According to the original formula … WebbS = number of species, = species richness H m a x = l n ( S) = Maximum diversity possible E = Evenness = H H m a x Example Problem Statement: The samples of 5 species are 60,10,25,1,4. Calculate the Shannon diversity index and Evenness for these sample values. Sample Values (S) = 60,10,25,1,4 number of species (N) = 5

Shannon Diversity Index Calculator with Formula
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 ... Simpson's diversity (D1), Simpson's dominance (D2), Simpson's evenness (E), and Berger-Parker dominance (BP). We calculated each of these indices for herbaceous plants, arbuscular ... WebbLet's try an example using the data from Field 1 in Table 13.1. Below are the steps to solve the Simpson Index of Diversity. Calculate 1. n-1 for each species 2. n (n-1) for each species 3. the sum of all values for n (n-1) 4. N. by adding all the values for n, and N (N-1) 5. fitness center near chicago il
