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.

如今，在非洲和亚洲都发现了旧世界猴子，并具有各种身体和行为适应，使它们能够在一系列栖息地中生存并共存。非洲的化石过去表现出类似的旧世界猴子多样性和共存的模式，尽管并非所有这些化石物种都幸存下来。这个博士学位论文项目将研究旧世界猴子社区如何响应当地的环境条件，以及为什么这些社区中的某些物种比其他物种更成功。与饮食适应性相关的牙科特征将用于重建生活和化石旧世界猴子的生态，并比较不同时间和地理环境的社区。这将提供长期的背景，以了解旧世界猴子社区的当今多样性，并预测这些社区对正在进行和未来环境变化的潜在反应。该项目将直接吸引本科生参与研究，包括来自STEM中传统代表性不足的群体的学生。照片和测量数据将在线免费提供给其他研究人员；它们还将用于创建与当地学校和博物馆共享的书面文章和教育材料，并在在线发布在Askanananthropostors.asu.asu.edu网站上。该项目使用了当今非洲和亚洲的旧世界猴子社区以及非洲化石记录中的广泛的时间和地理样本，以系统地测试将物种多样性，适应和灭绝与当地环境现象联系起来的假设。牙科度量数据将用于创建旧世界猴子生态形态利基市场的多元模型，研究人员将通过该模型计算和比较社区的小众销量，位置和重叠。然后，将使用模型选择来评估气候因素，栖息地结构，哺乳动物竞争以及领先社区具有相似或不同生态形态壁球的相对影响。由于旧世界的猴子在化石和当今社区中的代表性很好，因此它们为了解过去，现在和未来的多样性和灭绝模式提供了理想的模型。该奖项反映了NSF的法定任务，并认为通过使用该基金会的智力和更广泛的影响来评估Criteria的智力和更广泛的影响。
