Health and population-dependent effects of ocean acidification on the marine isopod Idotea balthica

The immune responses of grazing isopods (Idotea balthica) in the Baltic Sea dropped by 60 to 80 percent after the isopods were placed in ocean acidification conditions for 20 days. In addition, isopods from a low salinity site, where their health was already compromised, suffered 100 percent mortality when placed ...

Effects of ocean acidification, temperature and nutrient regimes on the appendicularian Oikopleura dioica: A mesocosm study

Appendicularians are free-swimming tunicates that are common in most oceans, coastal waters, and estuaries. They build delicate, gelatinous houses that they use to filter food from the water. This study found that appendicularian abundance increased with ocean acidification, warmer temperatures, and higher nutrient levels. This suggests that appendicularians will play ...

Reviewing the impact of increased atmospheric CO2 on oceanic pH and the marine ecosystem.

The world’s oceans contain an enormous reservoir of carbon, greater than either the terrestrial or atmospheric systems. The fluxes between these reservoirs are relatively rapid such that the oceans have taken up around 50% of the total carbon dioxide (CO2) released to the atmosphere via fossil fuel emissions and other ...

The synergistic effects of increasing temperature and CO2 levels on activity capacity and acid–base balance in the spider crab, Hyas araneus

Spider crabs were not able to fully buffer their internal pH when exposed to ocean acidification conditions for 12 days. Behavior of the crabs was not impaired by ocean acidification conditions or acute heat stress when they happened separately, but it was when both occurred at the same time. (Laboratory ...

Biocalcification in the eastern oyster (Crassostrea virginica) in relation to long-term trends in Chesapeake Bay pH

  • Posted on: Mon, 06/13/2016 - 05:56

Estuarine waters are more susceptible to acidification because they are subject to multiple acid sources and are less buffered than marine waters. Consequently, estuarine shell-forming species may experience acidification sooner than marine species although, the tolerance of estuarine calcifiers to pH changes is poorly understood. This study analyzed 23 years ...

Size-dependent pH effect on calcification in post-larval hard clam Mercenaria spp.

  • By: Anonymous

The shell calcification rates of small hard clams in five size classes (0.39, 0.56, 0.78, 0.98, and 2.90 mm shell height) decreased with increasingly severe ocean acidification conditions (pH 8.02, 7.64, and 7.41). Clams in the larger sizes were able to deposit new shell material even under corrosive conditions. However, ...

Oyster shell dissolution rates in estuarine waters: Effects of pH and shell legacy

  • Posted on: Mon, 06/13/2016 - 05:56

The shells of eastern oysters from the Chesapeake Bay dissolved at faster rates when exposed to increasingly severe ocean acidification conditions. Oysters with fresh shells dissolved at the fastest rate, followed by oysters with weathered shells and those with dredged shells. (Laboratory study)
