According to the original formula proposed by Simpson, a higher D D value suggested a community with low biodiversity. … WebbAlpha diversity is a term used to describe the "within-sample" diversity. It's a measure of how diverse a single sample is, usually taking into account the number of different species observed. Alpha diversity metrics are also often weighted by the abundances at which the individual microbes are observed. There are a number of commonly-used ...

Webb1 maj 2024 · Simpson (1949) developed an index of diversity that is computed as: $$D = \sum^R_ {i=1} (\dfrac {n_i (n_i-1)} {N (N-1)})\] where n i is the number of individuals in species i, and N is the total number of species in the sample. An equivalent formula is: $$D = \sum^R_ {i=1} p_i^2\]
