Migration of male hamadryas baboons into anubis groups in the Awash National Park, Ethiopia. At puberty, male primates show a variety of behavioral changes and, during adulthood, males of seasonally breeding species may be more aggressive during the mating season, when testosterone levels are maximal. Observations on the Evolution and Behavioral Significance of “Sexual Skin” in Female Primates. Observations on effects of neonatal castration upon sexual and aggressive behavior in the male common marmoset (Callithrix jacchus). Testosterone has an organizing influence upon the foetal brain of rhesus monkeys and may affect the development of neural mechanisms which govern aggression in males. The longer the time since the last aggressive act, the more likely this seeking-out or "appetitive behavior" will occur. This review deals with possible central and peripheral effects of androgens upon primate aggressive behavior. Endocrine aspects of social instability in the olive baboon (Papio anubis). Characterization and Social Correlates of Fecal Testosterone and Cortisol Excretion in Wild Male Saguinus mystax. This lecture isn't about human behaviour per se, but about primate behaviour in general (and animal behaviour too), since just as we can use the morphology of living primates to give us clues and insights into the morphology of human ancestors, so we hope that the behaviours of non-human primates (NHPs) will be similarly enlightening for the behaviour of our ancestors. Dominance and Immunity in Chimpanzees (Pan troglodytes). Bloomsmith and Lambeth, 2000, Harris et al., 1999, Mahoney, 1992, Schapiro and Bloomsmith, 1995), but several researchers indicate that while they may affect other behaviours (e.g. Longitudinal Gonadal Steroid Excretion in Free-Living Male and Female Meerkats (Suricata suricatta). of aggressive energy causing us to seek out appropriate eliciting stimuli in environments capable of releasing it.

The Psychoneuroendocrinology of (Sexual) Aggression. Use the link below to share a full-text version of this article with your friends and colleagues. A genetic explanation for ten-year cycles of grouse. Finally, plasma testosterone levels may alter as a function of aggression itself; thus levels decrease if male rhesus monkeys are defeated by conspecifics. Testosterone across successive competitions: Evidence for a ‘winner effect’ in humans?. The reason for all that attention is clear. Aggression in interactions of immature rhesus monkeys: components, context and relation to affiliation levels. 10.1002/1098-2337(1981)7:2<145::AID-AB2480070207>3.0.CO;2-M. Vote Now!

Is the concept of ‘personality’ relevant to the study of animal aggression?. observational behaviour and some stereotypies), on their own they have little or no … In the rhesus, preliminary evidence indicates that such pathways show some sensitivity to androgens. SA sometimes causes tissue damage, but usually the skin is not broken. Theoretically, it is possible that such changes in circulating testosterone might affect aggressive behavior via a feedback action on the brain, but the experimental evidence does not support such a view. Social housing of surplus males of Javan langurs (Trachypithecus auratus): Compatibility of intact and castrated males in different social settings. Effect of spatial crowding on aggressive behavior in a bonobo colony. Salivary Testosterone and Cortisol in Disruptive Children: Relationship to Aggressive, Hyperactive, and Internalizing Behaviors. Testosterone and Aggressive Behaviour during the Reproductive Cycle of Male Birds. Peripheral effects of androgens should also be considered. It should be remembered that very few of the 188 primate species have been studied experimentally and that great behavioral and physiological diversity occurs within the order. Mechanisms of Physical and Emotional Stress. Thus began de Waal's quiet revolution in how we discuss animal behavior, particularly the often aggressive encounters of primates. It should be remembered that very few of the 188 primate species have been studied experimentally and that great behavioral and physiological diversity occurs within the order. or Biological issues may contribute to aggressive behavior but are not a complete picture of the underlying cause. "Chimpanzees have something like ‘community concern,'" he says. Urinary testosterone metabolite levels and aggressive behaviors in male and female bonobos (Pan paniscus). Behavioral aspects of puberty in group-living stumptail monkeys (Macaca arctoides). Hormonal response to competition in human males. Many prosimians and New World monkeys use scent‐marking behaviors and, in males, androgen‐dependent chemical cues may be involved in sexual recognition and territorial behavior. Fetal gender and aggression in pregnant stumptail monkeys (Macaca arctoides). Conceptual and Methodological Problems Associated with the Study of Brain Mechanisms Underlying Aggressive Behaviour,<37::AID-AB2480060106>3.0.CO;2-7. This does not indicate a causative relationship between testosterone and aggressive responses, because castration and androgen treatments have little effect upon aggression in prepubertal or adult males of several primate species. Psychopharmacology of Anxiolytics and Antidepressants. This might occur because neural events associated with giving (or receiving) aggression also influence pituitary function and hence alter gonadal testosterone secretion. In the end, de Waal believes, the evolution of humans and other primates may point more toward such altruism and cooperation than a ruthless survival of the fittest.
