Range expansions seen recently may be connected to anthropogenic landscape change and not the spread of exotic European populations. DNA comparisons show that the eastern American red fox is closely related to native populations in Canada and the northeastern region of the United States and is, therefore, the result of natural range expansions and not an invasive species from Europe as was previously thought. Despite claims of historical translocations from Europe, modern red fox populations in the United States' southeastern region have been shown to be native to North America. North American red foxes are genetically distinctive from their Eurasian counterparts. More recently, the Wisconsin glaciation (100,000 to 10,000 before present) separated the North American red fox population into two distinct areas. ![]() Phylogeographical and genetic analysis of the American red fox suggests that red foxes first migrated to North America during the Illinoian glaciation (300,000 to 130,000 years before present) and spread southward. While it is claimed that Vulpes vulpes fulva stems from a non-native population that spread westward from European introduction, a historical analysis of firsthand accounts does not support this claim. Vulpes vulpes is usually seen either as an exotic species introduced by Europeans during the colonization of the North American continent or as a hybrid between European and North American red foxes. North American colonization and native status Ĭurrent literature discusses whether or not the red fox is native to North America, with some research suggesting that nearly all red fox populations in North America are not native. This subspecies is most likely the ancestor of the domesticated silver fox. It is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, occurring in North America. The American red fox ( Vulpes vulpes fulva) is a North American subspecies of the red fox. ![]()
