The distribution of species across the globe is influenced by several factors including climate, habitat, evolutionary history, and interactions with other organisms. Research on species distribution has primarily focused on modern climate variation and species distributions. In this project, a novel combination of paleontological and modern ecological data will be used to examine how past climate patterns and competition among mammals have contributed to current primate biodiversity. As habitat loss and fragmentation are occurring worldwide, research investigating the factors determining primate biodiversity has implications for conservation management and maintaining the integrity of tropical forest ecosystems. Obtaining a better understanding of how primate distributions change through time and in response to changing environments will inform models for predicting shifts in primate ranges and community structure for future climates and habitat changes. The project will include the development of a database and web-based science education resources, and training of students from traditionally under-represented populations in the STEM fields. Students will gain important skills in data management and analyses that can subsequently be used in a wide variety of future career paths. The project seeks to examine primate community phylogenetic and trait structure across space and through time with abiotic and biotic factors suggested to cause the changing distributions and adaptations of primate species. The project is unique because fossil species locations and traits will be integrated with extant community data for macro-ecological and evolutionary analyses. Some of the questions addressed will be: Do communities found in similar environments, but on different continents, converge on the same structures? Do climate patterns from the Miocene through the present influence primate community structure? Do the presence and diversity of non-primate mammals that are potential primate competitors impact primate community structure? Are trait and phylogenetic structures of fossil primate communities predicted by climatic characteristics? The research proposed in this project will address topics that are central to understanding the modern and past distribution and coexistence of primates and other mammals. Using a community-level approach is essential for understanding how species interact to impact the evolution of each other's behavior, ecology, and morphology. Obtaining a better understanding of how primate communities change through time and in response to changing environments will inform models for predicting future shifts in primate distributions and community structure related to climate and habitat change.

全球物种的分布受到多种因素的影响，包括气候、栖息地、进化历史以及与其他生物的相互作用。物种分布的研究主要集中在现代气候变化和物种分布。在该项目中，古生物学和现代生态数据的新颖组合将用于研究过去的气候模式和哺乳动物之间的竞争如何对当前灵长类动物的生物多样性做出贡献。随着世界范围内栖息地丧失和破碎化的发生，对决定灵长类动物生物多样性的因素进行研究对保护管理和维持热带森林生态系统的完整性具有重要意义。更好地了解灵长类动物分布如何随时间变化以及对不断变化的环境做出反应，将为预测灵长类动物分布范围和群落结构因未来气候和栖息地变化而变化的模型提供信息。该项目将包括开发数据库和基于网络的科学教育资源，以及对 STEM 领域传统上代表性不足的群体的学生进行培训。学生将获得数据管理和分析方面的重要技能，这些技能随后可用于未来的各种职业道路。 该项目旨在研究跨空间和跨时间的灵长类群落系统发育和性状结构，以及导致灵长类物种分布和适应变化的非生物和生物因素。该项目是独一无二的，因为化石物种的位置和特征将与现有的群落数据相结合，以进行宏观生态和进化分析。解决的一些问题是：在相似的环境中但在不同的大陆上发现的社区是否会聚集在相同的结构上？中新世至今的气候模式是否影响灵长类群落结构？作为灵长类潜在竞争者的非灵长类哺乳动物的存在和多样性是否会影响灵长类群落结构？化石灵长类群落的性状和系统发育结构是否可以通过气候特征预测？该项目提出的研究将解决对于了解灵长类动物和其他哺乳动物的现代和过去分布和共存至关重要的主题。使用群落层面的方法对于了解物种如何相互作用以影响彼此的行为、生态和形态的进化至关重要。更好地了解灵长类动物群落如何随时间变化以及对不断变化的环境做出反应，将为预测灵长类动物分布以及与气候和栖息地变化相关的群落结构未来变化的模型提供信息。
