Doctoral Dissertation Improvement: Dynamic Habitat Partitioning among Savannah Baboon Social Groups - the Role of Group-level Social Dominance Hierarchies

大多数灵长类生活在相对稳定的社会群体中，对许多物种来说，这些群体占据了部分重叠的家园。 这种非排他性提出了关于群体何时以及如何在时间上划分景观的基本问题。 本研究的中心假设是，群体层次的社会支配等级制度的功能，以解决群体间的资源竞争，从而propioneering影响社会群体之间的资源分配，并最终影响群体之间的差异，在群体成员的平均个人健身。 调查组一级的主导地位的影响，随着时间的推移，空间利用的动态是一个很好的特点，人口的大草原狒狒（Papio cynocephalus）在非洲东部的安博塞利盆地这项研究的重点。 除了利用长期的生态，生活史和行为数据，研究人员还将使用现代地理信息系统（GIS）工具收集新的数据，以（1）自动记录预定的同步时间表上的许多群体的位置，（2）在研究系统中描绘资源和栖息地。 这些方法将首次允许详细分析这一种群内多个群体的相互关联的移动以及它们争夺的生态资源之间的时空关系。 研究结果将提供必要的数据，以检查集群级的问题，如如何组级的优势模式影响在哪里和何时移动的群体相对于彼此，什么样的作用，这些层次结构在调解时，群体有机会获得有限的资源，以及空间环境对资源的选择和开发的影响。 由于狒狒被认为是人类有价值的类似物，这些发现将对现代灵长类动物和人类祖先的空间生态学具有重要意义。 将开发一个专门的网站组件，通过互动式制图应用程序展示研究结果和影响，说明动态空间使用和移动模式。

Most primates live in relatively stable social groups, and for many species these groups occupy partially overlapping homeranges. This non-exclusivity raises fundamental questions about when and how groups temporally partition the landscape. The central hypothesis of this study is that group-level social dominance hierarchies function to resolve intergroup resource competition, thus proximately affecting the allocation of resources among social groups and ultimately affecting differences between groups in the average individual fitness of group members. Investigating the influence of group-level dominance on the dynamics of space use over time is the focus of this research on a well-characterized population of savannah baboons (Papio cynocephalus) in the Amboseli basin of east Africa. In addition to utilizing long-term ecological, life history, and behavioral data available through the Amboseli Baboon Research Project, researchers will collect novel data using modern geographic information system (GIS) tools to (1) automatically record the locations of numerous groups on a pre-determined, synchronous schedule and (2) delineate resources and habitats within the study system. These approaches will, for the first time, permit detailed analyses of both the interrelated movements of multiple groups within this population and the temporal and spatial relationship among the ecological resources for which they compete. Results will thereby provide data essential to examining landscape-level questions such as how group-level dominance patterns affect where and when groups move in relation to one another, what role these hierarchies have in mediating when groups have access to limited resources, and the influence of spatial context on resource selection and exploitation. Because baboons are considered valuable analogs to hominins, findings will have significance relevant to the spatial ecology of both modern primates and human ancestors. A dedicated website component will be developed to present the research findings and implications through interactive mapping applications that illustrate dynamic space-use and movement patterns.
