ABSTRACT

In captivity, the managers of primate populations have removed individuals from their groups for medical and social reasons, but there has been little documentation regarding the consequences of this extraction on the sociality of the remaining individuals. This study provides information about the social effect of the alpha male removal in a group of olive baboons (Papio anubis) maintained at the Station of Primatology of CNRS (France). Data on social behavior was collected before and after male removal and then compared. Moreover, this social information was used to calculate the individual dominance index and the group dominance ranking. Overall, our results indicate that females seem to respond to male removal showing a more affiliative and tolerant behavior. However, the results also highlight the different coping mechanisms of females with this new social context. Therefore, this information could be useful for managers of primate populations, allowing them to anticipate the response of captive groups when facing certain sociodemographic changes. In this regard, we recommended creating a detailed procedure before the removal of the individuals that considers the characteristics of the individuals.

摘要

在圈养中，灵长类动物种群的管理者出于医疗和社会原因将个体从其群体中移除，但关于这种提取对剩余个体的社会性的后果的文献很少。这项研究提供了关于去除一群橄榄狒狒（Papio anubis) 保存在 CNRS（法国）灵长类动物学站。在去除男性之前和之后收集社会行为数据，然后进行比较。此外，该社会信息被用于计算个体优势指数和群体优势排名。总体而言，我们的结果表明，雌性似乎对雄性移除做出反应，表现出更加亲和和宽容的行为。然而，结果也突出了女性在这种新的社会背景下的不同应对机制。因此，这些信息可能对灵长类动物种群的管理者有用，使他们能够预测圈养群体在面临某些社会人口变化时的反应。在这方面，我们建议在考虑个人特征的情况下，在移除个人之前制定详细的程序。
