摘要: Abstract We used locations of 6 wolves (Canis lupus) in Minnesota from Global Positioning System (GPS) collars to compare day-versus-night estimate territory size and location during summer. employed both minimum convex polygon (MCP) fixed kernel (FK) methods. two methods partition GPS for home-range comparisons: (1) daytime = 0800–2000 h; nighttime 2000–0800 (2) sunup versus sundown. Regardless location-partitioning method, mean area MCPs did not differ significantly MCPs. Similarly, FKs (95% probability contour) were different nightime FKs. FK core use areas (50% between nor sundown locations. conclude that similar our study day-only are adequate describing the location, extent summer wolf territories by MCP
