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, ... -
Alaska Native Perspectives on the Governance of Wildlife Subsistence and Conservation Resources in the Arctic
Wildlife resource management in the Arctic is a collaborative effort across many governments, agencies, extractive industries, environmental organizations, and Indigenous communities. Many governments and environmental ... -
American crow (Corvus brachyrhynchos) thanatology
Given the complexity with which some animals respond to dead conspecifics, how and why non-human animals respond to dead conspecifics is of increasing scientific interest. Among vertebrates, few experimental studies have ... -
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 ... -
Between a Risk and a Hard Place: Scavenging Patterns and Habitat Selection of Carnivores in the Subarctic
Animals must balance the need to acquire sufficient resources against the risk of being consumed by a predator. This challenge is faced by many species which, though predatory, are also subject to predation. The ecological ... -
Bigleaf Maple Decline in Western Washington
Bigleaf maple (Acer macrophyllum Pursh) is a prominent component of the urban and suburban landscape in Western Washington, which lies at the heart of the native range of A. macrophyllum. Acer macrophyllum performs many ... -
Biochemical and thermochemical conversions of short rotation coppice poplar for carbohydrate and fuel production in lignocellulosic biorefineries
The economic success of a potential biorefinery is directly related to the use of economic feasible biomass. Due to high cost, it is unlikely that a wood-based biorefinery would use only whitewood material from conventional ... -
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 ... -
Bioretention Soil Media: Understanding the effects of compost and finding predictors for phosphorus leaching
This study is intended to 1) investigate the effect of compost rate and compost type on bioretention soil media (BSM) performance, and 2) explore possible predictors of phosphorus leaching from bioretention systems. Columns ...
