WebbA Gini coefficient of one (or 100 percents ) expresses maximal inequality among values (for example where only one person has all the income). - The Gini-Simpson index is the probability of interspecific encounter, i.e., probability that two entities represent different types. - Chao1 estimator is a nonparameteric asymptotic estimator of species richness … Webbeven (Pielou 1969, Kricher 1972). The diversity indices chosen are those of Simpson, Shannon, and McIntosh. 2. Diversity indices Simpson (1949) introduced an index of diversity which is a measure of concentration of species. Its numerical values increase as diversity decreases (Risser and Rice 1971). A common variation of Simpson's index yields el rock and roll no morira jamas https://florentinta.com
