Effects of CO2 and their modulation by light in the life‐cycle stages of the coccolithophore Emiliania huxleyi (2012, background): “By the formation and export of organic carbon and CaCO3, these bloom-forming unicellular algae sustain vertical gradients of dissolved inorganic C (DIC) and alkalinity (Rost and Riebesell 2004).”
Ocean acidification: the other CO2 problem. (2009, background): “In contrast, the widely distributed coccolithophore E. huxleyi has low affinity for inorganic carbon and could be carbon limited in the modern ocean (Rost & Riebesell 2004).”
Poleward expansion of the coccolithophore Emiliania huxleyi (2014, background): “But diatoms (Giordano et al., 2005) and other coccolithophore species (Moolna and Rickaby, 2012) may be better adapted to low CO2 due to more efficient carbon acquisition than E. huxleyi (Rost and Riebesell, 2004).”
The biological pump in a high CO 2 world (2012, background): “…at present day pCO2 levels the photosynthetic carbon fixation rates of diatoms are close to their maximal rates (CO2 saturation at present day levels), whereas coccolithophores have a low affinity for inorganic carbon and appear carbon limited under present day conditions (Rost & Riebesell 2004).”
Effect of varying calcium concentrations and light intensities on calcification and photosynthesis in Emiliania huxleyi (2007, background): “The hypothesis that photosynthesis benefits from cal- cification by providing CO2 is still under debate (Rost and Riebesell 2004 and references therein).”
Emiliania huxleyi shows identical responses to elevated pCO2 in TA and DIC manipulations (2011, background): “huxleyi is usually capable to keep cell division rates constant over a wide range of conditions (Rost and Riebesell, 2004).”
Meta-analysis reveals negative yet variable effects of ocean acidification on marine organisms. (2010, background): “It is known that photosynthesis can stimulate calcification across numerous taxa (Borowitzka 1982; Gattuso et al. 1999, 2000; Rost & Riebesell 2004).”
Phytoplankton as Key Mediators of the Biological Carbon Pump: Their Responses to a Changing Climate (2018, background): “Continued acidification of surface seawater due to increased atmospheric CO2 levels changes the chemical conditions for biogenic calcification, although the outcome for different coccolithophore species is difficult to predict [38,56,57].”
Diversity and Ecology of Eukaryotic Marine Phytoplankton (2012, background): “Through the process of calcification and export of calcite to the deep ocean following cell death, coccolithophores play a key role in the "biological pump" that contributes significantly to global carbon cycling (Rost and Riebesell, 2004).”
Environmental controls on coccolithophore calcification (2012, background): “…increase in the mean PAR and UVR incident on photosynthetic organisms, as well as decreased fluxes of phosphate and of combined nitrogen (i.e. nitrogen other than N2) from the deep ocean to the surface (Rost & Riebesell 2004, Steinacher et al. 2010, Raven et al. 2011, 2012, Zeebe & Ridgwell 2011).”
Interactive effects of increased pCO2, temperature and irradiance on the marine coccolithophore Emiliania huxleyi (Prymnesiophyceae) (2008, background): “Previous work has suggested that a lower PIC/ POC ratio at higher pCO2 is mainly caused by a higher cellular POC quota, since photosynthesis is more sensitive than calcification to changes in CO2 concentration (Rost & Riebesell, 2004).”
