Control of ambient pH on growth and stable isotopes in phytoplanktonic calcifying algae

Abstract:

The present work examines the relationship between pH-induced changes in growth and stable isotopic composition of coccolith calcite in two coccolithophore species with a geological perspective. These species (Gephyrocapsa oceanica and Coccolithus pelagicus) with differing physiologies and vital effects possess a growth optimum corresponding to average pH of surface seawater in the geological period during their first known occurrence. The “ancestral” C. pelagicus has much wider pH tolerance ...
