  • The genetics of winterhardiness in barley : perspectives from genome-wide association mapping

    Creator:
    von Zitzewitz, Jarislav
    Abstract:
    Fall-planted barley makes the best use of available precipitation in the Pacific Northwest of the United States. This growth habit is also suitable to many other areas of the world. A prerequisite for production in most of these areas is tolerance of low temperature during the vegetative growth stages. Fall-planted...

  • Classifying seven dimensional manifolds of fixed cohomology type

    Creator:
    Montagantirud, Pongdate
    Abstract:
    Finding new examples of compact simply connected spaces admitting a Riemannian metric of positive sectional curvature is a fundamental problem in differential geometry. Likewise, studying topological properties of families of manifolds is very interesting to topologists. The Eschenburg spaces combine both of those interests: they are positively curved Riemannian manifolds...

  • Carnivore Competition: Spatial and Dietary Implications of Gray Wolf Recolonization for Cougars in Northeast Oregon

    Creator:
    Orning, Elizabeth Kari
    Abstract:
    After a 40-year absence from Oregon’s landscape, expanding gray wolf (Canis lupus) populations are reestablishing elements of interspecific competition with sympatric large carnivores, like cougars (Puma concolor). This presents new challenges for management of large carnivores and their ungulate prey populations (e.g., elk, Cervus canadensis nelsoni; mule deer, Odocoileus hemionus)...

  • Environmental Variables and Gene Expression Profiles Associated with Cueing Reproductive Events in Cnidarians

    Creator:
    Crowder, Camerron M.
    Abstract:
    Coral reproduction is vital to the persistence of coral reefs. Decades of ecological studies have correlated environmental variables, such as temperature and light, to the timing of reproduction in anthozoan cnidarians, including corals and sea anemones. However, elevated temperatures associated with climate change impair reproductive success and threaten the resilience...

  • Gene Networks of the Skeletal Muscle Cell

    Creator:
    Singh, Arun J.
    Abstract:
    Skeletal muscle is the largest organ in the body by mass, comprising roughly 40% of total bodyweight in adults. It plays diverse and unique roles that include movement, locomotion, and support for posture and internal organs, among others. The structural foundation for all skeletal muscle in adults is formed early...

  • 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...

  • Advances in Freshwater Cyanobacterial Genomics

    Creator:
    Brown, Nathaniel M.
    Abstract:
    Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

  • Understanding Public Perceptions of Post-Wildfire Landscape Recovery

    Creator:
    Kooistra, Chad M.
    Abstract:
    Forest disturbances, such as wildfires, pine beetle outbreaks, and floods are important features of many landscapes and ecosystems. Many disturbances are increasing in size, frequency, and intensity due to changing climates and land management decisions. The changing ecological and aesthetic conditions following a disturbance can lead to negative short- and...

  • Integration of Evolutionary Theory and Genomics to Understand Processes Involved in Host Adaptation and Divergence in Phytophthora Plant Pathogens

    Creator:
    Tabima, Javier F.
    Abstract:
    Modern plant pathology benefits from integrating methods and concepts from evolutionary biology. For example, evolutionary concepts are used to identify and examine species boundaries of plant pathogens, recognize processes underlying pathogen biogeography, identify traits that characterize emerging species, and discover new molecular interactions that originate under processes of selection. In...
