About this book

Contains the most comprehensive theoretical approach to behavioural ecology, coupled with quantitative methods that will underpin future work in the field. It identifies social foraging as an economic interaction between the actions of individuals and those of other foragers. This interdependence raises complex questions about the size of the foraging groups, the diversity of resources used, and the propensity of group members to exploit each other or forage cooperatively. The models developed in the book will allow researchers to test their own approaches and predictions.

Social Foraging Theory will stimulate and guide future work on the evolution and ecology of group foraging for years to come. -- Graeme D. Ruxton Book Reviews This book will surely have a major influence on the field of behavioral ecology for years to come ... To offer a shameless directive, if you have any interest in the evolution of social behavior, do yourself a favor and read this book. -- Thomas A. Waite Ecology This book's] framework is so useful and insightful that I expect it to be very widely used. I find it hard to imagine how the authors of any future paper published on the foraging of animals in groups could get away without citing this work. I think it will become a classic text. -- Graeme D. Ruxton Ethology A well-written, extensive, and unique review of the theoretical model developed to predict and explain the foraging behaviors of animals while in groups... Behavioral ecologists specializing in animal foraging will find this book to be an indispensable resource. -- Craig L. Frank Quarterly Review of Biology In what is certain to become a landmark publication, Luc-Alain Giraldeau and Thomas Caraco present a frame that links differing ecological questions that, to date, have rarely been related. -- Michael Gillingham ISBE Newsletter
