Probability 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)
