which the EPA says is safe for human drinking water - a level often found in agricultural areas as a result of using crop fertilizers - is enough to kill some species of amphibians. (2000-01-04)

Mass extinction of freshwater species in North America
The first estimate of extinction rates of North America's freshwater animals shows that they are the most endangered group on the continent. (1999-09-29)

USGS issues wildlife health alert: Chytrid fungus infection
Recent deaths of endangered boreal toads in one of the largest remaining populations in the southern Rocky Mountains have been linked to a chytrid fungus identified last year as being responsible for amphibian die-offs in Central America and Australia, according to pathologists at the USGS National Wildlife Health Center in Madison, Wis. (1999-09-10)

Trouble for the world's turtles
About half of the world's turtle species face possible extinction -- due in large part to a growing demand for turtles as a popular dining delicacy and a source of traditional medicines. Sixty of the world's leading experts on freshwater turtles reached that conclusion at a special gathering in Nevada this month. (1999-08-25)

Mosquito fish may be wiping out amphibians
Mosquito fish introduced for biological control to eat mosquito larvae actually prefer eating amphibians, according to a study in California. The fish could be causing the decline in populations of amphibians such as the Californian treefrog. (1999-08-25)

Mosquitofish threaten amphibians
Sometimes you have to prove the obvious to get something done. The mosquitofish is being distributed around the world to control mosquitoes--without regard for its effects on other aquatic species. New research shows that mosquitofish devour tadpoles just as readily as mosquito larvae and so can decimate native amphibians. (1999-07-29)

Salamanders may one day monitor degradation in small streams
Lungless salamanders may join fish and stream bugs as indicators of the environmental health of small streams, according to Penn State researchers. (1999-06-25)

Parasites, Not Pollution, Responsible For Some Frog Deformities, As Reported In The 30 April Issue Of Science
Parasite infections are the likely cause behind the bizarre deformities that endow frogs with up to 12 hind legs, according to two studies in Science. (1999-04-30)

Amphibian Revival: Build It And They Will Come
The Budweiser beer frogs may be gone, but wood frogs in eastern Missouri have come back with gusto. Wood frogs that had been extinct in eastern Missouri and spotted salamanders that had been greatly reduced have returned through a long- term conservation effort by biologists at Washington University in St. Louis. (1999-02-24)

Alien Species Cost U.S. $123 Billion A Year
A few of the more than 30,000 non-indigenous species in the United States cost $123 billion a year in economic losses, Cornell University ecologists estimate. Ecologist David Pimentel includes alien weeds (cost: $35.5 billion), introduced insects ($20 billion), human disease-causing organisms ($6.5 billion) and even the mongoose ($50 million ). (1999-01-24)

USGS Issues Wildlife Health Alert: Associates Virus With Salamander Die-Offs
A recent die-off of salamanders in Utah has prompted USGS wildlife health officials to issue an October 21, 1998 wildlife health alert. The incident followed salamander die- offs earlier this summer in Maine and North Dakota. In all three cases a virus is believed to be responsible. (1998-10-22)

Wistar Scientists Locate Genes Involved In Mammalian Tissue Regeneration
Five years ago, Wistar scientist, Ellen Heber-Katz, Ph.D., identified a (1998-09-30)

Advances In Analyzing Environmental Endocrine Disruptors And Their Effects On Health, Environment
Scientists from government agencies, academe and industry will present the latest research on environmental endocrine disruptors and their impact on human health and the environment. Two dozen research reports will be presented during this special two-day symposium at the national meeting of the American Chemical Society, the world's largest scientific society. (1998-08-26)

Fatal Frog Fungus Found In The United States
The fungus that made headlines as an amphibian killer in Australia and Central America has turned up in a dying wild frog in Arizona, according to the July 4 Science News. The discovery raises the possibility that chytrid fungi have played a role in mysterious amphibian declines in the United States. (1998-07-02)

USGS Responds to Amphibian Declines With Program In Great Smokey Mountains National Park
Frogs, toads, and salamanders are just a few of the 40 species of amphibians that U.S. Geological Survey scientists will survey over the next 5 years in the Great Smoky Mountains National Park, a region that has the greatest diversity of amphibians in North America. (1998-05-29)

Increasing Threat Of Extinction For Amphibians? Scientists To Seek Answers At NSF Workshop

Two Environmental Articles: Deformed Frogs & Dioxin In Old Soil

Amphibian Mortality Due To UV Radiation
Yale University -- Field experiments in the Oregon Cascade Mountains have confirmed what many scientists had suspected - - ambient levels of ultraviolet-B (UV-B) radiation from the sun can cause high rates of mortality and deformity in some species of frogs and other amphibians. The earth is shielded from UV radiation by the ozone layer, which is believed to be thinning because of the increased use of chlorofluorocarbons as refrigerants, solvents and cleaning agents.
