  1. Lessons learnt from a comparison of three ecosystem models for Port Phillip Bay, Australia

    Lessons learnt from a comparison of three ecosystem models for Port Phillip Bay, Australia

    Item type: Journal Article • Journal: African Journal of Marine Science • Authors: E. A. Fulton A. D. M. Smith
    Comparing multiple models applied to the same system can be highly instructive, both with regard to the system of interest and the models. In this case, three ecosystem simulation models (ECOSIM, Bay Model 2 [BM2] and the Integrated Generic Bay...

  2. A critical look at the potential of Ecopath with ecosim to assist in practical fisheries management

    A critical look at the potential of Ecopath with ecosim to assist in practical fisheries management

    Item type: Journal Article • Journal: African Journal of Marine Science • Authors: É. E. Plagányi D. S. Butterworth
    Ecosystem-orientated thinking is increasingly incorporated into fishery management. Given the complexity of ecosystem processes, there is a need to evaluate the tools used to steer this thinking critically. ECOPATH with ECOSIM (EwE), an aggregate system-modelling package, is currently the most...

  3. Age structure or functional response? Reconciling the energetics of surplus production between single-species models and ECOSIM

    Age structure or functional response? Reconciling the energetics of surplus production between single-species models and ECOSIM

    Item type: Journal Article • Journal: African Journal of Marine Science • Authors: K. Y. Aydin
    Whole-ecosystem foodweb models, specifically the dynamic model ECOSIM, contain specific hypotheses for surplus production that differ from traditional single-species management models. Specifically, ECOSIM begins with an assumption that all species are tightly connected and energetic surplus does not arise through...

  4. Supporting marine spatial planning with an ecosystem model of Algoa Bay, South Africa

    Supporting marine spatial planning with an ecosystem model of Algoa Bay, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science • Authors: K Ortega-Cisneros --- , South Africa E Weigum --- , South Africa R Chalmers --- , South Africa S Grusd --- , South Africa AT Lombard --- , South Africa L Shannon --- , South Africa
    The Ecopath with Ecosim (EwE) modelling framework was used to develop a model of Algoa Bay and test the ecosystem impacts of the implementation of the Addo Elephant National Park Marine Protected Area (MPA). The Ecopath model included 37 functional...
