Understanding the drivers of individual and group-level movements in gregarious species

动物群体在景观中的错综复杂的移动以及群体内个体的移动还没有被很好地理解。表面上看，这是个人为了最大限度地满足自己当前的需求而相对他人进行策略调整的结果，但还需要进一步的研究来澄清不同类别个人的策略。与同一物种的个体交往既有成本，也有好处；通过控制群体规模、个体间的接近程度、性别比例和群体运动方向，可以减轻成本，增加好处。然而，根据性别和生命阶段的不同，动物控制这些变量的能力也不同。在选择它们各自的移动路径时，动物还必须考虑它们的资源需求、食物地点的多种不同方式以及竞争对手和盟友的位置。该项目旨在利用乌干达Nabugabo湖两种群居的非人类灵长类动物，了解群体水平和个人水平运动背后的重要因素。安哥拉黑白瘤猴(

The intricate movements of animal groups across landscapes and of individuals within groups are not well understood. Ostensibly these are the outcome of individuals’ manoeuvering relative to others to best meet their current needs but further study is needed to clarify the strategies of different classes of individuals. There are both costs and benefits of associating with individuals of the same species; and the costs may be mitigated and the benefits increased by controlling group size, inter-individual proximity, sex-ratios, and group movement direction. However, depending on their sex and life stage, animals vary in their abilities to control these variables. When choosing their individual movement paths animals must also consider their resource needs, the multiple ways that food sites vary, and the locations of competitors and allies. This project aims to understand the important factors underlying group-level and individual-level movements using two species of group-living nonhuman primates at Lake Nabugabo, Uganda.
