WebPielou index is a way to measure how the species are evenly distributed in a community. The Pielou index value is defined between 0 and 1. 1 represents a community with perfect evenness, and it decreases to zero as the relative abundances of the species diverge from evenness. Pielou index is similar with Simpson (1-D) index, which uses the ...
