Shannon diversity index h value
WebbMethods: The Shannon diversity index (H) is another index that is commonly used to characterize species diversity in a community.Like Simpson's index, Shannon's index … Webb9 apr. 2024 · Shannon's diversity index H = − ∑ ρ i l n ( ρ i) ρ i is the proportion of the total number of specimens ii expressed as a proportion of the total number of species for all species in the ecosystem. The product of ρ i l n ( ρ i) for each species in the ecosystem is summed, and multiplied by − 1 to give H.
