We describe the social relationships of young adult female Japanese macaques (Macaca fuscata) in a free-ranging troop in Arashiyama, Kyoto, Japan, who remained nulliparous beyond the ordinary age of first birth because of contraceptive administration. We observed 12 young nulliparous adult females (6-9 years old) for 270 h and 10 min from 2 February to 5 October 2010. The majority maintained close relationships with their mothers through proximity and grooming, whereas a few had very infrequent social interactions with their mothers. Most had asymmetrical grooming relationships; the grooming they received from unrelated adult females was less than the grooming they gave. Young adult females who had less frequent interactions with their mothers by either proximity or grooming received more grooming from a larger number of unrelated adult females than did those who had more frequent social interactions with their mothers. These results indicate that most young adult females who remained nulliparous beyond the ordinary age of first birth tended to maintain close relationships with their mothers, and their grooming relationships with unrelated adult females were inversely related to the degree of closeness with their mothers.
我们描述了日本京都岚山一个自由放养猴群中成年未生育雌性日本猕猴（Macaca fuscata）的社会关系。这些猕猴由于接受避孕措施，在超过正常首次生育年龄后仍未生育。2010年2月2日至10月5日，我们对12只成年未生育的年轻雌性猕猴（6 - 9岁）进行了270小时10分钟的观察。大多数猕猴通过亲近和梳理毛发与母亲保持密切关系，而少数与母亲的社交互动非常少。大多数猕猴存在不对称的梳理毛发关系；它们从无关成年雌性那里得到的梳理毛发比它们给予的要少。与母亲通过亲近或梳理毛发进行较少互动的成年年轻雌性，比那些与母亲有更频繁社交互动的雌性，从更多无关成年雌性那里得到了更多的梳理毛发。这些结果表明，大多数在超过正常首次生育年龄后仍未生育的成年年轻雌性倾向于与母亲保持密切关系，并且它们与无关成年雌性的梳理毛发关系与和母亲的亲密程度呈负相关。
