More stopovers are required He conducted this experiment along the shores of Washington State in the 1960s where he removed a species of starfish (sea star) from an area and observed its effects on the other animals. As they are often the start of the food chain, losing keystone plants can cause effects across the food chain, affecting herbivores and the carnivores that eat them by providing less plant matter. That might not be the case when it comes to keystone prey. Two main flyways are used for the southbound return /Resources 11 0 R Importance of Keystone Species. During an experiment, the zoologist, Robert Paine removed all the sea stars in a given area to observe the effect.
