A case study of positive youth development through environmental conservation
This case study investigates the processes by which Positive Youth Development (PYD) occurs in the Generation Green program of the U.S. Forest Service. Data were gathered using the qualitative methods of participant-observation ... -
A UAS-based approach toward habitat suitability modeling of a rare endemic plant
Predicting habitat and mapping species distributions are important to address declining biodiversity and species extinctions. Habitat suitability models (HSM) predict potential habitat based on a species’ ecological niche, ... -
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 ... -
Accessibility of Urban Greenspace and Its Impact on Health
As the world becomes increasingly urbanized, there is a growing need to better understand the role nature plays in our well-being. A review of the current literature suggests a myriad of potential health benefits can arise ... -
Adapting a process based cold hardiness model to conifers
Plant phenology has been and continues to be impacted by climate change. Process-based modeling of phenology reveals biological characteristics through interpretation of model results and parameter values. This paper aims ... -
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 ... -
An Evolutionary and Ecological Investigation into the Enigmatic Stalked Puffball Genus Tulostoma
Tulostoma is speciose group of stalked puffballs with a high diversity in grasslands and arid environments. This cosmopolitan genus exhibits a high degree of spore morphological variation. Recent molecular analysis suggests ... -
An Exploratory Analysis of Environmentally-Certified Wood Products (ECWPs) in the Residential Leadership in Energy and Environmental Design (LEED) Market: 2018 and 2011
Green building programs incentivize building practices to reduce a building’s impact on the environment and provide healthier spaces for occupants. These programs have gained popularity across the world, and the Leadership ... -
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

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 Carbon Balance for Mass Timbers Beyond the First Life
Forests are an important carbon sink in the global carbon cycle and the carbon they store can be transferred into the built environment via wood products to maximize the forests’ carbon storage potential and mitigate global ... -
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 Feasibility of Siting a Biofuel Refinery in Lewis County, Washington
Currently, 95% of global greenhouse gas emissions in the transportation sector originate from fossil fuels. Biofuels are renewable transportation fuels that can be used in place of traditional transportation fuels like ... -
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 ... -
Backcountry Recreation Modeling and the Extent of Human and Canine Fecal Markers in Subalpine Lakes of Mount Rainier National Park
Alpine lakes are some of the most fragile ecosystems in our national parks and forests and a focal point of backcountry visitation. As a result of climate change, access to these ecosystems is increasing due to annual ... -
Bark beetle and defoliator interactions across Pacific Northwestern forests
The dynamics of irruptive forest insects are changing rapidly in response to climate warming,altering many important ecosystem services and often overwhelming budgetary and logistical resources allocated to mitigate the ...
