The West Fork Smith River, a 69 km2 watershed in the Coast Range of Oregon, is prone to short periods of very high water temperature in mid-summer due to a combination of human and natural influences. In the summers of 2003 and 2004 more than 400 juvenile coho salmon regularly...
In recent years, microRNA’s (miRNA’s) have emerged as important in regulating gene expression. Fluctuations in their levels are associated with the up or down-regulation of tumor-suppressor genes and oncogenes. Thus, the ability to visualize changes in miRNA is an important step in understanding cancer emergence and development. The Burrows group...
This study investigates the occurrence of beaver (Castor canadensis) in lentic habitat (lakes and ponds) near Mount St. Helens in Washington, 40 years after the 1980 eruption. At the coarse spatial scale, I surveyed lakes for sign of beaver establishment (lodge or den) across multiple volcanic disturbance zones. At a...
This thesis aims to address barriers that K-5 educators face when implementing environmental education in classrooms. An in-depth study of the history of environmental education in the United States identifies primary barriers and issues. Focusing specifically on garden education programs, six lesson plans for K-5 were created to address the...
The Canada goose (Branta canadensis) monogastric gut is proposed to contain aerobic spore-forming bacteria that produce non-toxin substances that may promote anti-inflammatory immune responses. It is hypothesized that the aerobic bacteria found in samples of Canada goose microflora could have probiotic effects in other avian species or used for commercial...
This study aimed to determine the efficacy of baking to reduce bacterial populations (an unknown contaminant or Salmonella) in cookie dough. Baking conditions (time and temperature parameters) were selected based on conditions commonly used in industry. The first study (Chapter 2), “Baking as Validation for Control of Coliform Counts in...
The purpose of this thesis is to propose swiveling behavior as a potential speech transitioning device and to discuss the methodology behind qualitative and quantitative analysis of swivels in relation to subjects’ partners. Due to the impacts of gaze and body orientation direction on speech transitioning, it is deduced that,...
The discovery of novel compounds with antibacterial properties continues to be critically important.3 One potential source of such compounds is the cryptic genome of fungi known to produce biologically active molecules. A kmt6 mutant of the cereal pathogen Fusarium graminearum was previously developed through a histone H3 lysine 27 methyltransferase...
Intimate partner violence is the systematic, intentional use of physical, emotional and/or sexual abuse that one person in a domestic relationship exerts over their partner in order to maintain power and control. In our society, we tend to focus on the external evidence of intimate partner violence such as the...
