Behavioral and physiological plasticity allows organisms to rapidly adapt to shifting environmental conditions without genetic change. In primates, which are relatively long-lived, the evolutionary ability to inhabit new habitats and survive periods of rapid environmental change likely depended on these types of plasticity. Information about primates’ behavioral and physiological plasticity is currently needed to understand the nature and limits of their responses and the adaptations primates may be able to use to respond to the rapid environmental change they are currently experiencing. This doctoral research project investigates how adaptation to a variable high-elevation environment is shaped by an endangered ape’s plasticity. In addition to its significant conservation implications, this project makes important education, training, and capacity building contributions both domestically and internationally. This research project explores the behavioral and physiological plasticity of an endangered ape species. To date, we do not know how environmental stressors vary across this species' many habitats, and we lack information about the types of behavioral and physiological responses these apes employ to respond to these stressors. The methods used in this study include a novel environmental protocol, non-invasive behavioral observations, and biological sample collection. These data can reveal the environmental challenges this species faces, and the behavioral and physiological responses it elicits. This study informs us about the ability that this ape species has to respond to environmental change, and the evolutionary role that environmental stressors play on primates and other organisms with slow life histories.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.

行为和生理可塑性使生物体能够在不发生基因变化的情况下快速适应不断变化的环境条件，而灵长类动物的寿命相对较长，其适应新栖息地和在快速环境变化时期生存的进化能力可能取决于这些类型的可塑性信息。目前需要了解灵长类动物的行为和生理可塑性，以了解其反应的性质和限制，以及灵长类动物可能能够用来应对它们目前正在经历的快速环境变化的适应性。高海拔环境是由濒临灭绝的猿类的可塑性决定的，除了具有重大的保护意义外，该项目还在国内和国际上做出了重要的教育、培训和能力建设贡献。迄今为止，我们不知道该物种的许多栖息地的环境压力因素如何变化，并且我们缺乏有关这些猿类应对这些压力因素的类型和生理反应的行为信息。本研究中使用的方法包括一种新颖的方法。环境的这些数据可以揭示该物种面临的环境挑战，以及它引起的行为和生理反应，让我们了解该猿物种应对环境变化的能力。 ，以及环境压力源对灵长类动物和其他生命史缓慢的生物体所起的进化作用。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
