INTRODUCTION
The tendency for species richness to increase with area (the "species - area relationship") is one of the most robust empirical generalizations in ecology (May 1975, Rosenzweig 1995). Most studies of species - area patterns have focused on particular taxa, guilds, or functional groups, rather than broader comparisons within entire communities. Yet, comparisons of species - area relationships among taxa or functional groups can highlight essential differences in their spatial dynamics and responses to spatial heterogeneity (Kareiva 1994). For instance, biogeographic studies of West Indies vertebrates reveal stronger species - area relationships for ...
