Ecosgstebl A lion EcosgsteB1 B WebbI have calculated their variance, as it is done in the original paper by Simpson regarding measures of diversity and I have calculated a confidence interval for each of them using the formula: ( S − 2 var, S + 2 var), as suggested in a published paper. What I would like to find is a p-value of the null hypothesis that the two indices are equal.

Webb28 mars 2024 · First, we quantified dissimilarity in species composition between each pair of surveys using the Simpson beta-diversity index, which is known to be richness-independent (Koleff et al., 2003). This index ranges between 0 (similar species composition between two surveys) and 1 (no shared species) and is suited to presence-only data and … Webb12 sep. 2024 · The Simpson’s reciprocal index quantifies biodiversity by taking into account richness and evenness. The greater the biodiversity in an area, the higher the value of D. The lowest possible defined value of D is 1and would occur if the community contained only one species. onn technologies
