摘要

The Equilibrium Theory of Island Biogeography (ETIB) attempts to explain how island area and island isolation can affect patterns of species diversity. Studies that evaluate the effect of area on the diversity of one taxonomic group with different environmental requirements and dispersal abilities for each life stage may provide additional insight into the validity of this theory. The effects of various physical and chemical habitat parameters, including area, on adult and larval dragonfly species diversity were investigated in twenty-eight desert sinkholes. As predicted by the ETIB, both adult and larval species diversity increased with increasing sinkhole surface area, but the slopes of the respective species-area curves indicate that the sinkholecomplex functions as a mainland landscape for adult dragonflies and as an island system for larval dragonflies. Although water chemistry had more influence on species diversity than did area in this system, the ETIB still offers insight into the originand maintenance of this community.
