Aggression and social support predict long-term cortisol levels in captive tufted capuchin monkeys (Cebus [Sapajus] apella).

摘要: Many nonhuman primates live in complex social groups which they regularly encounter both stressors such as aggression and support that provided by long-term affiliative relationships. Repeated exposure to may result chronically elevated cortisol levels can have deleterious physical effects impaired immune function, cardiovascular disease, reduced brain function. In contrast, relationships act a buffer, dampening the release of response acute chronic stressors. Understanding how predict is therefore essential understanding situations relate health welfare. We studied this relationship 16 socially housed captive brown capuchin monkeys (Cebus [Sapajus] apella) comparing hair with behavioral measures stress (dominance rank, rank certainty, amount received) (amount affiliation centrality network group). Dominance affiliation, age were not significant predictors population. Instead, positively related received negatively group. This pattern be attributed species' tolerant dominance system availability across hierarchy.
