  1. Data for pre-predation and post-predation are separated by/for applicable metrics. Days with detections indicates the number of unique days the ID code was detected in the array. Timespan detected indicates the timespan the ID code could have been detected in the array based on the difference between the release date and time and the timestamp of the last detection of the pre-predated ID and the difference between the first and last detection timestamp of the post-predated ID. Total timespan detected is the difference between the date and time of the last detection of the post-predation ID and the release date and time
