Effects of oil and natural gas development on territory occupancy of ferruginous hawks and golden eagles in Wyoming, USA

Creator:: Wallace, Zachary P.
Abstract:: Energy development is expanding rapidly across the western US. Negative effects have been documented for some wildlife, but consequences of development are unclear for other taxa, including raptors. We had the opportunity to examine effects of oil and natural gas development on two raptor species of conservation concern, ferruginous hawks...

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...

Lichen Studies of Tropical Dry Forest: A Systematic and Ecological Approach

Creator:: Miranda-González, Ricardo
Abstract:: In recent years, our ecological knowledge of tropical dry forests has increased dramatically. However, whole components of the ecosystem, like lichenized fungi, remain mostly unknown. Crustose lichens in these forests are so abundant, that they are responsible for the characteristic appearance of a “white bark forest” during the dry season....

Canyon Grasslands of the Hells Canyon National Recreation Area : How have they changed over time and what is their future trajectory?

Creator:: Pack, Samantha J.
Abstract:: The canyon grasslands of the Hells Canyon National Recreation Area (HCNRA) are a unique ecosystem within the Pacific Northwest Bunchgrass Region (PNWBR) with a long history of natural and anthropogenic disturbances including fire, invasive species introduction, historical livestock grazing, and cultivation. Even with this history, these canyon grasslands contain some...

Eugene Residents Risk Perceptions of Water Scarcity

Creator:: Leitermann, Lily
Abstract:: Potential water scarcity and drought conditions are predicted in and around Eugene, Oregon due to decreased snowpack and subsequent decreased snowmelt in the Western Cascade Mountains. This phenomenon was triggered by a long-term trend of warmer winters scientifically linked to global climate change patterns (Dalton et al. 2013). Numerous stakeholders,...

Towards the Design and Evaluation of Effective Educational Virtual Reality Applications

Creator:: Rangarajan, Vaishnavi
Abstract:: With the rapid advancement of educational technology and the need for personalized, engaging content to accommodate diverse learning needs, Virtual Reality (VR) holds promises for the present and future. However, VR applications suffer from challenges, including usability concerns, lack of pedagogical value, and evaluation standards. This thesis focuses on two...

Ontogenetic Shifts in Disease Response in Native and Invasive Anuran Species

Creator:: Urbina Gonzalez, Jenny Cecilia
Abstract:: This dissertation presents a different approach to understanding how amphibians are responding to disease through ontogeny. Although numerous efforts have been conducted to understand host responses to the fungus Batrachochytrium dendrobatidis (Bd), studies have been restricted to distinct developmental stages. This dissertation provides information on host response to Bd across...

Determining the Impacts of Dormant Pruning Methods and Nitrogen Fertilization on Vitis vinifera 'Pinot noir' Bud Fruitfulness and Yield

Creator:: Ulmer, Miranda R.
Abstract:: The majority of grapes grown in Oregon are produced in Western Oregon’s Willamette Valley, where two-thirds of the acreage is planted to Pinot noir. The production of Pinot noir in the Willamette Valley comes at a high cost, and growers are seeking ways to increase profits while maintaining quality fruit...

Evaluating the Effects of Alleyway Management on the Performance of Dry-Farmed Pinot noir Grown in Different Soils

Creator:: Lange, Mathew
Abstract:: Vineyards in Oregon’s Willamette Valley are predominately planted to perennial grass cover in the alleyways of vineyards. This grass cover is grown to increase worker and equipment traction, as well as reduce erosion and manage vine vegetative vigor. However, with increasing frequencies of drought and warming temperatures, the use of...

Production and partitioning of organic matter during simulated phytoplankton blooms

Creator:: Wetz, Michael S.
Abstract:: Few studies have examined the partitioning of organic matter in upwelling systems, despite the fact that these systems play a key role in carbon and nitrogen budgets in the ocean. We examined the production and partitioning of phytoplankton-derived organic matter in deck incubations off Oregon during the upwelling season. During...
