RESUMO:

Allostatic load is the energetic cost an organism pays to keep optimal physiological parameters in stressful conditions, a cost that can be analyzed through glucocorticoid levels. Possible stressors include social hierarchy, social stability or factors related to captivity, such as crowding and visitor effect. The stress response may be mitigated by social support. Capuchin monkeys are excellent translational models thanks to their big neocortex and complex behaviors. They organize in tolerant matrilineal hierarchies and allogrooming is generally offered by the dominants to their subordinates. This work studies fecal metabolic glucocorticoid (FMG) levels in 48 adult capuchin monkeys located in rescue centers and zoos. We collected fecal samples for FMG analysis using ELISA method. We hypothesize that: 1) FMG levels will be higher in dominant males and subordinate females living in unstable social groups; 2) FMG levels will be higher in denser enclosures with exposure to human visitors; and 3) allogrooming has a buffering effect on stress. Partial analysis supports our hypothesis that visitor exposure and population density inside the captive enclosure are stressors capable of affecting stress levels in capuchin monkeys.
