Utilization of the Columbia River Estuary by American shad, Alosa sapidissima (Wilson)

Creator:: Hammann, Mark Gregory
Abstract:: The migrations, distribution, and feeding of American shad, Alosa sapidissima (Wilson), were studied from February 1980 through January 1981 in the Columbia River Estuary, an important rearing zone for young-of-the-year shad. Sampling was performed with purse seine, beach seine, and otter trawl. Adult shad and large numbers of juveniles from...

Propagule sources, disturbance characteristics and the inital establishment of riparian vegetation after debris flows

Creator:: Gecy, Jeanne Leslie
Abstract:: Debris flows are a major cause of disturbance to riparian vegetation. Both observational and experimental studies were used to examine the initial recovery of riparian vegetation after debris flows on headwater streams in the western Cascades of Oregon. My goal was to determine the roles of seedlings and vegetative sprouts,...

A reaction rate determination of aluminum with a microcomputer-based spectrofluorometer

Creator:: Campi, Gregory Louis
Abstract:: The development and optimization of a fluorometric reaction rate method for the determination of aluminum is described. Modifications to existing instrumentation permit automatic monitoring and reporting of measurement conditions. Automatic correction of measured analytical signals is provided if monitored parameters deviate from optimum values. A computer controlled standard addition procedure...

The effect of residue removal and burning on the growth of Festuca longifolia Thuill. and Festuca rubra L. subsp. commutata Gaud. established for seed production

Creator:: Vollmer, Gregory S.
Abstract:: Hard Fescue (Festuca longifolia Thuill.) has potential for in creased turf use but does not respond well to normal seed production management practices in Oregon. Field burning (the normal residue management practice) results in reduced seed yields in commercial hard fescue seed production fields but stimulates seed production in Chewings...

The effects of diisocyanate-polyol resins on the properties of particleboard.

Creator:: Milota, Michael R.
Abstract:: The ability of the resin to deform plastically can be an important factor when considering the mechanical properties of particleboard. Between resin droplets there exists an unbonded region that forms the surface for a crack. When particleboard is deformed stress concentrations develop at the crack tips in the voids. A...

Adsorption of hexavalent and trivalent chromium to a clayey silt soil : batch kinetic and equilibrium studies

Creator:: Bean, Gregory R.
Abstract:: Chromium, an element of widespread use, is toxic in some forms. Improper disposal of waste chromium products has resulted in contamination of many sites throughout the United States, including the United Chrome Products Superfund site in Corvallis, Oregon. A better understanding of chromium chemistry is needed to facilitate the remediation...

The economic feasibility of locating an OSB plant in western Oegon [i.e. Oregon]

Creator:: Wright, Rhonda R.
Abstract:: The development of an OSB (oriented strand board) industry in Western Oregon would prove to be a real boost to the economy of an area that has suffered from the earlier recession of the forest products industry. Past studies have shown that it is technically feasible to produce OSB from...

The relative impact of single vs. multiple agents on the biological control of Tansy ragwort (Senecio jacobaea)

Creator:: James, Rosalind R.
Abstract:: Field experiments were done to test the relative effectiveness of single and multiple biological control agents in reducing weed populations using two insects, the cinnabar moth, Tvria iacobaeae (L.), and the ragwort flea beetle, Lonqitarsus iacobaeae (Waterhouse). These two insects were released for biological control of the biennial weed tansy...
