WebA Shannon entropy of 6.0 corresponds to 403 equally-common species while a Shannon entropy of 5.5 corresponds to 244 equally-common species. The former is almost twice as diverse as the latter even though the difference in the values of the indices is only 8%. WebDiversity Indices. A diversity index is a quantitative measure that reflects how many different types (such as species) there are in a dataset (a community).These indices are statistical representations of biodiversity in different aspects (richness, evenness, and dominance). When diversity indices are used in ecology, the types of interest are usually …
