Microbial Abundance and Community Analysis in Devil’s Hole, Harrington Sound, Bermuda

Creator:: Denman, Carmen C.
Abstract:: Microbial activity within elevated CO2 and oxygen depleted environments changes with density driven stratification overturn in the seasonally anoxic region of Devil’s Hole, Bermuda. The temperature gradient developed during the summer months creates a natural laboratory to study bacterial and virus population density and microbial community dynamics in the anoxic...

The biogeography of Plantago ovata Forssk. (Plantaginaceae)

Creator:: Meyers, Stephen C.
Abstract:: Plantago ovata Forssk. (Plantaginaceae) is a winter annual species which, in North America, inhabits desert and Mediterranean habitats of the southwest United States, northwest Mexico and the Channel Islands of California and Mexico. In the eastern hemisphere P. ovata inhabits desert regions ranging from the Canary Islands, across northern Africa...

Response of needle-litter decomposition and soil nitrogen mineralization to logging-debris manipulation and competing vegetation control in western Oregon and Washington

Creator:: Meehan, Nathan Andrew
Abstract:: Growing societal demand for forest products is pressuring managers to increase productivity from a finite land area, and it is expected that increased supply will come mostly from expansion of intensively managed stands. The USDA Forest Service and numerous collaborators created the Long-Term Soil Productivity (LTSP) network of research sites...

Water quality of runoff from flood irrigated pasture in the Klamath Basin, Oregon

Creator:: Ciotti, Damion C.
Abstract:: Runoff from agricultural lands into Upper Klamath Basin rivers and lakes can cause water quality problems affecting fish and wildlife. Excessive eutrophication in Upper Klamath Lake is linked to high nutrient input (particularly phosphorus) stemming from both lake sediments and watershed tributaries. On a unit area load basis the Wood...

Geneticist L.C. Dunn : politics, activism, and community

Creator:: Gormley, Melinda (Melinda Brooke)
Abstract:: L. C. Dunn (1893-1974) spent most of his scientific career conducting research in developmental genetics as a member of the Zoology Department at Columbia University in the City of New York. He had an accomplished scientific career researching mutations in mice, which earned him respect from other geneticists and scientists....

Thinning aged Douglas-fir : an analysis of mobilization costs and a log bucking strategy for revenue improvement

Creator:: Pilkerton, Stephen J.
Abstract:: Contract harvest operations have become the preferred approach to reducing the largest cost component of timber production through free market competition amongst logging contractors bidding or negotiating for work. The goal of this research was to investigate economic components of harvesting operations not previously studied for steep slope thinning harvests...

Belowground carbon storage and soil organic matter quality following fertilizer and herbicide applications in ponderosa pine plantations along a site-quality gradient in northern California

Creator:: McFarlane, Karis J., 1979-
Abstract:: Belowground carbon (C) storage and quality of soil organic matter (SOM) in forest soils have implications for sustainable forest management and C sequestration, but how these pools change in response to management is poorly understood. I investigated whether fertilization and competing vegetation control, applied alone or in combination early in...

Soil respiration, carbon and nitrogen leaching, and nitrogen availability in response to harvest intensity and competing vegetation control in Douglas-fir (Pseudotsuga menziesii) forests of the Pacific Northwest

Creator:: Slesak, Robert A.
Abstract:: Management practices following forest harvest can affect long-term soil productivity through alteration of soil carbon (C) and nitrogen (N) pools, but processes contributing to change are poorly understood. I assessed effects of three levels of logging-debris retention in combination with initial or annual applications of competing vegetation control (CVC) following...

A genomic and proteomic characterization of the first cultured oligotrophic marine Gammaproteobacterium from the SAR92 clade

Creator:: Mellbye, Brett L.
Abstract:: High-throughput culturing (HTC) consisting of extinction culturing in autoclaved seawater has led to the isolation and characterization of many novel strains of oligotrophic marine bacteria. Strain HTCC 2207 was isolated from the Oregon coast by the HTC method. Phylogenetic analysis based on 16S rRNA gene sequence showed that this strain...

Contributions of riparian vegetation and stream morphology to headwater stream temperature patterns in the Oregon Coast Range

Creator:: Smith, Danielle D.
Abstract:: The role of riparian forests in maintaining temperatures of headwater streams is well established and is a foundation of forest practice rules designed to protect streamwater quality. However, detailed investigation is still needed quantifying specific characteristics of stream systems that affect streamwater temperature including riparian features, stream morphology, and subsurface...
