Since the Industrial Revolution, surface ocean pH has declined due to the input of anthropogenically derived carbon dioxide, termed ocean acidification. Examinations of phytoplankton physiology in the face of changing pH are becoming more important as anthropogenically-driven pH decreases in the surface ocean progress (termed ocean acidification). Previous research has...
Fracking and natural gas have been widely studied in public opinion research over the years, but few studies evaluate natural gas export and the perceptions of its associated economic benefits and environmental risks. Since the shale revolution in the early 2000s, the U.S. transitioned from a net natural gas importer...
Engineering design projects are implemented to accomplish a variety of goals in organizations. As the complexity of each project grows, the risk and uncertainty accompanying each project increases as well. As a result project managers must identify potential risks to projects and create plans to avoid realized risks leading to...
In recent years there has been concern over the deterioration and lack of adequate
funding for the US road and highway system. The main goals of this study are to
examine how increasing use of general financing methods effects road quality, to
determine if capital outlay and maintenance expenditure impact...
This classification is an update of the 2004 classification of native vegetation of Oregon by Kagan, Christy, Murray and Titus. As before, this classification lists the native plant associations known to occur in Oregon, and includes both successional and climax vegetation types that were part of the presettlement landscape of...
As juvenile salmon migrate from freshwater into saltwater, physiological changes must occur to allow fish to osmoregulate in the marine environment. Juvenile spring Chinook salmon migrate to the ocean at different time periods, most notably in the fall (August – November; i.e. fall smolts) and spring (February – May; i.e....
