Archaeal Communities in a Heterogeneous Hypersaline-Alkaline Soil

Figure 3

Shared taxonomic groups and operational taxonomic units (OTUs) at 97% cut-off in alkaline-saline soils of the former lake Texcoco with different electrolytic conductivity and pH. (a) Venn diagrams of cooccurrence of taxonomic groups. (b) Network plot of occurrence of OTUs. OTU-nodes (white circles) are connected via edges (lines) to sample-nodes (large circles) in which their sequences are found. Edge weights (lines’ length) are defined as the number of sequences in an OTU.
