This conceptual framework found in \citet{Pendleton_2016} describes the ecological processes that contribute to coral reef growth and maintenance vs. the biological and anthropogenic factors that can work against these processes. Illustrating in general terms some of the reef main constituents species, the ecosystem features important to people, it then highlights the reverse in balance of calcification and decalcification taking place in the Anthropocene. Although this model gives an idea of the stressors and their effect on the reef, it fails to show the cumulative interactions explained in the previous step.
