WebbShannon or Shannon--Weaver (or Shannon--Wiener) index is defined as H ′ = − ∑ i p i log b p i, where p i is the proportional abundance of species i and b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 (which makes sense, but no real difference). Both variants of Simpson's index ... WebbWe tested several common diversity indices in a range of simple to complex statistical analyses in order to determine whether some were better suited for ...

Webbdiversity richness formula [2]. Simpson’s Species Diversity Index Species richness as a measure on its own takes no account of the number of individuals of each species present. It gives equal weight to those species with very few individuals and those with many individuals. A better measure of diversity should take into account the abundance ... WebbThis is the reason why most researchers have been utilizing more than one index of diversity. Some of the common alpha diversity indices are the following: (1) Chao Index, (2) Simpson Index, (3) Shannon Index, (4) ACE Index, and (5) Good's Coverage Index. Chao Index. Chao index has two types: Chao 1 and Chao 2.
