Creator:: Larson, Keith R.
Abstract:: Sediment yield increases following timber harvest and road construction were predicted for four Pacific Northwest experimental watersheds. Sediment yields were predicted using a handbook developed by the U.S. Forest Service entitled, "An Approach to Water Resources Evaluation of Non-Point Silvicultural Sources" (WRENS). Predicted sediment yield increases varied from 40 to...

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...

Creator:: Hale, V. Cody
Abstract:: This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...

Creator:: Sheehy, Samantha
Abstract:: Although the Pacific Northwest has the least proportion of non-native plant species in relation to other regions of North America, exotic species continue to spread into mountainous areas, including the Cascade Range. In a forested landscape, road networks can act as corridors for exotic plant dispersal and establishment, helping species...

Creator:: Chaer, Guilherme M.
Abstract:: The objectives of this thesis were to evaluate the responses of soil microbial communities to physical and chemical disturbances, and associate these responses with soil functional stability and changes in soil quality. The first study consisted of application of heat shocks (HS) to soils with contrasting land use history to...

Creator:: Moore, Sean M.
Abstract:: Like other species interactions in ecological systems, host-pathogen interactions are influenced by environmental factors, landscape characteristics and the broader community context. My thesis explores the potential influences of food-web interactions (Chapter 2), climate change (Chapter 3), landscape structure and host movement patterns (Chapter 4), and the combined influences of local...
