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 …

Geophysics, And Capturing Ethnographic Interviews Of A Tidal Plantation Burial Ground, Kristin M. Meeuwen (Dew)

College of Graduate Studies: Theses & Dissertations

Plantation development in Chatham County has a rich but incomplete history. Silk Hope, an Ogeechee District tidal plantation, is located seven miles from the city of Savannah on the Northern banks of the Little Ogeechee River. This project focuses on identifying the site boundaries of portions of Silk Hope Plantation and its historical background. Specifically, the project focused on delineating the boundaries of the associated cemetery and/or burial grounds, while estimating the number of individuals interred there using ground-penetrating radar (GPR). Finally, collaborative work with community members, including stakeholder and descendant interviews, will provide ethnographic insights into the site's history …

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 …

Should Human Remains Be On Display In Museums?, Erik Schulz

Nebraska Anthropologist

The debate of should human remains be displayed in museums, exhibits, classrooms, and other public areas has been a topic of discussion in recent years. This article aims to explore the positives and negatives of displaying remains through scientific racism, decolonization, ethics, and forensic anthropology. Although these characteristics may not always be present in a collection, they are common concerns, and they are also not the only concerns for displaying remains. The objective of examining this issue from multiple perspectives is to propose viable solutions for the ethical and appropriate display of human remains. This research will be geared more …

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 …

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 …

Comparative Semiotic Analysis Of Non-Verbal Communication: Apis Mellifera Waggle Dance And Human Kinesic Signaling Systems, Nishtha Tikalal

Honors Undergraduate Theses

There are many parallels between two seemingly disparate forms of non-verbal communication: the waggle dance of Apis mellifera (honeybees) and human kinesic signaling systems. Through a comparative semiotic analysis, this research aims to conduct a comparative semiotic analysis, investigating structural and functional similarities between these communication methods, challenging anthropocentric assumptions about meaning making in the natural world. This research employs a meta-synthesis approach, drawn from a methodological literature review to examine historical representations of bee-human relationships, semiotics of non-verbal communication, and the specific mechanisms of the waggle dance and human kinesics. This methodology involves systematic categorization and analysis of extracted …

Tools And Trends: An Analysis Of Maya Dental Modification, Channing M. Cook

Honors Undergraduate Theses

The ancient Maya practiced dental modification, intentionally filing, incising, and inlaying stones into the front teeth, potentially to display identity and status. The literature surrounding Maya dental modification tends to overlook mechanical aspects of the process, and many studies approach dental modification through limiting or destructive means. Optical microscopy presents an adaptable, cost-effective option for closer inquiry. Preliminary research suggests the process of dental modification leaves distinct patterns of tool use, depending on style, that can be identified through optical microscopy. The sample selected includes 25 incisors and canines from 14 Classic period Maya individuals from Altun Ha, representing 12 …

Role Of C4 Resources In Isotopic Variability In Diet Among Children From Kellis 2 Cemetery, Dakhleh Oasis, Egypt, Faith R. Hendrix

Honors Undergraduate Theses

Using stable carbon isotope analysis, this study investigates dietary diversity in children buried at the Kellis 2 Cemetery (c. AD 50–450) in Egypt's Dakhleh Oasis. From the analysis of δ¹³C isotope values in hair keratin and bone collagen, the study reconstructs short-term and long-term dietary signals in juvenile and adult subjects. The aim is to clarify the role of C₄ plants—particularly millet—in weaning and childhood diets in a Romano-Christian Egyptian village context. A total of 631 segmented hair and 54 bone collagen samples were analyzed from 127 juveniles and 97 adults. Juvenile individuals (i.e., under 15 years biological age) showed …

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 …

On Creating Bog Bodies: The Effects Of Ph Value On Dna Decomposition In A Bog Environment, Gabrielle B. Giangreco

Graduate Student Theses, Dissertations, & Professional Papers

Bog bodies have been a consistent area of interest in both archaeology and biological anthropology, due to their high rates of physical preservation. While there are many physical analyses that have been done on these remains, DNA analysis is lacking. Most studies focus on changes to the remains themselves or attempt to determine why they were placed in a bog. This study aims to examine the effects of pH level on the breakdown of DNA on remains placed inside a bog along with any larger differences in the preservation of the remains. The results of this study seem to point …

Learning Through Following: The Role Of Social Foraging In Juvenile Saddleback Tamarin (Leontocebus Weddelli Weddelli) Development In The Department Of Pando, Bolivia, Meghan E.F. Hanson

Graduate Research Theses & Dissertations

Across the primate order, the juvenile stage is an important period of development that transitions individuals from infancy to adulthood. During the juvenile stage, individuals are weaned but lack experience feeding and foraging on solid foods. As a result, juveniles must learn foraging and feeding skills during this vital period of growth and development. The purpose of this study is to assess how juvenile saddleback tamarins (Leontocebus weddelli) gain foraging and food manipulation skills. During this study, I observed feeding behaviors in a group containing two juveniles and four adults, located at the Estación Biológica Tahuamanu in the Department of …

Insect Foraging Behaviors Across Habitat Types In Weddell’S Saddle-Back Tamarins, (Leontocebus Weddelli Weddelli) In Pando, Bolivia, Brianna Nicole Abba

Graduate Research Theses & Dissertations

Researchers assume that small-bodied primates like the callitrichines are highly adaptable to environmental change and can increase their consumption of insects in disturbed habitats, however, these assumptions have rarely been tested. To better understand how habitat and other factors may influence the frequency of insect foraging, the type of prey capture techniques used, and prey capture success, I collected detailed observational data on one group of Weddell’s saddle-back tamarins (Leontocebus weddelli weddelli) in northwestern Bolivia in July and August 2022. I found that tamarins spent 62% of their total foraging and feeding time on insects. They spent 89% of their …

Evaluating The Accuracy Of Stature Estimation From Tibial Radiographs Using Known And Newly Developed Regression Formulas, Atlantis Kae Baron

Graduate Student Theses, Dissertations, & Professional Papers

This study assesses the accuracy of stature estimation from tibial radiographs using digital measurements as an alternative to traditional osteometric tools. Stature estimation is crucial in forensic anthropology for identifying individuals, especially cases involving skeletal remains. Traditional methods rely on physical measurements and established regression formulas, such as those by Trotter & Gleser (1958).

This research analyzed tibial radiographs from the Forensic Anthropology Skeletal Trauma (FAST) database with ImageJ software to measure tibial lengths digitally. The sample included 59 tibiae, with measurements compared against three regression formulas; Trotter & Gleser (1958), Simon et al. (2023), and a new regression formula …

Comparative Bioinformatic Methodologies In Paleogenetic Pathogen Identification In The Casas Grandes, Victoria Lynne Giovannangelo

Graduate Student Theses, Dissertations, & Professional Papers

The application of metagenomic tools to further elucidate ancient DNA (aDNA) holds promise in paleopathology, particularly for inferring disease patterns in ancient populations, especially in those that are understudied. This study conducts a comparative analysis of the efficacy of taxonomic pipelines--Kraken 2, HOPS/MALT, and HAYSTAC--in detecting pathogens within highly degraded aDNA samples extracted from 22 Medio Period Paquimé individuals from the Casas Grandes archaeological site in Northwest Mexico. The taxonomic results from the pipelines are compared with contamination detection program mapDamage, although concerns arose about the latter program’s ability to work with prokaryotes. Additionally, the findings are compared against prior …
