A Keystone Species

Scientist Paine defines the keystone species as a species that has a disproportionately large effect on its environment related to its abundance. The concept of keystone species was introduced in 1969. Keystone species is a Predator who prevents the particular herbivorous species from eliminating the dominant plant species. It plays a critical role in maintaining the structure of an ecological community, affecting the other organism in an ecosystem and help to determine the type of as well as  number of various other species in the community. The role of this species is analogous to the role of the keystone in an arch on which the entire load of the structure stands. It overlap with the several other species conservation concept such as flagship species, indicator species and umbrella species. For example the Jaguar is an umbrella species, flagship species and wilderness quality indicator. The Jaguar is a keystone species in subtropical and tropical America.
