灵长类动物的异理行为已经获得了超越其原始卫生功能的重要社会功能，并且可以交换自身或用作货币以获得其他利益，例如交配，获得婴儿或竞争支持。我们探讨了战略使用的梳理作为一种社会工具，在半野生金丝猴（Rhinopithecus roxellana）在中国中部，一个物种，其中两个理想的资源，即生殖男性和婴儿，仅限于交配和出生季节，分别。我们预测，雌性会根据个体的“价值”，有选择地对不同的个体进行梳理。我们的研究结果表明，在交配季节，女性致力于更多的梳理居民男性比在出生季节，这种影响是特别强烈的非母亲（女性没有新生儿）。此外，女性更有可能新郎的居民男性交配后，比在基线的社会条件。在出生季节，雌性比在交配季节更多地为其他雌性梳毛，母亲（有新生婴儿的雌性）是最有价值的梳毛伙伴。非母亲对其他女性的婴儿的平均接触率显着高于梳理后的母亲比基线的社会条件。总之，我们的研究结果使人信服的概念，灵长类动物的女性使用梳理作为一种战略工具，以获得有限的资源，如男性和婴儿，并根据季节性的有价值的资源的不同偏好特定的个人。
Allogrooming in primates has acquired an important social function beyond its original hygienic function and can be exchanged either for itself or used as a currency to obtain other benefits such as copulations, access to infants or agonistic support. We explore the strategic use of grooming as a social tool in semi-wild golden snub-nosed monkeys (Rhinopithecus roxellana) in central China, a species where two desirable resources, viz. reproductive males and infants, are restricted to the mating and birth season, respectively. We predict that females expend their grooming selectively to different individuals according to their “value”. Our results show that in the mating season, females devoted more grooming to the resident male than in the birth season, and this effect was particularly strong in non-mothers (females without newborn infants). Moreover, females were more likely to groom the resident male after copulation than during baseline social conditions. In the birth season, females devoted more grooming to other females than in the mating season, and mothers (females with newborn infants) were the most valuable grooming partners. The mean rate of contact by non-mothers toward infants of other females was significantly higher after grooming the mothers than in baseline social conditions. In conclusion, our findings lend credence to the notion that primate females use grooming as a strategic tool to obtain limited resources such as males and infants and vary preference for particular individuals depending on the seasonal availability of valuable resources.
