Marine Heatwaves Influence Depth Preferences of Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Teahan, Andrew
Abstract:: Marine heatwaves have become more common over the past several years. The 2014-2015 ‘warm blob’ had profound effects on marine ecosystems in the Northeast Pacific. Given the particular habitat needs of Chinook Salmon (Oncorhynchus tshawytscha) we wanted to examine the impacts of the heatwave on Chinook depth distribution. We examined...

Dry-Hop Induced Refermentation: An Overview and an Investigation of Agronomic Influences on Hop Diastatic Potential

Creator:: Stokholm, Arnbjørn
Abstract:: Beer brewing, broadly speaking, consists of two stages, a hot side and a cold side. The hot side occurs in the brewhouse and consists of steeping malted grain in hot water to extract sugars, separating the steeping liquid (wort) from the solids, and boiling the wort with an addition of...

Development from a Distance: Exploring International Non-profit Interactions with Communities during the COVID-19 Pandemic

Creator:: Peiffer, Ashley K.
Abstract:: The COVID-19 pandemic impacted the international development sector through various external and internal stressors. Community engagement practices that international non-governmental organizations and non-profits conducted were disrupted by the pandemic, and communities were faced additional challenges when international development workers were required to socially distance or relocate at the onset of...

Monotonic and Cyclic Testing of Cross-Laminated Timber Diaphragms

Creator:: Beairsto, Cody J.
Abstract:: Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete. Large, in-plane tests on cross-laminated timber...

The Biotransformation of Hop Aroma: An Exploration into Yeasts' Ability to Release Polyfunctional Thiols in Beer

Creator:: Molitor, Richard W.
Abstract:: The biotransformation of hop aroma via yeast is a prominent topic in the brewing industry with considerable interest placed on how yeast can enhance volatile thiol production during wort fermentation. Three potent thiols are known contributors to tropical qualities in wine and beer aroma, specifically 3-mercaptohexan-1-ol (3MH), 3-mercaptohexyl acetate (3MHA),...

Examining Environmental and Genetic Influences on the Brewing Performance of Hops (Humulus lupulus) and Barley (Horduem vulgare)

Creator:: Van Simaeys, Karli R.
Abstract:: In short, the brewing process uses hot water to extract fermentable sugars from malt to make a wort that is bittered by hops and finally fermented by yeast to produce beer. The four key ingredients in brewing are malt, water, hops, and yeast. Malt is perhaps the key ingredient, as...

Development of Diagnostic Assays for Race Differentiation of Podosphaera macularis

Creator:: Block, Mary H.
Abstract:: Hop powdery mildew (Podosphaera macularis) was confirmed in the Pacific Northwest in 1996. Before 2012, the most common race of P. macularis was able to infect plants that possessed powdery mildew resistance based on the R-genes Rb, R3, and R5. Post 2012, two additional races of P. macularis were discovered...

Assessing Seismic Rockfall Impacts on Mobility in Transportation Corridors

Creator:: Holtan, Katherine
Abstract:: The climate and geologic conditions of the Pacific Northwest leaves its roads highly susceptible to rockfall hazards. Rockfalls often occur on steep slopes that experience heavy rainfall, groundwater seepage, or strong shaking from earthquakes. The unpredictable nature of these events often creates substantial problems for communities, transportation infrastructure, and the...

Pacific Madrone Leaf Blight Detection with Unmanned Aerial Systems and Machine Learning

Creator:: Barker, Matthew I.
Abstract:: Ground-based assessments of foliar diseases including leaf blight are time-consuming and costly. We investigated the potential for using an unmanned aerial system (UAS) in conjunction with a multispectral sensor to determine whether we could more efficiently and reliably detect and quantify leaf blight in Pacific madrones. Our methods included ground-based...

Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...
