When iron is limited, the tiny algae that live within coral cells—which can provide the majority of a coral’s nutritional needs—change how they take in other trace metals, which could have cascading effects on vital biological functions. A new study in the journal Coral Reefs explores how different species of these microalgae rely on iron, whose already limited supply in oceans could decline with warming ocean waters, perhaps exacerbating the effects of climate change on corals.
