Physiological characterization of the mixotrophic dinoflagellate Amphidinium carterae

Creator:: Tornberg, Emma C.
Abstract:: Marine primary production can be modeled and estimated using remotely-observable physiological signatures such as chlorophyll and carbon. Current models are based on strict physiological relationships based on photoautotrophic phytoplankton, and discrepancies between modeled and in situ data may stem from unaccounted-for physiological deviations from photoautotrophy. Mixotrophic phytoplankton can obtain energy...

The Role of Arabidopsis RNA-Dependent RNA Polymerase Genes 3, 4 and 5 in Antiviral Defense

Creator:: Lowery, Nicholas C.
Abstract:: RNA silencing plays a critical role in plant defense against viral infection. Plants use virusderived small interfering RNA to target and silence invading viruses. The antiviral silencing pathway can be broken down into three conceptual stages: initiation, amplification, and systemic movement. The molecular mechanisms of silencing initiation are not well...

Impact of pre-fermentation maceration techniques on yeast populations and color of Pinot noir wine

Creator:: Zook, Molly L.
Abstract:: The quality of red wine is primarily determined by the flavor, aroma, and color. A common wine making technique used to improve these characteristics is the pre-‐fermentation maceration. In this study two pre-fermentation maceration techniques were used, one was a traditional cold soak and the second involved addition of dry...

Stress and Learning in Larval Zebrafish (Danio rerio)

Creator:: Moussaoui, Bushra
Abstract:: In this study, we characterize the behavioral response of larval zebrafish (Danio rerio) to the noxious chemical allyl isothiocyanate (AITC), an agonist of the nociceptive TRPA1 ion channel, and utilize AITC as an aversive stimulus in an associative learning paradigm. We find that larvae exposed to AITC in both a...

Old Crops in a New World: Bringing Andean Tuber Crops to the Pacific Northwest

Creator:: Reers, Michelle
Abstract:: Though currently relatively unknown outside Latin America, Andean root and tuber crops are rapidly gaining interest elsewhere. Tubers are a major food and important sources of nutrition in South America and have potential in countries outside their center of origin. We conducted a two-part study on oca (Oxalis tuberosa), mashua...

Early competitive environments differentially influence stress axis responses in sympatric, ecologically similar songbirds

Creator:: Hardt, Braelei M.
Abstract:: 1. Early competitive environments can shape the development of offspring across taxa. For example, competition for food can have downstream effects on offspring phenotypes and fitness; however, little is known about how early competition influences the development of the hypothalamic-pituitary axis and its potential tradeoff with growth. Because baseline and...

Estuaries in Motion : Teaching Estuarine Flow Concepts through Video

Creator:: Cameron, Marina R.
Abstract:: A short (approximately 8 minute) video was created to explain key concepts in estuarine flow and numerical modeling of estuaries for high school students. Animation, real picture videography, and numerical model outputs were used to illustrate how scientists use physics and physics models to understand how flow in an estuary...

A Dysfunctional System: Policy Recommendations for the Adult (18-65) Homeless and Severely Mentally Ill Population in Oregon

Creator:: Miller, Donielle F.
Abstract:: Adults with severe and persistent mental illness (SPMI) are overrepresented in the homeless population, and Oregon’s homeless population has expanded in recent years. In the 1950s, the mentally ill were moved out of the state hospitals and into the community. However, due to a lack of support services in the...

Variation of phenolics in anthocyanin- and nonanthocyanin- fruit tomatoes

Creator:: Dalotto, Todd F.
Abstract:: Phenolic compounds are known to have biological activity with beneficial effects on human health. Fruit of cultivated tomatoes (Solanum lycopersicum L.) are a major source of phenolics in the U.S. diet because this crop is the second most consumed vegetable per capita, but actual levels are low compared to other...

Adapting the Methylene Blue Sulfide Detection Method for Use in a Microfluidic in-situ Monitoring Device

Creator:: Monares, Shane W.
Abstract:: Sulfide is an important species to measure in environmental water samples. The spectrophotometric detection method for reduced sulfur species (sulfide) based on generation of methylene blue was adapted to work in an apparatus utilizing microfluidic PDMS mixing and observation cells with flow channels in the 100 μm range. The benefits...
