A comparison between the LESA model and the marginal lands criteria of Senate Bill 237 : Linn County, Oregon

Creator:: Holoch, Richard D.
Abstract:: Marginal agricultural and forest lands are currently a focus of concern for public land use agencies in Oregon. Two alternatives for evaluating marginal agricultural lands are the Land Evaluation and Site Assessment (LESA) model of the U.S. Soil Conservation Service and the marginal lands criteria of the 1983 Oregon Legislature's...

Detection of 2,4-D herbicide damage using ground-based measurements : implications for remote sensing

Creator:: McCreight, Richard W.
Abstract:: Spectral patterns of three brush species under the influence of herbicide treatment were investigated to evaluate the effectiveness of monitoring forest vegetation management using ground-based and remote sensing techniques. Foliage of Pacific rhododendron (Rhododendron macrophyllum D. Don), golden chinkapin (Castanopsis chrysophylla Dougl.), and hairy manzanita (Arctostaphylos columbiana Piper) sprayed with...

Improving a sampled-data circuit simulator for Delta-Sigma modulator design

Creator:: Hayward, Roger D.
Abstract:: Delta-Sigma Modulator-based Analog-to-Digital converter design is an active area of research. New topologies require extensive simulations to verify their performance. A series of improvements were made to an existing circuit simulation package in order to speed the simulation process for the designer. Various examples of these improvements are presented in...

Seasonal and diurnal variation in internal moisture stress of mature Douglas-fir

Creator:: Cleary, Brian D.
Abstract:: The internal moisture stress of Douglas-fir was determined on foliage collected in the Siskiyou Mountains of southwestern Oregon. Internal moisture stress integrates both climatic and edaphic environmental effects as they influence a plants moisture regime. In this study two laboratory techniques were modified to permit stress measurements to be taken...

Incorporation of diet information derived from Bayesian stable isotope mixing models into mass-balanced marine ecosystem models : a case study from the Marennes-Oléron Estuary, France

Creator:: Pacella, Stephen Roger
Abstract:: This thesis presents two related studies on the methodology for creating, and subsequently analyzing, an inverse food web model of an intertidal seagrass bed. The first study (Chapter 2) describes, for the first time in the literature, a method for incorporating isotopic information gained from Bayesian mixing models into an...

Purine deposition in the skin of juvenile coho salmon, Oncorhynchus kisutch

Creator:: Staley, Kathryn Boyer
Abstract:: This study was undertaken to quantitatively evaluate the relationship between silvering of the skin of juvenile coho salmon, due to the deposition of the purines guanine and hypoxanthine, and adaptation to seawater. It was hypothesized that maximum purine deposition occurs at the time these fish normally enter seawater, that the...

Hydroxyindole-O-methyltransferase (HIOMT) activity in the pineal of chinook salmon (Oncorhynchus tshawytscha)

Creator:: Birks, Eric K.
Abstract:: C-methyltransferase (HIOMT) in chinook salmon (Oncorhynchus tshawytscha). Various body tissues, as well as several morphological brain divisions were tested for the presence of HIOMT. Activity was found in the retina, the dorsal portion of the diencephalon, and in the pineal gland of chinook. However, the activity was significantly higher in...
