Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...

Sugar transport in strawberry fruit : uptake competition and developmental changes in invertase levels

Creator:: Scott, James Douglas
Abstract:: Mechanisms by which plant organs accumulate photoassimilate are important in determining final sink size and may involve invertase activity. Because strawberry fruit are strong sinks for sugars, changes in invertase levels during development and mechanisms of sugar uptake within the fruit were examined. Fruit from greenhouse-grown, day-neutral strawberries, (Fragaria X...

Landslide hazards in The Dalles, Wasco County, Oregon

Creator:: Sholin, Michael Hugh
Abstract:: Human activity has led to the reactivation of portions of a Pleistocene landslide complex in The Dalles, Oregon. Slope movements are in rocks of the Chenowith formation: agglomerate, conglomerate, tuff breccia, sandstone, and siltstone. Slope movements occur in at least two distinct areas in The Dalles. At one, the shear...

Table Beet Yield and Boron Deficiency as Influenced by Lime, Nitrogen, and Boron

Creator:: Hemphill, Delbert D. Jr, Weber, Michael S., and Jackson, T. L. (Thomas Lloyd), 1922-
Abstract:: Yield, occurrence of root canker (B deficiency), and leaf nutrient concentrations of the Morse strain of ‘Detroit Dark Red’ table beet (Beta vulgaris L.) as influenced by combinations of lime and N, B, and P fertilizers were evaluated in three studies. Greatest total yields and most favorable distribution of root...

Ecology and plant communities of the riparian area associated with Catherine Creek in northeastern Oregon

Creator:: Kauffman, John Boone, Krueger, William C. (William Clement), 1942-, Vavra, Martin, and Oregon State University. Agricultural Experiment Station
Abstract:: A multitude of biotic and physical factors, many of them unique to riparian environments, interacted to form an extremely complex ecosystem along Catherine Creek in the Wallowa Mountains. A total of 258 stands of vegetation representing 60 communities was identified. At least 20 species of mammals and 81 species of...

Evaluating the relative worth of public range improvements to a cow-calf ranching operation through computer simulation

Creator:: Tanaka, John Augustus
Abstract:: A computerized ranch simulation model of an eastern Oregon cattle ranch was tested for its ability to evaluate the economics of public rangeland improvement practices. The model was used to estimate likely impacts of various public policy alternatives for rangeland improvement on the relative profitability of a 400 mother cow...

B-cell heterogeneity in salmonids

Creator:: Irwin, Michael J.
Abstract:: Salmonid B lymphocytes were stimulated both in vivo and in vitro and shown to produce antibody specific for the immunogen. A passive hemolytic plaque assay was employed to demonstrate B cells producing specific antibody. Characterization of plaque forming cells (PFCs) involved sequential inhibition with a series of graded concentrations of...

The effects of low protein diets with varying levels of dietary energy and triticale (var: Flora) on the reproductive performance of medium white turkey breeder toms

Creator:: Nilipour, Amir H.
Abstract:: Three experiments were conducted to determine if a new variety of triticale (Flora) would maintain seminal production of Medium White (MW) breeder toms and to ascertain the minimal dietary crude protein (CP) required by breeder toms. In Experiment 1, 4 dietary treatments with 10 males each, were fed ad libitum...

Technology and the origin of human hemispheric asymmetry

Creator:: Boraas, Alan Sivert
Abstract:: This paper proposes that human asymmetrical hemispheric function originated because of the cognitive requirements of tool-making. The human brain can be considered to be a product of two evolutionary episodes. The first episode was shared with other mammals and resulted in a brain composed of a reptilian complex, paleomammalian and...
