(Figure 19.11) These graphs show that succession is associated with a rapid increase in species richness that slows and levels off over time. How might you explain a graph showing succession with an initial increase in species richness followed by a decline in species richness over time?

If there is inhibition in the community, certain species will dominate and prevent the establishment of new species. Over time, the species richness will decline as a result of this inhibition. This pattern is seen in some types of succession, particularly in communities dominated by long-lived species with persistent woody biomass.
