Logging planning, felling, and yarding costs in five alternative skyline group selection harvests

Creator:: Edwards, Richard M.
Abstract:: Alternative silvicultural systems, such as group selections, have recently come into vogue in the U.S. Pacific Northwest in response to political and public pressure against traditional, even-aged silviculture. There is also interest in silvicultural systems for multiple resources. Little is known about planning logistics, operational requirements, and harvest costs for...

Hotspots, mantle plumes, flood basalts, and true polar wander

Creator:: Duncan, Robert A. and Richards, M. A.
Abstract:: Persistent, long‐lived, stationary sites of excessive mantle melting are called hotspots. Hotspots leave volcanic trails on lithospheric plates passing across them. The global constellation of fixed hotspots thus forms a convenient frame of reference for plate motions, through the orientations and age distributions of volcanic trails left by these melting...

Suction cup sampler bias in leaching characterization of an undisturbed field soil

Creator:: Brandi-Dohrn, Florian M., Dick, Richard P., Hess, Mario, and Selker, John S.
Abstract:: An accurate assessment of leaching losses in the vadose zone requires measurement of both solute and water flux to compute flux concentrations (C[subscript F]). Leachate collected at a depth of 1.2 m in 32 passive capillary samplers (PCAPS), which sample soil-pore water continuously at tensions of 0–50 cm H₂O was...

Deployment and Evaluation of a System for Ground-Based Measurement of Cloud Liquid Water Turbulent Fluxes

Creator:: Kowalski, Andrew S., Anthoni, Peter M., Vong, Richard J., Delany, Anthony C., and Maclean, Gordon D.
Abstract:: Direct interception of windblown cloud water by forests has been dubbed “occult deposition” because it represents a hydrological input that is hidden from rain gauges. Eddy correlation studies of this phenomenon have estimated cloud water fluxes to vegetation yet have lacked estimates of error bounds. This paper presents an evaluation...

A simplified three-dimensional model for Martian climate studies

Creator:: Haberle, Robert M., Houben, Howard, Barnes, Jeffrey R., and Vong, Richard E.
Abstract:: We described a simplified physics approach to generating time-varying global wind and temperature fields suitable for conducting transport studies on Mars. The goal is to develop a computationally fast algorithm that will enable long-term simulations of the planet’s climate system. Thus we use a three-dimensional log-pressure global spectral model forced...

Fava bean (Vicia faba L.)

Creator:: Sattell, Robert, Dick, Richard, McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Fava bean is used as a winter or spring cover crop, green manure, silage, forage, hay, and vegetable. It is capable of producing large amounts of dry matter and accumulating large quantities of nitrogen (N), part of which is available to subsequent crops.

Hairy vetch (Vicia villosa)

Creator:: Sattell, Robert, Dick, Richard, Luna, John, McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Hairy vetch is used as a cover crop, green manure, pasture, silage, and hay. It is capable of accumulating large amounts of dry matter and nitrogen. When planted alone as a winter cover crop in annual vegetable rotations, it can provide substantial amounts of nitrogen (N) to a following crop.

Comparison of submersible-survey and hydroacoustic-survey estimates of fish density on a rocky bank

Creator:: Starr, Richard M., Fox, David S., Hixon, Mark Anthony, Tissot, Brian N., Johnson, Gary E., and Barss, William H.
Abstract:: Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through October 1991. The objectives of the study were to determine the proportion of fish...

The ecology and management of bluebunch wheatgrass (Agropyron spicatum) : a review

Creator:: Miller, Richard F., Seufert, Jamie M., Haferkamp, Marshall R. (Marshall Roy), 1942-, and Oregon State University. Agricultural Experiment Station
Abstract:: Agropyron spicatum, considered one of the most important native bunchgrasses in British Columbia, western Montana, the Columbia Basin and the area between the Cascades and Sierras and the Rockies, dominated millions of acres of pristine semiarid grass and sagebrush sites. It produced more herbage than all other associated species in...

Cover crop dry matter and nitrogen accumulation in Western Oregon

Creator:: Sattell, Robert, Buford, Thomas, Murray, Helene, Dick, Richard, McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Cover crop selection and management depend on many factors, among them the cover crop’s ability to accumulate dry matter (i.e., residues) and nitrogen (N). Dry matter provides energy for soil organisms, contributes to soil organic matter, improves tilth, and acts as a sink for nutrients.
