FIGURE 2.13 Ecosystem development: conceptual frame.
*At a time scale of years, decades, and centuries changes occur in their number and nature
or in their range of fluctuations, intensity, and frequency. Their impact on populations and
biocoenose composition lead to time-delayed and long-term effects.
**Ecosystem development is a long-term process that involves a long series of successive
phases of growth and evolution.
