Carnivore Competition: Spatial and Dietary Implications of Gray Wolf Recolonization for Cougars in Northeast Oregon

Creator:: Orning, Elizabeth Kari
Abstract:: After a 40-year absence from Oregon’s landscape, expanding gray wolf (Canis lupus) populations are reestablishing elements of interspecific competition with sympatric large carnivores, like cougars (Puma concolor). This presents new challenges for management of large carnivores and their ungulate prey populations (e.g., elk, Cervus canadensis nelsoni; mule deer, Odocoileus hemionus)...

Modeling Fine-scale Avian Distributions and Densities with Multi-scale Models: Predicting the Past and Present

Creator:: Hallman, Tyler A.
Abstract:: Models of a species’ distribution and models of a species’ spatially explicit density are valuable tools for conservation. They allow researchers to estimate changes in distributions, densities, and populations, based on changing environmental conditions. To trust such estimates, however, the quality of models is exceedingly important. Model performance can be...

3D vs. conventional volcanic hazard maps : a user study at Mount Hood

Creator:: Preppernau, Charles A.
Abstract:: Volcanic hazard maps inform the public on the nature and extent of the hazards that threaten them, but these maps are often challenging for those who are not trained in map use or geology. The maps in this study focus on lahars, a dangerous, fast, and far-reaching volcanic hazard that...

Community gradients of Arctic macrolichens in relation to succession, grazing and the environment

Creator:: Holt, Emily A.
Abstract:: The purpose of this dissertation was to define macrolichen community gradients in relation to succession, grazing and the environment. First, species scores indicating when macrolichen species appeared following disturbance were derived from the literature. Weighted averaging of these data with a community matrix created a successional score for each sample...

Cooperation and Conflict Dynamics in Small-Scale Fisheries

Creator:: Villegas, Ciera A.
Abstract:: Small-scale fisheries account for at least 40 percent of global fisheries catch, 90 percent of the people employed along capture fisheries value chains operate in small-scale fisheries, and 45 million women participate in small-scale fisheries globally. The past few years have brought warnings from policymakers and resource managers about risks...

Using GIS to illustrate the geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in Oregon

Creator:: Cohn, Leanne A.
Abstract:: There could be a geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in the United States. Marine renewable energy generation efforts are currently being planned, studied, and initially implemented in the country as a response to climate change. The Bureau of Ocean Energy Management is...

Predicting the stability, equilibrium response, and nonequilibrium dynamics of ecological systems

Creator:: Hosack, Geoffrey R.
Abstract:: In this dissertation, new theory and its applications are developed to predict three properties of complex ecological communities: stability, equilibrium response, and non-equilibrium dynamics. First, a graph-theoretic analysis identifies the interconnections in a complex ecosystem that promote or diminish stability (Chapter 2). The hierarchy of interactions that influences stability and...

Developing a plan for the national coordination of geospatial technology education : a community college perspective

Creator:: Sullivan, Deidre E.
Abstract:: Geospatial technology is a rapidly growing and changing field. The term geospatial technology (GST) refers to geographical information systems (GIS), global positioning systems (GPS), and remote sensing (RS), all emerging technologies that assist the user in the collection, analysis, and interpretation of spatial data. The speed at which new fields...

Fabrication of a flexible glucose sensing catheter for human implantation

Creator:: Matthews, David J.
Abstract:: Flexible electronics processing techniques were applied to integrate a glucose sensor with a hormone-delivery catheter in order to create a cheap and minimally invasive method for patients with type 1 diabetes to continually monitor and control their blood sugar levels. Ultimately, this work intends to move toward the development of...

A macroscale measurement and modeling approach to improve understanding of the hydrology of steep, forested hillslopes

Creator:: Graham, Christopher Brian
Abstract:: The dominant controls on flow generation in steep, forested hillslopes are poorly understood. This dissertation examined the dominant flow processes operating at the hillslope scale, using a combined macroscale measurement and model development and analysis framework. Irrigation experiments at two steep forested hillslopes were conducted to isolate individual hillslope flow...
