Semi-volatile organic compounds and developing organisms : accumulation in California mountain tadpoles in the field and fish embryo exposures in the laboratory

Creator:: Stanley, Kerri A.
Abstract:: The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...

A network approach for the mechanistic classification of bioactive compounds

Creator:: Siebert, Trina A.
Abstract:: Using network architecture to describe a biological system is an effective organizational method. The utility of this approach, which generally applies to qualitative models, is enhanced by the addition of quantitative models characterizing the interactions between network nodes. A chromatophore-based signal transduction network is developed, and the highly interconnected major...

The water and energy dynamics of an old-growth seasonal temperate rainforest

Creator:: Link, Timothy E.
Abstract:: In the Pacific Northwest (PNW), concern about the impacts of climate and land cover change on water resources, flood-generating processes, and ecosystem dynamics emphasize the need for a mechanistic understanding of the interactions between forest canopies and hydrological processes. A detailed measurement and modeling program during the 1999 and 2000...

Characterization of the Zea mays ssp. mays TOUSLED-like kinases

Creator:: Owusu, Ethel Owusuwaa
Abstract:: This dissertation describes the cloning and characterization of the TOUSLEDlike kinases genes of maize (ZmTLKs). The TOUSLED-like kinases (TLKs) are a conserved family of nuclear Ser/Thr kinases in higher eukaryotes. The maize genome has three TOUSLED-like kinase genes (ZmTLK1, ZmTLK2, and ZmTLK3). Based upon sequence similarity, the ZmTLKs are divided...

Influence of previous cattle and elk grazing on the subsequent diet quality and nutrient intake rate of cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav
Abstract:: Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...

Traditional ecological knowledge to develop and maintain fire regimes in northwestern California, Klamath-Siskiyou bioregion : management and restoration of culturally significant habitats

Creator:: Lake, Frank K.
Abstract:: The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...

Genesis of the El Salvador porphyry copper deposit, Chile and distribution of epithermal alteration at Lassen Peak, California

Creator:: Lee, Robert G. (Robert George)
Abstract:: The El Salvador porphyry copper deposit in the Indio Muerto district of northern Chile has been geologically investigated for more than 60 years and provides one of the best bases for understanding similar environments of ore formation elsewhere in the world. Fourteen new zircon U/Pb isotopic ages obtained via in...

Extraction and production of n-3 polyunsaturated fatty acid concentrate from Pacific sardines (Sardinops sagax)

Creator:: Okada, Tomoko
Abstract:: Intrinsic characteristics of Pacific sardines were determined. The lipid content in sardines was initially low (6.79%) in the beginning ofthe season, increased to 22.95% in mid-August, and decreased slightly by the end of September. An inverse correlation (R² = -0.90) was found between lipid and moisture content. Analysis showed that...

Effects of Medicinal Herbs on Contraction Rate of Cultured Cardiomyocyte. Possible Mechanisms Involved in the Chronotropic Effects of Hawthorn and Berberine in Neonatal Murine Cardiomyocyte

Creator:: Salehi, Satin
Abstract:: Herbs have been used for many centuries in diverse civilizations for the treatment of heart disease. Only a few natural supplements claim to have direct cardiovascular actions including hawthorn (Crataegus spp.) and berberine derived from the Berberidaceae family. Several different studies indicate important cardiovascular effects of hawthorn and berberine. For...

Alternative orchard floor management practices, soil quality, nitrogen fertilizeruptake, and apple tree growth and yield

Creator:: McDonald, Sarah Finger
Abstract:: Orchard floor management (OFM) practices can improve soil function and alter the soil biological community. Soil function is dependent on soil forming materials and on management practices but little is known about how OFM affect orchard soil quality, fertilizer N uptake, or tree growth and production. Research plots were located...
