Primate Societies is a synthesis of the most current information on primate socioecology and its theoretical and empirical significance, spanning the disciplines of behavioral biology, ecology, anthropology, and psychology. It is a very rich source of ideas about other taxa. "A superb synthesis of knowledge about the social lives of non-human primates."—Alan Dixson, Nature

Moral Sentiments and Material Interests presents an innovative synthesis of research in different disciplines to argue that cooperation stems not from the stereotypical selfish agent acting out of disguised self-interest but from the presence of "strong reciprocators" in a social group. Presenting an overview of research in economics, anthropology, evolutionary and human biology, social psychology, and sociology, the book deals with both the theoretical foundations and the policy implications of this explanation for cooperation. Chapter authors in the remaining parts of the book discuss the behavioral ecology of cooperation in humans and nonhuman primates, modeling and testing strong reciprocity in economic scenarios, and reciprocity and social policy. The evidence for strong reciprocity in the book includes experiments using the famous Ultimatum Game (in which two players must agree on how to split a certain amount of money or they both get nothing.)

Over the past century, we have made great strides in reducing rates of disease and enhancing people's general health. Public health measures such as sanitation, improved hygiene, and vaccines; reduced hazards in the workplace; new drugs and clinical procedures; and, more recently, a growing understanding of the human genome have each played a role in extending the duration and raising the quality of human life. But research conducted over the past few decades shows us that this progress, much of which was based on investigating one causative factor at a time—often, through a single discipline or by a narrow range of practitioners—can only go so far. Genes, Behavior, and the Social Environment examines a number of well-described gene-environment interactions, reviews the state of the science in researching such interactions, and recommends priorities not only for research itself but also for its workforce, resource, and infrastructural needs.

As our closest evolutionary relatives, nonhuman primates are integral elements in our mythologies, diets and scientific paradigms, yet most species now face an uncertain future through exploitation for the pet and bushmeat trades as well as progressive habitat loss. New information about disease transmission, dietary and economic linkage, and the continuing international focus on conservation and primate research have created a surge of interest in primates, and focus on the diverse interaction of human and nonhuman primates has become an important component in primatological and ethnographic studies. By examining the diverse and fascinating range of relationships between humans and other primates, and how this plays a critical role in conservation practice and programs, Primates Face to Face disseminates the information gained from the anthropological study of nonhuman primates to the wider academic and non-academic world.

This collection of 29 papers grew out of a symposium entitled "Setting the Future Agenda for Neotropical Primates. " The symposium was held at the Department of Zoo logical Research, National Zoological Park, Washington D. C. , on February 26-27, 1994, and was sponsored by the Wenner-Gren Foundation for Anthropological Research, Smith sonian Institution, and Friends of the National Zoo. We put the symposium together with two objectives: to honor Warren G. Kinzey for his contributions to the growing field of platyrrhine studies and to provide researchers who work in the Neotropics with the oppor tunity to discuss recent developments, to identify areas of research that require additional study, and especially to help guide the next generation of researchers. The symposium provided the opportunity to recognize Warren as a mentor and col laborator to the contribution of the study of platyrrhines. Contributions to the book were expanded in order to provide a more comprehensive view of platyrrhine evolution and ecology, to emphasize the interdisciplinary nature of many of these studies, and to high light the central role that New World monkeys play in advancing primatology. If this vol ume were to require major revisions after just one more decade of research, that would be a fitting testament to Warren's enthusiasm and his drive to continually update the field with new ideas and methods. Tributes to Warren and a list of his publications have been published elsewhere (Norconk, 1994, 1996; Rosenberger 1994, 1995).
