动物有时会与熟悉的动物一起分散（即平行扩散）。我们调查了雄性平行扩散如何影响卷尾猴接近亲属的机会。平行扩散的雄性比其他雄性更接近彼此。平行移民比单一移民有更多的亲属。平行扩散为雄性提供了与熟悉亲属合作的机会。性别-偏向性扩散会降低分散性种群中的亲缘合作和亲缘竞争。然而，当群体生活的动物进行平行扩散时，情况可能并非如此，这种情况发生在个体与其他动物一起在群体之间转移或单独迁移到包含熟悉动物的群体中。尽管这种潜在的影响亲属的合作和竞争，很少有研究彻底调查平行扩散如何影响亲属组成的群体。为了进一步了解这一主题，我们研究了平行扩散对雄性白脸卷尾猴（Cebus capucinus）接近同居亲属的影响。2006年至2013年期间，我们收集了哥斯达黎加圣罗莎区两到五个群体的人口统计和遗传数据。我们在14个短串联重复序列位点对41名女性和39名男性进行了基因分型，并计算了他们的估计相关值。大多数男性分散在平行，平行分散男性更密切相关的其他男性比。平行移民男性和纳塔尔女性居住在类似数量的同性亲属。单一的移民男性在多人组很少居住与男性亲属，他们居住的同性亲属比平行的移民男性和纳塔尔的女性。由于平行扩散提供了一个机会，男性形成长期的合作关系，熟悉的亲属，这种扩散模式应考虑到在未来的模型的社会结构的演变。
HighlightsAnimals sometimes disperse together with familiar animals (ie parallel dispersal).We investigated how male parallel dispersal affects access to kin in capuchins.Parallel dispersing males were more closely related to one another than were other males.Parallel immigrants resided with a higher number of kin than did single immigrants.Parallel dispersal offers an opportunity for males to cooperate with familiar kin.Sex-biased dispersal can reduce kin cooperation and kin competition in the dispersed sex. However, this may not be the case when group-living animals engage in parallel dispersal, which occurs when an individual transfers between groups together with other animals or immigrates alone into a group that contains familiar animals. Despite this potential effect on kin cooperation and competition, few studies have thoroughly investigated how parallel dispersal affects the kin composition of groups. To further our understanding of this topic, we investigated the effect of parallel dispersal on access to coresident kin in male white-faced capuchins, Cebus capucinus. Between 2006 and 2013, we collected demographic and genetic data from two to five groups in Sector Santa Rosa, Costa Rica. We genotyped 41 females and 39 males at 14 short tandem repeat loci, and we calculated their estimated relatedness values. The majority of males dispersed in parallel, and parallel dispersing males were more closely related to one another than were other males. Parallel immigrant males and natal females resided with a similar number of same-sex kin. Single immigrant males in multimale groups rarely resided with male kin, and they resided with fewer same-sex kin than did parallel immigrant males and natal females. Because parallel dispersal offers an opportunity for males to form long-lasting cooperative relationships with familiar kin, this dispersal pattern should be taken into account in future models of the evolution of social structure.
