This work presents the research carried out to determine the natural durability of reed (Phragmites communis) from the Fertö region of Hungary against wood decay organisms, with the objective of obtaininig information to be used as a constituent element in outdoor use, and in particular, in a viable and sustainable motorway noise barrier. Phragmites communis is a large perennial grass of consid...

Wastewaters from leather processing are very complex and lead to water pollution if discharged untreated, especially due to its high organic loading. In this study the survival of different plant species in subsurface horizontal flow constructed wetlands receiving tannery wastewater was investigated. Five pilot units were vegetated with Canna indica, Typha latifolia, Phragmites australis, Steno...

Abundance and diet of larger predatory fishes in Phragmitesmarsh creeks were compared with those in natural Spartina alterniflora marshes and Phragmites marshes exposed to herbicides and burning (treated marshes). The most abundant fishes (n=3,107) caught in gill nets from June to November 2001 and May to November 2002 were Morone americana (white perch; 82%) and Ictalurus punctatus (channel ca...

one of the most important methods to investigate heavy metals as pollutants is more likely to use bio-monitors which can be applied as an appropriate index to express the quality of environment. in current study, in order to investigate the effects of dominant plants in the desired region and role of aquatic macrophytes in monitoring such elements as zinc (zn), lead (pb), copper (cu) and cadmiu...

the concentration of three metals, zinc, copper and chromium in roots, rhizomes, stems and leaves of phragmites australis (common reed) and scirpus maritimus, and in the corresponding sediment and water samples from lia industrial area (qazvin, iran) were investigated to determine difference in distribution among plant organs. data were collected at during 1-year period. results showed that met...

Soil disturbance has been widely recognized as an important factor influencing the structure and dynamics of plant communities. Although soil reworkers were shown to increase habitat complexity and raise the risk of plant invasion, their role in regulating the interactions between native and invasive species remains unclear. We proposed that crab activities, via improving soil nitrogen availabi...

Pomacea canaliculata (Ampullariidae) has extensively invaded most Asian constructed wetlands and its massive herbivory of macrophytes has become a major cause of ecosystem dysfunctioning of these restored habitats. We conducted non-choice laboratory feeding experiments of P. canaliculata using five common macrophyte species in constructed wetlands including Ipomoea aquatica, Commelina communis,...

Phragmites australis (an invasive plant in North America) was used as feedstock for ABE (acetone-butanol-ethanol) fermentation by Clostridium saccharobutylicum. Sulphuric acid pretreated phragmites hydrolysate (SAEH) without detoxification inhibited butanol production (0.73 g/L butanol from 30 g/L sugars). The treatment of SAEH with resin L-493 prior the fermentation resulted in no inhibitory e...

During a study on the occurrence and pathogenicity of oomycetes in the reed-belt (Phragmites australis) of Lake Constance (Germany), a new Pythium resembling the important cereal pathogen species complex P. arrhenomanes/P. graminicola was consistently isolated from necrotic mature reed leaves and reed rhizosphere samples. The new species proved to be significantly more aggressive towards reed l...

Phragmites communis Trin. (common reed) is a recognized model plant for studying its adaptation to contrasting and harsh environments. To understand the inherent molecular basis for its remarkable resistance to combined stresses, we performed a comprehensive proteomic analysis of the leaf proteins from two ecotypes, i.e. swamp and desert dune, naturally growing in the desert region of northwest...
