Specific Growth Rings to Which Douglas-fir Needles Are Attached: Site Variability

Creator:: Peterson, Alexandra M.
Abstract:: Stands of Douglas-fir (Pseudotsuga menziesii ssp. menziesii Mirb. (Franco)) near the Oregon Coast are showing signs of growth reduction from the foliar pathogen Phaeocryptopus gaeumannii that causes Swiss Needle Cast (SNC) disease. To better understand the mechanisms of needle drop through disease, and to learn the degree of variability in...

Simulated and Experimental Characteristics of Analysis Techniques for ZrCuAlNi/AlOx/Al Metal-Insulator-Metal Tunnel Diodes

Creator:: Tan, Cheng
Abstract:: This project examines the results of current-voltage conduction mechanism analysis techniques simulated under assumed conduction conditions. Thermionic emission and Fowler-Nordheim tunneling conditions are simulated and analyzed. The resulting plots show how devices behave under different condition mechanisms. The effects of different conduction mechanisms on the results of various analysis techniques...

Relationship between parasite load and diet quality in two desert bighorn sheep metapopulations in southern California

Creator:: Gibson, Sarah
Abstract:: The increased severity of unseasonal drought conditions in the American Southwest have resulted in herbivorous species, like the desert bighorn sheep (Ovis canadensis nelsoni), receiving lower quality forage in their diet at less reliable frequency. The Mojave Desert and the Peninsular Mountain ranges also contain large variations in elevation, which...

Screening for Viral Disease in the OSU Tomato Breeding Program

Creator:: Kershner, Alexandria C.
Abstract:: Disease control is a crucial aspect of plant breeding for researchers as well as commercial producers. After samples from OSU's tomato breeding program tested positive for Columnea latent viroid in a screen done by a private company, secondary testing was done by the USDA laboratory in Corvallis which suggested that...

Diet overlap by DNA metabarcoding of mule deer, elk, and cattle in ponderosa pine forest of eastern Oregon

Creator:: Faber, M. Kate
Abstract:: Millions of acres of rangeland in the western U.S. is shared habitat by elk (Cervus canadensis), mule deer (Odocoileus hemionus), and cattle (Bos taurus). Potential competition between these ungulates for the same forage species can be understood from their diet composition. I used DNA metabarcoding methods with trnL primers to...

Lateral Edge Connection and Withdrawal Capacity of Western Juniper

Creator:: Girod, Hayley E.
Abstract:: Western juniper (Juniperus occidentalis) is a “native invasive” tree species in Eastern Oregon. It is extremely good at finding and consuming water in arid climates, which makes it difficult for other plant species, especially sagebrush and grasses to survive. Sagebrush and grasses are necessary for the survival of the sage...

Toward an Optimal Working Distance for Hyperspectral Imaging of Wood

Creator:: Jayawickrama, Michelle T.
Abstract:: The forest products industry relies on the production of high-quality wood to satisfy consumer requirements. Improving wood quality requires an effective and inexpensive technique for measuring critical properties such as density and microfibril angle. An emerging technology known as near-infrared hyperspectral imaging (NIR HSI) essentially captures surface images of samples...

Flax as a Structural Reinforcement for Polymers

Creator:: McGeorge, Haley K.
Abstract:: Flax fibers are frequently used as a sustainable and recyclable reinforcement for composite materials in aesthetic applications (ex. car interiors). Flax fibers are biodegradable and can be sustainably harvested. Furthermore, the question of how to dispose of flax reinforced materials after the end of their lifetime can be solved in...

Exploring the Gut Microbiome of Captive Elephas maximus Experiencing Abnormal Feces

Creator:: Singh, Sehajvir
Abstract:: The gut microbiome of all mammals is composed of a diverse commune of microorganisms including bacteria, fungi, archaea, protozoa and viruses 1. Studies have shown a symbiotic relationship between the gut microbiome and host physiology, with there being implications in health and disease progression 2. In captive animals, there has...

Mixed-Conifer Stands of the Deschutes National Forest : A Brief History

Creator:: Rogan, Claire C.
Abstract:: In an effort to qualify the historical management and its effects on current stand structure, historical records, literature of the inter-mountain West, and current observations were utilized to paint a picture of the Deschutes National Forest. Stand data were collected for the Deschutes during the summers of 2009 and 2010....
