Patch Occupation Time Predicts Responses by Grey-Cheeked Mangabeys ( Lophocebus albigena) to Real and Simulated Neighboring Groups.

- Abstract
When two social groups are close enough to hear each other's short-range vocalizations but not yet close enough to see each other, they can choose whether to approach to initiate a direct contest. In this study, I evaluated whether expected payoffs and group resource-holding potential affected the likelihood of approach toward a neighboring group during naturally occurring intergroup interactions and experimental playback trials by grey-cheeked mangabeys ( Lophocebus albigena). Females approached calling groups at low rates, and only if males did so as well. Groups that had recently arrived (≤30 min) at the interaction location were more likely to approach than groups that were in the interaction location for >30 min. Site residency likely indicates the degree of short-term, local resource exploitation, and explains this pattern of patch defense. There was no evidence that mangabeys defended home range core or peripheral areas, that males defended female mates, or that infant defense affected the likelihood of approach. Surprisingly, resource-holding potential had no effect on patterns of contest initiation, but may influence other aspects of intergroup contests. The unexpected importance of payoff asymmetries, relative to asymmetries in resource-holding potential, points to the need for an expanded theoretical framework.
