 The Area Law in Island-Biogeography: “the equilibrium number \(S\) of a species of a given taxonomic group on an island (as far as creatures are concerned) increases [polynomially] with the islands area [A]: \(S = c\times A^z\). The (positive-valued) constants \(c\) and \(z\) are specific to the taxonomic group and island group.” (Lange 2000, 235f.; Lange 2002, 416f.)
