Rubenstein-Sundaresan Doctoral Dissertation Improvement GrantIndividual Behavior and Female Associations in Fission-Fusion EquidSocietiesAnimal societies result from the sum of all relationships that develop amongindividuals within populations. Many studies have demonstrated howenvironmental circumstances, both ecological and social, influence the benefitsand costs associated with the various behavioral options available toindividuals and thus how they these factors structure animal societies. Yet inspecies where potential relationships are many and those that form are fluid,the link between environmental features and the relationships that develop arepoorly understood. This project explores how ecological features, such as thedistribution of food, water and predator-free sites, together with thedemographic and social features, such as population density and sex ratio,shape individual relationships in the Grevy's zebra and wild ass, twoevolutionarily closely related species exhibiting 'fissioning' and 'fusing'social systems. We have developed a novel model that predicts rules for theformation and breakdown of relationships in such 'open-membership' societiesand forecasts the impact these rules will have on population-wide socialpatterns and processes. Data will be gathered on two endangered equid species,Grevy's zebra and Onagers, from four sites. The four sites provide naturalvariation in the key environmental and social forces and will serve as an idealsystem for testing the predictions of our model. The study will also provideuseful information needed to improve conservation strategies for these speciesby educating students and the local populace and by demonstrating to naturalresource managers how fundamental behavioral research can assist in designingeffective management plans.

Rubenstein-Sundaresan博士论文改进补助金在裂变融合EquidSocietiesAnimal社会的个体行为和女性协会的结果从所有的关系的总和，发展种群内的个体。 许多研究已经证明了生态和社会环境如何影响与个体各种行为选择相关的收益和成本，以及这些因素如何构建动物社会。 然而，在潜在关系众多且形成的关系不稳定的物种中，环境特征与发展的关系之间的联系却知之甚少。该项目探讨了生态特征，如食物，水和无捕食者的地点的分布，以及人口和社会特征，如人口密度和性别比例，如何塑造格雷维斑马和野驴的个体关系，这两个进化上密切相关的物种表现出“裂变”和“融合”的社会系统。我们开发了一个新的模型，预测在这种“开放成员”的社会中关系的形成和破裂的规则，并预测这些规则将对整个人口的社会模式和过程产生的影响。 将从四个地点收集两种濒危马科动物的数据，格雷维斑马和奥纳格斯。这四个地点提供了关键环境和社会力量的自然变化，并将作为测试我们模型预测的理想系统。这项研究还将提供有用的信息，通过教育学生和当地民众，并向自然资源管理人员展示基本行为研究如何帮助设计有效的管理计划，来改善这些物种的保护策略。
