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...

Investigation of Glacier Dynamics During the Last Glacial Maximum at Tioga Pass, Yosemite National Park

Creator:: Laub, Alexander G.
Abstract:: Previous investigations of glacier dynamics at Tioga Pass during the Last Glacial Maximum (LGM) have produced different conclusions. A map of the LGM ice extent and flow direction (Alpha et al., 1987) illustrates a south-to-north direction of ice flow across the pass with little evidence to support this inference. Since...

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...

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...

Hi-C genome assembly of the ectomycorrhizal fungus Rhizopogon salebrosus

Creator:: Har, Skyler
Abstract:: Rhizopogon salebrosus is an abundant ectomycorrhizal fungus common throughout Western North America that forms mutualistic partnerships with Pinus species. Studied for its systematics, use in sapling nurseries, post-fire seedling establishment, and unique evolutionary history, R. salebrosus holds many secrets within its genome. This thesis aims to characterize the mating system,...

The geometry of the octonionic multiplication table

Creator:: Killgore, Peter Lloyd
Abstract:: We analyze some symmetries of the octonionic multiplication table, expressed in terms of the Fano plane. In particular, we count how many ways the Fano plane can be labeled as the octonionic multiplication table, all corresponding to a specified octonion algebra. We show that only 28 of these labelings of...
