Shannon index definition
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). WebbShannon is an active listener, pays attention to the detail and is a great partner to work with. She brings a natural sense of curiosity and inquisitiveness to the job.
