  • Effects of esfenvalerate on native macroinvertebrates representative of Pacific Northwest streams

    Creator:
    Johnson, Katherine R.
    Abstract:
    Aquatic insects are essential components of healthy stream ecosystems, contributing to nutrient cycling, trophic dynamics and other ecological functions. Aquatic insect species, particularly those in the orders Ephemeroptera, Plecoptera and Trichoptera (EPT taxa) are however, extremely sensitive to insecticide contamination. Given that urban and agricultural use of synthetic pyrethroid insecticides...

  • The Impacts of Multiple Stressors on Aquatic Invertebrate Communities in the Umatilla River

    Creator:
    Clark, Hannah
    Abstract:
    Rivers impacted by human activities often have multiple stressors present. The effects of multiple stressors on biological communities can often be difficult to predict, due to the potential for complex interactions between stressors and communities. This thesis explores the impacts of two stressors often associated with agricultural land use, increased...
