Diet overlap by DNA metabarcoding of mule deer, elk, and cattle in ponderosa pine forest of eastern Oregon

Creator:: Faber, M. Kate
Abstract:: Millions of acres of rangeland in the western U.S. is shared habitat by elk (Cervus canadensis), mule deer (Odocoileus hemionus), and cattle (Bos taurus). Potential competition between these ungulates for the same forage species can be understood from their diet composition. I used DNA metabarcoding methods with trnL primers to...

That’s Not in My Position Description: A Discourse Analysis Study of SBAE Teacher Migratory Context

Creator:: Haddad, Becky
Abstract:: The purpose of this study was to unfold positions of migrating SBAE teachers to understand support and challenge to retain teachers in migratory contexts. Previous literature discusses problems related to teacher mobility as functions of teacher-student matching, teacher skill and effort, school environments, and advancing student learning. In an effort...

The grassroots response to HIV/AIDS in Nyanza Province, Kenya : an analysis of the community-based approach for combating the multisectoral impact of an epidemic

Creator:: Johnson, Becky A.
Abstract:: From July to September, 2002 I spent ten weeks in Kenya conducting full-time research on the macroeconomic impact of HIV/AIDS and community action towards combating the epidemic in locations dominated by members of the Luo tribe in Nyanza Province, Kenya. Gathering data from both the Ministry of Health and non-governmental...

Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

Aboveground vegetation and viable seed bank of a dry mixed-conifer forest at a wildland-urban interface in Washington state

Creator:: Snider, Gabrielle
Abstract:: Dry coniferous forests in the western United States are experiencing severe wildfires, insect outbreaks, forest disease epidemics and a growing presence of invasive species. Policies strongly emphasize reducing hazardous fuels at the Wildland Urban Interface (WUI) where communities and forests intersect. However, these areas present restoration challenges as they tend...

Characterizing an Annual Grass Invasion and Its Link to Environmental and Disturbance Factors Using Remote Sensing: New Tools and Applications

Creator:: Nietupski, Ty C.
Abstract:: The spread of nonnative species across the globe has contributed to biodiversity loss and changes in ecosystem structure and function. Monitoring the introduction, naturalization, and spread of introduced species is critical in abating negative impacts wrought by species invasions. However, providing basic information concerning the presence or spread of many...

Pacific Madrone Leaf Blight Detection with Unmanned Aerial Systems and Machine Learning

Creator:: Barker, Matthew I.
Abstract:: Ground-based assessments of foliar diseases including leaf blight are time-consuming and costly. We investigated the potential for using an unmanned aerial system (UAS) in conjunction with a multispectral sensor to determine whether we could more efficiently and reliably detect and quantify leaf blight in Pacific madrones. Our methods included ground-based...

Oxidative stress and muscle dysfunction following anterior cruciate ligament surgery

Creator:: Barker, Tyler
Abstract:: Despite the advances in surgery, physical therapy, and pharmaceutical agents, muscle dysfunction (i.e., atrophy and weakness) continues to impair recovery from an anterior cruciate ligament (ACL) injury and surgery. Ischemia-reperfusion injury during surgery and the subsequent limb disuse are two events experienced by patients having ACL surgery. Oxidative stress and...

Effects of silver ions and nanoparticles on suspended cells and biofilms of Nitrosomonas europaea

Creator:: Barker, Leila Kelly
Abstract:: Silver nanoparticles are increasingly being incorporated into consumer products due to their broad-spectrum antimicrobial properties. The resulting influx of silver nanoparticles into wastewater may pose a threat to bacteria involved in biological wastewater treatment. Ammonia-oxidizing bacteria, which convert ammonia to nitrite in the first step of nitrification, are highly sensitive...

Nutrient limitation of dune grasses in a U.S. Pacific Northwest coastal dune system

Creator:: Barker, McKenzie J.
Abstract:: Coastal dunes provide many functions and services including coastal protection, recreation, and habitat. Vegetation contributes to dune growth and stability, thereby increasing the coastal protection value of dunes. On the U.S. Pacific Northwest coast, the dominant dune grasses are the introduced non-native American beachgrass (Ammophila breviligulata) and the native American...
