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 ...

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 ...

Maternal effects may act as an adaptation mechanism for copepods facing pH and temperature changes

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

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 ...

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

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