Summary: The unique spatial niches created by biochar form a dynamic biogeochemical soil zone known as the charosphere. This zone has different properties from regular soil or biochar, and can act as a hotspot for microbial activity. The effects of charosphere on soil processes and microbial communities are still unclear, but the study showed that different types of biochar can have varying impacts on bacterial diversity and composition. The spatial distribution of functional genes and genera within the charosphere gradient highlights the importance of heterogeneity in understanding how biochar can reduce nitrogen losses in agroecosystems.

Summary: The extensive use of organic chemicals has led to the distribution of hydrocarbon contaminants in many ecosystems worldwide. Bacteria and archaea play a dominant role in transforming these contaminants into methane through a syntrophic process. The resulting methane is then oxidized by anaerobic bacteria and archaea in the presence of electron acceptors, contributing to the reduction of methane emissions and climate change mitigation. However, the specific pathways and syntrophic partners involved in this process are still poorly understood.

Summary: Long-term free air carbon dioxide enrichment experiments on rice plants show that plant-available phosphorus declines in paddy soils as atmospheric CO2 increases. The decline in phosphorus concentration is attributed to the production of soil organic phosphorus that is not readily available to plants, as well as increased loss through crop harvest. These findings suggest that future CO2 scenarios may lead to reduced rice yields, particularly in low-income countries, unless additional phosphorus fertilizers are applied.

Summary: The metabolism and bioavailability of arsenosugars in edible seaweeds are influenced by gut microbiota. It was found that mice with disrupted gut microbiota excreted significantly higher levels of total arsenic in urine and lower levels in feces after consuming nori compared to normal mice. Arsenic speciation analysis revealed that phosphate arsenosugars in nori were mostly converted to arsenobetaine, while sulfonate arsenosugar in kelp remained intact in feces.

Summary: Surveillance of antibiotic resistance genes (ARGs) in environmental sectors is increasingly conducted to complement studies in human and animal sectors. However, comparing and synthesizing results from different studies using different test methods and bioinformatic analysis approaches pose substantial challenges. This article suggests a universal unit (ARG copy per cell) for reporting biological measurements of ARGs in order to improve comparability. By comparing commonly used quantification units, this study proposes a step towards standardization.

Summary: Phagotrophic protist communities in long-term Cu-contaminated soils have important impacts on Cu-resistant bacterial populations. Certain communities, such as Cercozoa and Amoebozoa, increase the relative abundance of Cu-resistant bacteria, while the relative abundance of Ciliophora decreases. Phagotrophs positively influence the relative abundance of Cu-resistant and -sensitive ecological clusters, contributing to the abundance of the Cu resistance gene (copA).

Summary: Rapid urbanization leads to increased emission of tire wear particles (TWPs) and the contamination of a transformation product derived from tire antioxidant. The formation mechanisms of the transformation product, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q), during the aging of TWPs in soils are poorly understood. This study reveals that biodegradation is the predominant fate of 6PPD-Q in soils, while anaerobic flooded conditions promote its formation, resulting in higher accumulation of 6PPD-Q in flooded soils compared to wet soils after 60 days of aging.

Summary: Cooperative interactions between free-living and biofilm-forming bacteria are found to drive spatial segregation and enable species coexistence in a microfluidic chip environment, promoting their respective dominance in segregated microhabitats. This active spatial segregation is induced by cooperative interactions, improving the fitness of both biofilm and planktonic populations. The study also shows that free-living Arthrobacter induces surface colonization and receives benefits from public goods secreted by biofilm-forming strains.

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.
