Summary: This study used a 3D fully coupled modeling system to simulate the final vegetation cover and timescale of salt marshes under different forcing conditions. The simulations showed that sediment concentration, settling velocity, sea level rise, and tidal range each had different impacts on the equilibrium coverage and timescale of marshes.

Summary: Hybrid living shorelines combine engineered structures and natural ecosystems to achieve coastal protection and habitat restoration, with additional benefits such as carbon sequestration. The effectiveness of rock fillets in achieving these goals is uncertain due to a lack of data. Our study examined the impact of rock fillets on mangrove development, bank stabilization, and carbon sequestration. The design of rock fillets significantly affected mangrove structure and coastal protection function, highlighting the need for optimization.

Summary: Salt marshes are at increasing risk of degradation and loss, and the Salt Marsh Rapid Assessment Method (MarshRAM) provides a science-based approach to gather data and guide management strategies. The method assesses salt marsh characteristics, ecological value, disturbance, integrity, and potential for landward migration. MarshRAM data can inform restoration and conservation efforts, and our findings suggest that inundation stress and high-marsh vegetation loss are indicators of vulnerability and degradation.

Summary: Research shows that nature-based shoreline stabilization methods can increase resilience of coastal ecosystems by improving their ability to return to predisturbance states. Living shorelines have been found to experience less damage during hurricanes and provide better storm protection compared to traditional shoreline stabilization alternatives. Environmental and design variables play a role in the resilience of living shorelines, which have been shown to reduce erosion and promote lateral building up of shoreline zones during short-term disturbance events.

Summary: The study utilized pollen data from a deep-sea sedimentary record in the northern South China Sea to explore the historical behavior of coastal wetlands over the past 140,000 years. The research found a close link between sea-level rise and the expansion of coastal salt marshes, indicating a certain resilience of coastal wetlands to future sea-level rise.

Summary: This study investigates the effects of plant invasions on soil microbial communities and functions in salt marshes. It finds that microbial diversity is positively correlated with the duration of invasion, and both bacterial and fungal communities show consistent changes with invasion. The metabolic potential of soil microbes decreases in response to invasion, leading to carbon accumulation in invaded salt marshes. Bacteria and fungi have distinct contributions to microbial community assembly along the invasion gradient.

Summary: Salt marshes provide important ecosystem services to coastal communities, while living shorelines can provide suitable habitat for nekton communities, including juveniles and forage base species. The construction of living shorelines, such as rock sills, does not seem to diminish the habitat quality in the marsh or nearshore waters and may provide enhanced structural shoreline habitat.

Summary: Coastal wetland restoration has been conducted worldwide, and understanding whether it can recover the original biogeochemical functioning is crucial. A study in the Liaohe River Delta, China, found that restored salt marshes had increased soil organic matter and abundance of elements, with soil organic matter explaining a significant portion of variation in element composition. The accumulation of soil organic matter plays a key role in the recovery of soil biogeochemical functioning in salt marshes.

Summary: Livestock grazing generally enhances ecosystem multifunctionality in salt marshes, with a stronger impact in the middle marshes than in the high ones. Despite some indicators decreasing under grazing, activities of soil microbes and nematodes, soil nitrogen pool, nitrogen mineralization, decomposition, and soil respiration all increased.

Summary: This study investigates the influence of Triglochin concinna on the salt marsh plain plant assemblage in terms of nitrogen dynamics. The results show that Triglochin can accumulate nitrogen in its roots and shoots, release nitrogen to neighbors as its litter decomposes, and reduce the biomass of surrounding plants. This suggests that Triglochin can play a role in the restoration of salt marsh vegetation.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
