The Effect of Salinity Changes Upon the Physiology of Eulittoral Green Macroalgae from Antarctica and Southern Chile: II INTRACELLULAR INORGANIC IONS AND ORGANIC COMPOUNDS
The effects of hypo- and hypersaline treatments ranging from 7–68% on the intracellular inorganic ion and organic solute concentrations were determined in the eulittoral green macroalgae Ulothrix implexa, Ulothrix subflaccida, Enteromorpha bulbosa, Acrosiphonia arcta , and Ulva rigida from Antarctic...
