  • Bottom-up Drivers of Primary Producers and Predator Populations in Oregon Streams

    Creator:
    Kaylor, Matthew J.
    Abstract:
    Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...

  • Experiments and Observations on How Changes in Riparian Forests Affect Light and Stream Ecosystems

    Creator:
    Swartz, Allison G.
    Abstract:
    Riparian zones are ecotones between terrestrial and aquatic ecosystems. Processes in streams are strongly influenced by riparian forest communities, age, stage and structure. Temperate forests across much of North America, including riparian areas, are recovering from historic land clearing with many stands in the stem-exclusion phase of development in which...

  • Stream Temperature and Autotrophic Responses to Riparian Canopy Gaps Over Forested Headwater Streams

    Creator:
    Swartz, Allison
    Abstract:
    Across much of North America, legacies of historic and contemporary timber harvest have created a landscape dominated by regenerating forest stands in the early to middle stages of development. Most streamside forests are currently in the stem-exclusion phase of stand development and these closed canopies shade the forest understory and...
