Socio-bioenergetics and sexual dimorphism in primates

Socio-bioenergetics is presented as a practical method of estimating energy budgets of primates in a social context. Energy budgets are estimated on the basis of behavioral observations and a series of empirical formulae, which consider body weight, activity, and reproductive status. Data on a captive colony of Sykes' monkeys and baboons are incorporated as illustrations of the possible effects of group composition, body size, reproductive status, and activity patterns on energy requirements.Supported by the Wenner-Gren Foundation for Anthropological Research Incorporated and the National Science Foundation Grant GU-1598.
