  • Evaluation of data-poor and age-structure management strategies for west coast rockfish

    Creator:
    Arnold, Linsey M.
    Abstract:
    Management strategies to prevent overfishing while achieving optimum yield vary according to the available data and life history of the fished stock. I evaluated two sets of management strategies for Pacific coast rockfish: strategies to set harvest limits for data-poor stocks, and strategies intended to protect the age structure of...

  • Predicting the stability, equilibrium response, and nonequilibrium dynamics of ecological systems

    Creator:
    Hosack, Geoffrey R.
    Abstract:
    In this dissertation, new theory and its applications are developed to predict three properties of complex ecological communities: stability, equilibrium response, and non-equilibrium dynamics. First, a graph-theoretic analysis identifies the interconnections in a complex ecosystem that promote or diminish stability (Chapter 2). The hierarchy of interactions that influences stability and...

  • Quantitative Tools for Monitoring Strategy Evaluation and Assessment of Sea Turtle Populations

    Creator:
    Piacenza, Susan E. H.
    Abstract:
    Green sea turtles, Chelonia mydas, have endangered and threatened populations globally, but several populations show signs of population recovery. In Hawaii, nesting female green turtles have increased 5.7% year⁻¹ since 1973, but wide fluctuations in census counts of nesting females make recovery diagnosis difficult. For effective management planning, it is...

  • The Factors Affecting the Diets of Groundfish in the Gulf of Alaska : Ecological and Modeling Considerations

    Creator:
    Thompson, Kevin A.
    Abstract:
    Marine systems undergo changes in community composition over time as a result of a variety of environmental and anthropogenic factors. Understanding these community changes and the factors that drive them is critical for ecosystem management of marine resources. The Gulf of Alaska (GOA) is a large marine ecosystem that includes...

  • Evaluating the data-poor fishery stock assessment method, DB-SRA

    Creator:
    Owashi, Brandon R.
    Abstract:
    Depletion-Based Stock Reduction Analysis (DB-SRA; Dick and MacCall, 2011) is a catch-only fisheries stock assessment model that has been developed to estimate an overfishing limit (OFL) in data-poor situations. DB-SRA projects the biomass trajectories of a stock by means of a catch time series and five parameters: the instantaneous, per...
