WebbThe Shannon equation and resulting index is the mathematical foundation of the theory of information, which is linked to entropy (order in a system) and proposed to use as … 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).
