The covariate roads described road density (km roads/km²) and the covariate droads described distance from roads or other anthropogenic features. Sample-size adjusted Akaike Information Criteria (AIC_c), difference in AIC_c between most supported and given model (ΔAIC_c), Akaike weight (w_i), the number of parameters (K), and Deviance are shown.
