Genetic Characterization and Bioclimatic Modeling of the Three Varieties of Leptographium wageneri (Cause of Black Stain Root Disease) in the Western USA

Creator:: Choi, Daram
Abstract:: Black stain root disease (BSRD) is a vascular wilt disease of conifers caused by three varieties of the native, insect-vectored fungal pathogen, Leptographium wageneri (L. wageneri var. wageneri, L. wageneri var. ponderosum, and L. wageneri var. pseudotsugae). Although morphological, physiological, and ecological characteristics differ among the three varieties of L....

Overexpression of the GROWTH REGULATING FACTOR 4-GRF-INTERACTING FACTOR 1 Transcription Factor Chimera Modifies Transformation and Regeneration Efficiency in Populus and Eucalyptus

Creator:: Ryan, Nathaniel W.
Abstract:: Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...

Anadromous Salmonid Restoration in the Lower Crooked River : Can Collaboration and Legislation Coexist?

Creator:: McMurtrey, Owen S.
Abstract:: In watersheds across the American Pacific Northwest, changes in the cultural and regulatory landscape have increased pressure to restore and protect populations of anadromous fish. But restoration of anadromous fish populations constitutes a ‘wicked problem’, relentless in character, affecting diverse stakeholder groups, and defying ‘once and for all’ solutions (Weber...

Approaches for Characterizing Plant Physiological Responses to Environmental Stress

Creator:: Marias, Danielle E.
Abstract:: It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...

Genomic Resource Development for European Hazelnut (Corylus avellana L.)

Creator:: Rowley, Erik R.
Abstract:: 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...

Impacts of Swiss needle cast on Douglas-fir tree-ring stable isotopes and tree carbohydrate reserves

Creator:: Saffell, Brandy J.
Abstract:: Understanding the mechanisms of disease in forest pathology is a critical component to learning how to most efficiently manage tree diseases like Swiss needle cast (SNC). SNC is an economically important, fungal disease of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) that is prevalent in coastal areas of the Pacific Northwest. This...

Half-Sib Selection for Higher Betalains Concentration and Lower Total Dissolved Solids in Table Beets (Beta vulgaris)

Creator:: Hernandez, Monzarath
Abstract:: Betalains are a group of compounds that are major natural food colorants used by the food processing industry. These secondary compounds are found in only a few orders of plants with the Caryophyllales being the source of several domesticated crops. In particular, the family Chenopodiaceae in general and table beets...

Investigating the Genetic Control of Fusarium Root Rot Resistance in Snap Beans

Creator:: Huster, Abigail R.
Abstract:: Root rot diseases are a major constraint to bean (Phaseolus vulgaris L.) production around the world. Both snap beans and dry beans are affected. Root rot diseases can be caused by a variety of pathogens; however, Fusarium solani is a common causal agent. Fusarium root rot is a primary yield...

Evaluating "nuisance" beaver relocation as a tool to increase coho salmon habitat in the Alsea Basin of the central Oregon Coast Range

Creator:: Petro, Vanessa M.
Abstract:: Many stakeholders involved with stream restoration in the Pacific Northwest have discussed the potential benefits of using beaver dam construction activities (Castor canadensis) as a management tool to improve degraded stream habitat for anadromous salmon species. In addition, there has been growing interest in using nuisance beavers, primarily controlled by...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...
