Abstract: | The responses of division rate, cell volume, cellular carbon (C) and nitrogen (N), cellular pigments and optical characteristics
to changes in salinity were examined in the dinoflagellate Heterocapsa circularisquama. The physiological and optical characteristics of H. circularisquama were significantly affected by changes in salinity. When cells were exposed to different salinities, they exhibited physiological
acclimation by adjusting their cellular properties associated with growth. This could be a beneficial tactic for ensuring
proliferation and limiting damages induced by adverse environmental factors. The results of this study could be essential
for assisting in the development of growth models for H. circularisquama. |
