  • 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...

  • Description and analysis of dietary preference of lingcod in the nearshore zone, Oregon

    Creator:
    Tinus, Craig A.
    Abstract:
    The lingcod (Ophiodon elongatus) is an important groundfish species in both recreational and commercial fisheries of the Northeastern Pacific. It is a large, fast-growing, generalist predator of invertebrates and fishes. In response to concerns that lingcod may limit populations of rockfishes (Sebastes spp.), I compared the diets of 375 adult...

  • Local weather, regional climate, and population dynamics of northern spotted owls in Washington and Oregon

    Creator:
    Glenn, Elizabeth M.
    Abstract:
    Since the early 1990s, declines in northern spotted owl (Strix occidentalis caurina) populations have been documented through extensive field surveys and range-wide demographic analyses. Although loss of late-successional forest has been credited as the primary cause for spotted owl population declines, environmental variation has also been shown to influence vital...

  • Sustainable construction safety and health rating system

    Creator:
    Rajendran, Sathyanarayanan
    Abstract:
    The main objective of this research study is to incorporate construction worker safety and health into sustainable design and construction practices. This can be fulfilled by the development of an innovative construction worker safety and health planning tool, called Sustainable Construction Safety and Health (SCSH) Rating System that will: •...

  • Wide band gap semiconductors and insulators : synthesis, processing and characterization

    Creator:
    Hersh, Peter A.
    Abstract:
    The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

  • On the evolution of correlated color traits in garter snakes

    Creator:
    Westphal, Michael F.
    Abstract:
    How complex traits evolve continues to be a major focus of evolutionary investigation. A current topic of debate is the hypothesis that the phenotypic integration of complex traits gives rise to evolutionary constraints. I studied two color traits in the common garter snake, Thamnophis sirtalis, that show a high level...

  • Evaluating Biochar for the Sustainable Treatment of Heavy Metals in Stormwater: Characteristics, Mechanisms, and Barriers

    Creator:
    Burch, Sarah
    Abstract:
    Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...

  • The great fires : Indian burning and catastrophic forest fire patterns of the Oregon Coast Range, 1491-1951

    Creator:
    Zybach, Bob
    Abstract:
    The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...

  • Experimental analysis of task prioritization training for a group of university flight technology students

    Creator:
    Hoover, Amy L.
    Abstract:
    Task prioritization performance was evaluated for pilots who participated in a concurrent task management (CTM) training course and pilots who did not. CTM is the process by which pilots selectively attend to high priority tasks and shed non-priority tasks. Twenty seven pilots enrolled in a university flight technology program were...

  • Nearshore distribution of barnacle and mussel larvae and oceanographic mechanisms of onshore transport and delivery

    Creator:
    Tyburczy, Joe A.
    Abstract:
    Recruitment of larvae from the plankton is an important determinant of community structure in marine systems. In populations of many marine species, recruitment determines the basic demographic parameters of immigration, emigration, and reproduction. Moreover, the effect of recruitment as an "ecological subsidy" can determine the strength of interactions among species...
