Systematic, genomic, and transcriptomic analysis of mycoparasitic Tolypocladium species and their Elaphomyces hosts

Creator:: Quandt, C. Alisha
Abstract:: Fungi in the genus Tolypocladium are diverse in their host associations, but the predominant ecologies include parasites of the ectomycorrhizal genus Elaphomyces and pathogens of insects. The aim of this dissertation research is to examine the evolution of these fungi and their host associations. To accomplish this several lines of...

Investigating Vibrio parahaemolyticus interactions with the Pacific oyster, Crassostrea gigas

Creator:: Aagesen, Alisha M.
Abstract:: Vibrio parahaemolyticus is a Gram-negative, halophilic, human pathogenic bacterium ubiquitous in the marine environment. Like many Vibrio species, V. parahaemolyticus commonly associates with shellfish, particularly oysters. Ingestion of a raw or under cooked oysters contaminated with V. parahaemolyticus can cause gastroenteritis, which is typically self-limiting and rarely causes death. Globally,...

Modeling animal movement to manage landscapes

Creator:: Larson-Praplan, Stephanie
Abstract:: Managing rangelands with livestock grazing is a tool that can be applied to obtain vegetation management objectives. Animals utilize available resources, which vary in quantity and quality, across the landscape. Their movements are adjusted to the spatial and temporal heterogeneity of resource distribution. Controlling livestock distribution is fundamental to economically...

Responses of vegetation and sheep to three grazing pressures

Creator:: Thetford, Frank Oren
Abstract:: A study was conducted over a two year period, 1973 through 1974, on perennial ryegrass-subclover pastures with stocking rates of 7.4 (moderate), 9. 9 (heavy), and 12.4 (overstocked) ewes per hectare to establish guidelines on stocking intensity for dryland improved pastures in western Oregon. Climatic conditions varied annually and caused...

An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...

An intrinsic codimension two cellular decomposition of the Hilbert cube

Creator:: Ghimire, Kailash C.
Abstract:: Cellular sets in the Hilbert cube are the intersection of nested sequences of normal cubes. One way of getting cellular maps on the Hilbert cube is by decomposing the Hilbert cube into cellular sets and using a quotient map. By using a cellular decomposition of the Hilbert cube, an example...

Development and Application of Tools for Genetic Analysis of Clonal Populations

Creator:: Kamvar, Zhian N.
Abstract:: Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...

Drug Discovery and Chemical Ecology Investigations of Specialized Metabolism in Tolypocladium and Paraisaria

Creator:: Tehan, Richard M.
Abstract:: Since the discovery of penicillin in 1928, the fungal kingdom has remained a fertile source for the discovery of new, biologically active, natural products. Further, as natural products continue to be discovered from fungi, a deeper understanding of the critical role of specialized metabolism in fungal ecology is afforded. The...

Candidate Genes Associated with Blister Rust Resistance in Whitebark Pine (Pinus albicaulis) Revealed through de novo Transcriptome Assembly and Differential Gene Expression Analysis

Creator:: Bair, Zolton J.
Abstract:: Whitebark pine (Pinus albicaulis) is an iconic North American high-elevation tree species currently threatened by climate change, mountain pine beetle, and white pine blister rust (WPBR), a lethal disease caused by the non-native fungal pathogen Cronartium ribicola. In collaboration with the USDA Forest Service Dorena Genetic Resource Center, germplasm was...

Secondary Metabolism in Tolypocladium : Characterization, Ecology, Evolution and Regulation

Creator:: Blount, Rheannon Rua
Abstract:: An increased understanding of secondary metabolism in fungi is important for both biological and societal reasons. The ascomycete genus, Tolypocladium, is an ideal system to explore secondary metabolism characterization, ecology, evolution and regulation. The genus produces and has the genomic potential to produce a wide array of metabolites. Paired with...
