Little is known about the combined impacts of future CO2 and temperature increases on the growth and physiology of marine picocyanobacteria. We incubated Synechococcus and Prochlorococcus under present‐day (380 ppm) or predicted year‐2100 CO2 levels (750 ppm), and under normal versus elevated temperatures (+4°C) in semicontinuous cultures. Increased temperature stimulated the cell division rates of Synechococcus but not Prochlorococcus. Doubled CO2 combined with elevated temperature increased… Expand
Effects of elevated CO2 and nitrogen supply on the growth and photosynthetic physiology of a marine cyanobacterium, Synechococcus sp. PCC7002
TLDR
It is indicated that elevated CO2 and N-supply interacted to alter the physiology and cellular biochemistry of Synechococcus sp. Expand
Do increased temperature and CO2 levels affect the growth, photosynthesis, and respiration of the marine macroalga Pyropia haitanensis (Rhodophyta)? An experimental study
TLDR
It is proposed that the growth of P. haitanensis would not be stimulated by the ongoing climate change (increasing atmospheric CO2 and global warming) and that elevated temperature exerted a greater pronounced effect on carbon metabolism than elevated CO2 did. Expand
Effects of elevated CO2 and temperature on the growth, elemental composition, and cell size of two marine diatoms: potential implications of global climate change
TLDR
The results indicated that both the cell-specific growth rates and the carrying capacity of A. coffeaeformis decreased at the higher temperature treatment, whereas N. ovalis did not differ among all treatments, and no significant difference was found in either species’ elemental cell composition. Expand
Interactive effects of increased pCO2, temperature and irradiance on the marine coccolithophore Emiliania huxleyi (Prymnesiophyceae)
TLDR
The results suggest that future trends of CO2 enrichment, sea-surface warming and exposure to higher mean irradiances from intensified stratification will have a large influence on the growth of Emiliania huxleyi, and potentially on the PIC/POC ‘rain ratio’. Expand
Effect of Temperature on Photosynthesis and Growth in Marine Synechococcus spp.1[C][OPEN]
Marine Synechococcus regulates state transitions and photosynthetic protein content for temperature acclimation. In this study, we develop a mechanistic understanding of how temperature affectsExpand
Effects of elevated pCO2 on physiological performance of marine microalgae Dunaliella salina (Chlorophyta, Chlorophyceae
TLDR
The results show that photosynthesis, dark respiration and CCMs will be affected by the increased pCO2/low pH conditions predicted for the future, but that the responses of D. salina to high p CO2/ low pH might be modulated by other environmental factors such as light, nutrients and temperature. Expand
Responses of elevated CO2 on photosynthesis and nitrogen metabolism in Ulva lactuca (Chlorophyta) at different temperature levels
TLDR
The results suggest that the responses to elevated CO2 in U. lactuca were temperature-dependent, and elevatedCO2 alone was less effective than temperature levels. Expand
A comparison of future increased CO2 and temperature effects on sympatric Heterosigma akashiwo and Prorocentrum minimum
TLDR
Growth and physiology of Heterosigma showed a much greater positive response to elevated CO2 and temperature compared to Prorocentrum, consistent with what is known about their respective carbon acquisition mechanisms. Expand
Increased pCO2 and temperature reveal ecotypic differences in growth and photosynthetic performance of temperate and Arctic populations of Saccharina latissima
TLDR
It is concluded that both populations differ in their sensitivity to changing temperatures and OA and that the Arctic population is more likely to benefit from the upcoming environmental scenario than its Atlantic counterpart. Expand
CO-CULTURE WITH SYNECHOCOCCUS FACILITATES GROWTH OF PROCHLOROCOCCUS UNDER OCEAN ACIDIFICATION CONDITIONS.
TLDR
It is shown that the exponential growth rates of these two genera respond to future CO2 conditions in a manner similar to other cyanobacteria, but Prochlorococcus strains had significantly lower realized growth rates under elevated CO2 regimes due to poor survival after exposure to fresh culture media.

Effects of CO2 concentrations on the freshwater microalgae, Chlamydomonas reinhardtii, Chlorella pyrenoidosa and Scenedesmus obliquus (Chlorophyta)
TLDR
It can be concluded that increased CO2 concentrations with decreased pH could affect the growth rate and photosynthetic physiology of C. reinhardtii, C. pyrenoidosa, and S. obliquus. Expand
INORGANIC CARBON REPLETION DISRUPTS PHOTOSYNTHETIC ACCLIMATION TO LOW TEMPERATURE IN THE CYANOBACTERIUM SYNECHOCOCCUS ELONGATUS 1
TLDR
23°C high Ci cells generated more reductant from PSII than could be accommodated by downstream assimilative metabolism, resulting in early senescence and death of 23°Chigh Ci cells, probably as a result of the generation of reactive byproducts of electron transport. Expand
Impacts of elevated CO2 concentration on biochemical composition, carbonic anhydrase, and nitrate reductase activity of freshwater green algae
TLDR
It can be concluded that CO2 enrichment can affect biochemical composition, CA, and nitrate reductase activity, and that the biochemical response was species dependent. Expand
