Defending The Homeland: An Archaeoethnodemographic (Aed) Analysis Of Population Dynamics And Settlement Patterns In The Navajo Dinétah, Ad 1720–1745, Kurt Mantonya

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation presents an innovative archaeoethnodemographic (AED) analysis of Navajo population dynamics during the Middle Period (AD 1720−1745) of the Gobernador Phase in the Dinétah, the ancestral Navajo homeland in northwest New Mexico. During this critical quarter-century, intensified Ute and Comanche slave-raiding and Spanish military expeditions forced the Diné to abandon traditional dispersed settlement patterns in favor of defensive aggregation around fortified pueblitos—small masonry defensive structures built on boulder-tops and mesa-rims throughout the region.

The study employs an AED framework that systematically integrates archaeological site analysis, ethnographic household organization data, historical documentation, and demographic modeling to reconstruct population dynamics during …

A Preliminary Examination Of Sexual And Physical Victimization 6 Months After Recent Rape, Kate Walsh, Amanda K. Gilmore, Anna E. Jaffe, Patricia Frazier, Linda Ledray, Ron Acierno, Kenneth J. Ruggiero, Dean G. Kilpatrick, Heidi S. Resnick

Department of Psychology: Faculty Publications

One in four US women will experience a completed or attempted rape in their lifetime, and more than 50% of survivors will experience two or more rapes. Rape and physical violence also co-occur. Multiple experiences of sexual and physical violence are associated with elevated mental and physical health problems. This secondary analysis examined the prevalence and correlates of experiencing sexual or physical violence within 6 months of a sexual assault medical forensic exam (SAMFE). Between May 2009 and December 2013, 233 female rape survivors aged 15 and older were enrolled in a randomized controlled trial during a SAMFE in the …

Changing Fire Regimes And Nuanced Impacts On A Critically Imperiled Species, Jeremy T. Rockweit, Katie M. Dugger, Damon B. Lesmeister, Raymond J. Davis, Alan B. Franklin, J. Mark Higley

United States Department of Agriculture Wildlife Services: Staff Publications

Wildfire activity throughout western North America is increasing which can have important consequences for species persistence. Native species have evolved disturbance-adapted traits that confer resilience to natural disturbance provided disturbances operate within their historical range of variability. This resilience can erode as disturbance regimes change and begin operating outside this range. We assessed wildfire impacts during 1987–2018 on the northern spotted owl, an imperiled species with complex relationships with late and early seral forest in the Pacific Northwest, USA. We analyzed population- and individual-level wildfire impacts across the frequent-fire portion of the owl’s geographic range at two spatial scales and …

Generativity Development Among College Students Who Mentor: A Sequential Multi-Method Quantitative Study., Hannah Sunderman, Lindsay J. Hastings

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

Purpose Generativity, defined as care for the next generation, is a hallmark of developmental theory (Erikson, 1950). Mentoring is an antecedent to generativity (Doerwald et al., 2021), with college students who mentor demonstrating higher generativity than their peers (Hastings et al., 2015). Yet, no research has studied generativity development longitudinally among college students who mentor.

Design/methodology/approach Using MANCOVA analyses, Study One (N = 91) cross-sectionally examined the influence of years spent mentoring on generativity levels among college students who mentor in the United States. Study Two (N = 44) employed growth curve analyses (GCA) in multilevel modeling (MLM) …

Tourism‑Supported Working Lands Sustain A Growing Jaguar Population In The Colombian Llanos, Matthew Hyde, Esteban Payán, Jorge Barragan, Diana Stasiukynas, Sanmantha Rincón, William L. Kendall, Jerónimo Rodríguez, Kevin R. Crooks, Stewart W. Breck, Valerie Boron

United States Department of Agriculture Wildlife Services: Staff Publications

Understanding large carnivore demography on human-dominated lands is a priority to inform conservation strategies, yet few studies examine long-term trends. Jaguars (Panthera onca) are one such species whose population trends and survival rates remain unknown across working lands. We integrated nine years of camera trap data and tourist photos to estimate jaguar density, survival, abundance, and probability of tourist sightings on a working ranch and tourism destination in Colombia. We found that abundance increased from five individuals in 2014 to 28 in 2022, and density increased from 1.88 ± 0.87 per 100 km² in 2014 to 3.80 …

United States Department of Agriculture Wildlife Services: Staff Publications

The northern spotted owl (Strix occidentalis caurina; hereinafter NSO) was listed as “threatened” under the Endangered Species Act in 1990 and population declines have continued since that listing. Given the species’ protected status, any proposed activities on Federal lands that might impact NSO require consultation with U.S. Fish and Wildlife Service and part of that consultation often includes surveys to determine presence and occupancy status of the species in the proposed activity area. The objective of this report is to present study-area specific estimates of the probability of detection for NSO pairs from twelve 2-week seasonal survey periods …

Editorial: C. Elegans Host-Microbiome Interactions: From Medical To Ecological And Evolutionary Model, Michael A. Herman, Javier E. Irazoqui, Buck S. Samuel, Nic Vega

School of Biological Sciences: Faculty Publications

Microbiomes often form specific functional associations with their hosts. Correlations between microbiome membership and states of host health and disease abound in many systems. However, there are few systems that allow for in depth functional studies that include precise manipulation and interrogation of both microbiome composition and host function. Recently the nematode Caenorhabditis elegans - an excellent genetic model organism for studying many fields of biology, including neurobiology and behavior, development, cell biology, and innate immunity - has proven to be a robust system to probe microbiome interactions and their effect on host physiology.

An Efficient Method Of Evaluating Multiple Concurrent Management Actions On Invasive Populations, Amy J. Davis, Randy Farrar, Brad Jump, Parker Hall, Travis Guerrant, Kim M. Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Evaluating the efficacy of management actions to control invasive species is crucial for maintaining funding and to provide feedback for the continual improvement of management efforts. However, it is often difficult to assess the efficacy of control methods due to limited resources for monitoring. Managers may view effort on monitoring as effort taken away from performing management actions. We developed a method to estimate invasive species abundance, evaluate management effectiveness, and evaluate population growth over time from a combination of removal activities (e.g., trapping, ground shooting) using only data collected during removal efforts (method of removal, date, location, number of …

Conserving Endangered Black-Footed Ferrets: Biological Threats, Political Challenges, And Lessons Learned, Travis M. Livieri, Steven C. Forrest, Marc R. Matchett, Stewart Breck

United States Department of Agriculture Wildlife Services: Staff Publications

There may be few stories in the annals of wildlife management that are as dramatic as the near demise and comeback of the black-footed ferret (Mustela nigripes). Endemic only to North America, this charming little carnivore found only in the continent’s central grasslands was hardly known to science until the mid-20th century. By then, vast colonies of the prey it depended on for food and shelter, the prairie dog (Cynomys spp.), had been wiped out through disease (sylvatic plague) and an agricultural industry with little tolerance for burrowing and grazing rodents. At its low point, the species’ …

The northern spotted owl (Strix occidentalis caurina) inhabits older coniferous forests in the Pacific Northwest and has been at the center of forest management issues in this region. The immediate threats to this federally listed species include habitat loss and competition with barred owls (Strix varia), which invaded from eastern North America. We conducted a prospective meta-analysis to assess population trends and factors affecting those trends in northern spotted owls using 26 years of survey and capture-recapture data from 11 study areas across the owls' geographic range to analyze demographic traits, rates of population change, and occupancy parameters for spotted …

Evaluating Potential Effects Of Solar Power Facilities On Wildlife From An Animal Behavior Perspective, Rachel Y. Chock, Barbara Clucas, Elizabeth K. Peterson, Bradley Blackwell, Daniel T. Blumstein, Kathleen Church, Esteban Fernández-Juricic, Gabriel Francescoli, Alison L. Greggor, Paul Kemp, Gabriela M. Pinho, Peter M. Sanzenbacher, Bruce A. Schulte, Pauline Toni

United States Department of Agriculture Wildlife Services: Staff Publications

Solar power is a renewable energy source with great potential to help meet increasing global energy demands and reduce our reliance on fossil fuels. However, research is scarce on how solar facilities affect wildlife. With input from professionals in ecology, conservation, and energy, we conducted a research-prioritization process and identified key questions needed to better understand impacts of solar facilities on wildlife. We focused on animal behavior, which can be used to identify population responses before mortality or other fitness consequences are documented. Behavioral studies can also offer approaches to understand the mechanisms leading to negative interactions (e.g., collision, singeing, …

Effects Of The Met: Live In Hd On The Democratization Of Opera In America, Anna Wigtil

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

The Met: Live in HD satellite broadcasts of live opera performances began in 2006 and have since become popular with audiences around the world. While this could be an excellent avenue to democratize opera and make it available to new audiences, the available data indicates that most Live in HD viewers are already opera enthusiasts and have previously attended live opera performances. This thesis examines the history of the Metropolitan Opera’s broadcasting efforts, the demographics of American opera audiences, trends in Live in HD’s repertoire, and strategies to increase Live in HD’s appeal to a broader, more diverse …

The History, Evolution, And Trends Of Academic Dishonesty: A Literature Review, Amy Zachek

The Nebraska Educator: A Student-Led Journal

Academic dishonesty is a murky problem without a commonly agreed upon solution in American higher education. It has a long-standing history in higher education but a short history in academic literature, it has evolved rapidly and longitudinally (McCabe & Trevino, 1996), and it has several easily apparent trends and others that the majority of researchers are in disagreement about. While traversing this perilous landscape of dichotomies, this paper will examine connections and gaps in the literature, make suggestions and recommendations for future study based off of these results, and examine the implications that these recommendations could have on higher education …

Individual And Population Fitness Consequences Associated With Large Carnivore Use Of Residential Development, Heather Johnson, David L. Lewis, Stewart W. Breck

United States Department of Agriculture Wildlife Services: Staff Publications

Large carnivores are negotiating increasingly developed landscapes, but little is known about how such behavioral plasticity influences their demographic rates and population trends. Some investigators have suggested that the ability of carnivores to behaviorally adapt to human development will enable their persistence, and yet, others have suggested that such landscapes are likely to serve as population sinks or ecological traps. To understand how plasticity in black bear (Ursus americanus) use of residential development influences their population dynamics, we conducted a 6-yr study near Durango, Colorado, USA. Using space-use data on individual bears, we examined the influence of use of residential …

Annotated Bibliography Of Scientific Research On Greater Sage-Grouse Published From 2015 To 2019, Sarah K. Carter, Robert S. Arkle, Heidi L. Bencin, Benjamin R. Harms, Daniel J. Manier, Aaron N. Johnston, Susan L. Phillips, Steven E. Hanser, Zachary H. Bowen

United States Geological Survey: Publications

The greater sage-grouse (Centrocercus urophasianus; hereafter GRSG) has been a focus of scientific investigation and management action for the past two decades. The 2015 U.S. Fish and Wildlife Service listing determination of “not warranted” was in part due to a large-scale collaborative effort to develop strategies to conserve GRSG populations and their habitat and to reduce threats to both. New scientific information augments existing knowledge and can help inform updates or modifications to existing plans for managing GRSG and sagebrush ecosystems. However, the sheer number of scientific publications can be a challenge for managers tasked with evaluating and …

The Impacts Of Family Stem Events For Young Children On Parents' Perceptions In A Rural Remote School, Cheyenne Jeffers

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

STEM education is an interdisciplinary approach to creating learning experiences, preparing the children of today to become the workforce and global citizens of a digital tomorrow. Young children are natural explorers of their world, participating in STEM learning through real world experiences. Public and parental misconceptions are hurdles to implementing STEM learning with young children. Many believe young children are not capable of participating in STEM learning and should be taught foundational skills first. On the contrary, STEM learning should be a priority in the educational environment of young children, most beneficially combining efforts at home as well as at …

This Is Not A Library! This Is Not A Kwik-E-Mart! The Satire Of Libraries, Librarians And Reference Desk Air-Hockey Tables, Casey D. Hoeve

University of Nebraska-Lincoln Libraries: Faculty Publications

Librarians are obsessed with stereotypes. Sometimes even so much so that, according to Gretchen Keer and Andrew Carlos, the fixation has become a stereotype within itself (63). The complexity of the library places the profession in a constant state of transition. Maintaining traditional organization systems while addressing new information trends distorts our image to the outside observer and leaves us vulnerable to mislabeling and stereotypes. Perhaps our greatest fear in recognizing stereotypes is not that we appear invariable but that the public does not fully understand what services we can provide. When we lose our ability to maintain relevancy, we …

The Conundrum Of Agenda-Driven Science In Conservation, M. Zachariah Peery, Gavin M. Jones, R. J. Gutierrez, Steve M. Redpath, Alan B. Franklin, Daniel Simberloff, Monica G. Turner, Volker C. Radeloff, Gary C. White

United States Department of Agriculture Wildlife Services: Staff Publications

Conservation biology is a value-laden discipline predicated on conserving biodiversity (Soulé 1985), a mission that does not always sit easily with objective science (Lackey 2007; Pielke 2007; Scott et al. 2007). While some encourage scientists to be responsible advocates for conservation (Garrard et al. 2016), others worry that objectivity in conservation research may suffer (Lackey 2007). At this time, we believe advocacy by scientists is essential for environmental conservation and, indeed, humanity. It is difficult to envision the state of our environment had scientists failed to encourage policy makers and the public to address emerging conservation problems. Nevertheless, conservation scientists …

Trust In The Jury System As A Predictor Of Juror/Jury Decisions, Kimberly S. Dellapaolera, Bailey A. Barnes, Brian H. Bornstein

UCARE: Research Products

To determine whether jurors’ attitudes are correlated with their verdicts and judgments at trial, the present experiments examined the relationship between individuals’ trust in the jury system, other legal attitudes, and their verdict judgments, at both the individual (juror) and group (jury) level. We used a binary logistic regression model to examine the factors—jury instructions and individual difference measures—that contribute to a juror’s verdict. The results indicate that jurors with higher PJAQ and JUST scores had a higher likelihood of voting guilty on a homicide trial involving a mercy killing. It was also found that the majority of juries in …

Time-Lagged Effects Of Weather On Plant Demography: Drought And Astragalus Scaphoides, Brigitte Tenhumberg, Elizabeth E. Crone, Satu Ramula, Andrew J. Tyre

School of Biological Sciences: Faculty Publications

Temperature and precipitation determine the conditions where plant species can occur. Despite their significance, to date, surprisingly few demographic field studies have considered the effects of abiotic drivers. This is problematic because anticipating the effect of global climate change on plant population viability requires understanding how weather variables affect population dynamics. One possible reason for omitting the effect of weather variables in demographic studies is the difficulty in detecting tight associations between vital rates and environmental drivers. In this paper, we applied Functional Linear Models (FLMs) to long-term demographic data of the perennial wildflower, Astragalus scaphoides, and explored sensitivity of …

Fertility And Infertility: Toward An Integrative Research Agenda, Katherine M. Johnson, Arthur L. Greil, Karina M. Shreffler, Julia Mcquillan

Department of Sociology: Faculty Publications

In this article, we show that social science research on fertility and infertility consists of largely separate research traditions, despite shared interest in pregnancies and births (or lack thereof). We describe four ways these two traditions differ: (1) publication trajectories and outlets, (2) fields of study and major theoretical frameworks, (3) degree of attention to the other topic, and (4) language and definitions used. We then discuss why future integration of these bodies of research would be beneficial, outline potential steps toward rapprochement, and provide common areas of dialogue that could facilitate and enrich these bodies of research. We offer …

Grass Is Not Always Greener: Rodenticide Exposure Of A Threatened Species Near Marijuana Growing Operations, Alan B. Franklin, Peter C. Carlson, Angela Rex, Jeremy T.

Marijuana (Cannabis spp.) growing operations (MGO) in California have increased substantially since the mid-1990s. One environmental side-effect of MGOs is the extensive use of anticoagulant rodenticides (AR) to prevent damage to marijuana plants caused by wild rodents. In association with a long-term demographic study, we report on an observation of brodifacoum AR exposure in a threatened species, the northern spotted owl (Strix occidentalis caurina), found freshly dead within 669–1347 m of at least seven active MGOs.

A Framework For Linking Population Model Development With Ecological Risk Assessment Objectives, Sandy Raimondo, Matthew Etterson, Nathan Pollesch, Kristina Garber, Andrew Kanarek, Wade Lehmann, Jill Awkerman

United States Environmental Protection Agency: Publications

The value of models that link organism-level impacts to the responses of a population in ecological risk assessments (ERAs) has been demonstrated extensively over the past few decades. There is little debate about the utility of these models to translate multiple organism-level endpoints into a holistic interpretation of effect to the population; however, there continues to be a struggle for actual application of these models as a common practice in ERA. Although general frameworks for developing models for ERA have been proposed, there is limited guidance on when models should be used, in what form, and how to interpret model …

Factors That Influence Vital Rates Of Seaside And Saltmarsh Sparrows In Coastal New Jersey, Usa, Samuel G. Roberts, Rebecca A. Longenecker, Matthew A. Etterson, Katharine J. Ruskin, Chris S. Elphick, Brian J. Olsen, W. Gregory Shriver

United States Environmental Protection Agency: Publications

As saltmarsh habitat continues to disappear, understanding the factors that influence the population dynamics of saltmarsh breeding birds is an important step in the conservation of these declining species. Using 5 yrs (2011–2015) of demographic data, we evaluated and compared apparent adult survival and nest survival of Seaside (Ammodramus maritimus) and Saltmarsh (A. caudacutus) sparrows at the Edwin B. Forsythe National Wildlife Refuge in New Jersey, USA. We determined the effect of site management history (unditched vs. ditched marshes) on adult and nest survival to aid in prioritizing future management or restoration actions. Apparent adult …
