Size variation of the fox, Vulpes vulpes in the palaearctic region today, and in Israel during the late Quaternary

Fox size variation, both today over a wide geographic range and during the late quaternary in Israel, was correlated with temperature changes. Competition with the related Asiatic jackal was not considered to have any effect on fox size; the degree of dwarfing of the fox was utilized in a speculative estimate of the Pleistocene—Holocene temperature rise.
