Dr. Fanan Ujoh
Reservoirs are Man’s attempt towards water re-distribution from regions/seasons of abundance/surplus to regions/seasons of scarcity. This study focuses on socio-environmental impacts of the Lower Usuma dam in Abuja, on its four surrounding communities. Stratified random sampling technique was employed in the administration of a questionnaire to 200 respondents. Using descriptive statistics and the student t-test for the analysis, the study discovered that: (i) there has been no significant improvement in infrastructure provision by Government; (ii) cases of water-borne diseases are high; (iii) the communities have lost land for cultivation; and, (iv) the communities believe that the resettlement scheme is not …
An Evaluative Framework For Assessing Information Management In Watershed Management: The Case Of The Grand River Conservation Authority (Ontario), Robert Scott Brown
An Evaluative Framework For Assessing Information Management In Watershed Management: The Case Of The Grand River Conservation Authority (Ontario), Robert Scott Brown
Dr Robert Brown
Watershed management has been rapidly evolving over the last 50 years. The current focus has been adaptive and ecosystem-based approaches to watershed management, redefining roles, responsibilities, and relationships of watershed organizations. While entire management models need to be heavily scrutinized, the practices and policies surrounding information are fundamentally important. Information forms the understanding and knowledge for watershed decision-making. Watershed organizations need to be critical of the policies and practices affecting their collection, storage, processing, analysis, monitoring, and reporting of data and information. Among the Conservation Authorities, the GRCA has developed a proficiency at information management, doing it as well as …

Interactions Of Zooplankton And Phytoplankton With Cyanobacteria, Rebecca Alexander
Interactions Of Zooplankton And Phytoplankton With Cyanobacteria, Rebecca Alexander
School of Natural Resources: Dissertations, Theses, and Student Research
Cyanobacteria are a major concern in Nebraska reservoirs and are capable of producing toxins that can cause skin irritations and gastrointestinal problems, as well as affect the nervous system. It is important to determine the mechanisms that can cause cyanobacteria blooms due to the effect they can have on human health. The interaction of zooplankton and other phytoplankton groups with cyanobacteria is important because there is a biological component in surface waters that should be taken into consideration along with the physical and chemical parameters that have been noted to promote cyanobacteria. For example, zooplankton have the ability to alter …

Local Residents' Experience Of The Coal Ash Spill In Kingston, Tennessee: A Phenomenological Study, Amy Lynn Mathis
Local Residents' Experience Of The Coal Ash Spill In Kingston, Tennessee: A Phenomenological Study, Amy Lynn Mathis
Doctoral Dissertations
On December 22, 2008, near Kingston, Tennessee, a Tennessee Valley Authority (TVA) retention pond holding approximately 1.7 million cubic yards of coal fly ash failed, spilling the ash into the nearby Emory River and inundating farms and homes in the Swan Pond community. As a result more than 100 people were permanently displaced from their homes and the clean-up effort is ongoing.
The purpose of this study was to explore the experience of living near Kingston, Tennessee, in the aftermath of the spill. Using existential phenomenology as the guiding research methodology, I interviewed 9 participants from the area and asked …
Logistic Curves, Extraction Costs And Peak Oil, Robert J. Brecha
Logistic Curves, Extraction Costs And Peak Oil, Robert J. Brecha
Physics Faculty Publications
Debates about the possibility of a near-term maximum in world oil production have become increasingly prominent over the past decade, with the focus often being on the quantification of geologically available and technologically recoverable amounts of oil in the ground. Economically, the important parameter is not a physical limit to resources in the ground, but whether market price signals and costs of extraction will indicate the efficiency of extracting conventional or nonconventional resources as opposed to making substitutions over time for other fuels and technologies. We present a hybrid approach to the peak-oil question with two models in which the …
Ghost Tiger Beetle (Cicindela Lepida): Species Conservation Assessment, Melissa J. Panella
Ghost Tiger Beetle (Cicindela Lepida): Species Conservation Assessment, Melissa J. Panella
Nebraska Game and Parks Commission: Publications
The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the ghost tiger beetle, a.k.a. white tiger beetle, (Cicindela lepida) as a Tier I at-risk species of high conservation priority. Some general management recommendations are made here regarding ghost tiger beetles; however, conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge …

The Northern Great Plains Inventory & Monitoring Network (NGPN) surveyed 8 long-term monitoring plots in Scotts Bluff National Monument in 2012 as part of an effort to better understand the condition of plant communities in the park. We measured plant diversity and cover, estimated tree and shrub density, looked for the presence of exotic species that are of concern to park management, and evaluated the amount of human and natural disturbance at all plots. This effort was the second year in a multiple-year venture to document the current …
A Watershed Scale Evaluation Of Selected Second Generation Biofeedstocks On Water Quality, Gurdeep Singh
A Watershed Scale Evaluation Of Selected Second Generation Biofeedstocks On Water Quality, Gurdeep Singh
Graduate Theses and Dissertations
This study compares a novel simulation approach to the conventional Soil and Water Assessment Tool (SWAT) modeler's approach for targeting biofuel crop production on marginal lands. In conventional SWAT modeling approach, non-spatial definition of hydrological response units (HRUs) results in the simulation of biofuel crops on both marginal and non-marginal land. This study provides an alternative approach in which a marginal-land raster was integrated into the land use and land cover (LULC) raster in such a way that the land uses were divided into marginal and non-marginal components. This modified LULC was used for model setup which resulted in marginal …

In an effort to better understand the ancestral state of the human distal gut microbiome, we examine feces retrieved from archaeological contexts (coprolites). To accomplish this, we pyrosequenced the 16S rDNA V3 region from duplicate coprolite samples recovered from three archaeological sites, each representing a different depositional environment: Hinds Cave (~8000 years B.P.) in the southern United States, Caserones (1600 years B.P.) in northern Chile, and Rio Zape in northern Mexico (1400 years B.P.). Clustering algorithms grouped samples from the same site. Phyletic representation was more similar within sites than between them. A Bayesian approach to source-tracking was used to …

Effects Of Silvicultural Management On Coast Redwood Forest Composition, Density And Structure In Santa Cruz And San Mateo Counties, Michael J. Papa
Master's Theses
The multiple-objective exploratory study investigates effects of various silvicultural management regimes commonly applied to coast redwood (Sequoia sempervirens [D. Don] Endl.) forests in Santa Cruz and San Mateo Counties, California, USA. A temporary forest inventory was installed in 24 harvest origin stands and 4 natural origin stands throughout the study area (sample area = 1189 acres). Data from the systematic sample of 233 one-quarter acre nested cluster plots (sample intensity = 4.9%) rendered overall forest descriptions in terms of species composition, density, and structure. The common forestry measures of trees per acre (TPA), basal area per acre (BA), and …
Assessing The Impacts Of Surface Water Removal For Use In Natural Gas Extraction On A Watershed Level, Carrie Ann Davis
Assessing The Impacts Of Surface Water Removal For Use In Natural Gas Extraction On A Watershed Level, Carrie Ann Davis
Graduate Theses and Dissertations
In this study, the Soil and Water Assessment Test (SWAT) was used as a tool to predict whether diffuse water removal from the Cadron Creek watershed for use with natural gas development would have an impact on downstream flow within the watershed. Cadron Creek watershed expands across four counties within Arkansas and is located in the Fayetteville Shale Gas region. This region is experiencing significant growth in natural gas development. Successful development of shale gas depends on the identification of what water supplies are available for production without interfering with community and environmental needs. The SWAT model used to evaluate …
Public Land In A Changing Climate: Planning For An Uncertain Future, Kathleen Marie Hauser
Public Land In A Changing Climate: Planning For An Uncertain Future, Kathleen Marie Hauser
Masters Theses
This thesis investigates the ways in which institutions and actors consider climate change, and how the inclusion of diverse perspectives and challenges in the planning process shapes climate change governance. In particular, I asked how the participants, place-specific contexts, and decision-making processes affect environmental decision-making in Alaska’s National Parks. I discuss the literature on geographical perspectives on climate change, environmental and climate change governance, how uncertainty and risk affect decision-making in the context of climate change, and the history of land use management in the United States. This project incorporates qualitative methods to research the Climate Change Scenario Planning project …
