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...

How Do Parasites Infect Salmon? Comparative Transcriptomics Reveal Myxozoan Adaptations for Parasitism

Creator:: Americus, Benjamin
Abstract:: The phylum Cnidaria contains three main branches: Anthozoa (corals, sea anemones) Medusozoa (jellyfish, hydra), and Endocnidozoa. This latter branch is characterized by parasitism and contains the microscopic fish-parasites Myxozoa. Myxozoa are highly simplified, consisting of only a few cell types, however they have retained the nematocyst stinging cells and complex...

Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

Chlamydiae under stress : environmental conditions influence the production and localization of chlamydial antigens

Creator:: Brown, Wendy J.
Abstract:: Chlamydiae are obligate intracellular pathogens that cause several serious conditions within the human host. Many of the symptoms associated with infection are thought to stem from the development of aberrant, or persistent, chlamydiae. Factors leading to chlamydial persistence include deprivation of amino acids, the release of certain cellular factors, or...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

Social Evolution and Regulatory Architecture of Pseudomonas aeruginosa Quorum Sensing

Creator:: Asfahl, Kyle L.
Abstract:: Cell-cell communication in bacteria is understood to facilitate the coordination of population-wide cooperative behavior in the form of concerted gene expression. The opportunistic pathogen Pseudomonas aeruginosa uses such a communication mechanism to regulate a large group of genes important to virulence strategies in this bacterium. This general mechanism of communication...

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...

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...

The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...
