"Shuster and Wade place the study of animal mating systems and alternative mating strategies in a comprehensive theoretical framework. This framework is both elegantly simple and comprehensive. Most importantly they demonstrate with real life examples the utility of their approach and demonstrate that it can be tested empirically. It will serve as a benchmark for research in this area for many years to come."--Derek Roff, University of California, Riverside

"This ambitious and wide-ranging book offers new ways to look at sexual selection and its many consequences. Shuster and Wade have done the field a great service by challenging existing theory with respect to the evolution of mating systems and alternative mating strategies. Because they also provide the key predictions derived from their approach, they and others will be able to test their ideas even more fully in the years ahead. Let the fun begin. "--John Alcock, Arizona State University

"This important and original book addresses the issues that are attracting attention from a broad community studying the evolution of reproductive strategies. Its comprehensiveness and rigor give it the potential to influence a large field of research, and its personal perspective gives it the potential to redirect the field. The authors boldly challenge many current views of mating systems and alternative mating strategies. If they are correct, this book will likely become a landmark."--Mart Gross, University of Toronto

"This is an exceptional and thought provoking contribution to behavioral ecology. It uses excellent examples, slays some sacred cows, and is superbly written and often brilliant."--Barry Sinervo, University of California, Santa Cruz
