  • Long Term Trends and Sources of Sound in United States Waters

    Creator:
    Haver, Samara M.
    Abstract:
    Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

  • The Soundcheck of the Sea : Comparing Marine Soundscapes on a Continental Scale

    Creator:
    Haver, Samara M.
    Abstract:
    Monitoring marine ambient sound using standardized methods supports assessments of ocean sound levels across widespread ecosystems. This thesis quantifies differences among coastal and deep-water marine soundscapes in the Atlantic and Pacific oceans. The sources of sound in a soundscape are compartmentalized into three components and compared over time and among...

  • "Its Own Sense of Verisimilitude" : The Lizzie Bennet Diaries As a Transhistorical Adaptation of the Semipublic

    Creator:
    Surface, Samara
    Abstract:
    The Lizzie Bennet Diaries is a multimodal adaptation of Pride and Prejudice, released from 2012-2013. As a media event, the show proved how effective transmedia storytelling can be, eventually winning an Emmy for Original Interactive Program. In creating an intensely immediate narrative world, the series adapted more than Jane Austen’s...

  • How Nearshore Currents affect Larval Dispersal and Genetic Connectivity of China Rockfish (Sebastes nebulosus) Along Oregon and Washington Coasts

    Creator:
    Avila, Alexandra M.
    Abstract:
    Connectivity of fish populations is a crucial question for fisheries conservation and the development of spatial management plans. Both adult and larval movement define the extent and direction of ecological and evolutionary overlap between geographic regions and, therefore, how we define stocks for management purposes. Within that context, my work...

  • Humpback Whale (Megaptera novaeangliae) Calling Behavior In Southeast Alaska : A Study In Acoustic Ecology And Noise

    Creator:
    Fournet, Michelle E. H.
    Abstract:
    Humpback whales (Megaptera novaeangliae) are a widely distributed baleen whale species, well known for their diverse acoustic behavior. On high-latitude foraging grounds, humpback whales produce a suite of non-song vocalizations (“calls”) in concert with foraging and social behavior. In this dissertation I investigated the role of calls in the acoustic...

  • A spatially explicit model for allocating conservation efforts : the Grand Ronde River basin, Oregon

    Creator:
    Watanabe, Michio
    Abstract:
    The spatial and dynamic pattern of landscape changes has a profound effect on the supply of environmental services, including the provision of habitat for fish and wildlife. Spatial heterogeneity is a common feature of landscapes in the Pacific Northwest, most notably in areas important to the production of salmonid fish...

  • Impact of Process Optimization and Composition on Thin Film BNKT Microstructure, Ferroelectric and Piezoelectric Response

    Creator:
    Grove, Kyle M.
    Abstract:
    Recent changes in legislation restricting lead content in waste streams produced during electronics manufacturing have inspired a strong push to develop alternative lead-free materials systems for piezoelectric applications. One lead-free piezoelectric material system, (100-X)Bi₀.₅Na₀.₅TiO₃-XBi₀.₅K₀.₅TiO₃ (BNKT), has shown promising properties in bulk research, however, difficulties have arisen in the development of...

  • Defect Mechanisms in Bismuth-based Perovskites

    Creator:
    Kumar, Nitish
    Abstract:
    The aim of this research is to develop a fundamental understanding of the dominant defect species and the relevant defect equilibrium conditions for bismuth-containing perovskites to help guide the development of these materials for emerging applications. This is of paramount importance for many demanding applications, because ultimately the defect equilibria...

  • Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

    Creator:
    Barlow, Dawn R.
    Abstract:
    The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

  • The Effects of Road Noise on Pacific Chorus Frog Communication

    Creator:
    Nelson, Danielle V.
    Abstract:
    Amphibians are experiencing global population declines and are one of the most threatened groups of vertebrates. This can be attributed to multiple environmental stressors such as habitat loss, disease, invasive species, and climate change. For vocal amphibian species, loss of acoustic habitat due to anthropogenic noise may be yet another...
