Fig. 3: PCA plots of the bacterial community structure.
From: Microbial communities across activated sludge plants show recurring species-level seasonal patterns
A Differences across plants for growing bacteria, B seasonal differences for growing bacteria in each plant, C differences across plants for disappearing bacteria, D seasonal differences for disappearing bacteria in each plant. R2 values show the explained variance by the grouping variable (A, C: WWTP; B, D: Season).
