Data & code for - Predation selection impacts social information use in guppies (Poecilia reticulata)

Here we use artificial selection lines of Trinidadian guppies (Poecilia reticulata) that had been selected for predation survival for three generations (and control lines that were visually and olfactory exposed to predation but in a secured enclosure) to test how predation selects for social information use. Individuals observed a demonstrator on a screen solving a colour association task, correctly or incorrectly, before attempting the task themselves. We show that individuals from both treatments learned the task, but only animals from the control lines relied on the use of social information during the process, while animals from the predation lines prioritized private information.For details on the data files, please refer to the README file included in this archive.

本数据集采用经过三代捕食存活选育的特立尼达孔雀鱼（Poecilia reticulata）人工选育品系，同时设置对照组品系——该组个体可通过视觉与嗅觉感知捕食者，但处于封闭安全围栏内——以此探究捕食压力对社会性信息利用策略的选择作用。实验流程为：受试个体先在显示屏上观察示范者完成一项颜色关联任务，示范者的任务结果或对或错，随后受试个体自行尝试该任务。研究结果表明，两组处理组的个体均成功习得该任务，但仅对照组品系个体在学习过程中依赖社会性信息，而捕食选择品系个体则优先使用私有信息。有关本数据集文件的详细说明，请参阅本归档包内附带的README文件。
