  • White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

    Creator:
    Viste-Sparkman, Karen
    Abstract:
    Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...

  • 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...
