A great deal has been written about primates; however few volumes have focused on an entire community of sympatric monkeys at a single site. Drawing upon diverse sets of data, the authors provide a multi-thematic case study of the entire monkey community of the Tai forest (Ivory Coast). Much of the book explores how the seven monkey species have adapted to hunting pressures from chimpanzees, leopards, crowned eagles and humans. Other themes covered include feeding ecology, social behaviour, positional behaviour and habitat use, vocal communication and conservation. Colour photographs of all species are provided, showing the major behavioural characteristics of each, as little is known about these West African monkeys. This scientifically important volume will be of interest to a broad audience including primatologists, functional anatomists, psychologists, and behavioural ecologists.

Studies of sexual selection, interspecific mutualism, and intraspecific cooperation show that individuals exchange commodities to their mutual benefit. The exchange values of commodities are a source of conflict, and behavioral mechanisms such as partner choice and contest between competitors determines the composition of trading pairs or groups. These "biological markets" can be examined to gain a better understanding of the underlying principles of evolutionary ecology. In this volume scientists from different disciplines combine insights from economics, evolutionary biology, and the social sciences to look at comparative aspects of economic behavior in humans and other animals.

Since the development of game theory, the analysis of animal behaviour using the theories of economics has become a growing field of biological research in which models of games and markets play an important role. Studies of sexual selection, interspecific mutualism and intraspecific cooperation show that individuals exchange commodities to their mutual benefit; the exchange values of commodities are a source of conflict, and behavioural mechanisms such as partner choice and contest between competitors determines the composition of trading pairs or groups. These 'biological markets' can be examined to gain a better understanding of the underlying principles of evolutionary ecology. In this volume scientists from different disciplines combine insights from economics, evolutionary biology and the social sciences to look at comparative aspects of economic behaviour in humans and other animals. Aimed primarily at evolutionary biologists and anthropologists, it will also appeal to psychologists and economists interested in an evolutionary approach.
