项目摘要

Old World monkeys are found across Africa and Asia today with various physical and behavioral adaptations that allow them to survive and coexist in a range of habitats. Fossils from Africa show a similar pattern of Old World monkey diversity and coexistence in the past, although not all of these fossil species survived to the present. This doctoral dissertation project will examine how Old World monkey communities change in response to local environmental conditions and why some species within these communities are more successful than others. Dental features associated with dietary adaptations will be used to reconstruct the ecologies of living and fossil Old World monkeys and to compare across communities from different temporal and geographic settings. This will provide long-term context for understanding the present-day diversity of Old World monkey communities and for predicting potential responses of these communities to ongoing and future environmental change. This project will directly engage undergraduates in research, including students from traditionally underrepresented groups in STEM. Photographs and measurement data will be made freely available online to other researchers; they will also be used to create written articles and educational materials shared with local schools and museums, and posted online for the general public on the AskAnAnthropologist.asu.edu website.A range of climatic, ecological, biogeographical, and phylogenetic hypotheses have been proposed to explain how and why present-day primate communities contain certain combinations of species and adaptations. This project uses a broad temporal and geographic sample of Old World monkey communities in Africa and Asia today and in the African fossil record to systematically test hypotheses linking species diversity, adaptation, and extinction with local environmental phenomena. Dental metric data will be used to create a multivariate model of the Old World monkey ecomorphological niche, from which the researchers will calculate and compare community niche volumes, positions, and overlap. Model selection will then be used to evaluate the relative influence of climate factors, habitat structure, mammalian competition, and dispersal barriers in leading communities to have similar or distinct ecomorphological niches. As Old World monkeys are well-represented in the fossil and present-day communities, they provide an ideal model for understanding complex patterns of diversity and extinction in the past, present, and future.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.

今天，在非洲和亚洲发现了旧大陆猴子，它们具有各种身体和行为适应能力，使它们能够在一系列栖息地中生存和共存。来自非洲的化石显示了旧大陆猴子多样性和共存的类似模式，尽管并非所有这些化石物种都存活到了现在。这个博士论文项目将研究旧世界猴子群落如何根据当地的环境条件变化，以及为什么这些群落中的一些物种比其他物种更成功。与饮食适应相关的牙齿特征将用于重建活的和化石的旧世界猴的生态，并比较来自不同时间和地理环境的社区。这将提供长期的背景下，了解当今的多样性，旧世界的猴子社区，并预测这些社区的潜在反应，以持续和未来的环境变化。该项目将直接让本科生参与研究，包括来自传统上代表性不足的STEM群体的学生。照片和测量数据将在网上免费提供给其他研究人员;它们还将用于撰写与当地学校和博物馆共享的书面文章和教育材料，并在www.example.com网站上发布给公众AskAnAnthropologist.asu.edu。和系统发育假说已被提出来解释如何以及为什么今天的灵长类动物社区包含某些物种和适应的组合。该项目使用了广泛的时间和地理样本的旧世界猴子社区在非洲和亚洲今天和非洲的化石记录，系统地测试假设连接物种多样性，适应和灭绝与当地的环境现象。牙齿测量数据将用于创建旧世界猴生态形态生态位的多变量模型，研究人员将从中计算和比较群落生态位体积，位置和重叠。模型选择，然后将被用来评估气候因素，栖息地结构，哺乳动物的竞争，并在领先的社区扩散障碍的相对影响，有相似或不同的生态形态的小生境。由于旧大陆的猴子在化石和现今的群落中都有很好的代表性，它们为理解过去、现在和未来复杂的多样性和灭绝模式提供了理想的模型。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
