Appendix C. Maximum-likelihood estimates of θ and m, with J = 2000, θ = 100, σ = 0.001 or 0.002, and various dispersal rates from the metacommunity.
TABLE C1. Maximum-likelihood estimates (Etienne 2005) of θ and m, with J = 2000, θ = 100, σ = 0.001 or 0.002, and various dispersal rates from the metacommunity (see the figures for the 95%-confidence envelopes). S is the total number of species.

| FIG. C1. Rank abundance curves of simulation results (thick solid lines) and 95%-confidence envelopes (dashed lines) for a nearly neutral local community of J = 2000, θ = 100, σ = 0.001 under different dispersal rates from the metacommunity. Shown are the 2.5th and 97.5th percentile abundances for each rank estimated from 600 simulated communities. |
