Table 2 Case Study 1: Summary movement and activity space metrics calculated for four species at multiple sites within Australia

From: A standardised framework for analysing animal detections from automated tracking arrays

  1. Northern and southern release sites for each species are represented in Fig. 2. Mean ± SD of step dispersal metrics and KUD estimates across individuals tagged at each release site. The area of site arrays was estimated by calculating the area encompassing the listening ranges of all receivers within each regional installation. Area of site array was incorporated within each ANOVA comparison presented in Fig. 2
