Captive animals of several species change their behavioral pattern and hormonal profile in response to physical (for example, cage size and temperature) and social (for example, group size and social isolation) modification of their environment. To evaluate the effect of environmental change in captivity, the affiliative (contact/proximity and allogrooming) and individual (approach, leaving, scent mark, locomotion, and autogrooming) behavior of five family groups of common marmosets, Callithrix jacchus, were recorded on weekdays (non-quiet) and at the weekend (quiet) for two months. In addition, fecal samples were collected for four of these groups to measure their cortisol levels under both conditions. The behavioral pattern and hormonal profile of breeding pairs and their offspring were modified by different management routines used in the experimental conditions. We found that the animals spent more time in affiliative interactions at the weekend, whereas on weekdays, they showed more individual behaviors. Moreover, cortisol levels of breeding pairs and their offspring were higher on weekdays, suggesting that common marmosets living in captivity react to environmental modification by changing their behavioral and hormonal pattern.
