Evolutionary Biology and Conservation of Titis, Sakis and Uacaris

About this book

The neotropical primate family Pitheciidae consists of four genera Cacajao (uacaris), Callicebus (titis), Chiropotes (bearded sakis) and Pithecia (sakis), whose 40+ species display a range of sizes, social organisations, ecologies and habitats. Few are well known and the future survival of many is threatened, yet pitheciines have been little studied. This book is the first to review the biology of this fascinating and diverse group in full. It includes fossil history, reviews of the biology of each genus and, among others, specific treatments of vocalisations and foraging ecology. These studies are integrated into considerations of current status and future conservation requirements on a country-by-country basis for each species. A state-of-the-art summary of current knowledge, Evolutionary Biology and Conservation of Titis, Sakis and Uacaris is a collective effort from all the major researchers currently working on these remarkable animals.

Biography

Adrian Barnett is an Honorary Research Fellow at the Instituto National de Pesquisas da Amazonas in Manaus, Brazil, and at the Centre for Research in Evolutionary and Environmental Anthropology at Roehampton University. He is a tropical biologist whose research focuses on rare, little-known and hard-to-find species and has spent fifteen years studying tropical primates, particularly the conservation and ecology of uacaris.

Liza M. Veiga is a postdoctoral fellow at the Federal University of Para and the Emilio Goeldi Museum, both in Belem, Brazil. Her research focuses on the conservation biology of the genus Chiropotes, Brazil.

Stephen F. Ferrari is a Professor of Zoology in the Biology department of the Federal University of Sergipe, Sao Cristovao, Brazil. While his research covers a wide variety of mammalian taxa, he has a particular focus on the primate genera Callicebus and Chiropotes, their ecology and conservation.

Marilyn A. Norconk is Professor of Anthropology at Kent State University, Kent, OH, USA. Her research focuses on behavioral ecology of South American monkeys, particularly feeding ecology and social behaviour of white-faced sakis and bearded sakis in Venezuela and Suriname.
