  • Timescales and tectonics of oceanic plateaus : long-term evolution of Ontong Java Nui and Rio Grande Rise

    Creator:
    Davidson, Peter C.
    Abstract:
    Oceanic plateaus are regions of overthickened oceanic crust and are often thought to form from the interaction of mantle plumes with oceanic lithosphere. These regions can cover vast areas of the ocean basins and represent a highly elevated magmatic flux relative to normal mid-ocean ridge spreading. Oceanic plateaus are considered...

  • Efficacy of Empirical Seed Zones: Pseudoroegneria Spicata Reproductive Phenology & Seedling Stage Traits

    Creator:
    Prive, Kathryn A.
    Abstract:
    Ecological restoration is needed to mitigate losses to biodiversity. Restoration success is enhanced through the use of native plant materials that are genetically diverse and locally adapted. Seed transfer zones have been developed to delineate geographic areas where native seed can be collected and distributed with reduced risk of maladaptation....

  • The Climate Change - Homelessness Nexus : how disaster response institutions reinforce structural vulnerability in wildfire-impacted communities in Oregon

    Creator:
    Werdel, Carly Inez
    Abstract:
    In communities impacted by climate disasters, institutions largely determine the distribution of outcomes within a population. This research aims to examine the role of institutions in differential outcomes for displaced communities impacted by the 2020 Labor Day Wildfires in the Santiam Canyon and the Rogue Valley. Using semi-structured interviews of...

  • Grassland Restoration and Climate Change: Altar Valley, Arizona Case Study

    Creator:
    Gondor, Anne
    Abstract:
    The Altar Valley is an important working landscape that supports biodiversity and vulnerable species in Pima County, Arizona (Huckelberry 2000). This semi-desert grassland, alluvial valley and 713,807-acre watershed composed of 39 subbasins serves as an aquifer to a portion of southwestern Tucson. This region of Southern Arizona has been identified...

  • A three-dimensional mapping of the ocean based on environmental data

    Creator:
    Wright, Dawn J.
    Abstract:
    The existence, sources, distribution, circulation, and physicochemical nature of macroscale oceanic water bodies have long been a focus of oceanographic inquiry. Building on that work, this paper describes an objectively derived and globally comprehensive set of 37 distinct volumetric region units, called ecological marine units (EMUs). They are constructed on...

  • New Treatments for HIV and Cancer: Uncovering Bioactive Compounds from Small Molecule Sources

    Creator:
    Overacker, Ross D.
    Abstract:
    Small molecule drugs have been instrumental in our fight against diseases, beginning when some of the earliest ancient cultures used plant remedies to treat illnesses. More recently, the skill of isolating and characterizing the active ingredients within bioactive plants and microbial extracts has led to the isolation and design of...

  • Beargrass (Xerophyllum tenax) in decline? An investigation into Region 6 harvest volumes

    Creator:
    Pape, Brianda
    Abstract:
    Non-timber forest products (NTFPs) have an extensive history of harvest in the United States. The Pacific Northwest is well-reputed as a major source of floral greens for international markets. One NTFP in particular, beargrass (Xerophyllum tenax), has been repeatedly identified as a prominent, high-value species in the floral greens industry...

  • Monotonic and Cyclic Testing of Cross-Laminated Timber Diaphragms

    Creator:
    Beairsto, Cody J.
    Abstract:
    Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete. Large, in-plane tests on cross-laminated timber...

  • Transdermal Delivery of Atenolol to Cats

    Creator:
    Mohamed, Sumeia M.
    Abstract:
    This thesis describes in-vitro and in-vivo evaluation of a transdermal atenolol formulation developed at Oregon State University, College of Pharmacy. The formulation was prepared from carbomer as a gel base with propylene glycol, glycerol, ethanol, polysorbate 80 and dimethyl-isosorbide (DMI) as mixture of penetration enhancing agents. The effect of the...

  • Emergent Properties of Animal Social Networks: Five Stories in Five Systems

    Creator:
    Devan-Song, E. Anne
    Abstract:
    Animals aggregate and interact in nonuniform and nonrandom patterns, which lead to group level characteristics that have important evolutionary and ecological consequences. Network analysis provides a useful conceptual framework for linking animal interactions at all scales from dyads to communities, to populations and ecosystems. Despite exciting theoretical and applied advances...
