  • Brassicaceae Seed Persistence and Dormancy in the Willamette Valley

    Creator:
    Flick, Gabriel D.
    Abstract:
    Producers in the Willamette Valley of Oregon are interested in growing canola as a rotational crop in grass seed and cereal rotations. Many other Brassicaceae seed crops also are produced within the valley. Concerns of seed persistence and volunteer contamination of Brassicaceae seed crops prompted the investigation of seed persistence...

  • The light within us : Quaker women in science

    Creator:
    McCabe, Leslie N.
    Abstract:
    This thesis explores the role of Quaker women in science in an attempt to arrive at some understanding of what motivated Quaker women in nineteenth century America to go into the sciences. George Fox founded the Society of Friends in the mid-seventeenth century in England and the Quaker theology centered...

  • Investigating the Paleoseismic Potential of Small, Southern Cascadia Lakes

    Creator:
    Ross, Ann Elizabeth Morey
    Abstract:
    Marine and coastal sedimentary archives show that the Cascadia Subduction Zone can generate great earthquakes of ~M9, most recently in 1700 CE, yet we still know little of the impacts of these events inland of the Pacific coast. Inland lakes have recently been exploited for their use as paleoseismic records...

  • Trinexapac-ethyl and open-field burning in creeping red fescue (Festuca rubra L.) seed production in the Willamette Valley

    Creator:
    Zapiola, Maria Luz
    Abstract:
    Open-field burning has been an effective, economical, and widespread method of post-harvest residue management in creeping red fescue seed production in the Willamette Valley since the late 1940s. However, the use of field burning has been legislatively restricted due to air quality and safety issues. The foliar-applied plant growth regulator...

  • Dynamics of Zymoseptoria tritici Fungicide Resistance in the Willamette Valley of Oregon

    Creator:
    Hagerty, Christina H.
    Abstract:
    The development of resistance to multiple fungicide classes is currently limiting disease management options for many pathogens, while the discovery of new fungicide classes has become less frequent. To address this pressing issue, a three-part study with different layers of complexity, objectives, and experimental approaches was conducted using the model...

  • Population Ecology of the Mariana Swiftlet (Aerodramus bartschi) on O'ahu, Hawaiian Islands

    Creator:
    Johnson, Nathan Christopher
    Abstract:
    The Mariana Swiftlet (Aerodramus bartschi) (Aves: Apodidae) is endemic to the Mariana Islands, where it currently occurs on Saipan, Aguiguan, and Guam. An introduced population of Mariana Swiftlets is also present on O'ahu in the Hawaiian Islands. Sparing interference with the endangered population in the Marianas, the introduced, surrogate population...

  • Mapping Wildlife-Relevant Snow Properties in Arctic-Boreal North America; Novel Modelling, Remote-Sensing, and Ground Observation Approaches

    Creator:
    Cosgrove, Christopher Liam
    Abstract:
    Arctic-boreal regions are exhibiting the symptoms of profound ecological shifts as they experience pronounced warming. Wildlife in high-latitudes are one such harbinger of change, and their populations are undergoing range-shifts, declines, and extinctions in response to their rapidly altering habitats. As the circumpolar and boreal north is snow-covered for up...

  • White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

    Creator:
    Viste-Sparkman, Karen
    Abstract:
    Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...

  • Influence of wetland landscape structure of shorebirds wintering in an agricultural valley

    Creator:
    Taft, Oriane Williams
    Abstract:
    Understanding how wetland birds use habitat is pivotal to developing successful and beneficial conservation strategies. Although it has been an ardent topic in forest research for some time, how species interact with the spatial patterning of habitat across a landscape (i.e., landscape structure) has been more or less neglected in...

  • Soil organic matter management and root health

    Creator:
    Darby, Heather
    Abstract:
    Annual applications of fresh or composted dairy manure were assessed for their effects on root rots of sweet corn and snap bean and damping-off of cucumber in a field soil. Soil biological and physical properties were measured as possible indicators of root rot suppressive potential. Regardless of amendment type or...
