White and grand fir are both valuable components of the mixed-conifer stand structure managed for late-successional reserves in central Oregon. However, they are often short-lived species because of high susceptibility to root diseases, defoliating insects, bark beetles, and wildfire. This study focuses on the effects of root diseases caused by...
Society derives many critical and irreplaceable values from forests. With a growing global human population and rates of consumption, forests are under increasing pressure to provide all these values simultaneously. To meet societal demands for wood products, tree plantations are becoming increasingly common and are replacing native forests. Yet, forests...
Since the 1980s, industrial forest restructuring has resulted in the divestment of industrial timberlands across the U.S. Emerging tenures have benefited from the divestment, including conservation-based tenures that manage for multiple objectives such as restoration, recreation access, and forest and habitat contiguity. Deschutes and Klamath Counties, Oregon, have three proposed...

Populated and developed areas at the fringes of or intermixed with undeveloped landscapes are referred to as the Wildland Urban Interface (WUI). There are many unique benefits associated with living in the WUI that understandably attract people to move to them. However, there are also potential wildfire-related risks particular to...
The ongoing worldwide loss of biodiversity has been described as a "biodiversity crisis," "the Anthropocene defaunation," and alternatively "an extinction spasm." More recently, many scientists have come to the conclusion that we are witnesses to Earth's sixth major mass extinction event, which has the potential to fundamentally alter basic ecological...
With the rapid advancement of educational technology and the need for personalized, engaging content to accommodate diverse learning needs, Virtual Reality (VR) holds promises for the present and future. However, VR applications suffer from challenges, including usability concerns, lack of pedagogical value, and evaluation standards. This thesis focuses on two...
I studied the water relations traits, twig conductivity, C'3 isotopic composition,
and wood density of three conifer and five angiosperm species in western Oregon. This
study took place from spring 2002 to fall 2003 on four sites. Species were selected to
represent the diversity of drought tolerance of woody plants...
Declining harvest levels, static agency research budgets, and increasing tension among scientists, managers, and industry members are the legacy of the present research and management institutions in the West Coast groundfish fishery. Cooperative research, the active participation of the commercial fishing industry in scientific research, is receiving increased attention as...
European hazelnut (Corylus avellana L.) is an important crop Oregon's Willamette Valley, producing 99% of the hazelnuts grown in North America and brings over US $60 million dollars to the region annually. Hazelnuts are rich in fiber and vitamins, as well in demand by consumers due to their popularity as...
Recommendations are provided in this watershed analysis to identify actions and management decisions on the part of BLM that might improve watershed health in the Trask River watershed.
The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...
In this thesis, I studied the translation of dengue virus RNA using a luciferase reporter gene system in Vero cells. The dengue reporter mRNA construct, which harbors 5´-terminal viral nts and 3´-terminal nts, could be translated efficiently compared to an alpha globin reporter construct. The 5´-cap structure and 3´-untranslated region...
At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...
The scarcity of wireless spectrum resources and the overwhelming demand for wireless broadband resources have prompted industry, government agencies and academia within the wireless communities to develop and come up with effective solutions that can make additional spectrum available for broadband data. As part of these ongoing efforts, cognitive radio...
