WebShannon-Weiner Index Another widely used index of diversity that also considers both species richness and evenness is the Shannon-Weiner Diversity Index, originally proposed by Claude Shannon in 1948. It is also known as Shannon's diversity index. The index is related to the concept of uncertainty. WebWe will focus on the inverse Simpson and Shannon diversity estimates and Chao’s richness estimate but this approach can be used for any metric.

WebShannon’s entropy quantifies the amount of information in a variable, thus providing the foundation for a theory around the notion of information. Storage and transmission of information can intuitively be expected to be tied to the amount of information involved. For example, information may be about the outcome of a coin toss. WebLike Simpson’s index, Shannon’s index accounts for both abundance and evenness of the species present. … Equitability assumes a value between 0 and 1 with 1 being complete evenness.

WebTwo of the commonly used measures of evenness are the Shannon index (H) and the Simpson index (D). The Shannon index (H) is a measure of the information content of a community rather than of the particular species that is present. The index is as follows: H=−∑i=1Spilogpi Webbeen successfully applied to measure the Shannon diversity in macrophytes assemblages (Baattrup-Pedersen et al. 2002). With the relative abundances estimated with frequency data, the Shannon ( H) and Simpson ( D) diversity was estimated.
