A major shift is underway in the field of biology, as many biologists see that the systems with which they work are rapidly disappearing. The new book, Conservation Biology: The Theory and Practice of Nature Conservation, Preservation and Management represents the state-of-the-art in the field. The editors have brought together a number of leading authorities in the fields of biological diversity and conservation where contributions cover both species and habitats. The integrated chapters of this book cover the patterns and processes of diversity, rarity and extinction; the fragmentation of habitats; deforestation and conservation; the monitoring, assessment, and management of biological diversity; and the practice of conservation biology. This book should be of interest to students of biology, as well as ecologists and evolutionary biologists.
