Abstract
We investigated home-range size and spatial arrangement of swift fox Vulpes velox (Say, 1823) between September 1996 and March 1997 in a sagebrush-gra ssland habitat in southeastern Wyoming. Home-ranges ((x) over bar +/- SE, n = 10) averaged 11.7 +/- 1.3 and 7.7 +/- 1.1 km(2) using the 95% adaptive k ernel method and the 100% minimum convex polygon, respectively. Although th e ranges of males seemed about 25% larger compared with females, the differ ence was not significant. Core areas (50% utilization distribution) consist ed of 1 or 2 polygons and averaged 19.0 +/- 2.6% of the total home-range ar ea. Home-range overlap of paired foxes (95% adaptive kernel: 59.6 +/- 7.9%; n = 8 combinations) was significantly greater than range overlap of unpair ed animals (95% adaptive kernel: 9.9 +/- 2.8%; n = 18 combinations). Paired foxes shared more than 70% of their dens. 75% of the dens were located wit hin an individual's core area. Our results suggested that swift foxes were monogamous.
