Web28 mrt. 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 … Web& Mohler 1983). The second is that beta diversity represents the number of communities present. Since communities in nature are seldom discrete and countable, a given value, say c, of beta diversity in this interpretation is actually equivalent to the amount of heterogeneity that would obtain if there were exactly c distinct communities present.
