Four species of pteropods from the tropical Pacific Ocean that naturally migrate into low-oxygen waters were not adversely affected when grown under ocean acidification conditions. However, another pteropod species, which does not migrate, responded to ocean acidification conditions with reduced oxygen consumption and ammonia excretion. This indicates that the natural ...
Intracellular concentration of DMSP remained unaffected in two macroalgae species (Ulva lactuca and U. clathrata) under ocean acidification conditions, but significant differences in extracellular production of DMSP and DMS occurred in U. lactuca. (Laboratory study)
Exposure of Atlantic herring larvae to ocean acidification conditions resulted in stunted growth and development, poorer condition, and severe tissue damage in many organs. The degree of damage increased at higher levels of ocean acidification. (Laboratory study)
Deep-water prawns (Pandalus borealis) exposed to severely acidified seawater (pH 6.86) for 16 days were able to compensate by accumulate buffering bicarbonate ions at levels comparable to those reported for shallow-living decapod crustaceans. (Laboratory study)
This study showed the effects of ocean acidification on ecosystems at coastal sites where volcanic CO2 vents lower the pH of the water. Along gradients of normal pH (8.1–8.2) to lowered pH (mean 7.8–7.9, minimum 7.4–7.5), typical rocky shore communities with abundant calcareous organisms shifted to communities lacking scleractinian corals ...
A brown seaweed (Fucus vesiculosus) grew more slowly in ocean acidification conditions. Consumption of the seaweed by an isopod (Idotea emarginata) was not affected by ocean acidification or temperature. However, reduced growth of the seaweed at high CO2 concentrations might reduce its capability to recover from intense herbivory.
This study used two methods to estimate the exchange of carbon dioxide between the atmosphere and ocean.
Over the contiguous United States, precipitation, temperature, streamflow, and heavy and very heavy precipitation increased during the twentieth century.
Aerobic scope and cardiac performance of Atlantic halibut increased following 14–16 weeks exposure to elevated temperatures and even more so in combination with CO2-acidified seawater. However, the increase does not translate into improved growth. Instead, long-term exposure to CO2-acidified seawater reduces growth at temperatures that are frequently encountered by this ...
Ocean acidification caused Eastern oysters and hard shell clams to accumulate more metal pollutants, which affected their physiology. (Laboratory study)
