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.
由于非法贩运等人类活动，灵长类种群正面临威胁，这需要诸如重新引入计划等保护措施。然而，这些举措往往会遇到挑战，比如与移动和觅食相关的个体行为方面的问题。有人认为有经验的同种个体的存在有助于提高这些计划的成功率。本研究聚焦于绒毛猴，考察有经验的同种个体的存在如何影响重新引入个体的表现。采用焦点动物取样法收集了三组重新引入的绒毛猴在接近度、饮食组成、活动范围和垂直层次利用方面的数据。在个体放归后的前2个月和6个月对数据进行了分析。结果表明，有经验的同种个体的参与加快了适应过程，尤其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有过野外经验的个体纳入重新引入群体以提高成功可能性的重要性。此外，该研究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。这项研究为灵长类保护提供了有价值的见解，强调了在有效重新引入工作的规划和实施中考虑有经验个体的存在以及可能的社会学习过程的重要性。
