  • Mineral assessment of open range livestock production on the Warm Springs Indian Reservation

    Creator:
    Brummer, Fara Ann
    Abstract:
    The Warm Springs Reservation is located in central Oregon. Livestock production consists of beef (commercial with an Angus, Horned Hereford base) and roping (Corriente and Longhorn) cattle and horses that forage most of the year on the open range within reservation boundaries. Forage consists of annual and perennial grasses and...

  • Evaluation of Topography and Seismicity on Shallow Landslide Susceptibility

    Creator:
    Hess, Daniel M.
    Abstract:
    Shallow landslides are a prevalent concern in mountainous regions that can result in severe societal, economic, and environmental impacts. The challenge is further compounded as the size and location of a potential slide is often unknown. This study presents a generalized approach for the evaluation of shallow landslide susceptibility using...

  • Trends in streamflow from old growth forested watersheds in the western Cascades

    Creator:
    Moore, Kathleen M.
    Abstract:
    Increasing temperatures in western North America are expected to result in a decline in winter snowpacks, earlier snowmelt, and a shift in the timing of streamflows, with an increasing fraction of streamflows occurring earlier in the water year and drier conditions during the summer. However, few streamflow datasets have associated...

  • The Influence of Glacial Isostatic Adjustment on Marine Stratigraphic Correlation

    Creator:
    King, Meghan E.
    Abstract:
    Glacial isostatic adjustment (GIA) alters the amplitude and timing of ‘glacioeustatic’ sea level maxima and minima around the globe. No study has examined the intrinsic distance that one can correlate marine stratigraphic records of glacial–interglacial sedimentation across continental shelves subject to varying amounts of GIA. Here, we seek to model...

  • Uplift capacity and displacement of helical anchors in cohesive soil

    Creator:
    Young, Jessica
    Abstract:
    Helical anchors are a type of deep foundation element that can be installed quickly in almost any location and can accept the immediate application of operational loads. The use of helical anchors has expanded in recent decades from its established application in the power transmission industry to more traditional civil...

  • Genomics-enabled exploration of insect toxicity in the Pseudomonas fluorescens group

    Creator:
    Rangel, Lorena I.
    Abstract:
    Pseudomonas is a diverse genus of Gamma proteobacteria that are ubiquitous in the natural environment, including soil, water, plant surfaces, and animals. The Pseudomonas fluorescens group is a diverse collection of seven subgroups and more than 50 named species. This group is known for their production of a variety of...

  • Identification of the plasminogen activator inhibitor produced by the day 14 bovine embryo

    Creator:
    Mendoza, Ruben
    Abstract:
    Day 12-14 bovine embryos produce urokinase-type plasminogen activator (uPA) and an uPA-plasminogen activator inhibitor (PAI) complex. The type of PAI, -1 or -2, in the complex has not been determined therefore the objective of this research was to identify the PAI produced by the Day 14 bovine embryo. In experiment...

  • Community profiles of ammonia oxidizers across high-elevation forest-to-meadow transects

    Creator:
    Mintie, Ann
    Abstract:
    In recent years considerable interest has been shown in the diversity of ammonia-oxidizing bacteria in soil communities. The majority of the research has been carried out in Northern Europe where soils have received high atmospheric inputs of nitrogen over the past two centuries. In contrast, although much work has been...

  • Non-linear nitrogen dynamics and calcium depletion along a temperate forest soil nitrogen gradient

    Creator:
    Sinkhorn, Emily R.
    Abstract:
    Understanding how N availability influences base cation stores is critical for long-term ecosystem sustainability. Indices of nitrogen (N) availability and the distribution of nutrients in plant biomass, soil, and soil water were examined across ten young, unpolluted Douglas-fir (Pseudotsuga menziesii) stands in the Oregon Coast Range spanning a three-fold soil...
