Dissolution: the Achilles' heel of the triton shell in an acidifying ocean

International Atomic Energy Agency (IAEA) Publications

Ocean acidification is expected to negatively impact many calcifying marine organisms by impairing their ability to build their protective shells and skeletons, and by causing dissolution...

Publications

Ocean acidification and pathogen exposure modulate the immune response of the edible mussel Mytilus chilensis

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) is one of the main consequences of increasing atmospheric carbon dioxide (CO2), impacting key biological processes of marine organisms such as development, growth...

Persistence of positive carryover effects in the oyster, Saccostrea glomerata, following transgenerational exposure to ocean acidification

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) is predicted to have widespread implications for marine organisms, yet the capacity for species to acclimate or adapt over this century remains unknown. Recent...

Effect of marine acidification on calcification and respiration of Chlamys farreri

International Atomic Energy Agency (IAEA) Publications

Marine acidification will be an important environmental problem in the near future as a result of persistent emissions of CO2 and dissolution into seawater. In this study, we found that...

Morphology and classification of hemocytes in Pinctada fucata and their responses to ocean acidification and warming

International Atomic Energy Agency (IAEA) Publications

Hemocytes play important roles in the innate immune response and biomineralization of bivalve mollusks. However, the hemocytes in pearl oysters are poorly understood. In the present...

Future herbivory: the indirect effects of enriched CO2 may rival its direct effects

International Atomic Energy Agency (IAEA) Publications

Variation in rates of herbivory may be driven by direct effects of the abiotic environment on grazers, as well as indirect effects mediated by their food. Disentangling these direct and...

Effects of ocean acidification on the metabolic rates of three species of bivalve from southern coast of China

International Atomic Energy Agency (IAEA) Publications

Oceanic uptake of anthropogenic carbon dioxide results in a decrease in seawater pH, a process known as “ocean acidification”. The pearl oyster Pinctada fucata, the noble scallop Chlamys...
