Since the last major work on long-tailed monkeys was produced, additional guenon species and subspecies have been discovered, previously unstudied guenon species have become the subject of long-term research projects, and knowledge of the more well-known guenon species has greatly increased. This volume presents information and insight on research previously studied and newly discovered. A wide range of topics related to guenon biology is presented, including evolution, taxonomy, biogeography, reproductive physiology, social and positional behaviour, ecology, and conservation. Composed of 26 chapters compiled by 47 authors, many of whom are young investigators in their field, "The Guenons: Diversity and Adaptation in African Monkeys" provides a valuable resource for researchers and scientists in the fields of anthropology, primatology, zoology, and conservation biology.
