摘要: The San Joaquin kit fox (Vulpes macrotis mutica) is at risk of extinction primarily due to profound habitat degradation, fragmentation, and loss. However, kit foxes inhabit some urban areas, and roads present a potential threat to kit foxes in these areas. From 1998-2004, we investigated the effects of roads on urban kit foxes in Bakersfield, California. Vehicles were the primary cause of mortality for urban kit foxes, and most strikes occurred on arterial roads, which had higher traffic volumes and speed limits. Also, foxes were more frequently struck near intersections between major roads and other linear rights-of-way (e.g., railroads, canals, other roads), which likely were used as travel corridors by kit foxes. Males appeared to be particularly vulnerable to vehicle strikes during the winter mating season.
