Webb9 feb. 2024 · The Shannon index measures uncertainty about the identity of species in the sample, and its units quantify information (bits; Hurlbert 1971), while the Gini–Simpson (1 − Simpson's original index) measures a probability, specifically, the probability that two individuals, drawn randomly from the sample, will be of different species (Simpson 1949, … 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. flagstaff physical therapistsWebbThis index, developed by Shannon and Weaver for use in information theory, was successfully transferred to the description of species diversity in biological systems (Shannon 1948). Here it is applied to quantify the diversity and the evenness of an elevational distribution of las points. It makes bins between 0 and the maximum elevation. canon picks
