A scale-free approach to subtaxon-to-taxon ratios

Abstract

Subtaxon-to-taxon ratios such as the species-to-genus ratio have been frequently used in ecology and biogeography despite their well-known sample size dependence. For instance, any subtaxon-to-taxon ratio is an increasing function of the area sampled. Hence, its validity as an ecological indicator is problematic at best. This drawback can be avoided by constructing taxon-subtaxon curves. Owing to their scale-free nature, taxon-subtaxon curves standardize the information in subtaxon-to-taxon ratios allowing for meaningful comparison of datasets.
