The thermal characteristics of hydrologically intact Type C and E streams in eastern Oregon

Creator:: Hopkins, Karl T.
Abstract:: Many streams in eastern Oregon are listed as water quality impaired on the basis of water temperature. However, it is often difficult to predict water temperature for these streams even if there are no anthropogenic impacts. We measured air and water temperature and stream characteristics on three Type C and...

Factors affecting semen quality and their effects on the fertilizing ability of broiler breeder spermatozoa using a fluorometric assay

Creator:: Bootwalla, Salim Mohsin
Abstract:: Three distinct studies using an ethidium bromidedigitonin fluorometric assay were conducted to determine if the fertilizing ability of individually caged broiler breeder males (BBM) could be enchanced by nutrition, breeding and semen extender viscosity. The first study evaluated the effects on the spermatozoal quality of BBM by feeding corn-soybean meal...

Evaluation of combining ability in mosquitofish

Creator:: Pongthana, Nuanmanee
Abstract:: Two replications of a half dial lei cross experiment were performed among four inbred lines of mosquitofish, Gambusia affinis. These inbred lines originated from three random-bred stocks: OR, TX and CD. The experiment was conducted as a completely randomized design. Experimental material consisted of parental lines and F₁ populations maintained...

A model for understanding the influence of selective and nonselective harvest on fish populations

Creator:: Hirai, Takayuki
Abstract:: To understand the influence of selective harvesting on the adaptive capacity of fish populations in changing environments, a computer simulation model was developed. In the model, hypothetical populations were composed of five different life histories, which were genetically determined. Each life history type had its own rate of survival and...

Development of performance based test procedures for asphalt mixtures

Creator:: Kliewer, Julie E.
Abstract:: In 1987, Congress authorized a 5 year $150 million dollar research program called the Strategic Highway Research Program (SHRP). SHRP was divided into four major areas, including the asphalt research program. The asphalt research program was divided into six major research contracts, one such contract, SHRP-003A was called Performance Related...

Estimates of genetic variability resulting from single, top, and double cross populations in durum wheat (Triticum turgidum L. var. durum)

Creator:: Abdennadher, Mourad
Abstract:: The success of a plant breeding program depends upon the availability of useable genetic diversity. Such diversity may be enhanced depending on the type of hybridization strategy employed. Segregating progenies resulting from F2 populations, a double cross, and a top cross were compared for the amount of useable genetic diversity...

Duration and rate of grain filling and subsequent grain protein content in selected winter wheat populations

Creator:: Mou, Beiquan
Abstract:: The lack of information regarding the inheritance of the duration and rate of grain filling, and the possible relationship between grain fill and grain protein content in wheat prompted this study. Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late maturing cultivars adapted to Oregon, 'Stephens' and...

Assessment of genetic resistance to strawbreaker foot-rot (Pseudocercosporella Herpotrichoides) in selected winter wheat (Triticum aestivum L.) cultivars

Creator:: Encinas-Mungarro, Andres
Abstract:: Strawbreaker foot-rot is a major limiting factor to cost efficient winter wheat production in the Pacific Northwest. Development of resistant cultivars has been hindered by the lack of adequate levels of genetic resistance and screening techniques which can consistently detect desired genotypes. Studies were conducted to determine if the reported...
