Antifungal Properties of Spotted Wing Drosophila (Drosophila suzukii) Larvae

Creator:: Bernert, Ann
Abstract:: Spotted wing drosophila, Drosophila suzukii, is a recently introduced, invasive pest in Oregon. It oviposits in near-mature and mature fruit, and thus is an important concern for the small fruit industry. A crop consultant observed that mature raspberry fruit with D. suzukii larvae do not show symptoms of molds as...

Low Cloud Point Biodiesel

Creator:: Johnson, Shanti Christopher
Abstract:: The synergetic interplay between the removal of saturated methyl esters and the addition of deoxygenated fatty acids on depressing the cloud point temperature of biodiesel was investigated in this study. Canola biodiesel was produced in batch as a standard with a cloud point of 1.37 +/- 6.3°C. Saturated methyl esters...

Case studies : Using the zebrafish to evaluate neurobehavioral phenotypes

Creator:: Garcia, Abraham, Truong, Lisa, Johnson, Eric, Tanguay, Robert L., and Knecht, Andrea
Abstract:: The use of zebrafish in behavioral neuroscience is rapidly growing. Zebrafish can be assessed for alterations in multiple behavioral endpoints, creating opportunities to use this powerful model to identify chemicals that alter behavioral phenotypes. To evaluate the utility of zebrafish for neurotoxicity research, we designed custom instrumentation to evaluate numerous...

A Performance Evaluation of In-Stream Hatchboxes and Streamside Incubators for Chinook Salmon

Creator:: Howell, Meghan Z.
Abstract:: Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...

Systematically evaluating the developmental toxicity of nanomaterials using the zebrafish model

Creator:: Edwards, Sabrina R.
Abstract:: As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...

Enzyme-Mediated Conversion of Glucolimnanthin to Bioherbicidal Breakdown Products

Creator:: Bratton, Daniel
Abstract:: The oilseed crop Limnanthes alba (white meadowfoam) is grown in Oregon. Methods were developed for the production of a liquid-based bioherbicide from meadowfoam seed meal (MSM). It was determined that glucosinolate-containing extracts of MSM can be combined with active-enzyme-containing liquid extracts of meadowfoam seed to form a fermented product rich...

Effects of Contemporary Forest Practices on Stream Nutrients, Temperature, and Periphyton in Small Headwater Streams

Creator:: Pimont, Cedric
Abstract:: Forest harvest practices can impact nutrient concentrations and stream temperatures, altering aquatic ecosystems. To better inform future sustainable forest resource management practices, quantifying the impact of current practices on water quality, particularly in headwater streams is important. In this study, I quantified monthly nitrate-nitrite (N) and orthophosphate (P) concentrations, 7-day...

Biochar as a cover for dairy manure lagoons: reducing odor and gas emissions while capturing nutrients

Creator:: Dougherty, Brian W.
Abstract:: Liquid manure lagoons are known to be sources of odor and environmentally damaging gas emissions. Land application of the manure slurry after storage can lead to detrimental nutrient runoff and leaching. Floating lagoon covers (biocovers) are one option for reducing emissions, but to date they have only been used to...

Using Acetylene as a Low-cost and Effective Methanogenesis Inhibitor in Single Chamber Microbial Electrolysis Cells

Creator:: Trujillo, Stephanie
Abstract:: Microbial electrolysis cells (MECs) for hydrogen production exhibit great advantages over many other biohydrogen production techniques in terms of versatility of substrate and hydrogen yield. However, hydrogen scavenging by methanogens put forward a great challenge to the application of the single chamber MECs when using mixed culture. Various strategies were...
