Figure 6 in A dataset on earthworm communities in French Guiana

Figure 6. Patterns of earthworm alpha diversity at different spatial scales in rainforests of French Guiana: (A) Rarefaction curve showing how the number of OTUs observed at a regional scale increases as a function of the number of sampled landscapes; the solid line represents the rarefaction curve; the shaded area represents the 95 % confidence interval based on a bootstrap with 200 replications; (B) Rarefaction curves showing how the number of OTUs observed at the landscape scale increases as a function of the number of sampled communities; confidence intervals were not represented to keep the figure legible; (C) Alpha diversity at the different spatial scales, with Microhab = microhabitat, Com = community, Hab = habitat and Land = landscape level); (D) Sample coverage at the community scale.
