The seasonal temperature acclimation in crassulacean acid metabolism (CAM) and photosynthetic performance were investigated in the aquatic isoetid, Littorella uniflora. Plants were collected monthly from January to September, and CAM capacity and photosynthesis rates were measured at 5, 10, 15, and 20 °C. Seasonal acclimation was observed for CAM (Q10 range: 0.6–1.8), and CAM was optimised close to ambient temperature throughout the season. Thus, in winter acclimated L. uniflora, the short-term…

Trade-offs and Synergies in the Structural and Functional Characteristics of Leaves Photosynthesizing in Aquatic Environments
Aquatic plants, comprising different divisions of embryophytes, derive from terrestrial ancestors. They have evolved to live in water, both fresh and salty, an environment that presents unique
CO2 and O2 dynamics in leaves of aquatic plants with C3 or CAM photosynthesis – application of a novel CO2 microsensor
The deployment of the new CO2 microsensor to resolve questions related to plant aeration and the continuous measurements of pCO2 and pO2 highlighted the contrasting tissue gas compositions in submerged C3 and CAM plants.


Seasonal diurnal acid rhythms in two aquatic crassulacean acid metabolism plants
Comparing CAM activity for populations of the same species indicates that the magnitude of CAM activity is closely related to plant productivity, and appears to be related to light and perhaps CO2 availability.
Effects of seasonal changes in the Midwest on Crassulacean Acid Metabolism (CAM) in Opuntia humifusa Raf
Seasonal changes in the Crassulacean Acid Metabolism (CAM) activity and growth characteristics of Opuntia humifusa Raf were examined under midwest climatic conditions and acid fluctuations were minimal with CO2 being taken up during the day and released at night, indicating some degree of flexibility in the CAM activity.
Seasonal variation in the ecophysiology of Littorella uniflora (L.) Ascherson in acidic and eutrophic habitats
The environment was more favourable for plant growth at Esthwaite Water (the eutrophic site) than at Red Tarn (acidic) and the relationships between environmental conditions and plant performance at the two sites are discussed in the context of the disappearance of L. uniflora from acidic and eUTrophic sites in N. Europe in recent years.
Crassulacean acid metabolism contributes significantly to the in situ carbon budget in a population of the invasive aquatic macrophyte Crassula helmsii
Overall CAM activity increased from April to July, which is consistent with higher potential carbon limitation caused by increased temperature and light availability, and suggests that CAM is highly important for the whole population of C. helmsii.
The contribution of crassulacean acid metabolism to the annual productivity of two aquatic vascular plants
The results suggest that the contribution of CAM to annual productivity is greater for the less productive population of each species.
CAM photosynthesis in submerged aquatic plants
It is concluded that similar proportions of the aquatic and terrestrial floras have evolved CAM photosynthesis, and it is hypothesized that neotropical lacustrine species may be more ancient in origin and have given rise to terrestrial species, which have retained most of the characteristics of their aquatic ancestry.

Crassulacean acid metabolism in the seasonally submerged aquatic Isoetes howellii
Preliminary estimates suggest that under natural submerged conditions, early morning photosynthetic rates may be substantially higher than dark CO2 uptake rates, though uptake rates throughout much of the day could be substantially lower than nightime CO2 assimilation.
Light effects on crassulacean acid metabolism in the submerged aquatic plant Isoetes kirkii A. Braun
In situ shading experiments demonstrated that, at any one time, the diel acid fluctuations were controlled by the ambient light levels as the other variables were constant, and showed that there was a close relationship between photosynthetic rates and de‐acidification when related to light intensity.
