项目摘要

This research will integrate research on the physical properties of food, the behaviors individuals use while opening and eating foods, and jaw muscle mechanics across a range of ages in two primate species, shedding light on how anatomy and behavior interact to influence feeding performance during important developmental milestones. Results of this research will improve our understanding of how selection for particular feeding behavior strategies during development shapes adult feeding behavior and related musculoskeletal anatomy. Additionally, the findings may inform models for understanding and reconstructing behavior from fossil primates and hominins. The project will foster international research collaborations, provide STEM training opportunities for a female postdoctoral scientist and multiple undergraduate and graduate students, and support four early-career female scientists. Results will be used to develop primate behavior and anatomy exercises for K-12 students and provide training for K-12 teachers to effectively deliver those exercises. Furthermore, findings from this research will be relevant to conservation and community outreach efforts at the field sites. This study will integrate diverse datasets to test primate feeding system form-function hypotheses. The central goal of the proposed research is to examine how immature primates cope with feeding performance constraints, such as maximum jaw gape and bite force, during ontogeny. To address this goal, this study will compare feeding system development in two related primate species, one that exploits hard, tough and relatively large foods, and one that eats smaller, less mechanically-challenging foods. Specifically this project will: 1) integrate experimental and ecological data addressing developmental shifts in food properties, feeding behavior, and feeding system function and morphology in closely related primate species; 2) establish functional relationships between diet and morphology in immature primates to examine how selection for particular feeding behaviors during development relates to adult morphologies and maintains feeding performance throughout ontogeny; and 3) integrate data on feeding system skeletal morphology with data on critical determinants of feeding system performance, including food properties, bite force, and gape. These results contribute to our understanding of extant primate ecomorphology and also provide an integrated model for the appearance and differentiation of diet-driven morphology in fossil taxa.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.

这项研究将整合有关食物的物理特性，个人在开放和吃食物时使用的行为，以及在两个灵长类动物中各个年龄段的下颌肌肉力学，阐明了解剖学和行为如何相互作用以影响重要的发展里程碑期间的喂养性能。这项研究的结果将提高我们对开发过程中特定喂养行为策略如何选择成人喂养行为和相关肌肉骨骼解剖结构的理解。此外，这些发现可能会为了解和重建化石灵长类动物和人类的行为的模型提供信息。该项目将促进国际研究合作，为女性博士后科学家以及多个本科生和研究生提供STEM培训机会，并支持四位早期职业女性科学家。结果将用于为K-12学生开发灵长类动物行为和解剖学练习，并为K-12老师提供培训，以有效地进行这些练习。此外，这项研究的发现将与现场现场的保护和社区外展工作有关。这项研究将整合多种数据集，以测试灵长类动物喂养系统形式功能假设。拟议的研究的核心目标是检查未成熟的灵长类动物如何应对个体发育过程中如何应对喂养性能限制，例如最大的颌骨和咬合力。为了解决这一目标，这项研究将比较两个相关的灵长类动物中的喂养系统开发，一种是利用坚硬，坚硬且相对较大的食物，一种食用较小，机械挑战性的食物。具体而言，该项目将：1）整合实验和生态数据，以解决密切相关的灵长类动物中食品特性，喂养行为以及喂养系统功能和形态的发展变化； 2）在未成熟灵长类动物中建立饮食与形态之间的功能关系，以研究在发育过程中对特定喂养行为的选择如何与成人形态有关，并在整个个体发育过程中保持喂养性能； 3）将有关进食系统骨骼形态的数据与有关进食系统性能的关键决定因素（包括食物特性，咬合力和gape）的关键决定因素的数据整合在一起。这些结果有助于我们对现存的灵长类动物生态形态的理解，还为化石分类单元中饮食驱动的形态的外观和区分提供了综合模型。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来支持的。
