Ablative Pyrolysis of Beetle-killed Trees
The bark beetle outbreak has severely affected the forests across the western U.S., and the infested trees need to be disposed of to avoid falling and minimize wildfire hazards. Thus, we propose to use ablative pyrolysis ... -
Advanced modelling, monitoring, and process control of bioconversion systems
Production of fuels and chemicals from lignocellulosic biomass is an increasingly important area of research and industrialization throughout the world. In order to be competitive with fossil-based fuels and chemicals, ... -
Analysis of the Potential for Diazotrophic Endophytes to Increase Efficiency of Bioenergy Crop Production: Growth promotion effects of the endophytes isolated from Populus trichocarpa and Salix sitchensis
(2013-04-17)<bold>Analysis of the Potential for Diazotrophic Endophytes to Increase Efficiency of Bioenergy Crop Production: Growth promotion effects of the endophytes isolated from Populus trichocarpa and Salix sitchensis</bold> Jenny ... -
Analysis of urban-rural gradients using satellite data
(2000)Growing urban populations has sparked concerns over the urbanization impacts to ecosystems. Gradient analysis has been presented as a method of assessing human impacts on the environment, but few studies have used satellite ... -
Application of multivariate analysis techniques in understanding complex industrial processes: a pulp mill example
(1999)The financial and process benefits of improving the mill fiber line are widely acknowledged. However, process optimization of the fiber line is difficult due to the complex behavior of pulp and paper systems. The dissertation ... -
Assessing Climate Change Vulnerability of Species in Northwestern North America
Climate change affects plants and animals in myriad ways. However, not all species respond similarly, making climate-informed management more difficult. Therefore, managing species in the face of climate change requires ... -
Assessing the Effects of Tropical Land Use Change: A Camera Trapping Study of Terrestrial Peruvian Mammals
Previous research shows that most mammals are reduced in fragmented forests, particularly species averse to human-modified landscapes. Since felids are elusive, sometimes nocturnal, and usually inhabit interior forest away ... -
Assessing the Social Acceptability of Endophyte-Assisted Phytoremediation of Polycyclic Aromatic Hydrocarbons: A Case Study at Gas Works Park
Gas Works Park is a former gas production site that has been converted to a public park. Some of the contaminants have been remediated, however much of the soil is still contaminated with polycyclic aromatic hydrocarbons ... -
Barred Owls and Northern Spotted Owls in the Eastern Cascade Range, Washington
(2013-07-23)Competitive interactions with barred owls (Strix varia) are an important factor contributing to the observed decline in the northern spotted owl (Strix occidentallis caurina) population in Washington. My goal was to develop ... -
Bee-crossed lovers and a forbidden Castilleja romance: Cross-breeding between C. hispida and endangered C. levisecta in prairie restoration sites
Castilleja levisecta (golden paintbrush) is one of Washington's characteristic endangered species, restricted to the Pacific Northwest's disappearing prairies. To establish new populations, C. levisecta was seeded into ... -
Bioconversion of heterogeneous lignocellulosic biomass for sugar production
In order to accomplish large scale utilization of lignocellulosic feedstocks to produce fuels and chemicals, a consistent, inexpensive and stable supply of biomass from a variety of sources will be required. These biomass ... -
Bioconversion of lignocellulosic hydrolysate to acetic acid using Moorella thermoacetica
A systematic study of bioconversion of lignocellulosic sugars to acetic acid by Moorella thermoacetica strain ATCC 39073 was conducted. Four different hydrolysates obtained after steam pretreatment of lignocellulosic biomass ... -
Biology and conservation of the endangered Hawaiian Dark-rumped Petrel (Pterodroma phaeopygia sandwichensis)
(1983)The Hawaiian Dark-rumped Petrel or 'Ua'u is an endangered gadfly petrel that nests in the Hawaiian Islands and ranges throughout the central Pacific. The species was once common in Hawaii, with large colonies located on ... -
Bioremediation of Trichloroethylene: Analysis of the Plant Gene Response to TCE and Characterization of a Novel TCE-Degrading Endophyte
(2012-09-13)Trichloroethylene is a common environmental contaminant. High levels of TCE have the potential to cause liver damage and malfunctions in the central nervous system, and it is considered a likely human carcinogen. More than ... -
Breeding territory settlement patterns and mate choice in a monochromatic tyrannid flycatcher
(2000)What factors influence a male's ability to acquire a high-quality territory and what cues do females use to select a mate in the monochromatic Pacific-slope flycatcher (Empidonax difficilis)? I addressed this question by ... -
Business Activities, Decision-Making, and Barriers to Viability of the Forest Biomass Harvesting Industry in Washington State
(2014-02-24)Using forest biomass- the leftover byproducts of forestry operations- as an energy source potentially presents a win-win alignment of environmental goals, economic growth, and business success. This research explores the ... -
Business Strategies of North American Sawmills: Flexibility, Exports and Performance
(2013-07-23)Lumber production in North America has declined sharply after the housing crisis in the U.S. The weak demand for lumber in the U.S. has been offset by strong international demand, however, some sawmills hesitate to export ... -
Calibration, Validation and Improvement of a Process-based Crop Simulation Model for Hardneck Garlic (Allium sativum L.)
Crop models are powerful tools for assessing climate impacts on crops, assisting breeding and crop management decisions, predicting yield, and providing information for economic and policy decision making. Calibration and ... -
A canopy perspective of community dynamics of an old-growth Pseudotsuga-Tsuga forest
(2000)Old-growth Pseudotsuga-Tsuga forests of the western Cascade Range are characterized by presence of large, old trees of Pseudotsuga menziesii (Mirb.) Franco var. menziesii. Colonizing soon after a stand-replacing disturbance, ... -
Canopy soils, litterfall and litter decomposition in a coastal old-growth temperate rainforest, Washington
(2013-11-14)The canopy of trees has been an unreachable portion for scientific exploration until few decades ago, and the wonders and enigmas that the treetops enclose are increasingly unfolding. This study investigated the canopy ...
