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: Phragmites australis, a globally distributed wetland plant, plays a significant role in channel sedimentation in the distributary channels of the Mississippi River Delta. Its dieback, along with other factors like sea-level rise and subsidence, can impact sedimentation patterns in complex deltas. River managers in Louisiana may benefit from new models and data to help make decisions on how to respond to Phragmites dieback effectively.

Summary: The introduction of Phragmites has led to changes in soil microbial community composition in Suncheon Bay, Republic of Korea. The water content, pH, and dissolved organic carbon content in the soil increased. The abundance of certain microbial biomarkers was higher in Phragmites-vegetated marshes compared to other salt marshes.

Summary: Peatlands are important for carbon sequestration, but drained peatlands contribute to carbon emissions. Rewetting drained peatlands can reduce emissions and create new carbon sinks, but alternative agriculture schemes are needed. Remote sensing, especially with hyperspectral images, can be used to monitor the vegetation composition of rewetted peatland areas.

Summary: This study examines the efficacy of a voting-based ensemble classifier to identify invasive Phragmites australis from imagery acquired from uncrewed aircraft systems. Results show that the voting-based ensemble classifier performs well in accurately identifying the invasive plant species, particularly when using multispectral imagery with an accuracy of 91%. The study highlights the need for further research on accurately identifying Phragmites australis at low stem densities.

Summary: This study successfully estimated and mapped the aboveground biomass (AGB) of Phragmites australis in the Nan Da Gang Wetland Reserve in China's Hebei Province using a combination of unmanned aerial vehicle (UAV) and Sentinel-2 data. AGB models were built based on UAV data and then matched with the pixel resolution of the Sentinel-2 image, allowing for the creation of an AGB estimation model. The study demonstrates the effectiveness of using UAVs to obtain AGB samples matched with satellite pixels for satellite-based AGB estimation.

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 tested the utility of RGB UAS imagery for mapping Phragmites in two locations in the U.S. The highest overall classification accuracy of 90% was achieved when pairing the UAS imagery with a UAS-derived CHM. The inclusion of RADARSAT-2 HH polarization and commercial satellite stereo retrievals slightly reduced classification accuracy.

Summary: The field experiment in the Yellow River Delta demonstrated that rhizosphere addition of biochar significantly improved the growth and fine root mass of Phragmites australis, while decreasing nitrate nitrogen content and electrical conductivity in the soil. The effects of biochar addition were more pronounced in sites with medium to high salt levels.

Summary: Efforts to reduce greenhouse gas (GHG) emissions are increasingly focusing on paludiculture, the use of rewetted peatlands. Rewetting peatlands can significantly reduce GHG emissions from the soil, with Phragmites australis showing a more pronounced reduction compared to Typha latifolia. This study concludes that Phragmites australis is the most suitable wetland plant species to cultivate after peatland rewetting, due to its greater potential for reducing global warming potential.

Summary: The study found that under copper stress, Phragmites australis showed decreased chlorophyll content, inhibited expression of important photosynthesis proteins, and reduced photosynthesis. However, the levels of ascorbic acid and proline increased, limiting copper migration within the plant. These findings provide insight into the tolerance and repair mechanisms of plants in response to heavy metal pollution.

Summary: Drainage and agricultural use of peatlands turn them from a carbon sink into a carbon source. Rewetting of peatlands can mitigate climate change by reducing CO2 emissions, but the time it takes for this transition is unknown. This study presents 14 consecutive years of methane (CH4) flux measurements following peatland rewetting, showing the importance of an integrative approach to understand CH4 emissions in shallow lakes.

Summary: Massive strandings of seaweed on the eastern coasts of the Yucat ' an peninsula, Mexico have become a major socioecological problem. A citizen science initiative, Big Seaweed Search Mexico (BSS-Mx), was developed to monitor temporal changes in the biomass stranded. The results represent baseline information that should be considered to develop management strategies and marine conservation actions according to each region.

Summary: Riverine macrophytes play crucial ecological roles in river ecosystems, but their growth models have received relatively limited attention compared to other aquatic or terrestrial plants. This systematic review reveals that current models often overlook important factors such as shading and the role of macrophytes in nutrient cycles. Future research should focus on exploring these factors and developing a conceptual framework to guide macrophyte growth modeling. Emphasizing modularity and accessibility is also important for improving efforts to model and manage riverine ecosystems.

Summary: Bryophytes can play a significant role in ecosystem processes and hold potential as bio-indicators for monitoring environmental pollution. This study examined the effects of NO3- pollution on the elemental composition of aquatic and semi-aquatic bryophytes and identified suitable species as bio-indicators. Higher NO3- concentrations were found in spring water from intense farming and urban areas, positively correlated with N content and delta N-15 isotope ratio in bryophytes. Apopellia endiviifolia and Oxyrrhynchium speciosum were highlighted as promising candidates for bio-indication of aquatic NO3- pollution.

Summary: This study investigated the seed production, seed banking, and germination cues of sub-tropical Vallisneria americana. It was found that the seeds of sub-tropical populations were dormant and could only germinate in the presence of organic material, light, or following scarification. Germination rate was enhanced by the presence of low-oxygen organic sediments and ethanol. These findings suggest a germination strategy focused on exploiting openings in existing vegetation following disturbance.

Summary: Constructed wetlands treating runoff from agricultural catchments can reduce nutrient load of water, but they can also be significant sources of greenhouse gases, especially methane. This study assessed methane emission potentials and phosphorus removal efficiency in a 0.45 ha in-stream surface flow constructed wetland, and analyzed the temporal dynamics of methane emissions and phosphorus removal over a nearly 4-year period. The results showed a clear seasonal dynamic in phosphorus removal efficiency and an increasing trend in methane emissions over the years, with the majority of methane fluxes occurring during the warm period. Maintenance of the wetland and regular removal of aboveground vegetation can reduce methane emissions, and regular sediment removal is also necessary due to phosphorus saturation.

Summary: Nutrient availability and light intensity play important roles in the expansion of amphibious clonal plants from terrestrial to aquatic habitats. High nutrient levels and light conditions promote the growth of the apical portions and overall performance of the clones. Maintaining clonal integration can benefit the expansion of the plants by optimizing resource utilization. These findings have implications for predicting community dynamics and vegetation restoration in ecotones like wetlands.
