"Mammals of the Neotropics" satisfies the need for a comprehensive, up-to-date survey of existing knowledge of South America's terrestrial and marine mammals. No comparable account of South American mammals has ever been published in any language, and this timely work will help encourage the research vital to conservation efforts. This second of a projected three volumes covers southern South America. The authors discuss the historical biogeography and contemporary habitats of the region and then provide individual accounts for nearly 360 indigenous species, including information on size, appearance, ecology, behavior, and life history. Range maps, line drawings, and color plates supplement the text. To place the species accounts in a broader context, the authors consider the diversity of animals within each taxonomic group, examine the Neotropical species from a worldwide geographical perspective, and review taxonomic questions and controversies. Two final chapters deal with the community ecology of mammals and the effects humans have had on the mammalian fauna of the southern cone. Kent H. Redford is coeditor, with John G.
