Thermoregulation by foxes
… be used to predict the responses of unrestrained foxes of different species to naturally occurring thermal stress. The studied species included the red fox (Vulpes vulpes), arctic fox (Alopex lagopus), and kit fox (Vulpes macrotis). The model was used to test hypothesis whether species of foxes …

Population, Home Range, and Dispersal of Red Foxes in East-Central South Dakota
… dispersal movements and summer home range of red foxes (Vulpes vulpes) were studied in east-central South Dakota during 1974 and 1975. The spring population density of foxes on a 23,319 ha study area declined from 9.2 families/township in 1974 to 7.6 families/township in 1975. Fifty-four percent …

Home Range and Habitat Use of Santa Rosa Island Foxes (Urocyon littoralis santarosae)
<p>Island foxes (<em>Urocyon littoralis</em>) are currently listed as federally endangered on four of the six Channel Islands to which they are endemic. The Santa Rosa Island (SRI) population declined by 99% during the 1990’s due to non-native golden eagle (<em>Aguila chrysaetos)</em> predation and …

Home Range, Home Range Expansion, Dispersal, and Mortality of Juvenile Red Foxes in Southeastern South Dakota
… returned 62% of the tags placed on juvenile foxes. During spring, 1977, 15 juveniles and 2 adult red foxes were marked. Three juveniles were subsequently reported as harvested. Trapping (81%) and hunting (14%) accounted for 95% of the reported mortality. The pelt of one juvenile was reported …

Food Habits of Coyotes and Red Foxes in Western South Dakota As Determined By Fecal Analysis
… strategies. Coyotes (Canis latrans) and red foxes (Vulpes vulpes) are the primary canine predators in western South Dakota and are sympatric in distribution. Objectives for this study were to compare seasonal and spatial food habits of coyotes and red foxes and to determine if coyotes and red …

Habitat Selection by Swift Foxes in Badlands National Park and the Surrounding Area in South Dakota
… National Park led an effort to reintroduce swift foxes (Vulpes velox) to the Park and the surrounding grasslands. To assess swift fox population viability in the region, an estimate of habitat suitability was needed. Habitat selection analyses were conducted during fall 2004, spring 2005, and …

Effect of selection for interspecific behavior on stress and conspecific behavior in tame and aggressive foxes
… and their ancestral counterpart. Two strains of foxes developed at the Russian Institute of Cytology and Genetics by selecting foxes solely for behavior, specifically for a friendly or aggressive response to humans, provide a unique model of long-term selection for specific behaviors that allows …

Evaluation of a technique employing the chemosterilant diethylstilbestrol for suppressing reproduction of wild foxes in Virginia
… Virginia; reference areas were also selected. Foxes were pre-conditioned to bait acceptance using molded beef suet. A total of 614 suet baits each containing diethylstilbestrol (50 mg) and oral marker (35 mg of demethylchlortetracycline) were distributed seven times from late January to late …

Red fox ecology and interactions with piping plovers on Fire Island, New York
Red foxes (Vulpes vulpes) have been identified as a key predator of the threatened piping plover (Charadrius melodus) along the U.S. Atlantic coast. However, little is known about coastal red fox ecology, making it difficult to create effective red fox management strategies in these settings. Here, …

Social Organization, Natal Dispersal, Survival, and Cause -Specific Mortality of Red Foxes in Agricultural and Urban Areas of East-Central Illinois
… most by environmental and body condition. Adult foxes with low (0--20%) and high (80--100%) row-crop percentages, and higher capture weights experienced higher survival. Juveniles from larger litters, low capture body fat, and fewer dispersal days had higher survival. Adult survival (0.35) was …

Effect of Coyotes and Release Site Selection on Survival and Movement of Translocated Swift Foxes in the Badlands Ecosystem of South Dakota
… 50 days post-release. I hypothesized that swift foxes released outside of coyote core-use areas would survive at a higher rate than foxes released at random sites. From 2003-2006, 16 adult coyotes were fitted with Global Positioning System (GPS) radio collars and monitored during the pup rearing …

Effects of Canopy Cover and Impervious Surface Cover on Occurrence of Coyotes (Canis latrans) and Gray Foxes (Urocyon cinereoargenteus) throughout the United States
Coyotes (Canis latrans) and gray foxes (Urocyon cinereoargenteus) are habitat generalist species that occupy similar ecological niches and compete for the same food resources. Urbanization may disrupt habitat resources and intensify interspecific competition. Therefore, there is a need to determine …
