WHEN TO SLOW DOWN: ELK RESIDENCY RATES ON A HETEROGENEOUS LANDSCAPE
It remains unclear if patterns of habitat use are driven by animals moving to and increasing residency time in selected areas, or by animals simply returning frequently to selected areas. We studied a population of North American elk (Cervus elaphus) in the Chequamegon National Forest, Wisconsin, to...
