The Impacts Of Environment And Host Evolutionary Relationships On Lemur Microbiota, Rachel B. Burten

Doctoral Dissertations

Recent studies have shown that the mammal microbiome is modified by environmental conditions, and that reduced microbiome functionality is associated with host health issues. Microbiome data in wild and captive primate populations can therefore be used to assess their health as they encounter a variety of environments. Comparative studies of the microbiome can also inform disease ecology, conservation, and captive management strategies tailored to different primate species. Therefore, this study examines how the hair, oral, and gut microbiota of nine wild and captive lemur species are determined by host phylogenetic relationships and host environment. I found that host species identity …

Sociocultural And Familial Factors Associated With Symptom Experience At Midlife Among Women In Nagaland, India, Peteneinuo Rulu

Doctoral Dissertations

This cross-sectional study examines the sociocultural and familial factors that are associated with symptom experience at midlife among women in Nagaland. More specifically, the study examines the factors associated with symptoms at midlife, the relationship between symptoms at midlife, household stressors, ethnopolitical problems, and various measures of stress, and the buffering effects of social support against the negative effects of stress on symptoms at midlife. Data from 151 women aged 40-55 were collected from 4 regions in Nagaland, India. The most common symptoms reported during the past two weeks were headaches (72%), tiredness or lack of energy (67.5%), and hot …

Intra-Skeletal Variation In Stable Isotopes Through Non-Destructive Approaches: Applications Of The Patterns Of Skeletal Remodeling To Biological Anthropology, Armando Anzellini

Doctoral Dissertations

Stable isotope analysis is a well-established method in biological anthropology used to deliver data on residence, diet, and life history. Samples for these analyses are often collected from the diaphyses of long bones with an assumption of an expected rate of turnover between five and ten years, depending on the skeletal element. However, the biological foundations of this assumption are still uncertain, especially concerning the intra-skeletal and intra-element variation of isotopic signatures that may relate to patterns of remodeling. Exploring these gaps in intra-element isotopic variation requires fine-grained work using multiple bones from multiple individuals, but such work is limited …

Morbidity, Mortality, And Marginalization: An Intersectional Investigation Of Respiratory Stress And Differential Frailty In Industrial-Era England, Derek A. Boyd

Doctoral Dissertations

Respiratory disease affects more than one billion people today, particularly in urbanizing areas of low- and middle-income countries due to overcrowding, air pollution, poor sanitation, and differential access to life-sustaining resources. We can look to the past to understand the social, economic, and environmental factors that influence respiratory disease burden among urban dwellers because conditions in the urbanizing areas of antiquity mimic those observed in lower- and middle-income countries today. This study explored the impact of classism, sexism, and regional inequalities on respiratory disease burden among urban dwellers with differing levels of social and economic marginalization in England during the …

Sphenoidal Sinuses And Spherical Harmonics: Variation And Covariation Of The Most Morphologically Diverse And Least Understood Paranasal Sinus, Katharine Grace Josephine Ryan

Doctoral Dissertations

Understanding the shape variation of the human sphenoidal sinus is important to several areas of research. This includes clinical investigation (sinus pathology and safe endoscopic endonasal surgical practice) and paranasal sinus evolution (for which there is still no consensus). Yet, the sphenoidal sinus has high morphological variation, prohibiting its quantification through traditional geometric morphometric landmarking methods. The sphenoid body, and thus also the sinus contained within, is located directly at the developmental center of the basicranium in humans, where the three cranial fossae meet at the midline, and adjacent to the three synchondroses which are the sites of cranial base …

Assessing Multiple Lines Of Evidence For Gene Flow In Archaeological Contexts, Angela Marie Mallard

Doctoral Dissertations

This multi-study dissertation assesses the ability of two skeletal analysis methods—a model-bound quantitative genetic method (Relethford-Blangero) and a model-free biological distance method (Mahalanobis’ D²)—to evaluate gene flow in the U.S. Southwest and Northwest Mexico based on archaeological models. The first study uses dental metric data from the Sonoran Desert and Mogollon Rim (c. 1600 B.C. to A.D. 1450) to pilot the Relethford-Blangero method in this context. Notably, the method shows that populations from two large sites have less than expected dental variance, failing to support a gene flow event despite material culture pointing to at least two coexisting …

Diversity And Evolution Of Human Eccrine Sweat Gland Density, Andrew W. Best

Doctoral Dissertations

Human eccrine density is highly derived. However, little is known about contemporary variation in this trait, what shapes it, and how it influences heat dissipation. This project explores 3 questions: 1) Is variation in functional eccrine density (FED) explained by childhood climate? 2) Is this variation patterned by geographic ancestry? 3) Is variation in FED associated with differences in heat dissipation capacity? We measured FED and sweat production in 6 body areas via pharmacological stimulation and impressions of sweating skin in 72 participants. Childhood climate variables were taken from the WorldClim database and geographic ancestry was estimated with 23andMe tests. …

De-Coding The Impact Of Evolved Changes In Gene Expression And Cellular Phenotype On Primate Evolution, Trisha Zintel

Doctoral Dissertations

The goal of the dissertation work outlined here was to investigate the influence of proximal processes contributing to evolutionary differences in phenotypes among primate species. There are numerous previous comparative analyses of gene expression between primate brain regions. However, primate brain tissue samples are relatively rare, and my results have contributed to the pre-existing data on more well-studied primates (i.e. humans, chimpanzees, macaques, marmosets) as well as produced information on more rarely-studied primates (i.e. patas monkey, siamang, spider monkey). Additionally, the primary visual cortex has not previously been as extensively studied at the level of gene expression as other brain …

Variation In Cortical Bone Distribution In The Aging Adult Appendicular Skeleton, Alice Fazlollah Gooding

Doctoral Dissertations

This study considers the effects of age on the distribution of bone in the adult skeleton. Age effects on the skeleton have been studied for diagnosis of osteoporosis or as mechanical compensatory changes to bone shape with loss in density. However, adult skeletal morphology is the result of a lifetime of genetic, dietary, activity, and biochemical factors. With these influences, it unclear at what age(s) bone geometry shifts to adapt to the physiological and mechanical demands placed on it, or, how these adaptations vary within and between bones.

This research addresses these questions by examining skeletal data obtained from the …

Who Ate The Subfossil Lemurs? A Taphonomic And Community Study Of Raptor, Crocodylian And Carnivoran Predation Of The Extinct Quaternary Lemurs Of Madagascar., Lindsay Meador

Doctoral Dissertations

Madagascar’s Quaternary predator-primate guild included seventeen species of relatively large extinct lemurs. Sharing the landscape with the lemurs, were several relatively large now-extinct predators, including three raptors (two species of Aquila and Stephanoaetus mahery), a euplerid (Cryptoprocta spelea), and a crocodile (Voay robustus). This is the first research to systematically study predator-prey relationships among these extinct animals. Here I examine the bones of the extinct lemurs at six subfossil localities (Ampasambazimba, Ankarana, Grotte d’Ankazoabo, Beloha Anavoha, Manombo Toliara, and Tsirave) for evidence of and also collected metric data on these bones. I examined 1141 specimens …

An Exploration Of The Effects Of Taphonomy On Isotope Ratios Of Human Hair, Tiffany Bivens Saul

Doctoral Dissertations

Isotope analyses of human remains have been conducted with growing frequency over the past thirty years in anthropology, in both archaeological and forensic contexts. Analyses of isotope ratios of elements such as carbon, nitrogen, hydrogen, oxygen, and strontium from teeth, bones, and hair have provided information regarding individual diet and geographic movement during different life stages. Hair grows at a predictable rate and provides a serial recording of diet and travel history for the weeks and months just prior to death. What has not been systematically studied is whether postmortem decompositional changes to the body have an effect upon isotope …

The Effects Of Racialization On European American Stress In The Nineteenth And Twentieth Centuries, Kimberly T. Wren

Doctoral Dissertations

This dissertation explores disparities in stress among European Americans (EA) and between EA and African Americans (AA) in racialized communities in the nineteenth and twentieth centuries. Comparisons among EA and between EA and AA are conducted to understand the biological consequences of racialization. Racialization is the process of assigning people to hierarchical categories for purposes of political, social, and economic discrimination. This dissertation investigates how racialization might have affected childhood stress using biocultural theory and facets of critical archaeology theory. Indicators of stress from skeletonized individuals in the William M. Bass Donated Skeletal Collection, Hamann-Todd Osteological Collection, and the Robert …

The Effects Of Industrialization And Urbanization On Growth And Development: A Comparison Of Boys And Girls From Three Industrial European Skeletal Collections, Sarah Reedy

Doctoral Dissertations

Exposure to poor environments, malnutrition, and labor during childhood can lead to stunted height and increased mortality. Studies of skeletal samples from Industrial Era Europe show height is stunted when compared to Medieval samples, suggesting harsher conditions. While poor conditions can negatively impact all children, boys may be particularly disadvantaged, because girls can reserve nutritional components buffering them during times of stress. This study examines the environmental effects on growth in three Industrial European skeletal samples. Juveniles (0-18 years) from varied SES backgrounds were used to test three hypotheses. H1) Industrial Era children will exhibit shorter femora relative to a …

Can Long Bone Structural Variability Detect Among-Population Relationships?, Gina Agostini

Doctoral Dissertations

Phenotypic traits develop and are maintained by complex interactions between intrinsic (molecular) and extrinsic (environmental) factors. While the influence of intrinsic factors on adult craniomandibular variation has been intensively studied, less is known about limb bones, in part because it is assumed that their plasticity obscures intrinsic signals, especially those fixed early in life. While diaphyseal regions are plastic in response to activity, the extent to which they also reflect (phylo)genetic autocorrelation has not been sufficiently addressed, particularly given the common practice of comparing long bones across populations unevenly dispersed in space and time. Here I investigate the degree to …

A Characterization Of Human Burial Signatures Using Spectroscopy And Lidar, Katie Ann Corcoran

Doctoral Dissertations

This study is an analysis of terrestrial remote sensing data sets collected at the University of Tennessee’s Anthropology Research Facility (ARF). The objective is to characterize human burial signatures using spectroscopy and laser scanning technologies. The development of remote human burial detection methodologies depends on basic research to establish signatures that inform forensic investigations. This dissertation provides recommendations for future research on remote sensing of human burials, and for investigators who wish to apply these technologies to case work.

Data used in this study include terrestrial spectra, aerial hyperspectral imagery, satellite multispectral imagery, terrestrial light detection and ranging (LIDAR), and …

Understanding Population-Specific Age Estimation Using Multivariate Cumulative Probit Regression For Asian Skeletal Samples, Ji Eun Kim

Doctoral Dissertations

For many years, the field of anthropology has encouraged anthropologists to assume that population variation exists in skeletal aging although interpretations of population specificity in skeletal aging have been inconsistent. This project investigates age progressive changes in modern East and Southeast Asian populations, and attempts to quantify the magnitude of differences or similarities in skeletal aging between different Asian groups as a first step to develop a more inclusive age estimation method for Asian populations. Specifically, this study explores the utility of currently available age estimation methods for Asian populations, asks whether a population-specific aging method should be region-specific (Thai …

Modeling Prehistoric Health In The Middle Cumberland Region Of Tennessee: Mississippian Populations On The Threshold Of Collapse, Christina Laiz Fojas

Doctoral Dissertations

This research explores differences in mortality and survivorship resulting from factors associated with the abandonment of the Middle Cumberland Region (MCR) of Tennessee during the Mississippian period (ca. 1000-1500 AD). My dissertation investigates whether individuals from the Late Mississippian period had a greater risk of death than individuals from the Early Mississippian period. Adult age-at-death estimates (n=545) were calculated using Transition Analysis, a Bayesian maximum likelihood method. Gompertz and Gompertz-Makeham hazard models were utilized to reconstruct the mortality profile of the MCR as they model human adult mortality and generate robust parametric mortality profiles. Rather than recount the prevalence of …

The Evaluation And Refinement Of Nonmetric Sex And Ancestry Assessment Methods In Modern Japanese And Thai Individuals, Sean D. Tallman

Doctoral Dissertations

Effective biological profiles in forensic anthropology and bioarchaeology depend on the development, validation, and refinement of population-specific methods. However, most methods were developed in North America on individuals of African and European descent, and it is unlikely that such methods can generate accurate biological profiles for Asian individuals. Moreover, Native Americans have served as biological proxies for Asians due to their distantly shared genetic history, resulting in largely untested assumptions that Native Americans and Asians are homogenous and share nonmetric sexually dimorphic skeletal features and a unique suite of cranial traits that can be used in ancestry assessment.

This study …

Evaluating Differential Nuclear Dna Yield Rates Among Human Bone Tissue Types: A Synchrotron Micro-Ct Approach, Janna Michelle Andronowski

Doctoral Dissertations

Molecular human identification has conventionally focused on DNA sampling from dense, weight-bearing cortical bone tissue from femora or tibiae. A comparison of skeletal elements from three contemporary individuals demonstrated that elements with high quantities of cancellous bone yielded nuclear DNA at the highest rates, suggesting that preferentially sampling cortical bone is suboptimal (Mundorff & Davoren, 2014). Despite these findings, the reason for the differential DNA yields between cortical and cancellous bone tissues remains unknown.

The primary goal of this research is to ascertain whether differences in bone microstructure can be used to explain differential nuclear DNA yield among bone tissue …

The Effect Of Social And Environmental Stresses Among The Historic Arikara Native Americans, Jocelyn Diana Minsky-Rowland

Doctoral Dissertations

The Arikara Native Americans from the Anton Rygh, Mobridge, Larson and Leavenworth sites, inhabited the Great Plains of western North America (AD 1600-1832). The Arikara experienced climatic changes, warfare, interactions with novel groups of people and disease epidemics and therefore represent an opportunity to assess differential risk of death in a stressful context. The overarching question of this project is, in the historic context of environmental and social stresses, do these environmental and social stresses (as indicated by specific skeletal markers that occur during childhood) increase the risk of death from later infectious disease or warfare related trauma experienced in …

An Analysis Of Skeletal Trauma Patterning Of Accidental And Intentional Injury, Shauna Lynn Mcnulty

Doctoral Dissertations

The ability to determine the cause of skeletal trauma – i.e. an injury produced by blunt, sharp, or ballistic forces - is critical in assessing the manner of death. The purpose of this study is to examine the patterns of injury between known accidental and intentional trauma cases while considering demographics, fracture features, and the location of injuries in individuals of varying ages, sexes, and ancestries. The current literature has identified a pattern for intentional injuries that is focused on the head, neck, and face, while accidental trauma tends to be more dispersed throughout the skeleton with more injuries found …

A Quantitative Genetic Analysis Of Limb Segment Morphology In Humans And Other Primates: Genetic Variance, Morphological Integration, And Linkage Analysis, Brannon Irene Hulsey

Doctoral Dissertations

Limb segment lengths (and, by extension, limb proportions) are widely studied postcranial features in biological anthropology due to the seemingly consistent phenotypic patterning among human and fossil hominin groups. This patterning, widely presumed to be the result of adaptation to thermoregulatory efficiency, has led to the assumption among biological anthropologists that limb proportions in humans are phenotypically stable unless long periods of extreme environmental conditions force adaptive change. Because these traits are considered stable, they have been used to inform multiple areas of anthropological inquiry, including investigations of phylogenetic relationships and fossil species identification, locomotor behavior and the evolution of …

A Biologically Informed Structure To Accuracy In Osteometric Reassociation, Kyle Mccormick

Doctoral Dissertations

Commingled assemblages present a common situation in osteological analysis where discrete sets of remains are not readily apparent, thereby hindering biological profile construction and the identification process. Of the methods available for resolving commingling, osteometric reassociation is considered a reliable and relatively objective technique. Traditional osteometric sorting methodologies is a decision-making, error-mitigation approach, where possible matches are eliminated if the calculated pvalue exceeds an analyst-defined threshold. This approach implicitly assumes that all bone comparisons are equally accurate as long as the threshold is attained. This assumption, however, is not based in biological reality. This study tests a hypothetical structure of …

Investigating Cranial Variation In Japanese Populations Using Geometric Morphometrics, Beatrix Dudzik

Doctoral Dissertations

The Japanese archipelago exhibits an immense amount of variation in culture and history, despite the lay population mostly considering the modern Japanese a homogeneous population. Japan has experienced an amazing amount migration activity. These migration events are well represented in the archaeological record and have provided fodder for hypotheses proposed for peopling of the new world.

Biological anthropologists have tested hypotheses surrounding the initial peopling of the islands using linear data in conjunction with non-metric traits of the skull. Recent molecular studies have provided evidence for population substructure, which suggests an original founding group of North Asian descent, and a …

Is Quantitative Ultrasound A Valid Technique For Assessing Bone Quality In Deceased Infants?, Miriam Elizabeth Soto Martinez

Doctoral Dissertations

There is no quantitative method for evaluating infant bone quality that is non-invasive, portable, brief in scan duration, and does not use ionizing radiation. This study investigates the relationship between components of infant bone quality and a measure of quantitative ultrasound (QUS), speed of sound (SOS), to provide insight into the validity of QUS as a diagnostic tool for evaluating infant bone quality. The study sample was comprised of 78 infants between the age of 30 weeks estimated gestational age and 12 postnatal months receiving an autopsy at the Harris County Institute of Forensic Sciences and Texas Children’s Hospital. Bone …

Illegal Hunting On The Masoala Peninsula Of Madagascar: Its Extent, Causes, And Impact On Lemurs And Humans, Cortni Borgerson

Doctoral Dissertations

Two of the greatest challenges we face in the world today are: (1) reducing human poverty and malnutrition; and (2) slowing the loss of global biodiversity. Madagascar ranks nearly last in global food security, and is one of the most biodiverse countries in the world. Within Madagascar, the Masoala Peninsula is one of our greatest conservation priorities. I use one year (July 2011 – June 2012) of lemur surveys, habitat sampling, direct observations of forest mammal hunting, eleven months of daily 24-hour recall surveys, and interviews of all households in one focal village on the Masoala peninsula of Madagascar to …

Age Estimation With Decision Trees: Testing The Relevance Of 94 Aging Indicators On The William M. Bass Donated Collection, Kevin Benjamin Dominic Hufnagl

Doctoral Dissertations

Anthropologists have been estimating ages-at-death of skeletons for a long time. A variety of different age indicators has been studied and age estimation methods have been developed in an attempt to standardize the process. Even with all the work that has gone into developing age estimation methods, age estimation of mature skeletons is still very imprecise. This research investigates various age indicator definitions and their performance on an elderly skeletal sample. Using 176 individuals from the William M. Bass Donated Collection curated in the Department of Anthropology at the University of Tennessee, Knoxville, data were collected on age indicators gathered …

Investigating Postnatal Ontogeny In The Craniofacial Complex Of Human Juveniles, Amber Davis Wheat

Doctoral Dissertations

Researchers have analyzed the developmental processes contributing to craniofacial variation from genetic, evolutionary, biomechanical and forensic perspectives, yet no study has clearly demonstrated the exact anatomical processes that occur in the craniofacial complex during postnatal growth to establish ultimate adult morphologies. Furthermore, previous research has not evaluated how endocranial bones (i.e., the ethmoid and sphenoid) play a role in postnatal craniofacial growth. Thus, while researchers have hypothesized that the long postnatal period of continued growth contributes to the high amount of variation observed in adult facial variation, this has yet to be shown empirically.

The presented research uses cranial data …

Studies In Taphonomy: Bone And Soft Tissue Modifications By Postmortem Scavengers, Jennifer Ann Synstelien

Doctoral Dissertations

This study documented animal scavengers at the University of Tennessee’s Anthropology Research Facility. Remotely-captured digital video and still photography equipment was stationed at the outdoor human decomposition facility intermittently from September 2003 through October 2009. The primary scavengers of corpses were identified as the northern raccoon (Procyon lotor), Virginia opossum (Didelphis virginiana), brown rat (Rattus norvegicus), and white-footed mouse (Peromyscus leucopus); and the primary scavenger of skeletal remains was the eastern gray squirrel (Sciurus carolinensis). Among these species, the raccoon was the dominant scavenger and is the focus of this report.

The captured imagery of …

The Political Ecology Of Early Childhood Lead Exposure At The New York African Burial Ground, Joseph Jones

Doctoral Dissertations

Nearly 25 years ago federal officials unearthed over 400 skeletal remains in Lower Manhattan. The site of the excavation was the New York African Burial Ground (NYABG), a 17th- and 18th-century cemetery for the city’s mostly enslaved African population. Today, the burial ground serves as a reminder of New York’s 200-year experiment with slavery. It is the first National Monument to honor enslaved African New Yorkers. This recognition is a testament to the resolve of African American descendants and their allies who, through political activism, would see these ancestors afforded in death some of the respect denied them in life. …
