Correction: DNA extraction replicates improve diversity and compositional dissimilarity in metabarcoding of eukaryotes in marine sediments.

Fig 3 is incorrect. The authors have provided a corrected version here.

Fig 3

Rarefaction comparing expected OTU richness of pooled samples (grey lines) and individual replicates (black lines).

Only replicates with more than 15,000 reads were included from the samples Fine Sand (A; n = 5), Coarse Sand (B; n = 7) and Clay (C, n = 5). Panel D shows expected richness in pooled samples compared to mean expected replicate richness. Error bars represent standard error, for pooled samples calculated as described in Heck et al [47].
