Oregon has one of the five highest homeless occupancy rates in the U.S., according to the Annual Homeless Assessment Report (2021). Using the current governor of Oregon’s (Tina Kotek) plan to decrease homelessness, which focuses primarily on housing developments and strategies, this study will first examine the merits of permanent...
The Tertiary geologic evolution of the Oregon and Washington continental margin was molded by episodic periods of convergence between the Pacific oceanic plates and the North American plate. This margin is the site of a deep basin that is floored by Paleocene to lower Eocene oceanic crust and contains more...
This thesis examines food insecurity in Oregon among food bank users over the course of The Great Recession. Analyzing data from the Oregon Food Bank, this thesis tells the story of the change that the recession brought upon low-income families. In examining the regional differences in food insecurity, the local...
Hydraulic conductance of leaves (K[subscript leaf]) typically decreases with increasing water stress and recent studies have proposed different mechanisms responsible for decreasing K[subscript leaf]. We measured K[subscript leaf] concurrently with ultrasonic acoustic emissions (UAEs) in dehydrating leaves of several species to determine whether declining K[subscript leaf] was associated with xylem...
The black-footed ferret is a meso-predator within the Great Plains region of North America. Before the 1900s, black-footed ferret populations were self-sustaining in large ecological patches throughout the geographical range of the Great Plains. During the 1900s, various factors such as the systematic extermination of prairie dogs (the primary food...
The following taxonomic keys are adapted in part from the subgeneric and species descriptions and keys produced by McGinley (2003), Gibbs et al. (2013) and Gardner and Gibbs (2022). Additional identification information was provided by Jason Gibbs, Thilina Hettiarachchi (University of Manitoba), and Joel Gardner (Washington State University). While these...
People are increasingly staring at device screens which emit predominantly blue light. Because LED technology is relatively new, we do not know what effects blue light has on our long-term health. Blue light exposure leads to a dramatic decrease in longevity in Drosophila, thus this study aims to explore possible...

Dr. Patty Skinkis, Viticulture Extension Specialist & Associate Professor, OSU opens the newsletter with...
Many performance tuning tools for parallel software use visual representations of trace data to guide a developer towards code improvements. Most widely used visualization schemes, however, either omit useful information about time dependence of processor use, or include that information but do not scale well to long run times or...
The Goose Lake Basin, situated on the border of Oregon and California, USA, faces significant challenges from drought, wildfire, and other environmental stressors. This region hosts numerous endemic fish species such as the Goose Lake redband trout (Oncorhynchus mykiss newberri), Goose Lake lamprey (Entosphenus sp.), Goose Lake tui chub (Siphateles...
