Abstract
The dominance hierarchy of female vervet and patas monkeys was similar when both used an A. drepanolobium woodland habitat. Foods here were randomly and closely distributed in space and less abundant per feeding site compared to foods in the A. xanthophloea riverine habitat, a second habitat used by vervet monkeys. The hierarchy exhibited by female vervet monkeys in the woodland habitat was not significantly linear, and the hierarchy of female patas monkeys was significantly linear only when females who had recently entered the hierarchy or had been observed for only a few months were deleted from analyses. In the A. xanthophloea riverine habitat, the dominance hierarchy of female vervet monkeys was statistically linear. Food-related competition also produced a significantly linear hierarchy among female vervet monkeys, but only when all food-related agonism was considered, including interactions that occurred in the A. drepanolobium habitat. In the riverine habitat, almost half of all female agonism among vervet monkeys was not food-related. The link between ecology and behavior at the level proposed by models of female primate social behavior (i.e., relationships) is more complex than these models ascertain. The models adequately predicted when adult female dominance relationships in patas and vervet monkeys would be nepotistic or egalitarian in a superficial sense only. Gross categorization of patterns of food availability are not adequate to explain female primate social behavior.
