  • Water Efficiency for Urban Landscapes in Semi-Arid Environments

    Creator:
    Martinson, Richard W.
    Abstract:
    Urban landscape water use is increasingly a focus of water conservation efforts. This is especially true in the arid and semi-arid regions of the western United States where increased demand, environmental concerns, and extended periods of drought have created chronic water shortages. However, until recently, little attention has been paid...

  • Construction, Degradation, and Restoration of Wet Meadow Ecosystems in Semi-arid Landscapes, Northern Great Basin, USA

    Creator:
    Nash, Caroline S.
    Abstract:
    Wet meadow ecosystems are a useful natural laboratory in which to explore feedbacks between biogenic and geologic controls on valley bottom landforms. Characterized by flat valley floors flanked by higher-gradient hillslopes, these meadows are singular both in that they represent depositional features in what is primarily an erosional environment, and...

  • Directing ecological succession : the role of competition in restoring semi-arid grasslands dominated by invasive plants

    Creator:
    Mangla, Seema
    Abstract:
    Successful ecosystem restoration requires an understanding of the ecological processes directing succession. One of the challenges in the semi-arid grasslands of western United States is replacement of native species by invasive annual grasses. Solutions to this problem require identifying and manipulating ecological processes that direct succession to favor desired vegetation....

  • Drought, dispersal, and community dynamics in arid-land streams

    Creator:
    Bogan, Michael T.
    Abstract:
    Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; these processes act as filters that reduce the regional species pool down to the observed local community. In...

  • Ecohydrological mediation of water budget partitioning and time scales of subsurface flow in a seasonally semi-arid grassland

    Creator:
    Pangle, Luke A.
    Abstract:
    Understanding how the interactions and feedbacks between plant function, climate, and soils ultimately affects the terrestrial water balance and subsurface flow processes is major challenge in scientific hydrology. This dissertation summarizes the findings of a manipulative climate warming experiment, an observational field study that utilized stable-isotope tracers, and associated modeling...

  • Opening Pandora's Box at the Roof of the World : The Past and Present of Avian Influenza Science

    Creator:
    Canavan, Barbara C.
    Abstract:
    By means of a case study and historical analysis, this dissertation examines the past and present of avian influenza. By integrating disconnected histories of human and animal influenza, this dissertation links historical insights with the concerns of contemporary avian flu science. It is not only a natural history of avian...

  • Honey Bees and Apple Trees : Hood River, Oregon as a Case Study for the Creation of the Honey Bee Pollination Industry

    Creator:
    Kellar, Brenda M.
    Abstract:
    The use of honey bees to pollinate apple orchards seems natural, even inevitable. This dissertation examines the relationship of beekeeping and apple growing in Hood River, Oregon in the mid-nineteenth to the mid-twentieth centuries, as a case study in the development of commercial pollination service. Within this time period the...

  • Mars and Popular Astronomy, 1890-1910

    Creator:
    Simpson, Emily M.
    Abstract:
    Beginning in the late-nineteenth century, several dialogues emerged concerning life on Mars. Some supported the notion of an inhabited Mars, citing recent observations of the planet, while others, pointing to a lack of concrete evidence, denied the validity of such a bold hypothesis. The dialogues within and between different...

  • Rocks and reactors : an atomic interpretation of human rights, 1941-1979

    Creator:
    Richards, Linda Marie
    Abstract:
    The atomic age was enacted by many scientists as a way to realize health and human rights. Human rights were conceived in this context as rights to economic development, science education, and nuclear medicine. The United States Atomic Energy Commission (AEC) acted hand in hand with UN agencies and educators...
