Figure 6

Correlation-based association network at order level of total (a) and potentially active (b) bacterial communities among land use systems: shrubland, rainfed, freshwater, dam wastewater and untreated wastewater irrigated. Only statistical significant bacterial orders are visualized (p ≤ 0.05). The size of each node is proportional to the taxon relative abundance and the edge width corresponds to the association strength of each taxon with the land use system.
