Rabies Control

During 1989-1992, 33 Red Foxes (Vulpes vulpes) were fitted with radio-collars in metropolitan Toronto to study their behaviour which would provide data to assist with the design of a rabies control strategy for urban areas of Ontario. Annual home range size for adult foxes (avg = 325 ha, SD = 207) was significantly larger than that of juvenile foxes (avg = 165 ha, SD = 176), but we could not detect any seasonal differences in home range size for foxes. Mean (SD) nightly ranges were 38.3 ha (48.3) in spring, 97.4 ha (115.4) in summer, 26.8 ha (28.5) in fall, and 16.3 ha (13.6) in winter. Movements by foxes during the period from June to November averaged 3.5 km (2.89). Eleven of the foxes were known to have dispersed (? 3 km from their home range), but we could not detect a mean direction of dispersal. Thirty-six percent (4/11) of the foxes dispersed in December and 18% (2/11) dispersed in August, with the remainder dispersing between February and November. Average dispersal distance was 19.3 km (15.6), and a significant negative correlation was detected between initial home range size and dispersal distance of foxes. Mortality of radio-collared foxes was caused by collisions with automobiles, predation, and shooting. Foxes made extensive use of ravines and other greenbelt areas, such as parks and golf courses. Residential areas were also used by some foxes. Knowledge of the habitats frequented by foxes as well as their movement potential assisted researchers in determining where vaccine baits should be placed for the control of rabies in Red Foxes in metropolitan Toronto.

The red fox (Vulpes vulpes) is a major predator of Australian wildlife and livestock, but relatively few data exist on fox home-range size and movements in agricultural landscapes. We used radio-telemetry to measure variability in fox home-range size and overlap, and to quantify nightly movements in farmland in south-eastern Australia. Home-range estimates were calculated using the Minimum Convex Polygon (MCP) and Kernel Contours methods. Fourteen foxes were radio-tracked, with home-range size varying from 287 to 3574 ha (mean = 1177 ha, ±920 ha (s.d.), n = 10 foxes) based on the 100% MCP and 151–3196 ha (mean = 639 ha, ± 930 ha (s.d.), n = 10 foxes) based on 95% Kernel. Home-range overlap was greater between subadults than adult foxes; especially at the core home-range level where adult home ranges were virtually exclusive. The average (minimum) area covered by adult foxes during a 12-h nightly period was 383 ha (±347 ha (s.d.), range = 136–1446 ha, n = 4 foxes). The minimum (straight-line) distance travelled by adult foxes during a night was 4.8–16 km (mean = 9.4 km, ± 3.7 km (s.d.), n = 4 foxes). Through continuous radio-tracking, we found that foxes habitually travel over the same ground when moving between foci of interest. Our results improve understanding of fox ranging behaviour in the agricultural landscapes of southern Australia.

Kit fox (Vulpes macrotis) life history and ecology has been extensively studied in the Great Basin and California's Central Valley, with fewer studies in hot desert regions resulting in regional knowledge gaps. To augment our understanding of kit fox life history and ecology, we conducted a 2-year radio-telemetry study of the desert kit fox (V. m. arsipus) in southeastern California. Fifty-six desert kit foxes were fitted with morality-sensitive radio collars between October 2012 and August 2014 with individuals located five to seven nights per week to determine home range size and population density. Mean home range was 15.77 ± 1.03 km2 (95% fixed kernel) and 18.48 ± 1.77 km2 (minimum convex polygon), and larger than all, but one previous study. We found no difference in home range size based on sex or year. Home range overlaps were significantly larger for mated (79.3% ± 1.35%) than unmated pairs (20.9% ± 1.01%) and consistent with previous studies. Population size was estimated at 88 individuals using open population models, resulting in an estimated density of 0.34/km2 (range 0.26–0.47/km2) which is higher than previously reported. Our study represents the first home range and population density study for desert kit foxes in California and provided critical knowledge of this understudied kit fox population.
