来自相机陷阱的数据记录了一天中拍摄照片的时间，这些数据被广泛用于研究拍摄物种的日常活动模式。例如，比较一个物种的交配和雌性之间或捕食者和被捕食物种之间的活动模式通常是有意义的。在本文中，我们建议可以通过衡量两个活动模式的重叠程度来量化两个活动模式之间的相似性。描述了几种估计这种重叠度量的方法，并在模拟研究中研究了它们对活动数据的比较性能。通过使用苏门答腊岛Kerinci Seblat国家公园相机陷阱的数据比较三种同域猫科动物的活动模式，说明了这些方法。
Data from camera traps that record the time of day at which photographs are taken are used widely to study daily activity patterns of photographed species. It is often of interest to compare activity patterns, for example, between mates and females of a species or between a predator and a prey species. In this article we propose that the similarity between two activity patterns may be quantified by a measure of the extent to which the patterns overlap. Several methods of estimating this overlap measure are described and their comparative performance for activity data is investigated in a simulation study. The methods are illustrated by comparing activity patterns of three sympatric felid species using data from camera traps in Kerinci Seblat National Park, Sumatra.
