a Bacterial shannon_e index vs salinity and bacterial shannon_e index vs node of sub-network topology; the regression (blue): y = − 40.02x + 406.80, r2 = 0.11; the regression (orange): y = − 1.57x + 13.56, r2 = 0.01. b Archaeal shannon_e index vs salinity and archaeal shannon_e index vs node of sub-network topology; the regression (blue): y = − 83.95x + 260.98, r2 = 0.15; the regression (orange): y = − 7.08x + 10.50, r2 = 0.07. The blue-shaded and orange-shaded sections show 95% confidence intervals
