Susan Cormier, Ph.D., National Center for Environmental Assessment, U.S. EPA

Because aquatic communities have evolved within particular ionic tolerance ranges, the loss of species can be predicted when concentrations change.  This presentation provides an overview of the characterization of ionic tolerances as they relate to the prediction of the extirpation of benthic invertebrates with increased specific conductivity (SC).  Next, it describes how natural background affects those predictions and describes a model for predicting the level of SC associated with extirpation of 5% of benthic invertebrate genera.  Finally, research ideas will be outlined for developing models to predict biotic effects associated with increased SC associated with drought.
