Spider crabs were not able to fully buffer their internal pH when exposed to ocean acidification conditions for 12 days. Behavior of the crabs was not impaired by ocean acidification conditions or acute heat stress when they happened separately, but it was when both occurred at the same time. (Laboratory ...

Understanding ocean acidification impacts on organismal to ecological scales

Ocean acidification (OA) research seeks to understand how marine ecosystems and global elemental cycles will respond to changes in seawater carbonate chemistry in combination with other environmental perturbations such as warming, eutrophication, and deoxygenation. This paper discusses the effectiveness and limitations of current research approaches used to address this goal. ...

Marine calcifiers exhibit mixed responses to CO2-induced ocean acidification

Eighteen marine species exposed to ocean acidification conditions for 60 days exhibited a wide range of responses. Ten of the 18 species were affected negatively with lower rates of net calcification and, in some cases, net loss of shell. Those species included temperate corals, pencil urchins, hard clams, conchs, serpulid ...

Future oceanic warming and acidification alter immune response and disease status in a commercial shellfish species, Mytilus edulis L.

Ocean acidification and/or warmer temperatures may affect immune response, parasite abundance and diversity, and bacterial infection of blue mussels. (Laboratory study)

Ocean warming, more than acidification, reduces shell strength in a commercial shellfish species during food limitation

After six months exposure, warmer temperatures, but not ocean acidification, significantly reduced the shell strength of blue mussels, which were fed for a limited period of only 4-6 hours per day. The rising temperatures seemed to affect shell strength indirectly, as the mussels apparently re-allocated energy from shell formation to ...

The swimming kinematics of larval Atlantic cod, Gadus morhua L., are resilient to elevated seawater pCO2

Video analysis of Atlantic cod larvae (12 and 27 days post-hatch) showed no significant differences in most aspects of their swimming kinematics when they had been cultured under ocean acidification conditions. (Laboratory study)

Interactive effects of elevated temperature and CO2 levels on metabolism and oxidative stress in two common marine bivalves (Crassostrea virginica and Mercenaria mercenaria)

  • Posted on: Mon, 06/13/2016 - 05:56
  • By: Anonymous

Hard shell clams and eastern oysters exposed to moderate warming and ocean acidification conditions showed no sign of persistent oxidative stress. This indicates that long-term exposure to moderately elevated CO2 and temperature minimally affects the cellular redox status in these bivalve species and that the earlier observed negative physiological effects ...
