Who are the major organizations working on experiments and what kind of conclusions do they hold based on the results of the experiments?
The major organizations are the Pollution Control Agency (PCA), the Environmental Protection Agency (EPA), the National Institute of Environmental Health Services (NIEHS), and some universities. There are many theories about what is causing the deformities/declines in amphibian populations. For example, the PCA and NIEHS believe it is something in the water; the EPA believe that UV-B is the main culprit; and some researchers at a university in California believe that retinoic acid, a componenet of Methoprene (a mosquito spray), is the main cause of malformities.
