项目摘要

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. Angolan black-and-white colobus monkeys (Colobus angolensis ruwenzorii) form large aggregations made up of individuals and subgroups that frequently fission and range apart before coming together again. Angolan colobus will be used to understand group-level movements and this project will determine whether there is structure to this subgrouping, what factors influence fission and fusion events, the ways that subgroups synchronize their movements, and the spatial organization of subgroups. Vervet monkeys (Chlorocebus pygerythrus) form smaller, cohesive, matrilineal groups and provide the perfect system to examine individual-level movements. This project will examine why individuals choose to join group progressions and how they decide which resources to visit based on specific food attributes and the presence or absence of competitors and allies. Foraging experiments can be done with single vervet monkeys and the same individuals as part of a social group, thus movement decisions can be compared in solitary and social contexts for the same individuals. This allows an analyses of how individual decision-making is altered by the presence of others. This project will aid in clarifying how gregarious animals balance the costs and benefits of living with others and the underlying drivers of animal movement patterns at multiple scales.
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。安哥拉黑白结核猴(Colobus Angolensis Ruwenzorii)由个体和亚群组成的大型聚集体,它们经常分裂和分散,然后再次聚集在一起。安哥拉人的结节将被用来理解群体一级的运动,这个项目将确定这个亚群是否有结构,什么因素影响裂变和聚变事件,亚群同步其运动的方式,以及亚群的空间组织。马尾猴(Chlorocbus Pygerythus)形成更小、更有凝聚力的母系群体,并提供完美的系统来检查个体水平的运动。这个项目将研究为什么个人选择加入团体进步,以及他们如何根据特定的食物属性以及竞争对手和盟友的存在或不存在来决定访问哪些资源。觅食实验可以用单一的体猴和相同的个体作为社会群体的一部分,因此可以比较相同个体在孤独和社交环境下的运动决策。这使得对个人决策如何因他人的存在而改变的分析成为可能。这个项目将有助于阐明群居动物如何平衡与其他动物一起生活的成本和收益,以及动物在不同尺度上运动模式的潜在驱动因素。
