Description
Multi‐scale resource selection modeling is used to identify factors that limit species distributions across scales of space and time. This multi‐scale nature of habitat suitability complicates the translation of inferences to single, spatial depictions of habitat required for conservation of species. We estimated resource selection functions (RSFs) across three scales for a threatened ungulate, woodland caribou (Rangifer tarandus caribou), with two objectives: (1) to infer the relative effects of two forms of anthropogenic disturbance (forestry and linear features) on woodland caribou distributions at multiple scales and (2) to estimate scale‐integrated resource selection functions (SRSFs) that synthesize results across scales for management‐oriented habitat suitability mapping. We found a previously undocumented scale‐specific switch in woodland caribou response to two forms of anthropogenic disturbance. Caribou avoided …
