3_Species realized light niches

Realized niches of the cyanobacteria and diatoms after 2 days and at the end of the experiments over gradients of daily PAR exposure (E/m2d) and mixing depth (m). - "Subject": "F" stands for Fixed incubation bottles (constant light; "mode"=fix) at 0, 20, 40 and 80 cms depth. "L" stands for Lifted incubation bottles (fluctuating light; mode="lift") from the surface to 50, 100 and 180 cms deep. - "PAR" is the Photosynthetically Active Radiation (E/m2d)
