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...

Masters Thesis
Relationships between forest-floor invertebrate distribution, movement, and microclimate under alternative riparian management practices

Creator:

Rykken, Jessica J.

Abstract:

Headwater streams and their riparian zones are a common, yet poorly understood, component of Pacific Northwest landscapes. I sought to describe the ecological significance of headwater stream riparian zones as habitat for forest-floor invertebrate communities, and to assess how alternative management strategies for riparian zones may impact these communities. I...

Dissertation
Seasonal influences on food availability and diet of coastal cutthroat trout in relation to riparian vegetation

Creator:

Romero, Nicolas

Abstract:

Current riparian management objectives in the Pacific Northwest promote both retention of existing conifers and conversion of hardwood-dominated areas to conifers. Although understanding of relationships between riparian vegetation and salmonid prey availability is growing, temporal variation in these relationships is poorly understood. Seasonal fluxes in availability of aquatic and terrestrial...

Masters Thesis
Seasonal dynamics of a riparian food web in the Oregon Coast Range mountains

Creator:

Robillard, Amanda Lynn

Abstract:

Riparian areas are eco-tones where aquatically- and terrestrially-derived insect biomass is exchanged between habitats, presenting consumers with new sources of energy, and resulting in a reciprocal subsidy. The relative contribution of energy exchange and the resulting impacts on vertebrate riparian consumers, such as fish or birds, remains poorly understood. We...
