笼养熊猴等级结构及其对育婴影响的研究

通过记录繁殖笼养熊猴(Macaca assamensis)成员之间发生攻击和屈服行为的指向和次数,采用计算优势指数的方法,判断笼内各成员的等级排列,并通过论述成年猴间的亲疏行为来探讨对育婴的贡献。结果表明:笼养的熊猴个体之间存在明显的等级序位,个体所处的序列位置与它的体重成正相关,等级序位的高低是通过暴力手段来确立的;雌猴的序位高低不影响其性权利,雄猴常常采用暴力的方式进行强行交配,雌猴处于一种被动接受的状态;育婴主要由母亲猴完成,但雄性对幼体也有明显的照料行为,照料的多少与雌猴所处的序位无关而与雌猴受雄猴性偏爱程度有关;阿姨猴对育婴贡献甚微,仅是象征性的作用。

Ranking structure among Macaca assamensis and effect on raising infant in breeding cages

All the data of object and frequency about aggressive and submissive behavior between Macaca assamensis in a breeding cage were calculated with the method of dominance index to judge ranking structure among them.In addition,the connection between the contribution for training infant and the ranking structure was researched.The effect showed that there is obvious ranking among M.assamensis.Their status were positively related with their weight and their hierarchies were conformed through violent fighting.The females' ranking didn't affect their mating because the male often forced to mate with them and the female belong to passive reception.The task for caring infants was mainly for the mother,but male often take part in infant caring and the degree of caring related with sex favoriation and not the dominance of females.Other females contribution for raising infant is very little.
