Social determinants of physiological stress and health aspects in wild femalecrested macaques (Macaca nigra)

社会关系的质量和数量影响着人类和动物的个体死亡风险。在这方面，特别提到了社会关系对急性和慢性压力源的缓冲作用。糖皮质激素水平的长期升高已被证明会抑制免疫系统，从而增加对寄生虫和疾病的易感性，从而增加各种分类群的死亡率。此外，最近对人格的研究表明，某些人格特质也会影响个人的免疫反应和健康。然而，到目前为止，只有少数关于野生哺乳动物的研究直接调查了社会性，个性，压力水平和个体健康之间的联系。因此，在我们的研究中，我们的目的是调查这种关系在一个野生种群的高度耐受性的灵长类动物物种，冠猕猴。这项研究将通过结合对行为数据的详细分析，包括社会网络分析，以及生理压力数据和一组非侵入性收集的健康标志物进行。

The quality and quantity of social relationships influences the individual risk of mortality in humans and animals alike. The buffering effect social relationships may have on acute and chronic stressors have been particularly invoked in this respect. Chronically elevated glucocorticoid levels have been shown to suppress the immune system and, thus, to increase susceptibility to parasites and disease, and thereby mortality in a variety of taxa. Furthermore, more recent studies on personality suggest that certain personality traits also impact individual immune response and healthiness. However, only a few studies on wild mammals have so far directly investigated the link between sociality, personality, stress levels and individual health. In our study, we therefore aim at investigating this relationship in a wild population of a highly tolerant primate species, the crested macaque. The study will be carried out by combining detailed analysis of behavioural data, including social network analysis, with data on physiological stress, and from a set of non-invasively collected health markers.
