Project Summary Sheet
Fiscal Year 2004 Study Summary Report
Study Title: Computer Simulation Modeling of Intermediate Trophic Levels for Across Trophic Level Systems Simulation of the Everglades/Big Cypress Region
Overview & Objectives: This project has had the goal of developing models for key components of the Everglades landscape as part of the overall Across Trophic Level System Simulation. Past research has developed the basic model for freshwater fish biomass and a model of energy flow in the reptile and amphibian community. Current work has involved modeling and empirical studies on the American crocodile, the snail kite, small mammals, and the oak toad. The objectives have been to understand the effects of hydrologic conditions on each of these taxa.
Status: Additional CESI money has been added to fund the project until 12/31/2005
Crocodile modeling and empirical work: Paper is in press on the crocodile individual-based model.
Small mammal field work: This past work has given us insight into the effects of interactions with biotic and abiotic factors. Our previous work has given us a better understanding of the role of hydroperiods on the patch dynamics of the two most prominent small mammal species, the silver rice rat (Oryzomys palustris) and the cotton rat (Sigmodon hispidus)
