The effects of ocean acidification on feeding and contest behaviour by the beadlet anemone Actinia equina

Increasing concentrations of atmospheric carbon dioxide are causing oceanic pH to decline worldwide, a phenomenon termed ocean acidification. Mounting experimental evidence indicates that near-future levels of CO2 will affect calcareous invertebrates such as corals, molluscs and gastropods, by reducing their scope for calcification. 239 more words


Combined effects of ocean acidification and temperature on planula larvae of the moon jellyfish Aurelia coerulea


• We addressed the impact of ocean acidification and seawater temperature increases on scyphozoan planulae.
A. coerulea planulae can cope well with decreased pH conditions through rapid settlement. 263 more words
