  - 'While the significance of elevated atmospheric CO2 concentration on instantaneous
    leaf-level processes such as photosynthesis and transpiration is rarely disputed,
    its integrated effect at ecosystem level and at long-time scales remains a subject
    of debate. In part, the uncertainty stems from the inherent leaf-to-leaf variability
    in gas exchange rates. By combining 10 years of leaf gas exchange measurements
    collected during the Duke Forest Free Air CO2 Enrichment (FACE) experiment and
    three different leaf-scale stomatal conductance models, the leaf-to-leaf variability
    in photosynthetic and stomatal conductance properties is examined. How this variability
    is then reflected in ecosystem water vapor and carbon dioxide fluxes is explored
    by scaling up the leaf-level process to the canopy using model calculations. The
    main results are: (a) the space-time variability of the photosynthesis and stomatal
    conductance response is considerable as expected. (b) Variability of the calculated
    leaf level fluxes is dependent on both the meteorological drivers and differences
    in leaf age, position within the canopy, nitrogen and CO2 fertilization, which
    can be accommodated in model parameters. (c) Meteorological variability is playing
    the dominant role at short temporal scales while parameter variability is significant
    at longer temporal scales. (d) Leaf level results do not necessarily translate
    to similar ecosystem level responses due to indirect effects and other compensatory
    mechanisms related to long-term vegetation dynamics and ecosystem water balance.@eng'
