Impacts of pH and salinity on community composition, growth and cell morphology of three freshwater phytoplankton

Impacts of climate change on phytoplankton species are very focusing issues nowadays. This research explored the probable impacts different pH (pH 5.90 to 9.10) and salinity (0.60 3.0 ppt) concentrations freshwater Chlorella vulgaris, Euglena granulata Scenedesmus quadricauda. The initial community composition was 4:2:1 for three taxa, which changed 6:3:1, 6:2:1, 6:3.5:1 9:4:1 in 5.90, 9.10 2.20 ppt respectively. E. showed more tolerance a wide range 8.30) based growth rate studies. other two rates reduction gradually changes with concentrations. Conspicuous total biomass were seen 9.10, conditions. Moreover, significant cell morphology found salinity. authors concluded that as group, Chlorophytes susceptible than diatom these variable conditions, while S. quadricauda comparatively vulnerable single species.
