Eutrophication continues to impact watersheds and their receiving water bodies. One approach to mitigate this problem is to use constructed treatment wetlands. Our objectives were to determine long-term phosphorus (P) removal by a large-scale constru

We propose a framework for lake management that accounts for inherent variation in ecosystem state and extends the Hutchinsonian niche concept to the ecosystem level. Analogous to the n-dimensional species niche, the ecosystem state “niche” is en

Nitrogen loss from landscapes affects downstream freshwater and marine systems. Constructed wetlands, which are ecologically-engineered systems, can mitigate nitrogen loss from various landscape types. We examined the efficacy of a large-scale constr

Constructed wetlands treat various types of waters. We examined the efficacy of a large-scale constructed wetland (the marsh flow-way), which was designed to treat lake water by maximizing the removal rate of total phosphorus (TP), and total suspende

We removed gizzard shad (GS; Dorosoma cepedianum) from Lake Denham, a 104 ha hypereutrophic lake in the Ocklawaha chain of lakes in central Florida, to evaluate biomanipulation for restoration of shallow hypereutrophic Florida lakes. A commercial hau

R. A. Vollenweider applied the principle of parsimony to develop models of lake trophic state that cut through the considerable complexities of lake ecosystems. Based on the mass balance of phosphorus, these models reduced the complex aquatic biogeoc

Summary 1. The St. Johns River Water Management District removed over 5.4 million kg of gizzard shad (Dorosoma cepedianum) from Lake Apopka, FL during 1993–2005, as a means of reducing lake phosphorus and phytoplankton concentrations and improving

Controversy exists about the historic shift of primary producer community structure (PPCS) in Lake Apopka, a shallow, 125-km2 lake in central Florida, U.S.A. The controversial questions are: was a lake-wide shift from macrophyte to phytoplankton domi

We developed empirical models that can predict maximum allowable, nutrient loading rates or load limits (LM) for maintenance of mesotrophy in Florida’s fresh and estuarine waters. Water residence time (tw) explains most of the variation in LM previ

The St. Johns River Water Management District (SJRWMD) has developed a minimum flows and levels (MFLs) method that has been applied to rivers, lakes, wetlands, and springs. The method is primarily focused on ecological protection to ensure systems me
