Extended Data Fig. 2: Impact of spatial clustering of plots on rarefaction curves of hyperdominant percentage (first row) and Fisher’s Alpha (second row) in the Amazonia data.
From: Consistent patterns of common species across tropical tree communities
Purple points and confidence intervals represent the full data; black points and confidence intervals represent a subset of the data in which one plot is sampled from each spatial cluster of plots; other coloured points represent subsets of the data in which 2,3,4,…,10 plots (or the total number of plots in the cluster) are sampled from each spatial cluster of plots. Points give the mean values across iterations of subsamples. Confidence intervals are derived via the standard deviation across iterations of subsamples taken with replacement at each sampling point. Note that although resampling for rarefaction was done by subsampling tree inventory plots, the curves are re-plotted with an x-axis of number of stems.
