AB The species-area relationship is one of the strongest empirical generalizations in geographical ecology, yet controversypersists about some important questions concerning its causality and application. Here, using more accurate measures ofisland surface size for five different island systems, we show that increasing the accuracy of the estimation of area hasnegligible impact on the fit and form of the species-area relationship, even though our analyses included some of themost topographically diverse island groups in the world. In addition, we show that the inclusion of general measurementsof environmental heterogeneity (in the form of the so-called choros model), can substantially improve the descriptivepower of models of island species number. We suggest that quantification of other variables, apart from area, that are alsocritical for the establishment of biodiversity and at the same time have high explanatory power (such as island age,distance, productivity, energy, and environmental heterogeneity), is necessary if we are to build up a more predictivescience of species richness variation across island systems.
