Comparison of Flea (Siphonaptera) Burdens on the Endangered San Joaquin Kit Fox (Vulpes macrotis mutica (Carnivora, Canidae)) Inhabiting Urban and Nonurban Environments in Central Valley, California.
The San Joaquin kit fox (Vulpes macrotis mutica Merriam (Carnivora, Canidae)) is an endangered small carnivore endemic to the San Joaquin Valley of California. Commercial and agricultural land expansion has contributed to the species' decline and invasion of more cosmopolitan species, providing means for potential ecological shifts in disease vector and host species. Fleas are common ectoparasi...
متن کاملCoyote Control to Protect Endangered San Joaquin Kit Foxes at the Naval Petroleum Reserves, California
We investigated the effectiveness of a coyote (Canis latrans) control program implemented to increase numbers of endangered San Joaquin kit foxes (Vulpes macrotis mutica) at the Naval Petroleum Reserves in California (NPRC). Between 1980 and 1985, the kit fox population on NPRC declined approximately 66% while coyote abundance apparently increased. Coyote predation was identified as the primary...
متن کاملLand Use as a Driver of Patterns of Rodenticide Exposure in Modeled Kit Fox Populations
Although rodenticides are increasingly regulated, they nonetheless cause poisonings in many non-target wildlife species. Second-generation anticoagulant rodenticide use is common in agricultural and residential landscapes. Here, we use an individual-based population model to assess potential population-wide effects of rodenticide exposures on the endangered San Joaquin kit fox (Vulpes macrotis ...
متن کاملCoexistence of coyotes (Canis latrans) and red foxes (Vulpes vulpes) in an urban landscape
Urban environments are increasing worldwide and are inherently different than their rural counterparts, with a variety of effects on wildlife due to human presence, increased habitat fragmentation, movement barriers, and access to anthropogenic food sources. Effective management of urban wildlife requires an understanding of how urbanization affects their behavior and ecology. The spatial activ...
متن کاملChemical immobilization of red foxes (Vulpes vulpes).
Red foxes (Vulpes vulpes) were immobilized with one of the following drug combinations: ketamine/xylazine (n = 22), ketamine/promazine (n = 35), ketamine/midazolam (n = 13), or tiletamine/zolazepam (n = 22). Foxes given ketamine/xylazine had the shortest induction and longest recovery times relative to other drug combinations, whereas foxes given ketamine/midazolam had the longest induction tim...
