Modeling abiotic influences on disease dynamics for the complex life cycle of the myxozoan parasite Ceratomyxa shasta

Creator:: Ray, Robert Adam
Abstract:: Most parasites and their hosts live in a balance within their environment; however a disease outbreak can occur when either the parasite, host, or environment, are perturbed. Myxozoan parasites are associated with a wide variety of cultured and wild fish populations. Most myxozoans are relatively benign to their vertebrate host;...

Changes in plasma cortisol concentration of juvenile salmonids during stress

Creator:: Strange, Richard Jackson
Abstract:: I investigated changes in plasma cortisol concentration over time in juvenile salmonids subjected to various stressors that might be encountered in their normal life cycle. This work was directed at finding a general indicator for stress in fish that could be used be used to aid fisheries research and management....

Nanotheraputic Platforms to address Chemotherapeutic Challenges in Breast and Ovarian Cancer Treatment

Creator:: Al Fatease, Adel
Abstract:: Utilizing nanocarrier based drug delivery for improving the magnitude of efficacy of chemotherapeutic agents in many diseases has acquired more attention in research applications. It has shown promising results in both preclinical and clinical trials. The Food and Drug Administration (FDA) has approved many of these polymeric carriers, and tens...

Glucocorticoid regulation of salmonid B lymphocytes

Creator:: Tripp, Ralph A.
Abstract:: The in vitro effects of cortisol in regulating salmonid B cell functions were investigated. B cells at three distinct stages of differentiation were examined for cortisol sensitivity. B lymphocyte responses were examined 1) during the early stage of the precursor, 2) during the intermediate stage of differentiation associated with clonal...

B-cell heterogeneity in salmonids

Creator:: Irwin, Michael J.
Abstract:: Salmonid B lymphocytes were stimulated both in vivo and in vitro and shown to produce antibody specific for the immunogen. A passive hemolytic plaque assay was employed to demonstrate B cells producing specific antibody. Characterization of plaque forming cells (PFCs) involved sequential inhibition with a series of graded concentrations of...

The Influence of Scale in a Structured Decision Making Framework for Chinook Salmon Management

Creator:: McDonnell, Kevin N.
Abstract:: The goal of my dissertation was to explore how scale influences stream restoration prioritization strategies for an anadromous species and identify influential uncertainties that exist at different scales. My objectives were to (1) produce a comprehensive review of the Chinook salmon management challenges in California’s Central Valley and identify the...

An economic analysis of alternative water allocations and habitat investments for anadromous fish production, John Day Basin, Oregon

Creator:: Cerda, Arcadio Alberto
Abstract:: This thesis focuses on the economic efficiency of alternative habitat, streamfiow, and land use allocations within a major drainage of the Pacific Northwest. Specifically, productivity of present habitat and streamfiow conditions is evaluated with respect to anadromous fish species (chinook salmon and steelhead trout) in the John Day River Basin,...

Economic analysis of restoration practices to improve water quality and fish habitat of a large river floodplain : a case study of the Willamette River, Oregon

Creator:: Seedang, Saichon
Abstract:: In- stream water temperature is one of the most important environmental factors associated with the decline in salmonid populations and their habitats in the Pacific Northwest. Most ecological restoration practices that attempt to reduce instream temperatures center on replanting or reestablishing riparian vegetation and increasing flows. However, in a large...

Scaling of Hyporheic Exchange Processes and Finding the Intermediate Sweet Spot

Creator:: Becker, Paige Sheridan
Abstract:: Hyporheic zones are important regions that reside below and along the sides of streams. Within this region, several ecosystem services are provided including stream temperature regulation, habitats for a large variety of species, pollutant removal, and nutrient cycling. Exchange between the hyporheic zone and stream occurs across multiple scales, but...
