Short term interactions between tree foliage and the aerial environment: An overview of modelling approaches available for tree structure-function models

Abstract: -Functional-structural tree models represent tree/aboveground environment interactions. Actually, plant architecture and function induce large variations in environmental variables within the canopy, while these variations themselves induce a range of responses at the organ scale which modulate plant function and architecture dynamics. This paper gives an overview of (i) processes involved in the short-term interactions between the tree foliage and the aboveground environment and (ii) associated modelling appr… Show more

“…Also, xylem embolism in Quercus ilex in mid-summer has been found to be much lower in trunks than in minor branches and twigs [34]; thus, leaves, twigs and minor branches experience higher strain under water stress conditions than do major branches and trunks. In addition, the more compact and closed crown provided by this treatment may reduce wind speed and light exposure of leaves inside the crown, all of which facilitates retention of water within the plant [28,38]. Accordingly, it is unadvisable to alter (open) the natural structure of the crown, at least at such low densities.…”

“…We used a Jarvis-type approach, assuming that leaf conductance is affected by non-synergistic interactions between plant and environmental variables [14,46]. Specific model parameters were derived for each shoot age class and canopy level.…”

“…Numerous surrogate methods to estimate understory solar radiation transmittance have been proposed, including empirical or process-based forest light models [56]. Empirical models relate light behavior to canopy or tree characteristics such as stand density, crown closure percentage, site index [32,35], basal area (e.g.…”
