Tóm tắt

The first global assessment of amphibians provides new context for the well-publicized phenomenon of amphibian declines. Amphibians are more threatened and are declining more rapidly than either birds or mammals. Although many declines are due to habitat loss and overutilization, other, unidentified processes threaten 48% of rapidly declining species and are driving species most quickly to extinction. Declines are nonrandom in terms of species' ecological preferences, geographic ranges, and taxonomic associations and are most prevalent among Neotropical montane, stream-associated species. The lack of conservation remedies for these poorly understood declines means that hundreds of amphibian species now face extinction.

We are grateful to the more than 500 herpetologists who generously gave of their time and knowledge to compile the GAA data. R. Akçakaya T. Brooks D. Church M. Denil D. Frost C. Gascon G. da Fonseca M. Foster C. Hilton-Taylor M. Hoffmann T. Lacher P. Langhammer G. Mace L. Manler L. Master A. Mitchell R. Mittermeier D. Wake and F. Xie provided extensive help and advice on the implementation of the GAA. The majority of the distribution maps used for U.S. species were adapted from the United States Amphibian Atlas Database which was assembled at Ball State University by P. Nanjappa L. Blackburn and M. Lannoo and which was supported in part by grants and/or matching funds from the National Fish and Wildlife Foundation United States Fish and Wildlife Service and Disney Wildlife Conservation Fund.
