Short summary
The ability of marine macroalgae to adapt to changing ocean chemistry will depend on the flexibility of their inorganic carbon uptake mechanisms across biogeographic ranges. Therefore, we investigated the plasticity of inorganic carbon uptake mechanisms in north Atlantic rhodoliths – free-living calcifying red algae that form important benthic habitats in coastal environments. We observed flexible mechanisms related to seawater DIC concentrations, indicating the potential for adaptation.
