Simulating Wood Properties in the Context of a Growth and Yield Model for Planted Douglas-fir

Creator:: Osborne, Nathaniel L.
Abstract:: Forest growth and yield models are critical to supporting decision making in forestry, but often lack considerations for wood properties. The feasibility of simulating wood properties in the context of a Douglas-fir individual tree growth and yield model was evaluated. This assessment explored the effect of predicted sapwood width, stem...

Thinning effects on stand and tree growth : different perspectives on same old questions

Creator:: Romero Castaño, Pablo
Abstract:: The search for the stand density that optimizes growth and hence generates the maximum amount of wood is one of the philosopher’s stone in modern forestry. Since scientific methods were applied to forestry, numerous generations of foresters have studied the relations between stocking density and growth, obtaining diverse results and...

Temperature stress, gene expression, and innate immunity at the onset of cnidarian-dinoflagellate symbiosis

Creator:: Schnitzler, Christine E.
Abstract:: The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...

Influence of forest structure and experimental green-tree retention on northern flying squirrel (Glaucomys sabrinus) abundance

Creator:: Holloway, Gillian L., Smith, Winston P., Halpern, Charles B., Gitzen, Robert A., Maguire, Christine C., and West, Stephen D.
Abstract:: In many regions of the world, forest management has shifted from practices emphasizing timber production to more sustainable harvesting that integrates ecological values, including maintenance of biodiversity, wildlife habitat, and ecological goods and services. To this end, management strategies emphasize retention of stand structures that meet the needs of forest-obligate...

Beyond heat or eat : street-level bureaucracy in rural Oregon energy relief

Creator:: Maguire, Jennifer J.
Abstract:: Rising energy costs coupled with the diminishing incomes associated with rural economic restructuring leave an increasing proportion of rural households faced with the heat or eat dilemma--where families must choose between meeting one basic need over another, such as putting food on the table or keeping the heat on. Effective...

Life cycle assessment of algal biofuels

Creator:: Kirby, Bryan L.
Abstract:: This thesis consists of three studies to better understand the environmental sustainability potential for algal-based biofuels. Initially, a comparison of recent life cycle assessments (LCA) of theoretical full-scale algal biofuel facilities was developed. These studies include varying boundaries and scope, functional units, and technology maturity assumptions. The comparison converted results...

Techno-economic analysis of algal lipid fuels

Creator:: Xiang, Xuwen
Abstract:: A techno-economic analysis (TEA) was performed to evaluate the technology, cost, and resource use for algal biofuel production based on today’s economics and technology. The basic goal of this study is to develop a model to calculate the mass and energy balances and costs to produce 10 million gal of...

Assessment of Decentralized Wastewater Treatment System- Potential Impact on Water Quality

Creator:: Chavan, Padmaja Ramesh
Abstract:: Watershed analysis is a method used to collectively characterize ecosystem elements present within a watershed. Wastewater flow and pollutant content help to define the appropriate wastewater treatment system necessary to treat the wastewater within the watershed. Watershed monitoring aids to investigate the potential contamination through analysis of surface waterbodies. Major...

Techno-economic and Life-cycle Analyses of Glucosamine and Lipid Production from Marine Diatom Cyclotella sp.

Creator:: Xiang, Xuwen
Abstract:: Currently the production of biofuel from algae is not economically competitive with petroleum fuel. However, co-production of high-value products may be able to justify the cost of large-scale algae cultivation. The basic goal of this study is to develop a techno-economic analysis (TEA) and Life-cycle assessment (LCA) for the production...

Community Perceptions of Recreation Management and Experiences in the Oregon State University Research Forests

Creator:: Gustavson, Elspeth
Abstract:: Strategic planning for forests subjected to multiple uses is important for management that sustains and balances these many uses. In the wildland urban interface where forests are in the backyards of members of the public who avidly recreate in them, it is also important to include the community in the...
