Effects of periodic drying-wetting on microbial dynamics and activity of nitrite/nitrate-dependent anaerobic methane oxidizers in intertidal wetland sediments

Feiyang Chen et al.

Summary: Tidal-induced shifts of n-DAMO activity and associated contribution to mitigating CH4 in intertidal wetlands were studied. The study found that the wetting-drying events caused by tidal cycling had significant effects on the abundance and activity of n-DAMO microbial communities. The presence of n-DAMO bacteria and archaea and their higher biodiversity under reflooded conditions were also observed. Structural equation modeling and correlation analysis indicated that n-DAMO activity was influenced by microbial abundance, substrate availability, and salt accumulation in sediment. This study provides valuable insights into accurately estimating CH4 emissions from intertidal wetlands under different tidal scenarios.

Emissions of Nitric Oxide from Photochemical and Microbial Processes in Coastal Waters of the Yellow and East China Seas

Jiang-Chen Gong et al.

Summary: This study investigates the contribution and production mechanisms of nitric oxide (NO) in the ocean. High-resolution observations were conducted in the Yellow Sea and the East China Sea, revealing uneven distributions of NO sea-air exchange and analyzing NO production from photolysis and microbial processes. The findings show that NO emissions from coastal waters will increase with reduced terrestrial NO discharge.

Stimulation of ammonia oxidizer and denitrifier abundances by nitrogen loading: Poor predictability for increased soil N2O emission

Yong Zhang et al.

Summary: The study found that nitrogen loading significantly increased the abundance of ammonia oxidizers and denitrifiers in soil, but this did not directly correlate with changes in soil N2O emission. Abiotic factors such as mean annual precipitation, soil pH, soil C:N ratio, and ecosystem type were key in regulating nitrogen-induced changes in soil N2O emission.

Surface Water and Groundwater Interactions in Salt Marshes and Their Impact on Plant Ecology and Coastal Biogeochemistry

Pei Xin et al.

Summary: Salt marshes are important ecosystems that provide essential ecological services, but they have been lost globally due to human activities and climate change. The interactions between tidal water and groundwater in salt marshes affect plant growth and biogeochemical exchange with coastal water. However, there are still significant knowledge gaps regarding the hydrological and ecological links in salt marshes and the challenges they face.

N2O emission dynamics along an intertidal elevation gradient in a subtropical estuary: Importance of N2O consumption

Dengzhou Gao et al.

Summary: Studying N2O production and consumption processes along an intertidal elevation gradient can improve the understanding of N2O dynamics among coastal wetlands. The results showed that N2O emission rates were higher in high tidal zones compared to middle and low tidal zones. Gross N2O production and consumption rates were greater in high and low tidal zones, whereas N2O consumption proportions generally increased from high to low tidal zones. Bacterial denitrification was the dominant pathway, although NH2OH oxidation/fungal denitrification also contributed substantially to N2O production in high tidal flats. Changes in N2O dynamics along the elevation gradient were affected by carbon and nitrogen substrate availabilities as well as the redox environments.

Climate warming, but not Spartina alterniflora invasion, enhances wetland soil HONO and NOx emissions

Dianming Wu et al.

Summary: Climate warming and plant invasion can worsen air pollution by increasing soil nitrogen cycling and emissions of reactive nitrogen gases. Warming increases soil NOy emissions and decreases microbial diversity and abundance, resulting in a more polluted air quality.

Tidal variation and litter decomposition co-affect carbon emissions in estuarine wetlands

Yu Peng et al.

Summary: Estuarine wetlands in the Chongming area were studied to understand carbon emissions and their driving factors. It was found that Scirpus mariqueter and Phragmites australis dominated areas had the highest methane and carbon dioxide emissions. Litter decomposition increased emissions and nutrient release, promoting the abundance of methane-producing archaea and methane-oxidizing bacteria. However, tidal water level negatively correlated with emissions, and the contribution of tidal variations to carbon emissions decreased over time.

Functional Traits Resolve Mechanisms Governing the Assembly and Distribution of Nitrogen-Cycling Microbial Communities in the Global Ocean

Wen Song et al.

Summary: This study uses Tara Oceans shotgun metagenomes to describe the global biogeography of marine N-cycling microbial communities. It finds that marine N-cycling communities exhibit functional redundancy properties and are influenced by depth as a major factor. Taxonomic groups show latitudinal diversity gradients, while functional traits display less variation. Functional traits are determined by environmental factors, while taxonomic groups show more stochasticity.

A strong temperature dependence of soil nitric oxide emission from a temperate forest in Northeast China

Kai Huang et al.

Summary: Nitric oxide (NO) emissions from forest soils play a significant role in atmospheric chemistry and air quality. However, global forest soil NO emission inventories are uncertain due to limited monitoring data, particularly from unmanaged forests. In this study, high-frequency measurements over two years in a mixed forest in Northeast China revealed that the mean annual NO emission was 0.42 +/- 0.04 kg N ha(-1), accounting for 31% of the global forest average. Soil temperature was identified as the primary factor regulating NO emission, explaining 90-92% of the seasonal variation.

Soil Moisture Control of NO Turnover and N2O Release in Nitrogen-Saturated Subtropical Forest Soils

Ronghua Kang et al.

Summary: The acid forest soils in South China receive high levels of atmospheric nitrogen, making them hotspots for gaseous nitrogen emissions. Soil moisture plays a major role in determining the partitioning of gaseous nitrogen loss into nitric oxide and nitrous oxide. This study investigated the gas phase kinetics of nitric oxide and nitrous oxide release during laboratory drying of acidic surface soils from two hydrologically distinct environments. The results showed that potential nitric oxide loss outweighed potential nitrous oxide loss in N-saturated, acid forest soils.

Summary: The study found that soil microbial communities involved in nitrogen cycling are significantly influenced by the composition of overstory trees in temperate forests. Trees associating with different types of fungi have different impacts on the N-cycle potential and activity of soil microbial communities. In addition, there is a linear decrease in volatile reactive nitrogen gas flux with increasing abundance of ectomycorrhizal trees.
