An ecosystem service approach to inform reactive nitrogen management in the lower Yakima River Basin, Washington

Creator:: Crowell, Morgan
Abstract:: Spatially explicit ecosystem service valuation (ESV) allows for the identification of the location and magnitude of services provided by natural ecosystems to human activities along with a measure of their significance based upon economic valuation. While ESV has been used to provide new insight into land use management, few studies...

An experimental investigation of the effects of temperature and dissolved oxygen on the growth of juvenile English sole and juvenile Dungeness crab

Creator:: Bancroft, Morgan P.
Abstract:: In the past two decades, occurrences of summertime upwelling-driven low dissolved oxygen (DO) events, or hypoxia, have increased along the northeast Pacific coast. If hypoxic events are severe enough to cause marine species mortality, the areas affected are often called "dead zones." In 2002 and again in 2006, the events...

The effect of reducing microorganisms on the rate of color development in cured meat

Creator:: Kalle, Gurudutt Pandurang
Abstract:: The microorganisms present determine to a great extent the quality of cured meat. Some of them may have unfavorable effects on the color and flavor, whereas others are known to have beneficial effects on these quality factors. Yeasts, bacilli, and streptococci were found to be predominately present in a cover...

Influences of environmental acidification on salmonid reproduction

Creator:: Weiner, Gary S.
Abstract:: Reproduction of salmonid fishes in acidic water was studied using the rainbow trout (Salmo gairdneri). Adult trout were exposed to various levels of hydrogen ion (pH levels 4.5, 5.0, 5.5, and control [6.5 to 7.1]) during the final 6 weeks of reproductive maturation. Reduced survival rates of the progeny of...

International students as educational migrants : east and southwest Asian perspectives

Creator:: Visconti, Lauren A.
Abstract:: Projected to reach one million people next year, international students in the United States are undergoing a transformative educational migration. Moving away from the existing study abroad paradigm is the first step to more accurately understand the lived experience of an educational migrant. Discovering the perceptions of what value an...

Gamma irradiation patterns of Salmonella typhosa, Salmonella paratyphi B, and Salmonella wichita in crabmeat

Creator:: Dyer, John Kaye
Abstract:: Studies were conducted under controlled conditions in order to observe the resulting survival patterns in solid crabmeat of Salmonella typhosa, Salmonella paratyphi B, and SaImonella wichita following individual exposure to various doses of gamma radiation. As shown in their survival curves, these species of Salmonella exhibited in varying degrees a...

A geophysical analysis of the Orozco fracture zone and the tectonic evolution of the northern Cocos plate

Creator:: Lynn, Walter S.
Abstract:: In April of 1974, Oregon State University conducted a geophysical survey of the Orozco fracture zone, a Left-lateral transform fault which offsets the East Pacific Rise off the coast of Mexico near 15°N, 105°W. Magnetic, gravity, bathymetric, and seismic reflection data were collected during a four day period. This survey...

Gamma irradiation inactivation kinetics of medically important bacteria contaminating seafoods

Creator:: Quinn, Dorothy Jean
Abstract:: Gamma irradiation inactivation kinetics were studied using fifteen organisms naturally contaminating seafoods. Survival curves for seven Salmonella, three Shigella, two Streptococcus species and a Staphylococcus, Escherichia and Proteus species were determined using Hartsell's broth and fresh oysters. Also, the Shigella species and one species of Streptococcus, Escherichia and Proteus were...
