WebbSimpson’s Reciprocal Diversity Index 1 O.C.4- Analysis of the biodiversity of two local communities using Simpson’s reciprocal index of diversity. Background: Simpson’s index (D) is a measure of diversity, which takes into account both species richness, and an evenness of abundance among the species present. In WebbDiversity Indices • Usually used as biodiversity (as in species), but can apply to other data where you count the number of times a particular category occurs (e.g. nest shape). • Comprises two components • Species Richness: the number of species in an ecosystem. • Species Evenness: a measure of how abundances are distributed among the species.

WebbSince diversity corresponds to a low value of D and lack of diversity corresponds to a high value, it is better to use 1 – D, which is called Simpson’s index of diversity. This index takes values between 0 and 1. Another measure is Simpson’s reciprocal index of diversity, which is defined as 1/D. This index takes values between 1 and k.

Webb9 apr. 2024 · Whittaker (1972) described three terms for measuring biodiversity over spatial scales: alpha, beta, and gamma diversity. Alpha diversity refers to the diversity within a particular area or ecosystem, and is usually expressed by the number of species (i.e., species richness) in that ecosystem.
