Do skeletal Mg/Ca ratios of Arctic rhodoliths reflect atmospheric CO2 concentrations?
Abstract The rhodolith-forming coralline red algal species Lithothamnion glaciale is the key ecosystem engineer of rhodolith beds on the coast of Svalbard. Because it significantly increases local biodiversity in this high-Arctic environment, we investigate the potential impact of changing environme...
