From Icon Of Empire To National Emblem: New Evidence For The Fallow Deer Of Barbuda, Sophia Perdikaris, Allison Bain, Sandrine Grouard, Karis Baker, Edith Gonzalez, A. Rus Hoelzel, Holly Miller, Reaksha Persaud, Naomi Sykes

School of Global Integrative Studies: Faculty Publications

Barbuda and Antigua’s national animal is the fallow deer, Dama dama dama, a species native to the eastern Mediterranean that has been transported around the world by people during the last 8000 years. The timing and circumstances by which fallow deer came to be established on Barbuda are currently uncertain but, by examining documentary, osteological and genetic evidence, this paper will consider the validity of existing theories. It will review the dynamics of human–Dama relationships from the 1500s AD to the present day and consider how the meaning attached to this species has changed through time: from a …

Evaluating Nubian Population Structure From Cranial Nonmetric Traits: Gene Flow, Genetic Drift, And Population History Of The Nubian Nile Valle, Kanya Godde, Richard L. Jantz Jan 2018

Evaluating Nubian Population Structure From Cranial Nonmetric Traits: Gene Flow, Genetic Drift, And Population History Of The Nubian Nile Valle, Kanya Godde, Richard L. Jantz

Human Biology Open Access Pre-Prints

Paleolithic archaeological and skeletal remains from the Nile Valley have yielded a complex picture of life along the river. Sociocultural and sociopolitical events during this timeframe shaped population structure, while gene flow and genetic drift further developed it. In this paper, we take a population genetics approach to modeling Nubian biological relationships in an effort to describe how an accumulation of events formed Nubian population structure. A variety of Nubian samples were utilized, spanning the Mesolithic-Christian time periods, and geographically, from just above the first through the third cataracts. Population genetics statistics were employed to estimate and depict biological affinities …

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 …


Re-Evaluating Captive Chimpanzee “Dominance”: Dominance Hierarchy And Chimpanzee-Caregiver Relationships At Chimpanzee Sanctuary Northwest, Jake Funkhouser Jan 2018

Re-Evaluating Captive Chimpanzee “Dominance”: Dominance Hierarchy And Chimpanzee-Caregiver Relationships At Chimpanzee Sanctuary Northwest, Jake Funkhouser

All Master's Theses

This thesis is composed of two journal-ready articles and an accompanying appendix with additional data and interpretation. Overall, this thesis describes and statistically analyzes dominance relationships in two nonhuman primate groups with novel methods, possible correlations between dominance and testosterone, and uncovers the prominent connection of caregivers to captive chimpanzee social networks. Chapter I addresses current and past variability in behavioral measures and statistical methods to derive dominance rankings. I propose a novel approach to using existing statistical techniques to analyze dominance ranks, context-dependent dominant structures (agonistic competitions, lack of agonism, privileged role, priority access to resources), the reliability of …


Response Of Three Species Of Monkeys To Caregiver Use Of Species-Typical Behavior, Lillian Anna Stolar Jan 2018

Response Of Three Species Of Monkeys To Caregiver Use Of Species-Typical Behavior, Lillian Anna Stolar

All Master's Theses

Caregivers are a primary part of captive monkey environments. When addressing psychological well-being of captive nonhuman primates, social environment should be considered. Chimpanzees, gorillas, New World monkeys, and Old World monkeys responded positively to interactions with caregivers. Some species showed increased affiliative behaviors and decreased abnormal or self-directed behaviors after interactions. These studies showed that caregivers can affect the behavior of nonhuman primates. Caregivers are underutilized as a source of social interaction for captive nonhuman primates. Utilizing species-typical behaviors during interactions, caregivers and nonhuman primates can communicate and interact in different ways that may be beneficial to both caregiver and …

This Is Just A Phase : The Impact Of Population Structure On Haplotype Phasing And Linkage Disequilibrium Measures At Functional Genetic Sites., Roxanne Kaaren Leiter

Electronic Theses and Dissertations

The block-like structure of the human genome has been the subject of many scientific papers and is of practical significance in large-scale genome-wide association studies. How stringent haplotype block boundaries are within and between populations has been the subject of ongoing debate within human population genetics. This thesis will contribute to the description of universal and population-specific haplotype blocks at functional sites, namely across the IL-10 gene family (including IL-10, IL-19, IL-20 and IL-24), which is involved in a number of immune system processes, and MAPKAP-K2, an adjacent and functionally significant kinase gene. Beyond the description of blocks across these …


Leveraging Multiple Populations Across Time Helps Define Accurate Models Of Human Evolution: A Reanalysis Of The Lactase Persistence Adaptation, Chenling Xu Antelope, Davide Marnetto, Fergal Casey, Emilia Huerta-Sanchez Nov 2017

Leveraging Multiple Populations Across Time Helps Define Accurate Models Of Human Evolution: A Reanalysis Of The Lactase Persistence Adaptation, Chenling Xu Antelope, Davide Marnetto, Fergal Casey, Emilia Huerta-Sanchez

Human Biology Open Access Pre-Prints

Access to a geographically diverse set of modern human samples from the present time and from ancient remains, combined with archaic hominin samples, provides an unprecedented level of resolution to study both human history and adaptation. The amount and quality of ancient human data continues to improve, and enables tracking the trajectory of genetic variation over time. These data have the potential to help us redefine or generate new hypotheses of how human evolution occurred, and revise previous conjectures. In this review, we argue that leveraging all these data will help us better detail adaptive histories in humans. As a …

Human Biology Open Access Pre-Prints

The field of paleogenomics (the study of ancient genomes) is rapidly advancing with more robust methods of isolating ancient DNA and increasing access to next-generation DNA sequencing technology. As these studies progress, many important ethical issues have emerged that should be considered when ancient Native American remains, whom we refer to as ancestors, are used in research. We highlight a recent article by Kennett et al. (2017), “Archaeogenomic evidence reveals prehistoric matrilineal dynasty,” that brings several ethical issues to light that should be addressed in paleogenomics research (Kennett et al. 2017). The study helps elucidate the matrilineal relationships in ancient …

Human Biology Open Access Pre-Prints

The major histocompatibility complex is directly involved in the immune response and thus the genes coding for its proteins are useful markers for the study of genetic diversity, susceptibility to disease (autoimmunity and infections), transplant medicine, and pharmacogenetics, among others. The polymorphism of the system also allows researchers to use it as a proxy for population genetics analysis, such as genetic admixture and genetic structure. In order to determine the immunogenetic characteristics of a sample from the northern part of Mexico City and to use them to analyze the genetic differentiation from other admixed populations, including those from previous studies …


Ecological Niche Modeling Of The Genus Papio, Amanda J. Fuchs Aug 2017

Ecological Niche Modeling Of The Genus Papio, Amanda J. Fuchs

Theses and Dissertations

Ecological niche modeling investigates how climatic variables have influenced taxonomic diversity in Papio. Models performed well suggesting climatic variables influence the distribution of baboon species. Niche overlap among all possible pairs of taxa determined that species exhibited significantly different niches. The results of these models support a parapatric speciation scenario.


Costs Of Group Locomotion: How Infant-Carrying And Group Members Mediate Walking Speed Decisions In North American And East African Populations, Leah M. Bouterse Jun 2017

Costs Of Group Locomotion: How Infant-Carrying And Group Members Mediate Walking Speed Decisions In North American And East African Populations, Leah M. Bouterse

Honors Projects

A major portion of humans’ activity-based energy expenditure is taken up by locomotion, particularly walking. Humans can offset the energetic expenditure of walking in numerous ways, both evolutionary (such as changes in body shape) and culturally. Behaviorally, people can choose to walk in a variety of ways, including alone or with a group, carrying loads, and walking quickly or more slowly. All of these behaviors have energetic outcomes and as such can be important windows into how populations and groups adjust to different constraints. While sex differences in speed of paired walkers have been established by others, the dynamics of …

Honors Thesis Abstract Written by Samantha Tickey-McCrane, Departments of Anthropology & Biology

Advisor: Dr. Holly Dunsworth, Department of Anthropology

How did hominoid tail loss occur? My goals are to test phylogenetic and adaptive hypotheses for tail length variation among macaques, and use those insights to reconstruct the evolution of hominoid taillessness. Further, I aim to ultimately uncover which candidate genes or pathways may be responsible for catarrhine tail loss, and what other traits may be affected by …


The Diet And Subsistence Methods Of The Maya: Their Health And Cultural Consequences From The Pre-Classic Era To Today, Rachel E. Watson Apr 2017

The Diet And Subsistence Methods Of The Maya: Their Health And Cultural Consequences From The Pre-Classic Era To Today, Rachel E. Watson

Honors Undergraduate

The Maya, a once great civilization, seemingly vanished without an obvious reason, before the Spanish landed in the region. Some say that their downfall was a result of famine and inadequate nutrition. Surprisingly, most of the archaeological evidence surrounding the Classic Maya diet and subsistence methods indicates that they both adequately sustained the population to the point where there has been practically no change over hundreds of years. Change did not occur to the Maya diet or the classic subsistence methods until the late twentieth century when the tourism industry exploded in the area of the former Maya empire. The …


Mitochondrial-Dna Phylogenetic Information And The Reconstruction Of Human Population History: The South American Case, María Bárbara Postillone, S. Ivan Perez Jan 2017

Mitochondrial-Dna Phylogenetic Information And The Reconstruction Of Human Population History: The South American Case, María Bárbara Postillone, S. Ivan Perez

Objectives: Mitochondrial DNA (mtDNA) sequences are becoming increasingly important in the study of human population history. Here, we explore the differences in the amount of information of different mtDNA regions and their utility for the reconstruction of South American population history.

Material and methods: We analyzed six datasets comprising 259 mtDNA sequences from South America: Complete mtDNA, Coding, Control, hypervariable region I (HVRI), cytochrome b (cytb) plus Control, and cytb plus 12S plus 16S. The amount of information in each dataset was estimated employing several site-by-site and haplotype based statistics, distances among sequences, Neighbor-joining trees, distances among the estimated trees, …


Ancient Dna Extraction From Stone Tools, Clare Super Jan 2017

Ancient Dna Extraction From Stone Tools, Clare Super

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Proteins and DNA can be trapped in the microcracks on the surface of stone tools, which can then be extracted and analyzed to aid in inferring the use of the tool (Shanks et al. 2001; 2005). This nondestructive method involves the use of sonication to release DNA from the microcracks, then amplification of regions of mitochondrial DNA that are species specific. This technique was applied to stone tools from the Bridge River site in British Columbia by researchers at UMT’s Ancient and Modern Molecular Anthropology labs. Bridge River archaeologists have designated the tools as used in “food processing or tool …


Managing Sociality Of A Captive Female Bornean Orangutan From Breeding To Post-Partum At The Smithsonian's National Zoo, Marie Vergamini Jan 2017

Managing Sociality Of A Captive Female Bornean Orangutan From Breeding To Post-Partum At The Smithsonian's National Zoo, Marie Vergamini

Theses and Dissertations

The Association of Zoos and Aquariums’ Orangutan Species Survival Plan® aims to maintain 100 Bornean orangutans (Pongo pygmaeus) in captivity. Because investment in breeding these lineages is high, properly managing sociality of potential mothers is essential. This study assessed how behaviors of a captive breeding female at the Smithsonian’s National Zoo changed from pre-gestation through the offspring’s sixth month of age to improve breeding recommendations.

The infant Bornean orangutan was born September 2016. Results indicate that during breeding, the mother socialized most with two adult females. During pregnancy, the pregnant female socialized in less energy-consuming ways, i.e. grooming. …


Enrichment Use & Social Interactions In A Mixed-Species Enclosure Of Sumatran (Pongo Abelij) & Bornean Orangutans (P. Pygmaeus) & Northern White-Cheeked Gibbons (Nomascus Leucogenys), Emily Veitia Jan 2017

Enrichment Use & Social Interactions In A Mixed-Species Enclosure Of Sumatran (Pongo Abelij) & Bornean Orangutans (P. Pygmaeus) & Northern White-Cheeked Gibbons (Nomascus Leucogenys), Emily Veitia

All Master's Theses

Enrichment is an aspect of captive husbandry that has been shown to positively impact animals’ well-being and can be designed to encourage species-typical behaviors, such as foraging and arboreality. Enrichment can include housing together multiple compatible species. Orangutans are sympatric with siamangs and agile and Bornean gibbons, so several zoos house these four Asian ape species in the same enclosure, in part, as social enrichment. In my study, I observed enrichment use and social interactions in a mixed-species enclosure at the Oregon Zoo, which housed two Sumatran (Pongo abelii) and two Bornean (P. pygmaeus) orangutans with …


Chimpanzee (Pan Troglodytes) Space Use In A Sanctuary Setting, Holly Soubiea Jan 2017

Chimpanzee (Pan Troglodytes) Space Use In A Sanctuary Setting, Holly Soubiea

All Master's Theses

Studies of chimpanzee space use can provide information about chimpanzees’ preferences and welfare. This study examined the space use of 12 chimpanzees at Fauna Foundation, a chimpanzee sanctuary located in Carignan, Québec, Canada. Observers recorded the chimpanzees’ location, elevation, perimeter, and substrate using a scan sampling procedure. In total, there were 93 hours of data and 3,190 scans. The author used Geographical Information System (GIS) to plot the chimpanzees’ location for each scan. The chimpanzees used the largest rooms most often, were inside 61% (n = 1,942) of the time, an arm’s reach away from the perimeter 90% (n = …


The Social Behavior Of Rehabilitated Spider Monkeys (Ateles Geoffroyi), Anthony Denice Jan 2017

The Social Behavior Of Rehabilitated Spider Monkeys (Ateles Geoffroyi), Anthony Denice

All Master's Theses

The welfare of captive primates in laboratories, sanctuaries, and zoos is affected by various aspects of their environments. Although space restrictions increase aggression and stress-related behaviors in most captive animals, primates show diverse mechanisms for displacing stress and mitigating conflict. Many primates, including wild spider monkeys (genus Ateles), use these mechanisms flexibly to cope with social and environmental stressors. I investigated whether or not captive black-handed spider monkeys (Ateles geoffroyi) use behavioral strategies to cope with potential stressors in captivity. In particular, I tested whether an affiliative or avoidant strategy was used in response to changes in …


Collective Decision Making In Tibetan Macaques: How Followers Affect The Rules And Efficiency Of Group Movement, Amanda Rowe Jan 2017

Collective Decision Making In Tibetan Macaques: How Followers Affect The Rules And Efficiency Of Group Movement, Amanda Rowe

All Master's Theses

Primate societies must undergo successful collective decision making during group movement to stay cohesive and provide the ecological and evolutionary benefits of sociality. This study investigates how a fan structure facilitates successful group movement in the YA1 group of Tibetan macaques (Macaca thibetana) at Mt. Huangshan National Reserve in Anhui, China. We used structural equation modeling (SEM) to determine the relative influences of sex, age, maternal kinship, dominance, and social network centrality on the number of fans (consistent followers) an individual had, and the number of group members an individual was a fan of (fandom). SEM revealed that …


Changes In Male Hunting Returns, Raymond B. Hames Dec 2016

Changes In Male Hunting Returns, Raymond B. Hames

Department of Anthropology: Faculty Publications

Research on changes in male hunting among hunter-gatherers addresses two important issues in early human evolution: the nature of the family and trade-offs in mating and parenting effort as well as the development of embodied capital. In the hunter-gatherer literature, there is a debate about the function of male hunting that has implications for understanding the role males play in the evolution of the pair bond. The traditional model argues that male hunting and other economic activities are forms of male provisioning or parenting effort designed to enhance a man’s fitness through his wife’s reproduction and the survivorship of their …

Effect Of Migration, Carrying Capacity, And Fecundity On The Formation Of Clinal Patterns During Range Expansions., Neha J. Angal Aug 2016

Effect Of Migration, Carrying Capacity, And Fecundity On The Formation Of Clinal Patterns During Range Expansions., Neha J. Angal

Electronic Theses and Dissertations

Range expansions, empirically and in simulations, lead to clinal patterns of genetic diversity. Clines are often used as spatial markers of past migrations. This study investigated the effects of migration, growth, and carrying capacities on clinal patterns during range expansions, using forward-time simulations in Nemo. Initial results show, in the absence of prior population structure, range expansions result in a loss of diversity strongly affected by migration, growth, and carrying capacity. This loss of diversity did not persist to the final generation, corresponding to 10,000 years, indicating clinal patterns are less durable than previously assumed—challenging the utility of clinal patterns …

Biology Faculty Articles

Objectives

Archaeological dental calculus is a rich source of host‐associated biomolecules. Importantly, however, dental calculus is more accurately described as a calcified microbial biofilm than a host tissue. As such, concerns regarding destructive analysis of human remains may not apply as strongly to dental calculus, opening the possibility of obtaining human health and ancestry information from dental calculus in cases where destructive analysis of conventional skeletal remains is not permitted. Here we investigate the preservation of human mitochondrial DNA (mtDNA) in archaeological dental calculus and its potential for full mitochondrial genome (mitogenome) reconstruction in maternal lineage ancestry analysis.

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 Jan 2016

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 …
