Impact of biased movement on marine protected area effectiveness

Creator:: Rekow, James Alexander
Abstract:: Fish mobility affects the distribution of commercially caught fish species in marine protected areas (MPAs) and unprotected areas, which we will call fishing grounds (FGs). Previous theoretical findings predicted that highly mobile fish would benefit little if at all from protection in MPAs (Demartini 1993, Walters et al. 1999). However,...

Impact of Vitamin E Deficiency on Hepatic Gene Expression of CRAL_TRIO Family Proteins in a Premier Vertebrate Animal Model

Creator:: Watt, Alexander T.
Abstract:: Vitamin E (vitE) is a group of lipid-soluble antioxidants- of which alpha-tocopherol is the most biologically active and only form considered to be an essential nutrient. Through preferential binding and trafficking, the alpha-tocopherol transfer protein (α-TTP) regulates the concentration of vitE in the body. The impact of vitE deficiency on...

Evaluation of ECOSTRESS products for estimation of leaf and grape water stress for Southern Oregon vineyards

Creator:: Swafford Steffensen, Collen
Abstract:: Accurate estimation of water stress in vineyards could prove vital for optimizing irrigation and grape quality in a changing climate. The ECOsystem Spaceborne Thermal Radiometer Experiment on the Space Station (ECOSTRESS) offers potential to remotely sense vineyard water stress but lacks validation against in-field measurements in vineyards. In this study,...

Environmental DNA reveals cryptic parasite species and gives insight into their fish hosts

Creator:: Phillips, Kyle
Abstract:: Ceratonova shasta is a myxozoan fish parasite that impacts hatchery and wild populations of salmon and trout in the Pacific Northwest. Levels of the parasite in river water can be effectively monitored through direct filtration of parasite spores from water, extraction of total "environmental DNA" (eDNA), then quantitative polymerase chain...

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,...

The Kalispel Tribe of Indian’s Contemporary Usage of Traditional Foodways

Creator:: Hilborn, Alexander M.
Abstract:: Native American traditional foodways serve as one of the most important resources for indigenous communities because these resources provide a variety of non-physical cultural assets and health benefits to Native groups through the medium of food. The demolition of North America’s foodways through colonization has had adverse effects on indigenous...

The effects of interspecies interactions and environmental conditions on biomass accumulation of sessile organisms within Oregon’s rocky mid-intertidal habitats

Creator:: Carsh, Alexander C.
Abstract:: With changing climate conditions and human impacts on ecosystems becoming a big focus of study, it has become even more crucial to understand how our ecosystems work. Community structure within rocky intertidal habitats is governed by a mix of environmental conditions and species interactions. This project examined the effects of...

An investigation into the design and use of a mutual inductance type fluid level probe for use in liquid sodium systems

Creator:: Moore, Alexander
Abstract:: Level measurement in liquid sodium systems has been studied in the U.S.’s past during the 1970’s, but locally little was done to advance the subject until a resurgence of interest in the last few years. As a result, to create a functional continuous fluid level measurement probe for the OSU...

A Comparative Study of Non-Normal Distributions in Continuous Dropout

Creator:: Guyer, Alexander D.
Abstract:: Recent studies have shown that novel continuous dropout methods can be viewed as a Bayesian interpretation of model parameters, though most such studies have shown results using normal distributions. As the posterior distributions over neural network nodes and parameters are intractable, given that they are a result of artificial construction...

Optimizing Cancer Drug Treatment Models Using Process Dynamics

Creator:: Jones, Alexander R.
Abstract:: Cancer is currently the second leading cause of death in the United States and the sixth leading cause of death worldwide. Due to cancer’s variability in type, location, growth rates, and patient physiology, treatment models are based off of previous experimental and clinical work. This variability, however, can lead to...

Distance Estimation in Virtual Reality

Creator:: Alexander, Jonathan M.
Abstract:: Distance estimation is a key process for movement and spatial cognition. However, this process is hindered when navigating virtual environments in virtual reality (VR) due to the movement being exclusively visually simulated. In order to contribute to the understanding of how this hinderance effects our ability to estimate distances in...

Investigation of Glacier Dynamics During the Last Glacial Maximum at Tioga Pass, Yosemite National Park

Creator:: Laub, Alexander G.
Abstract:: Previous investigations of glacier dynamics at Tioga Pass during the Last Glacial Maximum (LGM) have produced different conclusions. A map of the LGM ice extent and flow direction (Alpha et al., 1987) illustrates a south-to-north direction of ice flow across the pass with little evidence to support this inference. Since...

Fast Exemplar-Based Style Transfer with Enhanced Artistic Control

Creator:: Appleton, Alexander
Abstract:: Exemplar-based style transfer techniques reimagine the content of a target image in the style of an exemplar image. Style transfer techniques that make use of patch-based synthesis copy sections of the exemplar to corresponding regions of the target, creating a new image in a patchwork manner. The artistic control one...

Machine Learning and Optimization Applications in Agriculture

Creator:: Molotkov, Alexander
Abstract:: The ever-increasing global population presents looming problems for the field of agriculture. Global food demand will, at some point, increase to the point where there is not enough crop-ready land to keep up. This creates an additional incentive, other than economics, for growers to increase their yield-per-acre and make sure...

Vacuum Testing of a Small Radioisotope Thermoelectric Generator

Creator:: Mieloszyk, Alexander J.
Abstract:: Radioisotope Power Systems (RPS’s) are a key element to NASA’s deep space exploration programs. As NASA looks towards new generations of smaller, modular spacecraft, appropriately smaller RPS’s will be needed. The Single General Purpose Heat Source Radioisotope Thermoelectric Generator (S-GPHS-RTG) has been developed to fill this role. The S-GPHS-RTG will...
