  • Ecology of Corydalis aquae-gelidae, a rare riparian plant

    Creator:
    Goldenberg, Douglas M.
    Abstract:
    Corydalis aquae-gelidae is a large herbaceous perennial in the Fumariaceae that has high habitat specificity. It is endemic to the western Cascade Range of Oregon and Washington, almost entirely on the Mt. Hood and Gifford Pinchot National Forests. It is a federal C2 candidate under the Endangered Species Act and...

  • Ecophysiology of the cyanolichen Lobaria oregana

    Creator:
    Antoine, Marie E.
    Abstract:
    This thesis consists of three manuscripts describing ecophysiological research on the cyanolichen Lobaria oregana. The first manuscript includes a re-evaluation of the assumptions underlying past estimates of N fixation by this species and provides an estimate of annual N fixation at the Wind River Canopy Crane (WRCC). Based upon litterfall...

  • Castilleja and Pedicularis are confirmed as telial hosts for white pine blister rust in whitebark pine ecosystems of Oregon and Washington

    Creator:
    Mulvey, Robin L.
    Abstract:
    The primary objective of this research was to determine if native species within the genera Castilleja and Pedicularis are naturally infected by white pine blister rust (Cronartium ribicola) in whitebark pine ecosystems of the Oregon and Washington Cascade Range. Secondary objectives were to monitor the phenology of aecial and telial...

  • Systematics of the genus Otidea in the Pacific Northwest

    Creator:
    Peterson, Eric T.
    Abstract:
    The fungal ascomycete genus Otidea as represented in the Pacific Northwest of North America includes eight well known species and two poorly-known species. Cladistic analysis utilizing characters from ribosomal DNA and morphology allowed the development of a robust phylogenetic species concept for Otidea. The combination of characters from the ribosomal...
