FIGURE 4.

Chloroplast community composition and percent sequence reads in Lake Klostersee (left) and Lake Bergknappweiher (right). Note different intervals on x-axis. (A,B) Relative abundance of chloroplast sequences at the order level (relative abundances < 1% shown as “other”, asterisks mark samples with low sequence number). Dates in black indicate VSBs. Dates in gray indicate the absence of VSBs. (C,D) Relative abundance of Cyanobacteria vs. chloroplast percent sequence reads (note different y-axis).
