WebbScience, Education, Culture And Lifestyle 2024 WebbThe popular Shannon entropy - Σ p i ln p i (often called the Shannon-Wiener or Shannon-Weaver index in biology) exhibits the same problem as the Gini-Simpson index, though to a lesser degree. If we start with a continent that has 30 million equally common species, and a meteor impact wipes out half the species, this index drops by only 4%.

WebbAccording to Shannon (1948; see also Shannon and Weaver 1949), a general communication system consists of five parts: − A source S, which generates the message to be received at the destination. − A transmitter T, which turns the message generated at the source into a signal to be transmitted. WebbIn the Shannon index, p is the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), ln is the natural log, Σ is the sum of the calculations, and s is the number of species. The Simpson index is a dominance index because it gives more weight to common or dominant species.
