Abbreviations: Avg. rank, average model ranking from 10 000 bootstrap iterations; K, number of parameters in the transformation of continuous surfaces or number of land cover classes in categorical surfaces; TPI, topographic position index; Ω̄, Akaike weight representing the probability that a model is the best in the model set, averaged over 10 000 bootstrap iterations; π̂, proportion of 10 000 bootstrap iterations that a model was the top model. Only surfaces that were selected as the top model more frequently than distance alone were used to develop composite models.
