  • Douglas-fir Seedlings in the Pacific Northwest: The Genetics of Drought Adaptation

    Creator:
    Celer, Erda
    Abstract:
    Douglas-fir (Pseudotsuga menziesii) is a widely distributed, ecologically important, and commercially valuable tree species in North America. However, climate change is expected to adversely impact Douglas-fir trees, and assisted migration may become necessary to lessen the effects of climate change. Because drought stress is one of the projected effects of...

  • Identifying candidate genes associated with cold adaptation in Douglas-fir using DNA microarrays

    Creator:
    Howe, Dana Kathryn
    Abstract:
    In forest trees from temperate and boreal regions, cold acclimation is an important adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...

  • Climate-based Seed Deployment Zones for the Pacific Northwest

    Creator:
    McClure, Meridith L.
    Abstract:
    Native populations of forest trees are specifically adapted to the climates they inhabit. The farther trees are moved from their local climates (i.e., as the climatic transfer distance increases), the more growth and survival tend to decrease. The transfer limit is the climatic transfer distance beyond which plantation performance is...
