Hormonal response to competition among male coalitions
نویسندگان
چکیده
Previous research has shown that testosterone (T) and cortisol (C) are released in response to a wide variety of social stimuli including dyadic (one on one) competitive events, but humans also compete as groups. Here we report results from a pilot study of hormonal responses to competition between male coalitions. Salivary T and C levels were assessed in adult males from a rural Caribbean village who competed at dominoes, as two-man teams, against (a) familiar men from their own village (within coalition), and (b) strangers from another village (between coalitions). Analyses indicate that both T and C levels were higher and responses more pronounced for between-village competition than for within-village competition, but we could not compare responses to victory and defeat in the betweenvillage case, since our subjects happened to win both such contests. Further studies of endocrine responses in the context of coalitional competition are warranted. D 2002 Elsevier Science Inc. All rights reserved.

This study investigates hormone response to competition and male coalitions. Coalitionary aggression may represent a fundamental human adaptation (Alexander, 1989; Wrangham, 1999). Males have complex hormone responses to competitive events (Elias 1981; Dabbs & Dabbs, 2000) that may have important effects on psychological and behavioral mechanisms involved in coalitionary competition. Withinand ...
متن کاملFactors influencing male affiliation and coalitions in a species with male dispersal and intense male–male competition, Colobus vellerosus
Male Colobus vellerosus compete intensely for access to females, which sometimes leads to mortal wounding. Yet, males often form cooperative relationships to overtake prime-aged males and immigrate into bisexual groups. We investigated the factors that predicted the presence of coalitions and affiliative relationships among males in this species. Interactions among males in 292 dyads from six g...

Behavioral plasticity within species is adaptive which directs survival traits to take multiple pathways under varying conditions. Male-male cooperation is an evolutionary strategy often exhibiting an array of alternatives between and within species. African male lions coalesce to safeguard territories and mate acquisition. Unique to these coalitions is lack of strict hierarchies between partne...
