Abstract:
Abstract;Ocean acidification (OA) resulting from anthropogenic emissions of carbon ;dioxide (CO2) has already lowered and is predicted to further lower surface ;ocean pH. There is a particular need to study effects of OA on organisms living ;in cold-water environments due to the higher solubility of CO2 at lower ;temperatures. Mussel larvae (Mytilus edulis) and shrimp larvae (Pandalus ;borealis) were kept under an ocean acidification scenario predicted for the ;year 2100 (pH 7.6) and compared against identical batches of organisms held ;under the current oceanic pH of 8.1, which acted as a control. The temperature ;was held at a constant 10°C in the mussel experiment and at 5°C in the shrimp ;experiment. There was no marked effect on fertilization success, development ;time, or abnormality to the D-shell stage, or on feeding of mussel larvae in ;the low-pH (pH 7.6) treatment. Mytilus edulis larvae were still able to develop ;a shell in seawater undersaturated with respect to aragonite (a mineral form of ;CaCO3), but the size of low-pH larvae was significantly smaller than in the ;control. After 2 mo of exposure the mussels were 28% smaller in the pH 7.6 ;treatment than in the control. The experiment with Pandalus borealis larvae ran ;from 1 through 35 days post hatch. Survival of shrimp larvae was not reduced ;after 5 wk of exposure to pH 7.6, but a significant delay in zoeal progression ;(development time) was observed.;;;;;;;;;;;;;
