  • The Role of Circadian Transcription Factors in Gonadotropin-Releasing Hormone Gene Expression

    Creator:
    Gombart, Zoë J.
    Abstract:
    Circadian regulation is essential for many physiological functions, from sleep/wake patterns to hormonal rhythms. While the brain’s biological clock, the suprachiasmatic nucleus (SCN), likely plays a role in reproductive rhythms, it remains unknown if intracellular circadian clocks elsewhere contribute to the neuroendocrine control of reproduction. Gonadotropin-releasing hormone (GnRH) stimulates pituitary...

  • Mahler's order functions and algebraic approximation of p-adic numbers

    Creator:
    Dietel, Brian Christopher
    Abstract:
    If P is an integer polynomial denote the degree of P by ∂(P) and let H(P) be the maximum of the absolute value of the coefficients of P. Define Λ(P)=2[superscript ∂(P)]H(P) and for a fixed prime p let C[subscript p] denote the completion of the algebraic closure of the p-adic...

  • Development of sex-specific differences in Drosophila melanogaster neurons

    Creator:
    Duong, Huong T.
    Abstract:
    Many diseases cause a heavier burden on women than on men; however, treatment guidelines are based largely on data on men (NCBI, 2012). It becomes obvious that certain differences in genetics between men and women account for specific sex-related diseases, but there is too spare research focus on that issue....

  • Regulation by male-specific fruitless of neural circuitry used during courtship and copulation behavior in Drosophila melanogaster

    Creator:
    Latham, Kristin Lynn
    Abstract:
    Courtship and copulation behaviors in Drosophila melanogaster males are regulated by sex-specific products from the gene fruitless (fru). Male-specific FRU proteins (FRU[superscript M]) are putative transcription factors of the BTB-ZnF family that likely act by controlling development and maintenance of the neural circuitry used during male sexual behavior. However, which...

  • The Interaction Between the fruitless Gene and Complex Behavior in Drosophila

    Creator:
    Humphrey, Whitney M.
    Abstract:
    CantonS wild-type flies were used to determine sex-specific differences in the daily locomotor activity patterns in males and females. Under light entrainment, when flies are kept in a 12:12 light-dark condition, both males and females showed bimodal activity with a morning peak around lights-on and an evening peak around lights...

  • Habitat Use of Female Columbian Black-tailed Deer in Western Oregon

    Creator:
    Schrautemeier, Timothy J.
    Abstract:
    Columbian black-tailed deer (Odocoileus hemionus columbianus) are important economically, ecologically, and culturally as an indigenous species in western Oregon. Oregon Department of Fish and Wildlife (ODFW) observed declines in black-tailed deer populations since the late 1980’s and attributes these declines to reduction in quality and availability of habitat, following the...

  • Partial Characterization of the Danio rerio and Xenopus tropicalis MT-­‐Ox Enzyme Involved in Gadusol Biosynthesis

    Creator:
    Roemelt, Taylor
    Abstract:
    Ultraviolet (UV)-protective compounds, such as mycosporine-like amino acids (MAA) are critical for the survival of marine organisms exposed to high-solar radiation. A chemically similar compound, gadusol, was discovered in eggs of the atlantic cod in 1980, and was originally thought to be derived from MAAs that had been ingested. However,...

  • Beaver ecology in Bridge Creek, a tributary to the John Day River

    Creator:
    Maenhout, Julie L. (Harper)
    Abstract:
    The American beaver (Castor canadensis) was nearly extirpated by the late 1800's due to the fur trade. Due to reintroduction efforts, it now occupies much of its former range. Beavers are a keystone species and ecosystem engineers, greatly influencing riparian and instream habitats through selective harvesting of plant materials and...

  • Comparative epidemiology of Phytophthora diseases of Rhododendron

    Creator:
    Taylor, Clare Rebecca
    Abstract:
    Rhododendron species are host to many Phytophthora species and are an important crop in the nursery industry. The foliar epidemiology of twelve Phytophthora diseases on Rhododendron was studied in field and growth chamber experiments on two Rhododendron cultivars. The relative aggressiveness of Phytophthora spp. was assessed using disease incidence, severity,...

  • Fourier Analysis and Equidistribution on the p-adic Integers

    Creator:
    Somasunderam, Naveen
    Abstract:
    In this dissertation, we use Fourier-analytic methods to study questions of equidistribution on the compact abelian group Zp of p-adic integers. In particu- lar, we prove a LeVeque-type Fourier analytic upper bound on the discrepancy of sequences. We establish p-adic analogues of the classical Dirichlet and Fejér kernels on R/Z,...
