Urban Dwellers Experiences Regarding Loss Of Natural Environments Due To Rapid Urbanization, Erica Montanye 2017 Walden University

Urban Dwellers Experiences Regarding Loss Of Natural Environments Due To Rapid Urbanization, Erica Montanye

Walden Dissertations and Doctoral Studies

Little is known about how residents of rapidly growing cities are impacted by the loss of natural environments. Large cities are expanding at an exponential rate, reducing the presence of, and access to, natural environments for urban dwellers. Many benefits to human health regarding the presence of natural environments near where people live and work are known, but impacts of the loss of natural environments for urban dwellers are unknown. The purpose of this qualitative investigation was to understand residents' experiences regarding the loss of natural environments and related impacts. Attention restoration theory and place attachment were the theoretical lenses ...


Burundi : Water Scarcity, Isabel Salas 2017 Augustana College, Rock Island Illinois

Burundi : Water Scarcity, Isabel Salas

Global Public Health

Burundi is located near the African great lakes region of East Africa. This country is one of the poorest and hungriest countries throughout the world because of this they are facing multiple problems with communicable disease. These families are seeing a reduction in the amount of water available to them and based on this they are receiving water from external sources such as wells and lakes. Most of the water throughout Burundi is contaminated with Phytoplankton which increase cholera outbreaks in this area. It has also been shown that uranium impacts the water throughout the wells and lakes. Both of ...


Developing A Hydrological Monitoring Program For Ponds In Wapusk National Park, Manitoba, Using Water Isotope Tracers, Stephanie Roy 2017 Wilfrid Laurier University

Developing A Hydrological Monitoring Program For Ponds In Wapusk National Park, Manitoba, Using Water Isotope Tracers, Stephanie Roy

Theses and Dissertations (Comprehensive)

Northern lake-rich landscapes are vulnerable to increases in surface air temperatures and are changing in dynamic ways. Current meteorological records indicate that some of the greatest warming in the past century has occurred in the Hudson Bay Lowlands (HBL). As the HBL is an extensive wetland consisting of hundreds of thousands of shallow lakes and ponds, it is difficult to anticipate the long-term implications that climate change will have on pond water balance. To develop and implement long-term monitoring of hydrological conditions, sampling of pond water isotope composition has occurred during the past six years in Wapusk National Park (WNP ...


Malta : Natural Freshwater Resources, Lisamarie Pereira 2017 Augustana College, Rock Island Illinois

Malta : Natural Freshwater Resources, Lisamarie Pereira

Global Public Health

The aim of this paper is to discuss Malta’s struggle with limited natural freshwater resources. Malta currently uses aquifers to obtain natural freshwater. For over a decade, aquifers have been under pressure from over-abstraction. Due to this issue, Malta has not been able to obtain enough natural freshwater for agriculture and basic living. The biggest risk due to over-abstraction is retrieving a smaller volume of freshwater. In Malta’s attempted interventions, the biggest issue is the Maltese government’s misconceptions. The Maltese government believes the country has unlimited natural freshwater resources. Due to this misconception, nothing is being done ...


Chad : Hepatitis E, Hanna Pegarsch 2017 Augustana College, Rock Island Illinois

Chad : Hepatitis E, Hanna Pegarsch

Global Public Health

Contaminated drinking water in Chad is the main source for a Hepatitis E outbreak, leading Chad citizens to develop severe illness including jaundice, liver-failure, miscarriage, and death. There are 0.4 physicians for every 10,000 people living in Chad needing healthcare. Of the citizens in Chad, only 42% have access to uncontaminated drinking water. With such a long incubation period for Hepatitis E, the citizens don’t know they are spreading the illness to the rest of their community. Even with the symptoms, the citizens don’t have the access or the capacity for treatment, making Hepatitis E an ...


Social Justice In Social-Ecological Systems: Resilience Through Stakeholder Engagement, Frederick I. Lauer 2017 University of Montana, Missoula

Social Justice In Social-Ecological Systems: Resilience Through Stakeholder Engagement, Frederick I. Lauer

Graduate Student Theses, Dissertations, & Professional Papers

Successful management of social-ecological systems (SES) is predicated on quality collaborative exchanges between project stakeholders and management. The Southwest Crown of the Continent Collaborative (SWCC) Collaborative Forest Landscape Restoration Program (CFLRP) provided an opportunity to explore landscape scale collaborative management and SES outcomes. Global change and future uncertainty of landscapes prompted the SWCC to employ restoration treatment alternatives throughout 1.4 million acres of forests, most of which are publicly held. The SWCC currently monitors environmental and economic variables, with plans to monitor social variables. This thesis formalizes a proposed framework to investigate SES resilience, and explores public engagement as ...


Does Timing Of Herbicide Use Influence Rates Of Germination Or Seedling Biomass Of Native Plants Used For Restoration?, Christine McManamen 2017 University of Montana, Missoula

Does Timing Of Herbicide Use Influence Rates Of Germination Or Seedling Biomass Of Native Plants Used For Restoration?, Christine Mcmanamen

Graduate Student Theses, Dissertations, & Professional Papers

Invasive plants can negatively impact native grasslands by changing their species composition, productivity, and function. Managers commonly use herbicides as a control method; however, this practice can lead to secondary invasion by other non-native invasive plants, unless measures are taken to promote natives. Because of this, managers often seed native plants after spraying herbicides. There is evidence, however, that chemical control of invasive plants may reduce the effectiveness of subsequent seed-addition treatments, but there is currently little quantitative information on optimal timing between spraying and seeding or on variation in herbicide sensitivity among native plants commonly used in seed mixes ...


The Last Best Hope: Are Voluntary Conservation Agreements Effective Tools For Protecting Imperiled Species?, Sophie B. Tsairis 2017 University of Montana, Missoula

The Last Best Hope: Are Voluntary Conservation Agreements Effective Tools For Protecting Imperiled Species?, Sophie B. Tsairis

Graduate Student Theses, Dissertations, & Professional Papers

Candidate Conservation Agreements with Assurances, or CCAAs, are little known, voluntary conservation agreements that protect imperiled wildlife on private lands. These agreements have emerged over the past decade and have had mixed results in providing adequate protections for candidate species.

Landowners, private industries, state and federal agencies, and environmental nonprofits, are using CCAAs as tools to eliminate the need for an endangered species listing. An Endangered Species Act listing can lead to land-use uncertainty for private landowners and this threat is the main incentive to enroll in a CCAA. When landowners enroll in CCAAs they are agreeing to provide specific ...


Understanding Community Character As A Socio-Ecological Framework To Enhance Local-Scale Adaptation: An Interdisciplinary Case Study From Rural Northwest Connecticut, Joanna Wozniak-Brown 2017 Antioch University, New England

Understanding Community Character As A Socio-Ecological Framework To Enhance Local-Scale Adaptation: An Interdisciplinary Case Study From Rural Northwest Connecticut, Joanna Wozniak-Brown

Dissertations & Theses

Around the world, municipalities are facing new challenges, not the least of which is climate change. This is especially true for rural communities that, for a variety of reasons, will be disproportionately affected by the climatic changes and accompanying policies or programs.

This dissertation, written in manuscript-style, integrates climate change and social-ecological scholarship to address the unique character of rural communities, to communicate the complexity of rural identity through the term "rural character"; and to empower rural communities to incorporate adaptation strategies into their daily municipal operations and planning.

Specifically, this dissertation seeks to answer the following questions: What is ...


Speciation, Distribution, Prediction, And Mobility Of Lead In Urban Soils: A Multiscale Study, Jennifer Bower 2017 University of Vermont

Speciation, Distribution, Prediction, And Mobility Of Lead In Urban Soils: A Multiscale Study, Jennifer Bower

Graduate College Dissertations and Theses

Lead (Pb), a trace metal notorious for its impacts on human health, has achieved worldwide environmental dispersal resulting from centuries of use by human society. The toxicity of Pb is governed largely by its mineral form, which is in turn controlled by pH, localized reactivity and soil processes that differ according to soil type, location and Pb source. Given the context of these localized dependencies, or site specificity, efforts to predict Pb toxicity and refine sustainable remediation techniques are most useful when Pb behavior is constrained and predicted within environments with homogeneous conditions, such as a single soil. I evaluated ...

Weight Of Evidence Evaluation Of A Network Of Adverse Outcome Pathways Linking Activation Of The Nicotinic Acetylcholine Receptor In Honey Bees To Colony Death, Carlie A. Lalone, Daniel L. Villeneuve, Judy Wu-Smart, Rebecca Y. Milsk, Keith Sappington, Kristina V. Garber, Justin Housenger, Gerald T. Ankley

U.S. Environmental Protection Agency Papers

Ongoing honey bee (Apis mellifera) colony losses are of significant international concern because of the essential role these insects play in pollinating crops. Both chemical and non-chemical stressors have been implicated as possible contributors to colony failure; however, the potential role(s) of commonly-used neonicotinoid insecticides has emerged as particularly concerning. Neonicotinoids act on the nicotinic acetylcholine receptors (nAChRs) in the central nervous system to eliminate pest insects. However, mounting evidence indicates that neonicotinoids also may adversely affect beneficial pollinators, such as the honey bee, via impairments on learning and memory, and ultimately foraging success. The specificmechanisms linking activation of ...


Groundwater-Surface Water Connectivity And Carbon Dynamics In A Coal Seam Gas Exploration Area, Marnie Louise Atkins 2017 Southern Cross University

Groundwater-Surface Water Connectivity And Carbon Dynamics In A Coal Seam Gas Exploration Area, Marnie Louise Atkins

Theses

This thesis provides a comprehensive regional baseline analysis of groundwater and surface water characteristics in the subtropical Richmond River Catchment (Australia) with the main focus on methane (the dominant gas in coal seam gas, CSG) and radon (a natural groundwater tracer). The study site is an area of high interest due to planned CSG development. Overall results demonstrate broad catchment scale spatial and temporal variability in groundwater and surface water dynamics. The results serve as a regional baseline assessment of groundwater-surface water connectivity and chemistry prior to the development of CSG fields.


Iron, Sulfur And Trace Metals Geochemistry During Redox Oscillations In Freshwater Re-Flooded Acid Sulfate Soil Wetlands, Niloofar Karimian 2017 Southern Cross University

Iron, Sulfur And Trace Metals Geochemistry During Redox Oscillations In Freshwater Re-Flooded Acid Sulfate Soil Wetlands, Niloofar Karimian

Theses

This thesis examined three important aspects of Fe and S biogeochemistry in freshwater re-flooded ASS wetlands with cyclic redox oscillations, (i) the stability of RIS and Fe species (ii) short- and long-term changes in Fe and S speciation and trace metals behaviour during drought and (iii) transformation of jarosite and subsequent behaviours of As and Sb, in these wetlands. The findings suggest a 2-3 weeks drought, can lead to the quick release of H+ with a potential for rapid pH recovery following re-flooding. This research also suggests lepidocrocite, GR-SO4 and goethite can scavenge As(V)/ Sb(V) under Fe2 ...

Terrestrial Versus Aquatic Carbon Fluxes In An Agricultural Coastal Floodplain, Jackie Roslyn Webb 2017 Southern Cross University

Terrestrial Versus Aquatic Carbon Fluxes In An Agricultural Coastal Floodplain, Jackie Roslyn Webb

Theses

In ecosystems at the terrestrial-aquatic interface, the carbon cycle is intricately connected between these two components. However, these terrestrial-aquatic carbon subsidies are often neglected in carbon budgets. This dissertation addresses the role of the aquatic pathway in the carbon budget of a “model” ecosystem representing a well constrained catchment. By combining terrestrial and aquatic methodologies, the study revealed important findings on the drivers of aquatic carbon fluxes and the relative contribution of this pathway to offsetting the land carbon sink. This study demonstrated that an interdisciplinary approach to terrestrial-aquatic ecosystems propels our understanding of carbon cycling in these systems.


Antibiotics And Antibiotic-Resistant Bacteria In Coastal Plain Streams, Jason Duff 2017 Georgia Southern University

Antibiotics And Antibiotic-Resistant Bacteria In Coastal Plain Streams, Jason Duff

Electronic Theses & Dissertations

Streams across the United States and globally are influenced by environmental contamination, including antibiotics, which enter streams due to widespread use and multiple pathways into the environment. Antibiotics are also likely to enter streams in mixture with other contaminants that alter the effects on aquatic organisms. Furthermore, antibiotic-resistant bacteria enter streams through similar pathways as antibiotics with implications for natural microbial communities. Therefore, understanding the presence and effects of antibiotic-contaminant mixtures and antibiotic-resistant bacteria in streams is important for resource management.

Chapter one describes an experiment that tested the hypothesis that the antibiotic tetracycline (TC) alone influences phytoplankton communities differently ...
