Honey Bees (Apis mellifera) and Agricultural Chemicals: Global to Micro Perspectives

Creator:: Bernert, Ann
Abstract:: Fungicide sensitivity of honey bee associated fungi Abstract - Honey bees are exposed to a wide range of pesticides while pollinating agricultural crops. These pesticides residues are found in beeswax, nectar and pollen in the hive. Some of the pesticides found are fungicides which are not generally considered harmful to...

Is Advection Important? An Examination of the Advective Dynamics of Sensible Heat and Their Influence onSubcanopy Carbon Fluxes in Heterogeneous Terrain

Creator:: Carrigg, Sean Stephen
Abstract:: Abstract Understanding small-scale bio-atmospheric interactions is becoming increasingly important as the global climate continues to change at breakneck speed. A theoretical model of the sensible heat budget of a forest is developed combining conservation equations and concepts from fluid dynamics. Budget components are computationally evaluated using micrometeorological data taken during...

Characterizing PM2.5 with Different Source Contributions

Creator:: Perez, Allison Mae S.
Abstract:: Ubiquitous fine particulate matter (PM2.5) exposures significantly impact global public health, yet little is known about the mechanisms causing these known adverse health effects. Oxidative stress due to PM2.5 associated chemical constituents, such as polycyclic aromatic hydrocarbons (PAHs), is a proposed possible mechanism for PM2.5 mediated health effects. Variations in...

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...

A Panel of Histone H3 Mutations to Investigate Centromere Maintenance and Gene Silencing

Creator:: Esposito, Madison L.
Abstract:: Modifications of histone tail amino acid residues are necessary for many reactions involving chromatin. These processes can produce transcriptionally active, euchromatic, or inactive, heterochromatic, segments of DNA. The formation and maintenance of facultative heterochromatin is critical for the proper growth and development of many eukaryotes. Euchromatin can be changed into...

Enzyme-Mediated Conversion of Glucolimnanthin to Bioherbicidal Breakdown Products

Creator:: Bratton, Daniel
Abstract:: The oilseed crop Limnanthes alba (white meadowfoam) is grown in Oregon. Methods were developed for the production of a liquid-based bioherbicide from meadowfoam seed meal (MSM). It was determined that glucosinolate-containing extracts of MSM can be combined with active-enzyme-containing liquid extracts of meadowfoam seed to form a fermented product rich...

Characterization of Selective Knockout of Thioredoxin Reductase-1 (TR1) in Mouse Melanocytes In Vivo

Creator:: Wyant, Mark B.
Abstract:: Vitiligo is a disease characterized by depigmented patches of skin. The disease is known to involve the loss of melanocytes in the basal layer of the skin in affected areas, but the underlying mechanisms are unknown. Recent evidence suggests oxidative stress and disruptions to antioxidant pathways contribute to an autoimmune...

Effects of Contemporary Forest Practices on Stream Nutrients, Temperature, and Periphyton in Small Headwater Streams

Creator:: Pimont, Cedric
Abstract:: Forest harvest practices can impact nutrient concentrations and stream temperatures, altering aquatic ecosystems. To better inform future sustainable forest resource management practices, quantifying the impact of current practices on water quality, particularly in headwater streams is important. In this study, I quantified monthly nitrate-nitrite (N) and orthophosphate (P) concentrations, 7-day...

Guinea pig model of mild hyperandrogenemia – is it a suitable model for women with polycystic ovary syndrome (PCOS)? A pilot study

Creator:: Barboza Sagrero, Juriana E.
Abstract:: Polycystic Ovary Syndrome (PCOS) is an idiopathic disorder prevalent in ~5-10% of reproductive-aged women. In PCOS women who become pregnant, many experience complications including increased susceptibility of having a miscarriage, high blood pressure, and gestational diabetes, among others. Additionally, exposure to PCOS may have transgenerational impacts: offspring may be at...
