While the role of ecological factors in shaping primate social systems has been a central focus for decades, less attention has been given to phylogenetic relationships and the potential role of underlying proximate mechanisms. This study aimed to investigate the relationship between one such proximate mechanism, prenatal androgen effects (PAEs), and aspects of social behavior in female nonhuman primates using the 2D:4D ratio as a proxy for PAEs and phylogenetically controlled methods. In general, female 2D:4D ratios were highest in monogamous species (low inferred PAEs) and lowest in polygynandrous and polygynous species (high inferred PAEs). 2D:4D ratios also varied with the form of polygyny/polygynandry, potentially with regard to the need for competitive over cooperative behaviors and the intensity of female reproductive competition. Species characterized by female dominance had lower 2D:4D ratios than species characterized by male dominance or codominance. There were no significant relationships between 2D:4D ratio and either degree of frugivory or group size. Relationships between 2D:4D ratios and the directional consistency index and 2D:4D ratios and rates of female–female agonism were also nonsignificant although sample sizes for both of these variables were small. Female social relationships are a manifestation of complex competitive and cooperative behaviors and the results suggest that PAEs may act as a proximate mechanism underlying the expression of certain aspects of behavior in female primates in ways that are adaptive to their social system.

产前雄激素的影响,作为支持女性非人类灵长类动物的社会行为变化的一种机制。

尽管数十年来,生态因素在塑造灵长类动物社会系统中的作用一直是人们关注的焦点,但对系统发生关系和潜在的潜在机制的潜在关注却很少。这项研究旨在调查女性非人类灵长类动物的一种近似机制,产前雄激素效应(PAE)和社会行为方面之间的关系,并使用2D:4D比率作为PAE的代用品和系统发育控制方法。通常,雌性2D:4D比例在一夫一妻制物种中最高(推断出的PAEs最低),而在多妇生殖和多性生殖物种中(推断出的PAEs高)最低。2D:4D比率也随着一夫多妻制/一妻多夫制的形式而变化,这可能与竞争对合作行为的需求以及女性生殖竞争的强度有关。以雌性优势为特征的物种的2D:4D比率要低于以雄性优势或共性为特征的物种。2D:4D比率与食欲程度或小组人数之间没有显着关系。尽管这两个变量的样本量都很小,但2D:4D比率与方向一致性指数之间的关系以及2D:4D比率与雌雄激素激动率之间的关系也无关紧要。女性的社会关系是复杂的竞争和合作行为的一种表现,结果表明,PAEs可以作为一种灵长类机制,以某种灵长类动物某些方面的表达为基础,从而以适应其社会系统的方式发挥作用。2D:4D比率与食欲程度或小组人数之间没有显着关系。尽管这两个变量的样本量都很小,但2D:4D比率与方向一致性指数之间的关系以及2D:4D比率与雌雄激素激动率之间的关系也无关紧要。女性的社会关系是复杂的竞争和合作行为的一种表现,结果表明,PAEs可以作为一种灵长类机制,以某种灵长类动物某些方面的表达为基础,从而以适应其社会系统的方式发挥作用。2D:4D比率与食欲程度或小组人数之间没有显着关系。尽管这两个变量的样本量都很小,但2D:4D比率与方向一致性指数之间的关系以及2D:4D比率与雌雄激素激动率之间的关系也无关紧要。女性的社会关系是复杂的竞争和合作行为的一种表现,结果表明,PAEs可以作为一种灵长类机制,以某种灵长类动物某些方面的表达为基础,从而以适应其社会系统的方式发挥作用。尽管这两个变量的样本量都很小,但4D比率和雌雄激素激动的比率也不重要。女性的社会关系是复杂的竞争和合作行为的一种表现,结果表明,PAEs可以作为一种灵长类机制,以某种灵长类动物某些方面的表达为基础,从而以适应其社会系统的方式发挥作用。尽管这两个变量的样本量都很小,但4D比率和雌雄激素激动的比率也不重要。女性的社会关系是复杂的竞争和合作行为的一种表现,结果表明,PAEs可以作为一种灵长类机制,以某种灵长类动物某些方面的表达为基础,从而以适应其社会系统的方式发挥作用。
