Calcification in free-living coralline algae is strongly influenced by morphology: implications for susceptibility to ocean acidification
Rhodolith beds built by free-living coralline algae are important ecosystems for marine biodiversity and carbonate production. Yet, our mechanistic understanding regarding rhodolith physiology and its drivers is still limited. Using three rhodolith species with different branching morphologies, we i...
