The distributional patterns of 12 aquatic and 16 terrestrial cave-limited species from 96 caves in the Greenbrier Valley of West Virginia and nearby limestone areas were analyzed. The analogy between islands and isolated karst areas was examined. For terrestrial species, the area effect was greater on islands, probably because of low immigration and extinction rates. Aquatic species, on the other hand, showed little or no area effect due in large part to high immigration rates. Therefore, migration and extinction rates must be rigorously examined when island analogies are examined.
