vulpes fulva การใช้

Historically, red foxes were classified as two species : " Vulpes vulpes " in Eurasia and " Vulpes fulva " in the Americas ( Tesky, 1995 ).
Since 1959 they have been considered to be a singular species of " Vulpes vulpes ", with " Vulpes fulva " one of the ten subspecies ( Hall, 1981; Kamler & Ballard, 2002 ).
Previous classifications and taxonomic uncertainties ( Kamler & Ballard, 2002 ) frame populations of " Vulpes vulpes fulva " as a nonnative, invasive species that can cause declines in the populations of native species, carrying capacities, and populate regions at higher densities ( Kamler & Ballard, 2002 ).
The identification of the origins of the North American red fox populations is crucial in conservation efforts aimed at native versus nonnative species ( Statham et al ., 2012 ) . " Vulpes vulpes fulva " s presence has been augmenting in the west, an area in which it has not been shown to be native.
