少数哺乳动物物种生活在一个模块化或多层次的社会中，在这种社会中，几个单独的社会/生殖单位被称为单雄单位（omu），嵌入在一个大的凝聚力的群体中。影响波段组成和稳定性的因素了解甚少。在本研究中，我们考察了亲属关系在濒危金金丝猴（Rhinopithecus roxellana）种群多层次社会形成和维持中的作用。从2005年到2011年，我们获得了生活在8-10个omu群中的86个个体（包括88.9%的雄性领袖和80.5%的成年雌性）的遗传样本。我们使用微卫星基因分型来确定亲缘关系和个体转移模式。我们发现，生活在同一OMU中的成年雌性之间的亲缘关系比随机抽取的一组雌性之间的亲缘关系更密切，而且雌性倾向于分散到含有雌性亲属的OMU中。此外，被转移的成年雌性与前任雄性领导的关系并不比与新OMU的雄性领导的关系更密切。这些结果支持了这样一种观点，即亲缘关系通过影响雌性留在当前的OMU或在转移期间进入新OMU的决定，对这种灵长类多层次社会的形成和稳定起着重要作用。[J] .中国生物医学工程学报，2015。(c) 2014 Wiley期刊公司
A small number of mammalian species live in a modular or multilevel society in which several individual social/reproductive units called one-male units (OMUs) are embedded within a large cohesive band. Factors that affect band composition and stability are poorly understood. In this study we examined the role of kinship in the formation and maintenance of a multilevel society in an endangered population of golden snub-nosed monkeys (Rhinopithecus roxellana). From 2005 to 2011, we obtained genetic samples from 86 individuals (including 88.9% of leader males and 80.5% of adult females) living in a band of 8-10 OMUs. We used microsatellite genotyping to identify patterns of relatedness and individual transfer. We found that adult females residing in the same OMU were more closely related to each other than to a random set of females drawn from the band and that females tended to disperse into OMUs that contained female relatives. In addition, adult females who transferred were not more closely related to their previous leader male than to the leader male of their new OMU. These results support the contention that kin bonds contribute importantly to the formation and stability of this primate multilevel society by influencing a female's decision to remain in her current OMU, or during transfer, which new OMU to enter.
