  • Interactions of wind-driven and tidally-driven circulation in the Oregon coastal ocean

    Creator:
    Osborne, John J.
    Abstract:
    Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...

  • Effects of Predator Introductions on Population and Community Dynamics

    Creator:
    Ingeman, Kurt E.
    Abstract:
    There is increasing awareness that human activities are altering the ways that natural systems operate and that local shifts in species composition and abundance can lead to abrupt and irreversible global change. Therefore, understanding the processes that buffer biological communities from critical shifts and how our actions affect natural stabilizing...

  • Indirect effects of fishing on predators and their prey

    Creator:
    Stallings, Christopher Derek
    Abstract:
    Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...

  • Invasive Pacific Lionfish Alters Native Community Interactions on Atlantic Coral Reefs

    Creator:
    Kindinger, Tye L.
    Abstract:
    Biological invasions have been identified as one of the prominent drivers of global environmental change. In particular, invasive predators typically have substantial negative effects on populations of native prey, even driving species to extinction in extreme cases. However, beyond direct predatory effects, little is understood regarding the specific mechanisms by...
