“…Several studies have recently shown an impact of ocean acidification with or without warming on the MgCO 3 /CaCO 3 ratio of coralline algae (e.g. Ries 2011, Egilsdottir et al 2013, DiazPulido et al 2014. Our data suggest that the response to these drivers could be modulated by irradiance, and that future experiments should cover the range of irradiance to which the coralline algae are exposed in the field.…”

“…For example, Egilsdottir et al (2013) demonstrated an average reduction of 0.013 mol% Mg/Ca in new structures formed by E. elongata in acidified conditions. This represents approximately 39% of the annual Mg variation experienced by present-day UK Corallina populations, of a similar magnitude to the increase projected with + 3°C SST.…”

Marine species depositing high-magnesium (Mg) calcite (> 8% MgCO 3 ) are projected to be among the first to show response to the impacts of climate change, i.e. increased sea surface temperature (SST) and ocean acidification (OA), given the increasing solubility of calcite in seawater with increasing Mg content. Temperature is a major driver of Mg incorporation into the skeletons of calcifying macroalgae, and thus climate change may induce deposition of more ), than other temperate calcifying macroalgae studied to date. Over the period 1850−2010, no change in the magnitude of Mg incorporation by C. officinalis was detected in herbarium samples. However, the strong relationship between SST and Mg content indicates that projected increases in SST by 2100, which are far greater than temperature increases that occurred between 1850−2010, could have substantial impact on geniculate coralline algae skeletal mineralogy, and must be considered synergistically with the effects of OA.

“…While many studies have pointed out that OA may have negative effects on macroalgae (Mercado et al 1999, Riebesell et al 2000, Zondervan et al 2001, Hall-Spencer et al 2008, Kuffner et al 2008, Gao & Zheng 2010, Sinutok et al 2011, Johnson et al 2012), a few found no effects (Israel & Hophy 2002, Egilsdottir et al 2013) and others even found in creases in photosynthesis, growth and calcification rates (Gao et al 1993, Kübler et al 1999, Zou 2005, Iglesias-Rodríguez et al 2008, Zou & Gao 2009, Roleda et al 2012. Many factors may be involved in the discrepancies among results, such as morpho-functional traits, the form of C acquisition, species adaptation/ acclimation to environmental con ditions, pre-experimental conditions and other methodological aspects (Ries et al 2009, Olabarria et al 2013).…”

Previous studies of the impact of increased CO 2 on macroalgae have mainly been done in laboratories or mesocosm systems, placing organisms under both artificial light and seawater conditions. In this study, macroalgae were incubated in situ in UV-transparent cylinders under conditions similar to the external environment. This system was tested in a short-term study (5.5 h incubation) on the effect of 2 partial pressures of CO 2 (pCO 2 ): air (ambient CO 2 ) and the pCO 2 predicted by the end of the 21st century (700 µatm, high CO 2 ), on photosynthesis, photosynthetic pigments and photoprotection in calcifying (Ellisolandia elongata and Padina pavonica) and non-calcifying (Cystoseira tamariscifolia) macroalgae. The calcifying P. pavonica showed higher net photosynthesis under high CO 2 than under ambient CO 2 conditions, whereas the opposite occurred in C. tamariscifolia. Both brown algae (P. pavonica and C. tamariscifolia) showed activation of non-photochemical quenching mechanisms under high CO 2 conditions. However, in P. pavonica the phenol content was reduced after CO 2 enrichment. In contrast to phenols, in E. elongata other photoprotectors such as zeaxanthin and palythine (mycosporine-like amino acid) tended to increase in the high CO 2 treatment. The different responses of these species to elevated pCO 2 may be due to anatomical and physiological differences and could represent a shift in their relative dominance as key species in the face of ocean acidification (OA). More in situ studies could be carried out to evaluate how macroalgae will respond to increases in pCO 2 in a future OA scenario. The in situ incubator system proposed in this work may contribute towards increasing this knowledge.
