社会等级制度普遍存在于动物社会中，影响动物的内分泌功能和行为。在非人类灵长类动物中，社会等级和皮质醇水平之间的关系因物种而异，甚至在物种内部也不同。在这里，我们评估了成年雄性太行山猕猴(恒河猴，猕猴)的社会地位和粪便皮质醇水平的关系，这些成年雄性太行山猕猴来自五龙口-2(WLK-2)组，生活在五龙口风景区、济源、中国。2014年3月至5月，我们从8只成年雄性太行山猕猴身上采集了54份新鲜粪便样本，记录了195种激惹行为。根据激励性行为矩阵对男性进行社会等级分配，然后用酶联免疫吸附试验测量粪便样本中的皮质醇浓度。我们发现WLK-2组中的8只雄性太行山猕猴的社会等级遵循严格的线性等级，低等级雄性猕猴的粪便皮质醇水平显著高于优势个体，且变化更大。年龄与社会等级或粪便皮质醇水平没有显著相关性。我们的结果表明，WLK-2组中的社会等级和社会等级的维持是一种慢性应激源，低等级男性相对于优势男性保持着更高的压力水平和更大的反应范围。这为社会环境影响内分泌功能的理论提供了新的支持。
Social hierarchy commonly exists in animal societies, affecting both the endocrine functioning and the behavior of animals. In nonhuman primates, the relationship between social rank and cortisol levels varies across species and even within species. Here, we assessed the relationships between social rank and fecal cortisol levels in adult male Taihangshan macaques (rhesus macaques,Macaca mulatta tcheliensis) from the provisioned, free-ranging Wulongkou-2 (WLK-2) group inhabiting Wulongkou Scenic Area, Jiyuan, China. From March to May 2014, we recorded 195 agonistic behaviors and collected 54 fresh fecal samples from eight adult male Taihangshan macaques. Males were assigned a social rank according to an agonistic behavior matrix, and enzyme-linked immunosorbent assay was then used to measure the cortisol concentration in the fecal samples. We found that social rank among the eight male Taihangshan macaques in WLK-2 group followed a strict linear hierarchy, and that fecal cortisol levels were significantly higher and more variable in low-ranking males than in more dominant individuals. Age was not significantly associated with social rank or fecal cortisol levels. Our results suggest that social rank and maintenance of the social hierarchy within the WLK-2 group is a chronic stressor, with low-ranking males maintaining heightened stress levels and enlarged reactive scope relative to dominant males. This provides new support for the theory that social environment can influence endocrine functioning.
