What Drives Commercial Poaching?: From Poverty To Economic Inequality, Elizabeth Lunstrum, Nícia Givá

Global Studies Faculty Publications and Presentations

Over the last decade, South Africa and its iconic Kruger National Park have experienced a steep increase in the killing of rhinoceros for its horn, which is reaching staggering prices largely in Asian markets. This is a key piece of the larger illegal wildlife trade (IWT). Drawing on fieldwork in the Mozambican borderlands adjacent to Kruger where many poaching recruits originate, we respond to calls for better understanding of the drivers of IWT and in particular links between poverty and poaching. Our analysis shows that economic factors including poverty are the most central drivers of rhino poaching on the ground-level …

The Invasion Of The Southern Pine Bark Beetle, Matthew Shaughnessy

Transformations: Presentation Slides

The Southern Pine Bark Beetle is a pest that is native to the south eastern United States. Historically the population has been held to southern parts of the nation due to the harsher cold weather in the north. During the last twenty years there has been an increase in average annual temperatures on the east coast. This has allowed the species to move northward and afflict unprotected softwoods at a high rate. The objective of this project was to observe the movement of the Southern Pine Bark Beetles between 2012 and a population estimate for 2027 made by the USDA …

Changing Agricultural Landscapes: An Investigation Of Dragon Fruit Production In Southern Vietnam., Laura Krauser

Agricultural transition represents an essential component of land-use and land-cover change in developing countries across the world, as economic and social factors pressure agriculturalists out of traditional subsistence farming into food commodity production. Modernization has altered modes of income, land ownership, and livelihood in Southeast Asia drastically in recent years. The Bình Thuận Province of southern Vietnam experienced a particularly radical transformation with the introduction of dragon fruit cultivation, which has been profoundly encouraged by outside markets in China, Australia, and Japan. This research combines remote sensing and qualitative research to examine and characterize a changing agricultural landscape in rural …

Spatial Analysis Of Soil Creep Rates On Mount Sequoyah, Fayetteville Arkansas, Amy Suzanne Morris

Graduate Theses and Dissertations

Mount Sequoyah in Fayetteville, Arkansas, is a part of the Boston Mountains, which are considered a deeply dissected plateau. The area is prone to mass wasting, which is the general downslope movement of sediments, soils, and rock through different processes that cause instabilities along a hillslope, and in its soil and loose rubble mantle. For this study, we looked at soil creep, which is the small-scale movement of soil downhill because of gravity, wetting and drying cycles, and heating and cooling cycles.

By measuring the tilt of utility poles, we determined multiple causes of soil creep. The variables that are …

Characterizing The Impacts Of The Invasive Hemlock Woolly Adelgid On The Forest Structure Of New England, Peter Brehm Boucher

Graduate Doctoral Dissertations

Climate change is raising winter temperatures in the Northeastern United States, both expanding the range of an invasive pest, the hemlock woolly adelgid (HWA; Adelges tsugae), and threatening the survival of its host species, eastern hemlock (Tsuga canadensis). As a foundation species, hemlock trees underlie a distinct network of ecological, biogeochemical, and structural systems that will likely disappear as the HWA infestation spreads northward. Remote sensing can offer new perspectives on this regional transition, recording the progressive loss of an ecological foundation species and the transition of evergreen hemlock forest to mixed deciduous forest over the course of the infestation. …

Spatiotemporal Analysis Of Traffic Crashes Involving Pedestrians And Cyclists In Jefferson County, Kentucky., Joseph M. Garcia

College of Arts & Sciences Senior Theses

Walking and cycling are health-conscious, environmentally friendly modes of transportation, yet very few American trips are accomplished using these methods. A major factor behind this is the fear of being involved in a crash with an automobile. From 2009-2019 there were over 5,200 automobile crashes involving either pedestrians or cyclists in Louisville/ Jefferson County, Kentucky. Researchers have found that these kinds of crashes exhibit spatiotemporal patterns in different cities across the globe. The objective of this study was to determine if there exist any spatial and/or temporal patterns regarding these kinds of crashes. Data for this study came from the …

Geographic Imaginaries Of Urban Spatial Segregation: A Case Study Of The West End Neighborhoods In Louisville, Kentucky., Amber Dock

Electronic Theses and Dissertations

The objective of this thesis is to translate the framework of geographic imaginaries into an urban context in order to capture a narrative of how residents conceptualize and experience segregation. This framework is rooted in an investigation of local discourses as they exist within a specific social, political, and historical context. Institutionalized segregation and structural racism are the foundations on which the American urban context studied here was built upon. This study employs multiple methods, including contextualizing the study area, analyzing discursive content, and visualizing the results. The results of these analyses included empirically connecting concentrations of protected classes to …

Learning To Love Bats, Bethany J. Lawson

Honors Theses

Throughout history, bats have often become entangled in various myths and legends that have negatively influenced human perceptions of bats. Media outlets often sensationalize the relationship of bats to novel diseases, which also creates negative perceptions of bats in the human imagination. Bats are beneficial to our ecosystems and provide pollination services, seed dispersal, and insect control. However, bats are currently facing a variety of life-threatening issues, such as habitat destruction, fatalities at wind energy sites, climate change, and most notably, white-nose syndrome – a disease that has killed millions of North American bats in the past decade. With bats …

A Tale Of Two Species: Black-Tailed And White-Tailed Prairie Dog Biogeography From The Last Interglacial To 2070, April Dawn Bledsoe

Electronic Theses and Dissertations

Ecological niche models (ENMs) were created for White-tailed and Black-tailed prairie dogs and projected into the Last Interglacial (LI), the Last Glacial Maximum (LGM), and mid-Holocene (mid-H) to discern possible past suitable habitat for both species. Additionally, ENMs were projected into the future year 2070 representative concentration pathways (RCPs) 2.6 and 8.5 to discern how climate change may affect future habitat suitability. Kernel density estimations, minimum convex polygons, and median distribution centers of White-tailed and Black-tailed occurrence records were examined between time-periods to discern the effects of anthropogenic westward expansion on both species’ distributions. Current ENMs were constructed from commonly …

Landscapes Of Danger: A Geospatial Analysis Of Perceived And Realistic Risk In Bryce Canyon National Park, Tia Francis

Graduate Theses and Dissertations

The quantification of risk has inspired a wide breath of literature from the physical sciences, social sciences, and interdisciplinary disciplines like geography. Many attempts to estimate risk via natural hazards either focus on quantifying realistic risk or perceived risk of lay persons, with very little overlap between these paradigms. Due to this, a considerable knowledge gap exists within perceived risk and natural hazards research. This study aims to provide a comprehensive, risk estimation and assessment strategy through a multi-hazard risk assessment of Bryce Canyon National Park (BRCA). This case study analyzed knowledge of risk among visitors with perception surveys and …

An Evaluation Of Unmanned Aircraft Systems' Ability To Assess Stripe Rust In Large Wheat Breeding Nursies, Jamison T. Murry

Graduate Theses and Dissertations

Stripe Rust (Puccinia striiformis f. sp. tritici) is a foliar disease that significantly impacts global wheat production, and resistant cultivars provide the most efficient method of control. High-throughput phenotyping using unmanned aircraft systems (UAS) offers a potentially more efficient method for field-based phenotyping compared to visual assessment. Here we tested the ability of remote sensing to predict stripe rust severity in a diverse population of 594 soft red winter wheat lines, planted in single-rows, and evaluated them by visually rating stripe rust intensity and remotely using the dark green color index (DGCI), normalized difference vegetation index (NDVI) and blue NDVI. …

Gwaabaw: Applying Anishinaabe Harvesting Protocols To Energy Governance, Sakihitowin Awasis

Geography & Environment Publications

Oil and gas extraction has transformed Anishinaabe society in ways that undermine the consensual, holistic, and egalitarian basis of natural law. To many Indigenous people, framing fossil fuels and other energy sources as “natural resources” does not accurately define energy projects or capture related risks. Some Anishinaabe pipeline opponents have suggested that traditional harvesting protocols–culturally embedded moral precepts that govern the gathering of food and medicinal plants–also be applied to activities that produce energy. This paper explores how this could be done, focusing on tar sands extraction and the Line 3 expansion plan. I begin by discussing Anishinaabe harvesting protocols, …

Memorialization On College Campuses Today, Virginia Thornton

Geography and the Environment Capstone Projects

This study uses the theoretical basis of placemaking and memorialization to examine the placement of memorial landscapes on college campuses. The research is based in case study analysis of other college campuses. It looks specifically at where and what is memorialized and what elements of placemaking are incorporated. The main postulate of my research is that the location of the memorialization of the suspected slave burial ground and history of slave labor on Richmond’s campus is appropriately placed in the Eco-corridor. The research suggests this postulate is not true, as the majority of other memorials have been placed in more …

Systems Of Meaning In Place Attachment, Emily Routman

Geography and the Environment Capstone Projects

Numerous scholars agree that contact with natural landscapes has benefits for the landscape and the person experiencing them, including increased environmentally-responsible behaviors as well as psychological, cognitive, physiological, and social benefits. People develop a sense of place in outdoor landscapes while experiencing the physical environment, and sense of place is strengthened by place attachment – one’s emotional ties to a place. According to Williams and Patterson (1999), place attachment is perceived through four systems of meaning: 1) aesthetic/inherent, 2) goal-directed/instrumental, 3) cultural/symbolic, and 4) individual/expressive. The present study sought to understand which of these four systems of meaning are the …

How Do Farmers Experience Agroecology In Rural Communities Of Northern Ecuador?, Neil Michael Ayala Ayala

Latin American Studies ETDs

Agroecology, a concept in continuous evolution embraces science, practice and sociopolitical aspects. Its meaning is gaining space of debate and global interest as an alternative for building sustainable food systems and resilient communities, not only from the environmental perspective, but from all the dimensions of sustainability. The Andes region is recognized for its agrodiversity and for its history of agricultural activity; nevertheless, the effects of unsustainable agricultural practices inspired in the principles of the so called “Green Revolution” are evident. Conventional agriculture has decreased the capacity of resilience of the agroecosystems and their associated communities. Agroecology is often perceived as …

280— Exploring The Geographic Distribution Of Childbed Fever Deaths In Mid-19th Century Rochester, Ny, Meaghan Parks

GREAT Day Posters

Childbed fever, formally called puerperal fever or puerperal septicemia, is an infection typically contracted by women after childbirth. Historically, childbed fever was a serious threat to maternal health. Childbed fever is caused by exposure of open wounds or abrasions, which are common after giving birth, to group A and B Streptococcal bacteria. Ignaz Semmelweis discovered that hand washing using a chlorinated solution reduced cases of childbed fever in 1847. This project reviews the instances of death from childbed fever in Rochester, New York from 1837-1860 and later from 1907-1919 and attempts to determine which areas of the city had the …
