  • Pheromone Variation in Plethodontid Salamanders

    Creator:
    Chouinard, Adam J.
    Abstract:
    Plethodontid salamanders have served as an informative vertebrate system for studying the role of chemical signals in facilitating social and reproductive behaviors. Individuals produce complex mixtures of chemicals from multiple glandular regions. In total, these secretions convey a wide variety of information, and are important for numerous inter- and intraspecific...

  • The role of innate immunity in cnidarian-dinoflagellate symbiosis

    Creator:
    Poole, Angela Z.
    Abstract:
    Cnidarians, such as corals and sea anemones serve as hosts to a variety of organisms including symbiotic dinoflagellates, bacteria, virus, and apicomplexans. As corals are vital to the health and productivity of the reef ecosystem it is important to understand how these organisms interact with each component of the holobiont....

  • Temperature stress, gene expression, and innate immunity at the onset of cnidarian-dinoflagellate symbiosis

    Creator:
    Schnitzler, Christine E.
    Abstract:
    The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...

  • Mutual mate choice in a terrestrial salamander, Plethodon shermani, with long-term sperm storage

    Creator:
    Eddy, Sarah L.
    Abstract:
    Sexual selection can influence the mating system of an organism through multiple mechanisms. These mechanisms result in variation in reproductive success among individuals, and include scramble competition, endurance rivalries, contests, mate choice and cryptic choice, and sperm competition. Understanding the mating system of a species requires the identification of which...

  • Pheromone mechanisms and behavioral strategies for maximizing courtship success in a terrestrial salamander, Plethodon shermani

    Creator:
    Vaccaro, Elyse A.
    Abstract:
    Darwin devised the evolutionary theory of sexual selection to account for the manifold extravagances of courtship behaviors and displays. Mating interactions represent a major evolutionary process driving the elaboration, vibrancy, and peculiarity of these courtship traits. For my dissertation research, I strived to elucidate the dynamics that constitute the complex...

  • Adaptive diversity and divergence at frog antimicrobial peptide loci

    Creator:
    Tennessen, Jacob A.
    Abstract:
    In this dissertation I study evolutionary patterns at genes encoding antimicrobial peptides (AMPs) in frogs. AMPs are short, amphipathic, cationic, secreted proteins that kill bacteria and other pathogens through a non-catalytic mechanism that involves binding to and disrupting the microbial cell membrane. In many animal taxa, positive selection is much...
