This book, with five editors and 46 contributors, is an important scholarly compilation of current knowledge of primate behavior under wild conditions. Its creation was prompted by the burgeoning of primate studies and the increasingly endangered status of many primate species. The 40 articles are arranged in five sections: a systematic treatment of behavior by taxonomic group; behavior related to ecological conditions; social interactions; communication and intelligence; and the future of primate research. The book will most likely appeal to researchers, students, zoo managers and others who maintain captive primates, and those who seek to use primate behavior to elucidate that of humans. In view of the vast, complex data, the latter will find no simple interpretations.
