  author={Wendy E. Robe and Howard Griffiths},
The decline and disappearance of Littorella uniflora from oligotrophic waters which have become eutrophic has been associated with shading or reduced CO2 supply. However NOinf3sup−concentrations can reach very high levels (100–2000 mmol m−3 compared with <1–3 in oligotrophic habitats). To investigate the impact of NOinf3sup−loading alone, plants were grown under three NOinf3sup−regimes (very low, near-natural and high). The interactive effects of NOinf3sup−and photon flux density (low and high… 
The response of Vallisneria spinulosa (Hydrocharitaceae) to different loadings of ammonia and nitrate at moderate phosphorus concentration: a mesocosm approach
Nitrogen concentration had little influence on the growth of the eutrophication tolerant submerged macrophyte at moderately low concentrations of phosphorus, suggesting that loss of macrophytes observed in other studies, run at higher phosphorus concentrations, was probably related to enhanced shading by periphyton and/or phytoplankton rather than to any toxic effects of N.
Nutrient concentrations in a Littorella uniflora community at higher CO2 concentrations and reduced light intensities
SUMMARY 1. Oligotrophic softwater lakes represent a special type of aquatic ecosystem with unique plant communities where generalisations from other aquatic plant communities to rising CO2 in the
Effects of moderate ammonium enrichment on three submersed macrophytes under contrasting light availability
The results indicate that a moderate NH(4)(+) enrichment was not directly toxic to the macrophytes although it might change their viability in eutrophic lakes in terms of the carbon and nitrogen metabolism.
Possible positive-feedback mechanisms: plants change abiotic soil parameters in wet calcareous dune slacks
In this paper the results are presented from a mesocosm study of the effects of typical dune slack plants on the soil solution nutrient contents. In dune slack succession, early successional species
Effects of ammonium pulse on the growth of three submerged macrophytes
This study contributes to revealing the roles of NH4-N pulse on the growth of aquatic plants and its species specific effects on the dynamics of submerged macrophytes in lakes.
The role of NH+4 toxicity in the decline of the submersed macrophyte Vallisneria natans in lakes of the Yangtze River basin, China
It is indicated that NH4+ toxicity arising from eutrophication probably plays a key role in the deterioration of submersed macrophytes like V. natans in lakes of the Yangtze River basin.
Freshwater angiosperm carbon concentrating mechanisms: processes and patterns.
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.
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.
Changes in physico-chemical conditions and macrophyte abundance in a shallow soft-water lake mediated by a Great Cormorant roosting colony
This study examined the effects of the Great Cormorant ( Phalacrocorax carbo sinensis L.) roosting colony on the physico-chemical conditions and macrophyte abundance in a shallow soft-water lobelia


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.
C3 and CAM Photosynthetic Characteristics of the Submerged Aquatic Macrophyte Littorella uniflora: Regulation of Leaf Internal CO2 Supply in Response to Variation in Rooting Substrate Inorganic Carbon Concentration
Plants obtained from Esthwaite Water or a local reservoir were obtained, with the latter plants transplanted into a range of sediment types to alter C02 supply around the roots to evaluate diffusion limitation and select a suitable size for comparative studies of photosynthetic 02 evolution.
Photosynthesis of Littorella uniflora grown under two PAR regimes: C3 and CAM gas exchange and the regulation of internal CO2 and O2 concentrations
PAR rather than CO2 supply appeared to limit photosynthesis even in high PAR grown plants, and CAM appears to have an important role in the regulation ofCO2 supply for photosynthesis in response to variation in light regime.
Nitrogen nutrition and the level of Crassulacean acid metabolism in Kalanchoë lateritia Engl.
IRGA determination of CO2 nocturnal uptake showed that N/5 plants began CO2 capture earlier and at a more intense rate and for a longer period than plants from other groups also having a daily variation of titratable acidity indicative of performing strong CAM.
