  • Systematics of the genus Otidea in the Pacific Northwest

    Creator:
    Peterson, Eric T.
    Abstract:
    The fungal ascomycete genus Otidea as represented in the Pacific Northwest of North America includes eight well known species and two poorly-known species. Cladistic analysis utilizing characters from ribosomal DNA and morphology allowed the development of a robust phylogenetic species concept for Otidea. The combination of characters from the ribosomal...

  • Formative Work Toward a Mixed-Initiative Programming Language

    Creator:
    Abbott, Keeley
    Abstract:
    Mixed-initiative programming entails collaboration between a computer system, and a human to achieve some desired goal or set of goals. Often these goals change or are amended in real time during the course of program execution. As such, the plans these programs are based on must adapt and evolve to...

  • The computer, the computer user group, and the civil engineer

    Creator:
    Cunningham, Gerald Robert
    Abstract:
    An attempt to determine the relationship between the computer, the computer program exchange organization and today's practicing civil engineer has just been completed. A questionnaire was used to obtain information and opinions from 850 selected practicing civil engineers. Based on those questionnaires reaching their addresses, a return rate of 81.7...

  • Snag longevity, bird use of cavities, and conifer response across three silvicultural treatments in the Oregon Coast Range

    Creator:
    Walter, Scott T.
    Abstract:
    In the interest of meeting multiple forest management goals that include maintenance of wildlife, particularly cavity-nesting birds, uneven-aged silvicultural treatments are used increasingly in the Pacific Northwest. However, questions remain regarding the responses of cavity-nesting birds and residual green trees to different harvest intensities and patterns. To study these issues,...

  • Segmenting single-family homebuilders on a measure of innovativeness

    Creator:
    Fell, David R.
    Abstract:
    The goal of this study is to provide a better understanding of new product adoption by single family homebuilders. Information from this study will be useful to producers of new and existing engineered wood products in targeting their market development efforts. Homebuilders are studied with the goal of segmenting them...

  • Provenance, lifespan, and phylogeny : testing a conceptual framework for plant community management

    Creator:
    Benfield, Cara D.
    Abstract:
    Successful conservation management requires an understanding of how species respond to intervention. Native and exotic species may respond differently to management interventions due to differences arising directly from their native or exotic origin (i.e., provenance) or from differences in life-history or phylogenetic lineage that are associated with provenance. Thus, selection...

  • Evaluating the Effects of a Parasitic Copepod (Salmincola californiensis) on the Performance of Juvenile Chinook Salmon (Oncorhynchus tshawytscha)

    Creator:
    Neal, William T.
    Abstract:
    Pacific salmon (Oncorhynchus spp.) rearing in lakes and reservoirs have been known to become heavily infected with an ectoparasitic copepod (Salmincola californiensis). Little is known about the factors that affect the parasite infection prevalence and intensity. However, previous research suggests that the parasite may negatively affect the fitness and survival...

  • Prespawning Mortality of Fall Creek Willamette Chinook Salmon (Oncorhynchus tshawytscha): Evaluation of the Effects of a New Trap at the Adult Fish Collection Facility

    Creator:
    Carey, Katherine
    Abstract:
    Annual rates of prespawn mortality (PSM) in adult Chinook salmon (Oncorhynchus tshawytscha) trapped and transported upstream of dams in the Willamette River basin are high (often >40%) and could limit the ability to restore natural populations of spring Chinook salmon if not reduced. Improvements at the U.S. Army Corps of...

  • Patch dynamics of desert fishes in the arid wetlands of western Utah

    Creator:
    Sáenz, Jessica
    Abstract:
    The conservation of declining desert fish species requires the identification of relations between fish population dynamics and their environments. Dynamic occupancy modeling, an approach that requires less information than traditional mark-recapture studies, may help identify important factors affecting population processes and aid desert fish conservation and restoration efforts. I used...

  • Development of a Structured Adaptive Approach to Klamath Basin Sucker Recovery Planning

    Creator:
    Barajas, Miguel F.
    Abstract:
    Listed as endangered in 1988, the Lost River sucker (Deltistes luxatus) and Shortnose sucker (Chasmistes brevirostris) were once abundant and widely distributed in the Klamath Basin in Southern Oregon and Northern California. Populations of both species have been declining since the late 1960’s. Factors thought responsible for declines include naturally...
