Spatial structure in Mangabey groups

The spatial order of mangabey age-sex classes in progressions across canopy gaps was found to resemble strongly that of baboons. Greater peripherality of adult males (particularly dominant males) and centrality of independent juveniles characterized intragroup spatial structure whether the predominant group activity was feeding, social interaction, or movement. The similarities in spacing, despite striking differences in the number and nature of predators, between arboreal, forest mangabeys and terrestrial, open-country baboons suggest that intragroup spatial structure responds to factors other than predation.
