WebbShannon-Weiner index (H) - This diversity measure came from information theory and measures the order (or disorder) observed within a particular system. In ecological studies, this order is characterized by the number of individuals observed for each species in the sample plot (e.g., biofilm on a plexiglass disc). WebbBiodiversity Calculator.

Webb24 juni 2024 · From Margalef’s 1957 paper onwards, Shannon’s formula (Equation (1)) went on to become the most frequently used abundance-sensitive biodiversity measure for species in ecosystems [ 25 ]. Krebs and Pielou [ 26, 27] acknowledged Margalef as the first to suggest the use of this formula.
