- Metabolic depression explains differences in vulnerability to low oxygen between two species of temperate marine bivalves. Winterburn, Keryn Talevi, Jasmine Clarke, Shelby B Clements, Jeff C Coffin, Michael R S Filgueira, Ramón Animals Crassostrea Oxygen Mytilus edulis Eutrophication Bivalvia Nutrient enrichment and rising temperatures increasingly generate summer hypoxia in temperate estuaries, potentially impacting the physiology and survival of sessile marine bivalves. In the western Atlantic ocean, eastern oysters, Crassostrea virginica, and blue mussels, Mytilus edulis, often co-occur in these habitats, but their comparative resilience to extended hypoxia and anoxia is uncertain. In this study, the effects of hypoxia and anoxia on the physiological response and survival of oysters and mussels were examined under summer eutrophic conditions. Survival, respiration, and pumping rates were determined in both species under three treatments: normoxia (>5 mg O L), hypoxia (∼2 mg O L), and anoxia (
