History
The keystone species concept was coined, in 1969, by the zoologist Robert T. Paine, professor emeritus of the University of Washington, to explain the relationship between Pisaster ochraceus, a species of starfish, and Mytilus californianus, a species of mussel. In his classic 1966 paper, Dr. Robert Paine described such a system in Makah Bay in Washington State. This led to his 1969 paper where he proposed the keystone species concept. The concept has been very popular in conservation, deployed in a range of contexts and mobilized to engender support for conservation.
