  • The influence of canopy structure and epiphytes on the hydrology of Douglas-fir forests

    Creator:
    Pypker, Thomas G.
    Abstract:
    Canopy structure has a significant impact on the canopy hydrology of Douglas-fir forests in the Pacific Northwest (PNW). Whole canopy rainfall interception was measured for young Douglas-fir forest and compared to an old-growth Douglas-fir forest. The old-growth forest had significantly greater canopy water storage capacity (5) and direct throughfall fraction...

  • Size-related variation in tree growth and physiology

    Creator:
    McDowell, Nate G.
    Abstract:
    The goal of this dissertation was to improve our understanding of age-related constraints on aboveground production of forest trees. Previous research suggesting that carbon uptake of old trees is hydraulically constrained by tree size was used as the springboard for this research. Three specific working hypotheses were investigated: 1) compensation...

  • Impact of exotic Ponderosa pine (Pinus ponderosa Doug. ex Laws.) plantations on water resources in northwestern Patagonia, Argentina

    Creator:
    Licata, Julian A.
    Abstract:
    Exotic ponderosa pine (Pinus ponderosa Doug. ex Lawson) plantations are being planted within the natural distribution area of cordilleran cypress (Austrocedrus chilensis (D.Don) Pic. Ser. et Bizzarri) in Patagonia, Argentina. The productivity of these exotic plantations is much greater than that of native forests, suggesting greater water use. Before these...
