Succession

생태천이

Definition

The gradual process of change in species composition and community structure over time following a disturbance.

Detailed Explanation

Primary succession begins on bare rock or volcanic lava, where pioneer species like lichens and mosses first colonize and build soil; secondary succession follows disturbances like fire or logging where soil remains. Each successional stage modifies the environment, making it suitable for the next. Climax communities — though debated as a concept — represent a long-term relatively stable endpoint.
