Male primates, carnivores and rodents sometimes kill infants that they did not sire. Infanticide by males is a relatively common phenomenon in these groups, but tends to be rare in any given species. Is this behavior pathological or accidental, or does it reflect a conditional reproductive strategy for males in certain circumstances? In this book, case studies and reviews confirm the adaptive nature of infanticide in males in primates, and help to predict which species should be vulnerable to it. Much of the book is devoted to exploring the evolutionary consequences of the threat of infanticide by males for social and reproductive behavior and physiology. Written for graduate students and researchers in animal behavior, behavioral ecology, biological anthropology and social psychology, this book shows that social systems are shaped not only by ecological pressures, but also social pressures such as infanticide risk.

Sexual Selection in Primates provides an account of all aspects of sexual selection in primates, combining theoretical insights, comprehensive reviews of the primate literature and comparative perspectives from relevant work on other mammals, birds and humans. Topics include sex roles, sexual dimorphism in weapons, ornaments and armaments, sex ratios, sex differences in behaviour and development, mate choice, sexual conflict, sex-specific life history strategies, sperm competition and infanticide. The outcome of the evolutionary struggle between the sexes, the flexibility of roles and the leverage of females are discussed and emphasised throughout. Sexual Selection in Primates is aimed at graduates and researchers in primatology, animal behaviour, evolutionary biology and comparative psychology.

During the past century, tropical rain forests have been reduced to about half of their original area, with a consequent loss of biodiversity. This book takes a close look at how this has happened and what the consequences may be, with an emphasis on those strategies that have proven successful in stemming the loss of plant and animal inhabitants.

The emergence of the genus Homo is widely linked to the colonization of 'new' highly seasonal savannah habitats. However, until recently, our understanding of the possible impact of seasonality on this shift has been limited because we have little general knowledge of how seasonality affects the lives of primates. This 2005 book documents the extent of seasonality in food abundance in tropical woody vegetation, and then presents systematic analyses of the impact of seasonality in food supply on the behavioural ecology of non-human primates. Syntheses in this volume then produce broad generalizations concerning the impact of seasonality on behavioural ecology and reproduction in both human and non-human primates, and apply these insights to primate and human evolution. Written for graduate students and researchers in biological anthropology and behavioural ecology, this is an absorbing account of how seasonality may have affected an important episode in our own evolution.
