  • Integrating solute transport, metabolism and processing in stream ecosystems

    Creator:
    González Pinzón, Ricardo A.
    Abstract:
    After three decades of active research coupling hydrology and stream ecology, the connection among solute transport, metabolism and processing is still unresolved. These knowledge gaps obscure the functioning of stream ecosystems and how those ecosystems interact with other landscape processes. We must resolve these challenges to wisely manage water resources,...

  • Determining the relationship between measured residence time distributions in lateral surface transient storage zones in streams and corresponding physical characteristics

    Creator:
    Coleman, Anthony M.
    Abstract:
    Surface transient storage (STS) in stream ecosystems serve an important function in retaining nutrients and refugia for aquatic communities. Unfortunately, they can retain contaminants as well. Therefore, it is of importance to determine the residence time distribution (RTD). A RTD of a particular STS zone encompasses the time it takes...

  • Drought, dispersal, and community dynamics in arid-land streams

    Creator:
    Bogan, Michael T.
    Abstract:
    Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; these processes act as filters that reduce the regional species pool down to the observed local community. In...

  • Meander scars : reflections on healing a river

    Creator:
    Metzger, Abby P.
    Abstract:
    As Europeans settled the Willamette Valley in the 1800s, they began to simplify Oregon's largest river contained wholly within state boarders—the Willamette. The river lost miles of channels from dikes, dams, and development. Some channels vanished under concrete. Others became meander scars, or shallow, dry depression in the land where...

  • Beaver ecology in Bridge Creek, a tributary to the John Day River

    Creator:
    Maenhout, Julie L. (Harper)
    Abstract:
    The American beaver (Castor canadensis) was nearly extirpated by the late 1800's due to the fur trade. Due to reintroduction efforts, it now occupies much of its former range. Beavers are a keystone species and ecosystem engineers, greatly influencing riparian and instream habitats through selective harvesting of plant materials and...
