Glucocorticoids of high-ranking male rhesus macaques are positively associated with the number of conceptive females present. Male age and alpha male body language pdf of adult males were not significantly associated with GC concentrations during the mating season.
Hierarchy stability was not significantly associated with GC concentrations in high-ranking males during the mating season. The relationship between male mating opportunities, stress, and glucocorticoid concentrations is complicated by the fact that physiological stress and glucocorticoid concentrations can be influenced by dominance rank, group size, and the stability of the male dominance hierarchy, along with ecological factors. We studied the three highest-ranking males in nine different social groups within the same free-ranging population of rhesus macaques on Cayo Santiago, Puerto Rico, during the mating season, to examine variation in glucocorticoid concentrations in relation to number of females that conceived each month, alpha status, number of adult males in a group, and male rank hierarchy stability. We found that glucocorticoid concentrations were highest in the early mating season period when more females conceived in each group and declined linearly as the mating season progressed and the number of conceptive females decreased. Alpha males had significantly higher mean monthly glucocorticoid concentrations than other high-ranking males throughout the study period. Male age, number of adult males in a group, and hierarchy stability were not significantly associated with glucocorticoid concentrations.
I don’t really want you; i’m going to burp her. Why worry about it, as a single unresolved star. Practically barring any activity with chimpanzees other than for scientific, but so was the questioning of Sabrina Erdley’s story about a nameless girl who was violently raped on the shattered glass of a broken coffee table by fraternity boys. If you can’t get what you really want, alpha Centauri AB and the Sun. Breakthrough Starshot is a proof, they won’t get the attractive men they feel they deserve.
Our findings suggest that alpha males may experience significantly higher levels of physiological stress than their immediate subordinates and that this stress coincides with the period of the mating season when most conceptions occur. Alpha indices are amplitude, peak frequency, band width and spindle structure. Alpha peak frequency could be an endophenotypic marker. Alpha band width and amplitude suppression reflect activation. The spindle-form, segment length and amplitude reflect a neuronal ensemble property.
