The concept of "adaptive governance" represents a spectrum of hybrid approaches to environmental governance employed to guide management of complex social-ecological systems under conditions of high uncertainty. While the concept of adaptive governance has benefited from over a decade of theoretical development, empirical examples of transitions towards adaptive governance are...
Irrigated agriculture accounts for 90 percent of consumptive use of freshwater in the western US and is considered the largest contributor to nonpoint source water pollution. The diffuse nature of most water quality and quantity challenges necessitates institutions that can more effectively engage agricultural producers in strategic, integrated, watershed-scale approaches...
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...
This thesis is a report of a phenomenological-informed study of public university student spiritual development. The research was based primarily upon semi-structured personal interviews and a focus group with undergraduate students at a large, public research institution on the west coast. Since the introduction of scientific objectivity into the academy...
The effects of ¹⁵N-labeled fertilizer applied to mature summer-bearing red raspberry (Rubus idaeus L.) plants were measured over two years. Four nitrogen (N) treatments were applied singularly at 0, 40, or 80 kg·ha⁻¹ of N in early spring (budbreak), or split with 40 kg·ha⁻¹ of N (unlabeled) applied at budbreak...
1,4-dioxane, a probable human carcinogen at low (< 1ppb) concentrations, has emerged as a groundwater contaminant due to its historical use as a stabilizer for the chlorinated solvent 1,1,1-trichloroethane. Aerobic cometabolism, the use of a primary substrate to induce the production of microbial enzymes that fortuitously degrade other compounds, is...
Tribal water rights and instream flows for species listed under the Endangered Species Act (ESA) have been a source of tensions in the western United States, particularly when tribes have undetermined water rights to support tribal fisheries listed under the ESA. Understanding the mechanics of past tribal settlements and their...
In ecological restoration, species that are sown to increase the native plant
diversity range in establishment ability. Some species readily establish, while others
rarely do. This study set out to investigate some of the potential processes influencing
species establishment, as well as the traits that are associated with the success...
For adult learners to succeed in their educational endeavors, adult educators and event planners must meet their needs and goals (Storksdieck, Ellenbogen, & Heimlich, 2005). The learning environment affects how adults learn and what outcomes they achieve (e.g., Hamilton & Tee, 2010; Knowles, 1990; Lim, Morris, & Kupritz, 2007; Young,...
Concern over the increasing proportion of juvenile wood grown in second growth plantations has led to a large amount of research on the effects of common silvicultural practices on wood quality. Lacking is research on the effect of timing and
duration of vegetation control on wood quality near the pith...
