New Tools for Managing Erysiphe necator: Rapid Sampling Approaches and an Exploration of Grower Opinions and Perspectives towards Collective Action and Information Transfer

Creator:: Lowder, Sarah R.
Abstract:: The scale of pest and disease dispersal is often larger than the scale of individual farms. Therefore, an individual grower’s response to pests and diseases can affect and is affected by their surrounding growing region. Individual growers are also not isolated, and engage in various forms of information gathering, sharing,...

Inferring Patterns and Processes of Emergence in Clonal Phytophthora Epidemics using Population Genomic Approaches

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

An Interdisciplinary-Botanical Perspective for Cultural Resource Management: A Definition and the Application of Culturally Significant Plants in Identification, Interpretation, and Evaluation for the National Register of Historic Places

Creator:: Burk, Rene F.
Abstract:: Cultivated plants are often living artifacts that can aid in evaluation of historic or cultural landscapes. However, a working definition for “culturally significant plant” is currently lacking in the guidance literature for the cultural resource management practitioners. Based on a review of the literature on cultivated plants as indicators of...

Litter decay processes and soil nitrogen availability in native and cheatgrass-dominated arid rangelands

Creator:: Harrison, Kristen S.
Abstract:: As large-scale restorations of degraded rangelands are initiated, land managers need to understand how decades of dominance by the invasive annual grass, cheatgrass (Bromus tectorum L.), have altered ecosystem processes. One way to assess such alterations is by observing differences in decay rates, since decomposition is determined by factors such...

Silviculture Impacts and Population Genomics of Coniferiporia sulphurascens, the Causal Agent of Laminated Root Rot

Creator:: McMurtrey, Shawn
Abstract:: Within the Pacific Northwest, USA, root diseases of conifers are a major forest health concern. These diseases are primarily caused by basidiomycete fungi. These fungal associates play a vital role in carbon sequestration but also have a significant negative economic impact within the timber industry. As a result, research on...

Insights into Novel Non-Fumigant Nematicides: Physiological and Cellular Responses of Meloidogyne Incognita and Other Plant-Parasitic Nematodes

Creator:: Wram, Catherine L.
Abstract:: Plant-parasitic nematodes (PPN) pose a severe threat to crop production with the economic losses due to nematode parasitism in excessive of US$ 80 billion each year. Meloidogyne incognita, a globally distributed pest with a diverse host range, contributes significantly to this economic loss. The most reliable way to manage PPN...

Conservation of Rorippa columbiae : an evaluation of reintroduction potential through the study of germination ecology, propagation methods, and habitat requirements

Creator:: Kentnesse, Laura E.
Abstract:: Rare plant reintroductions are a critical conservation tool for the augmentation of diminishing populations, or re-establishment of extirpated populations. Analysis of reintroduction failures suggests that a sophisticated understanding of species biology, ecology, and habitat is essential for producing self-sustaining rare plant populations. This study sought to generate that background knowledge...

Relationships of exotic species and wildfire to the threatened plant Silene spaldingii

Creator:: Menke, Carolyn A.
Abstract:: In the canyon grasslands of Garden Creek Ranch Preserve in Idaho, where the threatened plant Silene spaldingii occurs and invasion by the exotic species Centaurea solstitialis and Bromus tectorum is proceeding rapidly, I examined environmental and community patterns of site invasion, and evaluated the apparent influence of invasion on Silene...

The association of epiphytic macrolichens and bryophytes with riparian stand types along a valley continuum, Oregon Coast Range

Creator:: Ruchty, Andrea M.
Abstract:: I surveyed epiphytic macrolichens and bryophytes in six stands in each of seven riparian stand types in the Oregon Coast Range. This study (Chapter 2) describes the association of epiphytes with stand types and the corresponding potential of forest canopy conversions to affect epiphyte communities. Species composition, diversity, and representation...

Landscape Genomics and Climatic Responses of Willamette Valley Alders

Creator:: Kral, George L.
Abstract:: The climate of the Pacific Northwest is in flux, and existing forest ecosystems are stressed and poised to shift in fundamental ways, with or without human intervention. This dissertation probes the nature of forest responses to environmental change through investigations of morphology and genetics of three species of alder co-occurring...
