Succession and Change of the Ecosystems | SpringerLink
Ecological succession describes the process of change in the ecosystem. In ecological succession, we can distinguish several stages, called "stages of succession". Although we call them stages, they are a series of continuous changes. As to landscape development, we can identify processes at macro, meso, and micro scales.
