The Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins) can kill large numbers of Douglas-fir trees (Pseudotsuga menziesii (Mirbel) Franco) across a landscape during periods of population outbreaks. High-value individual trees and small stands can be protected from Douglas-fir beetle infestation during outbreaks by applying the anti-aggregation pheromone, MCH (3-methylcyclohex-2-en-1-one). MCH treatments are...
Individuals in their 20s today have more diverse experiences with school, work, and family transitions than previous cohorts. Contemporary young adults take longer to finish school, settle into marriages or partnerships, and begin parenting; they frequently change jobs or hold multiple part-time positions. Little is known about how young adults...

While a number of scholars in the field of Rhetoric and Composition continue to reassert the importance of whiteness as an object of study, a sense of anxiety about the effectiveness of extant antiracist rhetorical practices permeate recent scholarship. This thesis engages with thinking from black studies, afropessimism, and transnational...
In the US, a disease is classified as rare if it affects less than 200,000 individuals a year. Despite considerable similarities, individuals with rare diseases (RDs) report worse life quality and satisfaction with life (SWL) than those with common chronic conditions. One potential avenue to increase SWL is through improving...
Positive youth development posits that all youth possess the capacity to change and grow as they interact with their contexts. That capacity is activated and nurtured by a beneficial ecological environment often unavailable for homeless youth. Only a limited number of studies focus on the positive development and strengths of...
A cultural landscape analysis of two historic cemeteries in St. Paul, Oregon demonstrates that the residents of this early community were unknowingly using grave markers to express their worldview and the identities that they felt were most important. Because of the historical and cultural development of this community as the...
The number of women in doctoral programs is increasing each year and women now comprise the majority of doctoral students in America (U.S. Department of Education, 2015). Previous research has shown the high levels of complexities and stresses that female doctoral students face during their studies (Mallinckrodt & Leong,1992) and...

Platelet activation uses a complex set of pathways to respond to vascular injury during hemostasis. However, thrombosis relies on the same set of pathways. Antiplatelet therapies used to prevent thrombotic events often target the P2Y₁₂ platelet receptor for inhibition but can result in bleeding diathesis or in abnormally high ADP...
For nearly two decades, foresters in the Oregon Coast Range have been witnessing a substantial decease in Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco.) vigor and growth, caused by Swiss needle cast (Phaeocryptopus gaeumannii). Currently, no solutions are in sight but aerially-applied sulfur may alleviate Swiss needle cast and its...
An improved understanding of the ecohydrologic relationships in semiarid rangelands is imperative for the development of effective rehabilitation and land management practices. This thesis addresses the ecohydrologic relationships of two significant issues concerning semiarid rangeland ecosystems: western juniper encroachment and increasing stream temperatures.
This thesis is divided into two chapters;...
In the case of lake management for recreational use, policy makers often face a balancing act. They must maintain both the ecological quality of sites and the welfare of recreationists. In Wisconsin's Northern Highland Lake District, recreational boaters inadvertently transport aquatic invasive species between lakes. Economic models of boater demand...
The population of dusky Canada geese (Branta canadensis occidentalis; hereafter, dusky geese) nesting on the western Copper River Delta (CRD) in south- central Alaska has been in decline since the late 1970s. In an effort to alleviate mammalian predation, increase nest success, and avoid a listing under the U.S. Endangered...
Despite many studies of large wood in streams, few landscape scale studies have been conducted. Large-scale studies can reveal how the history of forest harvest and road building has influenced wood patterns in streams of the Pacific Northwest. This study examined the relationships between wood in streams, timber harvest, and...
Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...
Many children with developmental disabilities are not engaging in the recommended amount of daily physical activity (Pan, 2008; Shields, Dodd, & Abblitt, 2009; Whitt-Glover et al., 2006), which can lead to additional health disparities and decreased quality of life for children in this population (Field & Jette, 2007). The relationship...
In light of water scarcity and the impacts of climate change, there is an increased need to understand the interaction between land use characteristics and ecohydrologic processes in semiarid regions. Additionally, many semiarid and arid regions face various land management challenges, including woody plant encroachment, decreased snowpack, and increased stream...

Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...
A previous study conducted in our laboratory demonstrated the critical role that retronasal odors play in vegetable liking and disliking. It remains unclear, however, why some individuals like certain vegetable odors, while others do not. A possible explanation is that some individuals have learned to like the odor of a...
Linear M-mode (1D) and later 2-dimensional (2D) measurements of the left atrium (LA) are commonly been used to assess LA size in veterinary studies despite the fact that studies in human subjects have shown that LA volume (LAV) more accurately reflects LA size than linear measurements due to the complex...
Understanding the tradeoff between water use and productivity is critical for modeling growth of intensively managed Douglas-fir forests in the Pacific Northwest. Evapotranspiration is closely linked to carbon dioxide intake during the process of photosynthesis. However, summer drought characterizing the growing season in this region imposes a limit on carbon...
Organic semiconductors have attracted considerable attention due to their applications in low-cost, solution-processable (opto)electronic devices. An important class of high-performance organic semiconductors is pentacene derivatives, which exhibit high charger carrier mobilities in field-effect transistors and ultrafast singlet fission in photovoltaic devices. These derivatives have served as benchmark materials for systematic...
