User Interface and Database for the Intuitive, Developmental And Research Oriented, Easy To Use, Affordable, And Low Volume (IDEAL) Bioreactor

Creator:: Litzinger, Jaelyn W.
Abstract:: Expensive pricing for laboratory bioreactors proves to be the main barrier-to-entry for lab-scale academic research. Most laboratory bioreactors are priced at $100K+ and require significant training to use, thereby limiting their accessibility. The IDEAL (Intuitive, Developmental And Research Oriented, Easy To Use, Affordable, And Low Volume) Bioreactor aims to solve...

Development of a two-dimensional hydraulic model to evaluate sediment deposition after the Klamath dam removal

Creator:: Marx, Abigail
Abstract:: After over two decades of advocacy and planning, the four hydroelectric facilities on the Klamath River will be decommissioned and removed starting in 2023. Significant positive changes are expected to result, from reduced severity of Harmful Algal Blooms (HABs) to nearly a two-fold increase in accessible habitat for native salmonid...

Statistically Downscaled Precipitation Water Isotope Time Series at NEON Study Sites

Creator:: Spencer, Lindsey
Abstract:: The National Ecological Observatory Network (NEON) provides open access data products including sub-daily precipitation amounts and biweekly stable water isotope concentrations at sites across the United States. Stable water isotope (ẟ2H, ẟ18O) concentrations are often used in hydrometeorological studies and models, however the relatively infrequent biweekly sampling intervals of NEON...

Assessing Annelid Habitat Suitability in the Lower Klamath River Basin

Creator:: Corrigan, Rory
Abstract:: This study assessed suitability of annelid habitats under current baseflow conditions and evaluated the mobility of suitable annelid substrates under a 2-year peak flushing flow. Outputs from a 2020 Bureau of Reclamation SRH-2D model were combined with field measurements of annelid presence/absence and habitat variables including depth, velocity and d50,...

Baseline Characterization of the Oregon State University Ocean Sentinel Site: Characteristics of five flatfish species on the Central Oregon coast

Creator:: Clark, Caitlyn E.
Abstract:: This study is a preassessment of the ecological status of habitats and species potentially affected by wave energy device installation, focusing on five flatfish species. Butter sole (Isopsetta isolepis), English sole (Parophrys vetulus), Sand sole (Psettichthys melanostictus), Pacific sanddab (Citharichthys sordidus), and Speckled sanddab (Citharichthys stigmaeus) were collected bimonthly from...

Error Propagation in Sap Flow Measurements Using the Heat Ratio Method

Creator:: Miller, Jackson T.
Abstract:: Accurate estimation of the amount of water used by trees is important for a variety of agricultural applications. There are several current methodologies for measuring sap flow and water use in trees, however the heat ratio method has been identified as the ideal due to its ability to measure low...

Predicting Watershed Characteristics Using Bacterial DNA

Creator:: Chadwick, Jessica A.
Abstract:: This study was conducted to determine if bacterial DNA present streams could be used to predict upstream watershed characteristics. Previous studies have found that bacterial composition in soil is influenced by land use. It was hypothesized that if the bacteria present in a stream is known that it can be...

A Comparative Analysis of Automated and Time-Integrated Sediment Samplers

Creator:: Babb, Arden I.
Abstract:: This study was conducted to determine if a time-integrated Phillips sampler was able to estimate sediment yield when compared to a reference produced by an automated sampler. Time-integrated samplers are easier to use, more cost effective, and can withstand storm events better than automated samplers, but are not designed to...

Occurrence of beaver (Castor canadensis) in volcanically disturbed lentic habitat

Creator:: Smith, Sierra L.
Abstract:: This study investigates the occurrence of beaver (Castor canadensis) in lentic habitat (lakes and ponds) near Mount St. Helens in Washington, 40 years after the 1980 eruption. At the coarse spatial scale, I surveyed lakes for sign of beaver establishment (lodge or den) across multiple volcanic disturbance zones. At a...

Tradeoffs and Preferences between Flood Mitigation Measures

Creator:: Byron, Elizabeth G.
Abstract:: Floods remain the world’s most destructive natural hazard, despite centuries of efforts to minimize losses. Understanding public preferences for flood mitigation measures, and the impacts of these measures, is key to minimizing flood-induced losses. This study quantified tradeoffs between flood mitigation measures and determined factors that influence public preferences for...
