Novel Collective Prey Evasion Response Of Pseudomonas Aeruginosa Pao1 To Soil Micropredator Myxococcus Xanthus Dk1622, Joshua Lummus Jul 2023

Novel Collective Prey Evasion Response Of Pseudomonas Aeruginosa Pao1 To Soil Micropredator Myxococcus Xanthus Dk1622, Joshua Lummus

Master of Science in Integrative Biology Theses

The search for alternative therapeutics is on the rise because of the threat of multi-drug resistant bacteria. Looking at the hunting strategy of soil-based bacterial micropredators is one avenue of exploration. Myxobacteria are soil predators with a wide prey range including Gram-negative and Gram-positive bacteria, fungi, and archaea. In our lab we discovered a distinct and novel anti-predation behavior in Pseudomonas aeruginosa strain 01. P. aeruginosa is an opportunistic and nosocomial pathogen responsible for 10% of all hospital acquired infections. P. aeruginosa is also an ESKAPE pathogen, which are leading causes of nosocomial infections throughout the world, and they are …

Microbial Commensals Of Tricolored Bats In Georgia And Their Probiotic Potential, Jordyn Upton Jul 2023

Microbial Commensals Of Tricolored Bats In Georgia And Their Probiotic Potential, Jordyn Upton

Master of Science in Integrative Biology Theses

Pseudogymnoascus destructans (Pd) is a fungal pathogen that has been spreading in North American bats since its initial discovery in 2006. P. destructans is the causative agent of white-nose syndrome (WNS), a disease leading to as much as a 90% decrease in some eastern United States bat populations, with select hibernacula experiencing complete extirpation of the hibernating population. To date, there is no effective scaled probiotic for WNS, but probiotics inoculums have shown success in the management of other recently emerged fungal pathogens of wildlife, such as chytridiomycosis in amphibians. Host microbiomes have come under investigation in other disease systems …

Early Stage Or Curable Cancer Diagnoses In Minorities: A Journey Of Survivors, Lora Asberry Jul 2023

Early Stage Or Curable Cancer Diagnoses In Minorities: A Journey Of Survivors, Lora Asberry

Master of Science in Integrative Biology Theses

Patients diagnosed with early-staged or curable forms of cancer experience physical, as well as, mental challenges associated with disease progression and treatment. Previous studies have demonstrated that minorities and underrepresented communities did not receive the same level of care in comparison to their non-minority counterparts. Previous studies have also demonstrated that health disparities among minorities affected their cancer journey. This study addressed: how medical disparities varied between minorities and non-minorities, the overall effects of the cancer diagnoses in minorities compared to non-minorities, whether these perspectives differed in male vs. female participants, and whether there were any possible communication barriers between …

Testing The Urban Dulling Hypothesis In An Iridescent Passerine Bird, Joanna Gresham Jul 2023

Testing The Urban Dulling Hypothesis In An Iridescent Passerine Bird, Joanna Gresham

Master of Science in Integrative Biology Theses

Urbanization has brought grave consequences that lead to declines in many species; however, some species thrive in urban ecosystems. This allows us the opportunity to study evolution in real time, as species adapt and change in a new setting. Novel urban ecosystems have led to phenotypic divergence between urban and rural populations. There is a rich body of literature on how songbirds are affected by urbanization, however divergent signaling behaviors are less well understood. Urban color homogenization is well-documented in carotenoid-colored species. However, iridescent plumage is understudied in general, and little is understood about how environmental changes shape iridescent plumage. …

Comparing Four Indices Of Physiological Stress In An Urban-Adapted Songbird Between Urban And Rural Habitats, Rachel Kaplan Jul 2023

Comparing Four Indices Of Physiological Stress In An Urban-Adapted Songbird Between Urban And Rural Habitats, Rachel Kaplan

Master of Science in Integrative Biology Theses

Birds show tremendous variation in the extent to which different species tolerate life in urban habitats, yet it remains unclear why some species thrive while others cannot. My work explores possible phenotypes that make an urban-adapted species, the European starling (Sturnus vulgaris), so successful in both rural and urban areas. Literature on stress-urbanization relationship remains highly equivocal partly due to an array of different study systems being compared as well as to key methodological differences. The present study quantified metrics of both acute stress (i.e., stress-induced corticosterone and breath rate) and chronic stress (i.e., baseline corticosterone and total …

Martine, Clara Ines Orozco, Iris E. Peralta, Tina Sarkinen

Faculty Journal Articles

Solanum is one of the world's largest and economically most important plant genera, including 1245 currently accepted species and several major and minor crops (e.g., tomato, potato, brinjal eggplant, scarlet eggplant, Gboma eggplant, lulo, and pepino). Here we provide an overview of the evolution of 25 key morphological traits for the major and minor clades of this giant genus based on stochastic mapping using a well-sampled recently published phylogeny of Solanum. The most evolutionarily labile traits (showing >100 transitions across the genus) relate to plant structure (growth form and sympodial unit structure), herbivore defence (glandular trichomes), pollination (corolla shape …

Influence Of Woody Vegetation Composition And Structure On Fuels And Prescribed Fire In Mountain Longleaf Restoration, Collin J. Anderson Jun 2023

Influence Of Woody Vegetation Composition And Structure On Fuels And Prescribed Fire In Mountain Longleaf Restoration, Collin J. Anderson

Master of Science in Integrative Biology Theses

Longleaf pine (LLP) ecosystems have experienced a widespread ecological state shift largely due to fire exclusion which has allowed mesophytes, i.e., shade-tolerant, often fire-sensitive species to encroach, reducing flammability and biodiversity through a process known as “mesophication.” Although prescribed fire is commonly used to reverse mesophication, fire behavior, and thus prescribed fire utility for this purpose, is poorly characterized in mixed pine-hardwood stands with mesophyte encroachment. This study aimed to identify mechanisms by which tree composition, structure, and fuels contribute to fire behavior, focusing on the understudied mountain longleaf pine (MLLP) ecoregion in northwest Georgia. I hypothesized that woody vegetation …

Variation In Salamander Life History And Community Composition Across An Urban Gradient In Atlanta, Georgia, Usa, Leah Rittenburg Jun 2023

Variation In Salamander Life History And Community Composition Across An Urban Gradient In Atlanta, Georgia, Usa, Leah Rittenburg

Master of Science in Integrative Biology Theses

Urbanization threatens to alter stream systems in watersheds in the eastern United States. These highly disturbed systems may result in many local extirpations of sensitive salamander species. One group of organisms that often persists in urban streams is the Eurycea bislineata (Two-lined Salamander) species complex. Many aspects of Two-lined Salamander life history are linked to environmental factors, particularly stream temperature, prey abundance, and stream hydrology. Urbanization threatens to alter these environmental factors, potentially influencing Two-lined Salamander life history. At 14 sites spanning an urban gradient in Atlanta, GA, I investigated the variation in life history and phenology in the Southern …

First Shasta Ground Sloth (Nothrotheriops; Xenarthra) From The Eastern Great Basin, Nevada, Jim I. Mead, Sandra L. Swift, H. Gregory Mcdonald, Steven D. Emslie Jun 2023

First Shasta Ground Sloth (Nothrotheriops; Xenarthra) From The Eastern Great Basin, Nevada, Jim I. Mead, Sandra L. Swift, H. Gregory Mcdonald, Steven D. Emslie

Western North American Naturalist

We present the first record of the Shasta ground sloth (Nothrotheriops shastensis) for the eastern Great Basin. The single right upper second molariform was recovered from the back dirt pile of archaeological test pits excavated during the 1960s and 1970s in Smith Creek Cave, northern Snake Range, White Pine County, Nevada. The precise age of the specimen is indeterminate, although all sediment layers in the area produced radiocarbon dates older than 11,000 cal BP; thus, the specimen is considered of the Rancholabrean Land Mammal Age. All previous accounts of this sloth in the Great Basin are from its …

Plains To Peaks: An Analysis Of The Relationship Between Colorado Butterfly Communities And Altitude, Anna O. James, Kathryn Hokamp, Chris García-Hellmuth, Richard P. Reading Jun 2023

Plains To Peaks: An Analysis Of The Relationship Between Colorado Butterfly Communities And Altitude, Anna O. James, Kathryn Hokamp, Chris García-Hellmuth, Richard P. Reading

Western North American Naturalist

We compared butterfly communities of the Plains, Foothills, and Montane Zones of the Colorado Front Range and examined 3 groups of butterflies—blues (Polyommatinae species), fritillaries (Speyeria and Boloria spp.), and painted ladies (species Vanessa cardui)—for altitude shifts between 2014 and 2020. We conducted these analyses using data collected by volunteer butterfly monitors from the Colorado Butterfly Monitoring Network, a group organized and run by Butterfly Pavilion in Westminster, Colorado. Monitors walked designated routes and counted all butterflies they saw, identifying each to the lowest possible taxonomic group they could. We sorted routes into the 3 altitude zones, organized …

The Manhattant: Identification, Natural History, And Nutritional Ecology Of A Recently Introduced Pest In New York City, Lasius Emarginatus (Hymenoptera: Formicidae), Samantha Kennett

Master of Science in Integrative Biology Theses

New York City is one of the oldest and largest cities in North America, and it is a center for global trade and shipping. As such, it has also been the site of introduction for some of North America’s most damaging invasive pests, from chestnut blight to the Asian long-horned beetle. Despite these cautionary examples, there has been no formal research on a newly introduced ant species that was tentatively identified as a European ant species, Lasius cf. emarginatus. Since its discovery in 2011, L. cf. emarginatus has become among the most common urban ant species in New York …

The Polycomb Complex 2 Contributes To Developmental Delay When Histone Methylation Is Inappropriately Inherited, Sydney Morgan- Benitez Jun 2023

The Polycomb Complex 2 Contributes To Developmental Delay When Histone Methylation Is Inappropriately Inherited, Sydney Morgan- Benitez

Master of Science in Integrative Biology Theses

Histone methylation is a post-transcriptional modification to the N-terminal tails of histone core proteins that regulates DNA accessibility, and consequently, gene expression. Like DNA, histone methylation can be inherited between generations, and is highly regulated during embryonic development. At fertilization, histone methylation must undergo maternal reprogramming to reset the epigenetic landscape in the new zygote. During maternal reprogramming of histone methylation in C. elegans, H3K4me is removed by the H3K4 demethylase, SPR-5, and H3K9me is subsequently added by the histone methyltransferase, MET-2. Recently, it was demonstrated that SPR- 5 and MET-2 maternal reprogramming antagonizes the H3K36 methyltransferase, MES-4, which …

Measuring The Physiological Effects Of Methylobacterium Oryzae Foliar Inoculation Onto Salt-Stressed Tomatoes Grown In A Greenhouse Semi-Hydroponic System, Collin Dice Jun 2023

Measuring The Physiological Effects Of Methylobacterium Oryzae Foliar Inoculation Onto Salt-Stressed Tomatoes Grown In A Greenhouse Semi-Hydroponic System, Collin Dice

Master of Science in Integrative Biology Theses

Salinity stress has been shown to improve hydroponic produce quality such as that of tomato but at the trade-off of produce yield. In order to improve demand for hydroponic produce, techniques that improve salinity tolerance could offset declines in yield without altering the improved quality of produce. In two separate trials, we tested whether foliar inoculation of the ACC deaminase-producing bacteria Methylobacterium oryzae CBMB20 improved salt tolerance in tomatoes grown in a semi-hydroponic system using an indeterminate variety exposed to 26mM NaCl (Trial 1) and a determinate variety exposed to 17mM NaCl (Trial 2). We also tested how salinity and …

The City Blues Of An Iridescent Canary: Physiological, Behavioral, And Developmental Impacts Of Lead (Pb) On Songbirds Along An Urban-To-Rural Gradient, Michelle Ross Jun 2023

The City Blues Of An Iridescent Canary: Physiological, Behavioral, And Developmental Impacts Of Lead (Pb) On Songbirds Along An Urban-To-Rural Gradient, Michelle Ross

Master of Science in Integrative Biology Theses

Urbanization is rapidly changing the environment and creating new challenges in the lives of animals across the globe. Anthropogenic contaminants found commonly in old construction materials—including heavy metals like lead— persist within the environment for prolonged periods of time and present a widespread problem for all who live near contaminated areas. Despite the phase-out of lead usage, it continues to threaten the health of all organisms but especially those from urban areas where historical lead use was more common. Currently, the sub-lethal effects of lead on wildlife are not well understood, though lead is known to affect physiology and behavior …

Reintroducing Hemp (Rongony) In The Material Palette Of Madagascar: A Study On The Potential Of Hemp Clay Components And Its Impact On Social And Ecological Communities., Henintsoa Thierry Andrianambinina Jun 2023

Reintroducing Hemp (Rongony) In The Material Palette Of Madagascar: A Study On The Potential Of Hemp Clay Components And Its Impact On Social And Ecological Communities., Henintsoa Thierry Andrianambinina

Masters Theses

When mentioning the word hemp, especially in the local language of Madagascar, the literal translation does not set it apart from marijuana, as they are both called “rongony” - creating the stigma around hemp as the negative stereotype of marijuana. However, the material has been used by the ancestors of Madagascar, as well as across cultures, in its fibrous form to produce fabrication like textile goods and packaging. During colonization, the prohibition of hemp intensified, and since then, any activity related to either of these plants is prohibited and will end in severe punitive measures. This thesis explores the strengths …

Fluidity And Inconstancy: Australian Bush Tomatoes As An Exemplar Of Non-Normative Sex Expression, Christopher T. Martine Jun 2023

Fluidity And Inconstancy: Australian Bush Tomatoes As An Exemplar Of Non-Normative Sex Expression, Christopher T. Martine

Faculty Journal Articles

Solanum, a genus of ~1500 global species, is one of the more interesting plant groups in which to study reproductive biology and ecology. Overwhelmingly, species in this group express full cosexuality, where individual plants have flowers containing both fully-functioning “male” (staminate) and “female” (carpellate) organs. However, there have been multiple and widespread evolutionary transitions within the genus to non-normative variations on this ancestral condition. Australian bush tomatoes (ca. 40 species) are especially diverse in this regard, with uncommon variation and combinations of unisexuality and cosexuality -- including, most notably, two sexual systems known as dioecy (unisexual male or female …

Effects Of Intertidal Position On The Response To Oxygen And Desiccation Stress In The Common Acorn Barnacle, Balanus Glandula, Megan M. Dotterweich Jun 2023

Effects Of Intertidal Position On The Response To Oxygen And Desiccation Stress In The Common Acorn Barnacle, Balanus Glandula, Megan M. Dotterweich

Master's Theses

Sessile invertebrates in the rocky intertidal experience intermittent periods of air exposure due to tidal flux, presenting risks of temperature extremes, hypoxia, nutrient limitation, and most dangerously, desiccation. Microscale variation in severity and frequency of these risks is widely dependent on vertical position within the intertidal zone. Common acorn barnacles (Balanus glandula) have a wide vertical distribution in the intertidal, creating large differences in microhabitat between the highest and lowest individuals in the population. This study set out to explore whether tidal position dependent differences exist in the response to oxygen and desiccation stress in B. glandula. …

The Effects Of Urban Landscape, Soundscape, And Light Pollution On Avian Diversity And Nesting In South San Antonio, Texas, Alfredo Llamas May 2023

The Effects Of Urban Landscape, Soundscape, And Light Pollution On Avian Diversity And Nesting In South San Antonio, Texas, Alfredo Llamas

Masters Theses (Archived)

As critical habitat continues to dwindle due to the expansion of urbanization, alternative habitat in urban ecosystems becomes a necessary natural resource for the survival of birds. In the last decade, local San Antonio environmental authorities have focused their efforts on restoring the San Antonio Mission Reach. Ecological revitalization of the San Antonio Mission Reach could increase avian, and flora biodiversity with ongoing restoration, yet how birds use restored habitat has not been assessed. Additionally, south of the Reach, two more peri-urban sites have great potential to be high quality habitat for birds but have not been surveyed for nesting …

Proximate Causes Of Alternative Reproductive Tactics In Blue Ridge Two-Lined Salamanders (Eurycea Cf. Wilderae), Yatin Kalki May 2023

Proximate Causes Of Alternative Reproductive Tactics In Blue Ridge Two-Lined Salamanders (Eurycea Cf. Wilderae), Yatin Kalki

Master of Science in Integrative Biology Theses

Alternative reproductive tactics (ARTs) refer to discrete variation in reproductive behavior between members of a sex and within a species. ARTs are present in Blue Ridge two-lined salamanders (Eurcyea cf. wilderae) in the form of male polymorphism. Two male morphs exist: “searching” males and “guarding” males. Each phenotype has a unique reproductive ecology and associated discrete morphological differences. Another trait that shows discrete variation in E. cf. wilderae is the larval period, which may be one or two years in length. This thesis explores the proximate causes of ARTs in a population of E. cf. wilderae from the …

Investigating Stormwater Parameters From Runoff On East Tennessee State University Campus, Abby Mciver, Dr. Joseph R. Bidwell

Undergraduate Honors Theses

Climate change has caused an increase in extreme rain events and flooding in certain regions across the globe. During rain events, water flows over impervious surfaces structures such as roads and sidewalks, picking up contaminants such as metals, fertilizers and other nutrients, and various organics that which may impact organisms in such as streams, river, and lakes. Previous work has found significant differences in survival of organisms that were exposed to contaminated stormwater runoff. This study investigated stormwater chemistry parameters at collection sites on the East Tennessee State University campus. Sites were selected based on the extent of human interaction …

Impact Of Lyophilization On Porcine Hemoglobin Properties., Mustafa Almosawi May 2023

Impact Of Lyophilization On Porcine Hemoglobin Properties., Mustafa Almosawi

College of Arts & Sciences Senior Theses

Blood transfusion is the single most often performed lifesaving procedure in hospitals worldwide. Unfortunately, packed red blood cells (RBCs) used for transfusion can only be stored for 42 days at 4 °C before being discarded due to irreversible damage that occurs during storage. Any reduction in available RBCs for an extended period can lead to blood shortages. To increase the shelf-life of RBCs, we investigated freeze-drying (lyophilizing) in the presence of the non-toxic sugar trehalose as a method for long-term preservation. However, the oxidative stress of the lyophilization and storage processes can compromise the functionality of these cells, and the …

Past And Present Patterns Of Neutral And Adaptive Genetic Diversity In Wild Mandrills (Mandrillus Sphinx), Anna Weber May 2023

Past And Present Patterns Of Neutral And Adaptive Genetic Diversity In Wild Mandrills (Mandrillus Sphinx), Anna Weber

LSU New Orleans Theses and Dissertations

Although primates have fascinated researchers and the public alike for generations, one species that has remained enigmatic is the mandrill (Mandrillus sphinx), a large Cercopithecine monkey endemic to Central Africa. Mandrills are currently in decline due to bushmeat hunting, urbanization, and habitat loss. Neutral and adaptive genetic diversity are important tools for understanding evolutionary history and future viability, since diversity influences a species’ ability to adapt to a changing environment. However, thus far, minimal genetic information has been available for wild mandrills. Because of the dense vegetation in their tropical forest habitat, studying wild mandrills has proven to …

Soil Microbial Community Composition Of White Oak Mountain, Tennessee, Matthew Gano, Timothy D. Trott Apr 2023

Soil Microbial Community Composition Of White Oak Mountain, Tennessee, Matthew Gano, Timothy D. Trott

Research in Biology

Abstract - Soil microbial communities are responsible for nutrient cycling in terrestrial ecosystems and have symbiotic and parasitic relationships with the plant community. However, little is known about the factors that determine the soil microbial community composition. In this study we examined how spring wildflower diversity and geographical factors influence the soil microbial community composition of the second growth oak hickory forests of White Oak Mountain in Southeast Tennessee. The characterization of the soil microbial community was completed with 16S/18S/ITS rDNA amplicon sequencing of total DNA extracted from soil samples that were normalized for each sample plot. Here we characterize …
