WebThe Shannon diversity index is one of several statistical indices used to measure species richness. There are several other diversity indices such as Simpson’s index and the … 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.
What does the Shannon Wiener index tell us? - KnowledgeBurrow
WebShannon or Shannon–Weaver (or Shannon–Wiener) index is defined as H' = -\sum_i p_i \log_ {b} p_i H ′ =−∑i pi logb pi, where p_i pi is the proportional abundance of species i i and b b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 b =2 (which makes sense, but no real difference). WebShannon index Shannon index 1) where S = species richness, pi = relative abundance of species i, log = usually natural logarithm (i.e. loge or ln) (or Shannon entropy2), Shannon-Wiener or (incorrectly) Shannon-Wiever; denoted as H, H’ or HSh) considers both species richness and evenness. The index is derived from information theory and pilari englanniksi
