Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

Creator:: Clark, Darren A.
Abstract:: Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...

Direct and indirect effects of livestock grazing intensity on processes regulating grassland bird populations

Creator:: Johnson, Tracey N.
Abstract:: In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...

Perceptions on Spalted Wood: The Influence of Historic Spalting Patterns and Valuation of Spalted Wood Around the World.

Creator:: Vega Gutiérrez, Patricia T.
Abstract:: During the 1400s – 1600s, spalted wood was an expensive commodity used in marquetry style artworks across primarily Germany and Italy. It fell out of favor during the Industrial Revolution, but is currently experiencing resurgence in popularity with US woodturners. How spalted wood is used, and what types of spalted...

Investigations of the AhR-induced Treg : transcriptional regulation and suppressive mechanisms

Creator:: Rohlman, Diana
Abstract:: The aryl hydrocarbon receptor (AhR) has recently been described as a novel therapeutic target, given the potent suppression of multiple immune-mediated diseases following activation by the prototypic ligand, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). In the parent-into-F1 graft-versus-host (GVH) model, suppression of the cytotoxic T-lymphocyte (CTL) response is associated with the presence of CD25⁺CTLA-4⁺IL-10⁺Foxp3[superscript...

Limitations to Seedling Regeneration on Tropical Forest Restoration Plantations in Northern Thailand

Creator:: Sangsupan, Hathai A.
Abstract:: This dissertation investigated potential ecological limitations to seedling regeneration in young, seasonally dry, evergreen forest restoration plantations in northern Thailand. We explored whether recruitment of colonizing tree species in the restoration plantations can be attributed to seed dispersal mode (i.e. abiotic or animal dispersal) and seed size. We did this...

Contemporary regional forest dynamics in the Pacific Northwest

Creator:: Reilly, Matthew J. (Matthew Justin), 1975-
Abstract:: Recent climatic warming trends and increases in the frequency and extent of wildfires have prompted much concern regarding the potential for rapid change in the structure and function of forested ecosystems around the world. Episodes of mortality in wildfires and insect outbreaks associated with drought have affected large areas and...

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...

Identification and characterization of type III effector proteins in plant-associated bacteria

Creator:: Thomas, William J.
Abstract:: Symbioses between microbes and multicellular eukaryotes are found in all biomes, and encompass a spectrum of symbiotic lifestyles that includes parasitism and disease, commensalism, and mutually beneficial interdependent host-microbe relationships. Regardless of outcome, these symbiotic lifestyles are governed by a complex molecular "courtship" between microbe and potential host. This courtship...

Spalting Fungi : Genetic Identification, Material Interactions and Microscopical Characteristics of Extracted Pigments

Creator:: Vega Gutiérrez, Sarath Mercedes
Abstract:: Spalting fungi show strong potential as natural colorants on a variety of materials, specifically textiles and wood. Four species of spalting fungi are currently utilized in this manner: Scytalidium cuboideum, which produces a red pigment called draconin red, Scytalidium ganodermophthorum, that produces an unknown yellow pigment, and Chlorociboria aeruginosa and...

Health Service Utilization among Medicaid Enrollees in Oregon : Assessing Variation by Level of Rurality

Creator:: Larson, Annie E.
Abstract:: Research Objective: Nearly 60 million people in the United States reside in a rural area. Residents in rural areas have higher rates of chronic disease, risky health behaviors, disability, infant mortality, and age-adjusted mortality than their urban counterparts. Health insurance and access to care mitigate those risks, in part because...
