Introduction

Socioecology emerged as a subdiscipline of behavioral ecology in the 1960s examining systematic relationships between ecology and social behavior of animals. Using an evolutionary approach, socioecology has focused on adaptive behavioral responses of adult males and females to variation in resource size and distribution, predation risk, and the risk of sexual harassment. The main emphasis of socioecological research has been on explaining species differences in grouping structure and patterns of social relationships. The verbal model underlying the latter aspect of this framework has been extended and refined repeatedly, primarily with data from field studies of nonhuman primates. The emerging socioecological model has been applied to various taxa, but it has been criticized more recently for being too primate-centered and for not considering phylogenetic information.

General Overviews

The relationships between ecological variables and social behavior were first formalized in Klopfer 1962 and first explicitly studied by the author of Crook 1964 in African weaverbirds. Similar earlier comparative approaches focused more on the usefulness of behavioral variation as a source of phylogenetic inference. Winn 1958 focuses on darters and provides a representative example of this approach. The most influential early comparative study was Crook and Gartlan 1966 on the socioecology of primates. Classic papers that subsequently facilitated the breakthrough of this approach include Jarman 1974 and Clutton-Brock and Harvey 1977. These early studies are still widely featured in relevant textbooks, including Davies, et al. 2012. More recent summaries and critiques can be found in Clutton-Brock and Janson 2012, which also points out important gaps in theory and empirical studies.

    The first study to introduce statistical rigor to comparative analyses. An important improvement over Crook and Gartlan 1966 and highly influential for other kinds of comparative studies in evolutionary biology.

    Comprehensive review of the history and main achievements of primate socioecology. Identifies shortcomings of the assumptions and predictions of the underlying model and makes constructive suggestions for more comprehensive future studies.

    The first broad comparative test of the notion that variation in social systems across species is correlated with differences in their ecology, using data on more than ninety African weaverbirds.
