"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."
