title: Sexual segregation in squirrel monkeys (Saimiri sciureus): a transactional analysis of adult social dynamics.
abstract: Female agonism against males and male interventions in social transactions between the sexes are 2 explanations for the low rates of social engagement observed between male and female squirrel monkeys (Saimiri sciureus). These possibilities were evaluated by comparing the frequency, structure, and content of transactions between the sexes in 3 experimental social units: male-female pairs, single-male-multifemale groups, and multimale-multifemale groups. Affiliative transactions between the sexes occurred 3-5 times less often in multimale-multifemale groups than in male-female pairs and in single-male-multifemale groups. Intermale agonism in the multimale-multifemale groups often coincided with ongoing transactions between the sexes, whereas female agonism against males was rather uncommon in all social units. The results failed to support the female agonism hypothesis and indicate a need for more detailed studies of intermale social dynamics.
