A Comparison Of Craniofacial Asymmetry In Gorilla Gorilla Gorilla And Pan Troglodytes Troglodytes, Ashly Noel Romero

Graduate Theses and Dissertations

Fluctuating asymmetry (FA) – random deviations from bilateral symmetry in an organism’s paired features – is a good candidate for investigating developmental stability. This easily accessible measurement can be used to understand the relationship between stress and development across organisms, and growth rate plays a vital role in developmental processes. Few studies have investigated craniofacial FA in non-human primates, and those that have suggest that levels of FA are higher in slower growing species. This study examines craniofacial FA in two primate species (Pan troglodytes troglodytes and Gorilla gorilla gorilla; n=81) to elucidate the effect of growth rate on FA …

Sociality And Stress In Female Chacma Baboons (Papio Ursinus) In The Cape Peninsula Of South Africa: Behavioral Flexibility And Coping Mechanisms, Shahrina Chowdhury

Dissertations, Theses, and Capstone Projects

The physiological stress responses that animals exhibit to the myriad stressors in their environment can be used to assess the state of their health and well-being, and even survival capability. Although the stress response is adaptive in many cases, chronic stress responses may be maladaptive in some situations when it leads to dysfunction of the physiological system involved in the stress response itself, and can also cause deleterious effects on health, reproduction and survival. The stress response includes physiological responses to both environmental perturbations and psychosocial stress and anxiety associated with social perturbations. The latter factor is particularly important for …

Gender And Religion In A Shifting Social Landscape: Anglo-Saxon Mortuary Practices, Ad 600-700, Caroline Palmer

Undergraduate Honors Theses

My thesis examines seventh-century East Anglian mortuary practices and cross-correlates grave goods and human remains to determine whether there was an expression of the sexual division of labor during this period of social and religious change. I argue that gender roles changed as a result of adopting kingdoms and Christianity. Prior to this time period, Anglo-Saxons were primarily pagan and were buried with extensive burial goods. In addition to changes in religious and burial practices, during the Final Phase (600-700 AD) there appears to have been a division of labor that was not as dichotomous in the Migration Phase (450-600 …

Metacarpal Ratio And Its Relation To Sexual Dimorphism In Primates With Different Mating Strategies, Emilee Hart

LSU Master's Theses

The digit ratio (2D:4D) is a sexually dimorphic trait in mammalian hands that is a result of levels of prenatal androgen exposure (PNAE) during limb development. Previous studies have shown that females have a higher ratio than males and that sexual dimorphism in the ratio is greater in species with polygynous mating strategies and high levels of intermale aggression compared to monogamous species with low intermale aggression. This study used metacarpals instead of phalanges to test the hypotheses that the metacarpal ratio (2Mc:4Mc) will be higher in females than males within a species and that the ratio would be more …

Mortuary Patterns In West-Central Tennessee: Contextualizing Historic Field Data From Nine Mississippian Period Sites, Brooke Adele Wamsley

Theses and Dissertations

Middle Mississippian is a both a cultural and temporal (1200 CE – 1400 CE) archaeological context of Midwestern North America. This cultural tradition is associated with mound building, specific art motifs, arguably stratified societies, intensive agriculture, and specific ritual/mortuary practices. Burial sites can be very valuable to archaeologists because of the purposeful interaction between the living and the deceased and reconstruct cultural elements such as social identity and group membership. While American archaeology continues to be fieldwork-focused, there are a considerable amount of cultural resources housed in museum collections that could provide data for research into pre-Columbian lifeways in North …

Sex Differences In Political Leadership In An Egalitarian Society, Christopher Von Rueden, Sarah Alami, Hillard Kaplan, Michael Gurven

ESI Publications

We test the contribution of sex differences in physical formidability, education, and cooperation to the acquisition of political leadership in a small-scale society. Among forager-farmers from the Bolivian Amazon, we find that men are more likely to exercise different forms of political leadership, including verbal influence during community meetings, coordination of community projects, and dispute resolution. We show that these differences in leadership are not due to gender per se but are associated with men’s greater number of cooperation partners, greater access to schooling, and greater body size and physical strength. Men’s advantage in cooperation partner number is tied to …

The Structural Violence Of Maya Sacrifice: A Case Study Of Ritualized Human Sacrifice At Midnight Terror Cave, Belize, C. L. Kieffer Nail

Anthropology ETDs

The site of Midnight Terror Cave is located in the karstic Roaring Creek Valley near the village of Springfield in the Cayo District of Belize. The site was discovered in 2006 and fieldwork was conducted by the Western Belize Regional Cave Survey Project and California State University, Los Angeles, between 2008 and 2010. This dissertation focuses on the osteological analysis of the bones of 118 individuals recovered and recorded at the site. The osteological, contextual, and demographic evidence is framed within ritual and costly signaling theory of structural violence and viewed with the ethnohistoric and ethnographic literature of the ancient …

Low Perceived Control Over Health Is Associated With Lower Treatment Uptake In A High Mortality Population Of Bolivian Forager-Farmers, Sarah Alami, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven

ESI Publications

Indigenous people worldwide suffer from higher rates of morbidity and mortality than neighboring populations. In addition to having limited access to public health infrastructure, indigenous people may also have priorities and health perceptions that deter them from seeking adequate modern healthcare. Here we propose that living in a harsh and unpredictable environment reduces motivation to pursue deliberate, costly action to improve health outcomes. We assess whether variation in Health Locus of Control (HLC), a psychological construct designed to capture self-efficacy with respect to health, explains variation in treatment uptake behavior among Tsimane Amerindians (N=690; age range: 40–89 years; 55.8% female; …

Worldwide Distribution Of The Human Apolipoprotein E Gene - The Association Between Apoe, Subsistence, And Latitude, Tiffany S. Ho

Theses and Dissertations

The human apolipoprotein E gene (APOE) plays an important role in metabolizing lipids, regulating plasma cholesterol, and maintaining biological function. Structural differences in APOE variants impact cholesterol absorption and health risk, so that alleles serve as biomarkers for numerous cardiovascular and neurological diseases (Lai 2015). Variant differences are determined by changes in two single nucleotide polymorphisms (SNPs), rs429358 and rs7412. Distribution of alleles varies across populations. Allele frequencies in populations have been shown to be associated with cultural and environmental factors, including subsistence strategy and latitude (Eisenberg 2010).

This study aims to provide a cross-population, genetic association study …

A Bioarchaeological Study Of Osteoarthritis Of Agro-Pastoralists From Mistihalj, Bosnia And Herzegovina: A Lifestyle Set In Time, Zorina Manoni

Electronic Theses and Dissertations

Activity stresses are an important factor in the development, patterning, and severity of osteoarthritis. This bioarchaeological thesis explores the prevalence and patterning of osteoarthritis between individuals buried at a Late Medieval Necropolis and a church Crypt built in the 19th century at the Mistihalj site in Bosnia and Herzegovina to understand the physiological effects of their peasant agro-pastoralist lifestyle. Composite scores of osteoarthritis were generated for visual observations of upper limb joints (shoulder, elbow, and wrist) and lower limb joints (hip, knee, and ankle) of 37 female and 39 male adult (between 20 and 50 or more years of age) …

Evolution Of The Modern Baboon (Papio Hamadryas): A Reassessment Of The African Plio-Pleistocene Record, Christopher C. Gilbert, Stephen R. Frost, Kelsey D. Pugh, Monya Anderson, Eric Delson

Publications and Research

Baboons ( Papio hamadryas) are among the most successful extant primates, with a minimum of six distinctive forms throughout Sub-Saharan Africa. However, their presence in the fossil record is unclear. Three early fossil taxa are generally recognized, all from South Africa: Papio izodi , Papio robinsoni and Papio angusticeps. Because of their derived appearance, P. angusticeps and P. robinsoni have sometimes been considered subspecies of P. hamadryas and have been used as biochronological markers for the Plio- Pleistocene hominin sites where they are found.

We reexamined fossil Papio forms from across Africa with an emphasis on their distinguishing features and …

Allometric Variation In Modern Humans And The Relationship Between Body Proportions And Elite Athletic Success, Tesla A. Monson, Marianne F. Brasil, Leslea J. Hlusko

Anthropology Faculty and Staff Publications

In many sports, greater height and arm span are purportedly linked to athletic success. While variation in body proportions has been explored across an array of scientific disciplines, studies focusing on humans of tall stature outside of clinical cases are limited. We investigated body size proportions in a sample of elite athletes, employing data on recruits for the National Basketball Association (NBA, n=2,990), mixed martial arts (MMA) fighters (mixed-sex, n=1,284), as well as a control sample of healthy young adults who are not professional athletes, represented here by male (n=4,082) and female (n=1,986) recruits for the United States Army, to …

Science At Engineer Cantonment, Hugh H. Genoways, Brett C. Ratcliffe, Carl R. Falk, Thomas E. Labedz, Paul R. Picha, John R. Bozell

University of Nebraska State Museum: Mammalogy Papers

Conclusions

It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

Mitochondrial Dna Analysis Of Mazahua And Otomi Indigenous Populations From Estado De Mexico Suggests A Distant Common Ancestry, Angelica GonzáLez-Oliver, Ernesto Garfias-Morales, D G. Smith, Mirsha Quinto-Sánchez

Human Biology Open Access Pre-Prints

The indigenous Mazahua and Otomi have inhabited the same localities in Estado de Mexico since pre-Columbian times. Their languages, Mazahua and Otomi, belong to the Otomanguean linguistic family, and, while they share cultural traditions and a regional history that suggest close genetic relationships and common ancestry, the historical records concerning their origin are confusing. To understand the biological relationships between Mazahua and Otomi we analyzed the mitochondrial DNA (mtDNA) genetic variation. We identified the mtDNA haplogroups by restriction fragment length polymorphism typing and sequenced the hypervariable region I of the mtDNA control region in 141 Mazahua and 100 Otomi. These …

Testosterone And The Adult Male, Alex Straftis

Calvert Undergraduate Research Awards

Abstract

In the last 15 years, prescription testosterone sales have increased almost threefold. Testosterone is a powerful hormone, which has both physiological and behavioral effects on the adult male. These effects vary over a man’s life course and social ecology. In a natural setting, testosterone reaches a peak during early adulthood, declines gradually over midlife, and has exponential drops after the age of 70. Increasing testosterone, through testosterone replacement therapy (TRT), past early adulthood, is an evolutionary novel circumstance for an adult male. To gauge these effects, and the motivations that initiated them, this study conducted a preliminary text analysis …

Stress And Frailty In Medieval Prussia: Interpretations From Skeletal Remains At Bezławki, Katherine E. Gaddis

Cal Poly Humboldt theses and projects

Health is routinely studied in living populations using quantifiable measurements such as allostatic load and frailty. In recent years, particularly since the introduction of the osteological paradox, there has been increased interest among bioarchaeologists in how these concepts can be applied to the study of health in past populations. Although health is not directly observable in skeletal remains, assessment of frailty can be useful for understanding the implications of long-term exposures to stress on well-being and mortality. This study builds upon past research in this area by incorporating commonly observed indicators of physiological stress, such as dental disease and osteoarthritis, …

Psychotropic Medications And Children: Perceptions Of Mental Health Professionals, Elinor Jane Brereton

Electronic Theses and Dissertations

This project explores mental health professionals' perspectives on the prescription of psychotropic medications to children. It emphasizes the placement of biomedicine within its larger social, economic, and political context, and the influence these structures have on the way mental illness is conceptualized and treated in children. Eight semi-structured interviews were conducted in Denver, Colorado with psychiatrists, psychologists, social workers, and a pharmaceutical board member to capture multiple perspectives from different positionalities within the field. Participants discussed factors that they believe influence prescribing practices including: professional role changes, issues of access, limited evidence, cost, and institutional pressures to practice within a …
