In keystone species The starfish Pisaster ochraceus is a keystone species in … When starfish were removed, the diversity of the community plummeted. Paine coined the term keystone species to describe species that, like the starfish, have disproportionately large impacts on their communities. Witness scientist Bob Paine’s breakthrough discovery of keystone species, through his ingenious experiment with tidepool starfish.

Dr. Ecologist Robert Paine, who coined the term “keystone species” in the 1960s, observed the importance of such species in a study of starfish along the rocky Pacific coastline in Washington state. Explore how Paine designed this experiment and made his discovery with this classroom poster. He dubbed these movers and shakers “keystone species,” and ecology has never been the same since. Starfish, such as the ochre sea star (Pisaster ochraceus) and the reef sea star (Stichaster australis), have become widely known as examples of the keystone species concept in ecology. The first keystone species ever identified was the predatory purple sea star (Pisaster ochraceus), found along the rocky coasts of Makah Bay in … (image source: wikipedia) In the bay were a bunch of California mussels (Mytilus californianus). This predatory starfish feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities. Indeed, trophic cascades have been discovered across the globe, where keystone predators such as wolves, lions, sharks, coyotes, starfish, and spiders shape communities. Tide Shifts Against the Concept of a Keystone Species Starfish challenge a key ecological concept, ushering in a slightly-more democratic era for tide pools everywhere In many cases, the vital role of a keystone species in an ecosystem is not fully appreciated until that species is gone. And if they were, then keystone species and trophic cascades might be general features of ecosystems—rules of regulation that governed the numbers and kinds of creatures in a community. Some species exert undue influence in an ecosystem, while other species have little impact. The starfish Pisaster ochraceus is a keystone species in the rocky marine intertidal communities off the northwest coast of North America. Robert Paine, the guy who originally came up with the idea of keystone species was studying invertebrates in Makah Bay, Washington, USA. In honor of Dr. Paine’s life and career, take a look at the 1966 research that led to the keystone species concept.
