Sugar pine and western white pine are widely distributed, economically valuable, and ecologically important native tree species in North America. However, white pine blister rust (WPBR), caused by a non-native fungal pathogen, Cronartium ribicola J.C. Fisch. in Rabh., has substantially affected populations of these species. Cronartium is an obligate parasite,...
Wireless technologies advance rapidly in the recent time. The maJor initiative is the realization of the third generation wireless network that provides high bandwidth access to digital data on the Internet. Moreover, recent improvements in computer and embedded systems have enabled portable devices with sufficiently high computing capability.
The combination...
This is an IRB-exempt thesis exploring place relationship in the valley of Lake Creek, Oregon, at Triangle Lake. An interdisciplinary ethnography of place, it involves a synthesis of archaeological, historical, and ethnographic literature; an analysis of nineteenth-century Coos, Alseya (Alsea), and Kalapuya myth-texts from Native oral tradition; a history of...
This capstone project is expected to be published by United States Department of Agriculture Animal and Plant Health Inspection Service Wildlife Services (USDA APHIS WS) as part of a technical series guide available to the public through the website (https://www.aphis.usda.gov/aphis/ourfocus/wildlifedamage/sa_reports/ct_wildlife+damage+management+technical+series). USDA APHIS WS is responsible for mitigating human-wildlife conflict and...
From 1914-1918 the world experienced humanity’s ultimate affirmation of malice on scales scant seen in the centuries before. The Great War wrought terror on an industrial scale, throwing men headlong unto landscapes rent low by fire and steel. Our collective unconscious image of the war does well to demonstrate this....
The surgical standard of care to partially restore grasping function after a traumatic spinal cord injury is a reconstructive tendon transfer-surgery that connects all four finger flexors to an expendable wrist extensor. While restorative, this surgery has a fundamental problem; the movement of all four fingers flexors is directly coupled,...
Sperm acrosome associated 3 protein (SPACA3) is a unique, intra-acrosomal, conventional-type lysozyme-like protein of mammalian spermatozoa. SPACA3 is present in all stages of ovarian follicles and is localized to granulosa cells and ooplasma in humans, mice, cows, dogs, and cats. The objective of this study was to determine if equine...
The purpose of this thesis was to quantify sperm acrosome associated 3 (SPACA3) protein expression in the ovaries of young (3.0±0.9 months, n=11) and adult (10.4±2.8 months, n=11) queens. It was hypothesized that SPACA3 expression would not differ between age groups. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded feline ovarian sections...

How the direct and indirect effects of species interactions cascade to affect community structure, functioning, and stability is a fundamental question in ecology. In temperate kelp forests, species interactions, in conjunction with environmental processes, produce rich spatiotemporal dynamics.
Arguably the most dramatic of these are abrupt shifts in community state,...
Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
The majority of teachers in the state of Oregon are White, prompting the state’s legislative bodies to explore and create ways to increase racial diversity in the profession. Contextually, both state level mandates and national accreditation bodies have attempted to address the lack of diversity amongst teachers in the K-12...
Close reading has long been favored as an interpretative framework within those classrooms commonly united under the umbrella of English studies. This thesis explores the role of a particular brand of close reading—one often assessed through text-dependent questions—and critiques its centrality within assessment and curriculum materials for the AP Program...
As a child of two Khmer Rouge refugees, the Khmer Rouge genocide serves as the prologue of my family’s story. The Khmer Rouge genocide took place in Cambodia in 1975-1979 after a successful coup led by the Communist Party of Kampuchea (CPK) (Dy 2007, 2). In an attempt to create...
A substantial fraction of estuarine tidal wetlands have been lost to development or other human uses in the Pacific Northwest since the 1800s. Wetland restoration, typically through tidal re-connection, can restore normal tidal hydrology to these areas and improve estuarine capacity to support ecosystem functions and services. Restoration may initiate...
Wild horse and burro management has been a controversial topic over the past several decades, since the passing of the Wild and Free-Roaming Horses and Burro Act of 1971, as federal land management agencies attempt to manage wild horses and burros in a way that supports natural ecological balance. In...
The Internet of Things (IoT) paradigm brought an ever-increasing dependence on low-power devices to collect sensor data and transmit that information to the cloud, placing greater demand on connectivity and lifespan. In response, rapid worldwide innovation demonstrates the trade-offs in processing, communication, and energy consumption with diverse approaches to low-power...
Mathematics Graduate Student Instructors (GSIs) have a significant impact on the teaching and learning of mathematics in post-secondary contexts through their work as instructors of record, tutors, graders, and recitation, laboratory, or discussion leaders for mathematics courses. Perhaps more importantly, GSIs are future teachers of mathematics: more than 60 percent...
The goal of my thesis is to (a) help reveal to the Corvallis community who comprises this local population and (b) to share with local resource agencies what potential gaps are present from the perspectives of the homeless individuals who call Corvallis home. We interviewed eight (8) individuals who have...
The current American free-roaming horse (Equus caballus) population far exceeds the appropriate population limit set by the Bureau of Land Management (BLM) to preserve resources on public lands. Several techniques have been tested to assist in decreasing repopulation rates. The purpose of the present study was to analyze two contraceptive...
