Amazon.com description: Product Description: This is the first resource in forty years which reviews the latest writings and research dealing with prosimians and new world primates. There are few books available that deal with primate ecology and the behavior of free-ranging primates, organized by taxonomic groups. This volume represents the most in-depth coverage, initially characterizing these animals as they exist in their least disturbed state, then comparing behavior in disturbed situations and captivity in order to gain a better understanding of primate behavior and primate communities. Each major taxonomic group is covered, including information on locomotion and habitat, activity cycles, predation, social organization, communication, reproduction and infant development. Well illustrated with over 70 figures and plates.
