项目摘要

Japanese macaques have the matrilineal social structure, and the life history of females has been studied more than 50 years. But non-troop males have been scarcely studied because of the difficulty of the pursuit in the wild. The purpose of this study makes clear the life history of males.Results of this study are as follows : 1)There are two stages in the non-troop males ; troop-following male and non-following male. 2)There are also two stages in the non-following male ; solitary male and male-group male. 3)The ratio of troop male, troop-following male and non-following male is 2:3:3. 4)Young males aged from 4 to 10 years old live in the male-group and old males aged over 15 years old live in solitary. 5)Stable male-group is formed based on males of same age or same generation of the same troop. 6)The highest aged male leaves the male-group and begins to follow the troop movement in breeding season. 7)The lowest aged male of the male-group often returns back to his natal troop. 8)This male takes out younger males of his troop to the male-group, and it is the main mechanism of emigration. 9)The age of male emigration from the natal troop is most frequently from 4 to 6 years old in Kinkazan population. 10)Length of stay in the troop of immigrant males varies from 1 to 8 years. 11)Throughout his life, the male immigrates only one or two other troops.From these results, it is possible to describe roughly the life history of the male Japanese macaques.
日本猕猴具有母系社会结构,雌性猕猴的生活史研究已有50多年的历史。但是,由于在野外很难追捕,很少对非群居的雄性进行研究。本研究的目的是弄清雄鸟的生活史,研究结果如下:1)非部队雄鸟的生活史可分为跟随部队雄鸟和不跟随部队雄鸟两个阶段。2)非跟随雄性也有两个阶段:孤独雄性和雄性群体雄性。3)部队雄性、部队跟随雄性和非跟随雄性的比例为2:3:3。4)4至10岁的年轻男性生活在男性群体中,15岁以上的老年男性独居。5)稳定的雄性群体是以同一群体的同龄或同代雄性为基础形成的。6)最高年龄的雄性在繁殖季节离开雄性群体并开始跟随群体运动。7)雄性群体中年龄最低的雄性经常回到他的纳塔尔群体。8)这只雄鸟把自己族群中较年轻的雄鸟带到雄性族群中,这是迁徙的主要机制。9)在金刚山人口中,男性从纳塔尔群体迁出的年龄最多,为4 - 6岁。10)在男性移民队伍中的停留时间从1年到8年不等。11)从这些结果可以大致描述雄性日本猕猴的生活史。
