摘要: We identified primary habitat and functional corridors across a landscape using Global Positioning System (GPS) collar locations of brown bears (Ursus arctos). After deriving density, speed, angular deviation movement, we classified function for group animals with cluster analysis. described areas high amounts sinuous movement as patches very directional, fast highly bear corridors. The time between scale analysis influenced the number size identified. Bear should be collected at intervals ≤6 h to correctly identify travel Our corridor identification technique will help managers move beyond theoretical discussion linkage zones active management features that preserve connectivity.
