The biology and control of reed canarygrass (Phalaris arundinacea L.) on irrigation ditchbanks

Creator:: Comes, R. D. (Richard Durward), 1931-
Abstract:: Reed canarygrass (Phalaris arundinacea L.) is a desirable pasture grass on wet areas in the Northern United States and Southern Canada, but it is a serious and troublesome ditchbank weed in the Pacific Northwest and Rocky Mountain States. The purpose of this study was to learn more about the development,...

An ecological study of Diatomovora amoena, an interstitial acoel flatworm, in an estuarine mudflat on the central coast of Oregon

Creator:: Thum, Alan Bradley
Abstract:: The distribution and abundance of the interstitial acoel turbellarian, Diatomovora amoena Kozloff, 1965 was studied in an estuarine intertidal sand flat in Yaquina Bay, Oregon, from May 1970 through May 1971. Monthly measurements of biological (organics, sulfides, chlorophyll, and carotenoids), pore water (salinity, pH,oxygen, and temperature), and sediment (fine sediment...

Model and procedure for determination of strength and stiffness of wood studs

Creator:: Fernandez, Virgilio Asuncion
Abstract:: Elasticity properties of wood studs are essential inputs for the structural analysis of wood-stud wall systems. A theoretical procedure was developed to determine the probability distributions for the deflection-load relations of stud samples. The procedure is based on the finite element analysis and a Monte- Carlo type simulation and accounts...

Population dynamics of the Douglas-fir cone moth, Barbara colfaciana (Kft.) (Lepidoptera:Olethreutidae)

Creator:: Nebeker, T. Evan
Abstract:: A population of the Douglas-fir cone moth, Barbara colfaxiana (Kft. ), was studied on the Buckhead Seed Production Area, Oakridge, Oregon, during 1971 and 1972. A method of estimating cone and insect populations is presented. Factors contributing to the mortality of B. colfaxiana are discussed, with resinosis being the critical...

The effect of soil acidity and lime placement on root growth and yield of winter wheat and alfalfa

Creator:: Kauffman, Marvin Dean
Abstract:: The application of lime to an acid Nekia soil significantly increased the yield of winter wheat and alfalfa in a field experiment. Crop yields maximized when the lime was partially mixed into the surface four inches of the soil. Thorough mixing of the lime into the surface six inches of...
