It may be easier to interpret the result if you calculate the evenness: E = H / ln(k), where k is the number of species. Evenness gives you a value between 0 and 1 (so you can think of it as a percentage). 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. siam makro public company

Webb18 mars 2024 · Simpson’s similarity index is used to calculate the similarity between a pair of community samples, to quantify whether their species composition is similar (they share most or all the species) or different. It comes in the company with other, similar indices, like Jaccard and Sørensen, which do the same job but with slightly different logic. WebbSeeing that dominance is the complement of evenness, an equitability index takes its largest value when all species have the same abundance. In this context, species diversity is a function of species richness and evenness; thus as species richness and evenness increase, diversity also increases. Analogous to “Shannon equitability ...
