Amphibians Abstract of Seminar Researchers were astonished by the disappearance of amphibians. These factors include acid rain, destruction of natural habitats, reduction in the bone layers. Ultraviolet - B radiation has also been found to damage DNA and cause low levels of photalyase in fertilized amphibian eggs. Declining amphibian populations in many parts of the world are numerous but supporting long-term census data are generally unavailable. Concerns about declines arise because amphibians are an abundant, integral component of many diverse ecosystems.
Amphibians are carnivores that are major consumers of invertebrates, especially insects.
General declines would have widespread consequences and may indicate more general environmental problems. Pechmann, J, D. E. Scott, R.D. Semlitsch, J. P. Caldwell, L. J. Vitt and J. W. Gibbons. August 23, 1991. Research News Vol. Blaustein, A. R. and D. B. Wake.
