The effects of ocean acidification on living marine resources present serious challenges for managers of these resources. An understanding of the ecosystem consequences of ocean acidification is required to assess tradeoffs among ecosystem components (e.g. fishery yield, protected species conservation, sensitive habitat) and adaptations to this perturbation. We used a ...
Few studies have evaluated the joint effects of elevated temperature and pCO2 on marine organisms. In this study we investigated the interactive effects of Intergovernmental Panel on Clinate Change predicted temperature and pCO2 for the end of the 21st century on key aspects of larval developm,ent of the American lobster, Homarus americanus, an otherwise well-studied, ...
Sea urchin larvae from the Mediterranean Sea survived at higher rates under ocean acidification conditions, but they grew smaller. Warmer temperatures increased survival and growth rates of the larvae. The results suggest that ocean acidification and warming could boost populations of the sea urchin, increasing its impact on shallow Mediterranean ...
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 ...
Ten species of zooplankton displayed a range of mortality rates when exposed to ocean acidification conditions. Differences in in swimming behavior, food habits, size, and presence of gills were not significantly related to sensitivity to lowered pH. The results suggest that marine zooplankton are more sensitive than freshwater zooplankton to ...
The combined effect of ocean acidification and rising temperature enhanced the sensitivity of a red alga to ultraviolet (UV) radiation. This was reflected in an increased damage rate, decreased repair rate, and decreased ratio of repair to damage in thalli. The findings suggest that ocean acidification and warming will reduce ...
Four species of copepods differed in their survival, egg production, and egg hatching success when exposed to ocean acidification conditions for 8 days. (Laboratory study)
Survival of dispersing larvae represents a critical bottleneck that influences the population size of zebra mussels.
This article provides an overview of how rivers, which tend to be acidic compared to the ocean, affect shellfish, with a focus on the Gulf of Maine.
Viability of copepod eggs and larvae was not affected by exposure to ocean acidification conditions. In contrast, warming by 2 or 4°C increased the viability of some eggs. (Laboratory study)
