  • Relative competitive abilities of several common forest species and planted Douglas-fir in western Oregon

    Creator:
    Naylor-Murphy, Lanea
    Abstract:
    In terms of production forestry, more often than not any species that is not the crop species is considered a competitor as they are using finite growing resources that would otherwise be available to the crop species. With specific regard to Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) production in the Pacific...

  • Tree Vigor Response and Competitive Zone Density in Mature Ponderosa Pine

    Creator:
    Shaw, Randi C.
    Abstract:
    This study explored the relationship of mature ponderosa pine (Pinus ponderosa Dougl. ex Laws) tree vigor and competitive zone density following thinning and fuel reduction treatments. Competitive zone density (CZD) was defined as the total tree basal area (m²/ha) surrounding a given ponderosa pine tree within a 10m fixed radius...

  • Defensible Space Development: Exploring The Role of Arborists in Wildfire Risk Mitigation for Communities of the Pacific Northwest

    Creator:
    Pritchett, Sylvan
    Abstract:
    Every year in North America homes in the Wildland-Urban interface (WUI) are destroyed by wildfires. The creation of defensible space around homes in the WUI, through the management of vegetation can help mitigate some of the risk posed by fire. While many homeowners recognize the need for defensible space around...

  • Exploring the constraints of the use and management of school forests in South Korea

    Creator:
    Hong, Hyun Jung
    Abstract:
    School forests in South Korea are trees and vegetation areas within schoolyards, and they provide natural environments for schools and neighborhoods. After the Korea Forest Service (KFS) and local governments create these school forests, the management of school forests transfers to the host schools. Some studies suggest that experiences with...

  • Suppression of yolk polypeptide gene expression in Drosophila melanogaster by sodium butyrate treatment

    Creator:
    Fairfax, Carolyn S.
    Abstract:
    Current evidence suggests that temporal regulation of gene expression in eucaryotic organisms relies primarily upon localized structural modifications of chromatin. One possible means of changing chromatin structure is through varying the level of acetylation of the histone proteins. Sodium butyrate has been found to inhibit the activity of histone deacetylase...

  • Shoreline changes due to jetty construction on the Oregon Coast

    Creator:
    Lizarraga Arciniega, Jose Roman
    Abstract:
    Patterns of beach erosion and accretion due to jetty construction are examined for the coast of Oregon. All jetty systems are included with the exception of those on the Columbia River, making a total of nine systems. All evidence indicates that these areas of the Oregon coast are experiencing a...

  • The Erosion of Siletz Spit, Oregon

    Creator:
    Rea, Campbell Cary
    Abstract:
    Siletz Bay is a drowned river valley filled with Holocene alluvial and estuarine sediments and is separated from the ocean by a sand spit 3.8 km in length. Since the area was settled by white man in the 1890's, the bay has apparently experienced rapid siltation, due to increased farming...

  • Breaking waves : a review of theory and measurements

    Creator:
    Gaughan, Michael Kenneth
    Abstract:
    Theoretical breaking criteria for progressive surface gravity waves are examined, and laboratory and field experiments concerned with breaking waves are reviewed with respect to the testing of these breaking criteria. The measurements of Komar and Simmons are presented here for the first time. Only three theoretical breaking criteria have been...

  • Beach profile changes and onshore-offshore sand transport on the Oregon coast

    Creator:
    Aguilar Tunon, Nicolas A.
    Abstract:
    Two beaches with significant differences in grain size and thus in beach profile morphology and response to wave conditions were studied on the Oregon coast. Gleneden Beach, just south of Siletz Spit and Lincoln City, has a median grain size of 0.36 mm (medium sand) and a steep beach face...

  • Sediment transport beneath an undular hydraulic jump

    Creator:
    Broome, Robert
    Abstract:
    Field observations are made of the formation of backwash ripples on the beachface, formed by undular hydraulic jumps generated by backwash down the beach face colliding with wave bores. Measured ripple wavelengths range from set averages of 48 to 70 cm. Within a particular set of ripples there is a...
