Field studies of endocrine function in a range of social mammals suggest that high dominance rank is commonly associated with elevated glucocorticoid production. This is puzzling, because in stable dominance hierarchies, high status is normally associated with social control and predictability, key predictors of low psychological stress. One solution to this problem may be that high rank is commonly associated with elevated energetic expenditure, leading to increased metabolic stress and… 
Urinary Cortisol, Aggression, Dominance and Competition in Wild, West African Male Chimpanzees
The findings suggest that male chimpanzees adjust competitive behavior to context dependent conditions, possibly by means of predictability of outcomes of social interactions, and use conflict management strategies, such as avoidance of aggression potentially diminishing the risk of escalation.
Social relationship and hair cortisol level in captive male chimpanzees (Pan troglodytes)
The results show that not only aggressive interactions but also overall social situations in which animals do not have balanced relationships with others might result in the long-term elevation of cortisol levels in captive male chimpanzees.
Single Aggressive Interactions Increase Urinary Glucocorticoid Levels in Wild Male Chimpanzees
It is concluded that aggressive behaviour is costly for both aggressor and victims and that costs seem poorly explained by energetic demands of the interaction, since both aggressors and victims experience a stress response to conflict.
Social correlates of variation in urinary cortisol in wild male bonobos (Pan paniscus)
Maternal Behavior and Physiological Stress Levels in Wild Chimpanzees (Pan troglodytes schweinfurthii)
The results generally agree with the suggestion that elevated GC concentrations are related to maternal motivation and responsivity to infant cues and are the first evidence of a hormonal correlate of maternal behavior in a wild great ape.
Urinary cortisol responses to unusual events in captive chimpanzees (Pan troglodytes)
A lack of a urinary cortisol response to events hypothesized to result in increases in cortisol may indicate that the events were not actually stressful for the chimpanzees, but may have resulted from the limited temporal resolution of measuring cortisol excretion as an indicator of integrated secretion, or from changes in rates of agonistic behaviors.


Cortisol concentrations and the social significance of rank instability among wild baboons
Biochemical and hormonal correlates of dominance and social behavior in all‐male groups of squirrel monkeys (Saimiri sciureus)
The association between WBS and dominance rank previously reported in Old World monkeys to a New World monkey species is extended, support previous suggestions that mean T and C titers are not reflective of dominance rank in well‐established groups, and indicate that dominance rank affects adrenocortical response to the stress associated with capture and anesthesia.
Noninvasive Stress and Reproductive Measures of Social and Ecological Pressures in Free‐Ranging African Elephants
It is suggested that measures of progesterone and corti- sol metabolites in feces provide indices of reproductive function and physiological stress that can quantify both natural and human disturbances in African elephants.
Endocrine Correlates of Rank, Reproduction, and Female-Directed Aggression in Male Japanese Macaques (Macaca fuscata)
The data further support the contention that social subordinance and stress are not inexorably linked, as well as suggest that elevated glucocorticoid concentrations in high-ranking males may reflect increased metabolic costs associated with dominant male reproductive strategy.

Dominance, aggression and testosterone in wild chimpanzees: a test of the ‘challenge hypothesis’
A preliminary investigation of urinary testosterone and cortisol levels in wild male mountain gorillas
The results suggest that the increase in testosterone associated with puberty occurs prior to any outward sign of development of secondary sexual characteristics, and suggests that subordinate males are not socially stressed, at least as measured by cortisol.
Diurnal patterns of urinary steroid excretion in wild chimpanzees
It is suggested that if a small number of samples are to be used to characterize an individual's basal steroid levels, afternoon samples may be preferable because they show less intra‐individual variability.
