Unlike most marine invertebrates, the common slipper shell broods its embryos in capsules. This study found that the capsules do not protect the embryos from ocean acidification. When brooded under ocean acidification conditions, larvae had shells that were 6 percent shorter, and the percentage of larvae with abnormalities was 1.5- ...

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)

Effects of elevated temperature and carbon dioxide on the growth and survival of larvae and juveniles of three species of northwest Atlantic bivalves

Ocean acidification conditions and warmer temperatures reduced the survival, development, growth, and lipid synthesis of hard clam and bay scallop larvae. During the juvenile life stages, ocean acidification negatively affected juvenile eastern oysters and bay scallops, but not hard clams. Larvae were substantially more vulnerable to ocean acidication than juveniles ...

Reduced early life growth and survival in a fish in direct response to increased carbon dioxide

Exposure of early life stages of a common estuarine fish (inland silverside) to ocean acidification conditions expected in the world’s oceans later this century reduced survival by 74 percent and growth by 18 percent. The egg stage was significantly more vulnerable than the post-hatch larval stage. These findings challenge the ...

Hypoxia and acidification have additive and synergistic negative effects on the growth, survival, and metamorphosis of early life stage bivalves

In larval scallops,ocean acidification (pH 7.4–7.6) reduced survivorship by more than 50 percent. Low-oxygen water inhibited growth and metamorphosis. When exposed to both low oxygen and ocean acidification at the same time, scallops fared worse than under either one by itself. In early life stage clams, low oxygen led to 30 ...

Effects of high CO2 seawater on the copepod (Acartia tsuensis) through all life stages and subsequent generations.

Ocean acidification conditions did not affect survival, body size, or developmental speed of a copepod species during any of its life stages. Egg production and hatching rates also did not change among generations of females exposed to ocean acidification conditions. Thus, this copepod appears more tolerant to ocean acidification than ...

Effects of raised CO2 concentration on the egg production rate and early development of two marine copepods (Acartia steueri and Acartia erythraea)

Reproduction and larval development of two copepod species were sensitive to extreme ocean acidification conditions. The hatching rate tended to decrease, and mortality rate of young copepods tended to increase. (Laboratory study)
