Abstract

The relative roles of geographical barriers and ecology in determining the faunal composition of islands is discussed in relation to the bats of certain islands off the northern coast of South America. A complete list of the bats of these islands is given, largely compiled from the literature, but also including some new records. On these islands ecological differences play a much more important role than does the presence of permanent water gaps in determining the number of species a given island supports. The applications of these findings to the somewhat different problems encountered in the Greater Antilles is discussed and a hypothesis involving interaction of water barriers and ecology is presented to explain certain characteristics of the West Indian bat fauna.
