This thesis focuses on the application of the cosmogenic nuclide Beryllium-10 (10Be) in an effort to better constrain the thickness history of the Fennoscandian Ice Sheet (FIS) at the Last Glacial Maximum (LGM) and into the Holocene, as well as begin to answer the long-standing question regarding the age
and...
This research assessed certain specific plant-soil and community
interrelationships in eastern Oregon habitat types dominated by
subspecies of Artemisia tridentata.
The first evaluation described plant-induced soil chemical patterns for Artemisia tridentata plant communities of high perennial
grass-low shrub and low perennial grass-high shrub composition. Soil
concentrations of total nitrogen, organic...
The competition or rivalry for the use of water resources
among economic sectors of the Pacific Northwest and among geographical
regions of the western United States has intensified in recent
years. This rivalry and the long run prospects for water shortages
have increased the demand for research concerning the productivity...
As part of investigations to adapt a suitable grazing system in
western Oregon, this research was designed to monitor the effects of
defoliation treatments on dry matter production, forage quality,
regrowth after defoliation, and species composition of a Lolium
perenne Trifolium subterraneum pasture for three consecutive
growing seasons from 1980...
From the 1860s into the 1920s Edward Sylvester Morse (1838-1925) was a staunch advocate of Darwinian evolution and of science education in the U. S. and likewise for several years in Japan. He had a major impact on the American public’s understanding of evolution, both before and after he became...
Rent-seeking in the U.S. Atlantic sea scallop fishery is described. Resource and trade disputes caused the U.S. fishing industry, including scallopers, to lobby Congress for extended federal jurisdiction in 1977. The sea scallop fishery soon overcapitalized as fishermen captured non-exclusive resource rents. Limited entry was introduced in 1994, but an...

Work occupies a considerable amount of time in most peoples’ lives and can be a source of great pleasure or a source of pain. To enhance peoples’ experience at work, we must first understand how to measure and improve the design of work. This research sought to do just that,...
Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied
during the summers of 2000 and 2001 to determine water heating and cooling
patterns. Hourly temperature data were recorded for air, water, and soil parameters
at four elevations 150m apart on Barney and Stevens Creeks....
