At an oyster hatchery on the Oregon coast, researchers found that production of oyster larvae and growth of young oysters dropped when the aragonite saturation state decreased in seawater. (Laboratory study)

Copepods produced more eggs in warmer temperatures, but the increase was smaller when copepods were simultaneously exposed to warmer temperature and ocean acidification conditions (lower pH). When pH changed between egg production and hatching, fewer eggs hatched. Warmer egg production temperature induced a positive maternal effect and increased the egg ...

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

Some like it hot: Temperature and pH modulate larval development and settlement of the sea urchin Arbacia lixula

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 ...

Effects of low pH and raised temperature on egg production, hatching and metabolic rates of a Mediterranean copepod species (Acartia clausi) under oligotrophic conditions.

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. (Laboratory study)
