Linking Tree Cover Change To Historical Management Practices In Urban Parks, Sabine Nix, Lara A. Roman, Marc Healy, John Rogan, Hamil Pearsall

Geography

Context: Urban tree canopy (UTC) in parks is shaped by complex interactions between social and ecological processes over decades. To understand UTC change in parks, it is critical to identify and characterize the unique set of social processes that drive long-term change. Objectives: We sought to uncover the feedbacks between social processes and long-term UTC changes in parks of a post-industrial city that experienced substantial population loss and park disinvestment. Methods: Our mixed-methods approach involved quantifying spatiotemporal UTC changes and connecting those changes to historical management practices for three parks in Philadelphia, PA (US). We delineated UTC using aerial imagery …

Rocky Mountain Forests Are Poised To Recover Following Bark Beetle Outbreaks But With Altered Composition, Kyle C. Rodman, Robert A. Andrus, Amanda R. Carlson, Trevor A. Carter, Teresa B. Chapman, Jonathan D. Coop, Paula J. Fornwalt, Nathan S. Gill, Brian J. Harvey, Ashley E. Hoffman, Katharine C. Kelsey, Dominik Kulakowski, Daniel C. Laughlin, Jenna E. Morris, José F. Negrón, Katherine M. Nigro, Gregory S. Pappas, Miranda D. Redmond, Charles C. Rhoades, Monique E. Rocca, Zoe H. Schapira, Jason S. Sibold, Camille S. Stevens-Rumann, Thomas T. Veblen, Jianmin Wang, Xiaoyang Zhang, Sarah J. Hart

Geography

Amplified by warming temperatures and drought, recent outbreaks of native bark beetles (Curculionidae: Scolytinae) have caused extensive tree mortality throughout Europe and North America. Despite their ubiquitous nature and important effects on ecosystems, forest recovery following such disturbances is poorly understood, particularly across regions with varying abiotic conditions and outbreak effects. To better understand post-outbreak recovery across a topographically complex region, we synthesized data from 16 field studies spanning subalpine forests in the Southern Rocky Mountains, USA. From 1997 to 2019, these forests were heavily affected by outbreaks of three native bark beetle species (Dendroctonus ponderosae, Dendroctonus rufipennis and Dryocoetes …

The Pacific Drought Knowledge Exchange: A Co-Production Approach To Deliver Climate Resources To User Groups, Ryan J. Longman, Abby G. Frazier, Christian P. Giardina, Elliott W. Parsons, Sierra Mcdaniel

Geography

Drought is a growing threat to hydrological, ecological, agricultural, and socio-cultural systems of the tropics, especially tropical islands of the Pacific where severe droughts can compromise food and water security. Overcoming barriers to knowledge sharing between land managers and researchers is a critical cross-sector strategy for engaging and mitigating or adapting to drought. Here we describe the establishment and functioning of the Pacific Drought Knowledge Exchange (PDKE), which provides users with easier access to: (1) sector- and geography-specific climate information; (2) better and more comprehensive information; (3) improved technical assistance; and (4) a more collaborative information-transfer environment through participation in …

The Influence Of Burn Severity On Post-Fire Spectral Recovery Of Three Fires In The Southern Rocky Mountains, Jaclyn Guz, Florencia Sangermano, Dominik Kulakowski

Geography

Increased wildfire activity and altered post-fire climate in the Southern Rocky Mountains has the potential to influence forest resilience. The Southern Rocky Mountains are a leading edge of climate change and have experienced record-breaking fires in recent years. The change in post-fire regeneration and forest resilience could potentially include future ecological trajectories. In this paper, we examined patterns of post-fire spectral recovery using Landsat time series. Additionally, we utilized random forest models to analyze the impact of climate and burn severity on three fire events in the Southern Rocky Mountains. Fifteen years following the fires, none of the burned stands …

Applying Landscape Fragmentation Analysis To Icescape Environments: Potential Impacts For The Pacific Walrus (Odobenus Rosmarus Divergens), Anthony Himmelberger, K E. Frey, Florencia Sangermano

Geography

Sea-ice cover across the Arctic has declined rapidly over the past several decades owing to amplified climate warming. The Pacific walrus (Odobenus rosmarus divergens) relies on sea-ice floes in the St. Lawrence Island (SLI) and Wainwright regions of the Bering and Chukchi seas surrounding Alaska as a platform for rest, feeding and reproduction. Lower concentrations of thick ice floes are generally associated with earlier seasonal fragmentation and shorter annual persistence of sea-ice cover, potentially affecting the life history of the Pacific walrus. In this study, 24 Landsat satellite images were classified into thick ice, thin ice or open water to …

Behavior And Chemical Signals As Markers Of Colony Identification In Argentine Ants (Linepithema Humile), Stephanie A. Rohrbach

College of Graduate Studies: Theses & Dissertations

Argentine ants, Linepithema humile, are a highly successful invasive species around the globe and are especially prominent in states such as California and the southeastern United States. L.humile have a unique form of unicoloniality, called “supercolonies”. L. humile can detect colonymates through scent markers in their outer cuticle. With these chemical markers, ants will exhibit high aggression if they smell different from one another. In our study, we performed aggression assays among ten different nest sites and analyzed their CHCs through gas chromatography mass spectrometry, or GC-MS, analysis. For our behavior results, while within-nest interactions displayed low aggression as …

Chinese Neoglobalization In East Africa: Logics, Couplings And Impacts, Pádraig R. Carmody, James T. Murphy

Geography

The most significant case of transnational state capitalism today is China's Belt and Road Initiative (BRI) which seeks to expand/extend the country's geoeconomic and geopolitical integrations globally. We conceptualise the BRI as manifest principally through industrial offshoring, infrastructure investments and exports from China. These vectors articulate with particular places, forming transnational couplings that shape development outcomes. We examine the BRI's couplings and their development implications in the East African countries of Djibouti, Ethiopia and Kenya where China has engaged significantly. We demonstrate the contingent manner of BRI's variegations; its pragmatism, flexibility, and limitations as a hegemonic or developmental project.

A Pantropical Assessment Of Deforestation Caused By Industrial Mining, Stefan Giljum, Victor Maus, Nikolas Kuschnig, Sebastian Luckeneder, Michael Tost, Laura J. Sonter, Anthony J. Bebbington

Geography

Growing demand for minerals continues to drive deforestation worldwide. Tropical forests are particularly vulnerable to the environmental impacts of mining and mineral processing. Many local- to regional-scale studies document extensive, long-lasting impacts of mining on biodiversity and ecosystem services. However, the full scope of deforestation induced by industrial mining across the tropics is yet unknown. Here, we present a biome-wide assessment to show where industrial mine expansion has caused the most deforestation from 2000 to 2019. We find that 3,264 km2 of forest was directly lost due to industrial mining, with 80% occurring in only four countries: Indonesia, Brazil, Ghana, …

Emerging Hot Spot Analysis To Indicate Forest Conservation Priorities And Efficacy On Regional To Continental Scales: A Study Of Forest Change In Selva Maya 2000-2020, Nicholas Cuba, Laura A. Sauls, Anthony J. Bebbington, Denise Humphreys Bebbington, Avecita Chicchon, Pilar Delpino Marimón, Oscar Diaz, Susanna Hecht, Susan Kandel, Tracey Osborne, Rebecca Ray, Madelyn Rivera, John Rogan, Viviana Zalles

Geography

Despite the importance of preserving contiguous tropical forest areas to maintain biodiversity and terrestrial carbon stocks, methodological challenges continue to hinder broad-scale analysis of threats to these forests. Emerging Hot Spot Analysis (EHSA) is a spatial-statistical method that conveys complex information about the temporal dynamics of deforestation across a range of moderate to coarse spatial scales. Using Global Forest Change (GFC) data as inputs, EHSA produces spatially comprehensive, gridded outputs that represent a standardized, reproduceable way to instantiate contiguous forest tracts as spatial objects. Doing so allows aggregation of other GFC-derived values and analysis of alternative geographic configurations besides sub-national …

Borderlands And Mestiza Consciousness In Appalachia: Latina Undergraduate Experiences In A Predominantly White Institution, Susana Mazuelas Quirce

Graduate Theses, Dissertations, and Problem Reports (ETD)

This qualitative phenomenological study explores the experiences of eight undergraduate Latinas in a Predominantly White Institution in the Appalachian region using Gloria Anzaldúa’s insights on Borderlands and Mestiza consciousness. A vast majority of the studies focused on the Latinx college student population that takes place in states and tertiary institutions with a dense concentration of Latinx population, leaving rural areas—especially the Appalachian region— unexplored. There is, as well, a scarcity of studies in research focused on four-year-degree-granting institutions in which Latinx are highly underrepresented. A substantial number of studies continue presenting Latinx students as a homogenous group despite their heterogeneity …

Jue Insight: Migration, Transportation Infrastructure, And The Spatial Transmission Of Covid-19 In China, Bingjing Li, Lin Ma

Research Collection School Of Economics

This paper evaluates the impacts of migration flows and transportation infrastructure on the spatial transmission of COVID-19 in China. Prefectures with larger bilateral migration flows and shorter travel distances with Hubei, the epicenter of the outbreak, experienced a wider spread of COVID-19. In addition, richer prefectures with higher incomes were better able to contain the virus at the early stages of community transmission. Using a spatial general equilibrium model, we show that around 28% of the infections outside Hubei province can be explained by the rapid development in transportation infrastructure and the liberalization of migration restrictions in the recent decade.

Wages For Climate Stewardship?, Sayd Randle

Research Collection College of Integrative Studies

IN 1996, environmental historian Richard White published an essay with a title borrowed from a pissed-off bumper sticker: “Are You an Environmentalist or Do You Work for a Living?” White used the frictions between loggers and spotted owl advocates in the Pacific Northwest to show readers exactly how US-based environmentalism had come to be seen as orthogonal to productive labor. “Work,” he asserted, is in fact “where we should begin” when we talk about environmentalism. Set aside idealized images of natural spaces as best suited for leisure, he counseled. It’s only “[i]n taking responsibility for our own lives and work, …

The Socio-Economic Factors Of Poverty: Empirical Evidence From District Lasbela, Balochistan, Fida Muhammad, Parvez Ahmed Shaikh, Hazrat Yousaf

Business Review

Poverty is defined as a lack of basic necessities for survival. The current study examines the socio-economic factors that contribute to poverty in five of the district of Lasbela's nine tehsils, namely (Bela, Dureji, Hub, Sonmiani, and Uthal. Lasbela is Balochistan's tenth most deprived district, located near Karachi. The data for this study is cross-sectional and contributed from the project's 2014 Base Line Survey (BLS, 2014). The Logit model was used to evaluate the variables under study in order to achieve the study goal. According to our empirical findings, the average daily income in this district was less than $1.50. …

Southern Humboldt Indians, Jerry Rohde

Trade & Scholarly Monographs

More than a century after they had spoken, these early day Indians will be heard. All of us who make Humboldt County our home deserve to have access to this information. We deserve to know the many, many names of the tribal groups that were once here and to learn the story of these groups. And we deserve to know the names of the Indian elders who transmitted these names and told these stories, just as we deserve to know the stories about the elders themselves.

This is the 2024 second printing, which includes minor updates.

Can Californian Households Save Money On Transportation Costs By Living In Transit-Oriented Developments (Tods)?, Hongwei Dong

Mineta Transportation Institute

Many residents in large Californian metropolitan areas are heavily burdened by housing costs. Advocates, researchers, and elected officials in California are debating whether transit-oriented development (TOD) could be an effective tool to mitigate the housing affordability problem by increasing housing supply and reducing transportation costs in transit-rich neighborhoods. This study contributes to this debate by estimating how much Californian families can save on transportation costs by living in transit-oriented developments (TODs). By utilizing the confidential version of the 2010–2012 California Household Travel Survey, this study evaluates the impact of TOD on household transportation expenditures by comparing TOD households with two …

Condominium: A Transformative Innovation In Property And Local Government, Douglas C. Harris

All Faculty Publications

Condominium is a form of ownership that produces separate parcels of land and a structure of local government within multi-unit developments. As one form of common interest community, condominium packages private property with a co-ownership interest in common property and rights to participate in the governing organisation. A statutory innovation, the condominium form has been adopted in jurisdictions around the world and has quickly become the dominant form of land ownership for new-build housing in many cities. As an increasingly prominent feature of urban real estate, condominium is changing the nature of ownership and of local government, and is one …

To Scale Dragons: Comprising Things Lost And Two Essays On Fantasy, André V. Katkov

Open Access Dissertations

To Scale Dragons comprises two essays on fantasy and a fantasy manuscript, which together form a critical-creative study of fantasy as a cross-media genre of art. In the first essay, “Fantasy as Hypernatural Art: A Look at the Genre’s Chthulucentric Coalescence,” I provide a theoretical foundation for fantasy as art, looking to key developments in the history of fantasy and fantasy criticism to propose a new set of core properties for fantasy as a fuzzy set, à la Brian Attebery, and defend an understanding of fantasy as the art of constructing and conveying immersive hypernature. In particular, I argue that …

The American Lobster (Homarus Americanus) In Narragansett Bay During A Time Of Ecosystem Flux: Temperature, Predation, And Larval Dynamics, Kristin Huizenga

Open Access Dissertations

The American lobster (Homarus americanus) in southern New England sustained a particularly prosperous fishery during the 1980s and 1990s. However, in 2001 lobsters in the region began to decline, leading to the eventual collapse of the fishery in Rhode Island. The Narragansett Bay was no exception to this trend, with the number of lobsters caught by the University of Rhode Island Graduate School of Oceanography weekly fish trawl survey peaking in the 1990s before the decline. Today, few lobsters are caught in the Bay.

This dissertation seeks to identify whether environmental stressors and predators drive lobster populations in …

Structural And Petrologic Insights Into The Emplacement Of Effusive Silicic Lavas: Inyo Domes, California, Shelby L. Isom

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Long Valley volcanic region, eastern California, USA is most famous for the caldera-forming eruption which produced the Bishop Tuff ~760,000 years ago. Over the last 3,000 years volcanism has been focused in the western margin of the region through punctuated eruptions of silicic lavas and domes. Three simultaneous effusive silicic eruptions, ~600 years ago, generated three lava domes: Obsidian Dome; Glass Creek Dome; and Deadman Dome which erupted onto vastly different topographies. These domes are exceptionally unique as they erupted variable amounts of two textural and chemical endmember lavas (crystal-rich and crystal-poor) that intimately mixed. The overarching goal of …

The U.S. Coal Industry: Market Structure & Implications, Sara Elizabeth Guffey

Graduate Theses, Dissertations, and Problem Reports (ETD)

The U.S. coal mining industry was once a booming industry which created and defined communities, particularly in Appalachia. The industry has, however, transformed significantly in the last couple of decades with the passage of environmental policies, with competition from the Shale Revolution, from changes in company ownership, and from mine safety regulation. Overall, the coal industry during this time has experienced a massive decline in production and employment. This dissertation is composed of three papers that investigate these mechanisms and their role in understanding market structure, coal transactions and prices, and mine safety outcomes. Motivated by the shutdowns of U.S. …

The world of American politics continues to infiltrate households across the United States as technological advancement extends the reach of breaking news and government action. With this expanding reach, communities all over the country are digesting and contemplating their place in national politics more fervently than ever. At the crux of this discussion is the backbone of political engagement and action—identity and its resulting political attitudes. For decades, partisanship has been a point of contention amongst American citizens. Cities across the nation showcase protests, demonstrations, town hall meetings, and more illustrating citizens’ care for their democratized input in government affairs. …

Critical Perspectives On Produce Prescription Programs & Us Federal Nutrition Policy, Alanna K. Higgins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Produce prescription programs, interventions operating at the intersection of food access and public health, are steadily increasing in number across the United States since 2010. I leverage key informant interviews, participant observations, and event ethnographies to form a four-year institutional ethnography of the implementation of produce prescriptions within West Virginia alongside a legal-policy archaeology methodology to understand how produce prescriptions have been institutionalized and funded within the US Farm Bill. While much of produce prescription program growth is attributed to an expansion of federal funding starting in 2014, this dissertation demonstrates that these programs and the federal legislation which has …

An Examination Of Career Orientation Courses And College Students' Career Decision Self-Efficacy, Logan R. Mayhew

Graduate Theses, Dissertations, and Problem Reports (ETD)

Career development is an ongoing concern for college administrators as the modern knowledge era generates new and fluctuating jobs. College students are more anxious than in previous decades about starting their careers and making vocational decisions. Building career decision self-efficacy in students results in greater feelings of confidence and increases demonstration of career-related behaviors. Students in three online career courses at West Virginia University were assessed for gains in career decision self-efficacy in comparison with a control group after participation in the courses and compared on the basis of gender. Results of a mixed ANOVA indicated a significant increase in …

Human Welfare & Emergencies: Education, Natality, And Violence, Erika Antolin Davies

Graduate Theses, Dissertations, and Problem Reports (ETD)

I identify changes in human action during emergencies such as heavy precipitation and shelter-in-place orders. In two chapters I explore the effects of precipitation on educational attainment and birth rates as residential broadband access increases. In my third chapter I identify the movement of pets in and out of the home as a trigger for domestic violence during the COVID-19 lockdown. I estimate difference-in-difference regressions with panel data, coming to three conclusions. First: educational attainment in Appalachia is stunted by precipitation, as students have difficulty getting to school in bad weather. As this historically under-educated region of the US gains …

Gun Culture 3.0, Andrew Phillip Stover

Graduate Theses, Dissertations, and Problem Reports (ETD)

There exist a criminology of firearms and an epidemiology of firearms use, but little in the way of a sociology of U.S. firearm ownership. Most social science study of firearms concerns illicit gun use and the harm that use produces. Compared to this body of work, little has been done to explore the culture of legal gun ownership. A few social scientists have attempted to change this by contributing their own interpretations of what a sociology of U.S. gun ownership might look like. Professor David Yamane, in doing just this, has posited a cultural model of contemporary gun ownership he …

The aim of this dissertation was to investigate how recent processes of land-change induced by humans contributed to the shaping and alteration of the current landscape in a headwater system of Central Appalachians in West Virginia (US), to understand the interactions and tradeoffs among ecosystems services and address potential solutions for targeting more sustainable human-environment interactions in a region that is deeply grounded on extractive economies. The multitiered objective was addressed through different research phases in order to unfold and disentangle a series of complex problems that the study area presents. Three main phases were used; they corresponded to distinct …

Understanding Surface Water--Groundwater Connectivity And Discharge In Arctic Deltas, Lindsey N. Aman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Increased warming is driving unprecedented hydrologic changes within arctic deltas with implications for water storage, solute processing, and terrestrial and marine ecology. Thermokarst lakes within Arctic deltas store flood waters and filter solutes and sediments, thus moderating the impact of flood water discharge to arctic seas. However, this moderating influence is diminishing as lakes shrink on annual and seasonal time scales, especially close to active channels where lakes are shrinking most rapidly. This study investigates surface water-groundwater connectivity in arctic delta plains with coupled flow and heat transport models to provide a mechanistic understanding of how lake-channel proximity will impact …
