| Water-use efficiency (WUE) has been recognized as an important characteristic of vegetation productivity in various natural scientific disciplines for decades, but only recently at the ecosystem level, where different ways exist to characterize water-use efficiency. 5 Hence, the objective of this research was (a) to systematically compare different ways of calculating ecosystem water-use efficiency (WUEe) from eddy-covariance measurements, (b) quantify the diurnal, seasonal and interannual variability of WUEe in relation to meteorological conditions, and (c) analyse between-site variability of WUEe as affected by vegetation type and climatic conditions, across sites in European forest 10 ecosystems. Day-to-day variability of gross primary productivity... |

| Studying the water transport in the soil-plant system requires information on the spatio-temporal variability of both subsystems and the ability to assess the impact of the soil heterogeneity and of the biological responses on the coupling between vegetation and its substrate. This study was conducted for 2 years in a vineyard in the Aude Valley, France, by measuring the particle size distribution of the topsoil, the instantaneous isotopic ratios (18O/16O, 2H/1H) of leaf water, annual shoot biomass production, and interannual persistence of this biomass along a 360 m transect. The resultant spatial series were analysed for their correlations and converted to spectra. Changes in the isotopic ratios along the transect reflect the soil texture gradient,... |

| Background and Aims: Leaf responses to environmental conditions have been frequently described in fruit trees, but differences among cultivars have received little attention. This study shows that parameters of Farquhar’s photosynthesis and Jarvis’ stomatal conductance models differed between two apple cultivars, and examines the consequences of these differences for leaf water use efficiency.† Methods :Leaf stomatal conductance (gsw), net CO2 assimilation rate (An), respiration (Rd) and transpiration (E) were measured during summer in 8-year-old ‘Braeburn’ and ‘Fuji’ apple trees under well-watered field conditions. Parameters of Farquhar’s and Jarvis’ models were estimated, evaluated and then compared between cultivars. Leaf carbon isotope discrimination... |
