Effects of timing and duration of flooding on phosphorus release in four restored wetlands around Agency and Upper Klamath Lakes, Oregon

Creator:: Stevens, Carla J.
Abstract:: Upper Klamath Lake (UKL) and Agency Lake in south-central Oregon are hypereutrophic due to phosphorus (P) loading from both geologic and agricultural sources in the watershed. Restoring historic lake-fringe wetlands to provide P sinks around the lakes has been accepted as a favorable means of reducing lake P levels and...

Shore protection structures in Oregon : An analysis of demand and the implementation of engineering recommendations

Creator:: Chenault, Carla Diane and Chenault, Carla D.
Abstract:: Stabilization structures are the most commonly used form of shore protection along the Oregon coast. Eighty-five percent of the hard stabilization structures built in Oregon from 1976 – 1999 were riprap revetments. An evaluation was conducted of 143 riprap revetments in the northern three counties of Oregon. Clear trends exist...

The influence of herbivore generated inputs on nutrient cycling and soil processes in a lower montane tropical rain forest of Puerto Rico

Creator:: Fonte, Steven J.
Abstract:: The role of insect herbivores in the nutrient cycling dynamics of forest ecosystems remains poorly understood. Although past research in herbivory has focused primarily on the deleterious effects that insects can have on tree growth and mortality, the overall effects of herbivory are more complex. Herbivores have the potential to...

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...

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...

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...

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...

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...

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...
