Land management with ecological and economic objectives : developing a production possibility set of wildlife species persistence and timber harvest value using simulated annealing

Creator:: Calkin, David E.
Abstract:: An integrated model combining a wildlife population simulation model, and timber harvest and growth models was developed to explore the tradeoffs between the likelihood of persistence of a wildlife species and timber harvest values on a landscape in the Central Oregon Cascades. Simulated annealing, a heuristic optimization technique, was used...

Identifying Opportunities for Collaboration in Resilience-Based Management: Coordinating Rancher and Land Manager Incentives

Creator:: Maher, Anna T.
Abstract:: Resilience-based management in rangelands implies maintaining desirable ecological states and avoiding thresholds to less desirable ones; however, the efficacy of resilience-based management depends upon several driving forces. These forces include management by those who depend upon rangelands for their livelihoods, the current state of ecological health of rangelands, and changing...

Integrated Spatio-temporal Sustainability Analysis of Biofuels Using Biogeochemistry, Economic and Life Cycle Analysis

Creator:: Tabatabaie, Seyed Mohammad Hossein
Abstract:: Fossil fuels have been the main source of energy for a long period but due to growing concerns over climate change, oil depletion and energy security, the development of renewable sources of energy such as biofuels have been flourishing over the past few decades. Despite the fact that biofuels are...

Biochemical conversion of lignocellulosic biomass to ethanol : experimental, enzymatic hydrolysis modeling, techno-economic and life cycle assessment studies

Creator:: Kumar, Deepak
Abstract:: Ethanol production from lignocellulosic feedstock has been under intense scrutiny as a transportation fuel due to its potential to address concerns of increasing energy consumption, limited fossil energy resources, climate changes due to greenhouse gas emissions from fossil fuels, and especially use of non-food biomaterials, which address the biggest limitation...

Optimizing spatial and temporal aspects of nature reserve design under economic and ecological objectives

Creator:: Nalle, Darek J.
Abstract:: Alteration of natural areas in attempts to support increasing human populations has been a crucial yet less publicized contributor to the fall of many of the world's greatest civilizations, since healthy ecosystems can help maintain stable societies and economies. Given this unhappy fact and the ancient relationship between people and...

Enhancing hydrogen production in microbial electrolysis cells through development of platinum-free cathode and improvement of reactor design

Creator:: Hu, Hongqiang
Abstract:: Microbial electrolysis provides a new approach for hydrogen generation from renewable biomass. At current stage, the most likely limiting factors for successful scale up of this technology are the large internal resistance and high fabrication cost. This dissertation presents an attempt to overcome these limitations by investigating novel microbial electrolysis...

Linkages between mangrove forests and coral reefs : quantifying disturbance effects and energy flow between systems

Creator:: Granek, Elise F.
Abstract:: Interface habitats are considered valuable natural systems, tightly linked to adjacent habitats through the flow of matter and energy. However, there is limited research on mechanisms of connectivity such as movement of organisms and particulate matter and ways in which anthropogenic disturbance to interface habitats may affect immediate and adjacent...

A steady-state model of ecological hierarchy

Creator:: Thompson, Grant Garrison
Abstract:: A generalized mathematical model of ecosystems is developed. The model begins with the general class of systems known as state-determined systems, in which the time-derivative of each state variable is a function of some subset of the set of all system state variables and .environmental parameters. A formal basis is...

Photobiological hydrogen production from the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in sol-gel processed silica

Creator:: Dickson, David J.
Abstract:: Photobiological hydrogen production from live cells of the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in silica gel was investigated. Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Under certain conditions, Synechocystis sp. PCC...
