Quantifying Marine Microplastic Ingestion in Black Rockfish (Sebastes melanops) on the Oregon Coast

Creator:: Laundry, Jordan G.
Abstract:: 1. To determine whether plastics are being ingested by black rockfish at three sites along the Oregon coast 2. To determine if there is a significant difference in rates of plastic ingestion between marine reserve locations and Newport location. 3. To quantify the extent of plastic ingestion and to identify...

Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

Creator:: Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
Abstract:: Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

Matrix Metalloproteinases as Plasma Indicators of Bovine Cystic Ovarian Disease

Creator:: Hentze, Kalina F., Younger, Kathryn G., and Menino, Alfred R., Jr.
Abstract:: Cystic ovarian disease (COD) is one of the main causes of infertility in dairy cattle and has a high economic impact on farmers. COD is caused by an endocrine imbalance within the hypothalamic-pituitary-ovarian axis which prevents the mature Graafian follicle from ovulating. The cause at the molecular level is not...

Associations Between Relocation and Seasonal Depression

Creator:: Morozov, Andrey A. and Kerr, David C. R.
Abstract:: Seasonal Affective Disorder (SAD) is a mood disorder that is characterized by depressive symptoms that onset and remit at the same times each year. Whereas few people (about 1%) experience problems severe enough to be labeled SAD, many people (estimates range from 30%-90%) may experience mild to moderate changes in...

Visual discrimination and memory of Enteroctopus dofleini, the Giant Pacific Octopus

Creator:: Boyle, Virinda R.
Abstract:: This study evaluated the memory and visual discrimination capabilities of Enteroctopus dofleini, the Giant Pacific Octopus. Octopuses have been known to have advance sensory capabilities and through this study we challenged our specimen to remember and actively choose a specific patterned jar based on a visual pattern and positive reinforcement....

Diet manipulations and color changes in Pisaster ochraceus

Creator:: Taylor, Katlyn R.
Abstract:: It has been observed and documented that Pisaster ochraceus has very striking colors, but the reasons behind the coloration are still unknown. Three coloration categories were determined and used for a feeding trial study to investigate the effects of diet on coloration in Pisaster ochraceus. This study involved 30 hand...

Defining the Reisz Transformation on the Unit Circle Using a Neumann Boundary Value Problem

Creator:: Nicolaysen, Cooper
Abstract:: This research was an attempt at gaining insight into the nature of the incompressibility conditions of the Navier-Stokes Equations on the Unit Circle. We realized the Riesz transformation is given in R^3 after taking the Fourier Transform of the Neumann Boundary Value problem, but this is not well defined on...

Toxicity and Mutagenicity of Polycyclic Aromatic Hydrocarbons in Contaminated Soils using Mammalian In Vitro Assay

Creator:: Luker, George W.
Abstract:: There exists a growing need to establish a better in vitro model for evaluating PAH toxicity and carcinogenicity and to improve assessments of risk to human health, especially to the complex mixtures that exist in the environment. Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants due to the incomplete combustion...

What Disrupts Cycles of Poverty? Examining the Effect of Family Background and Educational Attainment on Receiving Public Assistance with Multivariate Regression

Creator:: Vargas, Patricia I.
Abstract:: Understanding poverty as a state of being poor with regard to concretely being unable to meet basic needs such as water, food, clothes, shelter, and essential services (e.g., sanitation, health, and education), its concerted study in the United States not only stands tandem with constitutionally upheld values such as equality...

Effects of low zinc status and arsenic exposure in mice

Creator:: Chase, Tyler, Wong, Carmen P., and Ho, Emily
Abstract:: During fall term of 2015 and winter and spring term of 2016 I assisted in research within Dr. Emily Ho’s lab. The project that I assisted in looked at the effects of low zinc status and arsenic exposure in mice. Zinc is an essential micronutrient involved in numerous cellular processes...
