Exploring personality axes and their morpho-physiological correlations in captive capuchin monkeys
Big five; individual differences; morphological measures; cortisol.
Animal personality can be defined as consistent behaviors through time and contexts, and this is documented in all animal kingdom, both in captivity or natural environment. However, studies approaching the relation between behaviors patterns and morphological and physiological parameters offer controversial results, possibly due to methodological differences. In this research we will explore differences in the behavior profile using capuchin monkeys (Sapajus sp.) as a model. The behavior of 24 animal will be recorded, totaling five hours for each subject, along with an expectation of 100 fecal samples. We will explore the following hypothesis 1: It is possible to observe conserved personality axis in Capuchin-monkeys. And 2: Behavioral differences correlate with morphological and hormonal profile. The preliminary analyses offer support to the second hypothesis, with correlations between facial morphology and hormonal profile. Throughout the text we show some preliminary analysis of these set of variables.
