Climate change and ocean acidification effects on seagrasses and marine macroalgae (2013, background): “While seagrasses can raise XCaCO3 during the day, their leaves, along with highly organic sediments, have high respiratory demands, particularly under coastal eutrophication, which can depress pH at night to values (7.8; Semesi et al., 2009b) that would promote dissolution.”
Macroalgae may mitigate ocean acidification effects on mussel calcification by increasing pH and its fluctuations (2018, background): “Semesi et al. (2009) demonstrated for the calcifying algae Hydrolithon sp., Mesophyllum sp. and Halimedarenschii sp. that calcification was favored by the vicinity of seagrass driving substantial diurnal pH fluctuations with amplitudes of up to 1 pH unit.”
Can macroalgae contribute to blue carbon? An Australian perspective (2015, background): “Indeed, seagrass photosynthesis can promote calcification rates by other organisms, such as Halimeda, growing in seagrass beds (Semesi et al. 2009).”
Tropical seagrass meadows modify seawater carbon chemistry: implications for coral reefs impacted by ocean acidification (2012, background): “This is a process demonstrated at the micro-scale within small mesocosms but not yet at a habitat scale [17–19].”
Mangrove and Seagrass Beds Provide Different Biogeochemical Services for Corals Threatened by Climate Change (2016, background): “…that the variability in carbonate 511 chemistry of seagrass habitats is tightly coupled with the local cover of photoautotrophs (field 512 studies: Manzello et al., 2012; Hendriks et al., 2014; modelling: Unsworth et al., 2012; 513 laboratory analysis: Semesi et al., 2009b; Anthony et al., 2011).”
Biological mechanisms supporting adaptation to ocean acidification in coastal ecosystems (2015, unknown): “…57 58 59 60 61 62 63 64 Adaptation to OA impacts by biological mechanisms 8 seagrass photosynthesis enhanced calcification rates of calcareous red macroalgae (Hydrolithon sp. and Mesophyllum sp.) and the green macroalga Halimeda renschii growing within a tropical seagrass bed (Semesi et al., 2009).”
How good are we at assessing the impact of ocean acidification in coastal systems? Limitations, omissions and strengths of commonly used experimental approaches with special emphasis on the neglected role of fluctuations (2016, unknown): “(Yates et al. 2007; Semesi et al. 2009).”
Expansion of vegetated coastal ecosystems in the future Arctic (2014, background): “Hence, submerged macrophyte vegetation may serve an additional climate change mitigation role in the arctic coastal ecosystems by raising pH levels during periods of intense photosynthesis (Hendriks et al., 2014), thereby providing local refuge for calcifying organisms (Semesi et al., 2009).”
Concentration boundary layers around complex assemblages of macroalgae: Implications for the effects of ocean acidification on understory coralline algae (2013, background): “Metabolically driven fluctuating pH regimes around coastal organisms could also play a more important role than OA, or could interact with OA, in influencing the degree of dissolution of calcifying organisms in nearshore environments (Semesi et al. 2009a).”
