Summary: The study found that young plants in the rapid growth stage contain the highest levels of total nitrogen and total phosphorus, while the leaves of common reeds have a higher capacity for nitrogen phytoaccumulation. The surface layer of the filtration material in constructed wetland beds has the highest content of total nitrogen and total phosphorus, with accumulation decreasing with depth and outflow direction of sewage.

Summary: In this study, the distribution of Phragmites australis in the Momoge Ramsar Wetland site was successfully mapped using the random forest method and Sentinel-1/2 images. Multiple linear regression models were used to estimate the aboveground biomass of Phragmites australis. The findings highlight the significance of the Sentinel-2 red-edge band in improving the accuracy of biomass estimation.

Summary: The study found that subsurface horizontal flow constructed wetlands (SSF-CW) are more effective in treating wastewater compared to surface horizontal flow constructed wetlands (SF-CW), especially in terms of pollutant removal and reduction in microbial load. Additionally, SSF-CW exhibited higher values in atmospheric evapotranspiration and harvestable biomass of Phragmites.

Summary: The study found that wetland nitrogen removal is affected during the plant wilting period, and balancing the tradeoff between nitrogen removal and wetland sustainability can be achieved by choosing the optimal harvest time. Results showed that late harvest time reduces nitrogen removal, and the impact of harvest time on plant nutrient response varies in different years.

Summary: This study investigated the response of Phragmites australis populations to inundation depth and its impact on clonal plants' phenotypic variability. The results showed a negative correlation between inundation depth and shoot height, leaf length, leaf width, leaf biomass, and panicle length. Leaf parameters exhibited a higher coefficient of variation and played a crucial role in the action of plants during floods. Population differentiation was consistent with geographical distance and morphological similarity.

Summary: Macrophyte rhizosphere microbes play a crucial role in wetland ecosystems, and their composition and function are affected by environmental conditions and management practices. This study characterized the bacterial community of the rhizosphere and bulk sediments of Phragmites australis in natural and constructed wetlands. The results showed higher diversity in the bacterial community of the constructed wetland compared to the natural wetland. Specific functional bacterial groups were enriched in the rhizosphere of each wetland type. Co-occurrence network analysis revealed more complex interactions among bacterial taxa in the constructed wetland. These findings contribute to our understanding of macrophyte rhizosphere-associated microbes and their interactions in different wetland types.

Summary: Continuous phosphorus discharges in bodies of water, generated by human activities, produce contaminated water and eutrophication. Efficient and low-cost systems are necessary to remove phosphorus. Generating renewable energy from biomass waste, and using resulting ash for phosphorus removal, is important. Reed ash has been proven to effectively improve water quality.

Summary: Constructed wetlands (CWs) have been proven to be a cost-effective alternative for treating mine waters. In this study, a pilot-scale wetland was implemented to treat alkaline bauxite residue leachate, and after 5.5 years of operation, the CW effectively reduced the influent pH from 11.5 to 7.8. Trace element analysis showed a significant reduction in Al, As, and V, with sediment analysis revealing an accumulation of elevated pH and trace element content in the first 5 meters of the wetland. The investigation into microbial communities highlighted the importance of further research in alkaline CWs.

Summary: The presence of arbuscular mycorrhizal fungal (AMF) enhanced the tolerance of Glyceria maxima to ibuprofen (IBU) and diclofenac (DCF) stress in constructed wetlands, by promoting antioxidant enzyme activities and soluble protein content. The addition of adsorptive substrates increased the removal efficiencies of IBU and DCF, while AMF influenced their reduction based on different substrates. These findings suggest that AMF and adsorptive substrates can be useful in enhancing the removal of contaminants in constructed wetlands.

Summary: Floating treatment wetlands (FTWs) are an innovative and economical way of wastewater treatment using hydroponically grown emergent plants. This study evaluated the performance of FTWs using Canna indica and Phragmites australis for municipal wastewater treatment. Results showed that Phragmites australis performed well in organic matter removal, while Canna indica was effective in nutrient removal, particularly NO3- from wastewater.

Summary: Restoration efforts in river deltas often involve using dredged sediments to improve ecological value. This study examined the development of cattail and common reed on two types of dredged sediments, clay and mud, under different water levels in a mesocosm experiment. The results showed that sediment type influenced the growth of cattail, while water level only affected the development of common reed under inundation conditions. Both sediment types were suitable for macrophyte vegetation development.

Summary: Polyploidization in plants is considered as a mechanism to cope with environmental stresses. Gene networks involved in differentially expressed genes play a role in driving adaptation through the evolution of unique phenotypic traits. Phragmites australis, a species with highly variable phenotypic traits and adaptation capacity, shows varying ploidy levels, making it a suitable organism to study the molecular evolution of polyploidy. By using RNAseq data, this study identified genetic differences between tetraploid and octoploid P. australis, shedding light on how polyploidization influences environmental responses and stress tolerance in grass species.

Summary: This study characterized the bacterial communities associated with P. australis, soils, and permeates in an artificial wetland in Italy using next-generation sequencing. The results showed that P. australis has a specific microbiota that remains consistent across different plant tissues and over time. This ability allows P. australis to survive in the hostile environment of artificial wetlands.
