Heavy Metals in Wetlands in Turkey
Wetland areas are one of the most precious ecosystem because they contain rare ecological assets. The total area of wetlands of Turkey is 9.861 km2 and wetlands cover 1.2% of total area of Turkey. Unfortunately, ...

Field Study VI: The Effect of Loading Strategies on Removal Efficiencies of a Hybrid Constructed Wetland Treating Mixed Domestic and Agro-Industrial Wastewaters
The treatment of domestic wastewater using constructed wetlands (CWs) is common in the Czech Republic; however, the treatment of agro-industrial wastewater is still at the beginning of its application. A hybri...

Chapter
Transformation of Chloroform in Constructed Wetlands
Chloroform is a volatile organic contaminate widely detected in groundwater, surface water and wastewater effluent, thus its fate in the natural treatment systems is of great importance to the environment and ...

Distribution of Phosphorus and Nitrogen in Phragmites australis Aboveground Biomass
The objective of this study was to evaluate nitrogen and phosphorus compartmentalization in the aboveground biomass of Phragmites australis and its seasonality. The study was carried out at four sites in the litt...

Chapter
Treatment of Chlorinated Benzenes in Different Pilot Scale Constructed Wetlands
Chlorinated benzenes (CBs) are common pollutants in groundwater due to their broad usage in industry and agriculture. Remediation of CBs from contaminated groundwater is of great importance. Biodegradation has...

Chapter
Decomposition of Phragmites australis in Relation to Depth of Flooding
Decomposition of Phragmites australis in relation to water depth was studied in the littoral reed stands of two fishponds near Prague during 2014. In both fishponds, three sites were selected along the water dept...

Chapter
Does the Presence of Weedy Species Affect the Treatment Efficiency in Constructed Wetlands with Horizontal Subsurface Flow?
In the Czech Republic, Phalaris arundinacea and Phragmites australis are two most frequent plants used in constructed wetlands for wastewater treatment. While Phragmites is quite resistant to the invasion of othe...

Chapter
Constructed Wetlands in the Czech Republic: 20 Years of Experience
Constructed wetlands (CWs) have been used in the Czech Republic since 1989. At present, about 250 systems are in operation. All systems have been designed with horizontal subsurface flow and most CWs have been...

Chapter
Nutrient Accumulation by Phragmites australis and Phalaris arundinacea Growing in Two Constructed Wetlands for Wastewater Treatment
Phragmites australis and Phalaris arundinacea are two most commonly used plants in constructed wetlands for wastewater treatment in the Czech Republic. This chapter deals with development of biomass,...

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 ...

Chapter
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...

Chapter
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...

Chapter
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...

Chapter
Vegetation and Algae of the Everglades Fen
The objectives of this chapter are to briefly review the species composition of plant communities in the Florida Everglades as well as present an assessment of aboveand belowground biomass for each plant commu...

Chapter
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...

Chapter
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...

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...
