项目摘要

The present study focused on relations between social behavior patterns and maternal styles of adult females in a free-ranging group of Japanese macaques, and on long-term social relationships of adult females with other group members and their maternal behaviors in a captive group of lowland gorillas. Based on social grooming performed by female Japanese monkeys, I found that they were very likely to concentrate their grooming interactions on closely related females and certain familiar unrelated females, while they also showed progressive trait for grooming since they formed grooming relationships with new partners. I also reported some maternal behaviors which might rarely occur in a wild situation: An adult female carried her newborn ventrally and her yearling dorsally at the same time. After two females lost their own newborn infants, they allowed their yearlings to suckle. These observations show a higher ability and flexibility of maternal behaviors in female Japanese monkeys.Ba … More sed on long-term observations on a captive group of gorillas, I also reported some interesting cases which might not usually occur. After infant-swapping between a primiparous mother with a neonate and a multiparous mother with a 10-month-old infant, the mothers provided appropriate maternal care including nursing to their adopted infants, but the older infant still sought refuge with its biological mother more frequently than with its foster mother. Almost two years later, the younger infant who was weaned by its foster mother began nursing from its biological mother, who subsequently weaned her adopted infant. Then, the older infant who was weaned exhibited abnormal plucking hair behavior. These results indicate that it was difficult for the gorilla infant to quickly transfer its attachment figure from the mother to another adult female when the mother continued to remain in the group. I also reported repeated acts of baby-transfer between an experienced mother and her young adult females, indicating that the mother encouraged her inexperienced daughter by rectifying inappropriate maternal behavior toward the baby.

本研究的重点是社会行为模式之间的关系和母性风格的成年女性在一个自由放养的日本猕猴群体，和长期的社会关系的成年女性与其他群体成员和他们的母性行为在一个圈养的低地大猩猩群体。基于雌性日本猴的社会理毛行为，我发现它们很可能将它们的理毛互动集中在近亲雌性和某些熟悉的无关雌性身上，同时它们也表现出进步的理毛特征，因为它们与新的伴侣形成了理毛关系。我还报道了一些在野外很少发生的母性行为：一只成年雌性同时腹抱新生儿和背抱一岁的幼崽。在两名女性失去了自己的新生婴儿后，他们允许他们的一岁鸽交配。这些观察结果表明，雌性日本猴的母性行为能力和灵活性较高。 ...更多信息在对一群圈养的大猩猩进行长期观察后，我还报告了一些可能不常发生的有趣案例。在一位带着新生儿的未生育母亲和一位带着10个月大婴儿的经产母亲之间进行婴儿交换后，母亲提供了适当的产妇护理，包括对她们收养的婴儿进行护理，但年龄较大的婴儿仍然比其养母更频繁地寻求其亲生母亲的庇护。大约两年后，由养母断奶的年幼婴儿开始由亲生母亲哺乳，亲生母亲随后为她的养子断奶。然后，断奶的大婴儿表现出异常的拔毛行为。这些结果表明，当母亲继续留在群体中时，大猩猩婴儿很难迅速将其依恋形象从母亲转移到另一只成年雌性。我还报告了一位有经验的母亲和她年轻的成年女性之间反复发生的婴儿转移行为，这表明母亲通过纠正母亲对婴儿的不当行为来鼓励她没有经验的女儿。少
