Associations Between Crested Wheatgrass and Native Vegetation in Southeastern Oregon : An Investigation of Co-establishment, Environment, Seeding History, and Livestock management

Creator:: Nafus, Aleta M.
Abstract:: Crested wheatgrass (Agropyron cristatum [L] Gaertm), an introduced bunchgrass, has been seeded on over 5 million hectares of degraded rangeland in western North America because it establishes more readily than native bunchgrasses. Because crested wheatgrass stands are associated with native species displacement and low biological diversity, there is substantial interest...

Understory vegetation response and nitrogen cycling following cutting of western juniper

Creator:: Bates, Jonathan D.
Abstract:: Since the late 1880's western juniper has expanded in range and increased in density in sagebrush-bunchgrass, riparian, and forested plant communities of the Pacific Northwest. Succession to western juniper woodland has been shown to reduce the productivity and diversity of the understory component, result in concentration of soil nutrients beneath...

Drivers of plant community dynamics in sagebrush steppe ecosystems : cattle grazing, heat and water stress

Creator:: Reisner, Michael D.
Abstract:: Sagebrush steppe ecosystems are one of the most widespread but endangered ecosystems in North America. A diverse array of human-related stressors has gradually compromised these ecosystems' resilience to disturbance and invasion by Bromus tectorum (cheatgrass). The role of the foundational shrub Artemisia as a driver of herbaceous community structure and...

Nutritional and managerial considerations for wintering beef cattle in the northern Great Basin

Creator:: Brandyberry, Steven D.
Abstract:: A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...

Molecular genetics of frost hardiness and cold acclimation in Solanum species

Creator:: Valverde, Roberto
Abstract:: Frost injury is one of the major factors limiting potato production in many parts of the world. It would be desirable to transfer the frost-tolerance traits from the hardy relatives to the cultivated potato, however, progress has been very slow. Since Solanum commersonii has been the major source of frost...

High resolution spectroscopy of sulfur trioxide and carbon suboxide

Creator:: Masiello, Tony
Abstract:: High resolution spectroscopy was used to study the properties of two simple polyatomic molecules, sulfur trioxide, SO₃, and carbon suboxide, C₃O₂. The fundamental modes and several hot bands of the ¹⁸O isotopic fonns of SO₃ (³²S¹⁸O₃ and ³⁴S¹⁸O₃) have been investigated using both infrared spectroscopy and coherent anti-Stokes Raman scattering...

A study of factors influencing the selection of vocational teacher education by undergraduate students at Oregon State University

Creator:: Toby, Tony Udo
Abstract:: The purpose of this study was to ascertain the factors which influenced undergraduate students in the School of Education at Oregon State University to select vocational teacher education as their major. Data were collected from 315 vocational, practical arts, and non-vocational undergraduate teacher education majors who were enrolled in teacher...

Just enough die-level functional test : optimizing IC test via machine learning and decision theory

Creator:: Fountain, Tony R.
Abstract:: This research explores the hypothesis that methods from decision theory and machine learning can be combined to provide practical solutions to current manufacturing control problems. This hypothesis is explored by developing an integrated approach to solving one manufacturing problem - the optimization of die-level functional test. An integrated circuit (IC)...
