Investigating physical drivers of phytoplankton bloom initiation in the Northern Gulf of Alaska

Creator:: Ballantine, Kaleigh
Abstract:: The spring bloom is a key oceanic phenomenon in the Northern Gulf of Alaska (NGA), where it supports the regional ecosystem, fisheries, and CO2 sequestration. Despite its significance, mechanisms that trigger NGA blooms are still debated, largely due to a lack of sufficient data from late winter through spring. New...

Microbial Abundance and Community Analysis in Devil’s Hole, Harrington Sound, Bermuda

Creator:: Denman, Carmen C.
Abstract:: Microbial activity within elevated CO2 and oxygen depleted environments changes with density driven stratification overturn in the seasonally anoxic region of Devil’s Hole, Bermuda. The temperature gradient developed during the summer months creates a natural laboratory to study bacterial and virus population density and microbial community dynamics in the anoxic...

The Role of the Academic Advisor as a Support Person for Student-Athletes in Higher Education

Creator:: Phillips, Rachel (Rachel Lynne)
Abstract:: Despite policies implemented by the NCAA with the intention of increasing student-athlete academic success and persistence to graduation, student-athlete graduation rates still remain low, with only 65% of student-athletes receiving their college degree. Certain non- cognitive variables, including the availability of a strong support person, have been shown predict persistence...

Weighing the Benefits of Returning Fire to the Landscape: Strategic Fire Management Workloads

Creator:: Goodwin, Ian
Abstract:: The accumulation of fuels in fire prone landscapes, and changing climatic conditions, have resulted in increasingly volatile fire behaviors. As a result, social and operational risk, management expenditures, and budgetary requirements for responsible agencies are increasing. The United States Forest Service (USFS) manages 193 million acres across the United States...

0An assessment of the oviposition behavior of spotted-wing drosophila (Drosophila suzukii) in the presence of a novel management tool in Pinot noir grapes

Creator:: Blood, Rachel A.
Abstract:: Spotted-wing drosophila (SWD, Drosophila suzukii) is an invasive fruit fly species native of Southeast Asia. In vineyards, SWD lays eggs in damaged and intact fruit of the most soft-skinned varieties, and feeds on damaged fruits during the harvest period. Feeding and oviposition activities increase the likelihood of vectoring spoilage bacteria,...

Presence and pathogenicity of Fusarium and Verticillium species in commercial red radish (Raphanus sativus) seed production in the Willamette Valley of Oregon

Creator:: Bomberger, Rachel A.
Abstract:: Commercial radish seed producers in the Willamette Valley of Oregon have observed a late season wilt in their seed fields. Twenty-two fields were surveyed for wilt in the Willamette Valley during June through August 2012 and 2013. Plants exhibiting wilt symptoms were collected from the fields and examined for vascular...

Response of Soil Microbially Mediated Nutrient Cycling and Community Structure to Timber Harvest in the Pacific Northwest

Creator:: Danielson, Rachel E.
Abstract:: Forest harvest persists as one of the most globally important industries, and crucially provides raw wood products for both building and fuel materials. Mechanistically complex abiotic and biotic processes curb ecosystem recovery following timber harvest and it is of great importance to understand the effects of this practice on biogeochemical...

Plant community dynamics in remnant and restored Willamette Valley wetland prairies

Creator:: Schwindt, Rachel A.
Abstract:: Invasion by exotic species can pose a major challenge for developing native plant communities in wetland restoration projects. Often native plant communities do not develop as anticipated in restored wetlands due to colonization by exotic species that dominate the native plant community. Despite the time and expense to restore wetlands,...

Perceived Barriers to Accessing Mental Healthcare to Student Veterans

Creator:: Haney, Rachel M.
Abstract:: The goal of this research was to analyze what different types of perceived barriers affect student veterans' access to mental healthcare services. Previous research has shown that veterans who return from combat and later attend universities are not receiving adequate mental healthcare for mental health problems, including Post-Traumatic Stress Disorder...

Advanced Solvent Purification Process Design using Aspen HYSYS and Feasibility Studies

Creator:: Meeuwsen, Rachel M.
Abstract:: High purity isopropyl alcohol (IPA) is utilized in silicon wafer manufacturing in cleaning and drying processes. With the ever-decreasing die size, there is an increased need for even higher purity chemicals. This process was designed to further purify a 250,000 lbs/month stream high purity isopropyl alcohol stream for use in...
