The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate.
The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...
Based on current trends both pesticide and plastic production are expected to continue to rise in the coming decade. A growing global population coupled with the effects of climate change are the main drivers of increased pesticide use. Throughout this dissertation pesticides refer to herbicides, fungicides, and insecticides. Plastic production...
The purpose of this study is to investigate the use of recombinant lignin degrading enzyme, maganese peroxidise (rMnP), to detoxify inhibitors for theoptimization of ethanol production from lignocellulosic biomass. The negative effects of inhibitors: vanillin, furfural, hydroxymethylfurfural, and syringaldehyde on Saccharomyces cerevisiae and Pichia pastoris yeast cell growth in revealed...
The clean label movement is a persistent, consumer-driven trend that has shifted consumer preferences in favor of foods considered to be more natural. Although lacking legal definitions in food labeling, the terms “natural” and “clean label” are generally used to characterize foods that have short, minimal ingredient lists containing simple...
Over 470 dams have been removed in the United States, and a significant increase in dam removals has
occurred since the early 1990s. The aging of dams is often cited as the primary factor influencing removals;
as dams surpass their functional life span, safety hazards, economic costs, and environmental concerns...
The giant hairy desert scorpion, Hadrurus arizonensis, is a long-lived species
of North American scorpion that is presented here as an important model for research
in mating systems evolution and sexual selection. Many behaviors found in this
species were undocumented and are described here for the first time. This thesis...
The social sciences have the capacity to contribute to natural resource management through investigations of human dynamics associated with the environment. Sense of place (SOP), the formed relationships between an individual and the environment, has been considered a fundamental aspect of human well-being and can contribute to more holistic understanding...

Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...
Vibrio cholerae is the causative agent of cholera, a serious diarrheal disease in developing countries. V. cholerae has a unique redox driven respiration-linked sodium pump, Na⁺ translocating NADH:quinone oxidoreductase (NQR). Several reports previously showed that NQR plays an important role in virulence, metabolism, and sodium homeostasis of V. cholerae. This...
There are many different organizations and agencies which share responsibility for educating the public about responsible use of aquatic and marine resources. However, organizations specifically focused on particular dimensions of water use, such as Oregon State Marine Board (OSMB), often face challenges when attempting to recruit teachers to implement educational...
The goal of this research is to understand factors influencing the use of TEK in
natural resource management collaborations between tribes and federal agencies. This includes what evidence exists that TEK is being used, what tribal factors influence the use of TEK, what agency factors influence the use of TEK,...
Wild turkeys (Meleagris gallopavo) were first successfully introduced into Oregon and Washington in the 1960s; the population has grown in size and expanded in distribution to a point where it provides an important recreational hunting opportunity in both states that generates significant funds for habitat conservation and contributes financially to...
The dominant narrative of Asian Americans in higher education is one of high achievement, success, and wellness. Dominant voices of white supremacy have primarily constructed this narrative. Asian Americans are regarded as the model minority or the dichotomous “model” while simultaneously maintaining “minority” status. This study centers on seven Asian...
