Webb23 aug. 2024 · The upper intertidal zone was recorded to have the highest diversity and an evenness index (Shannon-Wiener a diversity index: H’= 2.524 and Pielou evenness index: J’= 0.932) compared to the middle and lower zones. It can be concluded that the diversity index in the study location is categorized as moderate and its evenness is high. Webb11 okt. 2024 · Shannon or Shannon–Weaver (or Shannon–Wiener) index is defined as H = -sum 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). i pho saigon inver grove heights
