Annotation Of Non-Model Species’ Genomes, Taiya Jarva 2023 The University of Southern Mississippi

Annotation Of Non-Model Species’ Genomes, Taiya Jarva

Master's Theses

The innovations in high throughput sequencing technologies in recent decades has allowed unprecedented examination and characterization of the genetic make-up of both model and non-model species, which has led to a surge in the use of genomics in fields which were previously considered unfeasible. These advances have greatly expanded the realm of possibilities in the fields of ecology and conservation. It is now possible to the identification of large cohorts of genetic markers, including single nucleotide polymorphisms (SNPs) and larger structural variants, as well as signatures of selection and local adaptation. Markers can be used to identify species, define population …

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer 2023 Southern Methodist University

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …


Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino 2023 Eastern Washington University

Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino

2023 Symposium

The Schlepp Easement is a 400 acre wetland on the Coeur D’Alene River floodplain, near Cataldo, Idaho. The wetland has been restored to protect it from heavy metal pollution transported downstream from mining sites near Kellogg, Idaho, the location of the Bunker Hill EPA Superfund Site. This wetland was restored to provide safe habitats and feeding grounds for migratory waterfowl and to maintain wetland biodiversity. However, cattail is prone to becoming overdominant and outcompeting other plants, which greatly limits a wetland’s biodiversity. Our objectives were to test whether aquatic boat mowing can reduce cattail cover, improving species diversity and cover …


Legacy Effects Of Forest Clearcutting On Ecosystem Function And Biogeochemical Cycling In A New England Forest, Andre Solomon Gomes 2023 Rhode Island College

Legacy Effects Of Forest Clearcutting On Ecosystem Function And Biogeochemical Cycling In A New England Forest, Andre Solomon Gomes

Honors Projects Overview

Terrestrial soils comprise the largest reservoirs of carbon (C) in the biosphere holding some 2500 Gt C, which is 4x the amount found in plant biomass and 3x the C content of the atmospheric pool. Approximately 1500 Gt of soil C is in an organic form, thus making it available to mineralization by heterotrophic organisms [10]. Changes to the drivers of mineralization such as climate change and aeration due to anthropogenic land use, such as logging, have the potential to strongly affect global carbon and associated nutrient cycles, plant production, and atmospheric composition. With the aim of better understanding the …


Aspects Of Distribution, Abundance, Habitat, And Life History Of The Caddo Madtom (Noturus Taylori), A Narrow Endemic Of The Ouachita Highlands, Brittany L. McCall, Brook L. Fluker 2023 Arkansas State University, Environmental Sciences Program

Aspects Of Distribution, Abundance, Habitat, And Life History Of The Caddo Madtom (Noturus Taylori), A Narrow Endemic Of The Ouachita Highlands, Brittany L. Mccall, Brook L. Fluker

Southeastern Fishes Council Proceedings

The Caddo Madtom, Noturus taylori, is a small catfish endemic to the Ouachita Mountain ecoregion in Arkansas, with habitat altered by land use practices and reservoir dams. We examined aspects of distribution, abundance, habitat, and life history of N. taylori during seasonal sampling from winter 2016 through fall 2017. Our sampling data were concordant with previous studies that suggested N. taylori is more widespread and has higher catch per unit effort in the Caddo River drainage when compared to the upper Ouachita River drainage. We did not detect N. taylori in the Little Missouri River drainage, where it is …


Mutual Aid: The Other Law Of The Jungle. Gauthier Chapelle And Pablo Servigne. Cambridge, Polity Press. 2022. 310 Pp, Tom P. Flower Dr 2023 Capilano University

Mutual Aid: The Other Law Of The Jungle. Gauthier Chapelle And Pablo Servigne. Cambridge, Polity Press. 2022. 310 Pp, Tom P. Flower Dr

Emancipations: A Journal of Critical Social Analysis

In 1902, the anarchist Peter Kropotkin published Mutual Aid in which he promoted a radical perspective on evolution in which cooperation, as well as selfishness, drive the form, diversification and organization of life on earth. Despite initial recognition, Kropotkin’s contributions have been largely forgotten, even as modern evolutionary theory has recognized the central role of cooperation. In Mutual Aid: the other law of the jungle, Pablo Servigne and Gauthier Chappelle restore Kropotkin’s insights to their rightful place as foundational for our understanding of evolution. They further seek to overturn the pernicious misconception of the 20th century, that nature is …


Meiofauna Distribution Patterns On A Sandy Beach Of Sapelo Island, Georgia, Nancy Dalman 2023 University of North Georgia

Meiofauna Distribution Patterns On A Sandy Beach Of Sapelo Island, Georgia, Nancy Dalman

Georgia Journal of Science

Substantial abundance and diversity of intertidal invertebrates known as meiofauna are evident on a sandy beach of Sapelo Island, Georgia. Meiofauna are small, benthic, nearly ubiquitous animals. They consume microbes and detritus and are a food source for juvenile fish and ghost shrimp. Meiofauna were manually separated from sand samples collected from three intertidal zones and two depths during low tide in January, March, June, and October, 2017. Fifteen major meiofaunal clades were identified in June, while only eight were observed in January; in all, there were sixteen clades observed. Highest meiofauna densities were found in the middle intertidal zone …


A Small-Scale Wave Tank For Living Shoreline Extension And Outreach, Keith Chenier Jr, Jaden Akers, Skylar Liner, Shelby Harrier, Eric Sparks, Patrick Biber, Laura Blackmon, Jessica Kastler, Patrick Broussard 2023 Mississippi State University

A Small-Scale Wave Tank For Living Shoreline Extension And Outreach, Keith Chenier Jr, Jaden Akers, Skylar Liner, Shelby Harrier, Eric Sparks, Patrick Biber, Laura Blackmon, Jessica Kastler, Patrick Broussard

The Journal of Extension

Hardened structures, such as bulkheads and seawalls, are currently the primary choice of shoreline protection for waterfront property owners. However, hardened shorelines are known to enhance erosion and often promote the loss of intertidal habitat. Living shorelines are a collection of environmentally friendly construction techniques that serve as an alternative to hardened shorelines through the incorporation of natural materials, such as native plants. To enhance extension and outreach efforts related to the promotion of living shorelines, we created a small-scale, hands-on wave tank that demonstrates the benefits of natural and living shorelines relative to hardened structures. This interactive tool allows …


Vibroacoustic Response Of The Tympanic Membrane To Hyoid-Borne Sound Generated During Echolocation In Bats, Chelsie Snipes 2023 East Tennessee State University

Vibroacoustic Response Of The Tympanic Membrane To Hyoid-Borne Sound Generated During Echolocation In Bats, Chelsie Snipes

Electronic Theses and Dissertations

The hyoid apparatus in laryngeally echolocating bats forms a mechanical connection between the larynx and auditory bullae and has been hypothesized to transfer the outgoing echolocation call to the middle ear during echolocation call emission. We used µCT data to build models of the hyoid apparatus and middle ear from six species of bats and used finite element modeling (FEM) to measure the vibroacoustic response of the tympanic membrane due to hyoid-borne sound generated during echolocation. We found that hyoid-borne sound in all six species stimulated the eardrum within a range likely heard by bats. Although there were minor differences …


Regeneration Of Quaking Aspen And Understory Vegetation Change After Fire Risk Reduction Treatment, Allison M. Trudgeon 2023 Utah State University

Regeneration Of Quaking Aspen And Understory Vegetation Change After Fire Risk Reduction Treatment, Allison M. Trudgeon

All Graduate Theses and Dissertations

Quaking aspen (Populus tremuloides Michx.) is a keystone species that, when coexisting with conifers (i.e., seral aspen), often undergoes stand-replacing disturbances to sustain long term vigor. Historically, mixed-to-high severity fire reduced fuels and regenerated aspen, but such disturbances have become less common in recent decades. This has often led to high fuel loading, and many seral aspen stands are at now risk of an unpredictable, high-severity fire, posing a threat to development in the wildland-urban-interface. The lack of a commercial market for aspen, and the risk of conducting prescribed fire, means there are few alternate management options. This has …


The Barriers To Movement: The Effects Of Anthropogenic Linear Features On The Space-Use Behaviors Of Mule Deer And Pronghorn In Utah, Ronan B. Hart 2023 Utah State University

The Barriers To Movement: The Effects Of Anthropogenic Linear Features On The Space-Use Behaviors Of Mule Deer And Pronghorn In Utah, Ronan B. Hart

All Graduate Theses and Dissertations

Human development of structures like roads, fences, and other linear features can make it difficult for animals to move around their environment, affecting their ability to find food and avoid danger. Animal movement and the way they use space comes about from their responses to their surroundings and their choices to balance risk and reward. Because of this, we can understand how roads and fences affect wildlife by studying the way they move around their habitats. In this thesis, I focused on two large herbivores, mule deer and pronghorn, and studied how they use the space within Utah, United States …


Fractally Sampling Diversity-Environment Relationships To Understand Plant Assemblage Health Across Spatial Scales, Elizabeth G. Simpson 2023 Utah State University

Fractally Sampling Diversity-Environment Relationships To Understand Plant Assemblage Health Across Spatial Scales, Elizabeth G. Simpson

All Graduate Theses and Dissertations

Humans influence the health of ecosystems and rely on healthy ecosystems to support their livelihoods and well-being. By looking at how the parts of ecosystems interact we can understand and improve ecosystem health. Ecosystem interactions change across spatial scales or different size patches of area. For example, individual organisms interact with each other at small spatial scales, while at large spatial scales, communities of organisms interact with weather conditions. However, many research studies do not look at how ecosystem interactions change across spatial scales. To address this gap in ecological research, I use a fractal sampling design which samples at …


Local And Regional Landscape Characteristics Driving Habitat Selection By Greater Sage-Grouse Along A Fragmented Range Margin, Aidan T. Beers 2023 Utah State University

Local And Regional Landscape Characteristics Driving Habitat Selection By Greater Sage-Grouse Along A Fragmented Range Margin, Aidan T. Beers

All Graduate Theses and Dissertations

In response to ongoing landscape change, wildlife species are likely to respond in varied ways. By studying habitat specialists, we are able to better understand the most likely ways in which the denizens of threatened ecosystems will react to those changes. Among the most threatened ecosystem types in North America are sagebrush ecosystems of the Intermountain West, where one of its most well-known residents, greater sage grouse (hereafter, “sage-grouse), have lost more than 50% of their habitat due to fire, invasive species, climate change, encroachment by coniferous forests and avian predators using it, and human-caused landscape conversion. Sage-grouse rely on …


Evaluating Methods For Pathogen Spillover Detection And Forecasting In Desert Bighorn Sheep (Ovis Canadensis Nelsoni), Grete E. Wilson-Henjum 2023 Utah State University

Evaluating Methods For Pathogen Spillover Detection And Forecasting In Desert Bighorn Sheep (Ovis Canadensis Nelsoni), Grete E. Wilson-Henjum

All Graduate Theses and Dissertations

Managers mitigate the effects of disease on wildlife populations by detecting outbreaks and predicting disease transmission. Bighorn sheep (Ovis canadensis) populations face threat from the introduced pathogen Mycoplasma ovipneumoniae (M. ovipneumoniae). In the eastern Mojave Desert, managers detect pathogen outbreaks in desert bighorn (O. c. nelsoni) through aerial population surveys, which produce irregular and coarse population information. Furthermore, managers model the risk of M. ovipneumoniae transmission amongst desert bighorn populations, however these models assume that desert bighorn space use is unchanging across years. Here, I evaluate methods used by managers to detect disease outbreaks …


The Scaling Method: Body Mass Reconstruction Of East African Hominins, Julianna Rose 2023 University of Arkansas, Fayetteville

The Scaling Method: Body Mass Reconstruction Of East African Hominins, Julianna Rose

Anthropology Undergraduate Honors Theses

This thesis details a series of novel methods developed to estimate body masses of hominin fossils using 3-D point cloud registration software. All analyses were conducted through 3-D modeling software that supported the remote study of five fossil femora from East Africa. The fossil computer models were repeatedly aligned with anatomically modern human femora to determine their scaling relationship with the objective of using the scaling factor of the human references to estimate the body mass of the fossils, on the basis of the femoral head breadth. Body mass estimates obtained through this technique were compared to estimates using more …
