Summary: An inherent issue in high-throughput sequencing applications is the relative abundance data it provides. In order to overcome this limitation, the authors have proposed a high-throughput absolute quantification (HAQ) method to quantitatively estimate the fungal abundance in Daqu. The results from this study demonstrate that the HAQ method provides different community profiles compared to relative abundance data, and it has been successfully applied to study the fungal ecosystem in Daqu during fermentation.

Summary: An evaluation was conducted on the efficiency of a vertical subsuperficial tidal flow constructed wetland in removing carbonaceous, nitrogenous, and phosphorous matter from urban stream water. The study showed that the optimal flooded time helped in the removal of COD and TN, while longer flooded time was necessary for effective TP removal.

Summary: The study found widespread presence of antibiotic resistance genes (ARGs) in fresh snow, and their dissemination may be exacerbated by air pollution. Snowfall effectively spreads ARGs from point sources to the Earth's surface, highlighting the need for better pollution control measures to reduce the global dissemination risk of antibiotic resistance genes.

Summary: Paddy fields are a significant source of nitrous oxide (N2O), with biotic processes dominating N2O production. Heterotrophic denitrification (HD) is the main process generating N2O, while nitrifier denitrification (ND) also contributes to N2O production. Ammonium content and the ratio of total organic matter to nitrate are important factors affecting the contribution ratios of different N2O production pathways.

Summary: The contribution of agriculture to the sustainable development goals requires climate-smart and profitable farm innovations. Increasing ammonia fertilizer applications result in high agricultural costs, environmental quality deterioration, and global warming, without a significant increase in crop yield. However, a recent study has found that a third microbial ammonia oxidation process called complete ammonia oxidation (comammox) is contributing to significant ammonia fertilizer loss in agricultural soils around the world. This overlooked process has important implications for sustainable development in agroecosystems.

Summary: Significant attention has been given to the response of the soil N cycle to permafrost thaw, but little is known about anaerobic N transformations in thermokarst lakes. In this study, large-scale measurements of anaerobic N transformations in 30 thermokarst lakes in the Tibetan alpine permafrost region were conducted. The results showed higher rates of gross N mineralization, ammonium immobilization, and dissimilatory nitrate reduction in the eastern part of the study area. Denitrification dominated the dissimilatory nitrate reduction processes, and the abundances of denitrification genes were consistent with sediment N transformation rates.

Summary: Since the start of the Anthropocene, northern seasonally frozen peatlands have been warming rapidly, resulting in increased nitrogen mineralization and substantial emissions of nitrous oxide (N2O) during the thawing periods in spring. Heterotrophic bacterial and fungal denitrification were identified as the main sources of N2O in frozen peatland profiles. Thawing significantly stimulates the expression of genes encoding N2O-producing protein complexes, leading to high N2O emissions during the spring thawing period.

Summary: Climate change accelerates the shrinkage of inland lakes globally, leading to increased water salinity and DIC. The study found that increased DIC mitigates the constraints of salinity on microbial primary producers and primary production, enhancing primary productivity in lakes. The findings suggest that inland lakes may support higher primary productivity in future climate change scenarios.
