WebbSimpson's Diversity Index is a measure of diversity which takes into account the number of species present, as well as the relative abundance of each species. As species richness and evenness increase, so diversity increases. The value of D ranges between 0 and 1. With this index, 1 represents infinite diversity and 0, no diversity. WebbSimpson index=1-dominance. Measures 'evenness' of the community from 0 to 1. Note the confusion in the literature: Dominance and Simpson indices are often interchanged! Shannon index (entropy). as well as number of taxa. Varies from 0 for communities with only a single taxon to high values for communities with many taxa, each with few …
