Effects of input and redistribution processes on in-stream wood abundance and arrangement in Lookout Creek, western Cascades Range, Oregon

Creator:: Dreher, David Marshall
Abstract:: This study explored how selected input and redistribution processes affect the amount and arrangement of in-stream wood within the 64 km2 Lookout Creek watershed in the Andrews Forest, western Cascade Range, Oregon. A longitudinal inventory of in-stream wood was conducted over approximately 20 km of stream length in 2nd to...

A review of the Lepturinae (Coleoptera: Cerambycidae) of the Pacific Northwest, with special attention to the elderberry longhorn beetle, Desmocerus Dejean

Creator:: Schapker, Philip A.
Abstract:: Here presented is a photographic catalogue, a key, and literature review for the 35 genera and 90 species of lepturine longhorn beetles (Cerambycidae: Lepturinae) found in the Pacific Northwest. Several nomenclatural changes, recognized by the global taxonomic community, but previously unknown to North American authors, are adopted, and one new...

Simultaneous equation estimation for individual tree growth in young Southern Oregon and Northern California conifer plantations

Creator:: Hamann, Jeff D.
Abstract:: This thesis presents methods for obtaining asymptotically efficient and consistent parameters and variance estimates for simultaneous equations in a forest growth modelling context. Ordinary Least Squares (OLS), Seemingly Unrelated Regressions (SUR), Two-Stage Least Squares (2SLS) and Three- Stage Least Squares (3SLS) are presented for linear models. The variables, model types...

Development of Douglas-fir log quality, product yield, and stand value after repeated thinnings in western Oregon

Creator:: Christensen, Glenn A.
Abstract:: Forest managers are beginning to take an interest in management of young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in Western Oregon and Washington. Studies have established the relationship between growth and levels-of-growing-stock but few have established a link to wood quality and value. This study used data collected from a long...

Distribution and growth of advance Douglas-fir regeneration in commercially thinned stands in the Oregon Coast Range

Creator:: Beer, Louis W.
Abstract:: This study examined the abundance, size, growth, and age of advance regeneration Douglas-fir, beneath an eighty year-old overstory at a single site on plots subjected to different overstory thinning treatments. Treatments consisted of keeping overstory basal area within upper and lower limits for periods of 12-17 years which, depending upon...

Optimization of feeding schedules for coho salmon in the hatchery environment

Creator:: Corey, Philip David
Abstract:: A growth model is developed for coho salmon which accounts for temperatures and feeding rates typically encountered in fish hatchery operation. Feeding rates utilized by the model ranged from maintenance to maximum utilizable rations. The model is derived from an empirical equation for maximum growth rate, and a theoretical equation...

The Winners and Losers of Sarbanes-Oxley

Creator:: Bailey, Derek
Abstract:: As a result of numerous financial scandals at the turn of the 21st century, Congress passed the Sarbanes-Oxley (SOX) Act of 2002, requiring all publicly-listed companies to comply with regulations aimed at reducing the amount of material misstatements in the financial statements, both frauds and errors. Although the costs of...

Advances in Freshwater Cyanobacterial Genomics

Creator:: Brown, Nathaniel M.
Abstract:: Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

Biophysical properties of the turnip yellow mosaic virus explored by coat protein mutagenesis

Creator:: Powell, Joshua D.
Abstract:: Plant viruses have been instrumental in our understanding of the biophysical properties pertaining to non-enveloped icosahedral virus particles. A substantial amount of research has been performed over five decades on Turnip yellow mosaic virus (TYMV), arguably one of the most extensively studied icosahedral plant viruses and the type-member of the...

Bioinformatics applied to freshwater cyanobacterial blooms and cyanophage

Creator:: Schwartz, Andrew D.
Abstract:: Freshwater cyanobacterial blooms are a nuisance and health threat in the Pacific Northwest. The accepted methods of characterizing these blooms by microscopic cell counts cannot differentiate between toxic and non-toxic strains of the cyanobacterium Microcystis. Also, there is limited understanding of freshwater cyanophage that may control bloom dynamics. In order...
