Fig. 3. A – Whole eukaryotic microbial community bootstrap-supported UPGMA hierarchical clustering tree based on Bray-Curtis ss-diversity metrics. Metazoa were excluded of this analysis; OTU definition as 98% similarity. Analysis were carried out in Qiime as in Kuczynski et al. 2002; samples were subsampled 100 times selecting 2533 sequences (75% of the smallest subsample). B – Only rare eukaryotic community bootstrap-supported UPGMA hierarchical clustering tree based on Bray-Curtis ss-diversity metrics. Metazoa and abundant OTUs (> 0.1%) were excluded of this analysis; OTU definition as 98% similarity. Analysis were carried out in Qiime as in Kuczynski et al. 2002; samples were subsampled 100 times selecting 125 sequences (75% of the smallest subsample).
