EwE is a free ecological/ecosystem modeling software suite.  It can be used to address ecological questions; evaluate ecosystem effects of fishing; explore management policy options; analyze impact and placement of marine protected areas; predict movement and accumulation of contaminants and tracers (Ecotracer); and model effect of environmental changes. This presentation will provide an overview of the latest version of EwE and describe a new zoning tool, Ecoseed, that is being developed for the EwE software package through the MEBM Tool Innovation Fund.  Ecoseed is designed to evaluate placement of protected areas.  For more information about EwE, go to www.ecopath.org.  For more information about the Ecoseed project, go to http://mgel.env.duke.edu/proj/mebm/funded-projects/ecoseed.
