Contribution of native plasmids to fitness of Pantoea vagans C9-1, a biological control agent for fire blight of apple and pear

Creator:: Klein, Jeannie M.
Abstract:: Pantoea vagans C9-1 (C9-1) is a biological control agent sprayed onto apple and pear trees during bloom for suppression of fire blight, a devastating bacterial disease caused by Erwinia amylovora. Prior bioinformatics studies of C9-1 focused on predicted phenotypes associated with the three native megaplasmids, pPag1, pPag2, and pPag3, and...

Factors influencing population density of stream-living Redband Trout in southeast Oregon, USA

Creator:: Thorson, Justin M.
Abstract:: Fisheries managers often use models of population density to evaluate the status of stream-living fishes, but many of these models have low predictive performance for abundance and density. These models could incorporate several factors that can limit population density, particularly the effect of body size, envisioned by the theory of...

An Ecoregion-Based Reference Condition and Classification Scheme for Determining Nutrient Criteria in Oregon Lakes

Creator:: Brenner, Jacqueline M.
Abstract:: The anthropogenic introduction of nutrients to water bodies has been shown to alter the structure and function of natural aquatic ecosystems, yet national EPA lake and reservoir nutrient criteria remain too broad for effective regional water quality management. This study uses a reference site approach to propose numeric nutrient criteria...

The effects of burning in mountain big sagebrush on key sage grouse habitat characteristics in southeastern Oregon

Creator:: McDowell, Michelle K. D.
Abstract:: Sage grouse are a species of concern because their abundance, distribution, and productivity have declined during the past century. Sage grouse productivity has been linked to specific habitat components including particular forbs and native bunchgrasses. Studies on the effects of fire were conducted in Southeastern Oregon in mountain big sagebrush...

Evaluating balance and strength of older women in exercise programs

Creator:: Dinger, Melanie
Abstract:: Falls are a common problem among older adults, including those who are relatively healthy and living independently. Exercise has been recommended as an intervention to reduce falls by slowing and/or reversing age-related declines in balance, strength, and mobility. However, it remains unclear which types or combinations of programs are most...

Differences in University Students' Self-Determined Motivation, Perceived Competence, and Physical Activity Behavior at Institutions with Either a Required or an Elective Physical Activity Education Policy

Creator:: Kim, MooSong
Abstract:: The overarching premise of this dissertation is to understand how different college and university physical activity education policies affect college and university students. Fundamentally, some American colleges and universities require their students to complete a physical activity education requirement whereas others do not. Given the different policy arrangements of college...

Influences of Thermal and Trophic Heterogeneity on Phenology, Growth, and Resource Use by Juvenile Coho Salmon

Creator:: Campbell, Emily Y.
Abstract:: Ecological resources available to freshwater fish shift spatially, temporally and across life stages. To better understand how spatial-temporal availability of resources influence fish, I examined the phenologies of hatching and emergence of Coho Salmon (Oncorhynchus kisutch) in streams with contrasting and strongly defined seasonal thermal variability. The study streams included...

An evaluation of species-area curves created from a systematically sampled date set using an automated accumulation technique

Creator:: Dale, Becci
Abstract:: This paper examines the influence of species, method, and area on automated species-area curve created from a systematically sampled data set. Because this is a new approach to species-area curves, three tests were run to evaluate the performance of the data sets and accumulation technique. The tests involved 1) range...

Evaluating the Ecological Trade-Offs of Riparian Thinning for Stream Ecosystems in Second-Growth Redwood Forests of Northern California

Creator:: Roon, David A.
Abstract:: Riparian forests provide a myriad of ecosystem functions for adjacent streams and rivers, and due to these linkages, changes in riparian forest conditions can have direct implications for stream ecosystems. Resource managers in the coast redwood forests (Sequoia sempervirens) of northern California (USA) are actively thinning second-growth stands to accelerate...

Inducing and Evaluating Phenotypic and Cytometric Variation in Landscape Plants : Observations from Acer, Ornithogalum, and Penstemon

Creator:: Lattier, Kim Shearer
Abstract:: Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....
