Scientific and Technical Support for Joint Ecosystem Modeling
The concept of a Joint Ecosystem Modeling Laboratory (JEM) was conceived of by Drs. G. Ronnie Best, Frank J. Mazzotti, and Don D. DeAngelis as a potential mechanism for "Getting Models in the Hands of the Users". JEM has evolved since then as an informal partnership of DOI agencies, (USGS/FWS/NPS), Universities, and others supporting a variety of tasks for development of ecological models as well as integration with hydrologic models, development of decision support tools, and science communication through visualization tools and written documents. A part of that evolution was the development of a cooperative agreement with University of Florida to facilitate research and development of ecological models with the ultimate outcome of getting them in the hands of the users. Work was accomplished by University of Florida staff and via subcontracts to other Universities and organizations. A major benefit of this agreement was that it provided the base for leveraging resources to work with others to develop and test models. This site summarizes the work completed directly under a five year cooperative agreement between University of Florida and USGS. Additional activities have been undertaken by JEM since the original agreement. See http://jem.cr.usgs.gov/pages/home.aspx for more information on the ongoing projects.
Development of ecological models includes a range of steps including determining user needs, collecting ecological data, developing decision rules, developing model structure, implementation of decision rules in a technically robust manner, performing initial scenario evaluations and interpretation as part of the process of testing, calibrating, validating, verifying, and improving models, as well as developing visualization and decision analysis tools.
Major accomplishments of this project include:
- Development or modifications to 14 ecological models with documentation.
- Eight of the 14 models were reviewed and approved by the Interagency Modeling Center (IMC) and used in project planning in southwest Florida.
- A prototype dataviewer was used successfully in the C-43 project planning process and evolved to the JEM dataviewer which has since been replaced by EverView.
- Four Everglades Depth Estimation (EDEN) tools were developed to assist users in accessing EDEN data.
- Six Across Trophic Level Spatial Simulation (ATLSS) Spatial Explicit Species Index (SESI) models were delivered to the IMC.
- An ATLSS Topography/Hydrology Handbook was produced and delivered to DOI partners and the IMC.
- Four refereed publications, 1 masters thesis, 1 PhD dissertation, 13 technical reports, six fact sheets, and 26 presentations were produced by core University of Florida staff.
- Coordination occurred with a range of partners via workshops and meetings.
- Administration of subcontracts to eight individuals resulted in numerous other reports and products.
