Summary: This study examined the removal performance of organics and nutrients in intensified constructed wetlands, specifically tidal flow-based microbial fuel cell (MFC) and tidal flow wetlands receiving municipal wastewater. The results showed high removal rates for ammonia nitrogen, total nitrogen, phosphorus, chemical oxygen demand, and biochemical oxygen demand under different flood periods and media variations, with TN removal reaching the highest percentage under 24-h flood periods. Tidal flow-based MFC wetlands outperformed tidal flow wetlands in TN removal due to supplementary electron production through fuel cell-based organics degradation kinetics.

Summary: Recent advances in the integrated bioelectrochemical-constructed wetland systems (BES-CWs) for antibiotics removal have shown promise, providing a competitive and environmentally friendly alternative to physicochemical methods. Understanding the reaction features, operation manners, economic and ecological benefits of BES-CWs is crucial for further technological development. However, successful application of BES-CWs to antibiotics-containing wastewater remediation requires a thorough evaluation of its performance, mechanism, typical attributes, and a comprehensive potential assessment in terms of environmental and economic analysis.

Summary: There is concern that the use and misuse of antibiotics can lead to an increase in antibiotic resistant genes (ARGs) in wastewater. Conventional wastewater treatment plants can release ARGs and antibiotic resistant bacteria (ARB) into natural water bodies. Constructed wetlands (CWs) offer a low-cost solution for wastewater treatment and have the potential to remove nutrients, pathogens, and ARB/ARGs.

Summary: Constructed wetlands (CWs) are engineered systems that utilize natural processes for wastewater treatment. CWs take advantage of processes found in natural wetlands, but operate in a more controlled environment. They can be classified based on the presence/absence of wastewater on the wetland surface, and the direction of subsurface flow. Hybrid CWs combine different types of CW technologies. The use of CWs for wastewater treatment gained popularity in the 1990s and early 2000s due to stricter regulations and the application of CWs in circular economy concepts.

Summary: The diversity of both microorganisms and viruses in activated sludge of wastewater treatment plants plays a crucial role in controlling microbial dynamics and metabolisms. This study reveals the presence of unknown viral genera in activated sludge, indicating an unexplored reservoir for new viruses and viral diversity. The study also shows that viruses can enhance the performance of activated sludge by encoding auxiliary metabolic genes (AMGs) involved in biodegradation, but can also facilitate the spread of antibiotic resistance genes (ARGs) among microorganisms. Overall, this study highlights the mixed blessing of viruses in wastewater treatment plants and their impact on biochemical processes.

Summary: Comparative studies on insects have shown that larger moth species tend to live longer in tropical communities, and females have slightly shorter lifespans than males. The average adult lifespans and lifespan relationships in tropical geometrid moths are highly similar to those in their temperate region relatives. This suggests that intrinsic physiological factors dominate over extrinsic ecological factors in determining moth longevities.

Summary: The study examined the effects of different restoration approaches, past land use, and other factors on the richness and composition of vascular plants, bryophytes, and lichens in middle-aged forests. The results showed that natural regeneration promoted biodiversity the most, but plantations also supported the recovery of biodiversity on abandoned agricultural land. Therefore, both restoration approaches are recommended on a regional scale.

Summary: This study focused on the activity patterns of the predatory asp fish population in a natural lake-river ecosystem. It found that the fish had higher activity levels during the warmer feeding periods of the year and exhibited large annual river movements. Factors such as light, habitat, and water discharge influenced the fish's activity. Understanding these high-activity periods can aid in the development of fishing regulations and highlight the importance of continuous river systems for fish migration.

Summary: This study evaluated the impact of increased silver nanoparticles (AgNPs) and ionic silver on the abundance and removal efficiency of antibiotic resistance genes (ARGs) in a hybrid constructed wetland system. The results showed that higher concentrations of AgNPs significantly affected the abundance and removal efficiency of ARGs, resulting in increased discharge of these genes into the environment. The presence of AgNPs also promoted horizontal gene transfer and increased the levels of plasmid and integron-integrase genes. Further investigation is needed to understand the effects of AgNPs on mobile genetic elements and pathogens in constructed wetlands.

Summary: This study investigates the effectiveness of dispersant use in the Baltic Sea, focusing on oil degradation rates and bacterial community structures. Results show that coastal seawater from the Gulf of Bothnia and Gulf of Finland have the highest oil degradation gene abundances and removal rates, while seawater from the Norwegian Sea have the lowest. Dispersant usage has apparent effects on bacterial communities, but its impact on biodegradation rate remains unclear due to uncertainties in chemical analysis and oil concentration variations.

Summary: Nutrient-rich northern peatlands, once drained for enhancing forest productivity, result in peatland soils becoming methane (CH4) sinks and nitrous oxide (N2O) sources. In addition to soil, tree stems can also emit CH4 and N2O. This study investigates the winter-time dynamics of CH4 and N2O fluxes in a drained peatland forest, considering both soil and stem emissions. The results show that tree stems are a net source of CH4 and N2O during winter, and their emissions can offset the CH4 sink and contribute to forest floor N2O emissions.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
