Blue mussels grew and calcified 7 times faster in the Kiel Fjord (Baltic Sea), where low pH (ocean acidification) conditions prevailed, than at an outer fjord site where pH levels were higher In addition, the mussels were able to outcompete barnacles at the inner fjord, low pH site. Thus, blue ...

Moderate seawater acidification does not elicit long-term metabolic depression in the blue mussel Mytilus edulis

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 ...

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

  • 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 ...

Deep-water prawn Pandalus borealis displays a relatively high pH regulatory capacity in response to CO2-induced acidosis

Deep-water prawns (Pandalus borealis) exposed to severely acidified seawater (pH 6.86) for 16 days were able to compensate by accumulate buffering bicarbonate ions at levels comparable to those reported for shallow-living decapod crustaceans. (Laboratory study)
