Short-term uptake of heavy metals by periphyton algae
The utilization of periphyton activity for the removal of heavy metals from enriched small streams has been examined. By means of short-term batch laboratory experiments the courses of metal uptake have been s...

Zn uptake by Cladophora glomerata
The uptake of zinc by Cladophora glomerata at different pH-values, light conditions and exposure periods is reported. Zinc uptake was pH-dependent, with uptake increasing with rising pH. Uptake was greatest withi...

The use of periphyton communities for nutrient removal from polluted streams
The results of experiments on the efficiency of periphyton communities for nutrient removal from polluted streams in a continuous flow-through are given. The artifical stream (5 m × 0.7 m × 0.5 m) was made of ...

Response of everglades plant communities to nitrogen and phosphorus additions
Nitrogen(N) and phosphorus(P) were applied to sawgrass (Cladium jamaicense), mixed sawgrass-cattail (Typha domingensis), and slough (shallow water communities dominated byUtricularia spp.,Eleocharis spp., andPani...

Subsurface horizontal-flow constructed wetlands for wastewater treatment: The Czech experience
The first full-scale constructed wetland (CW) in the Czech Republic was built in 1989 and there are now three tertiary systems and 50 secondary treatment facilities. We report here on the design and operationa...

Removal of Phosphorus in Constructed Wetlands with Horizontal Sub-Surface Flow in the Czech Republic
The major processes responsible for phosphorus (P) removal in constructed wetlands with horizontal sub-surface flow (HSF CWs) are adsorption, precipitation and plant uptake if the biomass is harvested. The fil...

Constructed Wetlands for Wastewater Treatment
Constructed wetlands have been used for wastewater treatment for nearly 40 years and have become a widely accepted technology available to deal with both point and non-point sources of water pollution. They of...

Algal Responses to Long-Term Nutrient Additions
Periphyton is an important part of the food web and is an integral part of the Everglades ecosystem (Wood and Maynard 1974; Browder et al. 1982). During the late summer and fall, thick mats floating at the sur...

Chapter
Experimental Assessment of Phosphorus Effects on Algal Assemblages in Dosing Mesocosms
Periphyton covered by calcareous precipitations in the Everglades is mostly dominated by cyanobacteria (Cyanoprokaryota, blue-green algae). In some areas of the Everglades, diatoms, desmids, and a few species ...

Macrophyte Slough Community Response to Experimental Phosphorus Enrichment and Periphyton Removal
In this chapter, we will present evidence that may help in explaining the general pattern of response of wetland macrophyte communities to eutrophication, light, and competition as well as assess changes in pl...

Plant Community Response to Long-Term N and P Fertilization
The objective of the Duke N and P fertilizer study in three Everglades plant communities (sawgrass, mixed sawgrass–cattail, and slough) was to determine the long-term (>6 years) effects of fertilizer additions...

Macrophyte Community Responses in the Everglades with an Emphasis on Cattail (Typha domingensis) and Sawgrass (Cladium jamaicense) Interactions along a Gradient of Long-Term Nutrient Additions, Altered Hydroperiod, and Fire
Collectively, these studies suggest that multiple factors are responsible for the alteration and maintenance of plant community structure in the Everglades (Fig. 9.1). Historically, the primary factor controll...

Enrichment Gradients in WCA-2A and Northern WCA-3A: Water, Soil, Plant Biomass, and Nutrient Storage Responses
Increases in cation (e.g., Ca2+, Na+, and Mg2+) and anion (e.g., Cl? and NO? 3) concentrations have been documented throughout the greater Everglades ecosystem (SFWMD 2004, 2005, 2006). In particular, concerns...

Removal of nitrogen in constructed wetlands with horizontal sub-sureface flow: a review
The paper describes the removal of nitrogen in horizontal sub-surface flow constructed wetlands (HF CWs) for various types of wastewater. The survey includes more than 900 annual means from more than 300 syste...
