摘要: The marine phytoplankton represents the single most important ecosystem on earth as it produces more biomass than all terrestrial ecosystems taken together. Thus, also constitutes an sink for atmospheric carbon dioxide. Earlier studies have shown that many organisms are under UV-B stress even at ambient levels. Phytoplankton is not equally distributed in water column, but rather uses highly specific orientation strategies to move and stay zones of suitable light intensity growth survival.
