This study explores ibuprofen (IBP) uptake and transformation in the wetland plant species Phragmites australis and the underlying mechanisms. We grew P. australis in perlite under greenhouse conditions and treated plants with 60 μg/L of IBP. Roots and rhizomes (RR), stems and leaves (SL), and liquid samples were collected during 21 days of exposure. Results show that P. australis can take up, ...

In the recent article, “Managing Invasive Aquatic Plants in a Changing System: Strategic Consideration of Ecosystem Services,” Hershner and Havens (2008) reject the need to manage certain aquatic plant invaders. The authors claim that Phragmites australis invasion is acceptable because it provides three ecosystem services: habitat, soil stabilization, and nutrient uptake and retention. We stron...

Biogenic silica (BSi) contents in the marsh plants (Phragmites australis, Scirpus mariqueter and Spartina alterniflora) and associated sediments in Chongming Island eastern intertidal flat of the Yangtze Estuary were determined. The BSi contents in P. australis, S. mariqueter and S. alterniflora varied from 25.78-42.74 mg/g, 5.71-19.53 mg/g and 6.71-8.92 mg/g, respectively. Over the entire grow...

Hydrological conditions determine the distribution of plant species in wetlands, where conditions such as water depth and hydrological fluctuations are expected to affect the interspecific interactions among emergent wetland species. To test such effects, we conducted a greenhouse experiment with three treatment categories, interspecific interaction (mixed culture or monoculture), water depth (...

Variation in ploidy levels in Phragmites australis is a welldocumented phenomenon although North American populations are less studied than European ones. It has been suggested, based on morphological measurements, that native and introduced P. australis subspecies in North America represent different ploidy levels. The objectives of this study were to assess whether guard cell size and stomata...

A diverse Diptera assemblage, dominated by the family Chloropidae, is associated with common reed (Phragmites australis (Cav.) Trin. ex Steudel, Poaceae) in the Palearctic region (Tewksbury et al. 2002). Although P. australis has long been present in North America, many of its associated Chloropidae have remained restricted to the Palearctic. The best-known chloropid associates of Phragmites ar...

BACKGROUND AND AIMS We review evidence for hybridization of Phragmites australis in North America and the implications for the persistence of native P. australis ssp. americanus populations in North America. We also highlight the need for an updated classification system, which takes P. australis intraspecific variation and hybridization into account. METHODOLOGY We reviewed available publish...

The genetic and epigenetic diversity and structure of naturally occurring Phragmites australis populations occupying two different habitats on a small spatial scale in the Songnen Prairie in northeastern China were investigated by assessing amplified fragment length polymorphisms (AFLPs) and methylation-sensitive amplified polymorphisms (MSAPs) through fluorescent capillary detection. The two g...

Phragmites australis is the dominant and constructive species among plant communities in the wetlands of the downstream of Yellow River, China. Its morphological characters were high variable in different habitats. Studies on Morphological and RAPD variation of 15 P. australis populations from this region showed that soil salinity was the dominant ecological factor that affected the morphologic...
