Sea urchin larvae from the Mediterranean Sea survived at higher rates under ocean acidification conditions, but they grew smaller. Warmer temperatures increased survival and growth rates of the larvae. The results suggest that ocean acidification and warming could boost populations of the sea urchin, increasing its impact on shallow Mediterranean ...

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 ...

Sea urchins living in ocean acidification conditions for 45 days grew less. They were able to actively maintain the pH outside the cells in their bodies. (Laboratory study)

Volcanic carbon dioxide vents show ecosystem effects of ocean acidification

This study showed the effects of ocean acidification on ecosystems at coastal sites where volcanic CO2 vents lower the pH of the water. Along gradients of normal pH (8.1–8.2) to lowered pH (mean 7.8–7.9, minimum 7.4–7.5), typical rocky shore communities with abundant calcareous organisms shifted to communities lacking scleractinian corals ...

In green sea urchins from the Baltic Sea, the spines appear to be vulnerable to ocean acidification, which might reduce the urchins' protection against predators. Intestinal epithelia may play a role in mediating acid-base balance in the urchin. (Laboratory study)
