For example: if I have two communities where 1-D (community 1) = 0.92 1-D (community 2) … WebbIt is important to distinguish ‘richness’ from ‘diversity’. Diversity usually implies a measure of both species number and ‘equitability’ (or ‘ evenness ’). Three types of indices can be distinguished: 1. Species richness indices: Species richness is a measure for the total number of the species in a community (examples Fig. 1a).

"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.
