Morphological adaptations and seasonal weight changes in Blanford's fox, Vulpes cana
Geffen E., Hefner R., Macdonald DW., Ucko M.
Foxes exhibit slight sexual dimorphism, Individuals from the northern location (Ein Gedi) were significantly heavier and had larger body length than the southern population (Eilat). These differences may reflect food abundance. Body weight of adult foxes increased towards winter and decreased in summer. The Blanford's fox is one of the smallest canids, but proportionally this species has the longest tail and the shortest hind legs among the Arabian desert fox species. These features and its naked foot pads and sharp, curved claws reflect adaptations of the Blanford's fox for living in a nearly vertical habitat of rocky mountains and canyons. -from Authors
