  • Cellular Recognition, Division, and Proliferation in the Cnidarian-Dinoflagellate Symbiosis

    Creator:
    Tivey, Trevor R.
    Abstract:
    Cnidarians and their symbiotic dinoflagellates form a productive mutualism that shapes marine environments. In this symbiosis, dinoflagellate species from the family Symbiodiniacea reside within cnidarian host gastrodermal cells and provide the host with photosynthetically fixed carbon in exchange for host metabolites. This nutritional exchange allows both partners to thrive in...

  • 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...

  • Metabolic and Immune Responses in Cnidarian-Symbiodiniaceae Symbiosis and Dysbiosis

    Creator:
    Sawiccy, Valeri
    Abstract:
    Coral reefs, found in tropical regions, are renowned for their rich biodiversity and their contributions to ecological, cultural, and economic aspects worldwide. The success of coral reefs hinges on the symbiotic partnership between corals and their dinoflagellate algae, from the family Symbiodiniaceae. The algae reside within the coral host’s gastrodermal...

  • Infectious diseases of the Felidae : parasite communities from miniature to massive

    Creator:
    Broughton, Heather M.
    Abstract:
    Direct anthropogenic stressors have caused drastic declines in wildlife populations over the past two centuries. In the face of these threats, spillover of infectious disease from domestic animals and livestock into wildlife, and novel interactions between parasites and pathogens within wildlife communities, have further suppressed already vulnerable populations. As management...

  • The Influence of Prey Predictability on the Foraging Behavior and Movement of Intertidal Predators

    Creator:
    Hennessey, Shannon M.
    Abstract:
    Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or maintain population-, community-, or ecosystem-level patterns. Individual diet variation, defined as individual variation in food resource use within a population that is consistent over time, is...

  • Phylogenomics and Evolution of Ground Beetles, with an Emphasis on the Speciose Tribes Chlaeniini and Bembidiini (Coleoptera: Carabidae)

    Creator:
    Pflug, James M.
    Abstract:
    In this dissertation, I investigate the evolution and genomes of carabid beetles, a worldwide family of over 38,000 species. I focus on two species-rich groups, the tribes Chlaeniini and Bembidiini, both of which are primarily found on the shores of bodies of water. The former are distinctive for their defensive...

  • Evolutionary Dynamics of Genomes and Endosymbionts in Plant-Parasitic Nematodes

    Creator:
    Wasala, Wasala Mudiyanselage Sulochana K.
    Abstract:
    Plant-parasitic nematodes cause more than US $100 billion in annual agriculture loss worldwide. Thorough knowledge of their genetic diversity, and interactions with endosymbionts and environment have the potential to provide valuable insights into the basic biology of these animals, and assist future efforts aimed at management of these plant parasites....

  • Turn-Taking in Face-to-Face Conversations: A Proposed Theory of Chair Swiveling

    Creator:
    Smith, Lyshuand R.
    Abstract:
    The purpose of this thesis is to propose swiveling behavior as a potential speech transitioning device and to discuss the methodology behind qualitative and quantitative analysis of swivels in relation to subjects’ partners. Due to the impacts of gaze and body orientation direction on speech transitioning, it is deduced that,...

    Abstract:
    In this dissertation, I present the results from three studies: (1) a phylogeny of Tenebrionoidea (Coleoptera) inferred from a seven-gene dataset derived from PCR and Sanger sequencing; (2) a phylogeny of Tenebrionidae, the largest family in Tenebrionoidea, inferred from a four-gene dataset also derived from PCR and Sanger sequencing; (3)...

  • Life History of the Northern Rubber Boa (Charina bottae) in Oregon

    Creator:
    Leppin, Mark V.
    Abstract:
    The Northern Rubber Boa (Charina bottae) is a small, secretive boa native to the Pacific Northwest. Despite this being possibly the highest latitude boas and one of only two boas native to the continental U.S., it has received surprisingly little attention. Most of the research on the natural history of...
