Tracking the Range Expansion of a Native Bee, the Squash Bee, Eucera (Peponapis) pruinosa; (Hymenoptera: Apidae) in Oregon using Community Science

Creator:: Jones, Miranda L.
Abstract:: The foraging distance of bees has been intensely studied. In contrast, little is known about the factors that determine bee dispersal distance, especially on large spatial scales. Eucera (Peponapis) pruinosa is a wild ground nesting bee that exclusively collects pollen from squash in the genus Cucurbita. Although the bee occurs...

Terra Cubes Design Final Technical Report: Design of a Modular Bioretention System for Nitrate, Phosphate and Herbicide Treatment

Creator:: Evans, Lucas, Larson, Lars, Debell, Thomas, and Dunstan, Nicholas
Abstract:: Plant nurseries comprise the largest agricultural sector in Oregon at nearly $1 billion per year. Even at this scale, individual nurseries and greenhouses do not have clear water quality standards set by the EPA. Watershed-level total maximum daily loads (TMDLs) have been set for excess nutrients and herbicides due to...

Quantifying dissipative beach and vegetated dune morphology with multiple aerial photography systems

Creator:: Conlin, Matthew P.
Abstract:: Sand dunes provide coastal communities critical protection from flooding and erosion, as well as a habitat for a range of species- some threatened or endangered. As such, it is of importance to develop a quantitative understanding of the processes through which these systems evolve at a variety of temporal and...

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;...

Streambed scour and redeposition behavior in streambed simulated culverts over an annual period

Creator:: Stewart, Anna
Abstract:: The objective of this study was to provide first order observations of bed level changes occurring in streambed simulated culverts throughout an annual period. To accomplish this, 30 culvert sites were selected in Oregon and Washington, and monitored over, at least, a 2 year period. Streambed scour and redeposition data...

The introduction of myxozoan parasites through the release of feeder goldfish (Carassius auratus)

Creator:: Karandashova, Sophia
Abstract:: Myxozoa have been found worldwide; these parasites infect a wide variety of hosts, but have been found most often in fish. Carassius auratus (goldfish), a popular aquarium fish and a widespread invasive species, have been identified as an intermediate host for several myxozoan species. Some myxozoan parasites are pathogenic and...

Effects of Oxidative Stress on Circadian Gene Expression during Aging

Creator:: Bonar, Tara
Abstract:: All organisms possess circadian clocks, which generate daily oscillations in clock controlled gene expression that regulate many essential biological functions in synchrony with the 24-hour light/dark cycles. When the genes that control the internal clock are weakened, accelerated aging symptoms are observed. Past research in Drosophila demonstrated that aging flies...

Full Text:: observed. Past research in Drosophila demonstrated that aging flies with disrupted clocks have higher

Tracking Competitive Season Training Load via TRIMP in a Collegiate Distance Runner : A Case Study

Creator:: Anderson, Morgan Jane
Abstract:: Objectively quantifying workload is challenging due to a variety of factors. One way to measure workload is by training impulse (TRIMP). TRIMP uses time in physiologically significant heart rate zones to quantify a workload for a given bout of physical activity. Tracking average workload over time can then be used...

Preliminary deployment and evaluation of geophone sensors for monitoring wave activity: GeoMoteShield

Creator:: Lathrop, Eve
Abstract:: This study focuses specifically on the investigation of a new, inexpensive geophone system and its application to monitor wave activity. Studies of seismic observations of coastal cliffs suggest that ground motions generated from local ocean waves may provide a surrogate to limited wave buoy data to quantify the wave contact...

Aluminum Tolerance of Winter Wheat

Creator:: Sadler, Cameron
Abstract:: Wheat is an important part of a healthy and balanced diet, requiring six servings per day to maintain a recommended 2000 Calorie intake (McRae, 2017). Because of this more land than almost any other kind of cereal is set aside for the purposes of growing wheat. To keep up with...
