Fig. 2 | Rarefaction curves showing the effect of increasing sample size on the number of hyperdominants, total species,hyperdominant percentage and fitted values of Fisher's α in tropical tree communities. a–d, The effect of increasing sample size on the number of hyperdominants (a), total species (b), hyperdominant percentage (c) and fitted values of Fisher's α (d) in tropical Africa (magenta),Amazonia (cyan), Southeast Asia (blue). Rarefied data (mean values across iterations of subsamples) are shown as points joined by lines for clarity,shaded areas represent 95% confidence intervals (derived via the s.d. across iterations of subsamples taken with replacement at each sampling point).Note that resampling for rarefaction was by subsampling of plots,but curves are re-plotted on an x axis of number of stems.
