Winter movements and habitat use of northern saw-whet owls at Assateague Island, Maryland
… calculated adaptive kernel, harmonic mean, and minimum convex polygon home ranges for comparison of these methods. Habitat composition in 30% home ranges was compared with 95% home ranges and 30% and 95% home ranges were each compared with composition of the entire study area using compositional …

Habitat Use and Spatial Ecology of Blanding's Turtle, Emydoidea Blandingii, on Squaw Creek National Wildlife Refuge, Mound City, Missouri
… range sizes, estimated by 95% fixed kernel and minimum convex polygon methods, were considerably larger for males (890 ha) than for females (94.9 ha) and for other populations of this species. Overland movements were minimal compared to previous studies and were mainly limited to nesting forays. …

Population Characteristics and the Effects of Hunting on BlackBears in a Portion of Northwestern Montana
… range size for adult males (5+ years) using the minimum convex polygon method was 98.7 km2 with a range of 35.5 to 192.6 km2 (n ;: 7). The home range size for adult females was 45.8 km2 with a range of 17.5 to 107.4 km2 (n = 4). Driving open roads was the primary hunting technique used during the …

The Habitat Ecology of Bog Turtles (<i>clemmys Muhlenbergii</i>) in Southwestern Virginia
… consecutive locations, home range estimators (Minimum Convex Polygon [MCP] and cluster analysis), compositional analysis of habitat selection, and measurement of microhabitat variables. Results suggest a random pattern of movement by bog turtles within habitats. Average net movements recorded …

Use of GIS and Remote Sensing Technologies to Study Habitat Requirements of Ocelots, Leopardus pardalis, in south Texas
… animal's home range was calculated using both Minimum Convex Polygon (MCP) and Kernel home range estimators (95% and 50%). Habitat parameters of interest were: soil, land cover, human density, road density, and distance to closest road, city and water body. Ocelots were found to prefer closed …

Cheetah of the Serengeti Plains: A home range analysis
… home range estimates for cheetah used the minimum convex polygon (MCP), assuming asymptotic home ranges and MCP insensitivity to sample size. They reported metrics of home range size and overlap based on only outline methods. I use 6 481 observations of 240 female and 315 male cheetah from …

Population distribution and seasonal resource selection by elk (Cervus Elaphus) in Central Ontario
… of habitat quality on space use using the minimum convex polygon (MCP) and fixed kernel methods. I evaluated resource selection by elk in winter, spring, summer, and fall, from December 2011 to August 2013, using resource selection functions (RSF’s). I used a generalized linear mixed model …

Using Resident Small Mammals to Assess the Habitat Potential of Experimental Biofuels Feedstocks
… Deer mouse home ranges were calculated using the minimum convex polygon method (MCP). 100% MCP was used for the main analysis and 50% MCP was used for cross-validation purposes. Average deer mouse home range across both years was 2,348 m2. Home ranges were negatively correlated with increases in …
