  • Social Learning and Adaptive Capacity in Collaborative Watershed Partnerships

    Creator:
    Calvert, Daniel T.
    Abstract:
    This dissertation examines learning driven adaptations in salmon recovery efforts and water resources management in Oregon. The case study utilizes a framework highlighting the connections between human and natural systems. Semi-structured interviews are used to analyze interactions between rural riparian landowners and watershed council staffs living and working in Oregon’s...

  • The effects of logging on periphyton communities of coastal streams

    Creator:
    Hansmann, Eugene W. (Eugene William), 1933-
    Abstract:
    The purpose of this study was to investigate the effects of logging on the productivity, structure and biomass of a periphyton community developed in mountain streams. The three streams used in this investigation were located in the coast range of Lincoln County, Oregon. They were selected for similarity of habitat,...

  • Factors Influencing Streamflow Generation Processes in Rain-dominated, Coastal Watersheds in Oregon

    Creator:
    Pazdral, Rosemary
    Abstract:
    Relative to other systems in the PNW, the rain-dominated, coastal watersheds of western Oregon have shallow aquifers. Given the seasonality of streamflow and storage limitations in coastal, rain-dominated watersheds, changes in the temporal patterns of precipitation have the potential to magnify the risk of extreme streamflow conditions during both high-...

  • Plant communities and succession in Oregon coastal salt marshes

    Creator:
    Jefferson, Carol A.
    Abstract:
    The purpose of this study was to determine plant species composition, community structure, successional relationships, vegetational development and plant distributions in estuarine salt marshes on the Pacific Coast of Oregon. Quadrat and transect samples of plant presence and cover, collected from April 1971 - June 1974, were subjected to phytosociological...

  • Contextual systems description of an Oregon coastal watershed

    Creator:
    Goetze, Brigitte
    Abstract:
    Many resource management controversies indicate disagreement about the possible intended and unintended effects of management actions on ecosystems. Researchers have documented a variety of negative effects on specific ecosystems, e. g. the degradation of salmonid habitat due to mass wasting (Hagans et al. 1986). While the effects of some management...

  • Voices from the coast : drawing on family funds of knowledge to build ocean literacy and home school partnerships

    Creator:
    Roebber, Susan Merwin
    Abstract:
    In this qualitative study, ethnographic methods were used to identify parent funds of knowledge related to ocean literacy in a rural, coastal context. Participants included 16 parents of students in the teacher-researcher's third-grade classroom. Interactions between parent-child, parent-parent, and parent and the teacher-researcher were studied in order to determine factors...

  • Redd site selection and spawning habitat use by fall chinook salmon

    Creator:
    Geist, David R.
    Abstract:
    The spawning habitat associated with fall chinook salmon (Oncorhynchus tshawytscha) redd clusters was investigated in the Hanford Reach of the Columbia River. A conceptual spawning habitat model is proposed that describes how geomorphic features of river channels create hydraulic processes, including hyporheic flows, that influence where salmon spawn in unconstrained...

  • On the estimation and application of spatial and temporal autocorrelation in headwater streams

    Creator:
    Som, Nicholas A.
    Abstract:
    This collection of three manuscripts serves to improve methods for collecting, interpreting, and utilizing autocorrelated data from headwater stream networks. Each stream network is comprised of linear segments. These segments lie within a unique branching structure that connects the segments via flowing water, and the connectivity provided by water varies...

    Creator:
    Bellinger, M. Renee
    Abstract:
    Substantial scientific investment has been directed towards understanding factors that influence distribution patterns and animals' remarkable ability for precise orientation and navigation, yet fundamental gaps in our knowledge remain. In my dissertation, I applied emerging genetic technologies to conduct a top-down and bottom-up investigation of animal movement and cue perception....

  • Investigating Demographic and Evolutionary Factors Important for Fish Reintroduction

    Creator:
    Sard, Nicholas M.
    Abstract:
    Reintroduction programs are used to re-establish species back into their historical habitat. Most reintroduction programs have failed and few papers have evaluated factors that may be important to Pacific salmon. The 158 meter tall Cougar Dam has blocked Chinook salmon (Oncorhynchus tshawytscha) from accessing 40 kilometers of historical spawning and...
