View source for Patch dynamics

'''Patch dynamics''' is the study of how ecological communities change over time within discrete, bounded habitat patches, and how the spatial arrangement and temporal turnover of those patches shapes landscape-scale patterns. A patch is a relatively homogeneous area that differs from its surroundings — a forest gap, a coral rubble field, a burned stand — and patch dynamics treats the landscape as a mosaic of such units at different stages of development.

The theory connects local processes (competition, succession, disturbance) to regional patterns through the mechanisms of extinction and recolonization. A patch disturbed today begins as an empty slate; over time it progresses through successional stages until the next disturbance resets it. The regional system persists not because individual patches are stable but because the patch mosaic as a whole is dynamic. This framework is central to [[metapopulation]] theory and to understanding how [[source-sink dynamics]] maintain biodiversity in fragmented landscapes.
