Webbdiversity indices and non-additive statistical mechanics. This makes the Shannon index and the Simpson diversity (or Gini coefficient) special cases of a more general index. The general index includes a parameter q that can be interpreted from a statistical mechanics perspective for systems with an underlying (multi)fractal structure. WebbSimpson's Diversity Index is a measure of diversity which takes into account the number of species present, as well as the relative abundance of each species. As species richness and evenness increase, so diversity increases. n = the total number of organisms of a particular species N = the total number of organisms of ALL species how many characters in license plateWebb10 juni 2005 · The Rao diversity coefficient , which accounts for both phylotype abundance and dissimilarity, was indeed higher for B than for the other subjects (fig.
