Ecological implications of allelopathic interferences with reference to Phragmites australis
… as a mechanism of the invasion process in Phragmites australis by a series of ecologically realistic experiments in the laboratory, greenhouse and field.

Empirical investigation of water pollution control through use of Phragmites australis
… use of the technique of phytoremediation using Phragmites australis (PA) plants that have the capacity to absorb and to accumulate such metals in their roots and leaves. The metal uptake and their location of accumulation in the PA plants were determined using flame atomic absorption …

Effect of invasive phragmites australis and its control on microbial community composition in a freshwater wetland
… by microorganisms. Invasive plants, like Phragmites australis, reduce biodiversity and alter ecosystem services. I hypothesized that changes in soil bacterial communities would occur after Phragmites invasion and restoration efforts employing herbicide to remove Phragmites would further …

Heavy metal phytotoxicity: the effects of lead on the common reed, Phragmites australis (Cav.) Trin. ex Steud.
… examined the effects of Pb on the life cycle of Phragmites australis (Cav.) Trin. ex Steud (common reed) as increased plant productivity is thought to be integral to the metal removal process. Hydroponic gravel-based mesocosms planted with vegetative reed propagules were regularly dosed with 50 …

Effects of invasion by the common reed (<i>phragmites australis</i>) on carbon transformations in a Great Lakes marsh
<p>The common reed (<em>Phragmites australis</em>) is a highly productive invasive grass that alters the wetland physiochemical environment and produces toxic secondary metabolites. Plant litter decomposition, effects of water level on soil microbes, and soil microbial response to leachate …

Ecophysiological effects of high concentrations of iron and other heavy metals on Eriophorum angustifolium Honck. and Phragmites australis (Cav.) Trin ex steudel.
… and uptake b y Eriophorum augustifolium, and Phragmites australis taken from mine populations (Parys Mountain, Anglesey and Crymlyn Bog , Swansea) and a non-mine population (Skipwith Common, Yorks) and to provide information on the resistance of these two species to high concentrations of Fe …

Produzione di biomasse energetiche irrigate con acque reflue depurate tramite sistemi di fitodepurazione
… Lytrum salicaria (L.), Typha latifolia (L.), Phragmites australis (Cav.) Trin. ex Steudel e Sorghum bicolour (L.) Moench irrigate con le acque reflue depurate da un adiacente impianto di fitodepurazione che effettua il trattamento terziario di parte dei reflui prodotti da un piccolo centro …

A comparison of Nebo Hill and Sedalia points
… The relationship between the distribution of Phragmites australis, or common reed, and Nebo Hill points offers an explanation for the change in form founded on a possible intensification in the occurrence of socket hafting.

Application of the ³H-Leucine incorporation technique for quantifying rates of bacterial secondary production associated with decaying wetland plant litter
… <em>Schoenoplectus validus</em>, and <em>Phragmites australis</em>. Incorporation of 3H-leucine into protein exhibited a biphasic saturation curve, with lower apparent K<sub>m</sub> values ranging from 400 nM to 4.2 μM. Upper apparent K<sub>m</sub> values ranged from 1.3 to 21.7 μM. These …

Herbicide management alters fungal biomass and community composition in Great Lakes coastal wetlands
… but less is known about how soils respond. Phragmites australis, an invasive wetland plant, can alter soil conditions, potentially impacting soil microbial structure and function. We sampled soil communities in Great Lakes coastal wetlands in southeastern Michigan dominated by Phragmites and …

Drivers and Impacts of Smoldering Peat Fires in the Great Dismal Swamp
… we quantified the abundance of the noxious Phragmites australis in a large fire scar and the extent to which altered hydrology influenced its occurrence. We did so by leveraging satellite imagery, random forest models, LiDAR data, and water table observations. Our results suggest that P. …

Uptake and growth effects of polycyclic aromatic hydrocarbons in wetland plants
… salt marsh plant species, Spartina alterniflora, Phragmites australis, Solidago sempervirens and Distichlis spicata were grown in pots of PAH contaminated sediment containing mean total PAH concentrations of 355 mg/kg (ppm). During the growing season, the plant height, aboveground biomass, percent …

Remote Sensing Methods To Classify a Desert Wetland
… The marsh is dominated by Typha domengensis with Phragmites australis as a sub-dominant species in shallower marsh areas. The most important factor controlling vegetation density was fire. The second significant (P<0.01) factor controlling NDVI was flow rate of agricultural drain water from the …

Tidal Wetland Inundation and Vegetation Phenology from Space: A Synthesis of Approaches for Characterizing Ecological Status and Inundation Dynamics in Tidal Wetlands with Remote Sensing Observations
… also map marshes that have been invaded by <em>Phragmites australis</em>. These three types of marshes were all mapped with greater than 80% user’s and producer’s accuracy in the Mid-Atlantic region. This marsh mapping effort was also carried out in the Gulf Coast region, where marshes were …

Humedales construidos de flujo subsuperficial horizontal para remoción de arsénico y hierro: Asociación y fraccionamiento en la fase sólida
… tipos de celdas según la presencia o ausencia de Phragmites australis, y tipo de sustrato: piedra caliza o zeolita. El fraccionamiento se obtuvo a través del procedimiento de extracción secuencial propuesto por Tessier (1979), consistente en cinco fases: intercambiable, carbonatos, óxidos, materia …

Floating treatment wetlands for synthetic greywaterremediation
… artificially retrofitted with floating reedbed Phragmites australis to introduce, what isknown as, floating treatment wetlands (FTWs) for improving the removal efficiency of soluble contaminations from synthetic greywater (SGW) in such systems. As a corroboration to the phytoremediation, …

Biogeographical Approaches for Studying Species Invasion
… enhancing invasion of introduced genotypes of Phragmites australis along the coastal wetlands of North America. I tested the hypotheses that large-scale disturbance events, such as hurricanes and tropical storms, enhance the invasion success of introduced P. australis in North America. The …
