An Exploration of the Ecological and Geographical Variability of Rhizopus microsporus Clinical and Environmental Isolates

Creator:: Stairs, Brandon S.
Abstract:: Rhizopus microsporus is a globally ubiquitous opportunistic human and plant pathogen that is known to harbor endosymbiotic bacteria. Differences between populations of clinical and environmental R. microsporus isolates have yet to be assessed on a global scale. Whole-genome sequence data were used to explore fungal biology and to assess potential...

Effects of Diversity and Spatial Separation of Pastures on Forage Production, Milk Yields, N Partitioning and Methane Emissions

Creator:: Carmona Flores, Lorena F.
Abstract:: Diverse pastures containing multiple species help extend the grazing season and reduce the reliance on one or two species to meet all the nutritional requirements of livestock. Planting pasture species in spatially separated adjacent strips can increase the proportion of pasture plants with certain agronomic and nutritional attributes such as...

Nitrogen fertilizer rate and application timing effects on growth and seed-oil yield of meadowfoam

Creator:: McGahuey, Michael L.
Abstract:: Meadowfoam has been identified as a potential oilseed crop for production on poorly drained soils in areas with cool, moist winters. The effects of N fertilizer on meadowfoam (Limnanthes alba Benth.) have been studied in Oregon and Maryland, but the results have not been consistent with respect to the effects...

Changing pastoral lifeways in the land where the horse was king : the effects of China's Grassland Contract Policy on Mongolian herders' attitudes towards grassland management and cooperation

Creator:: Conte, Thomas J.
Abstract:: This thesis explore the effects of China's Grassland Contract policy on sedentary and mobile Inner Mongolian pastoralists' attitudes towards cooperation, current grassland management practices, and the future viability of livestock herding in New Barag Right Banner, Inner Mongolia. Semi-structured interviews, a scaled survey instrument, and participant observation were carried out...

The role of plastic mulch as a water conservation practice for desert oasis communities of Northern China

Creator:: Ingman, Mark Christian
Abstract:: China's Minqin Oasis once welcomed traders along the ancient Silk Road with rivers, lakes, and lush forests, yet today the region's farmland and grassland are increasingly being engulfed by the sands of the Gobi Desert. The severity of this incremental catastrophe for a declining population of 300,000 residents has brought...

Evaluating the Effects of Alleyway Management on the Performance of Dry-Farmed Pinot noir Grown in Different Soils

Creator:: Lange, Mathew
Abstract:: Vineyards in Oregon’s Willamette Valley are predominately planted to perennial grass cover in the alleyways of vineyards. This grass cover is grown to increase worker and equipment traction, as well as reduce erosion and manage vine vegetative vigor. However, with increasing frequencies of drought and warming temperatures, the use of...

Seed-Lab : a database management system for seed laboratories

Creator:: Maristany, Alberto G.
Abstract:: Seed-Lab, is a software system for managing seed laboratory information. It was developed at the Oregon State University Seed Testing Laboratory. Seed-Lab was built around a database development package Revelation, which provides its own programming language. Seed-Lab shields the user from the complexities of database management by supporting menu driven...

Genomic comparisons of seed-transmissible and non-seed-transmissible strains of cucumber mosaic virus

Creator:: Ried, Jeffrey L.
Abstract:: A sensitive assay for the analysis of contaminating segments in pseudorecombinants constructed from a seed-transmissible (CVM-Pg) and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic virus was developed using partial RNase T₁ digestion. Isolated genomic RNA segments produced unique digestion patterns when 3'- end labeled, treated with RNase T₁, and subjected...

Osmotic stress vigor test for wheat seed

Creator:: Currans, Sean
Abstract:: Seed vigor tests have been developed to evaluate the relative ability of seed lots to produce stands of seedlings in the field. Some workers have suggested the possibility of differentiating vigor levels by germinating seeds under osmotic stress, but have not conducted field trials to evaluate the usefulness of the...

The effect of winter grazing on production and dynamics of a Lolium perenne (L.)-Trifolium repens (L.) pasture

Creator:: Jaindl, Raymond G.
Abstract:: Perennial ryegrass (Lolium perenne) - white clover (Trifolium repens) hill-land pastures were grazed at different times in the winter to study the effect of time of winter grazing on plant response and forage production. The same pastures were grazed by sheep once in early December, January, February, March, or April...
