Findings

Modeling and synthesis activities have focused on understanding how ecological patterns and processes in upstream freshwater Everglades marshes affect the composition of water flowing into the estuarine ecotones. Scientists used a “dynamic budget” approach to simulate ecosystem dynamics at particular locations along the Shark River Slough and Taylor Slough transects. These budgets were conceptually linked with “ribbon models,” which among other things, predicted water phosphorus concentrations.

The models successfully predicted water phosphorus concentrations within the range of observed values for all areas except the interior estuarine sawgrass marsh. Decadal output from these models showed that the highest phosphorus accumulation rates occur in sawgrass and wet prairie marshes nearest to canal inputs. The models, however, did not predict phosphorus accumulation in the estuarine interior marshes. When the models were modified to include other sources of phosphorus, model predictions improved considerably, highlighting the need for further investigations.
