Effect of mating activity and dominance rank on male masturbation among free-ranging male rhesus macaques.
The adaptive function of male masturbation is still poorly understood, despite its high prevalence in humans and other animals. In non-human primates, male masturbation is most frequent among anthropoid monkeys and apes living in multimale-multifemale groups with a promiscuous mating system. In these species, male masturbation may be a non-functional by-product of high sexual arousal or be adap...
متن کاملDominance rank and reproductive maturation in male rhesus macaques (Macaca mulatta).
The timing of reproductive maturation in females has been linked to differences in dominance status and exposure to males, but less information is available regarding the effect of dominance rank and exposure to females on the pace of reproductive maturation in males. A two-year study of a cohort of nine male rhesus macaques was undertaken to document potential social factors influencing variat...
متن کاملFamiliarity affects the assessment of female facial signals of fertility by free-ranging male rhesus macaques.
Animals signal their reproductive status in a range of sensory modalities. Highly social animals, such as primates, have access not only to such signals, but also to prior experience of other group members. Whether this experience affects how animals interpret reproductive signals is unknown. Here, we explore whether familiarity with a specific female affects a male's ability to assess that fem...
متن کاملEffects of reproductive condition and dominance rank on cortisol responsiveness to stress in free-ranging female rhesus macaques.
The hypothalamic-pituitary-adrenal (HPA) axis modulates individuals' physiological responses to social stress, which is an inevitable aspect of the daily lives of group-living animals. Previous nonhuman primate studies have reported that sex, age, rank, and reproductive condition influence cortisol levels under stressful conditions. In this study we investigated cortisol responses to stress amo...
متن کاملSocial correlates of the dominance rank and long-term cortisol levels in adolescent and adult male rhesus macaques (Macaca mulatta)
A common pattern in dominance hierarchies is that some ranks result in higher levels of psychosocial stress than others. Such stress can lead to negative health outcomes, possibly through altered levels of stress hormones. The dominance rank-stress physiology relationship is known to vary between species; sometimes dominants show higher levels of glucocorticoid stress hormones, whereas in other...
