Primary production, respiration and calcification of the temperate free-living coralline alga Lithothamnion corallioides [link]Paper  doi  abstract   bibtex   
Calcification and primary production responses to irradiance in the temperate coralline alga Lithothamnion corallioides were measured in summer 2004 and winter 2005 in the Bay of Brest. Coralline algae were incubated in dark and clear bottles exposed to different irradiances. Net primary production reached 1.5μmolCg−1drywth−1 in August and was twice as high as in January–February. Dark respiration showed significant seasonal variations, being three-fold higher in summer. Maximum calcification varied from 0.6μmolg−1drywth−1 in summer 2004 to 0.4μmolg−1drywth−1 in winter 2005. According to P–E curves and the daily course of irradiance, estimated daily net production and calcification reached 131μgCg−1drywt and 970μgCaCO3g−1drywt in summer 2004, and 36μgCg−1drywt and 336μgCaCO3g−1drywt in winter 2005. The net primary production of natural L. corallioides populations in shallow waters was estimated at 10–600gCm−2y−1, depending on depth and algal biomass. The mean annual calcification of L. corallioides populations varied from 300 to 3000gCaCO3m−2. These results are similar to those reported for tropical coralline algae in terms of carbon and carbonate productivity. Therefore, L. corallioides can be considered as a key element of carbon and carbonate cycles in the shallow coastal waters where they live.
