Whole system perspective : Steelhead, Onchorhynchus mykiss, glutathione s-transferase as a biomarker of chlorpyrifos exposure

Creator:: Pecore, Rachael G.
Abstract:: Organophosphate insecticides may produce sublethal, adverse effects on salmonid growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an organophosphate insecticide, was detected by the Oregon Department of Environmental Quality in the Hood River and tributaries during March 1999 at levels exceeding state water quality standards in the range of 0.011-0.482 μg/L....

Genetic analysis of BYVD resistance and low temperature tolerance in winter x spring barley crosses

Creator:: Zitzewitz, Jarislav W. von
Abstract:: The development of winter 6-row malting barley varieties is an objective of the OSU program. The program's winter germplasm is quite susceptible to Barley Yellow Dwarf Virus (BYDV). The program recently released the spring 2-row variety Orca, which carries the Yd2 gene for BYDV resistance. The objective of this project...

Resource Type:: Undergraduate Thesis

Field validation of laboratory tests used in screening Port-Orford-cedar for resistance to Phytophthora lateralis

Creator:: Wing, Adam B.
Abstract:: Port-Orford-cedar (POC) (Chamaecyparis lawsoniana (A. Murl.) Parl) is an important tree species native the coastal ranges of southern Oregon and northern California. The tree is a false-cedar in the cypress (Cupressaceae) family and is used for timber and planted as an ornamental. The tree in most of its native range...

Chromium and zinc uptake in Elodea densa and Ceratophyllum demersum : Applications for bioremediation

Creator:: Wilson, Jorie and Moore, James
Abstract:: South American waterweed, Elodea densa (Planch.) Casp., and Coontail Ceratophyllum demersum L., were studied for their potential to take up chromium and zinc and as a possible indicator of arsenic, cadmium, copper, and lead pollution. Plants were collected from the Willamette River in Oregon and exposed for 48 hours to...

Distribution of dissolved, bioavailable PAHs in the lower Willamette River, Portland Harbor, Oregon

Creator:: Visalli, Solyssa Gabrielle
Abstract:: Polycyclic aromatic hydrocarbons (PAH) are common pollutants of aquatic systems in urban environments. Due to their lipophilicity, persistence, toxicity and carcinogenicity, they are chemicals of considerable concern. The Portland Harbor includes a large industrial section with numerous current and historic sources for PAH contamination. Runoff from a large metropolitan area...

Development of viticultural practices to improve winegrape performance : effect of crop level on fruit composition of Pinot noir grapes grown in the Northern and Central Willamette Valley, Oregon

Creator:: Taylor, Patrick
Abstract:: A broad range of factors influence wine grape quality and manipulation of these factors has stimulated interest among grape growers, wine makers, and research scientists alike. One such factor affecting wine grape quality is crop level, particularly for Pinot noir. Since the capacity of a vine to ripen fruit depends...

Suitability of selected enzyme assays as future soil quality indicators

Creator:: Taylor, Anne Elizabeth
Abstract:: Deforestation, intensive agriculture and chemical use all can cause long-lastingn negative impacts on soil health. With all the vital functions that soils perform and the potential for further soil degradation, it is important that standards of soil quality or soil health be implemented. Soil aggregation is considered to be a...

Immunohistochemical localization of cytochrome P450s IA, 2K6, 2K7, 3A65 and 3C1 and expression of P4501A in tumor sensitive and resistant lines of juvenile zebrafish

Creator:: Taylor, Amber
Abstract:: Five new anti-zebrafish cytochrome P450 (CYP) antipeptide polyclonal antibodies were tested for tissue specificity using immunohistochemistry. The antibodies are for the zebrafish CYPs IA, 2K6, 2K7, 3A65 and 3C1. Three of these antibodies were also compared to existing antibodies made against CYP isozymes in rainbow trout (Oncorhynchus mykiss). Individual staining...

Efficacy of entomopathogenic fungi for control of the cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae)

Creator:: Snelling, Jane E.
Abstract:: The cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae) is a serious pest of cruciferous crops (i.e. broccoli, cabbage, turnip, rutabaga) in North America and Europe (Coaker and Finch, 1971; Whistlecraft et al., 1985). The adult flies lay eggs around the base and in cracks at the soil surface around wild...
