Effective conservation for listed migratory species requires an understanding of how drivers of population decline vary spatially and temporally, as well as knowledge of range-wide connectivity between breeding and nonbreeding areas. Environmental conditions distant from breeding areas can have lasting effects on the demography of migratory species, yet these consequences are often the least understood. Our objectives were to 1) evaluate associations between survival and extreme environmental disturbances at nonbreeding areas, including hurricanes, harmful algal blooms, and oil spills, and 2) estimate migratory connectivity between breeding and nonbreeding areas of midcontinental piping plovers (Charadrius melodus). We used capture …

Brain Activity And Experiential Learning, Paul Witkovsky

National Collegiate Honors Council Monographs: Chapters

The chapters in this book deal primarily with students’ learning experiences as documented through self-awareness, knowledge acquisition, and behavior. Language makes it possible to communicate these changes to others. This essay, in contrast, will examine learning from the perspective of brain function. The current framework of thinking among neuroscientists, psychologists, and philosophers is that the brain is fully responsible for our minds, and thus studying how the brain functions in molecular, cellular, and systems terms sheds light on all mental processes, including those that are the substrate of learning. A scientific understanding of brain function thus helps to explain the …

Integrating Dynamic Systems Theory And City As Text™ Framework: In-Depth Reflections On ‘Lens’, Ron Weerheijm, Patricia Vuijk, Bernice Braid

National Collegiate Honors Council Monographs: Chapters

City as Text™ provides a semi-structured learning environment in which small groups of people are challenged to examine parts of a city through “mapping, observing, interpreting, analyzing, reflecting.” In 2014, I (Ron Weerheijm) attended a City as Text (CAT) Faculty Institute in Lyon. During an early session on the hills overlooking the eastern part of Lyon, our group observed a Basilique, the Notre Dame de Fourvière (1872–1884; interior finished 1964). Having a degree in architecture, I looked at this church from architectural and historical viewpoints. I was puzzled. In a quick scan, many different styles competed for my attention, hurting …

In this chapter, the authors outline the ongoing dialogues, thought processes, and pedagogical moves we make as two seasoned colleagues of color attempting to enhance the cultural competence of students through a critical multicultural education course offered at a public university-based teacher education program. We document how we address many enduring moral, ethical, and epistemological questions through our practice that are unique to educators of color working at predominantly white institutions (PWIs). We frame our work within the literature on diversity and social justice pedagogy and link our own work to the broader well-documented challenges faced by many educators of …

The Foster Care System: Domestic Abuse, Guadalupe Hernandez Rodriguez

Nebraska College Preparatory Academy: Senior Capstone Projects

In the United States, children not only experience domestic abuse at home but can also be an issue while placed in the foster care system. In the foster care system, the abuse suffered by these individuals is increased due to home instability. Abuse can take place in many forms (physical, emotional, economical, and sexual) and can occur in many places. It can become a life-threatening crime or a crime that affects an individual’s day-to-day life. The youth and young adults who pass through this system are left with physical injuries and adverse childhood experiences (abuse, neglect, and household dysfunction). The …

Why We Create Enemies, Jerry Mejia

Nebraska College Preparatory Academy: Senior Capstone Projects

Our enemies are not always distinguishable by features such as a black trench coat or twirly mustache. However, humans still attempt to characterize their enemies into a stereotype. This is to create a sense of calm-you know who your enemy is. This research topic explored why society requires a scapegoat to feel better about its own shortcomings. Even if the worst happens, at least we will know who to blame. This has been human nature for thousands of years and will continue to do so.

Cooperative Feeding In Common Dolphins As Suggested By Ontogenetic Patterns In Δ15N Bulk And Amino Acids, Rocio I. Ruiz-Cooley, Tim Gerrodette, Susan Chivers, Kerri Danil

United States Department of Commerce: Staff Publications

1. Understanding the effect of stage-specific traits on species feeding habits can reveal how natural selection shapes life strategies. Amino acid (AA) nitrogen stable isotopes (δ¹⁵N) provide multiple proxies of habitat baseline values and diet that can improve our understanding of species feeding strategies relative to their animal metabolism. We evaluated the effect of body length as a proxy for life stage and sex on the feeding habits of the common dolphin Delphinus delphis delphis using δ¹³C and δ¹⁵N in bulk tissue and AAs δ¹⁵N from skin samples collected for almost two …

Female And Male-Controlled Livestock Holdings Impact Pastoralist Food Security And Women’S Dietary Diversity, Henriette Gitungwa, Christopher Gustafson, E.Y. Jimenez, E. Wesley F. Peterson, M. Mwanzalila, Asha Makweta, E. Komba, R.R. Kazwala, J.A.K. Mazet, Elizabeth Vanwormer

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Food insecurity is a global problem that requires a One Health approach. As many households in low- and middle-income nations rely on crops and livestock that they produce to meet their household’s needs, food security and nutrition are closely linked to the health of animals and the environment. Resources controlled by women are more often allocated to uses that benefit the entire household, such as food, health, and educating children, than men’s resources. However, studies of gender control of resources among pastoralist societies are scant. We examined the effect of female and male control of livestock resources on food …

Pesticide Occurrence And Persistence Entering Recreational Lakes In Watersheds Of Varying Land Uses, Jessica Satiroff, Tiffany Messer, Aaron R. Mittelstet, Daniel D. Snow

Nebraska Water Center: Faculty Publications

Currently little is known of newer pesticide classes and their occurrence and persistence in recreational lakes. Therefore, the objectives of this study were to (1) assess average pesticide concentrations and loadings entering recreational lakes in three mixed land use watersheds throughout the growing season, (2) evaluate pesticide persistence longitudinally within the lakes, and (3) perform an ecotoxicity assessment. Six sampling campaigns were conducted at three lakes from April through October 2018 to measure the occurrence and persistence during pre, middle, and post growing season. Polar organic chemical integrative samplers (POCIS) were placed in streams near lake inlets and monthly samples …

Occurrence Of Arsenite In Surface And Groundwater Associated With A Perennial Stream Located In Western Nebraska, Usa, Arindam Malakar, Rajesh Singh, Jeffrey Westrop, Karrie A. Weber, Christopher N. Elofson, Manish Kumar, Daniel D. Snow

Nebraska Water Center: Faculty Publications

Dissolved arsenic typically results from chemical weathering of arsenic rich sediments and is most often found in oxidized forms in surface water. The mobility of arsenic is controlled by its valence state and also by its association with iron oxides minerals, the forms of which are both influenced by abiotic and biotic processes in aqueous environment. In this study, speciation methods were used to measure and confirm the presence of reduced arsenic species in the surface water of Frenchman creek, a gaining stream that crosses the Colorado- Nebraska border. Selective extraction analysis of aquifer and stream bed sediments shows that …

Diversification Of Angiosperms During The Cretaceous Period, Sakia Fields

Department of Environmental Studies: Undergraduate Student Theses

The topic of the Angiosperms relatively sudden appearance and diversification is a topic that has puzzled plenty of biologists and is even referred to as an “abominable mystery” by Charles Darwin. Up to date, many hypotheses have been proposed using various forms of data to form them. The available knowledge used to evaluate this topic has changed over the years, which has created some theme shifts. Some of the best supported of these hypotheses are more recent, but this does not make older articles unworthy of being evaluated, as they still often have relevant information. In the past, their appearance …

How Is Remote Sensing Being Used To Prevent Wildfires Today?, Luke Lauby

Department of Environmental Studies: Undergraduate Student Theses

Wildfires frequencies and severities are on the rise. To properly combat and contain them, artificial intelligence should be utilized. An in-depth literature review was conducted in order to evaluate the current state of artificial intelligence specifically relating to wildfire prevention and suppression efforts. The findings in this research sheds further light on the helpful implications that these technologies (both satellites and UAVs) do, and can have on wildfire suppression. If further adopted in wildfire suppression efforts, artificial intelligence can play a more effective role. Through this, fires can become better prevented, more controllable, and better understood using modern technology.

The Effect Of Agkistrodon Contortrix And Crotalus Horridus Venom Toxicity On Strike Locations With Live Prey, Chase Giese

Department of Environmental Studies: Undergraduate Student Theses

This paper aims to uncover if there is a significant difference in the strike location of snake species that have different values of LD50% venom. It is thought that most snakes strike their prey in the anterior (head) area in order for their venom to work quicker in killing them. Venom toxicity is measured by its LD50% value, which is the amount of venom, in mg/kg, to kill 50% of a test population. The Copperhead has an LD50% value of 10.9 mg/kg, and the Timber Rattlesnake has an LD50% value of 1.64 mg/kg. The hypothesis was that if venom toxicity …

Mental Health Incorporation In Nebraskan Recovery Plans Following The 2019 Midwestern Floods, Isabelle Murray

Department of Environmental Studies: Undergraduate Student Theses

In March 2019, Nebraska was hit with major floods that caused extensive damage throughout the state. Nebraskans spent the following months recovering from many aspects of the natural disaster. One aspect of emergency response and the act of recovery that is commonly overlooked is the mental health of individuals following the traumatic events. The purpose of this thesis is to evaluate the level of incorporation of mental health care and services in recovery plans following natural disasters. The qualitative analysis of recovery plans focused on Nebraska and the county-level response to the 2019 Midwestern floods. The objectives were to identify …

Temporal And Spatial Interactions Between Coyotes And Red Foxes Along The Urban–Rural Interface, Adam Mortensen

Department of Environmental Studies: Undergraduate Student Theses

Intraguild competition between predators may cause one predator to alter their temporal activity patterns or occupancy to reduce competition or avoid aggressive encounters. I conducted a temporal activity pattern and occupancy study of coyotes (Canis latrans) and red foxes (Vulpes vulpes) in and around Lincoln, Nebraska using camera traps deployed from September of 2020 to May of 2021. I evaluated the activity patterns of coyotes, red foxes, and humans in urban and rural settings along with the activity patterns of red foxes when sympatric or allopatric with coyotes and determined the coefficient of overlap (Δ) between …

Regenerative Agriculture’S Potential Carbon Storage In Nebraska Soils, Jenna Mccoy

Department of Environmental Studies: Undergraduate Student Theses

This meta-analysis investigates the possible carbon sequestration of no-till and cover crop practices on Nebraska farmlands. These management practices are part of regenerative agriculture, a farming method designed to mitigate and adapt to climate change. As climate change is expected to significantly reduce yields in Nebraska, sequestering carbon in farmlands offers a way to adapt to climate change impacts and lower the concentration of carbon dioxide in the atmosphere. However, changing management practices is difficult and is driven primarily by economics. This study aims to determine how much carbon these practices can sequester in Nebraska soil each year by evaluating …

Effects Of Land Use In Nebraska On Insect Biodiversity And Eastern Monarch Populations, Carina Olivetti

Department of Environmental Studies: Undergraduate Student Theses

How are Nebraska land use decisions affecting eastern monarch butterfly decline? What are the driving factors causing monarch decline? What are the challenges of insect monitoring and data organizing? The purpose of this exploratory research project was to investigate these questions and simultaneously illustrate the importance of insect biodiversity, focusing largely on the monarch butterfly. The eastern population of the monarch butterfly has declined 80% over the past two decades. The state of Nebraska lies within their migratory path and is therefore critical to their survival. The hypothesis is that monarch populations are declining because of the combined impacts of …

Evolution Of Three Streambanks Before And After Stabilization And Record Flooding, Matthew Russell, Aaron R. Mittelstet, Tiffany Messer, Jesse T. Korus, R.M. Joeckel

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Stabilization projects are increasingly used to mitigate the effects of anthropogenic streambank erosion, yet the effectiveness of stabilization has been insufficiently measured. Sound monitoring practices inform adjustments in implementation and maintenance, which improve engineered effectiveness. Thus, the objectives of this study were to: 1) measure streambank migration from in three reaches stabilized with wooden jetties following a major flooding event, and 2) quantify deposition around the jetties between pre-flood and post-flood. Streambank deposition was measured in 2019 with a River Surveyor and Global Positioning System (GPS). Bank erosion rates in Reaches 1, 2 and 3 were 0.41, 0.96 and 0.07 …

A Comprehensive Study To Delineate The Role Of An Extracellular Vesicle-Associated Microrna-29a In Chronic Methamphetamine Use Disorder, Subhash Chand, Austin Gowen, Mason Savine, Dalia Moore, Alexander Clark, Wendy Huynh, Niming Wu, Katherine Odegaard, Lucas Weyrich, Rick A. Bevins, Howard S. Fox, Gurudutt Pendyala, Sowmya V. Yelamanchili

Department of Psychology: Faculty Publications

Extracellular vesicles (EVs), which express a repertoire of cargo molecules (cf. proteins, microRNA, lipids, etc.), have been garnering a prominent role in the modulation of several cellular processes. Here, using both non-human primate and rodent model systems, we provide evidence that brain-derived EV (BDE) miRNA, miR- 29a-3p (mir-29a), is significantly increased during chronic methamphetamine (MA) exposure. Further, miR-29a levels show significant increase both with drug-seeking and reinstatement in a rat MA self-administration model. We also show that EVassociated miR-29a is enriched in EV pool comprising of small EVs and exomeres and further plays a critical role in MA-induced inflammation and …

Much Ado About Missingness: A Demonstration Of Full Information Maximum Likelihood Estimation To Address Missingness In Functional Magnetic Resonance Imaging Data, Timothy D. Nelson, Rebecca L. Brock, Sonja Yokum, Cara C. Tomaso, Cary R. Savage, Eric Stice

Department of Psychology: Faculty Publications

The current paper leveraged a large multi-study functional magnetic resonance imaging (fMRI) dataset (N = 363) and a generated missingness paradigm to demonstrate different approaches for handling missing fMRI data under a variety of conditions. The performance of full information maximum likelihood (FIML) estimation, both with and without auxiliary variables, and listwise deletion were compared under different conditions of generated missing data volumes (i.e., 20, 35, and 50%). FIML generally performed better than listwise deletion in replicating results from the full dataset, but differences were small in the absence of auxiliary variables that correlated strongly with fMRI task data. However, …
