Vertical Distribution of Epibenthic Freshwater Cyanobacterial Synechococcus spp. Strains Depends on Their Ability for Photoprotection
Figure 2
Different Synechococcus spp. cultures after exposure to a light intensity of 200 µmol photons·m−2·s−1 for 0 to 8 h.
Bars placed above individual kinetics represent the coloration of cultures prior to light stress exposure (0 h) in order to allow better comparison. The level of pigmentation was quantified (area and pixel values) with help of the ImageJ program [29]. The maximal value was set as 100%.
