Eight adult red foxes (Vulpes vulpes) were radio tracked during the summers of 1978 and 1979 in an alpine and subalpine environment of northwest British Columbia. The spatial distributions of small mammals (mice, voles, and shrews) and arctic ground squirrels (Spermophilus parryii) were ascertained to complement the telemetric study. Summer home ranges averaged 1611 ha (range = 277–3420 ha) and were larger than vulpine ranges in temperate environments. Significant habitat selection was evident in five of the seven home ranges that were examined. Salix shrub communities were preferred habitats, whereas, open lichen – Empetrum and fen communities were avoided. Relative densities of small mammals and arctic ground squirrels varied significantly among plant communities. Possible explanations, considering the diet of the fox and the spatial distribution of its prey, are offered to account for the observed patterns of home-range size and habitat utilisation.

We used radiotelemetry to study the effects of food addition and predator reduction on the home-range sizes of adult Arctic ground squirrels (Spermophilus parryii) on large-scale experimental grids in the boreal forest of the southwestern Yukon Territory. Home ranges were 2-7 times smaller on food-supplemented grids than on nonsupplemented grids, regardless of whether large mammalian predators were present. Similarly, core areas (where 50% of activities occur) were 8-11 times smaller on food-supplemented grids. Food availability rather than predator presence primarily determined the sizes of home ranges and core areas of Arctic ground squirrels.

Male Activity

Three adult red foxes (Vulpes vulpes) in a 20-km2 wilderness area of coastal south-eastern Australia were studied during pre-denning and denning. Home ranges were defined by geographic featues, but not by roads. The foxes occupied exclusive home ranges, and observations suggest that they were territorial and existed alone or, at most, in mated pairs. Home-range sizes were small (1.2-5.2 km2) compared with those in North America and Europe, but similar to those in England and Wales. During denning the female's activity became almost entirely diurnal. When not active, the vixen was with the cubs. Male activity during denning was nocturnal, but, as found for the female, inactive periods were spent near the suspected den-site in his home range. Habitats that were frequented most by all foxes were those with the highest abundance of either small or medium-sized mammals. Dry sclerophyll forest was used consistently by all foxes but heathland and the beaches were rarely frequented. Small and medium-sized mammals, which were abundant in all habitats except the beach and heathland, made up 52.6% of items in the scats.

The Individual

Thirteen red foxes (Vulpes vulpes) were radio-tracked between September 1989 and August 1993 in the Swiss Jura mountains. Home ranges of subadult and adult resident foxes did not differ and were small (seasonal estimates 0.48–3.06 km2). A nomadic adult was also monitored; it used a significantly larger area (12.71–25.90 km2). In most cases, home range sizes did not vary seasonally and were not affected by drastic changes in food availability. That foxes maintain a constant territory size is in accordance with both the "contractor" and "obstinate" strategies. The small observed sizes suggest that after the eradication of rabies, rural areas of central Europe are very good habitats for foxes. In the absence of clumped feeding patches or constraining factors (e.g., deep snow cover), the foxes moved regularly throughout their home range, typically in a "non-oriented zigzag." The distance travelled per day seemed to be affected only by home range size (positive correlation) and occasionally, according to the individual, by weather or snow cover. On average, the foxes moved 3.9–12.0 km a day. Despite its significantly larger home range, the nomadic fox did not move more than the resident foxes; the physical characteristics of red foxes probably set a limit to the distance travelled daily.

Range Dynamics

Changes in red fox home range size in relation to environmental and intrinsic factors were studied using radio-telemetry during 2006–2008 in Ikh Nart Nature Reserve, southeastern Mongolia. We captured a total of 12 red foxes (8 females and 4 males) and fi tted them with VHF radio-collars. Marked animals were tracked up to fi ve times a week to estimate home ranges. We also trapped small mammal and insects in different biotopes for 3 years to estimate relative abundance of prey. Our results showed that mean individual home range sizes varied widely and differed among years. There was variation in home ranges between adults versus juveniles, but no signifi cant difference was found between males versus females. In addition, mean home range size did not differ seasonally for pooled years. Variation in home ranges was best explained by a model that included covariates of year and age. We suggest that spatiotemporal changes in resource availability across years infl uenced home range dynamics of red foxes in our study.

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.

We described the size and spatial arrangement of aggregate and seasonal home ranges for 17 radio-tagged resident Fishers (Martes pennanti) that were >1.5 years old in two areas of central British Columbia during 1990-1993 and 1996-2000. We estimated home range size for each Fisher from the 95% isopleth of the utilization distribution generated using a fixed kernel model with smoothing selected by least-squares cross-validation (95% FK). For comparison to previous studies, we also calculated the minimum convex polygon estimate of home range size (MCP) for each animal. The aggregate home ranges (95% FK) of female Fishers (mean = 37.9 km², SD = 18.5, range = 10.5 – 81.2, n = 11) were significantly smaller than those of males (mean = 161.3 km², SD = 100.0, range = 46.0 – 225.2, n = 3; P = 0.019). We observed minor overlap among 95% FK home ranges of Fishers of the same sex, but considerable overlap among home ranges of males and females. Home ranges (95% FK or MCP) that we observed in central British Columbia were larger than those reported elsewhere in North America, particularly for males. We suggest that the distribution of resources for Fishers may occur at lower gross densitiesin central British Columbia than in other portions of the Fisher’s range and that suitable habitat in which Fishers can establish home ranges is not found uniformly across the landscape.

Between 1983 and 1986, various aspects of red fox spatial behaviour were studied in both rural and semi-urban environments in central Victoria. Using radio-telemetry, the short-term home ranges of three adult foxes (2 male, 1 female) in a pasture/woodland habitat were estimated to be of the order of 5-7 km2 each. In a semi-urban environment nearby, the home ranges of a further 3 adult animals (2 male, 1 female) were estimated to be 0.6-1.3 km2 each. Estimates of home range size based on a 90% space utilisation effectively halved the home range area for all six foxes. There were indications that, for the animals concerned, ranges were mutually exclusive except in the case of a breeding pair which shared a common home range. During the studies, 137 young fox cubs were ear-tagged and released at the point of capture. Subsequently, 46 of these animals were returned by hunters. Nearly 70% of the returned animals were killed at a distance of 2 km or less from the tagging site but dispersal distances of up to 30 km were recorded. The average dispersal distance for animals killed more than 2 km from the tagging site was 11 km. Estimates of fox density in a rural area of some 2400 ha were obtained by a survey of active breeding dens in the 1985 and 1986 breeding seasons. Assuming one breeding pair plus three surviving young per litter, the maximum summer density was estimated at about 3.0 foxes km-2 and the minimum winter density as about 1.2 foxes km-2. For a further estimate of density, 13 foxes were live-captured, fitted with radios and released. In a short control program on the study area a few weeks later, 7 of these animals were recovered in a total sample of 50 foxes killed. The remaining 6 foxes were established as still present in the study area. Using this capturehecapture data, an early autumn density of about 3.9 foxes km-2 was indicated. The significance of this data in relation to the possible role of foxes as vectors of rabies disease in Australia is discussed.

Abstract The red fox (Vulpes vulpes) is one of the most adaptable carnivorans, thriving in cities across the globe. Understanding movement patterns and habitat use by urban foxes will assist with their management to address wildlife conservation and public health concerns. Here we tracked five foxes across the suburbs of Perth, Western Australia. Three females had a core home range (50% kernel density estimate; KDE) averaging 37 ± 20 ha (range 22–60 ha) or a 95% KDE averaging 174 ± 130 ha (range 92–324 ha). One male had a core home range of 95 ha or a 95% KDE covering 352 ha. The other male covered an area of ~ 4 or ~ 6 times this: having a core home range of 371 ha or 95% KDE of 2,062 ha. All five foxes showed statistically significant avoidance of residential locations and significant preference for parkland. Bushland reserves, golf courses, and water reserves were especially preferred locations. Foxes moved quickest (i.e. commuting) when they were in close proximity to roads and slowest (i.e. foraging) when they were further from roads. We compare these findings with a review of the literature for urban fox home ranges. The movement patterns we describe are likely to be common for urban foxes, with half of the published home range estimates for urban foxes (principally based on VHF data) excluding data for ‘lost’ individuals or animals that showed ‘excursions’. It is likely that the home range estimates for these urban exploiters have therefore been grossly underestimated to date. Further application of GPS trackers that allow remote download will vastly improve our understanding of the space use of urban foxes.
