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.

这项研究将整合两个灵长类物种不同年龄段的食物物理特性、个体在打开和吃食物时使用的行为以及下颌肌肉力学的研究，揭示在重要的发育里程碑期间，解剖学和行为是如何相互作用影响摄食性能的。这项研究的结果将有助于我们更好地理解在发育过程中如何选择特定的摄食行为策略，形成成人的摄食行为以及相关的肌肉骨骼解剖学。此外，这些发现可能会为理解和重建灵长类化石和古人类行为的模型提供参考。该项目将促进国际研究合作，为一名女性博士后科学家和多名本科生和研究生提供STEM培训机会，并支持四名职业早期女性科学家。结果将被用来发展K-12学生的灵长类行为和解剖练习，并为K-12教师提供培训，以便有效地教授这些练习。此外，这项研究的结果将与外地地点的保护和社区外展工作有关。这项研究将整合不同的数据集来检验灵长类摄食系统的形式-功能假说。这项拟议的研究的中心目标是检查未成熟的灵长类在个体发育过程中如何应对进食能力的限制，如最大下巴张口和咬合力。为了解决这一目标，这项研究将比较两个相关灵长类物种的摄食系统发展，一个利用坚硬、坚韧和相对较大的食物，另一个吃较小、机械挑战较小的食物。具体地说，这个项目将：1)整合实验和生态学数据，研究近缘灵长类物种食物特性、摄食行为和摄食系统功能和形态的发育变化；2)建立未成熟灵长类动物饮食和形态之间的功能关系，以研究发育期间对特定摄食行为的选择如何与成体形态相关，并在整个个体发育过程中保持摄食性能；以及3)将摄食系统骨骼形态数据与摄食系统性能关键决定因素的数据相结合，包括食物特性、咬合力和张口。这些结果有助于我们对现存灵长类生态形态的理解，也为化石分类中饮食驱动的形态的出现和分化提供了一个完整的模型。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
