Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:: Cummings, Brittany M.
Abstract:: Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...

Effect of metformin exposure on growth and photosynthetic performance in the unicellular freshwater chlorophyte, Chlorella vulgaris

Creator:: Cummings, Brittany M., Needoba, Joseph A., and Peterson, Tawyna D.
Abstract:: Many pharmaceuticals have negative effects on biota when released into the environment. For example, recent work has shown that the commonly prescribed antidiabetic drug, metformin (N,N-dimethylbiguanide), has endocrine disrupting effects on fish. However, effects of metformin on aquatic primary producers are poorly known. We exposed cultured isolates of a freshwater...

Is there no “I” in team? Potential bias in key informant interviews when asking individuals to represent a collective perspective

Creator:: Fleming, Whitney, King, Brittany, Robinson, Kerrick, Wade, Eric, Erickson, Brian, Delie, Jackie, de Ycaza, Ricardo, Trimbach, David, Spalding, Ana, and Biedenweg, Kelly
Abstract:: This paper sought to understand the extent to which, and how individuals use personal or collective language when asked to articulate sense of place from a collective perspective. Understanding a collective sense of place could illuminate place-based connections in natural resource industries, where it is as groups or as institutions...

Characterization of Two Aerobic Bacteria from Canada Goose Microflora by Whole Genome Sequence Analyses

Creator:: Larkin, Abigail M.
Abstract:: 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...

Comparison of Three Different Analyzers to Measure Canine Serum Progesterone

Creator:: Hisanaga, Trevor H.
Abstract:: The canine estrous cycle is unique compared to other domestic animal species. During estrus, serum progesterone concentrations ([P4]) rise two days prior to ovulation. In fact, the luteinization of pre-ovulatory follicles resulting in this initial increase in [P4] (1.5-2.5 ng/ml) cannot be temporally dissociated from the onset of the surge...

Ingestion of Microplastics in the Juvenile Black Rockfish (Sebastes melanops) from Oregon Coastal Sampling Sites

Creator:: Arnold, Madison A.
Abstract:: Microplastics (<5mm) are a ubiquitous environmental pollutant that have the potential to cause significant harm in many fish species. Therefore, understanding the quantities at which they are being consumed by living organisms is crucial for characterizing risk. There are currently gaps in the microplastic literature regarding microplastic data from finfish...

Into the Garden: Environmental Education and Resources for K-5

Creator:: Smith, Amira R.
Abstract:: 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...

Breeding Snap Beans for Organic Agriculture: Genomic Shifts under Different Agricultural Management Systems

Creator:: King, Ryan M.
Abstract:: Although the concept of breeding crops for organic agricultural systems has been around for decades, few studies have been reported for vegetable crops to quantify and compare how conventional and organic systems differ in their selection pressures on genotypes advancing through the breeding cycle; especially research utilizing modern sequencing capabilities....

Designing and Evaluating a User Interface for Multi-Robot Furniture

Creator:: Stoddard, Brett
Abstract:: A chair, once placed, will stay put until moved. Or will it? With the rise of technology being embeddable into everyday objects, what if that chair could move itself? Such robotic furniture has been featured in advertisements, art, and Human-Robot Interaction (HRI) research. Existing methods for operating robotic furniture have...
