Deformed frogs have been found in Minnesota and in other parts of the country. They were being studied by the Minnesota Pollution Control Agency and other government agencies to determine the cause of the deformities.
The mission of the North American Reporting Center for Amphibian Malformations, administered by the federal government under the U.S. Geological Survey, is to facilitate the transfer of information on malformed amphibians. By compiling information from both the public and the scientific community, we hope to convey an accurate account of this phenomenon and accelerate its investigation. The Reporting Center is also designed to encourage further collaboration among scientists working to understand the cause(s) of amphibian malformations in the wild. The NARCAM web site has the following sections and subsections: Introduction to the Malformed Amphibian Issue and NARCAM. Where Have Malformations Been Reported? What Do the Malformations Look Like? Know Before You Go: Tips on how to perform a successful survey for malformed amphibians. Technical Information and Aids for Conducting Surveys.
Chytridiomycosis and Ranaviral disease are two amphibian diseases which may cause mass die-offs of amphibians and have the ability to reduce populations to dangerously low levels. The section which follows focuses on Chytridiomycosis, the disease which has been particularly implicated in the global decline of amphibians.

Aim at this site is to provide high quality information on diseases of amphibians with a focus on diseases of significance in wild populations. Much of the information deals with the diseases, particularly chytridiomycosis, associated with amphibian declines.
