Home range, dispersal, homing and density of the Townsend mole Scapanus townsendii (Bachman) near Tillamook, Oregon

Creator:: Giger, Richard D.
Abstract:: 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...

Trace analysis of environmental matrices by large-volume injection and liquid chromatography-mass spectrometry

Creator:: Busetti, Francesco, Backe, Will J., Bendixen, Nina, Maier, Urs, Place, Benjamin, Giger, Walter, and Field, Jennifer A.
Abstract:: 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...

Siletz River summer steelhead study

Creator:: Weber, Walter G., Fortune, John D., Jr, and Oregon. Wildlife Commission
Abstract:: "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...

Gross causes of neonatal mortality in Devon Rex and Persian kittens

Creator:: Omoto, Holly
Abstract:: 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...

Determination of fluorochemicals in waste-dominated aqueous systems

Creator:: Huset, Carin A.
Abstract:: 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...

Accumulation and effects of 4-nonylphenol in chinook salmon fry and their estuarine amphipod prey

Creator:: Hecht, Scott A.
Abstract:: 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...

Patterns of water resource decision-making: minimum stream flows in the Willamette Basin

Creator:: Griffith, Glenn Edwin
Abstract:: 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...

Zero kinetic energy photoelectron spectroscopy of polycyclic aromatic hydrocarbons

Creator:: Zhang, Jie
Abstract:: 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...
