A Comparison Of Two Common Classification Procedures For Economical Urban Land Cover Mapping Using Naip Imagery, Kent Lowell Simons

Theses and Dissertations

Detailed urban land cover maps are increasingly useful and important applications of remote sensing. Municipal agencies and others use land cover maps and data for numerous critical local planning and monitoring functions and for urban geographical research studies. Because of this, there is a demand for accurate urban land cover maps that can be produced quickly and economically. The availability of very high resolution multispectral imagery is an important factor in enabling such production, as the judicious selection of source imagery has a large impact on the resulting map products. Likewise, the implementation of appropriate digital image processing methods is …

An Undescribed Gecko (Gekkonidae: Cyrtodactylus) From Deer Cave, Gunung Mulu National Park, Sarawak, With Comments On The Distribution Of Bornean Cave Geckos, Donald A. Mcfarlane, Joyce Lundberg, Keith Christenson

WM Keck Science Faculty Papers

Geckos of the genus Cyrtodactylus are a speciose group in Southeast Asia, with at least nine species known from the island of Borneo (Das & Ismail, 2001; Das, 2006). Of these species, Cyrtodactylus cavernicolus has the smallest known range and is therefore the most vulnerable, a status that is reflected in the species having been designated a Totally Protected Species in Sarawak. Confirmed records of C. cavernicolus are known only from Niah Cave, located in an isolated limestone block known as the Gunung Subis massif, approximately 13 km² in extent. The Niah Cave Gecko is presumed to be dependent on …

The Role Of Landscape Connectivity In Assembling Exotic Plant Communities: A Network Analysis, Emily S. Minor, Samantha M. Tessel, Katharina A.M. Engelhardt, Todd R. Lookingbill

Geography and the Environment Faculty Publications

Landscape fragmentation and exotic species invasions are two modern-day forces that have strong and largely irreversible effects on native diversity worldwide. The spatial arrangement of habitat fragments is critical in affecting movement of individuals through a landscape, but little is known about how invasive species respond to landscape configuration relative to native species. This information is crucial for managing the global threat of invasive species spread. Using network analysis and partial Mantel tests to control for covarying environmental conditions, we show that forest plant communities in a fragmented landscape have spatial structure that is best captured by a network representation …

Bats And Bell Holes: The Microclimatic Impact Of Bat Roosting, Using A Case Study From Runaway Bay Caves, Jamaica, Joyce Lundberg, Donald A. Mcfarlane

WM Keck Science Faculty Papers

The microclimatic effect of bats roosting in bell holes (blind vertical cylindrical cavities in cave roofs) in Runaway Bay Caves, Jamaica, was measured and the potential impact of their metabolism on dissolution modelled. Rock temperature measurements showed that bell holes with bats get significantly hotter than those without bats during bat roosting periods (by an average of 1.1 °C). The relationship is clearest for bell holes with more than about 300 g aggregate bat body mass and for bell holes that are moderately wide and deep, of W:D ratio between 0.8 and 1.6. Measurement of temperature decay after abandonment showed …

The Tadpole Of Hypsiboas Atlanticus (Anura, Hylidae) From Northeastern Brazil, Filipe A. C. Do Nascimento, Marcelo G. De Lima, Gabriel O. Skuk, Rafael O. De Sá

Biology Faculty Publications

The tadpole of Hypsiboas atlanticus (Caramaschi & Velosa, 1996) is described from the municipality of Maceió, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1). The oral disc is surrounded, almost completely (anterior medial gap present) by a single row of marginal papillae. Described tadpoles of the H. punctatus species group can be differentiated by a combined disc oral features. Additional descriptions of H. punctatus (Schneider, 1799) tadpoles from populations throughout South America may be helpful in determining …

Responding To Change In A Northern Aboriginal Community (Fort Resolution, Nwt, Canada): Linking Social And Ecological Perspectives, Sonia Darienne Wesche

Theses and Dissertations (Comprehensive)

Human and environmental systems in the circumpolar north are particularly affected by the Earth’s changing climate, thus acting as a bellwether for other parts of the globe. Rural indigenous communities are most visibly impacted due to their close relationship with the land. These challenges are compounded by socio-economic transformations typical of peripheral communities within a larger, centrally governed system.

This dissertation links a community-based study of environmental change in Fort Resolution, Northwest Territories, Canada to evolving adaptation science. The study was prompted by local concern about changing environmental conditions caused by climatic, hydrological and resource development drivers. Its collaborative research …

The Role Of Geospatial Thinking And Geographic Skills In Effective Problem Solving With Gis: K-16 Education, Niem Tu Huynh

Theses and Dissertations (Comprehensive)

Effective use of a Geographic Information System (GIS) is hampered by the limited geospatial reasoning abilities of students. The ability to reason with spatial relations, more specifically apply geospatial concepts, including the identification of spatial patterns and spatial associations, is important to geographic problem solving in a GIS context. This dissertation examines the broad influence of three factors on GIS problem solving: 1) affection towards computers, geography, and mathematics, 2) geospatial thinking, as well as 3) geographic skills.

The research was conducted with 104 students in Waterloo, Ontario, Canada. Students were drawn from four educational levels: grade 9 students, 13 …

Cookie Monsters: Seeing Young People’S Hacking As Creative Practice, Gregory T. Donovan, Cindi Katz

Publications and Research

This paper examines the benefits and obstacles to young people’s open-ended and unrestricted access to technological environments. While children and youth are frequently seen as threatened or threatening in this realm, their playful engagements suggest that they are self-possessed social actors, able to negotiate most of its challenges effectively. Whether it is proprietary software, the business practices of some technology providers, or the separation of play, work, and learning in most classrooms, the spatial-temporality of young people’s access to and use of technology is often configured to restrict their freedom of choice and behavior. We focus on these issues through …

Proving Grounds Of Urbicide: Civil And Urban Perspectives On The Bombing Of Capital Cities, Kenneth Hewitt

Geography and Environmental Studies Faculty Publications

In the bombing of urban settlements, the main impacts have been on resident civilians, living space and non-military functions. This is shown in the bombing of London, Berlin and Tokyo in the Second World War, arguably the first and only serious tests of strategic air power and urbicide to determine war outcomes. The history and scope of raiding of these capital cities differed in many ways, but the civilian experience and urban implications were very similar. The bombings attacked the most vulnerable areas, where resident populations found themselves poorly protected at best. The intentions, as well as results, of the …

Surface Mining And Reclamation Effects On Flood Response Of Watersheds In The Central Appalachian Plateau Region, Todd R. Lookingbill, Joseph R. Ferrari, B. Mccormick, P. A. Townsend, K. N. Eshleman

Geography and the Environment Faculty Publications

Surface mining of coal and subsequent reclamation represent the dominant land use change in the central Appalachian Plateau (CAP) region of the United States. Hydrologic impacts of surface mining have been studied at the plot scale, but effects at broader scales have not been explored adequately. Broad-scale classification of reclaimed sites is difficult because standing vegetation makes them nearly indistinguishable from alternate land uses. We used a land cover data set that accurately maps surface mines for a 187-km2 watershed within the CAP. These land cover data, as well as plot-level data from within the watershed, are used with HSPF …

Altered Ecological Flows Blur Boundaries In Urbanizing Watersheds, Todd R. Lookingbill, Sujay S. Kaushal, Andrew J. Elmore, Robert Gardner, Keith N. Eshleman, Robert H. Hilderbrand, Raymond P. Morgan, Walter R. Boynton, Margaret A. Palmer, William C. Dennison

Geography and the Environment Faculty Publications

The relevance of the boundary concept to ecological processes has been recently questioned. Humans in the post-industrial era have created novel lateral transport fluxes that have not been sufficiently considered in watershed studies. We describe patterns of land-use change within the Potomac River basin and demonstrate how these changes have blurred traditional ecosystem boundaries by increasing the movement of people, materials, and energy into and within the basin. We argue that this expansion of ecological commerce requires new science, monitoring, and management strategies focused on large rivers and suggest that traditional geopolitical and economic boundaries for environmental decision making be …

Flame, Furnace, Fuel: Creating Kansas City In The Nineteenth Century, Twyla Dell

Antioch University Dissertations & Theses

Though this work is a fuel and energy history of Kansas City from 1820 to 1920, it also provides a tool to describe and analyze fuel and energy transitions. The four parts follow the rise and fall of wood, coal and oil as their use grows to a peak and, in the case of wood, declines. The founding and growth of Kansas City as an “instant city” that grew from zero population to over three hundred twenty thousand in a hundred years embodies the increased use of fuels and energy in an urban setting and serves as a case study. …

Geography And Capacity Of Alternative Fuel Production 1999 - 2006: The Case Of Solar And Wind, James Pace

All-Inclusive List of Electronic Theses and Dissertations

Access to reliable, low cost energy production is key to the wellbeing of our economy, standard ofliving, and national security. As the cost of energy from conventional resources has increased, efforts have started to convert to alternative, renewable sources of energy production. Currently, wind and solar technologies are the best options for an alternative source of energy. Data on wind and solar energy resources, the availability of incentives, and the existence of renewable portfolio standards (RPS) were used to determine the most plausible influencing factors of wind and solar energy production. Maps generated from these data point to a relationship …

Finding A "Disappearing" Nontimber Forest Resource: Using Grounded Visualization To Explore Urbanization Impacts On Sweetgrass Basketmaking In Greater Mt. Pleasant, South Carolina, Patrick T. Hurley, Angela C. Halfacre, Norm S. Levine, Marianne K. Burke

Environment and Sustainability Faculty Publications

Despite growing interest in urbanization and its social and ecological impacts on formerly rural areas, empirical research remains limited. Extant studies largely focus either on issues of social exclusion and enclosure or ecological change. This article uses the case of sweetgrass basketmaking in Mt. Pleasant, South Carolina, to explore the implications of urbanization, including gentrification, for the distribution and accessibility of sweetgrass, an economically important nontimber forest product (NTFP) for historically African American communities, in this rapidly growing area. We explore the usefulness of grounded visualization for research efforts that are examining the existence of "fringe ecologies" associated with NTFP. …

Geoarchaeological And Paleolandscape Reconstructions In The Lower Ohio River Valley: Late Wisconsin And Early Holocene Landforms In Knob Creek Bottom, Nathan Christopher Scholl

All-Inclusive List of Electronic Theses and Dissertations

This study examines a paleolandscape model that focuses on alluvial landforms that date to the Late Pleistocene and Early Holocene in Knob Creek bottom of the lower Ohio River valley. The study tests and refines a landscape model based on geoarchaeological data from the Caesars Archaeological Project. Analysis centers on the relationship between late Wisconsin and early Holocene Landform Sediment Assemblages (LSA), including early paleochannels. For this analysis a series of soil cores was extracted from the LSA understudy and described using standard USDA terminology. Additional analysis included particle size analysis using a hydrometer to determine textural composition of core …

Analysis Of Spatial Distribution Of Hazardous Wastes In Semcog Region, Michigan, Junfang Chen

Masters Theses

This research is devoted to an increasingly recognized issue: environmental injustice, that is, the distribution of environmental risks and/ hazards are disproportionably distributed in the space in terms of the effects on the victims. Specifically, this thesis focuses on an analysis of the spatial distribution of hazardous materials from fixed incidents and the characteristics of neighborhoods living near the incident sites, so as to test the hypothesized relationships that poor people and minority people live near the incident sites. SEMCOG region, Michigan is chosen as the study area due to its frequent occurrence of incidents involving environmental hazards. It is …

Darfur: Rainfall And Conflict, Michael Kevane, Leslie C. Gray

Economics

Data on rainfall patterns only weakly corroborate the claim that climate change explains the Darfur conflict that began in 2003 and has claimed more than 200,000 lives and displaced more than two million persons. Rainfall in Darfur did not decline significantly in the years prior to the eruption of major conflict in 2003; rainfall exhibited a flat trend in the thirty-years preceding the conflict (1972-2002). The rainfall evidence suggests instead a break around 1971. Rainfall is basically stationary over the pre- and post-1971 sub-periods. The break is larger for the more northerly rainfall stations, and is less noticeable for En …

Habitat Selection By A Rare Forest Antelope: A Multi-Scale Approach Combining Field Data And Imagery From Three Sensors, Lyndon Estes, G. S. Okin, A. G. Mwangi, H. H. Shugart

Geography

It can be difficult to further scientific understanding of rare or endangered species that live in inaccessible habitat using traditional methods, such as probabilistic modeling based on field data collection. Remote sensing (RS) can be an important source of information for the study of these animals. A key advantage of RS is its ability to provide information over an animal's complete range, but models incorporating RS data are limited by RS's ability to detect important habitat features. In this study, we focus on the rare, poorly-understood mountain bongo antelope (Tragelaphus euryceros isaaci) which survives in the wild in isolated pockets …

Hazard Adaptations Along The Ohio River: A Case Study Of Bushman's Lake, Clark County, Indiana, Jennifer L. Lathem

All-Inclusive List of Electronic Theses and Dissertations

Hazard researchers define a hazard as a threat to people and their belongings (Cutter 2001). An adaptation, for the purposes of this research, is any alteration, physical or behavioral, made by a person in which the person is better able to survive in their "hazardous" natural environment. The challenge facing individuals and communities is the ability to adapt to these hazards so as to continue with normal everyday life. People living near a waterway are faced with flooding, which becomes a hazard when it alters everyday social structures. The purpose of this study is to identify flood hazard adaptations in …

Geography, Poverty, And Development Policy In The New African Millennium: Monitoring The Millennium Development Goals Through Human Development, Joseph Tamba Koroma

All-Inclusive List of Electronic Theses and Dissertations

The eight United Nations Millennium Development Goals (MDGs) are to eradicate extreme poverty and hunger, achieve universal primary education, promote gender equality and empower women, reduce child mortality, improve maternal health, combat HIV I AIDS, ensure environmental sustainability, and develop a global partnership for development. The eighth goal (MDG 8), aims to develop and strengthen a global partnership for development between rich and poor countries. Three main components of the latter (MDG 8) aim to accelerate the infusion of official development aid (ODA), liberalize international trade, and introduce information and communication technologies (ICT) in the hope of creating a conducive …

Human–Wildlife Conflict And Gender In Protected Area Borderlands: A Case Study Of Costs, Perceptions, And Vulnerabilities From Uttarakhand (Uttaranchal), India, Monica V. Ogra

Environmental Studies Faculty Publications

Human–wildlife conflict (HWC) is a growing problem for communities located at the borders of protected areas. Such conflicts commonly take place as crop-raiding events and as attack by wild animals, among other forms. This paper uses a feminist political ecology approach to examine these two problems in an agricultural village located at the border of Rajaji National Park in Uttarakhand (formerly Uttaranchal), India. Specifically, it investigates the following three questions: What are the “visible” and “hidden” costs of such conflict with wildlife? To what extent are these costs differentially borne by men and women? How do villagers perceive any such …

Introduction: Cotton, Globalization, And Poverty In Africa, William G. Moseley, Leslie C. Gray

Environmental Studies and Sciences

This volume employs a modified commodity chain approach, focusing on the social, economic, and environmental dimensions of cotton production in Africa, and the links between this production and the global market. Individual chapters may examine one or multiple levels in the commodity chain and employ different theoretical approaches, from ethnography, to agroecology, to political ecology, to classic economic analysis. We want to acknowledge, however, that while the commodity chain is an important part of cotton dynamics, it is not the only force at work in African cotton. There are new and interesting developments outside the commodity chain that work for …

Cotton Production In Burkina Faso: International Rhetoric Versus Local Realities, Leslie C. Gray

Environmental Studies and Sciences

Voices ranging from the editorial page of the New York Times to organizations such as Oxfam and the presidents of Burkina Faso and Mali have argued that U.S. cotton subsidies depress world cotton prices and hurt African farmers. These policies deny West African countries their comparative advantage in cotton, which they can produce more cheaply and with lower environmental impacts than farmers in the United States. Some have gone as far as phrasing this as a national security issue; editorials in the New York Times and the Wall Street Journal have suggested that removing subsidies would have a strong auxiliary …

Conclusion: Hanging By A Thread: The Future Of Cotton In Africa, Leslie C. Gray, William G. Moseley

Environmental Studies and Sciences

Several broad themes emerge from the chapters in this volume. While declining world prices are a serious issue, the ability of farmers to weather declines in prices is often determined by national and local issues. These include government policy, institutions that provide marketing and supply services, access to resources such as land, labor, and agricultural inputs, and individual decision making. Despite declining world prices, some cotton growing economies have had success with cotton production while others have not fared well. In particular, the failure of cotton institutions in many countries is striking.Whether it comes to managing input distribution, new technologies, …

How The Formal Education System In Kenya Is Changing The Culture Of The Maasai Community, Jennifer Coles

Theses and Dissertations (Comprehensive)

Colonialism brough Africa into the sphere of European dominance and laid the ground work for the adoption of neoliberal globalization. This has affected change for the Maasai of southern Kenya who had attempted to remain isolated for much of the 19th and 20th centuries. However, such cultural isolation has been disrupted by global tourism and the desire of western citizens to view and participate in ‘authentic’ experiences in unique Maasai environments; thus creating a global desire to visit the Maasai Mara National Reserve (MMNR). The MMNR is part of Maasailand and has exposed many in the surrounding communities to new …

Paleohydrologic Reconstruction Of Three Shallow Basins, Slave River Delta, Nwt, Using Stable Isotope Methods, Cherie Mongeon

Theses and Dissertations (Comprehensive)

p>The long-term natural hydrological variability of the Slave River Delta (SRD), NWT, is not well documented and needs to be further developed to provide temporal context to understand and evaluate impacts of Slave River (SR) floodwater influence and climate variability and change on contemporary hydro-ecological doncidiotns of the SRD. The SRD has broad ecological and cultural significance, as it provides extensive habitate for wildlife and is important for local First Nations community who have an historical connection with the delta and its resources. Concners have been raised over recently reported drying trends in the SRD over the past few …

Reconstruction Of Peace River Flood Frequency And Magnitude For The Past ∼600 Years From Oxbow Lake Sediments, Peace-Athabasca Delta, Canada, Suzanne Jarvis

Theses and Dissertations (Comprehensive)

Ice-jam flooding in the Peace-Athabasca Delta (PAD) is an important hydrological process for the replenishment of shallow perched basins that support a highly productive northern ecosystem. The PAD is also used by nearby First Nations communities for traditional lifestyle occupations such as hunting and trapping. Previous research on laminated sediments collected from two oxbow lakes periodically connected to major Peace River distributaries has resulted in a 300-year record of flood frequency. In an effort to extend this record and broaden the understanding of the relationships among climate variability, Peace River hydrology, and delta hydroecology, a series of vibracores and gravity …
