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...

Modeling sage-grouse habitat using a state-and-transition model

Creator:: Evers, Louisa
Abstract:: Habitat for wildlife species that depend on sagebrush ecosystems is of great management concern. Evaluating how management activities and climate change may affect the abundance of moderate and high-quality habitat necessitates the development of models that examine vegetation dynamics, but modeling tools for rangeland systems are limited. I developed state-and-transition...

Estimates of combining abilities, heterotic effects and phenotypic correlations among in-bred lines of beef cattle and their line-crosses

Creator:: Humes, Paul Edwin
Abstract:: The investigations were based on a complete diallel cross among three inbred lines of Hereford cattle. Records of Angus calves born during the same period were used to obtain more accurate estimates of environmental effects and to determine breed differences among the various traits included in the study. Estimates of...

The electrical conductivity of Atlantic type pyromagmas from Mount Etna, Sicily

Creator:: Mathews, Frank Samuel
Abstract:: The electrical conductivity of the pyromagmas from the Northeast Crater of Mount Etna, Sicily was measured over the temperature range 1032°C to 1071°C and over the frequency range 1 kHz to 400 kHz. Measurements were made using a four-terminal Wenner array in conjunction with a Wavetek Model 110B portable signal...

An economic evaluation of the range improvements administered by the Bureau of Land Management in the Vale District of Oregon

Creator:: Godfrey, E. Bruce
Abstract:: The federal government has spent considerable sums of money to rehabilitate range lands administered by the Bureau of Land Management (BLM). These investments have had varying effects on the production and utilization of forage on these lands. One of the most surprising results, according to BLM officials, of the investments...

An assessment of plant community structure, herbivory, soils, and state-and-transition theory on a winterfat (Krascheninnikovia lanata [Pursh] A.D.J. Meeuse & Smit) ecological site

Creator:: Matney, Casey A.
Abstract:: State-and-transition models (STMs) have been successfully used to describe ecological dynamics in woodlands, shrublands, grasslands, and several other ecosystems. Changes in vegetation and soil are measured to gauge and predict plant community dynamics within ecological states and transitions between alternative ecological states. Ecological states and their boundaries are defined by...

Genetic requirements for the assembly and cell-to-cell movement of the beet yellows virus

Creator:: Alzhanova, Dina
Abstract:: Beet yellows virus (BYV) is a filamentous, positive-strand RNA virus that belongs to the family Closteroviridae. BYV particles encapsidate a 15.5 kb RNA and posses complex polar architecture. A long virion body is formed by the major capsid protein(CP), whereas the minor capsid protein (CPm) assembles a short tail that...
