Multidimensional Species Concept

Defines a species as a set of morphologically distinct populations, possible without clinal gradation, that are dispersed geographically yet that form a network and are capable of replacing each other. Since the individual populations may be regarded by other researchers as morphospecies, the multidimensional species concept is an extreme form of lumping.

Cf. nondimensional species concept, the phenetic species concept, and typology.
