The process described is ecological succession, which occurs when a disturbance eliminates most or all of the species in a community and new communities form over time. Rejuvenation refers to a restoration of vigor or vitality, but it does not necessarily involve changes in species composition. Mass extinction refers specifically to a widespread and rapid elimination of species, but it does not describe the process of ecological succession. Patch dynamics refers to the spatial and temporal changes in patches of habitat, but it is not a process of community change in response to disturbance.
