The dangers of multi-male groupings: trauma and healing in cercopithecoid monkeys from Cameroon
This study examines the potential linkage between social organization and trauma in a sample of cercopithecids from Cameroon. Skeletal trauma is described in a museum collection of eight sympatric monkey species. Macroscopic analysis was carried out on a total of 139 complete skeletons of mangabeys, colobines and guenons. Species in multi-male groups were found to have higher fracture frequencies than those in uni-male groups. These higher frequencies may be related to intra-specific male–male aggression; however, similarities in fracture patterning between males and females in multimale groups suggest that other factors may be involved. Although fracture etiology may not be identified with certainty, this study suggests that predation may indirectly be a cause of traumatic injuries in those species of cercopithecid monkeys displaying multi-male social organizations. The data presented also highlight the utility of museum collections as an additional resource in analyses of primate behavior, demonstrating that behavioral information does not die when the animal does.
