Amphibians have declined dramatically in the United States and many other areas of the world. These declines seem to have worsened recently and amphibians are now more threatened than many other vertebrate taxa. Agricultural run-off is a possible cause of population decline in amphibians. The effects of agricultural run-off have been identified in many studies, but investigation on the community structure of amphibian populations in running water systems are quite minimal relative to ponds and wetlands.
