Amphibian Declines

In recent years in North America and in other locales, there has been a surge of interest in the status and conservation of amphibian populations. Concern centers on the disappearance or decline of individual populations, species, and even geographic assemblages of amphibians, particularly anurans. Although there is likely no one cause for population declines in many scattered regions or for the deformities reported in midwestern North America, researchers are now feverishly developing monitoring and research programs that can only aid in our understanding of amphibian population dynamics and the importance of amphibians to ecosystem function. Head-starting, relocation, repatriation, and translocation (HS/RRT), often in conjunction with captive breeding, have frequently been suggested as viable options in the conservation of amphibians. This chapter reviews recent projects employing HS/RRT solutions to problems facing imperiled amphibians.
