这项研究调查了幼年黑猩猩（黑猩猩）对一种已知压力源（麻醉）和三种不寻常事件的尿皮质醇应激反应，这些事件被认为会导致皮质醇增加（由于飓风、浓缩运动和群体组成的变化而被限制在半个围栏内数天）。尽管在圈养动物中已经记录了皮质醇对各种实验室经历的应激反应，但尚不清楚其他类型的非典型事件是否会带来压力，包括那些不一定是负面的事件。对 20 只清醒、不受约束的黑猩猩收集的 519 份尿液样本进行了皮质醇测量；将个体与他们自己的基线值进行比较。麻醉应激导致尿皮质醇浓度显着增加，但其他三种潜在应激源导致尿皮质醇浓度没有显着变化。尿皮质醇对这些事件缺乏反应可能表明这些事件实际上并没有给黑猩猩带来压力，但可能是由于测量皮质醇排泄作为综合分泌指标的时间分辨率有限，或者是由于竞争行为率的变化造成的。
This study investigated the urinary cortisol stress response to one known stressor (anaesthesia) and three unusual events hypothesized to result in increases in cortisol (confinement to one half of an enclosure for several days due to a hurricane, an enrichment exercise, and a change in group composition) in young chimpanzees (Pan troglodytes). Although a cortisol stress response to a variety of laboratory experiences has been documented in captive animals, it is unclear whether other types of atypical events are stressful, including those that are not necessarily negative. Cortisol was measured in 519 urine samples collected from 20 awake, unrestrained chimpanzees; individuals were compared against their own baseline values. A significant increase in urinary cortisol concentration was found as a result of the stress of anaesthesia, but no significant change in urinary cortisol resulted from the three other potential stressors. A lack of a urinary cortisol response to these events may indicate that the events were not actually stressful for the chimpanzees, but may have resulted from the limited temporal resolution of measuring cortisol excretion as an indicator of integrated secretion, or from changes in rates of agonistic behaviors.
