Fig 1. The median growth rate, and mean (± S.E.) pCO₂ and maximum dark-adapted photochemical efficiency (F_v/F_m) of Trichodesmium erythraeum IMS101 when acclimated across a range of temperatures, light intensities, and at three target pCO₂ concentrations (Low = 180 ppm, Mid = 380 ppm and High = 720 ppm) (174 treatments).

For the temperature response: LL = 40 μmol photons m^-2 s^-1; HL = 400 μmol photons m^-2 s^-1. Note the dashed line represents the initial pCO₂ concentration for each treatment culture once diluted (T = 0), while the data points are the final CO₂ concentration post culturing.
