'The Guenons is encyclopedic in its coverage of this remarkably diverse group of primates. From chapters on evolutionary history, behavior, ecology, and conservation, The Guenons also offers a window into the world of primatology, as seen through the lenses of these monkeys and the researchers who study them. Glenn and Cords should be commended for assembling such an impressive set of contributions from so many guenon experts. This volume will be the standard reference on the guenons for many years to come.' Karen B. Strier, University of Wisconsin-Madison 'This book is a cornucopia of recently-gathered knowledge about the natural history of Africas most species-rich group of anthropoids. The volume is particularly strong on behavioral ecology, but it also presents important new evolutionary analyses and, in a useful section on conservation, makes practical suggestions to address the growing threats posed to the survival of African primates by ever-increasing habitat loss and hunting.' John F. Oates, Hunter College 'Guenons are one of the most specifically diverse groups of living primates, but the true extent of their behavioral, ecological, and phylogenetic diversity has remained largely unappreciated. This exciting volume describes many new aspects of guenon biology. The authors use the diversity of guenons to address, and often question, several major tenets of primate socioecology. Most significantly, this volume thoroughly demolishes the view that guenons are a uniform radiation.' John G. Fleagle, State University of New York at Stony Brook 'A comprehensive and valuable collection and an essential reference for any primatologists. Highly recommended.' L.
