Population levels of aquatic species vary greatly between the wet and dry seasons but factors that influence those fluctuations required study, particularly the effects of water-management structures and operations. Focusing on several small fishes, grass shrimp, and Florida gar, this study endeavored to answer some outstanding questions of importance to Everglades restoration. Specifically, the project used both radio telemetry and genetic surveys to monitor the movements of both predator and prey species. The results shed considerable light on the influences of nearby canals and water-management practices. Please contact us for a copy of this report RELATED PUBLICATIONS Collins, T. M., Trexler, J.
