A Sediment-Based Reconstruction Of Caribbean Effective Precipitation During The ‘Little Ice Age’ From Freshwater Pond, Barbuda, Michael J. Burn, Jonathan Holmes, Lisa M. Kennedy, Allison Bain, Jim D. Marshall, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

Contemporary climate dynamics of the circum-Caribbean Region are characterized by significant precipitation variability on interannual and interdecadal timescales controlled primarily by El Niño Southern Oscillation (ENSO) and the Atlantic Multidecadal Oscillation (AMO). However, our understanding of pre-industrial climate variability in the region is hampered by the sparse geographic distribution of paleoclimate archives. Here, we present a high-resolution reconstruction of effective precipitation for Barbuda since the mid-16th Century, based on biostratigraphic and stable isotope analyses of fossil ostracods and gastropods recovered from lake sediment cores from Freshwater Pond, the only freshwater lake on the island. We interpret episodic fluctuations in shell …

Homo Heidelbergensis: The Tool To Our Success, Alexander Burkard

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Homo heidelbergensis, a physiological variant of the species Homo sapien, is an extinct species that existed in both Europe and parts of Asia from 700,000 years ago to roughly 300,000 years ago (carbon dating). This “subspecies” of Homo sapiens, as it is formally classified, is a direct ancestor of anatomically modern humans, and is understood to have many of the same physiological characteristics as those of anatomically modern humans while still expressing many of the same physiological attributes of Homo erectus, an earlier human ancestor. Since Homo heidelbergensis represents attributes of both species, it has therefore earned the classification as …

Dama Dentition: A New Tooth Eruption And Wear Method For Assessing The Age Of Fallow Deer (Dama Dama), Frazer Bowen, Ruth F. Carden, Julie Daujat, Sandrine Grouard, Holly Miller, Sophia Perdikaris, Naomi Sykes

School of Global Integrative Studies: Faculty Publications

Reliable aging techniques for wild animals are notoriously challenging to develop because of the scarcity of sizeable collections of known-age specimens. Without such techniques it is difficult to reconstruct hunting patterns, which is a significant problem for the examination of assemblages from pre-farming cultures. This paper presents a new method, based on mandibular tooth eruption and wear, for assessing the age of fallow deer. The method was developed from a large collection (n = 156) of known-age Dama dama specimens, has been blind tested by members of the zooarchaeological community and represents a user-friendly system with the potential to …

A Comparison Of The Utility Of Craniometric And Dental Morphological Data For Assessing Biodistance And Sex-Differential Migration In The Pacific Islands, Brittney A. Eubank

Graduate Student Theses, Dissertations, & Professional Papers

Genetic analysis of maternally-inherited mitochondrial DNA and the paternally-inherited Y-chromosome yield contrasting pictures of movement of peoples into the Pacific Islands. A possible explanation for this discrepancy is a matrilocal residency pattern practiced by early Pacific settlers, in which Melanesian men were brought into settler communities to intermarry with local women, yielding a higher intrapopulation variance and lower interpopulation variance exhibited in males compared to females. This research investigates the possibility of sex-differential migration in the Oceanic populations of Easter Island, Fiji, Guam, Mokapu, and New Britain through analysis of biodistance based on dental morphological trait frequencies and craniometric measures …

Utilizing Craniometrics To Examine The Morphological Changes To Homo With The Advent Of Processing Food By Cooking, Julia Schorr

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the extent to which the development of cooking by early humans contributed to morphological changes in the human skull, hypothesizing that the cooking of food by early humans had a direct effect on human evolution, leading to smaller face shape, larger body size, and larger brain development, which can be measured in the skull using craniometrics. Beginning with Homo erectus around 1 million years ago, early humans began cooking food. By beginning the process of physical and chemical breakdown of food prior to consumption, humans were able to better access calories and nutrients already found in their …

The Bridge River Dogs: Interpreting Adna And Stable Isotope Analysis Collected From Dog Remains, Emilia Tifental

Graduate Student Theses, Dissertations, & Professional Papers

Excavations at the Bridge River site have been on-going since 2003, increasing our understanding of the communities that inhabited the Middle Fraser Canyon, British Columbia over 1,000 years ago. The most recent excavation at Housepit 54 in the summer of 2014 supplied further data regarding relationships between people and their dogs. Dogs are well documented in the Middle Fraser Canyon through both archaeological excavations and traditional knowledge. A household's possession of a dog has been linked to other prestigious materials, and therefore been interpreted as an indicator of wealth and status. The present study was aimed at further investigation of …

An Evaluation Of The Effectiveness Of Eukaryotic Dna Extraction From Burial Soil Samples, Ariane Thomas

Graduate Student Theses, Dissertations, & Professional Papers

DNA is a valuable resource as a unique identifier of physical characteristics at both the population and individual levels. Due to a variety of factors that contribute to genetic decay, forensic and bioarchaeological investigators have limited outlets in which to extract viable DNA after most of a body’s organic materials have fully decomposed. This preliminary research focused on extracting DNA from the soil surrounding buried Sus scrofa domesticus cadavers to confirm the presence of viable and analyzable DNA. After a decomposition period of five months in Montana, soils were collected at incremental distances above the remains and sequenced to identify …

Paleoparasitological Evidence Of Pinworm (Enterobius Vermicularis) Infection In A Female Adolescent Residing In Ancient Tehran (Iran) 7000 Years Ago, Niloofar Paknazhad, Gholamreza Mowlavi, Jean Dupouy Camet, Mohammad Esmaeili Jelodar, Iraj Mobedi, Mahsasadat Makki, Eshrat Beigom Kia, Mostafa Rezaeian, Mehdi Mohebali, Siamak Sarlak, Faezeh Najafi

Harold W. Manter Laboratory of Parasitology: Library Materials

Background: The Molavi street archeological site south of Tehran, Iran accidentally provided a unique opportunity for paleoparasitological studies in Iran. A female skeleton was unearthed and evaluated to be 7,000 years old. Soil samples were collected around the pelvic and sacrum bones.

Findings: Careful microscopic investigation of rehydrated soil samples revealed the presence of one Enterobius vermicularis egg attached to the skeleton sacral region.

Conclusion: The present finding likely represents the oldest evidence of a human pinworm infection in Asia.

Species Identification Of The Stylohyoid Bone For North American Artiodactyls, Thomas A. Hale

All Master's Theses

Zooarchaeologists cannot identify mammal species by their stylohyoid bones. Current trends in zooarchaeological research stress the need for rigorous and accessible identification methodology. I examined the stylohyoids of 15 hooved mammals: cattle, bison, domestic sheep, bighorn sheep, Dall sheep, mountain goat, domestic goat, elk, caribou, white-tailed deer, mule deer, moose, pronghorn antelope, domestic pig, and horse. Objectives included documenting how to side the stylohyoid (left or right), and producing species identification criteria based on large samples. A total of 325 samples were measured from eight repositories. Written descriptions, photographs, and success ratios for metrics and distinct traits are included for …

Adaptability In A Bhutanese Refugee Community: Navigating Integration And The Impacts On Nutritional Health After U.S. Resettlement, Chris Grosh

Theses and Dissertations--Anthropology

Increasing rates of overweight, obesity, and related metabolic diseases documented among refugee communities across the United States necessitate greater attention to how processes of integration impact refugee health. These nutritional health trends (e.g., increasing rates of obesity) suggest potential disconnects between refugees' past environments and their conditions after re-settlement, which may contribute to adverse changes in energy balance (diet and exercise). While Bhutanese refugees were among the largest refugee groups entering the US during the five years leading up to this research, very few studies have examined how they have responded to integration and the impact of this transition on …

Dietary Adaptations And Intra- And Interspecific Variation In Dental Occlusal Shape In Hominin And Non-Hominin Primates, Kelsey O'Neill

Theses and Dissertations

Dental morphology and tooth shape have been used to recreate the

dietary adaptations for extinct species, and thus dental variation can provide

information on the relationship between fossil species and their

paleoenvironments. Variation in living species with known behaviors can provide

a baseline for interpreting morphology, and behavior, in the fossil record.

Tooth occlusal surface outlines in hominins and non-hominin primates, and other

mammals, have been used for assessments of taxonomic significance, with

variability often considered as being primarily phylogenetic. Few studies have

attempted to assess how diet might influence the pattern of variability in closely

related species. Here the …

Play In Immature Tibetan Macaques (Macaca Thibetana): Location, Use Of Play Signals, And Play Bout Termination At Mt. Huangshan, China, Kaitlin R. Wright

All Master's Theses

In this study, I examined the relationship between play behaviors, play location, the frequency of selected play signals, and play bout termination in Tibetan macaques (Macaca thibetana) during immature social play. I gathered video data at the Valley of the Wild Monkeys, Mt. Huangshan, China, and focused on 21 juvenile and infant macaques (zero to five years of age). I used an all occurrence sampling method to score play behaviors and play signals with an ethogram. I hypothesized that play groups would use play signals in functionally appropriate ways based on the location of the play bout, the …

Reaction To Stimulus Figures In Chimpanzee Drawings, Alexandra Bobrinskoy Casti

All Master's Theses

Seven captive chimpanzees (Pan troglodytes) produced drawings at the University of Oklahoma between November 1971 and November 1972. Chimpanzees drew on sheets of paper that were either blank or had a stimulus. The stimulus was located in the center or offset from the center. These drawings were scanned and digitized. Analysis tested whether chimpanzee mark placement was contingent on the location of stimulus figures. Centroid locations significantly changed between stimulus type for all drawing categories and among participants for free choice and central figure drawings. Participants drew in the empty space opposite offset figure drawings. Findings support previous …

Bioarchaeological Analysis Of Oak View Landing (40dr1): An Archaic Population In The Kentucky Lake Reservior, Katy D. Grant-Mclemore

Master's Theses

The biocultural examination of the Archaic population recovered at Oak View Landing (40DR1) investigates the lifeways and adaptations of prehistoric people as they reflect sociopolitical and subsistence strategies.

A comprehensive bioarchaeological analysis was conducted on the adult individuals (18 males, 16 females, 16 of indeterminate sex) excavated from a multiple occupation site located along the Tennessee River in Decatur County, Tennessee. Skeletal indicators used to understand biocultural phenomena were assessed macroscopically on cranial and postcranial elements. Furthermore, mortuary data, for adults and subadults, were used to determine any patterns of preferential treatment at death.

Results from this study indicate that …

Burial Chronological Sequencing Of The Colonial Maya Cemetery At Tipu, Belize Using Fluoride Ion Analysis, Nicole Musselwhite

Master's Theses

This thesis ascertains the sequence of burials using fluoride ion electrode analysis at the colonial cemetery at Tipu, Belize in order to explore demographic and other cultural effects associated with European contact. The cemetery at Tipu in west central Belize, dating from within the first century of Spanish contact, has provided one of the largest and best preserved Maya skeletal series, with over 500 burials recovered. While this series has undergone vast amounts of analysis, there has yet been an analysis conducted to view how patterns changed over time. This is of interest given the rapid culture change associated with …

Paleopathology At The Shady Grove Site (22qu525): A Study Of Health In The Upper Yazoo Basin During The Middle Mississippian Period, Christopher Brady Davis

Master's Theses

The Mississippian Period (AD 1000-1539) is characterized by increasingly sedentary populations, mound building, ranked societies, and intensified agriculture. As agriculture spread throughout the Eastern Woodlands, it led to widespread health consequences, including poor nutrition and increased levels of infection. Also, environmental shifts during the Mississippian Period (AD 1000-1539) caused drier conditions, potentially leading to crop failures further exacerbating nutritional problems.

This thesis focuses on the health of the Shady Grove site in the Upper Yazoo Basin, a Middle to Late Mississippian medium sized mound center where an ossuary containing up to 100 individuals was excavated in 2010. Focusing only on …

Patterns In Faunal Remains At Fort St. Joseph, A French Fur Trade Post In The Western Great Lakes, Joseph Hearns

Masters Theses

Faunal studies have the potential to detect a variety of patterns in animal processing activities at an archaeological site. The spatial relationships of taphonomic mechanisms observed within the animal bone assemblage illuminate the use of space on a site as well as the patterns of waste discard. Patterns within the formation processes influencing the distribution of faunal remains serve as the basis for interpretation of animal processing behaviors. This study analyzes a sample of animal bones from Fort St. Joseph (20BE23), an eighteenth-century French fur trade post in the western Great Lakes region. This post was a hub of exchange …

Helminth Infection, Fecundity, And Age Of First Pregnancy In Women, Aaron D. Blackwell, Marilyne D. Tamayo, Bret Beheim, Benjamin C. Trumble, Jonathan Stieglitz, Paul L. Hooper, Melanie Martin, Hillard Kaplan, Michael Gurven

ESI Publications

Infection with intestinal helminths results in immunological changes that influence the odds of comorbid infections, and might also affect fecundity by inducing immunological states supportive of conception and pregnancy. Here we investigate associations between intestinal helminths and fertility in human females, utilizing nine years of longitudinal data from 986 Bolivian forger-horticulturalists, experiencing natural fertility and a 70% helminth prevalence. We find that different species of helminth are associated with opposing effects on fecundity. Infection with roundworm (Ascaris lumbricoides) is associated with earlier first births and shortened interbirth intervals, while infection with hookworm is associated with delayed first pregnancy and extended …

Natural Sleep And Its Seasonal Variations In Three Pre-Industrial Societies, Gandhi Yetish, Hillard Kaplan, Michael Gurven, Brian Wood, Herman Pontzer, Paul R. Manger, Charles Wilson, Ronald Mcgregor, Jerome M. Siegel

ESI Publications

How did humans sleep before the modern era? Because the tools to measure sleep under natural conditions were developed long after the invention of the electric devices suspected of delaying and reducing sleep, we investigated sleep in three preindustrial societies[1–3]. We find that all three show similar sleep organization, suggesting that they express core human sleep patterns, likely characteristic of pre-modern era Homo sapiens. Sleep periods, the times from onset to offset, averaged 6.9–8.5-h, with sleep durations of 5.7–7.1-h, amounts near the low end of those industrial societies[4–7]. There was a difference of nearly 1-h between summer and winter sleep. …

Calcaneal Quantitative Ultrasound Indicates Reduced Bone Status Among Physically Active Adult Forager-Horticulturalists, Jonathan Stieglitz, Felicia C. Madimenos, Hillard Kaplan, Michael Gurven

ESI Publications

Six months of exclusive breastfeeding (EBF) is considered optimal for infant health, though globally most infants begin complementary feeding (CF) earlier—including among populations that practice prolonged breastfeeding. Two frameworks for understanding patterns of early CF emerge in the literature. In the first, maternal and infant needs trade-off, as “maternal-centric” factors—related to time and energy demands, reproductive investment, cultural influences, and structural barriers— favor supplanting breastfeeding with earlier and increased CF. A second framework considers that “infant-centric” factors—related to infant energetic needs—favor CF before six months to supplement breastfeeding.

We apply these two frameworks in examining early CF among the Tsimane—a …

An Investigation Into Human To Dog Attachment Systems And Their Influence On The Degree Of Aversion Used In Training, Shelly Volsche

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of my Master’s Thesis research is to determine if and what type of relationship exists between owner-to-dog attachment levels and the degree of aversion used in dog training. I also sought to determine if owner characteristics such as parental status, income, gender, and the like influenced the degree of aversion used. My primary hypothesis is that a negative correlation exists between attachment to one’s dog and aversion used in training. That is, as attachment scores increase, aversion scores decrease. In addition to testing this hypothesis, I collected data to determine if there are correlations between the following: gender …

Effects Of Human Maternal Placentophagy On Maternal Postpartum Iron-Status, Laura Kathleen Gryder

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recently, human maternal placenta ingestion, known as placentophagy, has emerged as a rare but growing practice among postpartum mothers in industrialized societies, and is currently found in both home birth and hospital birth settings. The practice is purported to result in certain health benefits for postpartum mothers, some of which could be related to the iron content in full-term placenta (e.g., increased energy and an improved and more rapid postpartum recovery, among others). The aim of this research project was to investigate the effect of encapsulated placentophagy on maternal postpartum iron status via a randomized, double-blind, placebo-controlled pilot study (n=28). …

Does Market Integration Buffer Risk, Erode Traditional Sharing Practices And Increase Inequality? A Test Among Bolivian Forager-Farmers, Michael Gurven, Adrian V. Jaeggi, Christopher Von Rueden, Paul L. Hooper, Hillard Kaplan

ESI Publications

Sharing and exchange are common practices for minimizing food insecurity in rural populations. The advent of markets and monetization in egalitarian indigenous populations presents an alternative means of managing risk, with the potential impact of eroding traditional networks. We test whether market involvement buffers several types of risk and reduces traditional sharing behavior among Tsimane Amerindians of the Bolivian Amazon. Results vary based on type of market integration and scale of analysis (household vs. village), consistent with the notion that local culture and ecology shape risk management strategies. Greater wealth and income were unassociated with the reliance on others for …

Mongolians In The Genetic Landscape Of Central Asia: Exploring The Genetic Relations Among Mongolians And Other World Populations, Jane E. Brissenden, Judith R. Kidd, Baigalmaa Evsanaa, Ariunaa Togtokh, Andrew J. Pakstis, Françoise Friedlaender, Kenneth K. Kidd, Janet M. Roscoe

Human Biology Open Access Pre-Prints

Genetic data on North Central Asian populations are underrepresented in the literature, especially autosomal markers. In the present study we use 812 single nucleotide polymorphisms that are distributed across all the human autosomes and that have been extensively studied at Yale to examine the affinities of two recently collected, samples of populations: rural and cosmopolitan Mongolians from Ulaanbaatar and nomadic, Turkic-speaking Tsaatan from Mongolia near the Siberian border. We compare these two populations to one another and to a global set of populations and discuss their relationships to New World populations. Specifically, we analyze data on 521 autosomal loci (single …

Depression As Sickness Behavior? A Test Of The Host Defense Hypothesis In A High Pathogen Population, Jonathan Stieglitz, Benjamin C. Trumble, Melissa Emery Thompson, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven

ESI Publications

Sadness is an emotion universally recognized across cultures, suggesting it plays an important functional role in regulating human behavior. Numerous adaptive explanations of persistent sadness interfering with daily functioning (hereafter “depression”) have been proposed, but most do not explain frequent bidirectional associations between depression and greater immune activation. Here we test several predictions of the host defense hypothesis, which posits that depression is part of a broader coordinated evolved response to infection or tissue injury (i.e. “sickness behavior”) that promotes energy conservation and reallocation to facilitate immune activation. In a high pathogen population of lean and relatively egalitarian Bolivian foragerhorticulturalists, …

Origins Of An Unmarked Georgia Cemetery Using Ancient Dna Analysis, Andrew T. Ozga, Raúl Y. Tito, Brian M. Kemp, Hugh Matternes, Alexandra Obregon-Tito, Leslie Neal, Cecil M. Lewis, Jr.

Human Biology Open Access Pre-Prints

Determining the origins of those buried within undocumented cemeteries is of incredible importance to historical archaeologists and in many cases, the nearby communities. In the case of Avondale Burial Place, a cemetery in Bibb County, Georgia, in use from 1820 to 1950, all written documentation of those interred within it has been lost. Osteological and archaeological evidence alone could not describe, with confidence, the ancestral origins of the 101 individuals buried there. In the present study, we utilize ancient DNA extraction methods to investigate the origins of Avondale Burial Place through the use of well-preserved skeletal fragments from 20 individuals …

Reproductive Genetics: Desired Genes, Gendered Ethics, And Eugenic Echoes, Marykate K. Bodnar

The Hilltop Review

Present knowledge of genetics and assisted reproduction make fertile ground for a new type of eugenics: reproductive genetics. Proponents of reproductive genetics aim to separate these techniques from the problematic and negative connotations associated with historical eugenic policies by claiming them as part of the liberal eugenic movement. In-vitro fertilization (IVF), the market for sperm and eggs, and prenatal genetic testing allow conscious decision-making regarding the potential genetic make-up of children. Decisions are made in a gendered and politicized environment, shaping understandings of genes, eggs, and sperm around stereotypes and ideal social norms. In choosing “desirable” characteristics, whatever they may …

La Souffrance Animale À Distance: Des Vétérinaires Dans L’Action Humanitaire, Frédéric Keck, Miriam Ticktin

Publications and Research

Résumé

Cet article étudie le rôle des vétérinaires dans l’humanitaire à partir de deux types de pratique : la défense des animaux contre la cruauté et la surveillance des animaux touchés par les épidémies. En suivant l’extension de l’action humanitaire aux animaux comme nouvelles figures de victimes innocentes, nous cherchons à dépasser l’approche compassionnelle de l’humanitaire pour étudier les nouvelles formes scientifiques impliquant des non-humains, comme la médecine vétérinaire légale, les neurosciences et l’immunologie. Nous soutenons finalement que ces sciences produisent de nouveaux collectifs d’humains et de non-humains.

Abstract

This article traces the role of veterinarians in humanitarian action, focusing …

Lambda Alpha Anthropology Honors Society (Lab): Bridging The Gap Between Coursework And Career, Adriana Stein, Stefanie Berganini

Student Research Symposium

Many anthropology majors gain an academic familiarity with the subject through coursework, but lack an understanding of how to utilize their anthropological skills outside of academia in future careers. To remedy this issue, the Lambda Alpha Beta Honor Society (LAB), a student-led anthropology organization at Portland State University, provides opportunities for participation in events that get students involved with our local community, such as non-profit organizations and local cultural institutions. Some of these organizations include the Oregon Museum of Science and Industry (OMSI), Clark Public Utilities, The Ridgefield Wildlife Refuge, Potluck in the Park, and Habitat for Humanity. As an …
