Life History of the Northern Rubber Boa (Charina bottae) in Oregon

Creator:: Leppin, Mark V.
Abstract:: The Northern Rubber Boa (Charina bottae) is a small, secretive boa native to the Pacific Northwest. Despite this being possibly the highest latitude boas and one of only two boas native to the continental U.S., it has received surprisingly little attention. Most of the research on the natural history of...

The Examination of Escherichia coli Contamination via Agricultural Water Applications and Survival During Pre-Harvest Field Curing of Dry Bulb Onions

Creator:: Racine, Jason R.
Abstract:: 2020 and 2021 brought the first reported outbreaks of salmonellosis epidemiologically linked to dry bulb onions in the United States. Outbreak investigations were not able to implicate a specific source of the contamination but speculated that contaminated water was a significant contributor. The Produce Safety Rule established minimum standards for...

Evaluation of Stress Corrosion Cracking of 316L Stainless Steel in FLiNaK Using the Slow Strain Rate Technique

Creator:: Quintana, Xavier A.
Abstract:: Molten salts have been targeted as a promising coolant for next generation reactors due to their high boiling point, heat capacity, and thermal conductivity. Despite these benefits, molten salt systems present unique materials compatibility issues, highlighted by the aggressive corrosion attack and dealloying typically seen on materials in these environments....

Determining novel control methods for cabbage maggot (Delia radicum) in the Pacific Northwest

Creator:: Dugger, Chloe D.
Abstract:: Cabbage maggot, Delia radicum (Diptera: Anthomyiidae) impacts the production of Brassicaceae crops worldwide. The larva feed on the roots of crops causing reductions in yields due to impaired root function and unmarketability of crops. Chemical and cultural management programs are commonly used to control cabbage maggot with varying rates of...

Cleaning and Sanitizing Surfaces on Produce Farms: Optimizing What, How, and When

Creator:: Ohman, Erik
Abstract:: Production of fresh produce takes place outdoors, and therefore, is exposed to many routes of contamination (e.g., soil, contaminated water, manure, etc.) by human pathogens. Although precautions are taken to reduce this risk, pathogens can be regularly introduced to produce handling facilities. To manage the risk of cross-contamination from potentially...

Silviculture Impacts and Population Genomics of Coniferiporia sulphurascens, the Causal Agent of Laminated Root Rot

Creator:: McMurtrey, Shawn
Abstract:: Within the Pacific Northwest, USA, root diseases of conifers are a major forest health concern. These diseases are primarily caused by basidiomycete fungi. These fungal associates play a vital role in carbon sequestration but also have a significant negative economic impact within the timber industry. As a result, research on...

Agreeing to Nothing? Exploring the Role of Ambiguity in International Water Treaties

Creator:: Kaskina, Dina
Abstract:: Ambiguity is a typical element of treaty documents. Its success in accommodating divergent interests, creating boundary conditions leading to dispute prevention and facilitating the conclusion of agreements has been widely recognized, yet less is known whether or not intentional ambiguity or unintentional ambiguity, or perhaps both, lead to challenges or...

An Assessment of Black-backed Woodpecker (Picoides arcticus) Vital Rates in Green and Burned Forests within a Pyrodiverse Landscape Mosaic

Creator:: Kerstens, Mark E.
Abstract:: Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...

Assessing Post-fire Tree and Understory Vegetation Response to a Mixed-severity Fire Gradient in the Klamath Mts., Oregon, USA

Creator:: Terzioglu, Cihat
Abstract:: Severe wildfires are increasing in the western United States, impacting vegetation structure, and in turn, forest regeneration conditions. These wildfires are also raising a substantial amount of scientific and management concern regarding the resilience of forested ecosystems, or the ability of the ecosystem to return to a pre-fire condition. This...

Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

Creator:: Yang, Ping
Abstract:: Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...
