The Environmental, Economic, and Social Factors that Contribute to the Importance of the Pacific Razor Clam (Siliqua patula) Fishery for Oregon Coastal Communities: A Northern Oregon Case Study

Creator:: Baker, Laura C.
Abstract:: Pacific razor clams (Siliqua patula) are narrow oblong bivalves that can be found in sandy habitats along the western coast of the United States, from Alaska (Aleutian Islands) to southern California (Pismo Beach). In Washington state, the razor clam fishery has been documented to be an important contributor to the...

Evidence of buried particulate organic carbon as foundation for heterotrophic carbon metabolism in the hyporheic zone of a montane headwater stream in the H. J. Andrews Experimental Forest, Oregon, USA

Creator:: Serchan, Satish P.
Abstract:: Streams and rivers play a critical role in global carbon (C) cycling by processing, storing, and transporting C. Headwater streams which make up more than 95% of the length of streams and rivers worldwide have disproportionate influence on fluvial C dynamics. The hyporheic zone (HZ) of headwater streams is a...

Genetics of tocopherol composition in sunflower seed

Creator:: Hass, Catherine G.
Abstract:: Tocopherols are plant secondary metabolites that are known collectively as vitamin E. Tocopherol compounds act as potent antioxidants by quenching free radicals and protecting fatty acids from oxidative damage. In humans (in vivo) tocopherols protect membrane lipids from breaking down, while in oils (in vitro) tocopherols protect fatty acids from...

Single nucleotide polymorphism diversity in domesticated and wild sunflowers

Creator:: Freeman, Carrie
Abstract:: Single nucleotide polymorphisms (SNPs) are the most common DNA polymorphisms in plant and animal genomes. SNPs were identified in the allele sequences of up to 12 sunflower (Helianthus annuus L.) genotypes for a genome-wide sample of 81 loci originally mapped using restriction fragment length polymorphism (RFLP) markers. The RFLP loci...

Simple sequence repeat marker development and fingerprinting in Cuphea lanceolata Ait. and C. viscosissima Jacq

Creator:: Karmarkar, Vidyadhar M.
Abstract:: Microsatellites or simple sequence repeats (SSRs) are highthroughput sequence based DNA markers that have been exploited as tools for measuring genetic distance and diversity in evolutionary studies, protection of intellectual property, genetic resource conservation management, cultivar identification and molecular breeding of crop plants. We isolated and sequenced 1095 clones from...

Breeding tools for Cuphea : An updated genetic linkage map and fatty acid mutant candidate gene analysis

Creator:: Powers, Carol Anne
Abstract:: Medium chain fatty acids (MCFAs) are important industrial feedstocks for soaps, detergents and surfactants. Interspecific lines derived from Cuphea lanceolata and Cup hea viscosissima are being domesticated as a temperate source of MCFAs. These species also serve as model organisms for understanding the biosynthesis of MCFAs in seeds. Various markers...

Understanding the economic benefits of tidal wetlands restoration

Creator:: Shaw, Graham R.
Abstract:: Habitat restoration projects are vital for recovering ecosystems, but they can be expensive. One way to help justify the price tag is to value the economic benefits provided by the restored habitat. The issue is that many ecosystem services and the flow of benefits they produce are complex, requiring careful...

The acetohydroxyacid synthase gene family its role in herbicide resistant sunflowers

Creator:: Hawley, Robin M.
Abstract:: Resistance to acetohydroxyacid synthase (AHAS)-inhibiting herbicides has been reported in over 90 weedy species, including wild sunflower biotypes, since the herbicides were developed in 1982. The AHAS gene family in sunflower, consisting of three paralogs AHAS1 , AHAS2, and AHAS3, has been targeted for inducing herbicide resistance. A polymorphism identified...

SCALE 6 (TRITON) Simulations of Fission Product Gamma Line Emissions and their Comparison to Plutonium and Uranium Measurements

Creator:: Sanchez, Timothy J.
Abstract:: Thin foil samples of special nuclear materials (SNMs) were irradiated for 60s using a Mark TRIGA II reactor, and their associated gamma emissions were recorded with a count time of 60s following irradiation. A rapid pneumatic transfer system was used to irradiate the samples in front of beam port #4....

Describing the thermal regimes of two northeastern Oregon streams

Creator:: Raven, Sonja E.
Abstract:: Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied during the summers of 2000 and 2001 to determine water heating and cooling patterns. Hourly temperature data were recorded for air, water, and soil parameters at four elevations 150m apart on Barney and Stevens Creeks....
