• Coccolithophores and the biological pump: responses to environmental changes (2004, background): “In essence, if supply of CO2 for photosynthesis is indeed a primary role of calcification, this mechanism is rather inefficient when compared to CO2 concentrating mechanisms of non-calcifying phytoplankton such as diatoms and Phaeocystis (Burkhardt et al. 2001; Rost et al. 2003).”
• Primary production during nutrient-induced blooms at elevated CO2 concentrations (2009, background): “For the two diatoms Thalassiosira weissflogii and Phaeodactylum tricornutum, Burkhardt et al. (2001) showed that photosynthesis was unaffected by pCO 2 levels ranging from 36 to 1800 ppmv CO 2 , but the uptake of HCO − 3 was more important as source of inorganic C at low CO 2 levels than at high.”
• Responses of marine benthic microalgae to elevated CO2 (2011, unknown): “…relatively insensitive to changes in pH (Hinga 2002), and some oceanic diatoms show little response over a large CO 2 range (Tortell et al. 1997; Burkhardt et al. 2001), although other experiments haveshownpositiveresponsesofdiatoms toCO 2 enrichment (Riebesell et al. 1993; Burkhardt and…”
• A comparison of future increased CO2 and temperature effects on sympatric Heterosigma akashiwo and Prorocentrum minimum (2008, background): “Laboratory studies have shown that altered CO2 can result in species-specific changes in cellular carbon acquisition pathways (Raven, 1997; Tortell et al., 2000; Burkhardt et al., 2001) and elemental ratios (Burkhardt et al.”
• The effect of pCO2 on carbon acquisition and intracellular assimilation in four marine diatoms (2009, methodology): “Photosynthetic O 2 evolution as well as CO 2 and HCO 3 − uptake were quantified during steady-state photosynthesis by means of a membrane-inlet mass spectrometry (MIMS).”
• Ocean Acidification and Its Potential Effects on Marine Ecosystems (2008, background): “…rates when grown under high pCO2 conditions equivalent to ca. 760 micro atmosphere (µatm) (Tortell et al. 1997; Hein & Sand-Jensen 1997; Burkhardt et al. 2001; Tortell and Morel 2002; Rost et al. 2003; Beardall & Raven 2004; Schippers et al. 2004; Giordano et al. 2005; Martin &…”
• Testing the direct effect of CO2 concentration on a bloom of the coccolithophorid Emiliania huxleyi in mesocosm experiments (2005, background): “Moreover, recent studies demonstrated that phytoplankton species and functional groups differ regarding the efficiency and regulation of their CCMs, indicating that changes in CO2 availability might affect competition and succession of phytoplankton species (Burkhardt et al. 2001; Rost et al. 2003).”
• Effects of increased atmospheric CO 2 on small and intermediate sized osmotrophs during a nutrient induced phytoplankton bloom (2007, background): “…benefit, in terms of increased photosynthetic carbon fixation rates, from an15 increase in CO2 concentrations compared to the present day level (Riebesell et al., 2000; Rost et al., 2003) whereas others do not (P. pouchetii, several diatom species; Burkhardt et al., 1999, 2001; Rost et al., 2003).”
• Effect of ocean acidification on microbial diversity and on microbe-driven biogeochemistry and ecosystem functioning (2010, background): “It is reasonable to assume that increased CO2 availability will reduce the need for CCM activity and hence reduces the allocation of energy or nutrients for carbon acquisition (Burkhardt et al. 2001, Beardall & Giordano 2002).”
• Ocean acidification: the other CO2 problem. (2009, background): “…show little or no change in photosynthetic rates when grown under high pCO2 conditions equivalent to ~760 μatm (Tortell et al. 1997, Hein & SandJensen 1997, Burkhardt et al. 2001, Tortell & Morell 2002, Rost et al. 2003, Beardall & Raven 2004, Giordano et al. 2005, Martin & Tortell 2006).”
• How do marine diatoms fix 10 billion tonnes of inorganic carbon per year (2005, background): “HCO3 – becomes an increasing fraction of the total inorganic carbon uptake, as the CO2 concentration for growth is decreased (Burkhardt et al. 2001; Matsuda et al. 2001; Rost et al. 2003).”
• Ocean acidification enhances the growth rate of larger diatoms (2014, background): “…since availability of silicate is not directly affected by OA; however, growing evidence suggests that OA may alter silicification (Milligan et al. 2004; Herve et al. 2012), growth rates, elemental composition, and productivity of marine diatoms (Burkhardt et al. 1999, 2001; Tortell et al. 2008).”
