⁴⁰Ar/³⁹Ar Dating of Umpqua Group Sediments within the Oregon Coast Range: Implications for Provenance

Creator:: Acito, Sydney K.
Abstract:: New detrital mica ages from the Umpqua Group of the Oregon Coast Range provide constraints on models of Eocene sedimentation. Based on sandstone petrography, previous studies assert that the Klamath Mountains to the south are the most likely source region for Umpqua Group sedimentary provenance. However, the presence of Late...

Effect of Fire Severity on Forest Development in a Mature Douglas-fir Forest in Western Oregon

Creator:: Hidzick, Maxim S.
Abstract:: Wildfires can create alternative pathways for forest development, and wildfires have expanded in size, frequency, intensity, and severity across the western United States. The purpose of this paper is to compare forest development of a mature Douglas-fir forest in western Oregon across fire severities. Postburn field measurements were collected in...

Generation of expression plasmids to study the function of the PRC2 subunit Suz12 in Fusarium graminearum

Creator:: Park, Catherine
Abstract:: The Polycomb Repressive Complex 2 (PRC2) catalyzes genome transcription repression through the methylation of lysine residue 27 in the amino terminal region of histone 3 (H3K27me1/2/3) [2], [7]. PRC2 is made up of three highly conserved core subunits: Kmt6, Eed, and Suz12. Accurate distribution of PRC2 is essential for proper...

A preliminary assessment of post-fire dissolved organic carbon concentrations in the McKenzie River basin, Oregon

Creator:: Hyatt, Charles
Abstract:: In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...

The Effects of Wildfire on Soil Hydraulic Properties in an Appalachian Hardwood Forest

Creator:: Ruud, Danica R.
Abstract:: Wildfires can affect soil physical properties, resulting in changes in infiltration, hillslope runoff, groundwater recharge, and sediment and dissolved nutrients to streams. In November 2016, the Chimney Tops 2 Fire burned 4,617 ha of Appalachian hardwood forest in eastern Tennessee. A portion of the fire burned through a National Ecological...

Exotic Species Success in Fire- and Harvest-Disturbed Forest Sites in Southwest Oregon

Creator:: Pearce-Smith, Sarabeth
Abstract:: Invasive plant species are a significant concern in Oregon’s forests, particularly in early-seral sites. Early-seral forests are generated by severe disturbances such as fire or timber harvest, and persist until canopy closure. They are vulnerable to invasion because they have abundant resources, and are important because they provide unique resources....

Wildfire Severity Has a Minimal Influence on Pollen Diversity Used by Developing Mason Bees (Osmia lignaria) in Mixed Conifer Forest

Creator:: Bell, Nicole C. S.
Abstract:: Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...

Dissolved Organic Carbon Production and Flux from Long Term Litter Manipulations in a Pacific Northwest Old-Growth Forest

Creator:: Evans, Lucas R.
Abstract:: Dissolved organic carbon (DOC) flux is an important mechanism to convey soil carbon (C) from aboveground organic debris (litter) to deeper soil horizons and can influence the formation of stable soil organic carbon (SOC) compounds. Aboveground litter quantity and quality was manipulated for 20-years in an old-growth Douglas fir forest...

Examining the effect of annual grass invasion on fire spread and severity: fuel modeling for Ventenata dubia

Creator:: Gibson, Simone
Abstract:: This study examines the relationship between an invasive annual grass, Ventenata dubia, and fire behavior in three non-forested ecotypes within the Ochoco National Forest: stiff sage, low sage, and wet meadows. Fire is an essential ecological function of ecotypes found within the Ochoco landscape. The stiff sage ecotype is a...

Geographic variation in the seed mycobiome of Coastal Douglas-fir (Pseudotsuga menziesii var. menziesii)

Creator:: Bergmann, Gillian E.
Abstract:: Seeds are an essential component of plant life histories, and seed endophytes have the potential to influence germination, seedling establishment and development. That said, seed endophytes are a relatively new area of study, both in the factors that influence which taxa are present and how these microbes alter plant function....
