Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

Western Cooperative Spray Project : 1970

Creator:: Westigard, Peter H., Southern Oregon Agricultural Experiment Station, and Oregon State University. Agricultural Experiment Station
Abstract:: This report includes information concerning experimental use of unregistered pesticides or unregistered uses of pesticides. Experimental results should not be interpreted as recommendations for use. Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.

Factors influencing density, distribution, and mesohabitat selection of juvenile wild salmonids and residual hatchery winter steelhead

Creator:: Brignon, William R., Olson, Douglas E., Schaller, Howard A., and Schreck, Carl B.
Abstract:: To best manage Eagle Creek National Fish Hatchery, negative interactions between hatchery salmonids and Endangered Species Act listed wild salmonids in the Eagle Creek Basin need to be minimized. Our objectives were: 1) to compare summer rearing densities in two similar streams, where one stream received a release of hatchery...

Assessment of Feedstock Materials for Producing a Suitable and Cost-Effective Biochar to Use as a Soil Amendment for Northern Highbush Blueberry (Vaccinium corymbosum)

Creator:: Kumari, Pooja
Abstract:: Biochar is a highly porous, carbon-rich residue produced by thermochemical conversion (pyrolysis) of plant biomass and carbonaceous organic materials under oxygen-controlled conditions. Chars produced by this process tend to have high ion-exchange capacities and, when added to soil, increase retention of water and nutrients and improve soil aggregation, porosity, and...

Impact of Dairy Manure Digestate on Microbial Activities in Soil

Creator:: Waggoner, Ashley L
Abstract:: Amendments and fertilizers applied to optimize crop production and improve soil health also supply inputs of soil organic matter (SOM) and nutrients that affect soil microorganisms. In the dairy-intensive Pacific Northwest, dairy manure is stored as slurry mixtures until conditions are appropriate for soil application. During storage, the manure begins...

Do vigorous young forests reduce streamflow? Results from up to 54 years of streamflow records in eight paired-watershed experiments in the H. J. Andrews and South Umpqua Experimental Forests

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...

Aryl acetylene substituent effects : the synthesis and application of biaryls

Creator:: Naffziger, Michael R.
Abstract:: The work described herein details the synthesis and application of biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents on the aryl ring of the terminal acetylenic carbon. From this work, we successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps from inexpensive commercially...

Habitat selection of hatchery and wild juvenile salmonids in Eagle Creek Basin, Oregon

Creator:: Brignon, William R.
Abstract:: To best manage Eagle Creek National Fish Hatchery and minimize any negative impacts that the current hatchery program may be having on Endangered Species Act-listed salmonids in the Eagle Creek Basin, I determined if wild fish are being displaced from preferred habitats by hatchery salmonids Oncorhynchus spp. This thesis had...

Characterizing the neutron spectra in various irradiation facilities within the Oregon State University TRIGA ® Reactor

Creator:: Ashbaker, Eric
Abstract:: The Oregon State University TRIGA® Reactor (OSTR) has a number of irradiation facilities providing a wide range of neutron energies and fluxes. These facilities include a pneumatic transfer tube, a rotating rack, a thermal column, four beam ports, in-core irradiation tubes, a clyogenic gas transfer system and a large vault...

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...
