The state of Michigan is not solely the lower portion or in other words the “mitten.” It is a combination of the lower and upper peninsula. The Upper Peninsula of Michigan (abbreviated the “UP”) is the upper portion of Michigan that is surrounded on three sides by three different Great Lakes: Lake Superior, Lake Michigan, and Lake Huron. It connects to the Lower Peninsula of Michigan by the Mackinac Bridge which crosses five miles across the Straits of Mackinac.
The counties of the Eastern Upper Peninsula are Alger, Chippewa, Luce, Mackinac, and Schoolcraft. They are marked by large stretches of …
The Rise Of Anti-Immigration Populist Radical Right Parties: The Effect Of The Syrian Conflict On Refugee Resettlement And Migration Policies In Germany And Austria, Sara Kouchehbagh
Graduate Theses and Dissertations
The effects of Syrian migration in Europe have revolutionized refugee resettlement globally. Most immigration and refugee problems have historically been settled similarly post WWII, however, Syria is the largest refugee crisis since WWII. It is important to learn how to respond to future conflicts with displacement and resettlement affecting Western countries that are unprepared to respond to a conflict of such magnitude. This thesis will compare previous conflicts and the Syrian conflict, while highlighting the resilient political momentum of reactionary new political groups in European states, particularly Germany and Austria.
The research and results from this study will include data …

Improving Earthquake Disaster Models With Post-Event Data: Insights From The 2015 Gorkha, Nepal Earthquake, Bradley Steven Wilson
Graduate Theses and Dissertations
Immense amounts of data are collected following earthquake disasters. Yet, it remains unclear how researchers’ might take full advantage of diverse post-disaster datasets. Using data from the 2015 Gorkha Nepal earthquake, this dissertation explores three ways in which post- disaster survey and assessment datasets can be used to inform models of seismic risk, vulnerability, and recovery processes. The first article presents an empirical analysis of scale issues in disaster vulnerability indices using a novel dataset of 750,000 households. This study finds that using aggregated household data to create social vulnerability indices can produce results that are meaningfully different from equivalent …

Globally, protected areas offer refugia for a broad range of taxa including threatened and endangered species. In the United States (US), the National Park Service (NPS) manages public lands to preserve biodiversity, but increasing park visitation and development of surrounding landscapes increase exposure to and effects from bioactive contaminants. The risk (exposure and hazard) to NPS protected-stream ecosystems within the highly urbanized southeast region (SER) from bioactive contaminants was assessed in five systems based on 334 pesticide and pharmaceutical analytes in water and 119 pesticides in sediment. Contaminant mixtures were common across all sampled systems, with approximately 24% of the …

Relationships Between Soil Macroinvertebrates And Nonnative Feral Pigs (Sus Scrofa) In Hawaiian Tropical Montane Wet Forests, Nathaniel H. Wehr, Creighton M. Litton, Noa K. Lincoln, Steven C. Hess
United States National Park Service: Publications
Abstract Nonnative feral pigs (Sus scrofa) are recognized throughout the New World as a highly significant introduced species in terms of ecosystem alteration. Similarly, nonnative soil macroinvertebrates (e.g. earthworms, ground beetles) invade and alter the structure and function of native habitats globally. However, the relationship between feral pigs and soil macroinvertebrates remains largely unknown. This study analyzed relationships between these taxa using nine sites located inside and outside of feral pig management units representing a * 25 year chronosequence of removal in tropical montane wet forests in Hawai‘i. Soil macroinvertebrates were sampled from plots categorized as: actively trampled by feral …
Community Forest In Liberia: The Interface Between Sustainable Charcoal Production And Deforestation, Amavie Clement
Community Forest In Liberia: The Interface Between Sustainable Charcoal Production And Deforestation, Amavie Clement
Capstone Collection
The available data establishes a direct correlation between charcoal production and forest degradation and deforestation in Liberia. Charcoal is the primary energy source for Liberians, especially in urban areas where the bulk of the population lives. It is expected to be the mainstay energy source for years to come because it is affordable, accessible, and convenient to use compared to other forms of energy (i.e. electricity and petroleum gas). However, the current model of charcoal production, based on indiscriminate felling of trees, poses a danger to the environment as it results in widespread forest degradation and deforestation. Therefore, any successful …

Understanding the spatial ecology of highly mobile marine vertebrates is necessary for informing conservation and management strategies aimed at protecting such species. Buck Island Reef National Monument (BIRNM), off the coast of St. Croix, US Virgin Islands, harbors critical foraging habitat for Critically Endangered juvenile hawksbills Eretmochelys imbricata that exhibit high site fidelity until sexual maturation. Using an array of fixed passive acoustic receivers that covered over 20.2 km2 at its largest configuration and in-water biannual sampling, we analyzed residency patterns and habitat use of 29 hawksbills. High recapture rates allowed for long- term data collection for some individuals, with …
Coffee Is Not Forever : A Global History Of The Coffee Leaf Rust, Stuart Mccook
Coffee Is Not Forever : A Global History Of The Coffee Leaf Rust, Stuart Mccook
Ohio University Press Open Access Books
The global coffee industry, which fuels the livelihoods of farmers, entrepreneurs, and consumers around the world, rests on fragile ecological foundations. In Coffee Is Not Forever, Stuart McCook explores the transnational story of this essential crop through a history of one of its most devastating diseases, the coffee leaf rust. He deftly synthesizes agricultural, social, and economic histories with plant genetics and plant pathology to investigate the increasing interdependence of the world’s coffee-producing zones. In the process, he illuminates the progress and prognosis of the challenges—especially climate change—that pose an existential threat to a crop that global consumers often take …
Chronic Kidney Disease From Non-Traditional Causes Throughout Central America, Abigail K. Watson
Chronic Kidney Disease From Non-Traditional Causes Throughout Central America, Abigail K. Watson
Senior Theses
Throughout many Central American countries, incidence of chronic kidney disease (CKD) has been on the rise. The disease mainly affects agricultural workers and differs from typical CKD. Patients in these countries often do not have preexisting conditions such as diabetes or hypertension known to be traditional causes of CKD. They also experience increased damage to the kidney tubules, rather than the glomeruli generally more heavily impacted. There has been speculation regarding the causes of CKDnT (chronic kidney disease of nontraditional causes), but no consensus has been reached. Two major hypotheses to explain the high prevalence among Central American sugarcane workers …

Nonlinear Reaction–Diffusion Process Models Improve Inference For Population Dynamics, Xinyi Lu, Perry J. Williams, Mevin B. Hooten, James A. Powell, Jamie N. Womble, Michael R. Bower
United States National Park Service: Publications
Partial differential equations (PDEs) are a useful tool for modeling spatiotemporal dynamics of ecological processes. However, as an ecological process evolves, we need statistical models that can adapt to changing dynamics as new data are collected. We developed a model that combines an ecological diffusion equation and logistic growth to characterize colonization processes of a population that establishes long-term equilibrium over a heterogeneous environment. We also developed a homogenization strategy to statistically upscale the PDE for faster computation and adopted a hierarchical framework to accommodate multiple data sources collected at different spatial scales. We highlighted the advantages of using a …
Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman
Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman
United States National Park Service: Publications
Permafrost thaw in the Arctic is mobilizing old carbon (C) from soils to aquatic ecosystems and the atmosphere. Little is known, however, about the assimilation of old C by aquatic food webs in Arctic watersheds. Here, we used C isotopes (d13C, D14C) to quantify C assimilation by biota across 12 streams in arctic Alaska. Streams spanned watersheds with varying permafrost hydrology, from ice-poor bedrock to ice-rich loess (that is, yedoma). We measured isotopic content of (1) C sources including dissolved organic C (DOC), dissolved inorganic C (DIC), and soil C, and (2) stream biota, including benthic biofilm and macroinvertebrates, and …
Sedimenting Territory: A Political Geology Of Oil, Earth, And Spatial Politics In Turkey, Zeynep Oguz
Sedimenting Territory: A Political Geology Of Oil, Earth, And Spatial Politics In Turkey, Zeynep Oguz
Dissertations, Theses, and Capstone Projects
Building on the recent turn to the material and earthly aspects of resources and political power in environmental anthropology and political geography, this work historically and ethnographically examines the kinds of territorial politics that oil’s materiality, geological qualities, and infrastructures have generated in Turkey. Despite being surrounded by oil-rich neighbors in the Middle East, Turkey’s domestic oil reserves supply only 7 percent of the country’s oil, all of which has been drilled in the Kurdish provinces of Batman, Diyarbakır, and Adıyaman in Turkey’s southeast, where the PKK (Kurdistan Workers’ Party) has been fighting the Turkish state since 1984 for cultural …

Commmunity, Ecology, And Modernity: Faunal Analysis Of Skútustaðir In Mývatnssveit, Northern Iceland, Megan Hicks
Dissertations, Theses, and Capstone Projects
This dissertation examines the archaeofaunal remains from Skútustaðir, a middle to high-status farm in Mývatnssveit, Northern Iceland, to understand the experience of rural communities and their ecologies during Iceland’s transition from regulated colonial exchange to a capitalist economy during the 17th through 19th centuries. Archaeofaunal analysis is used to reconstruct changes in the ways that people herded, hunted, and fished, providing insights into how they managed their local environments for subsistence and novel contexts of exchange. In addition to archaeofaunal analysis, primary textual sources are explored to assess how the Skútustaðir household and its rural community mobilized long-term …

Social Interactions Do Not Drive Territory Aggregation In A Grassland Songbird, S.K. Winnicki, S.M. Munguia, E.J. Williams, W.A. Boyle
United States National Park Service: Publications
Understanding the drivers of animal distributions is a fundamental goal of ecology and informs habitat management. The costs and benefits of colonial aggregations in animals are well established, but the factors leading to aggregation in territorial animals remain unclear. Territorial animals might aggregate to facilitate social behavior such as (1) group defense from predators and/or parasites, (2) cooperative care of offspring, (3) extra-pair mating, and/or (4) mitigating costs of extra-pair mating through kin selection. Using experimental and observational methods, we tested predictions of all four hypotheses in a tallgrass prairie in northeast Kansas, United States. Grasshopper Sparrow (Ammodramus savannarum) males …

A Moral Panic Over Cats, William S. Lynn, Francisco J. Santiago-Ávila, Joann Lindenmayer, John Hadidian, Arian D. Wallach, Barbara J. King
Stray and Feral Animal Populations Collection
Some conservationists believe that free-ranging cats pose an enormous risk to biodiversity and public health and therefore should be eliminated from the landscape by any means necessary. They further claim that those who question the science or ethics behind their arguments are science deniers (merchants of doubt) seeking to mislead the public. As much as we share a commitment to conservation of biodiversity and wild nature, we believe these ideas are wrong and fuel an unwarranted moral panic over cats. Those who question the ecological or epidemiological status of cats are not science deniers, and it is a false analogy …
