Remembering East Frisian Immigrants Who Settled Near German Valley, Illinois: A Family History Scrapbook, Derek M. Heeren
Remembering East Frisian Immigrants Who Settled Near German Valley, Illinois: A Family History Scrapbook, Derek M. Heeren
Genealogy Resources
In June of 1848, Jelle Heeren (age 25) married Taalke Park (age 15) near Rhauderfhen, East Friesland (German: Ostfriesland). One year later, on September 10, along with their infant son, they left everything that was familiar to them in Germany. Based on glowing reports of good opportunities for farming and raising a family on the American frontier, they set sail for the United States. After what must have been a traumatic voyage (including the death of their son), they entered the United States at New York City. Continuing onward, they arrived at a new East Frisian settlement in Illinois (later …

Animal social interactions have an intrinsic spatial basis as many of these interactions occur in spatial proximity. This presents a dilemma when determining causality: Do individuals interact socially because they happen to share space, or do they share space because they are socially linked? We present a method that uses demographic turnover events as a natural experiment to investigate the links between social associations and space use in the context of interannual winter site fidelity in a migratory bird. We previously found that golden-crowned sparrows (Zonotrichia atricapilla) show consistent flocking relationships across years, and that familiarity between individuals …
Real Depth-Correction In Ground Penetrating Radar Data Analysis For Bridge Deck Evaluation, Sepehr Pashoutani, Jinying Zhu
Real Depth-Correction In Ground Penetrating Radar Data Analysis For Bridge Deck Evaluation, Sepehr Pashoutani, Jinying Zhu
Department of Civil and Environmental Engineering: Faculty Publications
When ground penetrating radar (GPR) is used for the non-destructive evaluation of concrete bridge decks, the rebar reflection amplitudes should be corrected for rebar depths to account for the geometric spreading and material attenuation of the electromagnetic wave in concrete. Most current depth-correction methods assume a constant EM wave velocity in the entire bridge deck and correct GPR amplitudes based on the two-way travel time (TWTT) instead of the actual rebar depth. In this paper, we proposed a depth-correction algorithm based on the real rebar depths. To compare different depth-correction methods, we used gprMax software to simulate GPR signals in …

Department of Child, Youth, and Family Studies: Faculty Publications
Introduction: Globally, 27 million female refugees of reproductive age are subjected to numerous socio-ecological factors that increase their risks of mental health issues, especially during the postpartum period. This study seeks to explore Syrian refugee mothers’ experiences and perceptions of postpartum depression.
Methods: We used a qualitative phenomenological approach to interview purposively sampled typical postpartum Syrian mothers living in informal camps in Lebanon to evaluate their maternal mental health perceptions, coping strategies, and help-seeking practices.
Results: Results revealed three major themes: conceptualizing maternal depression as extraordinary and ordinary, cultural perceptions of mental health help-seeking, and coping with negative emotions.

Understanding the genetic diversity and mechanisms underlying genetic variation in pathogen populations is crucial to the development of effective control strategies. We investigated the genetic diversity and reproductive biology of Colletotrichum graminicola isolates which infect maize by sequencing the genomes of 108 isolates collected from 14 countries using restriction site-associated DNA sequencing (RAD-seq) and wholegenome sequencing (WGS). Clustering analyses based on single-nucleotide polymorphisms revealed three genetic groups delimited by continental origin, compatible with short-dispersal of the pathogen and geographic subdivision. Intra- and intercontinental migration was observed between Europe and South America, likely associated with the movement of contaminated germplasm. Low …
Migratory Connectivity Of North American Waterfowl Across Administrative Flyways, Anthony Roberts, Amy L. Scarpignato, Allison Huysman, Jeffrey A. Hostetler, Emily B. Cohen
Migratory Connectivity Of North American Waterfowl Across Administrative Flyways, Anthony Roberts, Amy L. Scarpignato, Allison Huysman, Jeffrey A. Hostetler, Emily B. Cohen
United States Fish and Wildlife: Staff Publications
Management of waterfowl that migrate seasonally across North America occurs within four flyways that were delineated in the early 1900s to include the annual movements of populations. Movements may have changed over the past century since the administrative flyways were established, and may do so while management plans are in use, so information about transitions among flyways through time can illustrate how management assumptions may change. Today there are more than 12 million records from 60 years of migratory waterfowl band recoveries to assess adaptive management approaches that will be most effective when they account for movements within and between …

Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled the annual and seasonal population dynamics of a common pest, Helicoverpa zea (Boddie), based on three overwintering suitability zones throughout North America using four decades of soil temperatures: the southern range (able to persist through winter), transitional zone (uncertain overwintering survivorship), and northern limits (unable to survive winter). Our model indicates H. zea population dynamics are hierarchically structured with continental-level effects that …
The Intersections Of Migration And Identity In Young Adult Literature Of The French-Speaking World, Kaitlyn Waller
The Intersections Of Migration And Identity In Young Adult Literature Of The French-Speaking World, Kaitlyn Waller
Department of Modern Languages and Literatures: Dissertations, Theses, and Student Research
Both young adult literature and novels of migration frequently deal with the construction of identity, from coming-of-age stories to narratives of intercultural exploration and hybridization. Young adult narratives of migration, then, represent a fascinating intersection of two literary traditions for the exploration of questions of identity. However, young adult literature and its varied subgenres are often overlooked among the broader critical scholarship of migration narratives. Indeed, the genre is often critiqued as too simplistic or pedagogical to truly merit consideration among adult readers and academics. Through an in-depth analysis of nine novels, however, I explore questions of identity development in …
Migration And Trauma: Memory And The Myths Of El Otro Lado, Elva Moreno Del Rio
Migration And Trauma: Memory And The Myths Of El Otro Lado, Elva Moreno Del Rio
Department of English: Dissertations, Theses, and Student Research
This thesis is composed of two parts that scrutinize the myth of the United States
and el cuento of El Otro Lado. The first part titled, “The Illness Rooted in the American Myth” connects the U.S. myth to J. Hector St. John de Crevecoeur’s piece Letters from an American Farmer, published in 1782. In analyzing the writings of Toni Morrison, James Baldwin, and Eden E. Torres, I indentify the impact that Crevecoeur’s myth had on Black, Indigenous and other people of color. This research illustrates the physical and psychological effects that these ideologies have on the mind and body of …
Climate Change Adaptation, Migration, And Promising Developments For Pacific Island States, Ashley Jonas
Climate Change Adaptation, Migration, And Promising Developments For Pacific Island States, Ashley Jonas
Honors Theses
The people of the Pacific Islands face an existential crisis due to climate change, despite the fact that they are the least responsible for contributing to carbon emissions. The effects of climate change, namely sea-level rise, pose a verified threat to low-lying islands, infiltrating water supplies, crops, and infrastructure. As a result, there is a need for improved solutions for adapting to the impacts of climate change and for easier access to legal migration pathways when the consequences are insurmountable. Through comparative discourse analysis of scholarly sources, intergovernmental policies, and non-governmental organizations, the thesis finds that Small Island Developing States …

Effects Of Release Techniques On Parent-Reared Whooping Cranes In The Eastern Migratory Population, Hillary L. Thompson, M. Susanna Glass, Marianne M. Wellington, Kim H. Boardman, Glenn H. Olsen
Proceedings of the North American Crane Workshop
Reintroduction of an Eastern Migratory Population (EMP) of whooping cranes (Grus americana) in the United States by release of captive-reared individuals began in 2001. As of 2020, the EMP has approximately 21 breeding pairs and has had limited recruitment of wild-hatched individuals, thus captive-reared juveniles continue to be released into breeding areas in Wisconsin to maintain the population. We investigated the effects of release techniques on survival, behavior, site fidelity, and conspecific associations of 42 captive-parent-reared whooping cranes released during 2013-2019 into the EMP. Individuals were monitored intensively post-release, then as a part of a long-term monitoring program, …

Department of Teaching, Learning, and Teacher Education: Faculty Publications
Purpose—In an editorial introduction essay for the special issue on Religion, Literacies, and English Education in Global Dialogue, the editors frame papers in the special issue in dialogue with previous scholarly literature around three central lines of inquiry: How do children, youth and families navigate relationships among religion, spirituality, language and literacy? What challenges are faced by language and literacy teachers and teacher educators around the globe who seek to respond to diverse religious and spiritual perspectives in their work? And what opportunities do teachers seize or create toward this end? How are developments of language and literacy theory, …
Changing Faces And Persistent Patterns For Education In The New Latinx Diaspora, Edmund T. Hamann, Linda Harklau
Changing Faces And Persistent Patterns For Education In The New Latinx Diaspora, Edmund T. Hamann, Linda Harklau
Department of Teaching, Learning, and Teacher Education: Faculty Publications
The study of education in the New Latino/a/x1 Diaspora (NLD) was initiated in the 1990s with an understanding that education research from regions where the Latino/a/x presence is long-standing might not always fit well for places where Latino/a/x populations were newer and where histories of discrimination, political organizing, and resistance were much more limited. This chapter is the fourth in a series of "bigger picture" examinations of the status of education in the NLD over the past two decades (following Hamann, Wortham, and Murillo [2002] and Hamann and Harklau [2010, 2015]). Like previous iterations, this chapter points to gaps …
Whooping Crane Stay Length In Relation To Stopover Site Characteristics, Andrew J. Caven, Aaron T. Pearse, David A. Brandt, Mary J. Harner, Greg D. Wright, David M. Baasch, Emma M. Brinley Buckley, Kristine L. Metzger, Matthew R. Rabbe,, Anne E. Lacy
Whooping Crane Stay Length In Relation To Stopover Site Characteristics, Andrew J. Caven, Aaron T. Pearse, David A. Brandt, Mary J. Harner, Greg D. Wright, David M. Baasch, Emma M. Brinley Buckley, Kristine L. Metzger, Matthew R. Rabbe,, Anne E. Lacy
Proceedings of the North American Crane Workshop
Whooping crane (Grus americana) migratory stopovers can vary in length from hours to more than a month. Stopover sites provide food resources and safety essential for the completion of migration. Factors such as weather, climate, demographics of migrating groups, and physiological condition of migrants influence migratory movements of cranes (Gruidae) to varying degrees. However, little research has examined the relationship between habitat characteristics and stopover stay length in cranes. Site quality may relate to stay length with longer stays that allow individuals to improve body condition, or with shorter stays because of increased foraging efficiency. We examined this …

Male Mastodon Landscape Use Changed With Maturation (Late Pleistocene, North America), Joshua H. Miller, Daniel C. Fisher, Brooke E. Crowley, Ross Secord, Bledar A. Konomi
Department of Earth and Atmospheric Sciences: Faculty Publications
Under harsh Pleistocene climates, migration and other forms of seasonally patterned landscape use were likely critical for reproductive success of mastodons (Mammut americanum) and other megafauna. However, little is known about how their geographic ranges and mobility fluctuated seasonally or changed with sexual maturity. We used a spatially explicit movement model that coupled strontium and oxygen isotopes from two serially sampled intervals (5+ adolescent years and 3+ adult years) in a male mastodon tusk to test for changes in landscape use associated with maturation and reproductive phenology. The mastodon’s early adolescent home range was geographically restricted, with no evidence of …

Members of the order Carnivora are a unique and important seed disperser who consume and deposit undamaged seeds while providing regular long-distance seed dispersal opportunities. Some members of Carnivora, such as coyotes (Canis latrans), are undergoing range expansions which may help the plant species they consume colonize new locations or replace dispersal services provided by recently extirpated species. In this study, we evaluated aspects of the seed dispersal effectiveness of coyotes and gut passage time to determine the potential dispersal distances for three commonly consumed and commonly occurring plant species (Amelanchier alnifolia, Celtis ehrenbergiana, and Juniperus osteosperma). We also investigated …

Der Kormoran Phalacrocorax Carbo In Der Mongolei, Michael Stubbe, Lucie Marie Baltz, Davaa Lchagvasuren, Lukas Kratzsch, Lara-Sophie Dey, Annegret Stubbe
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
The Great Cormorant Phalacrocorax carbo is a wide spread breeding species in Mongolia with a progressive population trend. Observations of the Mongolian-German Biological Expeditions were analyzed and summarized with data from literature. About 1,500 young birds were ringed in 2016 and 2017. One important recovery was coming from the wintering area Mai Po Marshes Nature Reserve of Hong Kong. It is unclear if all Mongolian Cormorants are flying at the same route to their wintering region in South China. The main feeding fishes in Mongolia belong to endemic species of the genus Oreoleuciscus (Cyprinidae). Measurements of 113 eggs from Tolbo- …
What Educators In Mexico And In The United States Need To Know And Acknowledge To Attend To The Educational Needs Of Transnational Students, Edmund T. Hamann, Víctor Zúñiga
What Educators In Mexico And In The United States Need To Know And Acknowledge To Attend To The Educational Needs Of Transnational Students, Edmund T. Hamann, Víctor Zúñiga
Department of Teaching, Learning, and Teacher Education: Faculty Publications
This chapter from the edited volume "The Students We Share" explains to both US and Mexican audiences that a persistent number and proportion of K-12 students continue to circulate between both countries and thus that it is a challenge for both countries' education systems—including teacher preparation, curriculum, assessment, etc.—to see how students' knowledge and experience from the other system is both salient to their new schooling in a new country and valuable for how it will contribute to their future means for negotiating adulthood.
Evidence For Continental-Scale Dispersal Of Antimicrobial Resistant Bacteria By Landfill-Foraging Gulls, Christina A. Ahlstrom, Mariëlle L. Van Toor, Hanna Woksepp, Jeffrey C. Chandler, John A.

Anthropogenic inputs into the environment may serve as sources of antimicrobial resistant bacteria and alter the ecology and population dynamics of synanthropic wild animals by providing supplemental forage. In this study, we used a combination of phenotypic and genomic approaches to characterize antimicrobial resistant indicator bacteria, animal telemetry to describe host movement patterns, and a novel modeling approach to combine information fromthese diverse data streams to investigate the acquisition and long-distance dispersal of antimicrobial resistant bacteria by landfill-foraging gulls. Our results provide evidence that gulls acquire antimicrobial resistant bacteria from anthropogenic sources, which they may subsequently disperse across and between …
Spatial Ecology And Resource Selection Of Bighorn Sheep (Ovis Canadensis) Ewes In A Prairie Badlands Population, Erin Wood
School of Natural Resources: Dissertations, Theses, and Student Research
The basic spatial ecology and habitat relationships of female bighorn sheep in Nebraska are poorly understood. Establishing seasonal patterns of space use and resource selection for this population at the margin of their historical and current range addresses a key knowledge gap and provides important baseline information for ongoing conservation efforts in Nebraska. We deployed GPS radio-collars on 56 adult ewes in western Nebraska to quantify seasonal space use, movements, and resource selection of ewes. To investigate spatial ecology, we quantified movements of ewes and the factors that influence home range size, seasonal use, and spatial stability across seasons. Home …

Migration ecology and habitat use of spring migrating birds using the Central Platte River is a well-explored topic, yet less is known about use of the North and South Platte rivers (NSPR) in western Nebraska. The efficiency and effectiveness of conservation efforts in the NSPR could be greatly improved with access to information about where and when birds roost and landscape prioritization tools. We used aerial surveys to determine population distribution and migration phenology of sandhill cranes Antigone canadensis, Canada geese Branta canadensis, and ducks using the NSPR for roosting during the mid-February to mid-April spring migration. We used these …

Migratory Flyways May Affect Population Structure In Double‐Crested Cormorants, Steven J.A. Kimble, Brian S. Dorr, Katie C. Hanson-Dorr, Olin E. Rhodes Jr., Travis L. Devault
USDA Wildlife Services: Staff Publications
Double‐crested cormorants (Phalacrocorax auritus) recovered from a demographic bottleneck so well that they are now considered a nuisance species at breeding and wintering grounds across the United States and Canada. Management of this species could be improved by refining genetic population boundaries and assigning individuals to their natal population. Further, recent radio‐telemetry data suggest the existence of Interior and Atlantic migratory flyways, which could reduce gene flow and result in substantial genetic isolation. In this study, we used 1,784 individuals collected across the eastern United States, a large panel of microsatellite markers developed for this species, and individuals banded as …
The Influence Of Isolated Thunderstorms And The Low-Level Wind Field On Nocturnally Migrating Birds In Central North America, Matthew V.D. Broeke, Timothy J. Gunkel
The Influence Of Isolated Thunderstorms And The Low-Level Wind Field On Nocturnally Migrating Birds In Central North America, Matthew V.D. Broeke, Timothy J. Gunkel
Department of Earth and Atmospheric Sciences: Faculty Publications
Seasonal bird migration occurs on large spatial scales and is influenced by many factors including weather conditions. Weather can include thunderstorms, which may force migrants to land or cause them to reroute a migration path. In this study, a sample of isolated thunderstorms was analyzed from the domains of three weather radars in the central United States to test hypotheses regarding the influence of thunderstorms on the distribution of migrants. Migrating bird density was often reduced in the wake of storms, and this wake reduction was typically more pronounced for larger, more intense and faster- moving storms, particularly in eastern …

Migration To The Us Among Rural Puerto Ricans Who Inject Drugs: Influential Factors, Sources Of Support, And Challenges For Harm Reduction Interventions, Roberto Abadie, Patrick Habecker, C. Gelpi-Acosta, Kirk Dombrowski
Department of Sociology: Faculty Publications
Background: While PWID of Puerto Rican origin have been migrating to the US for decades, the range of factors influencing their migration to the US and the resources they draw on to do so are not well understood. This is particularly true for rural Puerto Rican PWID, and the present study is the first empirical research to document migration patterns among this population. The specificities of their migration raise important challenges that need to be documented in order to implement more effective harm reduction policies at home (Puerto Rico) and abroad (US).
Methods: This paper draws from data obtained employing …
The Kaiparowits Puebloans: Kayentan Or Virgin Branch Migrants?, Phil R. Geib
The Kaiparowits Puebloans: Kayentan Or Virgin Branch Migrants?, Phil R. Geib
Department of Anthropology: Faculty Publications
More than 50 years ago archaeologists identified a high-density of small Puebloan habitations on the Kaiparowits Plateau in southern Utah. Analysis of pottery from these habitations by James Gunnerson and Florence Lister resulted in conflicting interpretations of cultural affiliation. Gunnerson argued for a Virgin affiliation whereas Lister argued for a Kayentan affiliation. Lister’s interpretation triumphed and the Puebloan occupation of the Kaiparowits was attributed to a migration of Kayenta people from the south during the late Pueblo II period. A review of architectural and artifactual evidence fails to support a Kayentan migration. An expansion of Puebloan groups from the west …

This Spanish-language chapter, drawn from a larger book intended to advise Mexico's new national leadership on various issues related to migration, focuses on the steadily growing, overlapping populations of US-born and US-school-experienced children in youth now enrolled in Mexican schools. It notes that that population, numbering more than 600,000, is enrolled all across Mexico, albeit not equally distributed, with municipios (counties) with high international migration rates also hosting high return rates. Moreover it notes that this population's US school experiences were highly varied not only because of their different durations, but because schooling in urban Southern California varies from that …
Seasonal Dynamics Of Lipid Metabolism And Energy Storage In The Brazilian Free-Tailed Bat, Elizabeth J. Rogers, Amie S. Sommers, Liam P. Mcguire
Seasonal Dynamics Of Lipid Metabolism And Energy Storage In The Brazilian Free-Tailed Bat, Elizabeth J. Rogers, Amie S. Sommers, Liam P. Mcguire
School of Natural Resources: Faculty Publications
As small, flying, mammalian endotherms, insectivorous bats are adapted to operate at high levels of energy expenditure. In response to seasonally variable challenges, we predicted that bats should balance energy budgets by flexibly adjusting aspects of their physiology or behavior in ways that elevate metabolic capacity. We examined variation in energy storage and pathways for oxidative metabolism in Brazilian free-tailed bats (Tadarida brasiliensis) related to estimated costs associated with reproduction and migration. We collected pectoral muscle and liver from female T. brasiliensis at six time points during the summer and fall and measured changes in the activity of four enzymes …
