Marine calcifiers exhibit mixed responses to CO2-induced ocean acidification

Eighteen marine species exposed to ocean acidification conditions for 60 days exhibited a wide range of responses. Ten of the 18 species were affected negatively with lower rates of net calcification and, in some cases, net loss of shell. Those species included temperate corals, pencil urchins, hard clams, conchs, serpulid ...

Extracellular acid–base regulation during short-term hypercapnia is effective in a shallow-water crab, but ineffective in a deep-sea crab

Experiments with deep-sea and shallow-water crab species from the U.S. west coast indicated that deep-sea animals, which are adapted to a stable environment and have reduced metabolic rates, lack the short-term acid–base regulatory capacity to cope with the sudden, large increases in carbon dioxide that would occur if carbon dioxide ...

Tolerance of juvenile barnacles (Amphibalanus improvisus) to warming and elevated pCO2

The Kiel Fjord (Baltic Sea) has large natural variations in carbon dioxide levels. When barnacles from the fjord were raised for 8-12 weeks in warmer seawater under ocean acidification conditions, their growth and condition did not change significantly. Warming increased the shell strength, but ocean acidification conditions had only weak ...

Multigenerational exposure to ocean acidification during food limitation reveals consequences for copepod scope for growth and vital rates

The copepod Calanus finmarchicus had reduced growth, development, and fecundity when exposed to ocean acidification conditions. However, offspring in the next generation did not have delayed development, suggesting that the species may have an ability to adapt to ocean acidification. The results also suggest that in a more acidified ocean ...

Tolerance of Hyas araneus zoea I larvae to elevated seawater pCO2 despite elevated metabolic costs

Spider crab larvae that developed under ocean acidification conditions had higher metabolic rates. However, the larvae seem to be able to compensate for higher metabolic costs as their development time and survival was not affected. (Laboratory study)
