Shannon weiner index of diversity
WebbShannon-Weiner Index. The Shannon-Weiner index (Barnes et al. 1998) was developed from information theory and is based on measuring uncertainty. The degree of uncertainty of predicting the species of a random sample is related to the diversity of a community.

It is most popular to use natural logarithms, but some argue for base b = 2 b =2 (which makes sense, but no real difference).
