  • 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, ...
  • Steele, John H. (2005-11-03)
    Ecosystem based management of marine resources is a worthy ideal. At present, however, the science is unable to measure and relate the fundamental concepts of diversity, productivity and resilience required for management ...
  • 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 ...
  • 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) ...
  • Steele, John H.; Ruzicka, James J. (2011-03)
    The wide availability of ECOPATH data sets provides a valuable resource for the comparative analysis of marine ecosystems. We show how to derive a bottom-up transform from the top-down ECOPATH; couple this to a simple NPZD ...
  • 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 ...
  • Ruzicka, James J.; Steele, John H.; Ballerini, Tosca; Gaichas, Sarah K.; Ainley, David G. (2013-04-29)
    Similarly structured food web models of four coastal ecosystems (Northern California Current, Central Gulf of Alaska, Georges Bank, southwestern Antarctic Peninsula) were used to investigate competition among whales, ...
  • 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 ...
  • 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 ...
  • Heath, Michael R.; Speirs, Douglas C.; Steele, John H. (John Wiley & Sons, 2013-12-16)
    Climate fluctuations and human exploitation are causing global changes in nutrient enrichment of terrestrial and aquatic ecosystems and declining abundances of apex predators. The resulting trophic cascades have had profound ...
  • Murawski, Steven A.; Steele, John H.; Taylor, Phillip; Fogarty, Michael J.; Sissenwine, Michael P.; Ford, Michael; Suchman, Cynthia (Oxford University Press, 2009-08-30)
    Effective marine ecosystem-based management (EBM) requires understanding the key processes and relationships controlling the aspects of biodiversity, productivity, and resilience to perturbations. Unfortunately, the scales, ...
