Identification Of Whole Mitochondrial Genomes From Venezuela And Implications On Regional Phylogenies In South America, Esther J. Lee, D. Andrew Merriwether

Human Biology Open Access Pre-Prints

Recent studies have expanded and refined the founding haplogroups of the Americas using whole mitochondrial (mtDNA) genome analysis. In addition to pan-American lineages, a number of studies have identified specific variants that show higher frequencies in restricted geographical areas. In order to further characterize Native American maternal lineages and specifically examine local patterns within South America, we analyzed twelve maternally unrelated Yekuana whole mtDNA genomes from one village (Sharamaña) that include the four major Native American haplogroups A2, B2, C1, and D1. Our study proposes a reconfiguration of one subhaplogroup A2 (A2aa) that is specific to South America and identifies …

Evaluation Of Desiccated And Deformed Diaspores From Natural Building Materials, Tamas Henn, Robert Pal

Biological Sciences

With the increasing sophistication of paleoethnobotanical methods, it is now possible to reconstruct new aspects of the day-to-day life of past peoples, and, ultimately, gain information about their cultivated plants, land-use practices, architecture, diet, and trade. Reliable identification of plant remains, however, remains essential to the study of paleoethno-botany, and there is still much to learn about precise identification. This paper describes and evaluates the most frequent types of deformed desiccated diaspores revealed from adobe bricks used in buildings in Southwestern Hungary that were built primarily between 1850 and 1950. A total of 24,634 diaspores were recovered from 333.05 kg …

Was There A Sensory Trade-Off In Primate Evolution? The Vomeronasal Groove As A Means Of Understanding The Vomeronasal System In The Fossil Record., Eva Christine Garrett

Dissertations, Theses, and Capstone Projects

Primates have remarkable visual adaptations compared to most other mammals, long explained as associated with a trade-off with olfaction (smell). However, as more information comes to light on the role of olfaction in primate behavior it becomes apparent that olfaction is not a trivial sense. Even humans use smell to communicate, albeit in subtle ways, and the olfactory systems of the lemurs and lorises are very well-developed. Olfaction, however, is actually comprised of two distinct systems - the main olfactory and vomeronasal systems. These two systems overlap in many functions, but the main olfactory system is considered fairly generalized while …

Subsistence Strategies In Traditional Societies Distinguish Gut Microbiomes, Alexandra J. Obregon-Tito, Raul T. Tito, Jessica Metcalf, Krithvivasa Sankaranarayanan, Jose C. Clemente, Luke K. Ursell, Zhenjiang Zech Xu, Will Van Treuren, Rob Knight, Morris Foster

Division of Research and Economic Development Faculty & Staff Publications

Recent studies suggest that gut microbiomes of urban-industrialized societies are different from those of traditional peoples. Here we examine the relationship between lifeways and gut microbiota through taxonomic and functional potential characterization of faecal samples from hunter-gatherer and traditional agriculturalist communities in Peru and an urban-industrialized community from the US. We find that in addition to taxonomic and metabolic differences between urban and traditional lifestyles, hunter-gatherers form a distinct sub-group among traditional peoples. As observed in previous studies, we find that Treponema are characteristic of traditional gut microbiomes. Moreover, through genome reconstruction (2.2-2.5 MB, coverage depth x26-513) and functional potential …

A Decade Of Advances In The Paleopathology Of The Ancient Egyptians, Lisa Sabbahy Dr.

Faculty Book Chapters

Although the bioarchaeology (study of biological remains in an archaeological context) of Egypt has been documented in a desultory way for many decades, it is only recently that it has become an inherent part of excavations in Egypt. This volume consists of a series of essays that explore how ancient plant, animal, and human remains should be studied, and how, when they are integrated with texts, images, and artefacts, they can contribute to our understanding of the history, environment, and culture of ancient Egypt in a holistic manner.

Topics covered in this volume relating to human remains include analyses of …

Controversy In Skeletal Biology: The Use Of Pathological And Osteological Markers As Evidence For Activity Patterns, Anna Alioto

The Hilltop Review

One of the most pressing controversies today within a multitude of disciplines in biological anthropology including bioarchaeology, paleoanthropology and especially skeletal biology is whether or not physical activity patterns of individuals can be inferred from skeletal material and what types of activities can be reconstructed from that data (Jurmain et al., 2011). While many authors have published articles that incorporated the use of pathological and osteological markers as evidence for activity patterns, there is still much dispute within the skeletal biological community on the validity and the accuracy of the techniques used. This paper will discuss what types of markers …

Human Feeding Biomechanics : Intraspecific Variation And Evolution, Justin Ledogar

Legacy Theses & Dissertations (2009 - 2024)

This study examines feeding biomechanics in modern human crania and those of extinct early members of the human lineage in order to better understand the selective pressures that influenced human craniofacial evolution. Specifically, this study uses finite element analysis to examine: 1) human feeding performance, in terms bite force production and craniofacial strength; 2) intraspecific variation in human feeding biomechanics; 3) feeding biomechanics in fossil hominins, including Australopithecus sediba and Homo habilis, species that are potentially at the root of modern human lineage, and 4) the functional role of purported facial buttresses.

Antibiotics, The Microbiome, And Immunity : A Case Study In Bangladesh, Carmen Fagnani

Legacy Theses & Dissertations (2009 - 2024)

The purpose of this study was to establish a theoretical impact of antibiotic misuse on the microbiome and its effects on immunity. Recent studies indicate the importance of a microbiome on the immune system. Both the leptin signaling pathways and CD4T cell production are influenced by the microbiome (Mazmanian, et al. 2005). The use of antibiotics has been associated with dysbiosis, a microbial imbalance in the digestive tract. The immune system is limited when the microbiome is dysbiotic.

Examining The Craniofacial Biomechanics Of Paranthropus Boisei, Amanda L. Smith

Legacy Theses & Dissertations (2009 - 2024)

An engineering method, finite element analysis (FEA), was used to examine the craniofacial biomechanics of Paranthropus boisei. The craniofacial morphology of Paranthropus boisei exhibits a number of highly derived characteristics that have commonly been thought to be related to feeding. This series of studies includes an ex vivo strain gage study (validation of techniques), an assessment of the effects of intraspecific craniofacial shape variation in chimpanzees (Pan troglodytes), and an examination of the feeding biomechanics of Paranthropus boisei. Modeling experiments were also conducted to test mechanical hypotheses regarding the effects of specific derived craniofacial features on Paranthropus feeding function.

The Biomechanical And Behavioral Significance Of The Neanderthal Femur, Kelli Hamm Tamvada

Legacy Theses & Dissertations (2009 - 2024)

The Neanderthal (Homo neanderthalensis) femur is distinct from that of recent modern humans (Homo sapiens). Broadly speaking, the Neanderthal femur is more "robust", meaning that it appears to be biomechanically stronger, and it is more curved, which may enhance the predictability of the stresses and strains experienced by the bone. It has been hypothesized that the Neanderthal morphology is an adaptation to withstand elevated and repetitive loads associated with increased mobility. This study tests the mobility hypothesis using comparative and biomechanical methods. Specifically, this study sought to test the mobility hypothesis by a) determining whether or not a relationship exists …

Female Social Connectivity Through The Leadership And Movement Progression Of Tibetan Macaques At Mt. Huangshan, China, Gregory P. Fratellone

All Master's Theses

The present study investigates the leadership and progression of collective movements of Tibetan macaques (Macaca thibetana) found in Mt. Huangshan, China. I gathered information on their movements and social networks through all-occurrence, focal and scan sampling. I hypothesize that high-ranking females lead more collective movements than males as they have highly structured social bonds. I also predict that movements weighted by female presence are more efficient as societies are matrilineally structured and females are more socially connected. There were a total of 128 successful collective movements recorded over a 2-month period. There was no significant effect of sex, …

Geometric Morphometric Analysis Of Pan Frontal Bone Morphology, Allen J. Myhra

Department of Anthropology: Theses and Student Research

This study employs geometric morphometric methods to investigate the morphology and shape change of the frontal bone for Pan troglodytes and Pan paniscus. Unlike previous work on the topic, this research analyzed morphology and ontogenetic shape change in a single bone of the cranium, namely the frontal bone. Frontal bone shape was compared between juvenile Pan troglodytes and Pan paniscus and the ontogeny of the bone was assessed in Pan paniscus infants and juveniles. Analyses were performed on frontal bone morphology with and without the browridge in order to assess the morphology of the frontal apart from influences …

Multiple Stain Histology Of Skeletal Fractures: Healing And Microtaphonomy, John Wellington Powell

USF Tampa Graduate Theses and Dissertations

The forensic examination of wounds is one of the key elements of analysis performed by forensic anthropologists and forensic pathologists. Gross examination and histological analysis can be used to determine the timing of the wound and its cause. While forensic pathologists are trained to analyze hard and soft tissue wounds, forensic anthropologists, bioarchaeologists, and paleopathologists, focus on hard tissue. Forensic anthropologists have the added benefit of potentially working with residual soft tissue and would benefit from the incorporation of microscopy techniques that take advantage of the soft tissue to better understand perimortem events. Little research has been published that examines …

Javan Gibbon (Hylobates Moloch) Non-Vocal Social Communication And Gesture Use With Conspecifics, Melanie Bell

All Master's Theses

I explored gestures used by captive Javan gibbons (Hylobates moloch) at the Gibbon Conservation Center (Santa Clarita, CA). I hypothesized that a sender gibbon’s gesture modality would vary with the recipient gibbon’s attentional state and the sender would be equally likely to use all modalities (tactile, visual, actions, and facial expressions) when the recipient was attending (facing the sender), but would use more tactile gestures and actions when the recipient was non-attending (oriented away from the sender). I collected data from 10 individuals using all-occurrences sampling and an ethogram to score behaviors from video recordings. In 1,143 interactions, …

A Comparison Of Chimpanzee (Pan Troglodytes) Responses To Caregiver Use Of Positive Reinforcement Training (Prt) And Species-Specific Behaviors (Ssb), Whitney D. Emge

All Master's Theses

The present study compared the effects of positive reinforcement training (PRT) and unstructured interactions (UI) on chimpanzee (Pan troglodytes) behavior. In the PRT condition, a caregiver interacted with a chimpanzee to condition behaviors for 10 min. In the UI condition, a caregiver interacted without PRT for 10 min. Participants were five chimpanzees in a sanctuary setting. Chimpanzees were also videotaped for 10 min after trials (PTP) and for 10 min in a matched control (MC) period on a different day. From these videotapes experimenters coded chimpanzee behaviors and calculated durations in behavioral contexts. Chimpanzees spent a significantly higher …

Provisioning And Its Effects On The Social Interactions Of Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Brianna I. Schnepel

All Master's Theses

The dispersal patterns of food resources has a significant effect on the composition of primate groups and social interactions within those groups. Humans often alter the dispersal of food. Non-humans often use affiliative behaviors to elicit tolerance or support from other group members. I investigated whether provisioned food resources alter the social interactions and group dynamics of Macaca thibetana. All-occurrence sampling and scan sampling were used for data recorded by camera traps. Trail-cameras were placed at six locations that contain natural and human food resources and recorded 60-second videos. Social behavior and proximity of the monkeys were recorded. I …
