Examining Stable Isotope Variation Of Herbivores In South Luangwa Valley In The Context Of Anthropogenic Influences, Taylor Hubbard

Graduate Theses and Dissertations

Stable isotopes are an effective tool for inferring mammalian behavior. Though there are multiple factors that can influence mammalian diets, anthropogenic influence is one that is often overlooked. For example, it is important to consider how wildlife living in areas where there are frequent, documented human-wildlife interactions will modify behavior. National Parks (NPs) are a great example of this because of the common misconception that since there are protections in place, that means it is devoid of anthropogenic influence. South Luangwa National Park contradicts this misconception. Though there are protections for wildlife in place within the park, it is unfenced …

The Politics Of The Black Womb: How Education And Power Reinforce The U.S. Black Maternal Health Crisis, Foluke Akinkunmi

Honors Scholar Theses

This study investigates the alarming maternal mortality rates among Black women in the U.S. today first by exploring the historical exploitation of Black maternal bodies during enslavement and with the rise of professionalized gynecology. It challenges the narrative that attributes these outcomes to individual choices or supposedly inherent biological factors, arguing instead that the devaluing of Black women’s well-being and authoritative knowledge have been constructed along with the United States itself. To advance a constructive response, the paper analyzes curriculum competencies for obstetric and midwifery healthcare providers, surveys of Black women's birthing experiences in the previous 20 years, and interviews …

Male And Female Contributions To Sexual Dimorphism, Catherine L.W. Clayton

Graduate Theses and Dissertations

Since Darwin, the evolution of sexual dimorphism connects to different evolutionary mechanisms reflecting both natural selection and sexual selection. In primates, body size dimorphism has been attributed to multiple factors, including sexual selection, fecundity selection, ecological selection, and other factors. In contrast, canine tooth size dimorphism has been primarily associated with sexual selection in males with minor change in females, with other factors playing only a secondary role. This suggests that the degree to which body size dimorphism and canine size dimorphism covary, controlling for phylogeny, should reflect the strength of sexual selection. Conversely, the magnitude of divergence between the …

Interobserver Agreement Of Human Osteological Analysis On The Szeged, Hungary Skeletal Collection, Alleyia Bailey

All Theses

Biological anthropologists develop human skeletal biological profiles to identify skeletal remains and build demographic knowledge of past and modern peoples. Biological anthropologists estimate age-at-death, sex, stature, ancestry, and the presence of injury or pathology to develop biological profiles. While biological profiles are at the basis of the work anthropologists perform, there is a lack of research concerning the reproducibility and interobserver agreement rates of the methods used to create biological profiles. Due to the risk of variability stemming from the education, training, and experience of observers, along with variation that can arise from population affinity, examining the interobserver agreement rates …

Primates Shed Light On Glowing Mammals – Adaptation Or Epiphenomenon?, Juliana Hicks

Anthropology

Fluorescence is the ability of chemicals and materials to give off visible or invisible light after absorbing radiation such as ultraviolet light. Fluorescence has been documented in several mammalian families, yet Primates, as an order, have received limited attention in this regard. Within Primates, the suborder Strepsirrhini has been particularly overlooked. Strepsirrhines are compelling subjects due to their retention of primitive mammalian characteristics, representing a significant knowledge gap with respect to the occurrence of fluorescing pelage within the class Mammalia. To address this gap, we investigated the presence and absence of fluorescence in the pelage of preserved museum strepsirrhine specimens …

Accuracy Of Angular Displacement Measurements Using Imu, Aidan Mills

Anthropology

As a part of a larger group, this research focused on gathering data from accelerometers to gather further knowledge on how these devices could be used in further experiments. Using the Sparkfun Artemis accelerometer, angular displacement was isolated and tested to understand the parameters and abilities of the device. Simple tests were run moving the device through 90 degree angular changes. The data collected by the accelerometer was then analyzed using code written specifically to graph angular changes. The data was run through a low and a high pass filter to account for any drift experienced during the tests. An …

Parkinson’S Disease Pathophysiology And Comparative Analysis Of The Efficacy Between Subthalamic Nucleus And Globus Pallidus Interna Deep Brain Stimulation: A Student’S Perspective, Peter C. Solimando Ii

Anthropology

Parkinson’s Disease (PD) is becoming an increasingly common neurodegenerative disease across the world, presenting with both debilitating motor and non-motor symptoms that progressively worsen throughout the course of the disease. Prominent motor symptoms include tremors, bradykinesia, muscle rigidity, and postural/gait instabilities, while common non-motor symptoms include fatigue, pain, autonomic dysfunction (i.e., bowel and bladder dysfunction), mood disorders, and dementia. The advent of modern medical management of PD has introduced several different medications, the most popular being levodopa, that have shown success in reducing the severity of motor symptoms, particularly in the early stages of the disease. Throughout disease progression, however, …

Accuracy Of Balance Assessment Metrics Using Wearable Sensors, Brandon Sirof

Anthropology

Balance is a critical part of remaining healthy at all ages. Poor balance can lead to life-changing injury. Balance is typically assessed in a lab using a force-platform (FP), by comparing horizontal movements of the center of mass during trials with eyes open and eyes closed. The goal of this study is to evaluate whether inertial measurement units (IMUs) can be used to accurately measure balance. Simultaneous FP and IMU data were collected for 1 subject for 45s trials with eyes open (EO) and eyes closed (EC). We evaluate whether IMU and FP metrics for COM movement (max accel and …

Using Wearable Sensors For Gait Analysis: Measurement Accuracy For Linear Measurements, Evan Block

Anthropology

Measurement and analysis of human movement are necessary in a broad range of clinical, sports performance, and artistic applications. Historically, motion data were typically collected using optical motion capture systems. However, these systems are expensive and can only be used in lab spaces, which limits the range and speeds of human behavior. More recently, inexpensive, wearable sensors called Inertial Measurement Units (IMUs) have enabled motion measurement in natural settings, but these systems require validation before use. In this study, we evaluate measurement accuracy for linear displacements obtained using Sparkfun OpenLog Artemis IMUs. We conducted a series of tests, moving the …

Comparison Of Femoral Head Loading In Chimpanzees And Humans, Kyra Kalinovsky

Anthropology

Chimpanzees are the closest living relatives of humans, despite this, the species do have very different loading on the epiphysis of the proximal head of the femur. The difference in loading is primarily due to a difference in locomotion. These differences affect the properties of subchondral and trabecular bone properties in the femoral head. Previous studies have shown that chimpanzees have thick and concave trabeculae that create a dense bone structure (Georgiou et al., 2018). These are found mostly on the inferior and central part of the femoral head. In humans, the structure of the trabecular bone volume is less …

Heat Induced Diagenesis And Osteometrics: An Experimental Approach To Assessing Thermal Alterations To Forensic Anthropological Data On Dry Bone, Audrey Holbeck

Department of Anthropology: Theses and Student Research

Fire appears in forensic casework in instances of arson, vehicle fire, house fire, to conceal evidence, or, in increasing contemporary frequency, wildfire, as a result of climate change. Thermal alteration is a destructive process to osseous material and can impact the accuracy of identification methods and trauma analysis by alteration of the structure, appearance, and morphology of human remains. This study seeks to validate previous research on the metric and morphological changes bone undergoes when exposed to extreme heat, and how that may impede estimation of metric features such as stature. Three long bones, a humerus, femur, and tibia, from …

Comparative Analysis Of Gunshot Trauma And Decomposition In Southeast Nebraska, Alexandra C. Tieken

Department of Anthropology: Theses and Student Research

Accurately identifying gunshot trauma (GST) in forensic anthropology remains a significant challenge, particularly in distinguishing the effects it has on decomposition. This study investigates how different types of gunshot trauma influence the rate and characteristics of decomposition in a humid continental climate, specifically southeastern Nebraska. Utilizing Sus scrofa domesticus (domestic pigs) as human proxies, four pigs were euthanized by professionals and subjected to controlled conditions at the Reller Prairie Field Station. Three pigs were inflicted postmortem with close-range gunshot trauma using a 9mm handgun, a 12-gauge shotgun, and an AR-15 rifle, while a fourth served as a trauma-free control. For …

Firearm Trauma Across Time: Investigating Civil War Gunshot Trauma And Their Impact On Modern Forensic Analysis, Morgan K. Reeder

Department of Anthropology: Theses and Student Research

This thesis will examine the ballistic trauma caused by Civil War-era firearms and ammunition. These weapons, each with distinct characteristics, had a profound impact on the nature of combat and the resulting injuries. By investigating how these firearms’ ammunition interacted with human bone structure, this research will offer a detailed analysis of the trauma these weapons produced.

This research intends to answer several key research questions. First, how did the different types of Civil War firearms affect skeletal remains? Second, what are the key characteristics of gunshot trauma caused by these firearms in terms of bone fracturing and fragmentation, and …

Wildfire And Decomposition: A Taphonomic Analysis Of Thermal Alterations And Decomposition, Ashley Novak

Department of Anthropology: Theses and Student Research

Within the field of forensic anthropology, practitioners may be faced with remains that have been thermally altered by thermal alterations caused by wildfire. Within the field, very little research has been conducted examining how these thermal events impact rates of decomposition. While research has been conducted generally on the effects of thermal alteration on decomposition, these studies do not look through this lens and provide answers to the question of how do thermal alterations caused by wildfires affect rates of decomposition? This research examines the effects of thermal alteration caused by wildfire on the rate of decomposition. A decompositional study …

Trends In Dna Aanalysis To Determine Postmortem Interval: A Systematic Lilterature Review, Victoria S. Kashkin

Department of Anthropology: Theses and Student Research

Forensic taphonomy is a recently popular field within forensic anthropology with limited research in the Central Great Plains. Given decomposition varies by region, more studies must be done to understand aspects of decomposition in this region. However, it is one of the most important subfields of forensic anthropology since determining postmortem interval (PMI) is extremely important to successfully identifying a missing individual if other indications of who the individual is are nonexistent. In this study, a systematic literature review was conducted to answer what trends are seen in research being done for using DNA to determine PMI, and what methods …

Who Was Skull #0025336? A Forensic Anthropological Analysis Of Human Remains, Evelyn R. Wendland

Undergraduate Honors Theses

Biological anthropology identifies human remains to learn more about the individual or the ancient community from which they originate. Two subdisciplines of biological Anthropology that focus on osteology—the study of bones— are Forensic Anthropology and Biorchaeology. Forensic anthropology is the study of human remains associated with the legal process. They specifically analyze remains from post-1950. Biorchaeology also looks at human remains but in a historical and/or archaeological context. As osteologists analyze human remains, they typically try to create a biological profile. The biological profile includes classifications of ethnicity (ancestry), age, sex, and stature, as well as aspects of pathology and …

Sex Differences In Adult Frailty At The Late-Terminal Classic (C. 750-1000 Ce) Maya Site Of Lower Dover, Rose Rioux

Honors Thesis

While it has been suggested that the compounded effects of population growth and climatic pressures over the Classic period (c. 300-1000 CE) led to a health crisis among the Maya, there is no current knowledge of whether there were significant sex differences in risks of mortality and frailty associated with metabolic stressors. This research assesses sex differences in frailty and mortality of adults (n=52) from the medium-sized Maya polity of Lower Dover in the upper Belize River Valley from the Late Preclassic (c. 300 BCE-150 CE) to Terminal Classic (c. 750-1000 CE). Osteological methods of estimating age and sex were …

A nearly complete female skull is the holotype of Dolichopithecus arvernensis Depéret, 1928, now included in Paradolichopithecus. Emended and differential diagnoses are provided for this genus and species for the first time, and the Senèze skull is described and briefly compared to those of other species of the genus. Dental and cranial measurements are provided, along with comparative data. The macaque and Paradolichopithecus are moderately to highly terrestrial, respectively, and they suggest a woodland to more open …

Characterizing The Nutrition-Gut Microbiome-Host Physiology Axis To Examine Flexibility In A Fruit-Specialist Primate, Nina Beeby

Dissertations, Theses, and Capstone Projects

Nutrition and, increasingly, microbiota are recognized in shaping all aspects of animal behavioral ecology and physiology. Since diet and nutrition shape not only animal physiology but also gut microbiota, and these microbiota serve as suppliers of and competitors to host nutrition, this raises questions of how these complex nutritional and microbial environments synergistically affect animal physiology. Examining this nutrition-gut microbiome-host physiology axis has immense potential to unveil how these intricate relationships contribute to animals’ responses to environmental change at multiple scales. Most of what we know about primate responses to environmental change is based upon studies examining one or few …

Pass It Along: Learning About Health Inequities Through Project-Based Learning And A Student-Developed Workshop, Marcy S. Ekanayake-Weber, Deanna Cunha, Kristi L. Fung, Sydney Macgregor, Nicole Ribeiro, Nicholas Smith

International Journal of Transformative Teaching and Learning in Higher Education

People in marginalized communities experience reduced quality of healthcare due to complex interactions between implicit bias, stereotypes, and structural inequities, but future healthcare providers remain unprepared to confront these problems. To address the issue of health inequities in health sciences education, a project-based learning seminar for undergraduates called “Biology of Inequity” was developed and offered by the Department of Anthropology at [redacted] University in Spring semester 2022. Following the project-based learning (PBL) framework, the course was extremely interactive, culminating in a project where students were asked to “materially improve health inequalities out in the real world.” The students responded by …

Reassessing The Role Of Polynesian Rats (Rattus Exulans) In Rapa Nui (Easter Island) Deforestation: Faunal Evidence And Ecological Modeling, Terry L. Hunt, Carl P. Lipo

Anthropology Datasets

The role of introduced Polynesian rats (Rattus exulans) in the deforestation of Rapa Nui remains a contentious issue. Several critics, including Mieth and Bork (2010), argue that rats played a negligible role compared to human impacts. We address the role of rats through three lines of evidence: (1) a response to rats-are-neglible arguments, including problematic continental analogies and misunderstandings of seed predation impacts; (2) analysis of rat remains from Anakena excavations (1986-2005) showing that rats decreased by 93% over time, contradicting claims they served as a “fallback food” following resource depletion; and (3) ecological modeling demonstrating that introduced …

Review Of Digging For The Disappeared: Forensic Science After Atrocity, Abigail Vaughn

Nebraska Anthropologist

Since the field's development, individuals and communities involved in and affected by international forensic investigations have been confronted with many political and ethical dilemmas. The book, Digging for the Disappeared: Forensic Science After Atrocity (2015), by Adam Rosenblatt, attempts to identify and articulate the various debates surrounding humanitarian forensic work. In doing so, the author focuses on four key areas; the purpose of such investigations, the stakeholders and expectations involved, and what may realistically be accomplished. While sympathetic to the perspective of forensic practitioners, Rosenblatt presents the positions of all parties in an unbiased manner, introducing the reader to …

A Critical Approach To Analyzing And Addressing Worldview-Based Cultural Conflict Between Indigenous Peoples And Western Science In Education And Research, Deborah H. Williams

Sabbatical Projects

Intercultural conflict exists in science education and research, I argue as a result of differences between the Western scientific worldview and the Indigenous worldview. Native Americans are the most underrepresented group in STEM, and this has been the case, in my personal experience for over two decades. Western science is not universal or acultural, Indigenous peoples have their own ways of knowing founded on different philosophical assumptions and recognizing metaphysical phenomena and explanations that are rejected by Western science and the positivist/post-positivist paradigm. Through the power of colonial privilege, scientists, science departments, and science disciplines have been able to erect …

Investigating The Impact Of Phthalate Exposures From Personal Care Products On Uterine Fibroid Incidence And Prevalence In Us-Born Black Women, Ella Brissett

CMC Senior Theses

Uterine fibroids are benign tumors composed of smooth muscle cells and connective tissue that develop within or on the walls of the uterus. Despite being non-cancerous, they can severely affect quality of life by causing heavy bleeding, chronic pain, and reproductive complications. Fibroids are typically found in women of reproductive age, but they disproportionately affect Black women, who experience higher incidence and severity. The underlying causes of this disparity is poorly understood; however, an emerging body of research is highlighting the role of phthalates, endocrine-disrupting chemicals found in many personal care products, in exacerbating fibroid development. Through a critical analysis …

Fire History, Ecological History, And Historical Human-Environment Interactions In The Northern Great Plains, James Victor Benes

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

This dissertation explores the spatiotemporal signatures of fire in North American grassland ecosystems. In three chapters, I explore different aspects of fire history in the northern Great Plains. Chapter 1 is an introduction. Chapter 2 focuses on the Euro-American Settlement Period (ca. 1850–1950 C.E.). Fire histories from six different lakes in the Nebraska Sandhills are compared with two periods of historic drought and the establishment of United States Post Offices. Five of the six records show increased levels of biomass burning during the initial phases of Euro-American Settlement. Chapter 3 is a long-term (ca. 15,000 years), high-resolution fire history and …

Establishing Metric Method’S To Identify Variation In Human Biological Sex Using The Upper And Lower Limb Bones Of Non-Population Specific Samples., Roland P. Sanchez

Graduate Student Theses, Dissertations, & Professional Papers

Sex estimation of human skeletal remains is a facet of the biological profile. The pelvis has been suggested as the best source to accurately predicting the biological sex, but not always available after the recovery of human remains. At times, only long bones of human skeletal remains are recovered for identification. It has been shown that metric measurements using long can accurately predict biological sex. The most common methods use discriminant functions to predict the likelihood an individual falls within a certain population. These studies rely on population specific collections of skeletal remains for increased accuracy. It’s advised to avoid …

Hormonal Decay After Death: Evaluating Dhea-S As A Potential Molecular Marker For Postmortem Estimation, Marisa Lydia Novak

Graduate Student Theses, Dissertations, & Professional Papers

Post-mortem interval (PMI) estimation is a central component of forensic anthropological investigation, but traditional methods for estimating time since death lose accuracy after ~72 hours. Recent research indicates that some steroid hormones may undergo predictable degradation patterns after death, offering potential use as biochemical clocks for PMI estimation beyond this threshold. Dehydroepiandrosterone (DHEA), and its sulfate form (DHEA-S) are of particular interest due to their metabolic stability, systemic influence, and association with trauma. This study investigates whether DHEA-S hormonal degradation patterns correlate with time elapsed since death and body temperature, evaluating their potential as biochemical PMI markers. 160 mL of …
