Crustaceans

Some copepods (Calanus species) in the Arctic routinely encounter a range of seawater pH levels each day as they migrate vertically in the ocean; they were not severely affected when exposed [...]

Deep-water prawns (Pandalus borealis) exposed to severely acidified seawater (pH 6.86) for 16 days were able to compensate by accumulate buffering bicarbonate ions at levels comparable to those [...]

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 [...]

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 [...]

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 [...]

Spider crab larvae developed more slowly, grew less, and lower physiological fitness under increasing levels of ocean acidification conditions. (Laboratory study)

Blue mussels grew and calcified 7 times faster in the Kiel Fjord (Baltic Sea), where low pH (ocean acidification) conditions prevailed, than at an outer fjord site where pH levels were higher In [...]

Krill from the northern Atlantic Ocean exposed to ocean acidification conditions for 5 weeks had lower survival rates. (Laboratory study)

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 [...]

The egg production rate, hatching success, and respiration of a Mediterranean copepod were not affected by ocean acidification conditions. Warming and food availability did have some effects. [...]
