Sex Ratio and Local Resource Competition in a Prosimian Primate

ANNE BARRETT CLARK 1

1 Primate Behaviour Research Group, University of Witwatersrand, Johannesburg, South Africa

Competition between female kin for local limiting resources may explain a male-biased secondary sex ratio in the prosimian Galago crassicaudatus. Data demonstrating the skewed sex ratio, a brief summary of field observations on the species, and a simple mathematical statement of the hypothesis are presented. Local resource competition may influence sex ratio in other mammals.
