Amphibian populations fluctuate in size, but around 1989, herpetologists became alarmed by reports that populations and even species were declining — some to extinction. To address this problem, a workshop called “Amphibian population dynamics: Is the threat of extinction increasing for amphibians?” was held in May 1998 in Washington, D.C. The workshop featured investigators with diverse expertise in herpetology, ecology, infectious diseases, ecotoxicology, physiology, climate change, and science policy. The goal of the meeting was to assess the evidence for amphibian population declines, and, if warranted, to recommend a strategy for addressing the causes of the declines. Workshop participants agreed that declines could be traced to four main factors occurring alone, sequentially, or synergistically: habitat destruction, exotic species, disease, and anthropogenic environmental change due to toxic chemicals, ultraviolet radiation, or global climate change.
