Shell growth of blue mussels from the Baltic Sea decreased under ocean acidification conditions. Data suggest that the reduced shell growth under severe acidification did not result from metabolic depression but from increased cellular energy demand and nitrogen loss. (Laboratory study)

Combined effects of ocean acidification and solar UV radiation on photosynthesis, growth, pigmentation, and calcification of the coralline alga Corallina sessilis (Rhodophyta)

When a coralline alga was exposed to both ocean acidification and solar UV radiation, its growth, photosynthesis, and calcification rates were greatly reduced, compared to when it was exposed only to solar UV radiation. The calcified layer of the alga appeared to provide protection from UV. The results imply that ...

Hypoxia and acidification have additive and synergistic negative effects on the growth, survival, and metamorphosis of early life stage bivalves

In larval scallops,ocean acidification (pH 7.4–7.6) reduced survivorship by more than 50 percent. Low-oxygen water inhibited growth and metamorphosis. When exposed to both low oxygen and ocean acidification at the same time, scallops fared worse than under either one by itself. In early life stage clams, low oxygen led to 30 ...

Interactive effects of CO2 and trace metals on the proteasome activity and cellular stress response of marine bivalves Crassostrea virginica and Mercenaria mercenaria

Ocean acidification caused Eastern oysters and hard shell clams to accumulate more metal pollutants, which affected their physiology. (Laboratory study)

Aerobic scope fails to explain the detrimental effects on growth resulting from warming and elevated CO2 in Atlantic halibut

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

Aerobic scope and cardiac performance of Atlantic halibut increased following 14–16 weeks exposure to elevated temperatures and even more so in combination with CO2-acidified seawater. However, the increase does not translate into improved growth. Instead, long-term exposure to CO2-acidified seawater reduces growth at temperatures that are frequently encountered by this ...
