Effect of elevated pCO2 on the production of dimethylsulphonioproprionate (DMSP) and dimethylsulphide (DMS) in two species of Ulva (Chlorophyceae)

Intracellular concentration of DMSP remained unaffected in two macroalgae species (Ulva lactuca and U. clathrata) under ocean acidification conditions, but significant differences in extracellular production of DMSP and DMS occurred in U. lactuca. (Laboratory study)

Interactive effects of ocean acidification and warming on subtidal mussels and sea stars from Atlantic Canada

Sea stars collected in Nova Scotia, Canada, grew more slowly under ocean acidification conditions, and their growth rate decreased further with a warmer temperature. In contrast, blue mussel grew more quickly with no response to temperature within the tested range. Predation of sea stars on mussels, measured as per-capita consumption ...

Coralline algal structure is more sensitive to rate, rather than magnitude, of ocean acidification.

When exposed to ocean acidification conditions (pH 7.7) for 80 days, coralline algae survived by increasing their calcification rates. However, those algae for which the pH had been dropped rapidly, rather than slowly and gradually, exhibited weaknesses in their calcite skeletons. (Laboratory study)

Sub-lethal effects of elevated concentration of CO2 on planktonic copepods and sea urchins

Under extreme ocean acidification conditions (pH 6.8), the egg production rates of copepods decreased significantly. For two species of sea urchins, fertilization rate of eggs decreased with increasing ocean acidification conditions. Furthermore, the size of urchin larvae decreased and deformities increased. These effects on marine life could lead to changes ...

Acidification and warming affect both a calcifying predator and prey, but not their interaction

Muscle length and claw strength of green crabs decreased after the crabs had been in ocean acidification conditions (pH 7.7) for 5 months. Periwinkles tended to have weaker shells in response to acidification. Predation by green crabs on periwinkles did not appear to change under ocean acidification conditions. (Laboratory study) ...

Species-specific responses to calcifying algae to changing seawater carbonate chemistry

Two species of phytoplankton (coccolithophores) had higher rates of deformities when pH of seawater in the laboratory was different from present-day ocean pH. Examination of geological samples of coccolithophores did not reveal higher levels of deformities, suggesting that coccolithophores have adapted to changes in ocean pH over geological time. ...

The metabolic response of pteropods to acidification reflects natural CO2-exposure in oxygen minimum zones.

Four species of pteropods from the tropical Pacific Ocean that naturally migrate into low-oxygen waters were not adversely affected when grown under ocean acidification conditions. However, another pteropod species, which does not migrate, responded to ocean acidification conditions with reduced oxygen consumption and ammonia excretion. This indicates that the natural ...
