Response to technical comment on `meta-analysis reveals negative yet variable effects of ocean acidification on marine organisms'




Ecology Letters (2011) 14: E1–E2


It has been proposed that crustaceans should be excluded from a comparison of biological responses to ocean acidification among organisms with different calcium carbonate (CaCO3) forms in their calcified structures. We re-analysed our data without crustaceans and found high variation in organismal responses within CaCO3 categories. We conclude that the CaCO3 polymorph alone does not predict sensitivity, and a consideration of functional differences among organisms is necessary for predicting variation in response to acidification.
