Summary: The study found that a salinity of 7% and 10% can promote the organic carbon release from reed biomass. The highest nitrate removal was observed at a salinity of 7%, and this removal rate increased from 54.06% to 74.37% after adding reed biomass. Additionally, the lowest nitrous oxide emission flux was also observed at this salinity, with a rate of 0.23 mg/(m2 h). Microbiological analysis showed that salinity had an impact on the microbial community, with an increase in the relative abundance of Chloroflexi and Actinobacteria and a decrease in Proteobacteria. The main functional genera of denitrification also changed with increasing salinity.

Summary: Root traits play a significant role in regulating plant growth and ecosystem functioning. This study found that the root traits of exotic Spartina alterniflora were more sensitive to changing soil nutrient availability compared to native Phragmites australis. Climate and soil nutrient availability had different effects on the productivity of the two species, with root traits playing a species-specific role in mediating these effects.

Summary: This study investigated the water-use strategies of Phragmites australis in the tidal marsh of the Yellow River Delta and found that its water-use efficiency varies with seasons and is influenced by plant traits and soil factors. The study suggests that precipitation is the main water source in coastal wetlands, and supplementing fresh water during the drought season is recommended for the conservation of these plants.

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: Sea level rise in New England is accelerating faster than the global average, posing a threat to salt marshes. This study examines the use of runnels as a climate adaptation strategy to enhance drainage in drowning marshes and finds positive impacts on soil properties and vegetation composition, as well as an increase in carbon dioxide uptake.

Summary: A global concern for coastal ecosystems is the predicted rise in sea-level for which salt marshes must keep pace. Variables that control this elevation change need to be identified to predict the adaptability of marshes to future sea-level rise. Grazing by livestock can significantly reduce the annual rates of elevation gain and affect the future adaptability of salt marshes to grow vertically for rising sea levels. Trampling by grazing cattle, along with other factors like precipitation deficit and extreme drought, can lead to biocompaction and reduce the total elevation change.

Summary: The study estimated the parameters of the photosynthesis-irradiance relationship in a sedge-grass marsh in the Czech Republic, Europe, finding that different plant species have different parameters in this relationship. Sunlight-saturated photosynthesis rates vary among different plant species and growth periods, and species composition plays a crucial role in influencing the photosynthetic parameters of the big-leaf representing the marsh in different seasons.

Summary: Salt marshes play a key role in attenuating wave energy and promoting sedimentation necessary to potentially adapt to sea level rise. The soil surface elevation in the marsh region varies spatially and temporally as a function of marsh topography, inundation frequency, and distance to the salt marsh edge. The sedimentation rate reduces linearly shoreward and is highest around the mean high-water level, moving towards the edge of the salt marsh with marsh extension and increasing soil surface elevation.

Summary: Salt marsh ecosystems, located at the terrestrial-aquatic interface, are often overlooked in process-based models. In this study, we investigated the role of leaf nutrients on canopy photosynthesis (F-A) in a temperate salt marsh using multiyear data and remote sensing techniques. We found that F-A was positively related to canopy-level nitrogen (N) at the ecosystem scale and in areas dominated by Spartina cynosuroides. However, this relationship was not observed in areas dominated by short S. alterniflora. F-A showed positive relationships with canopy-level phosphorus (P), potassium (K), and sodium (Na), but a negative relationship with iron (Fe). The findings suggest that spatial variability in salt marsh vegetation and the application of canopy surface hyperspectral remote sensing have promising potential for understanding how these ecosystems respond to global environmental change.

Summary: In this study, the impact of crab bioturbation on the redox geochemistry of iron, phosphate, and sulfide in coastal wetlands was investigated. The results showed that crab burrowing activities created deep depths for redox reactions and facilitated the coupling of Fe and S, leading to spatial variability in soil geochemistry. These findings highlight the importance of crab burrows in mediating the cycling of key elements in wetland ecosystems.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

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.

Summary: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
