This study analyzes and compares alternative methods of valuing nonmarket goods. Using a 1985 study of Rogue River non-commercial whitewater recreationists, benefit estimates of recreational use for this lottery-rationed river are derived using the zonal travel cost method (TCM) and the contingent valuation method (CVM). Two different techniques of the...
Hatchery-reared steelhead (Oncorhynchus mykiss) often have lower fitness than natural-origin fish when spawning in the wild. Fitness loss in hatcheries is partly due to genetic adaptation to captivity (domestication), but the underlying selection pressures driving adaptation remain unknown. Circumstantial evidence suggests that adaptation to hatcheries is accelerated when fish are...
This publication recommends management practices for controlling diseases and insects. This pest management guide was prepared for the home gardener. It doesn’t meet the exacting requirements of the commercial fruit grower. Many fungicides and insecticides are available, which, when used according to the label directions, are effective in managing diseases...

In 1988 the Tualatin River was designated 'water quality limited' by the Oregon Department of Environmental Quality. Three sources of pollution: urban point source, forestry non-point source and agricultural non-point source pollution were considered to contribute unacceptable levels of nutrients (phosphates and ammonium nitrates) to the river. Since a significant...

Realistic hindcast of the Columbia River estuarine-plume-shelf circulation in summer
2004 using the Regional Ocean Modeling System nested within the Navy Coastal Ocean
Model (NCOM) is quantitatively evaluated with an extensive set of observations. The
model has about equal skill at tidal and subtidal properties. Tidal circulation and water
properties...
A new planktonic ecosystem model was constructed for the Eastern Bering Sea based on observations from the 2007–2010 BEST/BSIERP (Bering Ecosystem Study/Bering Sea Integrated Ecosystem Research Program) field program. When run with forcing from a data-assimilative ice-ocean hindcast of 1971–2012, the model performs well against observations of spring bloom time...
