Blue mussels from the Baltic Sea grew less when raised for seven weeks under ocean acidification conditions and with limited food algae. Corrosion of the internal shell surface occurred at a range of ocean acidification levels when food supply was low. When food supply was high, corrosion occurred only in ...
Swimming performance of Atlantic cod was not impaired after they had lived under ocean acidification conditions for 4 or 12 months. They did not have different metabolic rates, critical swimming speeds, or aerobic scope compared to those that lived in non-acidified seawater. (Laboratory study)
This study investigated how 16 intertidal seaweed species from southern Spain used inorganic carbon under different levels of ocean acidification conditions. (Laboratory study)
The heat tolerance of a crab species was affected higher concentrations of carbon dioxide. (Laboratory study)
Juvenile Atlantic cod exposed to ocean acidification conditions for 55 days had reduced weight gain, growth rate, and condition. Growth trajectories of those living in medium and high acidification levels were 2.5 and 7.5 times lower than that of those in the low acidification level. The findings suggest that Atlantic ...
This study investigated the response of metamorphosing larvae of a tubeworm species (Hydroides elegans) to two climate change stressors—ocean acidification (pH 7.6) and low oxygen (hypoxia)—and to both combined. (Laboratory study)
Unlike most marine invertebrates, the common slipper shell broods its embryos in capsules. This study found that the capsules do not protect the embryos from ocean acidification. When brooded under ocean acidification conditions, larvae had shells that were 6 percent shorter, and the percentage of larvae with abnormalities was 1.5- ...
Vegetative growth and production of gametes by kelp from the North Sea (Germany) increased under ocean acidification conditions. (Laboratory study)
When a green seaweed was grown in tidepools for 31 days under ocean acidification conditions, it grew more and had slightly enhanced photosynthesis.
Ocean acidification may alter the biogeographical distribution of a non-calcifying red alga by affecting its photosynthesis and growth. (Laboratory study)
