Jul 28, 2017 · The species diversity in a region is investigated by the indices (species richness, evenness and biodiversity) and their common methods of measurement (evenness index: Simpson, Camargo and Smith & Wilson; biodiversity index: Shannon-Wiener, Brillouin and Simpson). It is important to know the suitable index and its measurement Jul 30, 2016 · We first normalized the Shannon index values by body site and calculated the change in diversity using day 0 as the index value. We calculated this change in diversity among all subjects who received amoxicillin, azithromycin, placebo, or no therapy and utilized the means and standard errors to help decipher trends in the data.
H' = value of Shannon-Wiener diversity index pi = proportion of the ith species logepi = natural logarithm of pi. Practice Shannon Wiener Index. ok.
