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-destructive methods to determine microsporidian infection levels in cinnabar moth larva

Creator:: Woolsey, Kelsey, Büergi, Linda, and McEvoy, Peter
Abstract:: The Cinnabar moth, Tyria jacobaeae, has been introduced to North America in an effort to control the invasive plant Jacobaea vulgaris. The Cinnabar moth is the main host of Nosema tyriae. When infection levels are high, N. tyriae can shorten the lifespan and affect reproduction of the Cinnabar moths. The...

Quantifying dissipative beach and vegetated dune morphology with multiple aerial photography systems

Creator:: Conlin, Matthew P.
Abstract:: Sand dunes provide coastal communities critical protection from flooding and erosion, as well as a habitat for a range of species- some threatened or endangered. As such, it is of importance to develop a quantitative understanding of the processes through which these systems evolve at a variety of temporal and...

Optical Tweezer Trapping of Colloidal Polystyrene and Silica Microspheres

Creator:: Peters, Kyle C.
Abstract:: Optical trapping is a tool used throughout a wide variety of disciplines rang- ing from precisely probing and manipulating sub-micron organisms in biol- ogy to analyzing fundamental charge transfer in colloidal physics. This thesis presents research involving optical tweezer force measurements of polystyrene and silica microspheres. In addition, preliminary work...

In search of ecological advantages : Mycorrhizal facilitation of big huckleberry Vaccinium membranaceum (Doug.)

Creator:: Stocking, Peter
Abstract:: Temperate evergreen forests of the Pacific Northwest support big huckleberries (Vaccinium membranaceum) despite their nutrient impoverished soils. Acquisition of nitrogen and phosphorous are the major nutrients limiting V. membranaceum. The plant’s access to these resources is linked to their mycorrhizal symbiosis. To learn more about the symbionts of eriaceous plants...

Soil Fire Ecology: Assessing Wildfire Severity Impacts on Pacific Northwest Forest Soil Carbon

Creator:: Fleetwood, Shea
Abstract:: Pacific Northwest temperate rainforests are anticipated to experience increasingly frequent and severe wildfires in the foreseeable future due to climate change, increased fuel loads, and deforestation. Soil, underlying these forests, is the largest terrestrial carbon (“C”) reservoir. Fire disturbance influences soil C persistence, the timeframe and magnitude of which remain...

Development of a Antibacterial Disc Diffusion Assay to Differentiate Fusarin C from Non-Fusarin C activity in Early Screening of Mutant Fusarium graminearum Extracts

Creator:: Svendsen, Molly, Luelling, Sarah, Adpressa, D., Godbey, Aly, Belizi, Peter, Carlson, Caleb, Loesgen, S., Freitag, M., Smith, Kristina, and Gautschi, Jeff
Abstract:: The discovery of novel compounds with antibacterial properties continues to be critically important.3 One potential source of such compounds is the cryptic genome of fungi known to produce biologically active molecules. A kmt6 mutant of the cereal pathogen Fusarium graminearum was previously developed through a histone H3 lysine 27 methyltransferase...
