An edaphic study of the Mt. Pisgah Arboretum water garden, Coast Fork of the Willamette River

Creator:: Bergen, Cameron Francis
Abstract:: Wetlands are widely identified as providing important and fundamental processes valuable for maintaining ecosystem health and diversity. Located in the southern Willamette Valley, the Mt. Pisgah Arboretum contains some valuable remaining wetland habitat along the Coast Fork of the Willamette River. One goal of the Mt. Pisgah Arboretum is "to...

Geographic variation in genetic and meristic characters of coastal cutthroat trout (Oncorhynchus clarki clarki)

Creator:: Williams, Thomas Herbert
Abstract:: Understanding how populations within a species interact across various geographic and temporal scales is fundamental to developing appropriate conservation strategies. I examined the geographic variation in genetic and meristic characters of coastal cutthroat trout (Oncorhynchus clarki clarki) based on approximately 1,400 fish sampled from 54 populations spanning their distributional range...

Conservation of Sidalcea nelsoniana through habitat management : effects of burning, mowing, and altered flooding regime on a rare Willamette Valley perennial

Creator:: Bartels, Marilynn R.
Abstract:: Active habitat management plays a key role in the preservation of native ecosystems and rare species, especially in the Willamette Valley of Oregon, where natural succession to woodlands threatens the few wetland prairies remaining after 150 years of agriculture and urbanization. Sidalcea nelsoniana, listed as threatened under the federal Endangered...

The gene-ecology of Crepis nana Richardson and Crepis elegans Hooker in Arctic and Alpine North America

Creator:: Legge, Allan Herbert, 1942-
Abstract:: A gene-ecological transplant study was made on populations of the Crepis nana and C. elegans complex from the Arctic and Alpine of North America. Transplants were collected from the Brooks Range, Eagle Summit, and Alaska Range in Alaska, the Rocky Mountains in Alberta, the Olympic Mountains in Washington, the Wallowa...

Soil biochemical measures as ecological indicators across agricultural and forest ecosystems of Oregon

Creator:: Knight, Timothy R.
Abstract:: A variety of soil properties have been proposed and tested as potential indicators of soil quality. This study was conducted in an effort to produce a standardized soil quality index for systems in Oregon. Soils in both forested and agricultural systems were sampled in a wide variety of locations, climates,...

Watershed response to western juniper control

Creator:: Deboodt, Timothy L.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

The relationship between the cerebral lateralization for Arabic language and achievement in science

Creator:: Hafez, Abdullah Ibrahim M.
Abstract:: The major purpose of this study was to test the relationship between students' cerebral lateralization for the Arabic language and their achievement in science. A secondary purpose was to investigate handedness as a factor in that relationship. The experiment was conducted in the City of Jeddah, Saudi Arabia, using dichotic...

Investigation of Iron Passivity and Chloride-induced Depassivation in Alkaline Electrolytes using Reactive Force Field Molecular Dynamics (ReaxFF-MD)

Creator:: Dormohammadi, Hossein
Abstract:: The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...

Experimental Investigation of the Effects of Embedded Rebar, Cracks, Chloride Ingress and Corrosion on Electrical Resistivity Measurements of Reinforced Concrete

Creator:: Morales, Monica
Abstract:: The effects of steel reinforcement, chloride-induced corrosion initiation, cracking and delamination on the electrical resistivity measurements using the Wenner probe technique were studied experimentally on custom-designed reinforced concrete slabs. Investigation parameters included (1) probe configurations with respect to rebar mesh, (2) rebar density, (3) epoxy coating on the rebar, (4)...

Some aspects of Western religious thought and man's use of land

Creator:: Bryant, Robert Edman
Abstract:: This study examines a limited number of selected themes in Judeo-Christian, or Western, religious thought and their implications for man's use of land, with the objective of discovering the influence of Western religion on attitudes toward nature and land. Five themes are examined: dominion of man; stewardship; contempt for, and...
