PERSONALITY TRAITS AND SOCIAL INTERACTIONS IN CAPTIVE CAPUCHIN MONKEYS (SAPAJUS SPP)

Resumo

<p>Inter-individual differences in animal behaviors pattern, or personality, influence dispersal tendencies, survivorship, disease resilience and social interactions. Capuchin monkeys, a neotropical primate, show a repertoire of complex behavior, such as tool use and triadic awareness. Previous studies indicate that capuchin monkey dyads with similar personalities form better quality relationships. In this study we investigate the influence of personality on social interactions and social network indexes in 25 captive individuals of <em>Sapajus spp.</em> housed in recue center of CETAS / IBAMA - RN. Between January and June of 2018, we collected 46 hours of observations of all occurrences of social behavior (affiliation and agonism) and proximity between individual for analyses of social network. We attribute individual´s personality using Hominoid Personality Questionnaire. Relation between personality, social interactions and network were analyzed using regression models selected via Akaike Information Criterion. Our results show that: 1) high score in Sociability predicts less involvement in agonistic interactions (β= -0,754; p = 0,019); 2) high score in Openness predicts more involvement in agonistic interactions (β= 0,543; p = 0,064); 3) high score in Neuroticism predicted high clustering (β= 0,124; p = 0,006); 4) high score in Attentiveness tended to lower clustering (β= -0,090; p = 0,062). These results suggest that personality traits predicts social interaction patterns. Sociability did not predict affiliation but predict decreased involvement in conflicts. Open individuals were more involved in agonism, probably due to high exposure to new situations or social partners. The relation between high Neuroticism and clustering may be related to support seek by these individuals. Conversely, very attentive individuals were less clustered suggesting a distribution of this attention to many partners or towards non-social signals. These data reveal that studies on personality traits may help in management of captive colonies.</p>
