Fig. 4: Driving forces of CPR and non-CPR bacteria.
From: Adaption mechanism and ecological role of CPR bacteria in brackish-saline groundwater
Random forest (RF) indicating the potential environmental drivers of variations in the CPR community (a), non-CPR bacteria that co-occurred with CPR (Co-CPR) (b), and non-CPR bacteria that not co-occurred with CPR (Non-Co-CPR) (c). PLS-PM describing the relationships between environmental factors, seasonal groups, geographical factors, non-CPR bacteria that co-occurred with CPR and CPR (d). Numbers adjacent to each arrow denote partial correlation coefficients (significance codes: ***p ≤ 0.001; **p ≤ 0.01; *p ≤ 0.05). R2 values display the proportion of variance explained for each factor. The bar-chart showing the standardized total effect of each factor on the CPR (e) and Co-CPR (f).
