In this project, I will use automated tracking technology and machine learning to test how individual investments and decision-making are influenced by the social environment. To achieve this, I will develop a method for automated detection of decision-making in a wild population of squirrels, and combine this with technological methods that allow me to construct social networks (quantifying social relationships) and spatial networks (documenting home ranges). Study system I will conduct my project on the long-term field site of the eastern grey squirrels at the University of Exeter campus (established in 2005 by my proposed primary supervisor, Dr Lisa Leaver). Eastern grey squirrels are scatter-cachers relying on cached food for considerable portions of the year[2]. Thus, caching decisions are of significant importance for individual survival. Squirrels are often described as asocial but both sexes nest communally and females show natal philopatry and have overlapping home ranges[12]. Individuals in the campus population are habituated to humans and routinely trapped and marked with PIT tags, such that individuals are monitored across multiple years. This trapping protocol will allow me to fit GPS collars and accelerometers with relative ease.

在这个项目中，我将使用自动跟踪技术和机器学习来测试个人投资和决策如何受到社会环境的影响。为了实现这一目标，我将开发一种在野生松鼠种群中自动检测决策的方法，并将其与允许我构建社交网络（量化社会关系）和空间网络（记录活动范围）的技术方法相结合。研究系统 我将在埃克塞特大学校园的东部灰松鼠长期野外考察场地（由我提议的主要导师 Lisa Leaver 博士于 2005 年建立）开展我的项目。东部灰松鼠是分散储藏者，一年中相当长的时间依赖储藏的食物[2]。因此，缓存决策对于个体生存至关重要。松鼠通常被描述为不合群，但两性都共同筑巢，雌性松鼠表现出与生俱来的亲性，并且有重叠的居住范围[12]。校园中的个体已经习惯了人类，并且经常被困住并贴上 PIT 标签，这样个体就会受到多年的监控。这种捕获协议将使我能够相对轻松地安装 GPS 项圈和加速计。
