The effects of acid precipitation on amphibians.

: A large number of studies conclusively demonstrate that low pH conditions have important ecological effects on amphibian communities. These effects vary developmentally and depend on complex interactions with other physical, chemical, and biological parameters. Acid sensitivity varies widely within and among species of amphibians. In spite of the importance of acidity to their reproductive success and the presence of many acidic amphibian habitats, there is, at present, little direct evidence that acid precipitation has produced widespread declines in amphibian populations. However, the potential role of sublethal effects of acidity on amphibian declines has not been studied thoroughly.
