    1313A good modelling tactic is to try both approaches and see whether they give different answers.  However, note that the first approach can lead to misleading answers upon entry to Ecospace, if the Ecospace mapped area includes the ‘outside’ system: in that case, the model will continue to ‘import’ part of the diet and food consumption of migratory species.  Thus when the model development plan includes use of Ecospace to represent a larger spatial system, the functional group organization for that larger system needs to be included in the initial Ecopath/Ecosim model definition (approach 2).

    15 It is possible to incorporate migration in Ecospace by defining which groups migrate and where their concentration is by month, see [[Representing seasonal migration.htm|Representing seasonal migration in Ecospace]] for further information.
