During a succession, different groups of plants grow at a site over time. From about 1900 to 1960, however, understanding of succession was dominated by the theories of Frederic Clements, a contemporary of Cowles, who held that seres were highly predictable and deterministic and converged on a climatically determined stable climax community regardless of starting conditions. Succession was among the first theories advanced in ecology. Changes in temperature and rainfall patterns will promote changes in communities.
