  • 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...

  • Shrub epiphyte communities in relation to stand management in forests of western Oregon

    Creator:
    Rosso, Abbey L.
    Abstract:
    This dissertation describes the epiphyte communities on tall shrubs in forests of western Oregon, with a focus on potential effects of management practices on these communities. Shrubs and other hardwoods have recently gained recognition as hotspots of diversity for epiphytes in young conifer forests of the region. Yet little is...

  • Cellular and molecular aspects of cnidarian-algal associations

    Creator:
    Schwarz, Jodi A.
    Abstract:
    Intracellular symbioses between cnidarians and dinoflagellates from the genus Symbiodinium are widespread throughout the marine environment. These associations are ecologically significant, especially in tropical waters where symbiotic interactions between corals and Symbiodinium culminate in the formation of limestone reefs. This thesis focuses on cellular and molecular aspects of the symbiosis,...

  • Host associations of Tricholoma magnivelare, the American matsutake

    Creator:
    Lefevre, Charles K.
    Abstract:
    Beginning in the 1980s, large-scale commercial harvest of Tricholoma magnivelare created a need for management of forests to ensure sustainability, but little was known of the biology or ecology of this species to guide management decisions. Four of the five studies presented here explore the basic synecology of T. magnivelare...

  • Evolution and classification of bibionidae (Diptera: Bibionomorpha)

    Creator:
    Fitzgerald, Scott J.
    Abstract:
    The family Bibionidae has a worldwide distribution and includes approximately 700 species in eight extant genera. Recent studies have not produced compelling evidence supporting Bibionidae as a monophyletic group or identified the sister group to bibionids. Therefore, the purpose of this study is to examine the classification and evolution of...
