在群居灵长类动物中，个体经常不仅与亲属交换毛发，也与非亲属交换毛发。我们研究了在胜山自由放养的日本猕猴(Macaca Fuscata)群体中，乞讨行为对梳理交流的影响。在这项研究中，我们使用了重点动物抽样的方法，目标是14名女性。每个病灶女性的数据收集时间为15.75±2.67小时(平均15±2.67小时)。我们将雌雄配对分为三种类型：亲缘配对、关联非亲缘配对和非关联非亲缘配对。女性在为伴侣梳理毛发后引诱对方时，比不是在所有类型的伴侣中都引诱时更频繁地接受梳理。此外，当女性在引诱之前没有为她们的非亲属伴侣梳理毛发时，她们接受修饰的频率较低；之前的修饰不需要从亲属或附属的非亲属伴侣那里接受修饰。美容互惠的程度并不因亲缘或关联的非亲缘配对的雌性在美容后乞求的频率而有所不同。另一方面，与没有关系的非亲属女性相比，当她们在打扮之后频繁地乞求时，她们之间的打扮互惠更平衡。综上所述，我们的研究表明，乞讨行为促进了雌性日本猕猴的打扮交流。
In group-living primates, individuals often exchange grooming with not only kin but also non-kin. We investigated the effect of soliciting behaviors on grooming exchanges in a free-ranging Japanese macaque (Macaca fuscata) group at Katsuyama. In this study, we used a focal animal sampling method, targeting 14 females. Data were collected for 15.75 ± 2.67 (mean ± SD) hours per focal female. We classified female–female pairs into three pair types: kin pairs, affiliated non-kin pairs, and unaffiliated non-kin pairs. Females received grooming more frequently when they solicited after grooming their partners than when they did not solicit in all pair types. In addition, females received grooming less frequently when they did not groom their unaffiliated non-kin partners before soliciting; prior grooming was not needed to receive grooming from kin or affiliated non-kin partners. The degree of grooming reciprocity did not differ according to the frequency with which females in kin or affiliated non-kin pairs solicited after grooming. On the other hand, grooming reciprocity between unaffiliated non-kin females was more balanced when they solicited frequently after grooming, as compared with when they did not. In conclusion, our study suggests that soliciting behaviors promote grooming exchanges in female Japanese macaques.
