Although there is extensive literature in the field of behavioral ecology that attempts to explain foraging of individuals, social foraging--the ways in which animals search and compete for food in groups--has been relatively neglected. This book redresses that situation by providing both a synthesis of the existing literature and a new theory of social foraging. Giraldeau and Caraco develop models informed by game theory that offer a new framework for analysis. Social Foraging Theory contains the most comprehensive theoretical approach to its subject, coupled with quantitative methods that will underpin future work in the field. The new models and approaches that are outlined here will encourage new research directions and applications. To date, the analysis of social foraging has lacked unifying themes, clear recognition of the problems inherent in the study of social foraging, and consistent interaction between theory and experiments. This book 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 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. Many years in development, Social Foraging Theory will interest researchers and graduate students in such areas as behavioral ecology, population ecology, evolutionary biology, and wildlife management.

Social Foraging Theory

Experts from the natural and social sciences examine the coexistence of productive and exploitative behavior strategies observable in many species at many levels. In the natural world, some agents (investors) employ strategies that provide resources, services, or information, while others (exploiters) gain advantages through these efforts. This behavior coexists and can be observed in many species and at many levels. For example, bacteria depend on the existence of biofilms to synthesize constituent proteins; cancerous cells employ angiogenesis to feed a tumor; and parents forgo vaccinating their children yet benefit from herd immunity. Two independent research traditions have developed to analyze this behavior—one couched in evolutionary theory championed by behavioral ecologists, the other in social science concepts advocated by economists. In this book experts from economics, evolutionary biology, behavioral ecology, public health, and anthropology look for commonalities in understanding and approach. The contributors consider parasitic strategies in ecological and economic terms; the governance of natural resources, with insights from “producer-scrounger models,” forest management, and game theory; human health, discussing therapeutic opportunities, public health economics, and the integration of perspectives; and behavioral, social, and institutional consequences of exploitation strategies.

L'écologie comportementale est née de la nécessité de bien comprendre la façon dont fonctionne l'évolution pour produire l'incroyable diversité des formes du vivant. Cet ouvrage, rédigé par une vingtaine de spécialistes, sous la direction de Etienne Danchin, Luc-Alain Giraldeau et Frank Cézilly, présente une initiation complète et intégrée du comportement animal. Il est organisé autour des grandes décisions que l'individu doit prendre au cours de sa vie. Les deux derniers chapitres sont consacrés aux applications de l'écologie comportementale : élaboration de stratégies pour la conservation de la biodiversité et comparaison avec les comportements humains. Des questions de réflexion complètent le cours et en fin d'ouvrage, un glossaire bilingue de 260 entrées et un index très complet permettent d'aller rapidement à l'essentiel. Ont également contribué à cet ouvrage : Thierry Boulinier, Michel Chapuisat, Jean Clobert, Michèle de Fraipont, Alfred Dufty, Régis Ferrière, Jean-François Legalliard, Mylène Mariette, Anders P. Moller, Gabriele Sorci, Marc Théry.
