Methods: 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 accounts for both abundance and evenness of the species present. …. Equitability assumes a value between 0 and 1 with 1 being complete evenness.
