  • Timeframe : 2012 -

  • Coordinator: ESE research unit, Jérôme Guitton
  • Contact: Jérôme GUITTON
  • Website
  • Keywords : Marine ecology, EwE models, Ecosystem modeling, Database server


Context and Issues


  • Ecological studies are increasingly based on data-driven methodologies that rely on pre-existing datasets. However, open-access, digital and cross-disciplinary datasets are still uncommon in ecology
  • Sharing data among ECOPATH with ECOSIM (EwE) developers has been a persistent goal, and a model depository was set up on the ECOPATH website
  • There has been a large effort to collect information from all ecosystem models worldwide built using the EwE approach




  • Establishing an up-to-date and comprehensive list of published ECOPATH models and making the models available in an online repository
  • Making ECOPATH model data, which are currently available in ECOBASE, accessible to and reusable by the EwE community


  • Merging three pre-existing lists of ECOPATH models established by Francisco Arreguín-Sánchez (CIC IMARE, Mexique), Lyne Morissette (ISMER, Canada) and Villy Christensen (UBC-Fisheries Centre, Canada)
  • Selecting only published ECOPATH models and identifying their associated references
  • Collecting metadata about the published ECOPATH models when provided in the associated references
  • Leading a discussion within the Ecopath Research and Development Consortium (ERCD) to decide which data will be made available and how (webservices)


Results and Perspectives


  • Publication of a Fisheries Centre Research Report presenting the repository (Colléter et al., 2013)
  • Presentation at the ERDC meeting (Colléter et al., 2012)
  • Use in a variety of meta-analyses
