Fig. 3From: Quantifying multiple-site compositional turnover in an Afrotemperate forest, using zeta diversityProbability of retention for species of a given level of occupancy. The probability is calculated as ζn + 1/ζ n (red dots), representing the probability that a species of a given level of occupancy (n) will be retained in one extra site. The blue curve represents the prediction from the power law decline of zeta diversity (see Fig. 4)Back to article page
