FIG 1 — Phytoplankton activity and dynamics in the experimental treatments. (A) Rate of CO₂ fixation (primary production); (B) cumulative CO₂ fixation; (C) phytoplankton community photosynthetic yield; (D) extracellular release of the fixed CO₂; (E) concentrations of chlorophyll a (Chla), ratios of Chla to chlorophyll b (Chla:Chlb, indicative of chlorophyte algae), and ratios of Chla to echinenone (Chla:Echin, indicative of cyanobacteria) at the end of the experiment, (F) abundance of Staurastum planktonicum at the beginning and the end of the experiment.
