Amphibian declines: review of some current hypotheses

Abstract/Summary

The documented and hypothesized causes of declines in amphibian populations fall into three categories: habitat destruction and alteration. global anthropogenic influences, and natural causes. I will not review all of these in detail because some are the subjects of other chapters in this volume. I will discuss effects of introduced predators and increasing ultraviolet radiation more thoroughly because these factors represent extremes in our ability to explain and possibly reverse declines.
