  • Analysis of energy flow in US GLOBEC ecosystems using end-to-end models 

    Ruzicka, James J.; Steele, John H.; Gaichas, Sarah K.; Ballerini, Tosca; Gifford, Dian J.; Brodeur, Richard D.; Hofmann, Eileen E. (The Oceanography Society, 2013-12)
    End-to-end models were constructed to examine and compare the trophic structure and energy flow in coastal shelf ecosystems of four US Global Ocean Ecosystem Dynamics (GLOBEC) study regions: the Northern California Current, ...
  • Balancing end-to-end budgets of the Georges Bank ecosystem 

    Steele, John H.; Collie, Jeremy S.; Bisagni, James J.; Gifford, Dian J.; Fogarty, Michael J.; Link, Jason S.; Sullivan, B. K.; Sieracki, Michael E.; Beet, Andrew R.; Mountain, David G.; Durbin, Edward G.; Palka, D.; Stockhausen, W. T. (2007-05-09)
    Oceanographic regimes on the continental shelf display a great range in the time scales of physical exchange, biochemical processes and trophic transfers. The close surface-to-seabed physical coupling at intermediate scales ...
  • Comparing species and ecosystem-based estimates of fisheries yields 

    Steele, John H.; Gifford, Dian J.; Collie, Jeremy S. (2011-06)
    Three methods are described to estimate potential yields of commercial fish species: (i) single-species calculation of maximum sustainable yields, and two ecosystem-based methods derived from published results for (ii) ...
  • Construction kits or virtual worlds; management applications of E2E models 

    Steele, John H.; Aydin, Kerim; Gifford, Dian J.; Hofmann, Eileen E. (2011-10)
    We review briefly the diversity of modeling activity that comes under the rubric of end-to-end (E2E) models, but the focus of this paper – of joint concern to researchers and to managers - is on applications to management ...
  • End-to-end foodweb control of fish production on Georges Bank 

    Collie, Jeremy S.; Gifford, Dian J.; Steele, John H. (2009-05-06)
    The ecosystem approach to management requires the productivity of individual fish stocks to be considered in the context of the entire ecosystem. In this paper, we derive an annual end-to-end budget for the Georges Bank ...
  • Reconciling end-to-end and population concepts for marine ecosystems 

    Steele, John H.; Gifford, Dian J. (2010-05-06)
    The inherent complexities in the structure and dynamics of marine food webs have led to two major simplifying concepts, a species-centric approach focused on physical processes driving the population dynamics of single ...
