The Response of Juvenile King Scallops to Ocean Acidification
Sanders, M.B., Bean, T.P., Hutchinson, T.H. and Le Quesne, W.J.F. 2013. Juvenile king scallop, Pecten maximus, is potentially tolerant to low levels of ocean acidification when food is unrestricted. PLOS ONE 8: e74118.
In discussing their findings, the four researchers state they determined that "none of the exposure levels were found to have significant effects on the clearance rates, respiration rates, condition index or cellular turnover (RNA: DNA) of individuals." And they further note that these findings are compatible with those of Anderson et al. (2013), who also studied the growth, development and survival of the initial larval stages of P. maximus and who only found them to be susceptible to the deleterious effects of ocean acidification at pCO2 levels of 1600 ppm and above. Sanders et al. indicate that these results suggest that "where food is in abundance, bivalves like juvenile P. maximus may display a tolerance to limited changes in seawater chemistry."
