Targeted enrichment strategies for next-generation plant biology

Creator:: Cronn, Richard, Knaus, Brian J., Liston, Aaron, Maughan, Peter J., Parks, Matthew, Syring, John V., and Udall, Joshua
Abstract:: • Premise of the study: The dramatic advances offered by modern DNA sequencers continue to redefine the limits of what can be accomplished in comparative plant biology. Even with recent achievements, however, plant genomes present obstacles that can make it difficult to execute large-scale population and phylogenetic studies on next-generation...

Host plant dependent disease progression of the microsporidian parasite Nosema tyriae on Cinnabar moth larvae

Creator:: Berns, Kathryn, Buergi, Linda, and McEvoy, Peter
Abstract:: Tyria jacobaeae was introduced as a biological control agent to control the noxious weed Jacobea vulgaris. Eventually introduced to the Cascade mountain range of Oregon, T. jacobaeae has been found to feed on Senecio triangularis, a native plant closely related to J. vulgaris. Nosema tyriae is a parasitic fungus under...

Non-target Effects of Biological Control: Ecological Risk of Tyria jacobaeae (Lepidoptera: Erebidae) to Senecio triangularis (Asteraceae) in Western Oregon

Creator:: Rodman, Madison G.
Abstract:: Non-target effects are one of the greatest potential risks of weed biological control programs, and understanding non-target effects of biological control at the population level is crucial for predicting when they will occur and altering the perception of biological control as a whole. In this thesis, we assessed the ecological...

Escape in Time: Phenology Mitigates Impacts of the Introduced Cinnabar Moth, Tyria jacobaeae, on Native Herb Senecio triangularis in Western Oregon

Creator:: Lunde, A. Katarina
Abstract:: Classic biological control can be a powerful option for those tasked with managing biological invasions; however, some biocontrol releases lead to non-target attack – feeding, damage or development on species other than the target species. The cinnabar moth, Tyria jacobaeae L. (Lepidoptera: Erebidae) was introduced to Western Oregon as a...

Influence of site, soil, and inoculum density on dwarf bunt (Tilletia controversa Kühn) of winter wheat

Creator:: Clark, Deborah Ann, 1954-
Abstract:: Field microplot studies conducted over two seasons (1982-1984) evaluated the influence of four physically and chemically diverse soils collected from Pacific Northwest wheat fields on the incidence of dwarf bunt of winter wheat caused by Tilletia controversa Kuhn. These soils were placed at Flora and Pendleton, Oregon to determine the...

Serpentine and non-serpentine edaphic ecology and the recovery of Lomatium cookii (Apiaceae), an endangered endemic of southwest Oregon

Creator:: Silvernail, Ian S.
Abstract:: The role of unusual geologies in plant distribution and form is well-known. Serpentine (ultramafic) soils exert a particularly strong influence on plants, as evidenced by a high level of endemism and the morphological and physiological traits displayed in adaptation to the extraordinary chemistry of these substrates. Adaptation may lead to...

Decadal Changes in Lichen and Vegetation Communities in Relation to Metal Deposition and Climate in Northern Alaska

Creator:: Di Meglio, Elisa B.
Abstract:: The Red Dog Mine transports concentrated zinc and lead ore in northwestern Alaska through Cape Krusenstern National monument along a haul road. High metal levels in the moss Hylocomium splendens along the haul road have been attributed to ore dust released during transport. The mine has implemented several pollution abatement...

Lichen communities and caribou habitat in Denali National Park and Preserve, Alaska, USA

Creator:: Nelson, Peter R.
Abstract:: Lichens play many important roles in subarctic terrestrial ecosystems by fixing nitrogen, colonizing rock and gravel, stabilizing otherwise bare soil, adding significantly to vegetation biodiversity and serving as the primary food for caribou in the winter. In these chapters, I analyzed lichen community and ecological trait structure along environmental gradients,...

Environmental factors influencing the rate of spread of Phellinus weirii (Murr.) Gilbertson in young-growth Douglas-fir

Creator:: Angwin, Peter A.
Abstract:: Studies to identify the environmental factors that influence the rate of ectotrophic mycelial growth of Phellinus weirii (Murr.) Gilbertson along Douglas-fir roots were undertaken both in the laboratory and in the field. The effects of soil pH, nitrogen, moisture, temperature, microorganisms and bulk density were investigated. In the lab, the...
