The Emergence Of Ecosystems-Based Fisheries Management From The Groundfish Crisis In New England: An Actor-Network Theory Analysis, Catherine King Sep 2020

The Emergence Of Ecosystems-Based Fisheries Management From The Groundfish Crisis In New England: An Actor-Network Theory Analysis, Catherine King

Dissertations, Theses, and Capstone Projects

This research investigates the emergence of ecosystems-based fisheries management (EBFM) for New England's marine fisheries in the context of the "crisis" that is escalating in its groundfish fishery. Close observations of the practices of fisheries scientists in coordination with managers at the New England Fisheries Management Council, with focus on how knowledge is being produced and employed, allows for understanding EBFM as an emergent construction produced by networks of associations between actants, human and non-human, material and semiotic, and not strictly as a policy prescription informed by experts on biology, ecology, and socio-economics. This analysis identifies and elucidates the multiplicity …


Data And Information As Our New Transport Infrastructure: An Exploration Into How The Modern Transport System Is Being Shaped By Information Communication Technology, Adam Davidson Sep 2020

Data And Information As Our New Transport Infrastructure: An Exploration Into How The Modern Transport System Is Being Shaped By Information Communication Technology, Adam Davidson

Dissertations, Theses, and Capstone Projects

This dissertation is focuses on the role that data and information has in creating and altering behavior related to transportation. To do so, it lays out a theoretical model of technological transition and then follows it up with three case studies. The theoretical model provides a structure to consider how different actors in our transportation ecosystem – users, firms, policy actors – mix with technological evolution to uphold or incrementally recreate our transportation landscape. The case studies stand on their own to highlight important findings about how data and information are impacting transportation scenarios, but collectively reinforce the theoretical models. …

“Wilderness” Revisited: Is Canadian Park Management Moving Beyond The “Wilderness” Ethic?, Megan Youdelis, Roberta Nakoochee, Colin O'Neil, Elizabeth Lunstrum, Robin Roth Jul 2020

“Wilderness” Revisited: Is Canadian Park Management Moving Beyond The “Wilderness” Ethic?, Megan Youdelis, Roberta Nakoochee, Colin O'Neil, Elizabeth Lunstrum, Robin Roth

Global Studies Faculty Publications and Presentations

This paper questions whether the rescaling of conservation practice in Canada to include local and Indigenous communities, NGOs, and private market-based actors represents a move away from wilderness-thinking in conservation, and what implications this might have for the future of conservation in Canada. We explore the links between Cronon's “wilderness” ethic and coloniality, racism/sexism/classism, and political economy, and the extent to which recent trends in conservation practice, such as co-management arrangements, private tourism proposals, and a shift in programming to attract a diverse public to parks, help us to move beyond the limited vision for conservation and environmentalism that the …

How Globalization, Sustainability, And Human Impacts Are Affecting Two Major Mexican Cities: Mexico City And Guadalajara, Cristina Sedano Jun 2020

How Globalization, Sustainability, And Human Impacts Are Affecting Two Major Mexican Cities: Mexico City And Guadalajara, Cristina Sedano

Electronic Theses, Projects, and Dissertations

Mexico is one of the richest countries in the world, not in terms of economic stability but in terms of natural resources, culture, and atmosphere. When people think of Mexico, they usually think of the high-tension relationship with the United States, their neighboring country to the North. Although there are many diverse historical and present-day characteristics of Mexico, most associate the county with the high levels of crime due to narco and cartels, the high levels of poverty in regional areas, and to some just a party destination. Unbeknownst to many is the thousands year old culture that is passed …


Using Historical Maps For Contaminated Site Identification And Prediction, And Environmental Justice Implications: A Case Study In Grand Rapids, Michigan, Dana Heusinkveld Jun 2020

Using Historical Maps For Contaminated Site Identification And Prediction, And Environmental Justice Implications: A Case Study In Grand Rapids, Michigan, Dana Heusinkveld

Masters Theses

As the production of synthetic chemicals has grown in the past centuries to increase production, lower costs, and generally make our lives more convenient, detecting and understanding the environmental impacts of these compounds has lagged significantly behind their mass production and wide-spread use. To combat this trend, sources of these contaminants, especially those that have been removed from the landscape, need to be quickly identified to make mitigation and remediation efforts more effective. In this study, historical Sanborn maps are used to extract and digitize historical site/land use in Grand Rapids during the early 1900s through the practical application of …


Labor, Land Use, And The Luxury City, Samuel Stein Jun 2020

Labor, Land Use, And The Luxury City, Samuel Stein

Dissertations, Theses, and Capstone Projects

Labor, Land Use, and the Luxury City is an examination into the entanglements of working-class organizations, real estate capital, and state planning in 20th and 21st century New York City. Through theoretical inquiry, historical interpretation, and contemporary analysis, I investigate the motivations – both internally generated and externally imposed – that guide New York City unions’ and non-profits’ decision-making around questions of land use and gentrification. These institutions maintain a complex set of relationships to both real estate capital and the real estate state, leading many unions and non-profits to either support land use changes that accelerate gentrification or negotiate …


Hijab In The Indonesian National Struggle, Mangesti Rahayu May 2020

Hijab In The Indonesian National Struggle, Mangesti Rahayu

International Review of Humanities Studies

Fashion and history cannot be separated, because fashion is one indicator of a change in culture, civilization, behavior, and certain identities. Vice versa, changes and developments in fashion are influenced by conditions at the time the fashion is developing, both the social, cultural, political, religious, economic and others. Fashion that is developing in Indonesia is Muslim fashion. One part of Muslim clothing is the hijab, headgear worn by Muslim women. Hijab is not only part of religious observance, hijab is already part of fashion and we can examine the hijab style of a society from its historical period. We can …

Food and climate are closely intertwined, with the high-emissions U.S. industrial food system contributing to climate change, while a changing climate produces new food system vulnerabilities, which will particularly impact those of the least means. This research is premised on the need to transform our food system, and to define what this vision looks like at the local level, while centering questions of power, justice and rights. It explores how groups, organizations and individuals engaged in local food system change envision transformation and understand corresponding social justice concerns, in a changing climate. It looks at opportunities for food and climate …


Development Of A Modified Floristic Quality Index As A Rapid Habitat Assessment Method In The Northern Everglades, Rebakah E. Gibble, Donatto D. Surratt May 2020

Development Of A Modified Floristic Quality Index As A Rapid Habitat Assessment Method In The Northern Everglades, Rebakah E. Gibble, Donatto D. Surratt

United States National Park Service: Publications

Floristic quality assessments (FQA) using floristic quality indices (FQIs) are useful tools for assessing and comparing vegetation communities and related habitat condition. However, intensive vegetation surveys requiring significant time and technical expertise are necessary, which limits the use of FQIs in environmental monitoring programs. This study modified standard FQI methods to develop a rapid assessment method for characterizing and modeling change in wetland habitat condition in the northern Everglades. Method modifications include limiting vegetation surveys to a subset of taxa selected as indicators of impact and eliminating richness and/or abundance factors from the equation. These modifications reduce the amount of …


Fire Monitoring Handbook May 2020

Fire Monitoring Handbook

United States National Park Service: Publications

Fire is a powerful and enduring force that has had, and will continue to have, a profound influence on National Park Service (NPS) lands. Fire management decisions within the National Park Service require information on fire behavior and on the effects of fire on park resources. With good reason, the public is holding park management increasingly accountable, especially in the area of fire management. Federal and state agencies are instituting progressively more stringent guidelines for burning, monitoring, and evaluation. The impetus behind these guidelines and the purpose of this handbook are to ensure that management objectives are being met, to …

Sylvan Dell Field Station Student Projects

The Sylvan Dell Nature Preserve and Farm in South Williamsport, PA. Sylvan Dell is a 229 acre plot of farmland that contains a wetland on the south section of the property. It lies just south of the West Branch of the Susquehanna River. The first humans we know of to settle on this land were the Susquehannock and later the Haudenosaunee (Iroquois) Native Americans. In the late 18th century, white settlers took the land away from the Haudenosaunee. In the 20th century, the famous ornithologist Robert Porter Allen was influenced by the broad range of bird species that would visit …


What Drives Commercial Poaching?: From Poverty To Economic Inequality, Elizabeth Lunstrum, Nícia Givá May 2020

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 …

Show Me St. Louis: Risk Assessment Through An 80-20 Framework, Hannah K. Steinman

Graduate Theses and Dissertations

Researchers of crime and place have long explored the uneven distribution of crime within the built environment and repeatedly identified where crime is concentrated. The longstanding question pertaining to crime at the micro-level, is why crime concentrates. This study operates within environmental criminology, through an 80-20 framework, to explore the spatial distribution of crime across streets with crime generators and attractors in St. Louis, Missouri to fill this gap in the literature. A conjunctive analysis of case configurations is used to identify unique high and low-crime street profiles. Crime data from 2018 – 2019 are used from the St. Louis …


Memorialization On College Campuses Today, Virginia Thornton Apr 2020

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 …

Drinking Water Governance For Whom? An Institutional Analysis Of Rural Drinking Water Systems In New Mexico, Tucker Colvin Apr 2020

Drinking Water Governance For Whom? An Institutional Analysis Of Rural Drinking Water Systems In New Mexico, Tucker Colvin

Geography ETDs

Rural community drinking water systems in New Mexico are facing many challenges, including a lack of personnel, deteriorating infrastructure, lack of funds, overly burdensome and confusing regulation, environmental concerns, and concerns over water rights. Governing agencies are creating vulnerability by making managers prioritize some issues and neglect others. Water systems designated a Mutual Domestic Water Consumers Associations are especially problematic because they are small and managed by volunteers but have as much regulatory burden as larger municipalities. I use the theory of institutional work to explain how an institution that was originally designed to help low-income and rural communities is …

Dead Wolf To Red Wolf: Virginia Reintroduction Habitat Suitability, Hector Gomez Apr 2020

Dead Wolf To Red Wolf: Virginia Reintroduction Habitat Suitability, Hector Gomez

Environmental Studies Senior Seminar Projects

Red wolves (Canis Rufus) are the most endangered species of wolves. All red wolves currently in the wild are in the Albemarle Peninsula in North Carolina. Red wolf population in the Albemarle decreased from a peak of around 113-149 wolves in 2014 to 15-17 wolves in 2021. Most red wolf mortalities for this wild population occurred from anthropogenic causes such as accidental shooting, poaching, and vehicle strikes. The purpose of this study is to assess the suitability of the Delmarva Peninsula as a potential reintroduction site for another red wolf population. To do so I analyzed the land cover, deer …


Acoustically Advertising Male Harbour Seals In Southeast Alaska Do Not Make Biologically Relevant Acoustic Adjustments In The Presence Of Vessel Noise, Leanna P. Matthews, Michelle E.H. Fournet, Christine Gabriele, Holger Klinck, Susan E. Parks Mar 2020

Acoustically Advertising Male Harbour Seals In Southeast Alaska Do Not Make Biologically Relevant Acoustic Adjustments In The Presence Of Vessel Noise, Leanna P. Matthews, Michelle E.H. Fournet, Christine Gabriele, Holger Klinck, Susan E. Parks

United States National Park Service: Publications

Aquatically breeding harbour seal (Phoca vitulina) males use underwater vocalizations during the breeding season to establish underwater territories, defend territories against intruder males, and possibly to attract females. Vessel noise overlaps in frequency with these vocalizations and could negatively impact breeding success by limiting communication space. In this study, we investigated whether harbour seals employed anti-masking strategies to maintain communication in the presence of vessel noise in Glacier Bay National Park and Preserve, Alaska. Harbour seals in this location did not sufficiently adjust source levels or acoustic parameters of vocalizations to compensate for acoustic masking. Instead, for every 1 dB …

United States National Park Service: Publications

Context In human-dominated landscapes, habitat fragmentation and barriers to movement can interrupt gene flow. While often considered at a local extent, regional analyses are also needed to reveal broader landscape-mediated population processes.

Objectives To explore the relationship between patterns of gene flow and fragmentation resulting from urbanization across southern California, we used the bobcat as an indicator species. We assembled data for a landscape level genetic analysis across southern California from both archived and new samples, including two northern Californian populations for comparison, to identify local and regional areas affected by isolation.

Methods Our regional analyses focused on a dataset …


Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors Mar 2020

Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors

United States National Park Service: Publications

Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 percent of 1–3 anthropogenic carbon dioxide emissions. Climate-driven vegetation models 4,5 typically predict that this tropical forest ‘carbon sink’ will continue for decades . Here we assess trends in the carbon sink using 244 structurally intact African tropical forests spanning 11 countries, compare them with 321 published plots from Amazonia and investigate the underlying drivers of the trends. The carbon sink in live aboveground biomass in intact African tropical forests has been stable for the three decades to …
