“…Because of the long incubation time necessary to test the effect of this substance, pH-drift experiments are among the few experimental methods suitable (Choo et al 2002;Ray et al 2003). The major inhibition suggests that a P-type H + -ATPase (proton pump) was involved in carbon uptake in desmids.…”

Most likely, these active uptake mechanisms make use of H + -ATPase, as none of the desmids expressed significant carbonic anhydrase activity. A series of strains of Staurastrum planctonicum isolated from different habitats, all clustered in between the species using HCO 3 -, but no further differentiation was observed. Therefore, desmids cannot be simply characterized as exclusive CO 2 users, and the ecological distribution pattern of a desmid species does not unequivocally link to a certain C i uptake mechanism. Nevertheless, there does appear to be a general ecological link between a species' C i uptake mechanism and its ecological distribution.Key words: pH drift, desmids, isolate variation, inorganic carbon acquisition. -. Ces mécanismes d'absorption active utilisent vraisemblablement la H + -ATPase, puisqu'aucune des desmidiées ne montre une activité anhydrase carbonique significative. Un ensemble de souches du Staurastrum planctonicum, isolées de différents habitats, se regroupent toutes au sein des espèces utilisant le HCO 3 -, sans qu'on puisse observer d'autre différenciation. Consé-quemment, les desmidiées ne peuvent pas être simplement caractérisées comme utilisatrices exclusives de CO 2, , et le patron de distribution écologique d'une espèce de desmidiée n'est pas nécessairement lié à un certain mécanisme d'absorption du C i . Cependant, il ne semble pas exister un lien écologique général entre le mécanisme d'absorption du C i et sa distribution écologique.Mots clés : dérive du pH, desmidiées, variation des isolats, acquisition du carbone inorganique.[Traduit par la Rédaction] Spijkerman et al. 858

“…For calcareous Chara thaii, plant calcification competed for DIC with photosynthesis in mild-alkaline water (e.g. McConnaughey and Falk, 1991;Ray et al, 2003). So the increase of DIC utilization by photosynthesis would result in the decrease of available DIC for calcification.…”

In mildly alkaline water, DIC decreased by two means, either was taken up by the photosynthesis of the algae or became incorporated in the cell wall of Chara by calcification (Ray et al, 2003). However, lots of experiments studying bicarbonate utilization of Chara spp.…”

“…Thus, the C source utilized is species specific and appears to be inseparably related to the growth form of each species. Additional detailed field investigations of a range of species representing different growth forms and a range of conditions above, within and beneath a charophyte stand as well as laboratory testing the exact CO 2 acquisition for photosynthesis and membrane transport mechanisms (e.g., Ray et al, 2003;Beilby & Casanova, 2014), and respiration effects would explicitly verify our assumption. This is particularly important in the context of the aforementioned use of d 13 C values in palaeoecological studies as an indication of the source of matter in sediment deposits.…”

Sharp differences in the δ13C values of organic matter and carbonate encrustations but not in ambient water DIC between two morphologically distinct charophytes

The stable carbon isotope composition of the carbonate encrustations (d 13 C CARB ), organic matter (d 13 C ORG ) and the dissolved inorganic carbon (d 13 C DIC ) in the ambient lake waters were analysed for two common but morphologically different and, thus, representing different growth forms of Chara species. We hypothesized that the relationships between d 13 C CARB , d 13 C ORG and d 13 C DIC are species specific and related to the different growth forms of the studied charophytes. For each species (Chara tomentosa and Chara globularis), 10 individuals and water samples from above the macrophytes were collected in five lakes at three sites per lake in mid-summer. Opposing shifts were found between d 13 C CARB and d 13 C DIC values with 13 C enrichment in C. tomentosa and 13 C depletion in C. globularis. In addition, C. globularis exhibited more negative values of d 13 C ORG than C. tomentosa, even under similar conditions. The d 13 C CARB and d 13 C ORG values were positively correlated in both species, but d 13 C CARB and d 13 C DIC as well as d 13 C ORG and d 13 C DIC were positively correlated in C. tomentosa only. The differences found result from the different proportions between 13 C and 12 C in DIC used as a CO 2 source for photosynthesis, which is linked to the different growth forms represented by the two studied charophytes and, thus, are species specific as we hypothesized.
