There is little, and often no evidence that spatial models, including those described here, can represent connectivity for the many species or processes that occupy many natural landscapes. The disturbance-based models are used as the basis for the binary representations of connectivity as paths/corridor/linkages through landscapes described below.
Lack of substantial evidence exists to support the notion that spatial models, including those presented, can effectively represent connectivity among various species or processes found in numerous natural settings. Instead, disturbance-based models are employed as a basis for depicting connectivity as networks of routes, corridors, and linkages within landscapes.
