Data accompanying "Latitudinal variation in the timing of nest predator activity is habitat specific"

The aim of this work was to test the hypothesis that that activity patterns of bird nest predators transitions from nocturnal to diurnal with increasing latitude. We collected the identity of nest predators from published data of camera surveillance at nests on the global scale. We performed ordinal and logistic regressions to study the correlation between predator activity patterns and the latitude. This is the final data set, along with the R-scripts we used to perform the statistical analyses. Please read the "readme.txt" file before running the scripts. A list of references from which predation and activity pattern data was extracted is also provided.本研究旨在验证如下假说：鸟类巢捕食者的活动模式会随纬度升高从夜行性转向昼行性。我们从全球尺度的巢相机监测已发表数据中收集了巢捕食者的身份信息。我们采用有序回归与逻辑回归分析，探究捕食者活动模式与纬度之间的相关性。本数据集与我们用于开展统计分析的R脚本一并提供。运行脚本前请阅读readme.txt文件。此外还附带了提取捕食与活动模式数据的参考文献列表。
