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

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

The purposes of this study were to assess if Lake Apopka (FL, USA) was autotrophic or heterotrophic based on the partial pressure of dissolved carbon dioxide (pCO2) in the surface water and to evaluate factors that influence the long-term changes in

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 found the conclusion of SCHELSKE et al. (2003, Arch. Hydrobiol. 157:145-172) that Lake Apopka was not net heterotrophic was incorrect when annual rates of production and respiration for the entire lake ecosystem are taken into consideration. A new

Summary 1. Lake Apopka (FL, U.S.A.) was subjected to decades of high nutrient loading from farms developed in the 1940s on converted riparian wetlands. Consequences included perennially high densities of cyanobacteria, low water transparency, elimina
