  • 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, ...
  • Constructing end-to-end models using ECOPATH data 

    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 ...
  • Dividing up the pie : whales, fish, and humans as competitors 

    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, ...
