Patterns of distribution of amphibians

the long version

"At a time when populations of many species of amphibians are declining from unknown causes, indicating the destruction of natural habitats, biologists and conservationists need to know the patterns of distribution of amphibians and where large numbers of species and endemics occur.". "Patterns of Distribution of Amphibians: A Global Perspective, edited by William E. Duellman, is the first synthesis of information on the world-wide distribution of amphibians. Chapters on each of nine global regions are written by internationally recognized experts, who have gathered the diverse data from the literature and from their own experience in the field. The regional treatments emphasize patterns of distribution and their interpretation with respect to geography, climate, vegetation, and evolutionary history providing unique syntheses of these patterns. The contributors also address existing and recommended aspects of conservation."--BOOK JACKET.
