Attitudes Toward Transgenic Corn Usage Among Amish & Conservative Mennonite Farmers In Ohio, Scot Long Aug 2022

Attitudes Toward Transgenic Corn Usage Among Amish & Conservative Mennonite Farmers In Ohio, Scot Long

Journal of Amish and Plain Anabaptist Studies

Mass adoption and planting of genetically modified corn are part of the larger industrialized agricultural production system in the United States. Amish and conservative Mennonite farmers in the Holmes County settlement region offer an alternative production system often characterized by lower usage of chemical inputs, greater implementation of crop rotation, and significantly higher usage of hybrid versus GMO field corn. Moreover, the rationale among Amish/Mennonite farmers toward adoption of GMO (based on “convenience”) or rejection of GMO (based on “too many unknowns”) stems both from cultural diffusion of neighboring farms as well as variable need for nonfarm income. This article …


Borders: A Story Of Political Imagination, Miriam Ticktin Jun 2022

Borders: A Story Of Political Imagination, Miriam Ticktin

Publications and Research

This article traces three different political imaginaries about borders, suggesting that the dominant imaginary—the one of border walls, driven by a fear of invasion—is only one way to live in the world. The goal is to make space in our political imaginations to rethink how we live together, including thinking beyond nation-states as containers that keep people in or out. By first showing how the vision of invasion is built and maintained with intersecting transnational technologies and ideologies, I open the way to thinking otherwise. Second, I trace the counterpolitics of borders developed by artists and activists, resisting borders and …


Diet And Nutrition Of Lemurs In The Lean Season, Santiago Cassalett Jun 2022

Diet And Nutrition Of Lemurs In The Lean Season, Santiago Cassalett

Dissertations, Theses, and Capstone Projects

Animals must navigate complex food and nutrient environments that are constantly in flux to obtain the macro and micronutrients necessary for their growth, reproduction, and survival. The nutritional needs of animals also vary over the life course, further complicating the search for adequate foods and the nutrients within them. The hypervariable and unpredictable environment of Madagascar creates a complex nutrient landscape for lemurs in particular because they are subject to large fluctuations in food availability. These fluctuations are thought to create extreme periods of nutritional stress during the dry season (known as the lean season) for lemurs. In response, lemurs …


Genetic Impacts Of Deforestation On Mouse Lemurs, Darice Westphal Jun 2022

Genetic Impacts Of Deforestation On Mouse Lemurs, Darice Westphal

Dissertations, Theses, and Capstone Projects

The impact of deforestation on the genetic structure of mouse lemurs is poorly understood. In this project, I assess deforestation of Madagascar’s terrestrial protected regions, quantify genomic wide genetic variation in two sympatric mouse lemurs, and evaluate the role of landscape structure in genetic relatedness patterns within two sympatric mouse lemur species. Overall deforestation rates across the 98 terrestrial protected areas in Madagascar are increasing, resulting in an average annual deforestation rate of 0.68% per year, with approximately 10,600 km2 lost between 2000 and 2019. In a comparison of relatedness patterns between the sympatric gray mouse lemur (Microcebus …


Large-Herbivore Nemabiomes: Patterns Of Parasite Diversity And Sharing, Georgia C. Titcomb, Johan Pansu, Matthew C. Hutchinson, Kaia J. Tombak, Christina B. Hansen, Christopher C. M. Baker, Tyler R. Kartzinel, Robert M. Pringle May 2022

Large-Herbivore Nemabiomes: Patterns Of Parasite Diversity And Sharing, Georgia C. Titcomb, Johan Pansu, Matthew C. Hutchinson, Kaia J. Tombak, Christina B. Hansen, Christopher C. M. Baker, Tyler R. Kartzinel, Robert M. Pringle

Publications and Research

Amidst global shifts in the distribution and abundance of wildlife and livestock, we have only a rudimentary understanding of ungulate parasite communities and parasite-sharing patterns. We used qPCR and DNA metabarcoding of fecal samples to characterize gastrointestinal nematode (Strongylida) community composition and sharing among 17 sympatric species of wild and domestic large mammalian herbivore in central Kenya. We tested a suite of hypothesis-driven predictions about the role of host traits and phylogenetic relatedness in describing parasite infections. Host species identity explained 27 – 53% of individual variation in parasite prevalence, richness, community composition and phylogenetic diversity. Host and parasite phylogenies …


Assessing The Utility Of The Pmm And Mmc Indices Among Extant Hominoid Genera, Julie A. Strain May 2022

Assessing The Utility Of The Pmm And Mmc Indices Among Extant Hominoid Genera, Julie A. Strain

Theses and Dissertations

This thesis set out to incorporate extant hominoid genera into an analysis of PMM and MMC to assess utility in phylogeny and predicting known taxonomic groups. Based on previous claims, we expect PMM/pmm and MMC/mmc to perform better than M1/m1 shape and size, our baseline for success, but they do not.


Investigating The Mechanics And Chemistry Of Sickle Polish Development, Justin Jared Dubois May 2022

Investigating The Mechanics And Chemistry Of Sickle Polish Development, Justin Jared Dubois

Graduate Theses and Dissertations

This series of experiments is designed to understand the development and chemistry of sickle gloss. Sickles are common in the archaeological record and have long been studied for their eponymous “sickle gloss”. There is debate as to how this gloss is formed. Five experimental sickles containing flint and novaculite blades were used to harvest high and low moisture content rye and common fescue and associated field weeds. The differences in the development of sickle gloss were examined. High moisture content plants create thick, smooth fields of polish with undulating, billowing margins at a higher developmental speed. Low moisture content plants …


Quantification Of Dental Fissures Through Occlusal Topography Analysis, Duru Erkan May 2022

Quantification Of Dental Fissures Through Occlusal Topography Analysis, Duru Erkan

Biological Sciences Undergraduate Honors Theses

Narrow, deep, and elaborate dental fissures are widely believed to increase the predisposition of enamel to develop carious lesions as these surfaces are thought to be ideal for cariogenic bacteria to adhere to. Therefore, dentists prescribe sealants as a preventative measure for patients with such fissures to avoid tooth decay. Yet to date, there is no objective data supporting the notion that fissure morphology actually affects caries susceptibility, nor is there a quantifiable, clinically practical method to characterize fissure patterns expected to increase risk of caries disease.

In this study, three new methods to quantitatively characterize fissure pattern in mandibular …


Alfred Russel Wallace Notes 21: Wallace & The Doorway To The Universe, Charles H. Smith May 2022

Alfred Russel Wallace Notes 21: Wallace & The Doorway To The Universe, Charles H. Smith

Faculty/Staff Personal Papers

An important yet largely unrecognized theme in the thought of Alfred Russel Wallace (1823−1913) was his insistence that all dependably-reported phenomena, even those of aberrant nature, were worthy of a respectful kind of attention: that is, a kind which did not automatically banish difficult subjects to the realm of myth or superstition. In this work, Wallace’s philosophy in this direction is documented, and linked to the world of post-Age-of-Enlightenment revisionism.


Reconstructing Bison And Mammoth Migration During The Late Pleistocene And Early Holocene Of Central Texas Using Strontium Isotopes, Joshua John Porter May 2022

Reconstructing Bison And Mammoth Migration During The Late Pleistocene And Early Holocene Of Central Texas Using Strontium Isotopes, Joshua John Porter

Graduate Theses and Dissertations

During the Late Pleistocene (LP; past 130,000 years), over two-thirds of large mammal (>45kg) species went extinct globally. While the role of humans is hotly debated, the effect of these extinctions is growing clearer; the extinctions resulted in widespread and lasting faunal community reorganization. However, the impact of these extinctions on dietary and migratory behavior within faunal communities is unknown. Our study examines the impact of the megafaunal extinctions on the dietary and migratory behavior of surviving Bison individuals in Texas using carbon, oxygen, and strontium isotopes. Strontium isotopes are incorporated into mammalian enamel during their tooth development and …

Making Forests, Making Communities: An Ethnography Of Reforestation In Monteverde, Costa Rica, Megan Brown Apr 2022

Making Forests, Making Communities: An Ethnography Of Reforestation In Monteverde, Costa Rica, Megan Brown

Anthropology Theses and Dissertations

Reforestation is not just planting trees in the ground. More than net increase in forest cover, reforestation is a complex political endeavor undertaken by both humans and non-humans and a popular climate change mitigation tactic. However, little research has examined the dynamics between selection of specific reforestation strategies, health, and community resilience, particularly with attention to entanglements between the lives of both human and non-human forest dwellers. This ethnographic work, based on six months of in-person fieldwork and six months of digital ethnography, examines reforestation and forest relations in Costa Rica’s Monte Verde zone, a region which experienced widespread deforestation, …

Restoring Dignity In The Gardens Of Ekhenana, Jordan Buser Apr 2022

Restoring Dignity In The Gardens Of Ekhenana, Jordan Buser

Independent Study Project (ISP) Collection

This case study investigates the lived experiences of eKhenana, a shack settlement under the leadership of Abahlali baseMjondolo, as they attempt to navigate the increasingly unequal urban landscape. The research presented is focused on theories of urban marginality, food sovereignty, and dignity. I advocate that, in the margins, dignity can be restored through the implementation of a communal garden. Presented as a case study, this research centers the voices and experiences of the commune. The paper first depicts a brief timeline of eKhenana, and explains how they have created not just a place to live, but a community and a …


3d Library From Body Size From Unconventional Specimens: A 3d Geometric Morphometrics Approach To Fishes From Ancestral Pueblo Contexts, Jonathan Dombrosky, Thomas F. Turner, Alexandra Harris, Emily Lena Jones Apr 2022

3d Library From Body Size From Unconventional Specimens: A 3d Geometric Morphometrics Approach To Fishes From Ancestral Pueblo Contexts, Jonathan Dombrosky, Thomas F. Turner, Alexandra Harris, Emily Lena Jones

Anthropology Faculty & Staff Publications

Animal body size estimation from zooarchaeological specimens often relies on specific, one-dimensional (i.e., conventional) measures from skeletal elements. Here, we introduce an animal body size estimation technique for archaeological fishes that relies on 3D reference scans and the calculation of centroid size, a standard 3D geometric morphometric proxy measure for organism size. Centroid size-based estimations on whole caudal vertebrae are strongly correlated with a widely accepted measure (i.e., centrum width), but the scalability and flexibility of the centroid size-based approach allows for use on a wide variety of fragmented remains. We use zooarchaeological fish remains (subfamily Ictiobinae) from late pre-Hispanic …

Rethinking Public Health Risk Mitigation Strategies: Recognizing The Biosocial Nature Of Covid-19, Grace Savard

CSB and SJU Distinguished Thesis

The SARS-CoV-2 virus has rippled throughout every aspect of society and influenced how we live, breathe, and interact with one another. The purpose of this thesis is to explore the interdisciplinary biosocial impacts of the SARS-CoV-2 virus and the resulting disease, COVID-19. In order to understand the complexities of caregiving during COVID-19, we conducted 75 semi-structured interviews with 55 healthcare providers across 18 states over a span of two years. This research assesses how COVID-19 risk mitigation strategies were designed with the primary intention to stop the spread of the virus rather than account for the longer-term social and biological …


Divergent Water Requirements Partition Exposure Risk To Parasites In Wild Equids, Kaia J. Tombak, Laurel A. Easterling, Lindsay Martinez, Monica S. Seng, Liana F. Wait, Daniel I. Rubenstein Mar 2022

Divergent Water Requirements Partition Exposure Risk To Parasites In Wild Equids, Kaia J. Tombak, Laurel A. Easterling, Lindsay Martinez, Monica S. Seng, Liana F. Wait, Daniel I. Rubenstein

Publications and Research

For grazing herbivores, dung density in feeding areas is an important determinant of exposure risk to fecal- orally transmitted parasites. When host species share the same parasite species, a nonrandom distribution of their cumulative dung density and/or nonrandom ranging and feeding behavior may skew exposure risk and the relative selection pressure parasites impose on each host. The arid-adapted Grevy's zebra ( Equus grevyi ) can range more widely than the water-dependent plains zebra ( Equus quagga ), with which it shares the same species of gastrointestinal nematodes. We studied how the spatial distribution of zebra dung relates to ranging and …

The oral cavity is a heterogeneous environment, varying in factors such as pH, oxygen levels, and salivary flow. These factors affect the microbial community composition and distribution of species in dental plaque, but it is not known how well these patterns are reflected in archaeological dental calculus. In most archaeological studies, a single sample of dental calculus is studied per individual and is assumed to represent the entire oral cavity. However, it is not known if this sampling strategy introduces biases into studies of the ancient oral microbiome. Here, we present the results of a shotgun metagenomic study of a …

Invited Perspective - Nutritional Needs And Implications For Children In Subsistence Marketplaces, Nagendra Rangavajla Jan 2022

Invited Perspective - Nutritional Needs And Implications For Children In Subsistence Marketplaces, Nagendra Rangavajla

Subsistence Marketplaces

Today, while the number of stunted children is decreasing in all geographies, the progress is not consistent. Moreover, there is an increasing prevalence of overweight and obesity among children and adolescent. Globally, about half of all children under five do not receive essential nutrients, often unnoticed until too late. On the other end of the spectrum, the incidence of overweight and obesity in 5-19 year old has increased from 4% in 1975 to 18% in 2016 1. These trends reflect a ‘triple burden of malnutrition’, a burden that impacts the survival, growth, and development of children, and in turn, …


The Naming Of Homo Bodoensis By Roksandic And Colleagues Does Not Resolve Issues Surrounding Middle Pleistocene Human Evolution, Eric Delson, Chris Stringer Jan 2022

The Naming Of Homo Bodoensis By Roksandic And Colleagues Does Not Resolve Issues Surrounding Middle Pleistocene Human Evolution, Eric Delson, Chris Stringer

Publications and Research

Roksandic et al. (2022) proposed the new species name Homo bodoensis as a replacement name for Homo rhodesiensis Woodward, 1921, because they felt it was poorly and variably defined and was linked to sociopolitical baggage. However, the International Code of Zoological Nomenclature includes regulations on how and when such name changes are allowed, and Roksandic et al.'s arguments meet none of these requirements. It is not permitted to change a name solely because of variable (or erroneous) later use once it has been originally defined correctly, nor can a name be modified because it is offensive to one or more …


The Question Is Not “Can Humans Talk?” Or “Can They Suffer?” But “Can They Reason?”, Clive Phillips Jan 2022

The Question Is Not “Can Humans Talk?” Or “Can They Suffer?” But “Can They Reason?”, Clive Phillips

Animal Sentience

In their target article, Rowan et al (2022) make a welcome attempt to chart the development of Western progress over the past two hundred years toward formally recognizing that animals feel. They outline the heroic efforts of Compassion in World Farming to gain for animals the status of sentient beings rather than merely human property. A broader view exists, from human prehistory to the present day, in which animals have been (and still are) understood to be sentient by indigenous peoples as well as by some Eastern religions. Growing recognition in the West that animals feel represents a new age …


Wilderness And The Geotag: Exploring The Claim That "Geotagging Ruins Nature" In The Alpine Lakes Wilderness, Wa, Mara Gans Jan 2022

Wilderness And The Geotag: Exploring The Claim That "Geotagging Ruins Nature" In The Alpine Lakes Wilderness, Wa, Mara Gans

All Master's Theses

This research explores the claim that “geotagging ruins nature” by quantifying and qualifying patterns in geotag use and visitors’ experiences in the Alpine Lakes Wilderness, in Washington, United States. Many have raised concerns that geotags increase recreational visitation to public lands, which subsequently contributes to negative resource impacts. Others, however, claim that geotagging has made the outdoors more accessible to less privileged communities and raise concerns that condemning geotags will perpetuate the exclusion of certain groups from outdoor recreation. This debate is studied within federally designated Wilderness, which is legally defined as “untrammeled by man,” a definition rooted in problematic …

Death Scene Insect Succession In Nebraska: A Guidebook, Erin Bauer, Larry Barksdale, Emma Sidel, Justine Laviolette

Department of Entomology: Faculty Publications

Insect behavior can be helpful to law enforcement in determining time of death, manner of death, location, and environment related to human or other animal victims found at a death scene. They may also provide clues about other aspects associated with an investigation (i.e., fly specks, suspect DNA). The study of how insects and related arthropods can aid in legal investigations is known as forensic entomology. Although this includes both civil applications, such as urban (i.e., maggots in mortuaries or insect structural damage) or stored product (i.e., illness from food contamination) entomology, this manual focuses on criminal applications, such as …


Energetic Tradeoffs, Infection, And Immunity In Wild Chimpanzees Of Uganda And Tanzania, Sarah Renee Phillips Dec 2021

Energetic Tradeoffs, Infection, And Immunity In Wild Chimpanzees Of Uganda And Tanzania, Sarah Renee Phillips

Anthropology ETDs

Infectious disease is a primary source of mortality for most mammal species, but scientists have little understanding of factors driving variation in infection and immunity between individuals, populations, and species in the wild. Life history theory provides an evolutionary framework for delineating distribution of available energy to competing physiological demands, including growth, reproduction, and maintenance. Early life reproduction should be favored over late life survival, but, in long-lived species, reproductive success is strongly tied to survival to old age. Slower pace of reproduction could allow investment in immunity, reducing risk of morbidity and mortality to infectious disease. Additionally, several host …


Canine Microwear In Relation To Diet In Sumatran Primates And African Great Apes, Putu Pujiantari Dec 2021

Canine Microwear In Relation To Diet In Sumatran Primates And African Great Apes, Putu Pujiantari

Graduate Theses and Dissertations

This thesis considers canine microwear in relation to diet in five Sumatran primates (Pongo abelii, Hylobates lar, Hylobates agilis, Presbytis thomasi, and Macaca fascicularis) and two African great apes (Pan paniscus and Pan troglodytes schweinfurthii) using both microwear texture analysis and microwear feature analysis techniques. Statistical results for texture analysis show that there are significant differences in scale of maximum and heterogeneity. This indicates that some species have large pits on their canine surfaces, having these dominated by deep features at coarse scale yet have a slight microwear heterogeneity. For feature analysis, all variables show statistically significant variation. Variance in …
