Wetlands are productive ecosystems providing many ecosystem services. Many regulatory agencies recognize the need to protect and preserve wetlands. However, some impacts may be unavoidable. Under those circumstances, compensatory wetland mitigation may be necessary to offset adverse impacts to wetlands. The U.S. Army Corps of Engineers and the New York...
The waterborne, myxozoan parasite Ceratonova shasta is endemic to the Pacific Northwest and can be lethal to its secondary salmonid host, including the culturally, economically, and recreationally important spring Chinook salmon (Oncorhynchus tshawytscha) of the Deschutes River, OR. Previously described genotypes of C. shasta exhibit specificity with their salmonid hosts....
The antibiotics, streptomycin sulfate and oxytetracycline, are used widely for fire blight suppression in the Pacific Northwest region of the United States. The efficacy of streptomycin, however, is compromised by widespread streptomycin-resistance in E. amylovora populations, and oxytetracycline is only partially effective. Consequently, for several years, the aminoglycoside antibiotic, kasugamycin...
In this thesis, we present semantic equivalence rules for an extension of the choice calculus and sound operations for an implementation of variational lists. The choice calculus is a calculus for describing variation and the formula choice calculus is an extension with formulas. We prove semantic equivalence rules for the...
The overall purpose of this research is to assess the Oregon public's capacity to address water resources disturbances through civil society. According to scientists and resource managers, Oregon's water resources are over taxed and at risk, with future projections placing additional stress from climate change and population growth. Oregon's 2009...
The goal of this analysis is to use the social construction framework to determine 1) whether the Oregon Drug Take Back Program stakeholder group can design a public policy that will ultimately reduce water contamination from the improper disposal of unused pharmaceuticals from the general public, and 2) use the...
Ligand activation of the aryl hydrocarbon (AHR) has profound effects upon the immunological status of the gastrointestinal tract, establishing and maintaining signaling networks, which facilitate host-microbe homeostasis at the mucosal interface. However, the identity of the ligand(s) responsible for such AHR-mediated activation within the gut remains to be firmly established....
