  • Multiscale assessment of thermal patterns and the distribution of chinook salmon in the John Day River Basin, Oregon

    Creator:
    Torgersen, Christian E.
    Abstract:
    This study examined the distribution and behavior of adult spring chinook salmon (Oncorhynchus tshawytscha) related to patterns of stream temperature and physical habitat at channel unit, reach, and basin-wide spatial scales in both a wilderness stream and a disturbed stream in the John Day River basin in northeastern Oregon. Thermal...

  • Addressing Data Resolution in Precision Agriculture

    Creator:
    Kelley, Jason
    Abstract:
    Irrigated agriculture constitutes the greatest consumptive water use globally, so that irrigation efficiency measures are an important part of global efforts to best utilize this limited resource. However, greater irrigation efficiency must be achieved while simultaneously maintaining or increasing crop yields and farming profitability. Incremental water use decisions are made...

  • Tempo and Mode of Diversification in the Neotropical Fish Superfamily Anostomoidea (Ostariophysi: Characiformes)

    Creator:
    Frable, Benjamin W.
    Abstract:
    Neotropical characiform fishes form one of the most diverse freshwater ichthyofauna in the world. Knowledge of evolutionary processes that generated and maintain the immense characiform lineage and morphological diversity is still poorly understood. When did characiform lineages diversify? How have major geological and environmental changes affected diversification? Why are some...
