Webb12 dec. 2024 · Taking both factors into consideration, you can then calculate a diversity index. There are several, but one of the most common ones is the Shannon Diversity Index (also Shannon-Weiner), represented by this formula: To calculate, first count the number of garments you have of each species. Webb13 apr. 2024 · We calculated species richness, Shannon–Wiener index, Simpson's diversity index, Pielou's evenness index, Bray–Curtis similarity, and the sampling adequacy analysis using the “vegan” package (Oksanen et al., 2024). All data were summarized per plot per habitat types during each season.

Transformations of these same data showed that if Shannon's diversity val-ues were plotted against 10g2 of species richness, the plot was linear (Fig. 2).

Webb1 jan. 2024 · Finally, we employed the Shannon-Wiener formula to measure ‘overall’ diversity: H ' = − Σ n i / N · ln n i / N where H′ is the diversity index. Although the original formulation of the index used log 2 , we utilized the natural logarithm ln, as it is computationally simpler, ecologically just as valid, and fulfils the need of standardization …
Webbrichness, for q = 15) it is Shannon diversity, i.e. effective number of species derived from Shannon entropy, and for q = 2 it is Simpson diversity, i.e. ENS for Simpson concentration index. For q > 0, indices discount rare species, while for q < 0 the indices discount common species and focus on number of rare species (usually not meaningful).
