Inter- and intraspecific phenotypic plasticity of three phytoplankton species in response to ocean acidification.

ABSTRACT: Phenotypic plasticity describes the phenotypic adjustment of the same genotype to different environmental conditions and is best described by a reaction norm. We focus on the effect of ocean acidification on inter- and intraspecific reaction norms of three globally important phytoplankton species (Emiliania huxleyi, Gephyrocapsa oceanica and Chaetoceros affinis). Despite significant differences in growth rates between the species, they all showed a high potential for phenotypic buffering (similar growth rates between ambient and high CO₂ conditions). Only three coccolithophore genotypes showed a reduced growth in high CO₂ Diverging responses to high CO₂ of single coccolithophore genotypes compared with the respective mean species responses, however, raise t
