Shannon and simpson diversity indices
Webb(do the values increase with increased diversity or decrease?). The Simpson's index (D s ) is the chance that two animals selected from the forest are of the same species. 0 is infinite diversity and 1 is no diversity (all the same species). The lower the value, the greater the diversity. In contrast, the Shannon-Weaver index H measures overall ... WebbThis diversity is known as: Simpson’s index [22] in biology and ecology – where it is used as a measure of biodiversity; Hirschman’s index [23] in economics and competition law – where it is applied as a measure of concentration;1 and participation ratio [24]-[25] in physics – where it is used as a measure of localization.
