Phylogeny and Evolution of Gall-Associated Plant Pathogenic Bacteria

Creator:: Davis, Edward W., II
Abstract:: Gall-associated phytopathogens have unique evolutionary histories that haveshaped both their modes of infection and genomic structures. Pathogenicity of the gall-associated plant pathogens of the Rhodococcus, Agrobacterium, and Rathayibactergenera is mediated by horizontally acquired virulence loci. The relative ease of gainand loss of the virulence loci has confounded accurate characterization of...

How Does Climate Change Adaptation and Carbon Price Policy Affect Forested Landscapes? An Empirical Analysis of Forest Management under Climate Change on the U.S. West Coast

Creator:: Hashida, Yukiko
Abstract:: Private forest landowners can adapt to climate change by altering their timing and intensity of harvests, by changing thinning or fertilizing activities, and by altering the tree species growing on their land. The well-being of humans is closely tied to the ecosystem services that forests provide as both market and...

Social Evolution and Regulatory Architecture of Pseudomonas aeruginosa Quorum Sensing

Creator:: Asfahl, Kyle L.
Abstract:: Cell-cell communication in bacteria is understood to facilitate the coordination of population-wide cooperative behavior in the form of concerted gene expression. The opportunistic pathogen Pseudomonas aeruginosa uses such a communication mechanism to regulate a large group of genes important to virulence strategies in this bacterium. This general mechanism of communication...

Characterizing the Plant-Associated Symbionts, Rhodococcus and Agrobacterium

Creator:: Fuller, Skylar L.
Abstract:: Symbioses are a spectrum of interactions between organisms living in closeassociation. These intimate interactions range from mutualism, in which bothorganisms benefit, to parasitism, where one organism benefits at the expense ofthe other. Horizontal gene transfer is the acquisition of genes independent ofvertical transmission and demonstrably promotes the transition of bacteria...

Trade-offs in a pathogen-rich world : genetic and maternal drivers of variation in costly resistance and immunity in African buffalo (Syncerus caffer)

Creator:: Tavalire, Hannah F.
Abstract:: Disease acts as a powerful selective force in natural systems, driving the rapid evolution of resistance in the host. In the face of a myriad of pathogenic challenges in natural systems, hosts must balance the energetic needs of maintenance and reproduction with costly resistance mechanisms. In this dissertation I will...

The Fitness Costs and Regulatory Strategies of Cooperative Siderophore Production in Pseudomonas

Creator:: Sexton, David
Abstract:: Cooperative behaviors in bacteria are increasingly appreciated for their relevance to microbial ecology and utility as model systems for social evolution. One example is the secretion of siderophores, a structurally diverse group of compounds that chelate extracellular iron. Siderophore production is considered cooperative because the benefits can be shared with...

Measuring Health Beliefs About UV Exposure Among Oregon College Students

Creator:: Julian, Anne K.
Abstract:: Exposure to ultraviolet (UV) radiation is a primary cause of melanoma and non-melanoma skin cancer and thus represents a critical public health concern. Skin cancer risk behavior research lacks an instrument designed to assess health beliefs about UV exposure that may increase skin cancer risk by increasing risky UV exposure...

Educational Migration in Indonesia : An Ethnography of Eastern Indonesian Students in Malang, Java

Creator:: Foertsch, Christopher R.
Abstract:: This research explores the experience of the growing number of students from Eastern Indonesia who attend universities on Java. It asks key questions about the challenges these often maligned students face as ethnic, linguistic, and religious minorities exposed to the dominant culture of their republic during their years of education....

The Responses of Slope-spawning Flatfish to Environmental Variability in the Eastern Bering Sea

Creator:: Vestfals, Cathleen D.
Abstract:: When adult spawning and juvenile settling locations of marine fishes are geographically separated, their early life history stages must rely on transport and their own behavior to move them toward suitable habitats for successful recruitment to the juvenile phase. Variations in climate may reduce the availability of spawning and juvenile...

Determination of Trade-offs between Wetland Ecosystem Services in an Agricultural Landscape

Creator:: Garrison, Stacey L.
Abstract:: Wetland restoration mitigates effects of agricultural development on water quality, flooding, and habitat loss. Multi-objective optimization for wetland locations and sizes has not included objective functions for water quality, hydrology, and habitat in unison, limiting analysis of trade-offs among these ecosystem services. This study establishes two methods to improve the...
