An index is proposed for measuring similarity between sets of biota over space and time. It integrates into a single measure hitherto separate and often incompatible procedures, based on species presence-absence and species composition. The index is demonstrated by a hypothetical set of data. When compared with the more usual indices of similarity, the proposed index is found to demonstrate greater rigor and hence greater powers of discrimination between data sets. The S H′ index is applied to… CONTINUE READING
