Shannon diversity index formula excel
WebbShannon-Wiener Index is defined and given by the following function: H = ∑ [ ( p i) × l n ( p i)] Where − p i = proportion of total sample represented by species i. Divide no. of individuals of species i by total number of samples. S = number of species, = species richness H m a x = l n ( S) = Maximum diversity possible E = Evenness = H H m a x Webb29 mars 2024 · The Shannon Diversity Index is a way to measure the diversity of species in a community.
