<p>Supplementary material</p><p>(Supplementary) Figure 1. Areas identified as potentially suitable to support wild dog dispersal. The effect of wild dog group size on model output was investigated. Using the same set of predictor variables, the model was run using occurrence records where wild dog group size numbered a) ≤ 2 (n = 119), b) ≤ 4 (n = 290), c) ≤ 6 (n = 195) and d) ≤ 8 (n = 426). Black = most suitable; white = totally unsuitable. Protected areas which served as potential source populations are shown in green. (Supplementary) Figure 2. The a) current flow model, b) Maxent dispersal model, and c) Maxent pack model reclassified into binary maps. The threshold at which 20% of occurrence records were omitted was identified and used for binary reclassification. The resulting thresholds for the current flow, disperser, and pack model were respectively 0.1564, 0.3432, and 0.1207. Protected areas which served as potential source populations are shown in green.
