  • Examining ectomycorrhizal communities of ponderosa pine and lodgepole pine in the south-central Oregon pumice zone

    Creator:
    Garcia, Maria Osuna
    Abstract:
    Background information is presented that provides historical perspectives on the field of mycology in the Pacific Northwest and its role in forest management. The series of events and decisions that have led to previous studies (or lack of studies) in the field also dictate the directions of current research. Culture,...

  • Ontogenetic Shifts in Disease Response in Native and Invasive Anuran Species

    Creator:
    Urbina Gonzalez, Jenny Cecilia
    Abstract:
    This dissertation presents a different approach to understanding how amphibians are responding to disease through ontogeny. Although numerous efforts have been conducted to understand host responses to the fungus Batrachochytrium dendrobatidis (Bd), studies have been restricted to distinct developmental stages. This dissertation provides information on host response to Bd across...

  • Demand and profitability for albacore products : a multi-attribute analysis

    Creator:
    Garcia-Martinez, Salvador
    Abstract:
    The main purpose of this research is to provide the commercial seafood industry of the Pacific Northwest information on preferences of restaurateurs, retailers, and wholesalers for whole albacore, low-value added albacore products (chunks, medallions, and steaks), albacore loins, and high-value added albacore products (hot smoked and lox). All of these...

  • Metabolic Effects in C57B/6J Mice Fed a High-Fat Diet Supplemented With Walnuts, Raspberries and Other Whole Foods

    Creator:
    Miranda-Garcia, Omar
    Abstract:
    Health benefits obtained from consumption of fruits and vegetables have the potential to improve the lifestyle of individuals. The walnut is a polyunsaturated fatty acid (PUFA)-rich whole food that is readily available in the U.S and has been shown to potentially reduce risk of Metabolic Syndrome. Furthermore, consumption of polyphenol...

  • Community Colleges Creating Academic Programming for Rural Areas

    Creator:
    Garcia-Chitwood, Jean
    Abstract:
    Community colleges serve various populations as part of their missions. Many community colleges serve the people who live in rural communities and are challenged with fewer financial resources. The term rural is not easily defined, and many variables need to be considered when creating academic programming for rural populations. There...

  • Approaches for Characterizing Plant Physiological Responses to Environmental Stress

    Creator:
    Marias, Danielle E.
    Abstract:
    It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...

  • Movement of zoospores of Phytophthora citricola in saturated porous media

    Creator:
    Ochiai, Naoyuki
    Abstract:
    The genus Phytophthora comprises numerous plant pathogens in both natural and managed ecosystems. For Phytophthora spp. that infect roots, dispersal occurs in soil water through a combination of advection and swimming of specialized motile propagules (zoospores). Specific biological and physico-chemical processes, however, remain poorly understood, due to difficulties in studying...

  • Ectopic overexpression of Arabidopsis CBF genes enhances freezing tolerance of two potato species

    Creator:
    Pino, María-Teresa
    Abstract:
    Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...

  • Ultrafiltration of grape juice by hollow fiber membranes

    Creator:
    Garcia-Quintero, Zeferino Heberto
    Abstract:
    The feasibility of using hollow fiber ultrafi1tration for clarification, stabilization and preservation of white grape juice was evaluated. Flux and process parameters of a hollow fiber membrane ultrafi1tration unit (Romicon pilot scale, model FXS-MXII), were studied using white Riesling grape juice. Optimum processing conditions were determined for different nominal membrane...

  • Water management effects on birdsfoot trefoil seed production

    Creator:
    García-Díaz, Carlos Alberto
    Abstract:
    There is no information available on water management of birdsfoot trefoil grown for seed. Information is also not available describing how to minimize seed losses due to shattering in order to obtain consistently high birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify crop water use,...
