几个物种的圈养动物改变其行为模式和激素谱响应物理（例如，笼子的大小和温度）和社会（例如，群体大小和社会隔离）修改他们的环境。为了评估圈养环境变化的影响，在工作日（非安静）和周末（安静）的两个月内，记录了五个家庭组的普通绒猴，Callithrix jacchus的亲和（接触/接近和allogrooming）和个人（方法，离开，气味标记，运动，和automoroming）的行为。此外，还收集了其中四组的粪便样本，以测量两种条件下的皮质醇水平。繁殖对及其后代的行为模式和激素分布进行了修改，在实验条件下使用不同的管理程序。我们发现，动物在周末花更多的时间在亲和互动上，而在工作日，它们表现出更多的个体行为。此外，繁殖对及其后代的皮质醇水平在工作日更高，这表明生活在圈养环境中的普通绒猴通过改变行为和激素模式对环境改变做出反应。
Captive animals of several species change their behavioral pattern and hormonal profile in response to physical (for example, cage size and temperature) and social (for example, group size and social isolation) modification of their environment. To evaluate the effect of environmental change in captivity, the affiliative (contact/proximity and allogrooming) and individual (approach, leaving, scent mark, locomotion, and autogrooming) behavior of five family groups of common marmosets, Callithrix jacchus, were recorded on weekdays (non-quiet) and at the weekend (quiet) for two months. In addition, fecal samples were collected for four of these groups to measure their cortisol levels under both conditions. The behavioral pattern and hormonal profile of breeding pairs and their offspring were modified by different management routines used in the experimental conditions. We found that the animals spent more time in affiliative interactions at the weekend, whereas on weekdays, they showed more individual behaviors. Moreover, cortisol levels of breeding pairs and their offspring were higher on weekdays, suggesting that common marmosets living in captivity react to environmental modification by changing their behavioral and hormonal pattern.
