Spread of wolves in the world

The grey wolf historically inhabited each habitat of the Northern Hemisphere (from about 20°of northern geographical latitude up to the Pole) in which large even-toed mammals were to be found (Mech, 1995). The grey wolf belongs to the ecological niche of predators to large mammals of the Earth\'s Northern Hemisphere. Besides the wolf this niche comprises also the mountain lion (Felis concolor) of the North America and the tiger (Panthera tigris) and the leopard (Panthera pardus) of Asia, but the wolf is the most valuable predator owing to his high density of population and considerably wider spread (Mech, 1970).
