  • Species specific phytoplankton production rates during a spring diatom bloom in Yaquina Bay, Oregon

    Creator:
    McMurray, Gregory R., 1925-
    Abstract:
    A simplified autoradiographic method for estimating species-specific phytoplankton production rates in mixed natural communities was evaluated in the laboratory and employed in the field. Laboratory experiments were designed to test the reliability and variability of the simplified method. Assays of ¹⁴C uptake by liquid scintillation spectrometry were used to evaluate...

  • Spatial and temporal variations of bioavailable polycyclic aromatic hydrocarbons in the lower Willamette River

    Creator:
    Sower, Gregory J.
    Abstract:
    Urban rivers with a history of industrial use can exhibit spatial and temporal variations in contaminant concentrations that may significantly affect risk evaluations and assessment of remediation efforts. To more effectively estimate human and ecological health risks, we evaluated the spatial and temporal distribution of polycyclic aromatic hydrocarbons (PAHs) in...

  • Soil mounds and patterned ground of the Lawrence Memorial Grassland Preserve

    Creator:
    Johnson, Colleen Burch
    Abstract:
    The Lawrence Memorial Grassland Preserve, located in Wasco County, Oregon, exhibits a wide variety of soil mounds and patterned ground features. The size, shape, and distribution of several elements of this peculiar landscape were analyzed with a detailed map, field observations, and statistical procedures. Common soil mound shapes are circular,...

  • Continuous Flow Microwave-Assisted Synthesis as a Potentially Scalable Nanomanufacturing Approach

    Creator:
    Albuquerque, Gustavo Henrique T. C. de
    Abstract:
    The development of nanomaterials and the potential enhancement of their chemical, mechanical, electrical, and optical properties have led to the investigation of methods for their synthesis at lower cost with enhanced performance for next generation devices. Along with the pursuit of new materials that exhibit properties of interest, industry requires...

  • Effects of ultraviolet-B radiation on marine phytoplankton

    Creator:
    Behrenfeld, Michael Joseph
    Abstract:
    Global increases in ultraviolet-B radiation (UVBR:290- 320 nm) resulting from decreases in stratospheric ozone concentration have the potential to alter marine primary production and affect global climate and marine trophic dynamics. Effects of UVBR on phytoplankton carbon fixation were determined from open ocean exposure studies conducted off the coast of...

  • Habitat utilization by minke whales (Balaenoptera acutorostrata) in the St. Lawrence Estuary, Canada

    Creator:
    Zeppelin, Tonya K.
    Abstract:
    Characteristics of minke whale (Balaenoptera acutorostrata) habitat at the head of the Laurentian Channel in the St. Lawrence Estuary, Canada were identified by quantifying environmental and temporal habitat variables and comparing them to the presence or absence of minke whales during the summer of 1996. Identification photographs of minke whales...

  • Perceptions of agricultural education teacher preparation programs toward distance education

    Creator:
    Nelson, Susanne J.
    Abstract:
    The purpose of this study was to identify if differences existed in perceived barrier factors and perceived attitude factors toward distance education between faculty and administrators in the decision stage and those in the implementation stage of distance education technology adoption. Information was gathered from teaching faculty and program leaders...
