Rarefaction curves from experimental data sets.

<p>Evolution of ACE, Chao1 and OTUs figures with the sample size. The continuous line represents the OTUs distribution at 3% dissimilarity, the dotted and dashed lines represent the evolution of Chao1 and ACE respectively, with sample size. The selected datasets are Priest Pot lake, grassland FMG1 pooled SF3+SF4 maize rhizosphere and ERR011062 faecal sample to measure diet influence on gut microbiota; all were analysed after cleaning and chimera removal.
