The Impacts Of Environment And Host Evolutionary Relationships On Lemur Microbiota, Rachel B. Burten Mar 2024

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 Nov 2023

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 …


Diversity And Evolution Of Human Eccrine Sweat Gland Density, Andrew W. Best Oct 2021

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. …


Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos Sep 2021

Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos

Masters Theses

Primate hair is both a substrate upon which essential social interactions occur and an important host-pathogen interface. As commensal microbes provide important immune functions for their hosts, understanding the microbial diversity in primate hair could provide insight into primate immunity and disease transmission. While studies of human hair and skin microbiomes show differences in microbial communities across body regions, little is known about the nonhuman primate hair microbiome. In this study, we collected hair samples (n=159) from 8 body regions across 12 nonhuman primate species housed at 3 US institutions to examine 1) the diversity and composition of the primate …


Grandmotherhood In Ukraine: Behavioral Variation And Evolutionary Implications, Sofiya Shreyer Dec 2020

Grandmotherhood In Ukraine: Behavioral Variation And Evolutionary Implications, Sofiya Shreyer

Masters Theses

Grandmothers are known to increase the health and well-being of their grandchildren in many different populations. However, grandmothers may vary in their contributions based on their relatedness to their grandchildren. In some populations, maternal grandmothers decrease the risk of mortality and increase the health of their grandchildren more than paternal grandmothers. Grandmaternal influence also sometimes varies based on the gender of the grandchild. The behavioral mechanisms of grandmaternal investment are not well understood and have not been explored in the heavily intergenerational context of Eastern Europe. This study examines the behavioral variation of sixty-two Ukrainian grandmothers through interviews and a …


De-Coding The Impact Of Evolved Changes In Gene Expression And Cellular Phenotype On Primate Evolution, Trisha Zintel Feb 2020

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 …


Archery's Lasting Mark: A Biomechanical Analysis Of Archery, Tabitha Dorshorst Oct 2019

Archery's Lasting Mark: A Biomechanical Analysis Of Archery, Tabitha Dorshorst

Masters Theses

The physical demands of archery involve strenuous movements that place repetitive mechanical loads on the upper body. Given that bone remodels in response to mechanical loading (Ruff, 2008), it is reasonable to assume that repetitive bow and arrow use impacts upper limb bone morphology in predictable ways. The introduction and increased use of archery have been suggested to impact bilateral humeral asymmetry (Rhodes and Knüsel, 2005; Thomas, 2014). However, this claim is yet to be tested in vivo. This project aims to use kinematic and electromyographic approaches to validate claims inferring that, 1. archery places mechanical loading on the non-dominant …


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 Nov 2017

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 …


The Effects Of Industrialization And Urbanization On Growth And Development: A Comparison Of Boys And Girls From Three Industrial European Skeletal Collections, Sarah Reedy Jul 2017

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 Jul 2017

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 …


Effects Of Terrain On Reconstructions Of Mobility In Past Populations, Erin M. Whittey Mar 2017

Effects Of Terrain On Reconstructions Of Mobility In Past Populations, Erin M. Whittey

Masters Theses

Femoral and tibial diaphyseal geometry has frequently been used to evaluate mobility and other patterns of physical activity in past populations. The high antero-posterior (A-P) to medio-lateral (M-L) bending rigidity ratio (IX/IY) typical of many hunter-gatherer femora, for instance, may reflect mechanical loads associated with long distance travel. The possible confounding effect of physical terrain on lower limb diaphyseal morphology is rarely evaluated. This study investigated the possible effect of terrain on lower limb shape ratios (IX/IY) and bending and torsional strength (ZP) in adult skeletons from Europe, North America, …


Illegal Hunting On The Masoala Peninsula Of Madagascar: Its Extent, Causes, And Impact On Lemurs And Humans, Cortni Borgerson Aug 2015

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 …


Food And Diet In The Andes: Changing Markets And Lives In Nuñoa, James A. Fisher Jul 2015

Food And Diet In The Andes: Changing Markets And Lives In Nuñoa, James A. Fisher

Masters Theses

The town of Nuñoa, located in the southern Peruvian Andes, has been the ongoing focus of anthropological research. Household surveys of diet and food security (n=69) administered during 2012 are analyzed here and compared to past studies from previous decades. Study results show clearly that the amount and diversity of new foods available in the area has increased dramatically, but also gives evidence for continued disparate access to certain types of food along class lines. Socioeconomic status had a significant negative correlation with food insecurity and poor households more frequently consumed both potatoes and other cheap, high carbohydrate foods such …


The Political Ecology Of Early Childhood Lead Exposure At The New York African Burial Ground, Joseph Jones Mar 2015

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. …


Were Neandertal Humeri Adapted For Spear Thrusting Or Throwing? A Finite Element Study, Michael Anthony Berthaume Nov 2014

Were Neandertal Humeri Adapted For Spear Thrusting Or Throwing? A Finite Element Study, Michael Anthony Berthaume

Masters Theses

An ongoing debate concerning Neandertal ecology is whether or not they utilized long range weaponry. The anteroposteriorly expanded cross-section of Neandertal humeri have led some to argue they thrusted their weapons, while the rounder cross-section of Late Upper Paleolithic modern human humeri suggests they threw their weapons. We test the hypothesis that Neandertal humeri were built to resist strains engendered by thrusting rather than throwing using finite element models of one Neandertal, one Early Upper Paleolithic (EUP) human and three recent human humeri, representing a range of cross-sectional shapes and sizes. Electromyography and kinematic data and articulated skeletons were used …
