WebApr 11, 2024 · One of the essential characteristics of successional succession is the different rates of biomass growth over time. Once the parent community has been destroyed, the ecological niche of the ecosystem is vacant and uninhabited. This creates favorable conditions for its rapid colonization by species of the daughter community. WebCowles described the chronosequence of vegetation along sand dunes, moving from bare sand beach, to grasslands, to mature forests. A chronosequence is a “space-for-time” substitution, where ecologists can predict temporal patterns of vegetation based on a snapshot of an area gradient representing different ages of succession (Figure 1).
