Post-larval development of two intertidal barnacles at elevated CO2 and temperature

Post-larvae of an intertidal barnacle (Elminius modestus) grew more slowly under ocean acidification conditions, but there were no impacts on its shell calcium content and survival by either ocean acidification or warmer temperature. were observed in high CO2 but there were no impacts on shell calcium content and survival by ...

Relative influences of ocean acidification and temperature on intertidal barnacle post-larvae at the northern edge of their geographic distribution

Ocean acidification (pH 7.7) impaired growth and development of an intertidal barnacle (Semibalanus balanoides), but warmer temperature (+4 °C) did not. The mineral composition of the shells did not change with either ocean acidification or warmer temperature. The combination of reduced growth and maintained mineral content suggests that the barnacles ...

Ocean acidification induces multi-generational decline in copepod naupliar production with possible conflict for reproductive resource allocation.

A species of copepod (Tisbe battagliai) had decreased reproduction and growth when exposed to ocean acidification conditions. Over time, these changes could result in smaller brood sizes, smaller females, and perhaps later maturing females, which could destabilize the food web. (Laboratory study)

Relationship between CO2-driven changes in extracellular acid-base balance and cellular immune response in two polar echinoderm species

Green sea urchins were able to adjust their internal pH level within 5 days after being placed in ocean acidification conditions, but sea stars (Leptasterias polaris) were not. Internal pH did not appear to be related to immune response. (Laboratory study)

Near-future level of CO2-driven ocean acidification radically affects larval survival and development in the brittlestar Ophiothrix fragilis

Brittlestar larvae died within 8 days after being transferred into acidified seawater (pH 7.9). The larvae had reduced growth and abnormal development and body structure. The brittlestar used in this study, Ophiothrix fragilis, dominates the seabed ecosystem off northwestern Europe, and the findings suggest that ocean acidification could lead to ...

Effect of ocean acidification on early life stages of Atlantic herring (Clupea harengus L.)

When Atlantic herring eggs were fertilized, incubated, and hatched in ocean acidification conditions, there was no effect on embryo development or hatch rate. There was also no clear relationship between ocean acidification and length, weight, yolk sac area, or otolith area of the newly hatched larvae. However, the larvae did ...

Vulnerability of early life stage Northwest Atlantic forage fish to ocean acidification and low oxygen

For three ecologically important estuarine fish species—inland silverside, Atlantic silverside, and sheepshead minnow—the early life stages were more sensitive to low oxygen than they were to low pH. The combination of low oxygen and low pH had the biggest effect. The results suggest that ocean acidification and hypoxia may reduce ...

Environmental salinity modulates the effects of elevated CO2 levels on juvenile hardshell clams, Mercenaria mercenaria

For juvenile hard-shell clams, ocean acidification alone or in combination with low salinity reduced the hardness and fracture toughness of their shells. This may reduce protection against predators. Salinity should be taken into account when predicting the effects of ocean acidification on estuarine bivalves. (Laboratory study)

Interactive effects of salinity and elevated CO2 levels on juvenile eastern oysters, Crassostrea virginica.

When juvenile oysters were exposed to ocean acidification and/or low salinity, they had greater mortality, less energy stored in their tissues, and loss of soft tissue indicating energy deficiency. Ocean acidification and low salinity also reduced the hardness and fracture resistance of their shells. (Laboratory study)
