Summary: Floating Treatment Wetland (FTW) is a cost-effective and easy-to-retrofit device for stormwater treatment. The study found that the design configurations of FTW, such as geometry, position, and inlet-outlet, significantly affect the hydrodynamics and treatment efficiency. Circular FTW geometry near the inlet with a center inlet-side outlet configuration achieved the highest removal rate, while far side inlet-side outlet configuration performed the worst due to short-circuiting. The results provide valuable insights for practitioners to improve water quality and ecological improvement goals.

Summary: The study investigated the use of steel slag as a filler in constructed wetlands for treating low-phosphorus contaminated water, observing its effects on phosphorus removal and potential risks of phosphorus release. Results showed increased phosphorus concentrations in effluents of certain wetland components due to the decay of plant tissues, highlighting the importance of cautious application of steel slag in CW systems.

Summary: Efforts to conserve the pond network in Donana National Park are under threat from excessive groundwater extraction, which has resulted from the expansion of farming and tourism in the surrounding areas. This has led to a decline in the water table, causing a reduction in the hydroperiod of the ponds and even their desiccation. It is crucial to establish the link between groundwater abstraction and pond deterioration to address human impacts and protect the unique biodiversity of the pond network.

Summary: The ISFCW system effectively removed nutrients from WWTF effluent during the summer period, with contributions of VSP, BGB, and SFCW to nutrient removal ranging from 3-78%. The key removal processes appeared to be biological and physicochemical pathways, and the integration of VSP, BGB, and SFCW enhanced the purification capacity of the system.

Summary: This study conducted a meta-analysis of eight international FTW studies to investigate the influence of retention pond, catchment, and FTW design characteristics on effluent concentrations. The results showed that pond design features had the most influence on effluent water quality, while the benefits of FTWs were limited to improving the mitigation of phosphorus species and TSS.

Summary: Understanding the ecological niche space (ENS) of gold-spotted pond frogs is crucial for conservation efforts in South Korea. The stable isotope analysis revealed that these frogs have a broader ENS in ecological wetland parks compared to rice paddies, showing diverse feeding behavior. While there is a high probability of ENS overlap with competitive frog species, gold-spotted pond frogs can adapt by consuming alternative food sources less affected by competition.

Summary: This study used bi-temporal airborne lidar data to compare changes in vegetation height near anthropogenic disturbances in the Oil Sands Region of Alberta, Canada. The results showed that up to 50% of wetlands were disturbed by anthropogenic activities, with bogs experiencing increased shrub growth and expansion, while fens and swamps showed varying responses to disturbances. Wetland shapes becoming elongated were associated with a decline in shrub prevalence between the two time periods.

Summary: The study showed that the integration of HRAP and SMP in CW had synergistic effects on water purification. The performance of the hybrid system was significantly better than individual reactors. Extending the hydraulic retention time in the hybrid system improved effluent quality, demonstrating the cost-effectiveness of this wastewater treatment technology.

Summary: The study found that amphibian density and encounter rate decreased with water-source proximity, but increased with pond-side grass height. Additionally, the likelihood of encountering amphibians in tilapia-only ponds was higher than in catfish-only or tilapia and catfish ponds.

Summary: Discharges of warm water from shallow stormwater management ponds during summer months into receiving headwater streams pose a risk to aquatic ecosystems. This research introduces a user-friendly and more accurate machine learning method to predict thermal profiles in stormwater ponds and the pond outlet discharge temperature to the receiving streams. The methods presented in this study can be used to support improved stormwater management pond design guidelines.

Summary: Constructed wetlands in a subtropical monsoon climate area of eastern China were seasonally assessed for six years. The study found that the removal efficiency of pollutants varied significantly among different seasons. By optimizing controllable operating parameters, efficient and sustainable long-term operation of constructed wetlands can be achieved.

Summary: Constructed farm ponds are common landscape features in the midwestern United States, but their efficacy in nutrient removal remains uncertain. This study used high-frequency measurements to analyze the nutrient budgets of a typical farm pond in central Iowa, revealing the impact of in-stream nitrogen processing and transport-vs.-supply-limited nitrogen delivery. The study also showed the importance of wet antecedent conditions on supply limited nitrogen delivery within the watershed.

Summary: A full-scale deep oxidation pond with horizontal subsurface flow constructed wetland was used to investigate nutrient removal and establish a practical prediction model. The study showed that the DOP-HSCWs achieved high removal efficiencies for various pollutants and demonstrated sustained excellent purification of rural polluted river water. The effluent concentration was influenced by influent loadings and seasonal variations. The study also highlighted the microbial composition differences between seasons.

Summary: This study predicted the distribution and richness of aquatic insect species in Swiss running waters under climate change using different modeling approaches, showing a potential decrease in EPT richness of around 10% in the least conservative scenario. Global warming poses a threat to high-elevation species, while lowland and medium-elevation running waters are more vulnerable in terms of species richness. The results also suggest that anthropogenic activities may override natural factors in shaping the future of river biodiversity.

Summary: This study introduces a novel meta-community approach to investigate the relationship between total mercury accumulation in adult caddisfly assemblages and species traits and different habitats. The results suggest that the variation of total mercury concentration among caddisfly species is primarily influenced by larval feeding type, with minor contributions from adult size and larval habitats.

Summary: Large river floodplains are dynamic environments that shape aquatic biodiversity through the interplay of surface flow connections and groundwater inputs. This study shows that the relative importance of these inputs varies depending on the morphology of the floodplain channels, and that both lateral surface water connections and vertical groundwater connectivity contribute to species turnover and maintenance of biodiversity in floodplain habitats.

Summary: In large river floodplains, the availability of trophic resources to young-of-the-year fishes can vary due to seasonal environmental change and habitat diversity. This study investigated the composition of planktonic assemblages and the diet of three fish species from four floodplain sites, and found that the diet of the young fishes was mainly based on zooplankton when their density was sufficient, but switched to phytoplankton when the density was insufficient. The study also revealed that the diet overlaps between species differed significantly between sites, highlighting the importance of examining the diet of juvenile fishes and environmental variables in floodplains.
