Fig. 6From: New microbiological insights from the Bowland shale highlight heterogeneity of the hydraulically fractured shale microbiomeNetwork analysis of ASVs with abundance of ≥ 1% of the sequences in each given sample based on SPIEC-EASI. A Microbial co-occurrence network. Node’s size represents betweenness centrality. Nodes with betweenness centrality ≥ 1000 are annotated at phylum level. Distinct colors indicate distinct modules. Edges represent interactions between ASVs. B Classification of nodes based on among-module and within-module connectivity, network hubs (purple) and module hubs (orange) in the fractured shale microbiomeBack to article page
