Summary: Dairy cattle in the US consume byproduct (BP) feeds to produce milk, with 33.5% of lactating cows and 35.7% of milk production in 2019 using BP feeds. These feeds supply a significant portion of essential nutrients for milk production while contributing to lower non-CO2 greenhouse gas emissions compared to alternative disposal methods like landfilling and composting.

Summary: This study found that under anoxic conditions, the consumption of N2O can drive the oxidation of CH4, mainly mediated by methanotrophs in the microbial community. The research reveals the potential mechanisms of N2O-driven CH4 oxidation and highlights the significant role of methanotrophs in carbon and nitrogen cycles.

Summary: This study investigated the abundance, community structure, and co-occurrence network of nosZ I and nosZ II carrying microorganisms in a subtropical coastal wetland. The results showed that nosZ I and nosZ II carrying microorganisms differed in taxonomic identities and were positively associated with salinity, total carbon, and total nitrogen. The study also found that nosZ I and nosZ II likely shared similar ecological niches based on the co-occurrence analysis.

Summary: Denitrification is an important process mediated by microorganisms that can be influenced by the presence of copper. This study found that adding trace amounts of copper enhanced the reduction rate of nitrous oxide (N2O) to nitrogen gas (N2) in wetland soils and stream sediments. A kinetic model showed that the presence of copper significantly increased the conversion of N2O to N2. The study also suggested that in some cases, the overall denitrification process is driven by abiotic reduction of nitrite (NO2-). These findings highlight the significance of copper in controlling denitrification in natural aquatic systems.

Summary: This study evaluates the use of constructed wetland-microbial fuel cells (CW-MFC) as a sustainable solution for reducing greenhouse gas (GHG) emissions. The results show that carbon fiber felt (CFF) exhibits the lowest methane and nitrous oxide emissions among the selected cathode materials. Adjusting the influent pH from acidic to alkaline also reduces GHG emissions. However, the addition of nickel inhibits GHG emissions but decreases electricity generation. Additionally, a low carbon-to-nitrogen ratio reduces methane emissions, while a high ratio effectively inhibits nitrous oxide emissions.

Summary: Research shows that non-native plant invasion significantly affects greenhouse gas emissions, especially in wetland and grassland ecosystems. Plant invasion increases methane and nitrous oxide emissions, but does not affect nitrous oxide emissions in forests and wetlands. Soil organic carbon, mean annual air temperature, and nitrogenous deposition are key factors influencing wetland methane emissions, while terrestrial methane uptake is influenced by mean annual precipitation, soil NH4+, and soil moisture.

Summary: Coastal wetland restoration is a significant activity for achieving greenhouse gas reduction targets, improving water quality, and reaching sustainable development goals. This study in subtropical Queensland, Australia, measured carbon abatement and nitrogen removal potential in restored coastal wetlands. The results showed that tree growth, soil accumulation, and reduced fertilization led to positive carbon abatement, even considering increased methane emissions and enhanced denitrification levels.

Summary: Through the use of double tracer technique and metagenomic sequencing, we found that the production of N2O in plateau wetlands is promoted by nitrifier denitrification, with the key functional genes belonging to comammox bacteria Nitrospira nitrificans. The comammox bacterial species N. nitrificans and ammonia oxidizing bacterial species Nitrosomonas europaea cooperate to produce N2O in plateau wetland sediments. Environmental factors such as elevation and total organic matter influence the cooperation pattern via N. nitrificans, thus affecting N2O production activity in plateau wetland sediments.

Summary: Thawing permafrost due to warming climate combined with severe fires results in the release of carbon and nitrogen, with carbon emissions being well-documented but the fate of nitrogen remaining unclear. This study examined denitrification and N2O production in boreal soils, lakes, and streams and found that riparian soils and stream sediments had the highest potential rates of denitrification. Deep permafrost soils had little denitrification, and time since fire had no effect on denitrification potential in upland soils. The study suggests that widespread N loss to denitrification in boreal forests could constrain the capacity for N-limited primary producers to maintain soil carbon stocks following permafrost thaw.

Summary: The health of China's coastal wetlands is crucial for global bird biodiversity. However, land reclamation, invasive species, and over-harvesting have altered the landscape, affecting bird diversity. This study focuses on the impact of long-term habitat changes on wintering waterbirds in the Tiaozini wetland. It reveals that natural habitats decreased while human-modified habitats increased, leading to changes in species number and population size of different waterbird guilds.

Summary: Constructed wetlands (CWs) with biochar addition showed enhanced removal rates for NH4+-N, total nitrogen, and chemical oxygen demand, while reducing N2O emissions. Nitrous oxide (N2O) emission was mainly contributed by nitrification, denitrification, and simultaneous nitrification and denitrification processes. Adding biochar resulted in significant reduction rates for these processes. The relative abundance of nitrogen-transforming microbes increased after biochar addition, promoting nitrogen removal and reducing N2O emissions. Functional gene copy number and enzyme activity responsible for nitrogen conversion were increased with biochar addition, facilitating efficient NH4+-N oxidation and nitrite elimination, thus reducing N2O emissions.

Summary: Riverine nitrogen loss is an important factor in the global nitrogen budget, but research on nitrogen loss from large turbid rivers is limited. This study focused on nitrogen loss in the Yellow River and found that nitrogen fluxes varied significantly along the river, with suspended sediment concentrations playing a key role in influencing nitrogen loss, particularly in the middle reaches. Further research is needed to better understand the impact of suspended sediment on riverine nitrogen cycling.

Summary: A mechanistic model was developed to assess the removal efficiency of pollutants in a wetland system, particularly in oil sands process-affected water (OSPW). The model simulated wetland mechanisms of chemical removal and showed that sustained wetland treatment is feasible. It is a helpful tool to evaluate the feasibility of treatment systems and to assess trade-offs in wetland design and operation.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
