The effects of ocean acidification on living marine resources present serious challenges for managers of these resources. An understanding of the ecosystem consequences of ocean acidification is required to assess tradeoffs among ecosystem components (e.g. fishery yield, protected species conservation, sensitive habitat) and adaptations to this perturbation. We used a ...

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 ...

When larvae of blue mussels were kept in ocean acidification conditions predicted for 2100 (pH 7.6) there was no marked effect on fertilization, development, abnormalities, or feeding. However, although the mussel larvae were able to form shells, after two months of exposure they were 28 percent smaller than larvae raised ...

Impact of exposure to elevated pCO2 on the physiology and behaviour of an important ecosystem engineer, the burrowing shrimp Upogebia deltaura

A species of burrowing shrimp was able to tolerate ocean acidification conditions (pH 7.64) for 35 days. At a lower pH of 7.35, individuals experienced extracellular acidosis, suggesting they had little or no buffering capacity, although there was no evidence of negative impacts on metabolism, osmotic regulation, shell mineralogy, growth, ...
