  text: The finite difference ecosystem-scale tree crown hydrodynamics model version
    2 (FETCH2) is a tree-scale hydrodynamic model of transpiration. The FETCH2 model
    employs a finite difference numerical methodology and a simplified single-beam
    conduit system to explicitly resolve xylem water potentials throughout the vertical
    extent of a tree. Empirical equations relate water potential within the stem to
    stomatal conductance of the leaves at each height throughout the crown. While
    highly simplified, this approach brings additional realism to the simulation of
    transpiration by linking stomatal responses to stem water potential rather than
    directly to soil moisture, as is currently the case in the majority of land surface
    models. FETCH2 accounts for plant hydraulic traits, such as the degree of anisohydric/isohydric
    response of stomata, maximal xylem conductivity, vertical distribution of leaf
    area, and maximal and minimal xylem water content. We used FETCH2 along with sap
    flow and eddy covariance data sets collected from a mixed plot of two genera (oak/pine)
    in Silas Little Experimental Forest, NJ, USA, to conduct an analysis of the intergeneric
    variation of hydraulic strategies and their effects on diurnal and seasonal transpiration
    dynamics. We define these strategies through the parameters that describe the
    genus level transpiration and xylem conductivity responses to changes in stem
    water potential. Our evaluation revealed that FETCH2 considerably improved the
    simulation of ecosystem transpiration and latent heat flux in comparison to more
    conventional models. A virtual experiment showed that the model was able to capture
    the effect of hydraulic strategies such as isohydric/anisohydric behavior on stomatal
    conductance under different soil-water availability conditions.
