项目摘要

Maternal stress, defined as stress which females experience while they are pregnant, give birth, and take care of their infants through interactions with group members, was assessed both in Japanese monkeys of a free-ranging group and in those of captivity.(1)Free-ranging situation: Comparisons of female behaviors between the periods before and after giving birth were made. In the resting situation, females after giving birth, that is, mothers, tended to be less active, spend in proximity to a greater number of group members, and start less frequently than did females before giving females ( pregnant females). In the feeding situation, mothers moved and looked around less frequently than did pregnant females. These results indicate that giving birth and taking care of infants do not necessarily bring more stress on females.(2) Individually caged mother-infant pairs: Mother-infant interactions between individually caged mothers and their infants were not different from those in social groups. However, individual caging seemed to be more stressful for mothers with their infants aged 5 or more months than those having infants of less than 5 months old. This is probably related to the fact that from around the fifth month onward infants in social groups come to interact frequently with group members other than their mothers, while infants caged with only their mothers are forced to interact with mothers because of lack of other group members.(3) Capturing pregnant females of free-ranging groups and caging them may bring chronic stress on them that stressor seems to effect their maternal behavior.

母亲的压力，定义为压力的女性经历，而他们怀孕，分娩，并照顾他们的婴儿，通过与组成员的互动，在日本猴子的自由放养组和圈养。（1）自由放养情况：比较了雌性个体在分娩前后的行为变化。在休息的情况下，女性分娩后，也就是说，母亲，往往是不太活跃，花费在接近更多的组成员，并开始不太频繁，比女性之前给女性（怀孕的女性）。在喂养的情况下，母亲移动和环顾四周的频率比怀孕的女性。这些结果表明，分娩和照顾婴儿不一定会给女性带来更多的压力。(2)单独笼中的母婴对：单独笼中的母亲和婴儿之间的母婴互动与社会群体中的母婴互动没有不同。然而，单独的笼子似乎更紧张的母亲与他们的婴儿年龄在5个月或以上比那些有婴儿小于5个月大。这可能与以下事实有关：从大约5个月开始，社会群体中的婴儿开始频繁地与母亲以外的群体成员互动，而与母亲一起生活的婴儿则由于缺乏其他群体成员而被迫与母亲互动。(3)捕获自由放养的怀孕雌鼠并将其关在笼子里可能会给它们带来慢性压力，压力源似乎会影响它们的母性行为。
