As the need increases for sound estimates of impending rates of animal and plant species extinction, scientists must have a firm grounding in the qualitative and quantitative methods required to make the best possible predictions. Extinction Rates offers the most wide-ranging and practical introduction to those methods available. With contributions from an international cast of leading experts, the book combines cutting-edge information on recent and past extinction rates with treatments of underlying ecological and evolutionary causes. Throughout, it highlights apparent differences in extinction rates among taxonomic groups and places, aiming to identify unresolved issues and important questions. Written with advanced undergraduate and graduate students in mind, Extinction Rates will also prove invaluable to researchers in ecology, conservation biology, and the earth and environmental sciences.
