ADAPTATION OF LABORATORY REARED MONKEYS TO FIELD ENVIRONMENTS

该项目涉及一组14年的纵向研究- 老恒河猴和它们的两代后代， 他们一年四季住在一个5英亩的围栏里， NIHAC。 这些14岁的成年人都是实验室出生的，手- 在托儿所长大，随后作为一个混合性别放在一起， 同辈群体 尽管这些中年人中 猴子（及其后代）有任何身体接触 自从它们第一次被移到户外， 青少年，他们一直表现出充分的恭维， 物种规范的社会行为和群体组织 到目前为止，恒河猴出生和生活在野生环境中。 在记录社会的物种规范模式的过程中， 情感发展，整体组织，以及 行为和荷尔蒙变化的季节性模式， 迄今为止已经描述了这个实验室出生的群体。 数据从 第二项对圈养出生的猴子的研究显示， 维持母系内凝聚力的基础， 野生恒河猴部队的特点，通过变化， 与出生有关的后代的首选伴侣 婴儿进入母系。 第三项研究是在过去一年开始的， 这一年的重点是青春期男性移民现象 就像在野生恒河猴群中一样。 数据从 这项半实地研究将包括定期测量身体状况， 激素成熟和下丘脑垂体肾上腺 心理生理反应的优势遭遇，此外， 在实地研究中通常获得的行为测量。

This project involves the longitudinal study of a group of 14-year- old rhesus monkeys and two generations of their progeny, all of whom live year-round in a 5-acre enclosure on the grounds of the NIHAC. The 14-year-old adults were all laboratory born, hand- reared in a nursery, and subsequently put together as a mixed-sex peer group. Despite the fact that none of these now middle-aged monkeys (nor any of their progeny) have had any physical exposure to any other monkeys, since they were first moved outdoors as juveniles they have consistently exhibited the full compliment of species-normative social behavior and group organization reported to date for rhesus monkeys born and living in feral environments. During document the species-normative patterns of social- emotional development, overall group organization, and seasonally-based patterns of behavioral and hormonal change that to date have characterized this laboratory-born group. Data from a second study of captive-born monkeys revealed a plausible proximate basis for maintenance of within-matriline cohesion, so characteristic of wild rhesus monkey troops, through changes in the preferred partners of offspring associated with the birth of an infant into the matriline. A third study initiated during the past year has focused on the phenomenon of pubertal male emigration as it occurs within wild-born rhesus monkey troops. Data from this semi-field study will include periodic measures of physical and hormonal maturation and hypothalamicpituitary-adrenal and psychophysiological response to dominance encounters, in addition to the behavioral measures typically obtained in field studies.
