Spring Nitrogen, Plant Growth Regulator, and Defoliation Effects on Seed Production in Two Fine Fescue (Festuca rubra L.) Species

Creator:: Anderson, Nicole P.
Abstract:: One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...

Petrogenesis of the Steens Basalt : Variation in Source Contributions and Effects of Crustal Passage During the Onset of Columbia River Flood Basalt Volcanism

Creator:: Moore, Nicole E.
Abstract:: Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...

Ecophylogenetic Characterization of the Gut Microbiome of At-risk Companion and Food Animals

Creator:: Kirchoff, Nicole S.
Abstract:: Agricultural and companion animals are integral to our way of life as they provide us with nourishment, financial resources, transportation, and companionship. However, pets, managed animals in the agricultural industry, as well as wild populations of food animals are all subject to health and mortality risks. The gut microbiome is...

Seed Development in Orchardgrass (Dactylis glomerata L.) in Relation to Plant Growth Regulators and Spring Nitrogen

Creator:: Morad, Mohammed M.
Abstract:: Orchardgrass (Dactylis glomerata L.) is an important seed crop, but unlike other cool-season perennial grass seed crops such as perennial ryegrass (Lolium perenne L.) and tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.], seed yields have not increased over time so there is considerable room for improvement. Research suggests that plant growth...

Soil community dynamics in sagebrush and cheatgrass-invaded ecosystems of the northern Great Basin

Creator:: DeCrappeo, Nicole M.
Abstract:: Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...

Single-molecule in vitro Characterization of Otoferlin

Creator:: Hams, Nicole J.
Abstract:: Congenital hearing loss is a common disorder and over 60 mutations in the sensory hair cell protein, otoferlin, have been linked to pre-lingual deafness. Although otoferlin is essential for hearing, the large size and low solubility of the protein have limited approaches to study its function on a molecular-level. To...

Exploration of the use of classroom based physical activity breaks among teachers of students with disabilities

Creator:: Fiscella, Nicole
Abstract:: In 2022, the Report Card on Physical Activity for Children and Youth noted only 24% of children ages 6 to 17 years achieved the recommended 60 minutes of physical activity daily, with a drop in physical activity as children age (Barriss, 2022). More importantly, children with disabilities have been found...

Photostability of organic semiconductors : from bulk to nanoscales

Creator:: Quist, Nicole Arianne
Abstract:: Organic semiconductors have attracted considerable attention due to their applications in low-cost, solution-processable (opto)electronic devices. An important class of high-performance organic semiconductors is pentacene derivatives, which exhibit high charger carrier mobilities in field-effect transistors and ultrafast singlet fission in photovoltaic devices. These derivatives have served as benchmark materials for systematic...

Influence of vegetation on streambank hydraulics

Creator:: Czarnomski, Nicole M.
Abstract:: Proper use of vegetation in streambank bioengineering practices requires a comprehensive understanding of the influence of vegetation density on streambank hydraulics. A series of studies were conducted to investigate the relationship between independent variables vegetation density, bank angle, and discharge and dependent variables channel velocity, resistance, turbulence, and shear stress....

Ecohydrologic Connections of Rangeland Ecosystems in Central and Eastern Oregon, USA

Creator:: Durfee, Nicole M.
Abstract:: In light of water scarcity and the impacts of climate change, there is an increased need to understand the interaction between land use characteristics and ecohydrologic processes in semiarid regions. Additionally, many semiarid and arid regions face various land management challenges, including woody plant encroachment, decreased snowpack, and increased stream...
