SummaryCO2-and O2-exchange characteristics and δ13C values have been measured in a rhodophycean haptophyte (Lemanea mamillosa), a chlorophycean haptophyte (Cladophora glomerata) and a magnoliophyte rhizophyte (Ranunculus sp.) from a 5 m stretch of the Dichty Burn near Dundee. Light-and CO2-saturated rates of photosynthesis are greatest on a dry weight basis for Cladophora and lowest for Lemanea; the order is reversed on a surface area basis. The CO2 concentration at pH 6.5 at which… 
Carbon acquisition characteristics of six microalgal species isolated from a subtropical reservoir: potential implications for species succession
TLDR
This study investigated the acquisition of dissolved inorganic carbon by six species of microalgae, a cyanobacterium Cylindrospermopsis raciborskii, the diatoms Cyclotella sp.
UPTAKE OF INORGANIC CARBON BY CLADOPHORA GLOMERATA (CHLOROPHYTA) FROM THE BALTIC SEA1
TLDR
The inducibility of carbon uptake in C. glomerata may partly explain why this species is so successful in the upper littoral zone of the Baltic Sea, and it is shown that the proton pump can be induced by carbon limitation.
Inorganic carbon acquisition by eight species of Caulerpa (Caulerpaceae, Chlorophyta)
TLDR
The data suggest that the pyrenoid-containing C. cactoides and C. geminata, and probably C. scalpelliformis (which lacks pyrenoids) have CCMs, and the three species showing evidence of CCMs have the lowest affinities for inorganic C of the eight species tested.
Photosynthetic gas exchange under emersed conditions in eulittoral and normally submersed members of the Fucales and the Laminariales: interpretation in relation to C isotope ratio and N and water use efficiency
TLDR
Gas exchange data show that the Fucaceae exhibit more C4-like characteristics of their photosynthesis physiology than do the other five species tested, although even the Laminariales and Halidrys siliquosa are not classic C3 plants in their photosynthetic physiology.
Photosynthetic pathways in the Bromeliaceae of Trinidad: relations between life-forms, habitat preference and the occurrence of CAM
TLDR
The phylogenetic origins of CAM and the epiphytic habit in the Bromeliaceae is discussed and the influence of factors such as source CO2, photosynthetic photon flux density and ambient humidity in determining the δ13C values is discussed.
Carbon isotope fractionation in karst aquatic mosses
TLDR
A positive correlation between a14Cmoss and δ 13CMoss was observed for all data reflecting the change of carbon isotopic composition in DIC along the water flows and in atmospheric CO2 regardless of the climatic regions and historic period.
IMPACT OF TAXONOMY, GEOGRAPHY, AND DEPTH ON δ13C AND δ15N VARIATION IN A LARGE COLLECTION OF MACROALGAE 1
TLDR
The results suggest that the δ13C values were mostly determined by taxonomy, and parallel measurements of δ15N are more difficult to interpret mechanistically; there are no robust phylogenetic and large‐scale biogeographic correlations.
Freshwater angiosperm carbon concentrating mechanisms: processes and patterns.
TLDR
The structural, morphological, physiological, and biochemical features of freshwater macrophytes in the context of maximising net carbon uptake underwater are reviewed, and how inorganic carbon may influence macrophyte ecology is discussed.

Carbon dioxide as the exogenous inorganic carbon source for Batrachospermum and Lemanea
TLDR
The absence of HCO3 - use is discussed in relation to the “bipolar band growth” of florideophytes, and to the relative availability of C, N and P and light in these haptophytic algae.
Photosynthesis in the Aquatic Macrophyte Egeria densa. III. Gas Exchange Studies
TLDR
Closed and open circuit gas exchange experiments demonstrated that bicarbonate is taken up by the plant cells and does not act merely as a reservoir of inorganic carbon for production of CO2 at the plasmalemma.
THE DIFFERENTIAL ABILITY OF AQUATIC PLANTS TO UTILIZE THE INORGANIC CARBON SUPPLY IN FRESH WATERS
TLDR
It is concluded that a gradation exists, use depending on H CO3− as affected by alkalinity and pH of the bathing solution, and on the species' HCO3-compensation point, which is essential in characterizing the response of aquatic plants to inorganic carbon supply.
C4 characteristics of photosynthesis in the C3 alga Hydrodictyon africanum
TLDR
The chlorophyte type of ‘C02 concentrating mechanism’ appears to be common in other classes of eukaryotic algae, and in cyanophytes, while some ‘primitive’ charophytes may retain the mechanism which their ancestors presumably possessed.
Dark CO2-fixation and diurnal malic acid fluctuations in the submerged-aquatic Isoetes storkii
TLDR
It is suggested that CAM metabolism in this aquatic species may be related to the low availability of CO2 for photosynthesis during the day in its aquatic environment and that this metabolic pathway may prove common in the genus Isoetes.
ISOETES HOWELLII: A SUBMERGED AQUATIC CAM PLANT?'
TLDR
In the leaves (but not corms) of the submerged aquatic plant Isoetes howellii, malic acid concentration fluctuates from 1-3 mg g-1FW in the evening to 7-13 mg g/day in the morning, suggesting that CAM metabolism in this aquatic species may be related to the lower availability of CO2 for photosynthesis during the day than during the night in its aquatic environment.
The effects of carbon dioxide on the growth and development of amphibious plants
TLDR
Results are similar to those obtained previously with Marsilea, but concentrations of free CO2 higher than those in air may be essential for the normal growth and development of submerged amphibious plants.
Photosynthesis in the Aquatic Macrophyte Egeria densa. II. Effects of Inorganic Carbon Conditions on 14C Fixation
TLDR
Time courses of the distribution of photosynthetic intermediates indicated that the Calvin cycle remained the predominant pathway of carbon fixation, irrespective of the ambient conditions of TIC and pH, and the proportion of label found in malate increased.
TRANSPORT OF INORGANIC CARBON AND THE ‘CO2 CONCENTRATING MECHANISM’ IN CHLORELLA EMERSONII (CHLOROPHYCEAE) 1
TLDR
It is suggested that the site of active HCO3− transport in Chlorella (and other eukaryotes) is the chloroplast envelope, and the plasmalemma in cyanobacteria, which explains the obligatory role of the de‐repressed carbonic anhydrase in C4‐like photosynthesis in algae.
NUTRITIONAL STRATEGIES OF SUBMERGED BENTHIC PLANTS: THE ACQUISITION OF C, N AND P BY RHIZOPHYTES AND HAPTOPHYTES
TLDR
Evidence as to the sites of nutrient uptake on the surface of rhizophytes supports the view that a substantial fraction of phosphorus and nitrogen and, in some cases, inorganic carbon, is obtained from the sediment.
