WebbShannon or Shannon--Weaver (or Shannon--Wiener) index is defined as H ′ = − ∑ i p i log b p i, where p i is the proportional abundance of species i and b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 (which makes sense, but no real difference). WebbDer Shannon-Index (häufig auch Shannon-Wiener-oder Shannon-Weaver-Index) ist eine mathematische Größe, die in der Biometrie für die Beschreibung der Diversität (vgl.

Webb14 okt. 2024 · The Shannon-Wiener Index is based on the relative frequency of species and assumes that individuals are randomly sampled from a very large community (Shannon and Wiener 1949 ). The Simpson Diversity Index emphasizes the most abundant species and has limited sensitivity to species richness.
