1 Across Trophic Level System Simulation (ATLSS)
USGS and University of Tennessee at Knoxville Institute for Environmental Modeling atlss.org Objective ATLSS projects the outcomes of future hydrologic scenarios on the biological components of south Florida terrestrial and wetland upper trophic systems. It is based on surface and groundwater hydrological models and biological submodels for plants and animals. It was designed to evaluate Everglades restoration strategies. Key Assumptions of Hydrologic Model Hydroperiod ranges estimated from published literature and expert opinion, Temporal/Spatial Scale 5-day timestep/spatially defined at 500 x 500m

2 Input Drivers Key Outputs
MESH CELL IS THE UNIT OF THE LANDSCAPE HYDROLOGY MODEL Evapotranspiration Rainfall Wind Sheltering Effect of Vegetation and Microtopography on Overland Flow Key Outputs Spatial and temporal distribution of animals Produces population relative mortality, reproduction, individual movement, territory size Predict fish biomass to assess prey availability for wading birds

3 Cape Sable Seaside Sparrow Breeding Potential
Hydrological output is verified from field inspections, independently computed values and function testing
