Figure 3

Non-metric multidimensional scaling (NMDS) of total (a) and potentially active (b) bacterial community composition of all samples from land use systems, shrubland, rainfed, freshwater, dam wastewater and untreated wastewater irrigation and dry and rainy season based on weighted Unifrac87 distance matrices. Environmental parameters that were significantly correlated (p ≤ 0.05) to bacterial community structure are indicated by arrows.
