Author's Personal Copy J. Comp. Path. 2019, Vol. 167, 60e72 Available online at www.sciencedirect.com ScienceDirect www.elsevier.com/locate/jcpa DISEASE IN WILDLIFE OR EXOTIC SPECIES Dental and Temporomandibular Joint Pathology of the Kit Fox (Vulpes macrotis) N. Yanagisawa*, R. E. Wilson*, P. H. Kass† and F. J. M. Verstraete* *Department of Surgical and Radiological Sciences and † Department of Population Health and Reproduction, School of Veterinary Medicine, University of California, Davis, California, USA Summary Skull specimens from 836 kit foxes (Vulpes macrotis) were examined macroscopically according to predefined criteria; 559 specimens were included in this study. The study group consisted of 248 (44.4%) females, 267 (47.8%) males and 44 (7.9%) specimens of unknown sex; 128 (22.9%) skulls were from young adults and 431 (77.1%) were from adults. Of the 23,478 possible teeth, 21,883 teeth (93.2%) were present for examina- tion, 45 (1.9%) were absent congenitally, 405 (1.7%) were acquired losses and 1,145 (4.9%) were missing ar- tefactually. No persistent deciduous teeth were observed. Eight (0.04%) supernumerary teeth were found in seven (1.3%) specimens and 13 (0.06%) teeth from 12 (2.1%) specimens were malformed. Root number vari- ation was present in 20.3% (403/1,984) of the present maxillary and mandibular first premolar teeth. Eleven (2.0%) foxes had lesions consistent with enamel hypoplasia and 77 (13.8%) had fenestrations in the maxillary alveolar bone. Periodontitis and attrition/abrasion affected the majority of foxes (71.6% and 90.5%, respec- tively). -
The Red and Gray Fox
The Red and Gray Fox There are five species of foxes found in North America but only two, the red (Vulpes vulpes), And the gray (Urocyon cinereoargentus) live in towns or cities. Fox are canids and close relatives of coyotes, wolves and domestic dogs. Foxes are not large animals, The red fox is the larger of the two typically weighing 7 to 5 pounds, and reaching as much as 3 feet in length (not including the tail, which can be as long as 1 to 1 and a half feet in length). Gray foxes rarely exceed 11 or 12 pounds and are often much smaller. Coloration among fox greatly varies, and it is not always a sure bet that a red colored fox is indeed a “red fox” and a gray colored fox is indeed a “gray fox. The one sure way to tell them apart is the white tip of a red fox’s tail. Gray Fox (Urocyon cinereoargentus) Red Fox (Vulpes vulpes) Regardless of which fox both prefer diverse habitats, including fields, woods, shrubby cover, farmland or other. Both species readily adapt to urban and suburban areas. Foxes are primarily nocturnal in urban areas but this is more an accommodation in avoiding other wildlife and humans. Just because you may see it during the day doesn’t necessarily mean it’s sick. Sometimes red fox will exhibit a brazenness that is so overt as to be disarming. A homeowner hanging laundry may watch a fox walk through the yard, going about its business, seemingly oblivious to the human nearby. -

San Joaquin Kit Fox Habitat Use in Urban Bakersfield
SAN JOAQUIN KIT FOX HOME RANGE, HABITAT USE, AND MOVEMENTS IN URBAN BAKERSFIELD by Nancy Frost A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment Of the Requirements for the Degree Master of Science In Natural Resources: Wildlife December 2005 ABSTRACT San Joaquin kit fox home range, habitat use, and movements in urban Bakersfield Nancy Frost Habitat destruction and fragmentation has led to the decline of the federally endangered and state threatened San Joaquin kit fox (Vulpes macrotis mutica). Kit foxes in the San Joaquin Valley occur in and adjacent to several urban areas. The urban kit fox population in Bakersfield has the potential to contribute to recovery efforts, however, little is known about habitat use in the urban environment. Habitat use in the urban landscape was examined in 28 radiocollared adult kit foxes between 1 May 1997 and 15 January 1998. The area of the urban environment needed to meet kit foxes’ ecological requirements varied among the sexes and fluctuated throughout the year. Mean home range size was 1.72 km2 (100% minimum convex polygon estimate) and mean concentrated use area (core area; 50% fixed kernel estimate) size was 0.16 km2. Females had a greater median number of core areas than did males, but core area size did not differ between the sexes. Mean home range size was significantly larger during the dispersal season than during the pair formation and breeding seasons. Home range size was greater for males than females during the breeding season. To assess the extent to which kit foxes were concentrated around limited resources, the percentage of overlap between adjacent kit foxes’ home ranges and core areas was determined. -
Red Fox (Vulpes Vulpes) Story and Photos by Joseph Filo, Sr
Trailside Nature & Science Center - What’s in Your Backyard? Red Fox (Vulpes vulpes) Story and Photos by Joseph Filo, Sr. Park Naturalist In normal times, a great many of us miss what happens in and around our own backyards. With so many of us sheltering in place these days, there is an opportunity to better observe our yards and neighborhoods during those 8, 10, 12 or more hours that we would not ordinarily be home. Such an opportunity presented itself at my home over the last two months. In early April, we first saw a female red fox under our bird feeders (photo). Other than some sections of her fur, she looked quite healthy, in fact, she looked pregnant. She continued to visit on an almost daily basis, eating spilled seed from the feeder, and occasionally stalking a bird or squirrel. She also seemed to be eating some of the fresh young grass shoots. Foxes are omnivores. Although we often think of them hunters, eating mice, voles chipmunks, etc. But they also eat plants, including acorns, grass seeds and fruits. There is some dispute as to whether or not the red fox is native to North America. Red foxes were definitely introduced from Europe, but whether or not they were already here is not known for sure. If they were here, they were not abundant. The North American and Eurasian red foxes were once thought to be two separate species, Vulpes fulva and Vulpes vulpes, respectively. They are now considered a single species. We continued to enjoy watching her visit both our bird feeding stations, then we missed her for a few days. -

Green Tetra Tech EC Bothell, Washington Current address and contact information: *Primary Author: J. Perrine, Biological Sciences Department, California Polytechnic State University, San Luis Obispo, CA 93407-0401 [email protected] **L. Campbell, School of Veterinary Medicine, University of California, Davis, One Shields Avenue, Davis, CA 95616 Perrine, Campbell and Green R5-FR-010 August 2010 NOTES IN PROOF • Genetic analyses by B. Sacks and others 2010 (Conservation Genetics 11:1523-1539) indicate that the Sacramento Valley red fox population is native to California and is closely related to the Sierra Nevada red fox. They designated the Sacramento Valley red fox as a new subspecies, V. v. patwin. • In August 2010, as this document was going to press, biologists on the Humboldt-Toiyabe National Forest detected a red fox at an automatic camera station near the Sonora Pass along the border of Tuolomne and Mono Counties. Preliminary genetic analyses conducted at UC Davis indicate that the fox was a Sierra Nevada red fox. Further surveys and analyses are planned. • The California Department of Fish and Game Region 1 Timber Harvest Program has established a Sierra Nevada red fox information portal, where many management-relevant documents can be downloaded as PDFs. See: https://r1.dfg.ca.gov/Portal/SierraNevadaRedFox/tabid/618/Default.aspx Sierra Nevada Red Fox Conservation Assessment EXECUTIVE SUMMARY This conservation assessment provides a science-based, comprehensive assessment of the status of the Sierra Nevada red fox (Vulpes vulpes necator) and its habitat. -
San Joaquin Kit Fox (Vulpes Macrotus Mutica)
Mammals San Joaquin Kit Fox (Vulpes macrotus mutica) San Joaquin Kit Fox (Vulpes macrotus mutica) Status State: Threatened Federal: Endangered Population Trend Global: Declining State: Declining Within Inventory Area: Unknown Data Characterization The location database for the San Joaquin kit fox (Vulpes macrotus mutica) within its known range in California includes 22 data records from 1975 to 1999. Of these records, none of the 7 documented within the past 10 years were of sufficient precision to be accurately located within the survey areas. Three of these 7 records are located within the ECCC HCP/NCCP inventory area. These records represent sighting within non-native grassland, grazed, and agricultural habitat. This database includes records of individual sightings and locations of occupied, vacant, and natal dens. A moderate amount of literature is available for the San Joaquin kit fox because of its endangered status. Long-term studies have been conducted on the ecology and population dynamics of this species in core population centers at the Elk Hills and Buena Vista Naval Petroleum Reserves in Kern County and on the Carrizo Plain Natural Area in San Luis Obispo County. Numerous surveys have been conducted in the northern portion of the range, including Contra Costa County. Quantitative data are available on population size, reproductive capacity, mortality, dispersal, home-range movement patterns, and habitat characteristics and requirements. A number of models have been developed to describe the species’ population dynamics. A recovery plan for the San Joaquin kit fox has been published. Range The San Joaquin kit fox is found only in the Central Valley area of California. -

KIT FOX Vulpes Macrotis
A-28 KIT FOX Vulpes macrotis Description The small-bodied kit fox closely resembles the swift fox (Vulpes velox) but has larger ears and a more angular appearance. The skull is long and delicate, and The kit fox is the broader at the eyes and more slender at the nose than other North American daintiest of three Vulpes. The ears are set close to the midline of the skull (McGrew 1979, species of Vulpes in Sheldon 1992). The kit fox measures 730 to 840 mm in total length; including a North America 260 to 323 mm tail, 78 to 94 mm ears, and 113 to 137 mm hindfeet. Adult (Fitzgerald et al. weight ranges from 1.5 to 2.5 kg. Females are 15 percent lighter on average 1994). than males (Fitzgerald et al. 1994), but there is no other obvious sexual dimorphism. Tail length averages about 40 percent of total body length—a distinguishing trait, along with the large ears, from swift foxes (Sheldon 1992). The kit fox has a light-colored pelage, variable between grizzled-gray, yellow- gray and buff-gray. The shoulders, flanks and chest range from buff to orange. Guard hairs are tipped black or banded. The underfur is lighter buff or white, and relatively heavy and coarse. The legs are slender and thickly furred. The sides of the muzzle are blackish or brownish, and the tip of the tail is black. The soles of the feet are protected by stiff tufts of hair. Because of its relative coarseness, a kit fox pelt has little market value (O'Farrell 1987). -
