Effects of Roads on Endangered San Joaquin Kit Foxes

Journal of Wildlife Management, 2009
ABSTRACT  San Joaquin kit foxes ( Vulpes macrotis mutica ) occur in central California, USA, and are endangered due to habitat loss and degradation. As the human population of California grows, more roads are being constructed in remaining kit fox habitat.

Swift and kit foxes

2004
AbstractSwift foxes and kit foxes are found in the relatively flat, arid regions of North America. Swift and kit foxes are phenotypically similar, although kit foxes have slightly longer, less rounded ears and weigh less. Although early morphometric comparisons and protein-electrophoresis suggested that these foxes constitute the same species, recent ...

Population dynamics of kit foxes

Canadian Journal of Zoology, 1999
We evaluated data from field studies of kit foxes to identify factors that strongly influence or regulate their population dynamics. Two density-dependent regulating mechanisms were detected. First, the rate of juvenile recruitment was inversely related to the density of adult foxes because a higher proportion of juveniles were killed by coyotes at ...

Pathogenesis of blue fox parvovirus on blue fox kits and pregnant vixens

American Journal of Veterinary Research, 1988
SUMMARY To study the pathogenicity of a newly isolated parvovirus of blue fox (Alopex lagopus), pregnant vixens and 43 kits of different ages were experimentally infected with the agent. The kits had no clinical signs of disease, even though most of them excreted virus in their feces, and they responded immunologically to viral exposure.

The San Joaquin Kit Fox

Native to central California, where land is in high demand for development purposes, the San Joaquin kit fox population has been significantly impacted by profound habitat loss. The species remains on the original US endangered species list issued in 1966, with dim prospects for recovery. To guide the work of researchers and conservationists, this book

Factors regulating kit fox populations

Canadian Journal of Zoology, 1997
Recent declines in several populations of kit foxes (Vulpes macrotis) have been attributed to decreased prey abundance and increased coyote-related mortalities. However, it is not known if short-term fluctuations in prey abundance or interference competition by coyotes can regulate the population dynamics of kit foxes.

Coyote – kit fox interactions as revealed by telemetry

Canadian Journal of Zoology, 1994
Red foxes (Vulpes vulpes) avoid areas used extensively by coyotes (Canis latrans), apparently to reduce encounters with coyotes and possible injury or death. It is conceivable that kit foxes (Vulpes macrotis) behave in a similar manner. We used telemetry to examine the spacing patterns and interactions among 24 coyotes and 38 San Joaquin kit foxes (V ...

Observations of Kit Foxes in Southeastern Oregon

Northwestern Naturalist, 1992
The kit fox (Vulpes macrotis) or V. velox macrotis (Dragoo et al. 1990) is found in desert and shrub steppe ecosystems throughout much of the southwestern United States and northwestern Mexico (Samuel and Nelson 1982). The species reaches the northern extent of its range in southeastern Oregon and southwestern Idaho. Vulpes v. macrotis is restricted to
