Web"High values of H would be representative of more diverse communities. A community with only one species would have an H value of 0 because Pi would equal 1 and be multiplied by ln Pi which would equal zero. If the species are evenly distributed then the H … WebTwo of the commonly used measures of evenness are the Shannon index (H) and the Simpson index (D). The Shannon index (H) is a measure of the information content of a community rather than of the particular species that is present. The index is as follows: H=−∑i=1Spilogpi

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. Webbeen successfully applied to measure the Shannon diversity in macrophytes assemblages (Baattrup-Pedersen et al. 2002). With the relative abundances estimated with frequency data, the Shannon ( H) and Simpson ( D) diversity was estimated.
