Summary and Synthesis of the Available Literature on the Effects of Nutrients on Spring Organisms and Systems


Funding Organization: Florida Department of Environmental Protection

Principal Investigator: Mark T. Brown, Center for Environmental Policy, Center for Wetlands

Other Investigators: Matt Cohen, Jason Evans, Tom Frazer, Patrick Inglett, Kanika Inglett, Chuck Jacoby, Bob Knight, Ed Phlips, Kelly Chinners Reiss, Ramesh Reddy, Wendy Graham

Project Coordinator: Kathleen McKee, UF Water Institute

Water Institute Affiliation: WI-assisted Project

Project Background and Goals:
A report is being prepared by UF investigators for the FDEP (due March 2008) that will be a literature review intended to address the influence of rising nutrient levels on trophic dynamics and ecological processes within Florida and other regions with spring ecosystems. Synthesis of available literature (including published, peer reviewed documents and gray literature reports) will identify cause and effect relationships between nutrients and biological response at all affected trophic levels. The final, synthetic literature review will present what we know as guidance for public policy, information gaps that inject substantial uncertainty, and suggested research to address these gaps.
