Representation of A and KS domain diversity between samples using OTU networks. Main nodes (black dots) represent soil samples, nodes at the end of edges (grey dots) represent single OTUs. The distance between main nodes is equal to the similarity between samples. Edges connect OTU nodes to sample nodes. A OTU network was constructed for each dataset (A and KS domain separately), and both networks were investigated and represented using a different node degree to represent a all OTUs, b only location endemic OTUs belonging to each soil sample and c only OTUs shared between different locations (not between the same location) (node degree ≥ 4)
