As the top carnivore of the alpine and subalpine zones [of Central Asia], the snow leopard strongly influences the numbers and whereabouts of hoofed herds [for example of animals such as sheep, ibex, argali, tahr, goral, serrow, Tibetan antelope or wild yak] over time. That in turn affects plant communities and thus shapes the niches of many a smaller organism down the food chain. The leopard's presence—or absence—affects competing hunters and scavengers too, namely wolves, wild dogs, jackals, foxes, bears, and lynx. This cascade of consequences makes Uncia uncia a governing force in the ecosystem, what scientists term a keystone species.
Which species is functioning as a keystone species, for example, in the European Alps or the Sierra Nevada in the western part of the United States? Is homo sapiens a keystone species?
