background: natural methods of wastewater treatment, such as wetlands, are simple, cheap and acceptable for developing countries, especially small and remote cities. the aim of this study was to evaluate the efficiency of typha latifolica in subsurface flow constructed wetland for wastewater treatment. methods: in this experimental research, the efficiency of typha latifolica in subsurface flow...

Cattail or Typha, an emergent aquatic macrophyte widely distributed in lakes and other shallow water areas, has slender blades with a chiral morphology. The wind-resilient Typha blades can produce distinct hydraulic resistance for ecosystem functions. However, their stem may rupture and dislodge in excessive wind drag. In this paper, we combine fluid dynamics simulations and experimental measur...

The purpose of this study is to examine the potential use of anaerobic baffled reactor (ABR) followed by Bio-rack wetland planted with Phragmites sp. and Typha sp. for treating domestic wastewater generated by small communities (751 mg COD/L, 500 SCOD mg/L, 348 mg BOD5/L). Two parallel laboratory-scale models showed that the process planted with Phragmites sp. and Typha sp. are capable of remov...

A shift in plant communities of the Water Conservation Areas (WCAs) within the Everglades has been linked to changes in hydrology and high levels of nutrient loading from surrounding agicultural areas. This has resulted in the encroachment of dense cattail stands (Typha domingensis) into areas that had previously been a ridge and slough landscape populated primarily by native sawgrass (Cladium ...

BACKGROUND AND AIMS The latitudinal differences in the growth characteristics of Typha are largely unknown, although a number of studies have pointed out the effects of climate on the growth and productivity of Typha. Therefore, a dynamic growth model was developed for Typha to examine the effects of latitudinal changes in temperature and radiation on partitioning of the total biomass during th...

We investigated the use of stable C and N isotopic ratios as indicators of shifts in nutrient limitation of aquatic macrophytes in native Typha (Typha domingensis Pers.) and Cladium (Cladium jamaicense Crantz) communities growing along the well-established phosphorus enrichment gradient of Water Conservation Area 2A of the Florida Everglades. Both Typha and Cladium had significantly different d...

Many wetlands of the Great Lakes region are increasingly dominated by species of cattails, including the native Typha latifolia, the introduced Typha angustifolia, and their hybrid Typha glauca. Cattails are observed to form dense stands of live and dead biomass that may reduce plant diversity and compromise wetland habitat value. Cattail expansion has been used as an indicator of environmental...

-Phragmites austrailis have been commonly planted on sludge treatment wetlands due to its high resistance to sludge waste; thus sludge treatment wetlands are commonly referred to as “reed beds”. Phragmites’ aggressive nature and high productivity allow this invasive plant species to form monoculture stands, alter ecosystem processes, outcompete and replace native species. Thus, native alternati...
