  • Photo-enhanced Toxicity of Oil Constituents and Corexit 9500 to Gulf of Mexico Marine Organisms

    Creator:
    Finch, Bryson E.
    Abstract:
    Significant inputs of hydrocarbons are continually released into the environment from anthropogenic and natural sources. Some of the most toxic hydrocarbon compounds are polycyclic aromatic hydrocarbons. Polycyclic aromatic hydrocarbons are known for their ability to absorb ultraviolet light and enhance toxicity. Generally, PAHs exert their toxicity via narcosis but UV-absorbing...

  • Moving Towards Academic Success and Life Long Learning

    Creator:
    Becker, Derek R.
    Abstract:
    Early learning skills, such as executive function (EF), are a key component of healthy development and predict long-term academic success. Yet many children are entering kindergarten without the necessary skills (including EF) that are needed to set them on a successful learning trajectory. Early prekindergarten classrooms that encourage a high...

  • The antibiotic discovery era (1940-1960) : vancomycin as an example of the era

    Creator:
    McGraw, Donald J.
    Abstract:
    An examination of the technical and historical literature concerning the discovery and development of antibiotics suggests the possible existence of an era of discovery. This era appears to have a well-defined beginning (about 1940) and a well-defined close (about 1960). It is the purpose of this dissertation to examine the...

  • A closed root environment for plant production

    Creator:
    Blackburn, Bryan (Bryan Keith), 1955-
    Abstract:
    Thesis research focused on: 1) Water and fertilizer gradients within the plant root zone, and effects of chemical and physical gradients on Trichoderma harzianum populations. 2) Regulation of root growth physically with permeable fabric containers and chemically with copper compounds. 3) Effects of copper coatings for fabric containers on Glomus...

  • Gene regulatory networks during muscle development

    Creator:
    Eng, Diana G.
    Abstract:
    Congenital myopathies are caused by heritable mutations in particular genes. Genes mutated in congenital muscular dystrophies often encode cytoskeletal proteins, which contribute to the shape and movement of cells. We would like to know how such molecular defects lead to the muscle weakness in patients. It is therefore important to...

  • 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,...

  • Taxonomy and evolution of the Orthotyline genus Lopidea (Heteroptera: miridae)

    Creator:
    Asquith, Adam
    Abstract:
    The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...

  • Visualization in environmental science

    Creator:
    Winters, Kirsten M.
    Abstract:
    The VISualization of Terrestrial and Aquatic Systems (VISTAS) software development project began with the proposition that visualization would increase the ability of scientists to explore and communicate their data, especially complex datasets that span multiple spatial and temporal scales. A case study of VISTAS articulates how and why scientists intend...

  • Rift Valley fever in African buffalo (Syncerus caffer) : basic epidemiology and the role of bovine tuberculosis coinfection

    Creator:
    Beechler, Brianna
    Abstract:
    Rift Valley fever (RVF) is a mosquito-borne zoonotic viral disease native to the African continent. Outbreaks tend to occur in the wet seasons, and can affect numerous mammalian species including African buffalo. It is debated how the virus survives the inter-epidemic period when it is not detected in mammalian populations,...
