Short summary

Coccolithophores are important unicellular algae with a calcium carbonate covering that might be affected by ongoing changes in the ocean due to absorption of CO₂, warming, and melting of glaciers. We used the southern Patagonian fjords as a natural laboratory, where chemical conditions are naturally highly variable. One variant of a widespread coccolithophore species can tolerate these conditions, suggesting it is highly adaptable, while others were excluded, suggesting they are less adaptable.
