Mycological Maintenance of Rangelands and the Impacts of a Thatch Forming Invasive Annual Grass (Taeniatherum caput-medusae)

Creator:: Hovland, Matthew
Abstract:: Arbuscular mycorrhizal fungi (AMF) may exert profound influences on ecosystem resilience and invasion resistance in western North American sagebrush steppe and other arid rangeland plant communities. Maintenance of plant community structure through ecological feedbacks such as facilitation of nutrient cycling and uptake by host plants, physical and chemical contributions to...

Long-term Fire Effects on Plant Succession and Exotic Weeds in Protected Area Sagebrush Steppe, John Day Fossil Beds National Monument, Oregon

Creator:: Reed-Dustin, Claire Marie
Abstract:: The historical function of fire in sagebrush steppe has been altered by 19th century overgrazing, active fire suppression, annual grass invasion and encroachment of woody species. The significance of fire to these systems is known, but research on long-term fire effects are limited. The Sheep Rock management unit of the...

Response of Striga-susceptible and Striga-resistant sorghum genotypes to soil phosphorus and colonization by an arbuscular mycorrhizal fungus

Creator:: Leytem, Alicia B.
Abstract:: Striga, a genus of obligate parasitic weeds in the family Orobanchaceae, has been identified as the most important biological factor limiting agricultural productivity in sub-Saharan Africa. Germination of Striga seeds is triggered by strigolactone root exudates from host plants. Strigolactones also induce hyphal branching in arbuscular mycorrhizal (AM) fungi, which...

Rosa Gonzalez Gomez : a Mexican woman's story

Creator:: Browning, Richard L.
Abstract:: Using an oral history method, the author has recorded the life history of Rosa González Gómez, a Mexican woman who spends part of each year in the United States and part in Mexico. Comparing the story of Rosa's life, as told in her own words, with literature in the social...

Aspen Drought Stress Response, Snow Cover and Soil Moisture Dynamics on an Oregon Bunchgrass Prairie

Creator:: Neary, Andrew
Abstract:: Quaking aspen, Populus tremuloides, has experienced severe declines in recent years in part due to the effects of changing climate and extreme drought. As the dominant deciduous tree in Western North American forests, aspen plays a critical role in forest biodiversity and ecosystem function. Therefore, the persistence of this species...

The Mountain Pine Beetle, Climate Change and Sustainable Forestry in the Northern Rocky Mountain

Creator:: Gillen, Amanda
Abstract:: Mountain pine beetles (MPB) have killed millions of acres of forest throughout the Rocky Mountain ecoregion in the United States and Canada and climate change may be intensifying outbreaks. Climate change can change forest ecosystems and dynamics by increasing drought conditions and intensifying heat waves. Due to changing climate conditions,...

Low-Income Adolescents’ Physical Activity Levels in Rural Coastal Community: A Gender and Ethnic Comparison.

Creator:: Massa-Gonzalez, Ada N.
Abstract:: Physical Activity (PA) has been shown to significantly improve the overall health of adolescents. The health dimensions that are positively influenced by a consistent level of PA are multiple and range from body composition, chronic diseases management (diabetes, cardiovascular disease, etc.), chronic pain, and mental health (depression, anxiety, etc.). The...

Analytical method development for the identification, detection, and quantification of emerging environmental contaminants in complex matrices

Creator:: Place, Benjamin J.
Abstract:: The development of analytical methods for emerging contaminants creates many unique challenges for analytical chemists. By their nature, emerging contaminants have inherent data gaps related to their environmental occurrence, fate, and impact. This dissertation is a compilation of three studies related to method development for the structural identification of emerging...

Addressing wastewater epidemiology limitations with the use of dynamic population surrogates, complementary urinalyses and in-situ experiments

Creator:: Brewer, Alex J.
Abstract:: Wastewater epidemiology is an emerging discipline that requires collaborative research involving analytical chemists, drug epidemiologists, and wastewater engineers. Wastewater epidemiology involves the sampling and quantitative analysis of raw wastewaters from communities for illicit drugs and their metabolites. Mass loads (mass per day) and per capita (mg per day per person)...

Large volume (1,800 µL) injection HPLC/MS/MS for the quantitative determination of illicit drugs and human urinary biomarkers in municipal wastewater

Creator:: Chiaia Hernandez, Aurea C.
Abstract:: A sensitive, selective, rapid analytical method based on large-volume injection (LVI) liquid chromatography/ tandem mass spectrometry was developed using commercially-available hardware that eliminates the need for either off-line or on-line solid phase extraction. Centrifugation followed by the direct injection of 1,800 µL was used for the quantification of illicit drugs,...
