Ecophylogenetic Characterization of the Gut Microbiome of At-risk Companion and Food Animals

Creator:: Kirchoff, Nicole S.
Abstract:: Agricultural and companion animals are integral to our way of life as they provide us with nourishment, financial resources, transportation, and companionship. However, pets, managed animals in the agricultural industry, as well as wild populations of food animals are all subject to health and mortality risks. The gut microbiome is...

Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

Creator:: Wang, Lu
Abstract:: Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

Multiple Stressors Drive Changes in Coral Microbiome Diversity and Composition Demonstrating the Role of a Bacterial Symbiont in Microbial Community Sensitivity and Resilience

Creator:: Maher, Rebecca L.
Abstract:: On coral reefs, disturbances rarely occur in isolation. Global stressors such as increasing seawater temperature often coincide with local stressors like nutrient pollution. In the face of increasing anthropogenic stress, corals can function as environmental sentinels, although little is known about how multiple stressors interact to disrupt their associated bacterial...

Expanding Diagnostic Assays for Pseudoloma neurophilia & Description of the Progression of Infection in Adult Zebrafish Populations

Creator:: Schuster, Corbin J.
Abstract:: Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...

Quantifying Carbon Production in Marine Ecosystems Using Expressions of Phytoplankton Physiology

Creator:: Penta, William Bryce
Abstract:: Phytoplankton initiate the marine carbon cycle by fixing carbon dioxide into biologically available compounds. These abundant single celled organisms mediate carbon flux from the atmosphere to the deep ocean and are the base of the marine food web, supplying new carbon to higher trophic levels. Phytoplankton are highly diverse and...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

Perceptions of climate change in herbalism and harvesting

Creator:: Noall, Amelia
Abstract:: This study looked at the impacts of climate change on medicinal plants, and how these impacts are viewed and understood in the herbalism community. Two literature reviews were conducted, to look at each of these two ideas: the first was a review of peer-reviewed literature describing research on climate change...

Consequences of Influenza A Virus on Pneumococcal Biofilm Formation and Stability in the Absence of Host Factors

Creator:: Nutter, Laura
Abstract:: Streptococcus pneumoniae and Influenza A Virus both primarily infect the upper respiratory tract, with more severe disease occurring during coinfection than would be caused by either pathogen independently. Until recently, characterization of the interactions between these two pathogens has occurred exclusively in the context of a host or using host-derived...

Development of a Bioluminescent Sensor of Isothiocyanates through Genetic Modification of Pseudomonas fluorescens and Validation on Crude Plant Materials

Creator:: Hogaboam, Octavia L.
Abstract:: Isothiocyanates (ITCs) are produced by roots in a variety of agricultural plants, such as those within the Brassicaceae family. ITCs act as fumigants, and are used to control microbial plant pathogens by adding brassica-origin seed meal to soil prior to replanting. However, there is suggestion that the presence of residual...

The Social Interactions of Pseudomonas aeruginosa

Creator:: Smith, Parker
Abstract:: Pseudomonas aeruginosa is a ubiquitous environmental microbe, opportunistic pathogen, and a highly social organism. P. aeruginosa utilizes a wide array of cooperative behaviors to adapt to the environmental conditions around it. These behaviors include quorum sensing (QS), a form a cell-to-cell signaling that coordinates the expression of secreted products in...
