Scientists say that climate change is very likely to cause more frequent and more severe weather events. In order to understand how communities respond to changing weather patterns, an exploration of the connection between extreme weather events and climate change awareness, collective action, and policy is warranted. This case study...
This thesis seeks to analyze the relationship between economic growth and environmental quality, in this case measured by forest cover, and analyzes whether this relationship is consistent with an Environmental Kuznets Curve. Additionally the relationship between population density and forest cover was analyzed. A simple theoretical model is derived that...
Weedy rye (Secale spp.) is a weed in the winter-wheat- growing
regions in the Pacific Northwest and surrounding regions. Ethiazin
(4-amino-6-(1,1-dimethylethyl)-3- (ehtylthio)-1,2,4-triazine-5 (4H)-one)
has shown selective control of weedy rye in the cultivar 'Stephens',
(Triticum aestivum). Field, greenhouse, and outdoor pot experiments
were conducted to determine factors influencing selectivity.
Field...
The purpose of this study was to compare the proposed women's college styles for day and evening in selected magazines to the documented apparel of college women from Oregon State College in the 1949-1957 time period. The historic method and visual analysis methods were used to complete this study. An...
Over the last three decades Oregonians have been engaged in a protracted discussion about Marine Spatial Planning. In the last twenty years the discussion has centered on the protection of Oregon’s natural marine resources and has taken on various labels such as marine gardens, conservation areas, marine sanctuary, and marine...
Primary disease gradients of wheat stripe rust, caused by the aerially dispersed fungal pathogen Puccinia striformis, were measured in Madras and Hermiston, OR in the springs of 2002 and 2003. Disease foci were created by inoculating a 1.52m x 1.52m area in each of three replicate field plots (6.1m wide...
The purpose of this study is to summarize the technical information on aggregate mining in Oregon including updates of supply and demand since the last comprehensive forecasting of aggregate demand completed by Whelan (1995). Aggregate is a term that numerous definitions, but as used herein, aggregate is sand, gravel, and...
This study examined the effects of timber harvest and subsoiling on soil physical properties considered important to forest productivity and hydrologic concerns. Ground based mechanical timber harvesting on some soil types can cause soil disturbance including compaction. These effects in turn can influence multiple important soil physical properties that affect...
The capacity for root growth and concentration of indole-3-acetic acid and abscisic acid in the roots of western hemlock seedlings was investigated. The root regenerating capacity (RRC) was defined as the increase in root length, greater than 5 mm, following a 28-day test period. RRC measurements over a two-year period...
