How landscape dynamics link individual- to population-level movement patterns: a multispecies comparison of ungulate relocation data
Aim To demonstrate how the interrelations of individual movements form large-scale population-level movement patterns and how these patterns are associated with the underlying landscape dynamics by comparing ungulate movements across species.Locations Arctic tundra in Alaska and Canada, temperate fo...
