Sexual dimorphism in the activity of Olive baboons (Papio cynocephalus anubis) housed in monosexual groups.
In this study, responses to the formation of social groups were compared between adult male and female Papio cynocephalus anubis. Quantitative behavioral data based on systematic focal animal sampling were used to test the hypothesis that adult male and female olive baboons are similar in their behavioral response to (1) the formation of monosexual social groups and (2) the simultaneous reduction of social unit and habitat size. Males and females differed (t test, p less than 0.05) in performance of sexual, tension, and stereotypy behavior during large group formations. During small group formations, males and females differed in play, subordinate, locomotion, manipulation, sexual, tension, and stereotypy behavior. Our observations, clearly indicate that in captivity, under conditions of identical housing, social structure, and social unit history, males and females differ in their behavior performance. Our data suggest that some socioenvironmental conditions, such as the lack of heterosexual grouping, may exaggerate those differences.
