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: This study investigates the efficiency of nutrient removal in a constructed wetland used to treat urban runoff. The findings show low removal efficiency for dissolved inorganic nutrient (DIN), but high efflux of dissolved inorganic phosphate (DIP). Due to short water residency and increased flow volume, the surface area of the wetland needs to be increased to cope with the current daily inputs.

Summary: The effectiveness of constructed floating wetlands (CFWs) for wastewater treatment in cold climates is largely unknown. A pilot-scale CFW system was implemented in a municipal waste stabilization pond in Alberta, Canada. The study found that increasing the CFW area and adding underneath aeration promoted plant uptake of elements, leading to significant reduction of pollutants in the water. The results suggest that CFWs are a viable ecotechnology for municipal wastewater treatment, but larger and aerated systems are recommended for maximum remediation.

Summary: To meet the demand of a growing population, agriculture intensifies and leads to increased use of fertilizers and pesticides, which can disrupt water quality and impact aquatic life. This study evaluates the efficiency of an agricultural retention pond in reducing the supply of nutrients, pesticides, and suspended solids to a tributary of Lake St. Pierre. The study finds that the removal of pesticides varied, while the removal of suspended solids, phosphorus, and nitrogen was relatively high. However, the retention pond was not consistently effective in removing toxicity.

Summary: This study investigated the dynamics of microplastics (MPs) in a newly established surface flow constructed wetland (CW) that receives 1.4 million liters per day of secondary treated wastewater. The study found that most MPs were synthetic fibers and fragments in the size range of 100-1000 micrometers. The CW effectively retained MPs, but the accumulation of MPs in sediments and substrate needs to be considered.

Summary: The A-01 wetland treatment system was designed to remove metals primarily copper from effluent, with consistent removal of Cu averaging about 80% over 20 years of operation. Most divalent metals were rapidly removed from water and held in sediments shortly after entering the treatment wetland. Highest concentrations of Cu, Pb, and Zn were found in sediment from the first cell in each pair, indicating that most of these metals in the effluent were quickly bound to the sediment.

Summary: This study evaluated the technical feasibility of a multilayer detention roof, called a purple roof, in managing urban stormwater. The purple roof outperformed other roof systems by delaying the start times of runoff, reducing runoff volume, and taking longer to discharge stormwater. The study demonstrates that the purple roof technology is effective in slowing the release and reducing the volume of stormwater during different-sized rainfall events.

Summary: This study used satellite imagery and a methane emission model to estimate the surface water extent and diffusive methane fluxes in wetlands, showing that wetlands smaller than 1 hectare were responsible for the majority of emissions. Considering the dynamic inundation of forested wetlands resulted in 49%-62% lower emission totals compared to models using a single estimate for each wetland's size.

Summary: The presence of protected snails in restored stream communities can disrupt vulnerable prey populations and have long-term negative effects on predators. Additionally, mayflies appeared less on surfaces with high snail densities, potentially due to altered resource use. These biotic interactions may form a barrier to successful biotic restoration by preventing colonization of desired vulnerable prey.

Summary: Methane emissions from small freshwater ecosystems are a major uncertainty in the global methane budget. The study found that inundation extent and duration, as well as the direction of water level change, are major drivers of methane emissions in seasonally inundated forested wetlands. Modeling the hydrologic regime of these wetlands can lead to more accurate estimation of methane emissions.

Summary: Halting the global decline of freshwater mussels requires a better understanding of the shortcomings in current restoration methods and the development of new approaches. Evaluations of restoration efforts are limited and biased temporally and geographically, with a focus on mussel-diverse regions in North America and Europe. Efforts mainly involve population support such as relocation, translocation, and captive breeding, and future restoration approaches emphasize planning and prioritization.

Summary: The decline in phosphorus and the increase in nitrogen to phosphorus ratios have resulted in re-oligotrophication in rivers and estuaries of high-income countries, while widespread eutrophication occurs in low-income countries. The biotic response and ecological effects of these changes, as well as the N:P imbalance, need further investigation. The regime shift from phytoplankton to macrophyte dominance, documented in shallow lakes, is less observed in rivers and estuaries.

Summary: Wetland soils serve as a vital carbon sink globally and play a crucial role in carbon management and accounting. However, the lack of reference information and incomplete understanding of wetland variability hinder the accurate assessment of carbon storage potential. This study aimed to quantify the variability in wetland soil organic carbon (SOC) stocks on a depressional landscape and investigate the role of hydrology and relative topography. The results indicate high variability within and among wetlands with similar characteristics, suggesting the need to explicitly address uncertainties when inferring ecosystem processes. Hydrology and relative topography were found to be important factors in explaining SOC stock variability, emphasizing the importance of considering these factors in large-scale analyses and wetland restoration efforts.
