Ensuring welfare in captive wild animal populations is important not only for ethical and legal reasons, but also to maintain healthy individuals and populations. An increased level of social behaviors such as aggression can reduce welfare by causing physical damage and chronic stress to animals. Recently, cortisol in hair has been advanced as a non-invasive indicator to quantify long-lasting stress in many species. The sensitivity of social behavior and hair cortisol concentration was evaluated in several groups of dorcas gazelles (Gazella dorcas). Four different groups of gazelles from three different zoos were observed and the expression of intra-specific affiliative and negative social behaviors was assessed across the different groups. Hair samples were taken from sub-groups of animals and analyzed for cortisol concentrations. Significant differences between groups of dorcas gazelles were found in frequency of negative social behavior and hair cortisol concentration. Despite the low sample size, these two parameters had a positive Spearman correlation coefficient (r = +0.80, P = 0.20). These results suggest that hair cortisol levels are sensitive to differences in the social structure of dorcas gazelles. Zoo Biol. 35:467-473, 2016. © 2016 Wiley Periodicals, Inc.
确保圈养野生动物种群的福利不仅出于伦理和法律原因很重要，而且对于维持个体和种群的健康也很重要。诸如攻击行为等社会行为水平的提高会对动物造成身体伤害和慢性应激，从而降低福利。最近，毛发中的皮质醇已被视为一种非侵入性指标，用于量化许多物种的长期应激。对几组多卡瞪羚（Gazella dorcas）的社会行为和毛发皮质醇浓度的敏感性进行了评估。观察了来自三个不同动物园的四组不同的瞪羚，并评估了不同组间种内亲和性和负面社会行为的表现。从动物亚组采集毛发样本并分析皮质醇浓度。在多卡瞪羚组之间，负面社会行为的频率和毛发皮质醇浓度存在显著差异。尽管样本量较小，但这两个参数具有正的斯皮尔曼相关系数（r = +0.80，P = 0.20）。这些结果表明，毛发皮质醇水平对多卡瞪羚社会结构的差异敏感。《动物园生物学》。2016年第35卷：467 - 473页。© 2016威利期刊公司。
