- Nóta 1) “Patches” are spatial units differing from their neighbors. They are not necessarily internally homogeneous, but may be further decomposable to smaller spatial scales. For example, a forest ecosystem is composed of stands of trees, but each stand is composed of individual trees. By studying the dynamics of patches over space and time, ecologists have sought to address one of the fundamental matters in ecology—understanding the linkages between pattern, process, and scale. This theme underpins landscape ecology, disturbance ecology, and the spatial aspects of population ecology, which is the basis for metapopulation theory and metacommunity theory.2) Ecosystem demography models define patches based on age since disturbance and simulate the dynamics of cohorts of similar plant functional types rather than tracking every individual.
