In the last three years, two new causes, perhaps related, have been suggested. Animals with damaged immune systems may fall prey to bacteria and viruses that they might otherwise withstand. And most recently Robert Stebbins, emeritus professor of zoology at University of California at Berkeley, has suggested that amphibian population declines may be caused by environmental pollutants that mimic estrogens and disrupt the endocrine and immune systems of amphibians. During the change from tadpole to frog, the creature stops eating, stressing its whole system. Of course no one knows what's really going on in nature.
