Webb11 okt. 2024 · Shannon or Shannon–Weaver (or Shannon–Wiener) index is defined as H = -sum p_i log (b) p_i, where p_i is the proportional abundance of species i and b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 (which makes sense, but no real difference). WebbBiodiversity - The number of different species of organisms in a particular environment. Evenness (E) - A measure of how similar the abundances of different species are in the community. Shannon-Weiner index (H) - This diversity measure came from information theory and measures the order (or disorder) observed within a particular system. diddy kong racing key locations
