In this volume thirty-six scientists from Latin American and the United States contribute substantially to our knowledge of Latin American mammals. Part 1 provides a history of the pioneers in collection-based mammalogy, which began only about two centuries ago. Chapters in Part 2 demonstrate the search for theories and methodologies that will help us understand how the fauna of this region came to be. Part 3 addresses conservation policy and management in light of recent enormous changes in the natural habitats of Latin America. Part 4 explores the need for conservation-education programs in Latin America as a critical step in the development of a sound land-use ethic. The preface of Latin American Mammalogy, overviews of the four sections, and summaries of the twenty-three chapters are given in Spanish as well as English.
