Calcification of the Arctic Coralline Red Algae Lithothamnion Glaciale in Response to Elevated CO2
Vol. 441: 79–87, 2011 MARINE ECOLOGY PROGRESS SERIES Published November 15 doi: 10.3354/meps09405 Mar Ecol Prog Ser OPENPEN ACCESSCCESS Calcification of the Arctic coralline red algae Lithothamnion glaciale in response to elevated CO2 Jan Büdenbender*, Ulf Riebesell, Armin Form Leibniz Institute of Marine Sciences (IFM-GEOMAR), University of Kiel, Düsternbrooker Weg 20, 24105 Kiel, Germany ABSTRACT: Rising atmospheric CO2 concentrations could cause a calcium carbonate subsatura- tion of Arctic surface waters in the next 20 yr, making these waters corrosive for calcareous organ- isms. It is presently unknown what effects this will have on Arctic calcifying organisms and the ecosystems of which they are integral components. So far, acidification effects on crustose coralline red algae (CCA) have only been studied in tropical and Mediterranean species. In this work, we investigated calcification rates of the CCA Lithothamnion glaciale collected in northwest Svalbard in laboratory experiments under future atmospheric CO2 concentrations. The algae were exposed to simulated Arctic summer and winter light conditions in 2 separate experiments at opti- mum growth temperatures. We found a significant negative effect of increased CO2 levels on the net calcification rates of L. glaciale in both experiments. Annual mean net dissolution of L. glaciale was estimated to start at an aragonite saturation state between 1.1 and 0.9 which is projected to occur in parts of the Arctic surface ocean between 2030 and 2050 if emissions follow ‘business as usual’ scenarios (SRES A2; IPCC 2007). The massive skeleton of CCA, which consist of more than 80% calcium carbonate, is considered crucial to withstanding natural stresses such as water move- ment, overgrowth or grazing. -

Molecular analyses including type material of P. lamii and P. laevigatum were congruent in delimiting P. lusitanicum as an independent lineage from these crustose species. The three species shared a common external morphology of multiporate asexual conceptacles, but P. lusitanicum has been detected only unattached as maerl while P. lamii and P. laevigatum are crustose. Phymatolithon lusitanicum is particularly abundant in subtidal maerl beds of the Atlantic Iberian Peninsula (Galicia and the Algarve); however it has also been detected northwards in Ireland intertidally and in Western Mediterranean Sea (Alborán Sea, Balearic Islands) down to 64 m. -

The status and generic disposition of Available online 7 December 2013 those species (L. acervatum, L. ferox, L. foveatum) have remained unresolved ever since Düwel and Wegeberg Edited by JC Manning (1996) determined from a study of relevant types and other specimens that Leptophytum Adey was a heterotypic synonym of Phymatolithon Foslie. Based on our study of numerous recently collected specimens and of published Keywords: data on the relevant types, we have concluded that each of the above species previously ascribed to Leptophytum Non-geniculate coralline algae represents a distinct species of Phymatolithon, and that four species (incl.
