Home range, dispersal, homing and density of Townsend's mole, Scapanus townsendii (Bachman), were studied during 1964 near Tillamook, Oregon. Additional information on the success of marking
and capture techniques and the response of moles to flooding was gathered. This study was initiated to supply information which might aid in the...
The time-honored convention of concentrating aqueous samples by solid-phase extraction (SPE) is being challenged by the increasingly wide spread use of large-volume injection (LVI) liquid chromatography-mass spectrometry (LC-MS) for the determination of traces of polar organic contaminants in environmental samples. Although different LVI approaches have been proposed over the last...
"The Siletz River ... is the only short coastal stream in Oregon inhabited by a run of what are generally thought to be native summer steelhead. Hatchery-reared progeny from Siletz River stock have been released into and have become established in two other Oregon coastal streams, the Nestucca and Wilson...
Post-mortem examinations were performed on 29 deceased Persian kittens from 13 different litters, and 30 deceased Devon Rex kittens from 18 different litters in order to identify gross anatomical abnormalities. Fifteen kittens were stillborn (8 Devon Rex, 7 Persian), 17 kittens died during the first day of life (16 Devon...
While fluorochemicals have been detected all over the world and in wastewater
treatment plants, the effect of wastewater effluent on the receiving waters has not been
evaluated. In the first study, the mass flow of fluorochemicals emanating from
wastewater treatment plants along the Glatt River in Switzerland was evaluated. The...
4-nonylphenol (NP), a surfactant degradation product, is an unregulated, ubiquitous aquatic contaminant and endocrine disruptor, for which aquatic life criteria are currently under development by U.S. EPA. The effects of NP on estuarine amphipods and chinook salmon fry were investigated, and this dissertation reports research into the impacts of NP...
Oregon's minimum stream flow program is intended to protect
certain instream flow values by maintaining sufficient stream
flows to support aquatic life and to minimize pollution. The
increasing demand for consumptive uses of water, as well as certain
deficiencies in the laws, policies, and administration of the program,
bring into...
In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...
Civil engineers are aware of the impacts of structures on the global environment but the environmental impacts of a fire within these structures remains unknown. Fires present a unique hazard as it is difficult to predict the probability of the occurrence and the intensity. Traditional methods to identify the environmental...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
Project AFS 31 Final report The final report of a study to determine whether discrete races of summer steelhead races exist in the Rogue River, and if so to isolate each race in terms of life history and ecological behavior, including such points as time of entry, seasonal positioning and...
Determination of the source and fate of natural (higher plant lipids, marine
lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived
hydrocarbons and oxygenated compounds in the environment was accomplished
using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS)
to characterize or identify molecular biomarkers to be utilized as tracers....
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
This publication consists of reports of projects carried out by
students in the Marine Resource Management Program in the School of
Oceanography at Oregon State University. These studies, sponsored by
the OSU Sea Grant Program and the School of Oceanography, were carried
out during the period 1974 to 1980. The...
