  • 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...

  • Tracking Bacterial and Viral Shifts in Three Organisms to Shed Light on the Complex Role of Microbes in Coral Reef Health

    Creator:
    Messyasz, Adriana
    Abstract:
    Stony corals are the ecosystem engineers of the vital, dynamic, and complex marine ecosystem known as coral reefs. Globally, coral reefs are undergoing degradation from multiple anthropogenic stressors. Coral reef organism holobionts, or the host along with its microbial components, are key to reef ecosystem success and functioning. Marine microbes...

  • What is killing the corals? Viral and bacterial interrogations using metagenomics and microscopy

    Creator:
    Soffer, Nitzan
    Abstract:
    Corals have multiple roles in maintaining ocean health and are some of the world’s most diverse ecosystems. The coral animal is host to a multitude of taxa, including symbiotic dinoflagellate algae, fungi, bacteria, protists, and viruses. Environmental stressors and disease agents can perturb the delicate balance of the coral host...

  • Bacterial Predation in Host Microbiomes

    Creator:
    Welsh, Rory M.
    Abstract:
    In host-associated microbiomes, the mechanisms that regulate community composition or the principles that govern dynamics remain far from clear. However, understanding how the structure of microbial communities shift as the system moves away from a healthy state is critical to assessing disease progression and to formulate any potential mitigation strategy....

  • Impacts of Environmental Change on a Newly-characterized Symbiosis between a Novel Bacterial Parasite, Genus Aquarickettsia, and the Coral Acropora cervicornis

    Creator:
    Klinges, J. Grace
    Abstract:
    Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...

  • The Evolution of Scleractinian Microbial Symbionts

    Creator:
    McMinds, Ryan C.
    Abstract:
    The modern world has presented many threats to the health and stability of ecosystems worldwide. One of the most biodiverse ecosystems, coral reefs, faces particularly strong pressures, and is already declining rapidly in complexity and area. Although the stressors that affect reefs are diverse, ranging from nutrient pollution to overfishing,...

  • The use of omics for disease evaluation in the brains of marine mammals

    Creator:
    Rosales, Stephanie
    Abstract:
    Marine mammals are top predators that are essential for the health and function of our oceans. These top predators are often affected by various factors that can be detrimental to their populations. Therefore, there is a need to evaluate undetermined causes of deaths and to better understand known diseases in...

  • 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...

  • Influence of the Environment and Morphology on Physiological and Genomic Homeostasis in a Temperate Cnidarian-microbe Symbiosis

    Creator:
    Koch, Jack C.
    Abstract:
    Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...

  • Comparative Genomics of Freshwater Bloom-Forming Cyanobacteria and Associated Organisms

    Creator:
    Driscoll, Connor B.
    Abstract:
    The advent of improved DNA sequencing technologies has allowed the analysis of various microbial communities. Bloom-forming freshwater cyanobacteria can produce toxins and taste-and-odor compounds that can negatively affect drinking water supplies. Here, I have employed second- and third-generation sequencing technologies to characterize bloom-forming freshwater cyanobacterial genomes and their associated heterotrophic...
