Power planning efforts in Oregon require accurate information
about hydroelectric potential. Potential uses for Geographic Information
Systems (GISs) are being investigated by three Oregon planning agencies.
This paper presents a method in which a 616 is used to help identify and
reduce uncertainty in previous hydroelectric inventories. Uncertainty with
I offer a personal and prehistoric exploration of the concept of immanence, the principle of a divine force living, remaining, and operating within living creatures, inherent in the human, including the female; a unifying force that connects humans to each other, to nature, and to the earth. I examine the...
Winter wheat is commonly grown in dryland cropping systems in the Pacific
Northwest region of semi-arid eastern Oregon. For agronomic, economic, and
environmental reasons, it is important to understand the long-term sustainability of such
The objective of this study was to evaluate the long-term effects of tillage,
For the last fifty years, meadow foxtail (Alopecurus pratensis L.) has been
invading native flood meadows throughout the Harney Basin in southeastern Oregon.
The expansion of this grass species has been the result of its broad climatic requirements
and ability to withstand drought while thriving in saturated soil conditions for...
A study was conducted to investigate if morphometric facial measurements
could be utilized to differentiate five categorical performance types of Quarter Horses.
The five categories being Western, Halter, English, Reining, and Cutting. The
measurements were collected from 323 registered Quarter Horses representing animals
who ranged in age from one year...
My dissertation focuses on the evolutionary forces that have shaped the chemical signaling system of plethodontid salamanders. Pheromones mediate two phases of plethodontid reproduction: mate attraction prior to courtship and female persuasion during courtship. Substrate-borne chemical signals are believed to play an important role in mate attraction for these animals....
The objective of this study was to evaluate the influence of cow age on grazing
distribution relative to mountain riparian areas. In each of two years, sixty cow-calf
pairs were stratified by age into the following treatments: 1) thirty first calf heifers
(442 kg, body condition score (BCS)=4.5), and 2)...
In June 1988 the Japanese agreed to liberalize their
beef market which had been protected by an import quota
system for twenty-four years. The purpose of this thesis is
to draw conclusions/implications concerning the effect of
the trade agreement (1988 Import Quota Removal Agreement)
upon Japanese beef imports and the...
This study evaluated the recovery of compacted soils on logging
skid trails in clearcuts of the western Cascade Mountains of Oregon.
Soil types included clay, clay loam, silt loam, loam, sandy loam
and loamy sands. Sites ranged in age from five to 38 years since
harvest and 370 to llOOm...
