      As part of the international MENU collaboration, variability in temporal patterns of recruitment and spawning stock were compared among functionally analogous species from four marine ecosystems including the Gulf of ...

    • Bernard Megrey: pioneer of Comparative Marine Ecosystem analyses 

      Moksness, Erlend; Link, Jason S.; Drinkwater, Ken; Gaichas, Sarah (Journal article; Peer reviewed, 2012-07-12)
      The MEPS Theme Section on ‘Comparative Analysis of Marine Fisheries Production’ is dedicated to Dr. Bernard Megrey. Dr. Megrey was well known for comparative studies of ecosystems, but his contributions to science were ...

      Multispecies models have existed in a fisheries context since at least the 1970s, but despite much exploration, advancement, and consideration of multispecies models, there remain limited examples of their operational use ...

    • Ocean futures under ocean acidification, marine protection, and changing fishing pressures explored using a worldwide suite of ecosystem models

(Journal article; Peer reviewed, 2018)
      Ecosystem-based management (EBM) of the ocean considers all impacts on and uses of marine and coastal systems. In recent years, there has been a heightened interest in EBM tools that allow testing of alternative management ...

    • Relative importance of fisheries, trophodynamic and environmental drivers in a series of marine ecosystems 

      Fu, Caihong; Gaichas, Sarah; Link, Jason S.; Bundy, Alida; Boldt, Jennifer L.; Cook, Adam M.; Gamble, Robert; Utne, Kjell R.; Liu, Hui; Friedland, Kevin (Journal article; Peer reviewed, 2012-07-12)
      Marine ecosystems are influenced by drivers that operate and interact over multiple scales, resulting in nonlinear or abrupt responses to perturbation. Because of the inherent complexity of marine ecosystems, progress ...
