A MODEL SIMULATING INTERACTIONS BETWEEN HYDROLOGY, LANDSCAPE, SPECIES TRAITS AND BIOTIC INTERACTIONS TO PREDICT DAM IMPACTS ON RIVER-FLOODPLAIN SYSTEMS
Understanding community dynamics is challenging because species respond differently to environmental conditions while interacting within networks of interactions with other species. Most food web models portray species populations or guilds as aggregate units, and thus have no capability to capture important interactions of organisms with their abiotic and biotic environments. This is a major shortcoming, because organism functional traits are known to have strong influences on population dynamics and population interactions. Building on previous research on individual-based modeling, we constructed a model that simulates fish population and food web dynamics for the last major un-dammed reach of the Upper Paraná River in Brazil. This model uses topographic information and hydrologic data to produce spatially explicit dynamics of food webs. The model incorporates general functions for biological processes and functional traits of species to simulate organism performance and population dynamics. Model calibration and validation instill confidence that the tool is sufficiently flexible to allow modifications to simulate other lotic systems, including rivers in the Amazon and other tropical regions impacted by hydroelectric dams. Simulation of hydrologic, land-use, and fishery scenarios will inform natural resource conservation.
