Antioxidant efficiency of platynereis spp.(Annelida, Nereididae) under different ph conditions at a CO2 Vent's System
Marine organisms are exposed to a pH decrease and to alteration of carbonate chemistry due to ocean acidification (OA) that can represent a source of oxidative stress which can significantly affect their antioxidant defence systems efficiency. The polychaetes Platynereis dumerilii and P. massiliensi...
