Multivariate Vegetation Mapping -- Code and Data

Creator:: Henderson, Emilie B.
Abstract:: This data set contains RCode designed for mapping correlated vegetation summary variables via univariate (modified random forest regression) and multivariate (random forest nearest neighbor) methods. It also contains a small vegetation plot dataset to illustrate the type of information needed to support such an analysis.
Resource Type:: Dataset

Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

Pulse reader for ionization chambers

Creator:: Boothe, Gary F.
Abstract:: A pulse reader for ionization chambers has been developed, tested, and calibrated. An insulated gate field effect transistor (IGFET) was used to detect the pulses and Victoreen Model 362 Pocket Chambers were used as ionization chambers. The energy dependence of the Victoreen Model 362 Pocket Chamber was determined to be...

Corn (Zea mays L.) yields as influenced by nitrogen, row spacing and intercropped ryegrass (Lolium multiflorum)

Creator:: Wivutvongvana, Paibool
Abstract:: Two field corn experiments were conducted on a Woodburn silt loam soil near Corvallis, Oregon, in 1972-1973 to investigate the effects of certain soil management practices on the yield and performance of corn (Zea mays L.). Experiment I involved variables that included three corn row spacings (76, 114, and 152...

Synthetic studies of nonadrides

Creator:: Drapela, Nicholas Ernest
Abstract:: An asymmetric approach to the synthesis of byssochlamic acid (1) is described. Regioisomeric enzymatic differentiation is described in the selective hydrolysis of dimethyl ester 30 by porcine liver esterase. Chiral dimethyl ester 42 was prepared by desymmetrization of cyclopentene 34 using porcine liver esterase. A key intramolecular [2+2]cycloaddition-cycloreversion photometathesis of...

A pioneer exotic tree search for the douglas fir region

Creator:: Silen, Roy R. and Olson, Donald L.
Abstract:: After three-quarters of a century of introduction of 152 conifer and broadleaf species, no promising candidate exotic was found for the Douglas-fir region. Growth curves spanning 50 years or longer are figured for many species. Firs, pines, larches, spruces, hemlocks, and cedars originating in northwestern North America had superior growth...

Driving simulation : a mechanism for understanding driver response to mobile barriers in work zones

Creator:: Swake, Joshua
Abstract:: Highway construction projects require temporary changes in roadway characteristics, such as the number of operational lanes, lane path, lane width, shoulder width, and posted speed limit. These modifications which are often temporary in nature have the potential to impact driving performance. Many research efforts have focused on developing standards to...

Recreation Needs of Mountain Bikers at the Whiskey Run Trails in Bandon, Oregon: A Final Report from a 2021 Survey

Creator:: Munanura, Ian E., Parada, Javier A., Phillips, Miles, and Rosenberger, Randal
Abstract:: Objectives This project presents findings from a survey of 409 mountain bikers, including 257 bikers who have been to Whiskey Run and 152 who have not. The survey was conducted in the fall of 2021 by a research team from the College of Forestry at OSU led by Dr. Ian...
