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

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)

Gene expression profiling in gills of the great spider crab Hyas araneus in response to ocean acidification and warming

The Arctic spider crab (Hyas araneus) appears to have a threshold of ocean acidification beyond which it fails to acclimate. In a 10-week experiment, it had a limited ability to adjust to effects of ocean acidification with and without also experiencing a warmer temperature. (Laboratory study)

Acclimation conditions modify physiological response of the diatom Thalassiosira pseudonana to elevated CO2 concentrations in a nitrate-limited chemostat

A species of phytoplankton changed how it used carbon and energy when it was exposed to higher CO2 levels. The effects differed depending on whether the CO2 level change happened over 15-16 generations versus 33-57 generations. (Laboratory study)

Effects of seawater pCO2 and temperature on shell growth, shell stability, condition and cellular stress of Western Baltic Sea Mytilus edulis (L.) and Arctica islandica (L.)

Blue mussels and ocean quahogs from the Baltic Sea appeared to tolerate wide ranges of seawater temperature and ocean acidification over a period of 13 weeks. (Laboratory study)
