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.
There is scarce, and often absent, proof that spatial models, including those discussed here, can depict connectivity for the numerous species or processes inhabiting many natural environments. The disturbance-based models serve as the foundation for the binary representations of connectivity as routes/pathways/connections through landscapes described below.
