To predict effects of climate change and possible feedbacks, it is crucial to understand the mechanisms behind CO₂ responses of biogeochemically relevant phytoplankton species. Previous experiments on the abundant N₂ fixers Trichodesmium demonstrated strong CO₂ responses, which were attributed to an...
