The rarefaction option is useful to compare communities with much different numbers of individuals sampled, which might bias diversity comparisons (Gotelli & Colwell 2001). Ecol. The most commonly used index of beta diversity is β_w = S/α - 1, where S is the total number of species, and α is the average number of species per site (Whittaker 1960). Kembel and J.F.
