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 …

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 …

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 …

Pheasant Use of Wetlands During The Winter and Application of Landsat Imagery For Assessing Winter Habitat
… over other cover types for loafing. Trees, phragmites (Phragmites communis), and cattails (Typha latifolia) were also used regularly. Smartweeds (Polygonum coccineum), roundstem bulrushes (Scirpus acutus and Scirpus validus), and grasses were seldom used. Density was the most important …

Lake Erie coastal marsh aquatic invertebrate community structure across habitats dominated by two different emergent macrophytes
… communities between areas dominated by<em> Phragmites australis</em> and areas dominated by <em>Typha spp</em>. in a freshwater coastal marsh. The hypothesis was that aquatic invertebrate diversity and abundance would be greater in <em>Typha</em>-dominated locations as opposed to …

Behavior, Nest Site Selection and Success of Black Terns (Chlidonias niger)
… by non-native plant species including <em>Phragmites</em>, hybrid and narrow-leaved cattail (<em>Typha</em> spp.), and European frog-bit (<em>Hydrocharis morus-ranae</em>). Statistically significant differences (<em>P</em> < 0.05) were observed between the average percent cover of submerged …

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 …

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 …

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.

Strawberries (Frag X Anan) Are Bigger When Native Mason Bees (Osmia lignaria) Are Experimentally Added to Small Farms
… homes made with different materials (bamboo, <em>Phragmites</em>, or wood) were supplemented on a side of each of nine family-owned farms. Fruit volumes were compared between treatment and the control sides of the farms where no additions were made. Mean strawberry volumes were greater and had …

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 …

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. …

Spatial modeling and visualization of habitat response to hydrologic restoration in New England salt marshes
… Juncus gerardii, and brackish invasive species Phragmites austrahs, Typha angustifolia, and Lythrum salicaria .</p><p>The model was applied to spatial grids representing marsh area at four salt marsh sites with past or current impacts due to restricted tidal flows. At each site, field data for …
