Allopatric Distribution of Organisms

 

the geographic distribution of species (genera, families, and others) in which the species are separated—that is, not encountered on the same territory. Subspecies from one species always have an allopatric distribution: for example, the gray crow (in Europe, except Western Europe, and Asia—in the East as far as the Enisei) and the black crow (in Western Europe and Asia—to the East of the Enisei).
