Data for Pace of life, predators and parasites: Stephenson et al. Biology Letters

These data are from guppies, Poecilia reticulata, from several sample sites across Trinidad. For each fish, we recorded the sex, weight, condition (using the scaled mass index), and the presence and number of Gyrodactylus spp. parasites infecting the fish. We provide the drainage, river, course and site, as well as the nested terms where appropriate, where each fish was collected.

本数据集的样本取自特立尼达岛多个采样点的孔雀鱼（guppies，*Poecilia reticulata*）。针对每条样本个体，我们记录了其性别、体重、健康状况（采用标准化体重指数（scaled mass index）进行评估），以及感染的三代虫属（Gyrodactylus spp.）寄生虫的感染状态与寄生数量。此外，我们还提供了每条样本鱼的采集位点所属的流域、河流、河道段与具体采样点信息，并在适宜场景下补充了对应的嵌套层级分类项。
