Unsuitable environmental conditions are one of the main drivers for evolution as species must adapt, move, or perish. Smaller mammals have avoided the impact of unsuitable environments by becoming nocturnal and moving to refuges. Current unprecedented environmental variations raise the question of how various mammals, including primates, can find suitable habitats. This doctoral dissertation project focuses on understanding how movement and activity are influenced by nocturnal and seasonal changes in environment in a non-human primate, informing broader questions about primate evolution and adaptation. This project provides capacity building, training, and mentorship for undergraduate and graduate students, as well as informing conservation efforts for nocturnal mammals.This project uses an integration of data from direct observations, radio-tracking collars, and temperature and humidity loggers to record environmental and movement information for a small, nocturnal, non-human primate. There are two main objectives: (1) to assess how environmental variables (temperature and humidity) influence this primate’s movement and activity patterns; and (2) to identify areas of the forest which provide a cooler microenvironment and examine if this non-human primate utilizes these areas. This research evaluates the relationship between movement and environment, how sampling effort impacts the results, and builds upon previous home range and habitat suitability models by incorporating a 3D component to represent the vertical movement employed by arboreal primates. This research provides an opportunity to evaluate how the earliest primate ancestors may have mitigated environmental extremes using this non-human primate as a proxy, and how a nocturnal species may behaviorally adapt to environmental change.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

不合适的环境条件是进化的主要驱动因素之一，因为物种必须适应，移动或灭亡。较小的哺乳动物通过成为夜间和避难所来避免了不合适的环境的影响。当前的前所未有的环境变化提出了一个问题，即包括素数在内的各种哺乳动物如何找到合适的栖息地。该博士学位论文项目的重点是了解非人类灵长类动物的夜间和季节性变化的运动和活动如何影响，从而为私人进化和适应性提供了更广泛的问题。该项目为本科生和研究生提供了能力建设，培训和心态，并为夜间哺乳动物的保护工作提供了信息。该项目使用直接观察，无线电跟踪项圈以及温度和湿度日志的数据整合，以记录小型，nocturning nocturn的非人类非人类灵活的环境和运动信息。有两个主要目标：（1）评估环境变量（温度和湿度）如何影响灵长类动物的运动和活动模式； （2）确定森林的区域，如果这种非人类灵长类动物利用这些区域，则可以提供较凉的微环境和考试。这项研究评估了运动与环境之间的关系，采样努力如何影响结果，并通过将3D组件转换以代表由树木隐私进行的垂直运动来基于先前的家庭范围和栖息地适用性模型。这项研究提供了一个机会，可以评估最早的灵长类动物祖先如何使用这种非人类灵长类动物作为代理来减轻环境极端，以及夜间物种在行为上如何在行为上适应环境变化。这项奖项反映了NSF的法定任务，并认为通过基金会的知识优点和广泛的criperia criperia criperia criperia criperia criperia criperia criperia criperia criperia criperia被认为是宝贵的支持。
