Impacts of Deepwater Horizon oil and associated dispersant on early development of the Eastern oyster Crassostrea virginica.

Geohistorical records indicate no impact of the Deepwater Horizon oil spill on oyster body size

Documentation of the near- and long-term effects of the Deepwater Horizon (DWH) oil spill, one of the largest environmental disasters in US history, is still ongoing. We used a novel before-after-control-impact analysis to test the hypothesis that average body size of intertidal populations of the eastern oyster (Crassostrea virginica) inhabiting impacted areas in Louisiana decreased due to inc...

Survival, Acid–base Balance, and Gaping Responses of the Asian Oyster Crassostrea Ariakensis and the Eastern Oyster Crassostrea Virginica during Clamped Emersion and Hypoxic Immersion

The eastern oyster Crassostrea virginica has a remarkable ability to withstand low oxygen conditions; however, many of the biochemical mechanisms by which that tolerance is accomplished remain poorly understood. In addition, little is known about hypoxia tolerances and adaptations of the Asian oyster Crassostrea ariakensis. By comparing these closely related species, we may learn more about the...

Physiological response and resilience of early life-stage Eastern oysters (Crassostrea virginica) to past, present and future ocean acidification

The Eastern oyster, Crassostrea virginica (Gmelin, 1791), is the second most valuable bivalve fishery in the USA and is sensitive to high levels of partial pressure of CO2 (pCO2). Here we present experiments that comprehensively examined how the ocean's past, present and projected (21st and 22nd centuries) CO2 concentrations impact the growth and physiology of larval stages of C. virginica. Cra...
