Relationships between fish species distribution and habitat in the Willamette River drainage in western Oregon

Creator:: Kruse, Amy Ellen
Abstract:: The objectives of this study were to (1) describe physical environmental conditions and species composition at several sites along an Upstream/downstream gradient in a number of tributaries of the Willamette River in western Oregon; and (2) identify possible relationships between species distributional patterns and physical habitat parameters using detrended correspondence...

Analysis of Oregon's wholesale demand for California table wines

Creator:: Berkeley, Errol Winston
Abstract:: The passing of the 21st Amendment to the United States Constitution has given to individual states the authority to regulate the sale, distribution and taxation of domestically produced wines, and made the wine trade potentially significant as a means of augmenting state revenues. In the state of Oregon, table wines...

Economic feasibility of mechanical strawberry harvesting in Oregon : estimated private and social benefits and costs

Creator:: Hussen, Ahmed M.
Abstract:: At its peak, Oregon produced 21 percent of the nation's total commercial strawberry production. However, since 1971, Oregon's share of strawberry production has been declining steadily. In fact, for the last three years strawberry production in Oregon constitutes only 8 percent of the nation's total production, which is the lowest...

Substitutional relationships between rainbow trout and pansize salmon : a market demand analysis

Creator:: Queirolo, Lewis E.
Abstract:: The fundamental objective of this analysis was to isolate and identify the factors governing the demand for domestically produced rainbow trout in a representative west coast market, and assess the impact on that demand, if any, of the introduction of pansize salmon. The approach taken in this market demand study...

Estimates of genetic variance and heterosis in F₁ winter x spring barley crosses (Hordeum vulgare, L.)

Creator:: Harrabi, Moncef Mohamed
Abstract:: Four winter and four spring barley cultivars along with their F₁ hybrids were grown on the Hyslop Agronomy Farm near Corvallis, Oregon, a high rainfall site (over 1000 mm annually) located in the Willamette Valley. The experiment consisted of four replications. Ten seeds of each F₁ and parents were seeded...

Sound production in Leperisinus oregonous Blackman and L. californicus Swaine (Coleoptera:Scolytidae)

Creator:: Vernoff, Suellen
Abstract:: Both Leperisinus oregonus and L. californicus are bark beetle species which emerge from Fraxinus latifolia brood logs as sexually immature adults and disperse to living ash. Occasional field observations suggest that, for overwintering and maturation feeding, L. oregonus enter trunks and branches, whereas L.; californicus enter twig crotches, buds and...

A comparison of three systems of phenotypic selection for grain yield in three spring barley populations

Creator:: Hayes, Patrick M.
Abstract:: Concerns regarding the most effective means of evaluating segregating generations of spring barley prompted this investigation. Three methods of selection were considered: bulk, pedigree, and single seed descent. F₆ lines derived by each method were grown in a replicated yield trial. The effectiveness of each method was measured in terms...

Association of selected traits with visual selection for yield in wheat (Triticum aestivum, L. em Thell.)

Creator:: Marciniak, Michael E.
Abstract:: Visual selection for grain yield may be a limiting factor in identifying superior yielding genotypes in a breeding program. This investigation was conducted (1) to compare the effectiveness of visual selection for grain yield by three selector groups representing different levels of plant breeding experience, and (2) to examine the...

Characterization of Triticum turgidum ssp. carthlicum (Nevski) Löve et Löve by discriminant analysis

Creator:: Vieira, Luiz Gonzaga E.
Abstract:: Forty-six morphological characters were used in a study of Triticum turgidum ssp. carthlicum (2n = 28) and specimens of carthlicum-like forms of Triticum aestivum ssp. vulgare (2n = 42). The morphological variation patterns within these groups were examined using stepwise discriminant analysis. These results indicate that specimens studied could be...
