Combined effects of global climate change and nutrient enrichment on the physiology of three temperate maerl species
Abstract Made up of calcareous coralline algae, maerl beds play a major role as ecosystem engineers in coastal areas throughout the world. They undergo strong anthropogenic pressures, which may threaten their survival. The aim of this study was to gain insight into the future of maerl beds in the co...

Abstract Made up of calcareous coralline algae, maerl beds play a major role as ecosystem engineers in coastal areas throughout the world.

We examined the effects of rising temperatures (+3°C) and ocean acidification (−0.3 pH units) according to temperature and pH projections (i.e., the RCP 8.5 scenario), and nutrient (N and P) availability on three temperate maerl species ( Lithothamnion corallioides , Phymatolithon calcareum , and Lithophyllum incrustans ) in the laboratory in winter and summer conditions.
