WebbWhen the two communities are completely distinct, the modified Lande similarity is (1/ (1-0.998)) / (1/ (1-0.999)) = 0.50. This makes intuitive sense; if the two communities are completely different, the total pooled diversity is twice the diversity of any single community, so the average community contains half the total pooled diversity.
