Abstract

Primate populations are under threat due to human activities, like illegal trafficking, requiring conservation efforts such as reintroduction programs. However, these initiatives often encounter challenges, such as aspects of individual behavior related to movement and foraging. The presence of experienced conspecifics has been suggested to improve the success of these programs. This study focuses on woolly monkeys and examines how the presence of experienced conspecifics influences the performance of reintroduced individuals. Focal animal sampling was used to collect data on proximity, diet composition, home range, and use of vertical strata of three groups of reintroduced woolly monkeys. Data was analyzed for the first 2 and 6 months after release of individuals. The results reveal that the involvement of experienced conspecifics speeds up the process of adaptation, particularly in terms of diet diversity and spatial utilization; however, differences in individual responses were also prevalent. Our findings highlight the importance of incorporating individuals with prior wild experience into reintroduction groups for improving the likelihood of success. Additionally, the study underscores the role of social learning in captive management practices, aiding in post-release behavioral adaptation and survival. This research offers valuable insights for primate conservation, emphasizing the significance of considering the presence of experienced individuals and possible social learning processes in the planning and execution of effective reintroduction efforts.

在哥伦比亚,有经验的个体会增强重新引入的毛猴的行为和生存能力。
由于非法贩运等人类活动,灵长类动物的数量正受到威胁,这就需要开展重新引入计划等保护工作。然而,这些计划经常会遇到一些挑战,例如与运动和觅食有关的个体行为。有研究表明,有经验的同类存在可以提高这些计划的成功率。本研究以毛猴为研究对象,探讨有经验的同种动物的存在如何影响重新引入个体的表现。研究采用重点动物取样法收集了三组重新引入的毛猴的亲缘关系、食物组成、家园范围和垂直层的使用情况等数据。对释放后头 2 个月和 6 个月的数据进行了分析。结果表明,有经验的同类的参与加快了适应过程,特别是在饮食多样性和空间利用方面;然而,个体反应的差异也很普遍。我们的研究结果凸显了将具有野外经验的个体纳入重新引入群体对提高成功可能性的重要性。此外,这项研究还强调了社会学习在圈养管理实践中的作用,有助于放归后的行为适应和生存。这项研究为灵长类动物保护提供了宝贵的见解,强调了在规划和执行有效的再引入工作时考虑有经验个体的存在和可能的社会学习过程的重要性。

期刊介绍: Primates is an international journal of primatology whose aim is to provide a forum for the elucidation of all aspects of primates. The oldest primatological journal, Primates publishes original papers that advance the scientific study of primates, and its scope embraces work in diverse fields covering biological bases of behavior, socio-ecology, learning and cognition, social processes, systematics, evolution, and medicine. Contributions relevant to conservation of natural populations and welfare of captive primates are welcome. Studies focusing on nonprimate species may be considered if their relevance to primatology is clear. Original Articles as well as Review Articles, News and Perspectives, and Book Reviews are included. All manuscripts received are initially screened for suitability by members of the Editorial Board, taking into account style and ethical issues, leading to a swift decision about whether to send the manuscript for external review.
