Résumé

Examines the skewed sex ratio in Ateles spp where females disperse, and the variation in sex ratio among geographically separated sites and neighboring sites of varying productivity. The resource competition hypothesis would predict that when females disperse, animals should attempt to reduce the effect of intraspecific competition by limiting the number of male offspring produced by the community. This prediction is in agreement with the observed female biased sex ratio. Observed variability in sex ratios between populations suggests that when the potential for post-weaning resource competition is high (ie in habitats with low productivity), the community will limit the production of the non-dispersing males more than in highly productive habitats. -from Authors
