Bryozoan colonies that came from larger larvae survived better, grew faster, and reproduced sooner or produced more embryos than colonies that came from smaller larvae. These effects crossed generations, with colonies from larger larvae themselves producing larger larvae.
This article provides an overview of how rivers, which tend to be acidic compared to the ocean, affect shellfish, with a focus on the Gulf of Maine.
Exposure to extreme ocean acidification conditions (pH 6.95) did not affect growth of adult female copepods. However, only 4 percent of their eggs successfully yielded larvae.
Common periwinkles had lower shell growth rates and less increase in shell thickness when grown in ocean acidification conditions, warmer temperatures, or both. Shells were also less pointed and more rounded. Those changes in shell growth appeared to result from disruption of the periwinkle's metabolism. (Laboratory studied)
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 ...
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 ...
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)
