William Cooper established the world’s longest-running study of this process within six quadrats in Glacier Bay. Studies of this process often make use of chronosequences or permanent sample plots. This process can begin through mechanisms of facilitation, tolerance, (10[1])or inhibition in Connell and (10[1])Slatyer’s model of its autogenic type. This process occurs in stages called seres (-5[1])(“sears”). As this process continues, opportunistic r-strategists are gradually replaced by K-selected (-5[1])species (10[1])that form an equilibrium climax community. The “primary” form of this process happens when lichens and other pioneer species colonize an area devoid (10[1])of soil, while its “secondary” form often follows a flood or forest fire. (10[1])For 10 points, name this process of change in an ecological community over time. ■END■ (10[1]0[4])
