Evaluation of differing anti-predator strategies of three juvenile north Pacific flatfish species

Creator:: Lemke, Jena
Abstract:: Pleuronectid flatfish are generally thought to utilize stereotypical anti-predator behavior to reduce encounters with potential predators, including burial, maintaining a low profile on the bottom, cryptic coloration, and reduced activity. However, a series of laboratory experiments demonstrate significantly different predation rates on juvenile (Age-0) English sole (Parophrys vetulus), northern rock...

Habitat associations and determinants of refuge use in post-settlement lingcod (Ophiodon elongatus)

Creator:: Petrie, Megan E.
Abstract:: Lingcod are an overexploited fish species in the Pacific Northwest and although there has been extensive study of the habitat requirements of adults, particularly during spawning, relatively little is known regarding the habitat requirements of post-settlement juveniles. Many juvenile fish use structural components of habitat to alleviate the risk of...

The Impact of Corporate Social Responsibility on Mergers and Acquisitions

Creator:: Morgan, Scott M.
Abstract:: This study examines the effects of corporate social responsibility (CSR) on merger and acquisitions (M&A). Using data from Kinder, Lyndeberg, and Domini (KLD) Research Analytics and Thomson’s Securities Data Corporation’s (SDC) Platinum Database, we empirically test if CSR scores effect a firm’s propensity to pursue M&A activity. Specifically, I examine...

The Maturest Deliberation : Colonial Pennsylvania Currency in Depression and War

Creator:: Borden, John F.
Abstract:: The purpose of this study is to review Pennsylvania's use of paper money through two distinct periods: the first seven years of currency issues starting in 1723 and concluding in 1730, and the second period encompassed by the French and Indian War in 1755-63. They represent two significant periods affecting...

Comparison of the water relations characteristics of woody plants in western Oregon

Creator:: Davis, Kent J.
Abstract:: I studied the water relations traits, twig conductivity, C'3 isotopic composition, and wood density of three conifer and five angiosperm species in western Oregon. This study took place from spring 2002 to fall 2003 on four sites. Species were selected to represent the diversity of drought tolerance of woody plants...

Modeling protein structure at atomic resolution

Creator:: Berkholz, Donald S.
Abstract:: This thesis includes three studies involving different aspects of modeling protein structure. The first study illustrates the levels of insight available from atomic-resolution protein structures. The second study derives general trends of protein geometry from atomic-resolution structures and shows their implications for modeling. The third study creates a model of...

Bioenergetics-based predator-prey relationships between piscivorous birds and juvenile salmonids in the Columbia River estuary

Creator:: Lyons, Donald E.
Abstract:: This dissertation focuses on the predator-prey relationship between two species of avian predators, Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus), and one of their important prey types, juvenile salmonids (Oncorhynchus spp.), in the Columbia River estuary of Oregon and Washington states during the period 1998 – 2007. I...

Design and Modeling Techniques for Impedance Based Flow Cytometry

Creator:: Dawes, Jacob
Abstract:: Microfluidic devices have enabled lab-on-a-chip (LOC) systems that allow for complex sample analysis and preparation in a compact form factor. One technology that may benefit from a microfluidic approach and further miniaturization is flow cytometry. Flow cytometry is an analysis technique for enumerating and characterizing populations of cells; this is...

Chronic exposure of rodents to indole-3-carbinol and 3,3'-diindolylmethane : implications for drug metabolism, chemoprevention and human health

Creator:: Leibelt, Dustin A.
Abstract:: Indole-3-carbinol (I3C) is a naturally occurring plant alkaloid, found in significant concentrations in cruciferous vegetables such as broccoli and Brussels sprouts. I3C is an unstable compound that undergoes rapid oligomerization in an acidic environment to form higher order condensation products (I3C-ACPs), such as 3-3'-diindolylmethane (DIM). Both I3C and DIM are...

Characterizing the Spread and Consequences of Mycoplasma ovipneumoniae on Bighorn Sheep (Ovis canadensis) in the Northern Basin and Range Ecosystem

Creator:: Spaan, Robert S.
Abstract:: North American bighorn sheep (Ovis canadensis) have experienced significant declines and population extirpations due to novel pathogens such as Mycoplasma ovipneumoniae. This disease continues to limit the population restoration of bighorn sheep. Therefore, understanding the demographic consequences of pathogen presence and the risk of contact between bighorn populations and potential...
