During a 28-month period, data were collected on physiological parameters and sociosexual behavior of 13 adult male members of a large mixed-sex group of stumptail macaques living in an outdoor cage. Monthly measurements of plasma testosterone, testis size, and body weight revealed no systematic seasonality. Seasonal variations did occur in branch shaking and grooming (both with low rates in winter), but not in other behaviors studied (copulation, masturbation, aggression). Dominance ranks were stable throughout the study period and were not significantly correlated with mean testosterone levels. Temporal fluctuations in behavioral frequencies did not parallel testosterone fluctuations. Interindividual differences in behavioral frequencies were often correlated with dominance rank, but not with testosterone levels.
在为期28个月的时间里，收集了生活在户外笼子里的一大群混种短尾猕猴中13只成年雄性成员的生理参数和社会性行为数据。每月对血浆睾酮、睾丸大小和体重的测量显示没有系统性的季节性变化。树枝摇晃和梳理行为（冬季发生率均较低）确实存在季节性变化，但在其他研究行为（交配、自慰、攻击行为）中未出现。在整个研究期间，优势等级保持稳定，且与平均睾酮水平无显著相关性。行为频率的时间波动与睾酮波动不平行。行为频率的个体差异通常与优势等级相关，但与睾酮水平无关。
