Assessing Petal-cutting bees (Megachile sp.) usage of Clarkia amoena (Onagraceae) petals through the lens of iNaturalist and a Garden Experiment

Creator:: Mead, Mallory
Abstract:: Farewell-to-spring (Clarkia amoena) is native to the Pacific Northwest and commonly found in gardens, due to its aesthetic value and purported benefits to pollinators. Oregon and Washington are home to five subspecies of C. amoena, yet commercially available seed is limited to C. amoena ssp. lindleyi and C. amoena cultivars....

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...

Developing a hemp dihaploid protocol

Creator:: Murphy, Sean K.
Abstract:: Cannabis production has gained popularity over the last 10 years. There is a growing demand for true-to-type grain, fiber, and resin crops. Breeding for homozygous trait development with traditional methods can take as long as 8 years. With dihaploid breeding, homozygosity can be achieved in 2 generations saving breeders time...

Early Prediction of Student Performance using Neural Networks: An exploratory study on the efficacy of a neural network model at predicting students’ final grades in a flipped classroom environment

Creator:: Bailey, Derrick
Abstract:: With the unique conceptual and mathematical backgrounds of every introductory physics student, there is no way to design a rigid curriculum that anticipates and meets every student’s needs. We can employ machine learning to explore the correlations that exist in the voluminous data from educational settings. That is, institutional, gradebook,...

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...

Bacterial seed endophytes of Douglas-fir (Pseudotsuga menziesii) and their potential to confer drought tolerance

Creator:: Hatwal, Shikhar
Abstract:: Bacterial endophytes have the potential to confer benefits to Douglas-fir ( Pseudotsuga menziesii ), for instance drought tolerance. Bacterial endophytes originating from seeds are especially important. This is because seed endophytes are more likely to be the first endophytes to get established within the young host plant. The goals of...

Methods of Reproductive Control in Domestic and Free-Roaming Horses and the Behavioral Implications

Creator:: Negretti, Christina L.
Abstract:: The current American free-roaming horse (Equus caballus) population far exceeds the appropriate population limit set by the Bureau of Land Management (BLM) to preserve resources on public lands. Several techniques have been tested to assist in decreasing repopulation rates. The purpose of the present study was to analyze two contraceptive...

Biotic and Abiotic Factors Affecting the Presence of Beneficial Insects on Oregon Christmas Tree Farms

Creator:: Cain, Alyssa B.
Abstract:: Beneficial insects could provide valuable pest control services on Oregon Christmas tree farms, but a limited amount of data exist that quantifies the type and abundance of beneficial insects on farms. This study surveyed beneficial insects on two farms that differed in their management strategies as well as other abiotic...
