Hundred Years of Environmental Change and Phytoplankton Ecophysiological Variability Archived in Coastal Sediments
Figure 1
Cell concentration and pH as a function of time.
Cell concentrations (A–F) and pH levels (G–L) are shown according to sediment core layer (age-depth) for the 18 Pentapharsodinium dalei strains tested at salinity 15 and 30. Points represent mean values of three replicates and bars represent s.e.m. (standard error of the mean). *1–strains for which upper pH limits could not be determined (see Results section); *2–strain for which upper pH limits were reached after 65 days.
