Monitoring Onion Thrips Response to Insecticide Agri-Mek SC in the Treasure Valley of Eastern Oregon and Western Idaho

Creator:: Flores Elizondo, Dennet
Abstract:: Onion thrips (Thrips tabaci) are pests found in onion fields of the Treasure Valley, which is located in Eastern Oregon and Western Idaho. Thrips cause damage to this high value crop by feeding on the onion’s extracellular fluid, making photosynthesis more difficult to occur. The feeding from the thrips can...

Utilization of structure-activity-relationship for predicting chemical toxicity in primary human lung cells

Creator:: Galbreath, Amanda
Abstract:: There is a growing need to establish alternative approaches for assessing hazard from chemical exposure compared to the traditional method of animal testing. Approaches that relate chemical structure to biological activity are gaining acceptance in the field as in silico methods for characterizing and predicting chemical toxicity. In this study,...

Development of a diagnostic assay for Phytophthora ramorum lineage detection

Creator:: Roig-Paul, Mireia
Abstract:: Phytophthora ramorum is the causal agent of Sudden Oak Death (SOD), which is an economically and environmentally important disease causing up to 80% mortality of tanoaks in Pacific Northwest coastal forests (LeBoldus et al., 2022). There are currently four clonal lineages in the United States and Europe, named North America...

Exploring the Growth Habits of Sweetpotatoes (Ipomoea batatas) in the Willamette Valley of Western Oregon

Creator:: Epps, Charlotte
Abstract:: Sweetpotatoes are a highly nutritious staple crop, playing an important role in global nutritional security. Although the majority of research in the United States (U.S.) focuses on the cultivation of the storage roots, both the leaves and roots are edible. Sweetpotatoes are indigenous to the Andes Region of South America;...

Ovarian protein hormones as biomarkers of fertility in dairy cows – Is it an acceptable model to predict infertility in dairy breeds?

Creator:: Lopez, Ruben
Abstract:: Female dairy cattle are particularly prone to infertility/subfertility with pregnancy rates ranging as low as 27% to a high 40%. On average it takes more than one breeding/insemination event for dairy cattle to become pregnant. This results in a loss of the number of calves a female would have per...

Anti-Mullerian Hormone (AMH) Levels Are Reduced by Age, But Do Not Correlate With Pregnancy In Timed-Mated Rhesus Monkey Females (Macaca mulatta)

Creator:: Roth, Maggie
Abstract:: Infertility is an issue affecting millions of women across the globe, yet the causes are not fully understood, and treatment options are often ineffective. The evaluation of reproductive hormones has been a common tool used by fertility clinics as a way to predict the ovarian response to treatment and gain...

Monitoring Resistance in Onion Thrips to Insecticides, Lannate® and Exirel®, in the Treasure Valley of Eastern Oregon and Southwestern Idaho

Creator:: Sanchez, Kevin
Abstract:: To evaluate and monitor insecticide resistance in onion thrips Thrips tabaci on onion (Allium cepa), we conducted a study using three field populations in the Treasure Valley of eastern Oregon and southwestern Idaho using the insecticides Lannate (methomyl) and Exirel (cyantraniliprole). To evaluate these two insecticides, biological assays were conducted...

Toxicity Screening of Polycyclic Aromatic Hydrocarbons (PAHs) in Primary Human Bronchial Epithelial Cells

Creator:: Amador, Samantha B.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a known class of chemicals that are linked to a multitude of adverse health outcomes. There are over 1,500 of these chemicals across various families and subgroups. 16 of these PAHs, known as parent PAHs, are identified by the EPA for focused risk assessment within...

Soil Fire Ecology: Assessing Wildfire Severity Impacts on Pacific Northwest Forest Soil Carbon

Creator:: Fleetwood, Shea
Abstract:: Pacific Northwest temperate rainforests are anticipated to experience increasingly frequent and severe wildfires in the foreseeable future due to climate change, increased fuel loads, and deforestation. Soil, underlying these forests, is the largest terrestrial carbon (“C”) reservoir. Fire disturbance influences soil C persistence, the timeframe and magnitude of which remain...

MatTek™ EpiIntestinal™ a 3D Small Intestine Epithelial Cell Culture Model For In Vitro Screening in Dietary Chemopreventive Agents

Creator:: Raymundo, Wilfrido E.
Abstract:: Testing the many potential chemoprevention agents from dietary sources in animal or human models is expensive and takes a long time. In vitro models can be useful for screening the right compounds to use in larger studies. We tested the MatTek™ EpiIntestinal™ small intestine epithelial 3D cell culture model for...

VOC Emisions and Categorization in Axenic Growth Conditions by Phaeodactylum tricornutum

Creator:: Thompson, Douglas A.
Abstract:: Volatile organic compounds (VOCs) play an integral role in climate change and as a carbon source for organisms living in a marine environment. These compounds have many sources, but the impacts of biogenically produced VOCs is not fully known. Phaeodactylum tricornutum was studied under axenic ideal growth conditions to determine...

Effects of Selenium Supplementation During Different Trimesters of Pregnancy on Total and Vibrio coralliilyticus Specific IgM Antibody Concentrations in Beef Cows at Parturition

Creator:: Zurita Cruz, Cindy
Abstract:: Background: The immune response to microbial infections is compromised in beef cattle at parturition. Innate and adaptive immunoglobulin M (IgM) serve as initial antibodies during microbial infection before the generation of adaptive immunoglobulin G (IgG). Selenium (Se) is an essential micronutrient required by all mammals, which can improve immune responses...

Invest in Vegetables: A Cost and Benefit Analysis of Container Grown Roma Tomatoes (Solanum lycopersicum cv. ‘Roma’) and Italian Basil (Ocimum basilicum cv. ‘Italian’)

Creator:: Spofford, Tyler S.
Abstract:: The COVID-19 pandemic highlighted disparities in land access and food security. Research has shown that access to gardening reduces financial burdens on low-income households. Compared to homeowners, individuals and families in rental housing face added barriers to vegetable gardening and growing food. These barriers include rental housing regulations and the...

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...

Detrital Input and Removal Treatment (DIRT) Network Soil Analysis in the UMBS Michigan Field Site

Creator:: Bushyhead, Coryn N.
Abstract:: Soil contains approximately 75% of the carbon pool on land - three times more than the amount stored in living plants and animals (Schlesinger 1999). Therefore, soils play a major role in maintaining a balanced global carbon cycle. Models of the soil carbon ecosystem assume a strong relationship between organic...

Endometrial Inflammatory Cytokine Expression in Postpartum Beef Heifers Following Platelet Rich Plasma Treatment

Creator:: Perez, Victor O.
Abstract:: Background: Uterine inflammation (e.g., endometritis) causes negative economic effects in the beef industry by reducing reproductive performance. Current treatments for endometritis in beef cattle involve hormones and antibiotics, which can be expensive and are often ineffective. The endometrial immune response regulates the release of cytokines and chemokines in response to...

Changes in Otolith Shape in Juvenile Chinook Salmon in Different Hatchery Rearing Conditions

Creator:: Ehrke, Melissa A.
Abstract:: The decline of the Chinook Salmon has been a mystery of recent years due to their decline. It has been speculated that wild origin salmon have more vigor and survivability than hatchery reared fish. This is thought to be due to rearing conditions, possibly affecting sensory organ development. The sensory...

A Performance Evaluation of In-Stream Hatchboxes and Streamside Incubators for Chinook Salmon

Creator:: Howell, Meghan Z.
Abstract:: Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...
