Summary: The study investigates the interaction between forest-derived dissolved organic matter (DOM) and natural iron-bearing minerals in forest subsoils. The results show that natural iron minerals have a higher capacity for sorbing leached DOM compared to biochar-derived DOM. Oxygen/nitrogen-rich polycyclic aromatic compounds and carboxylic-containing compounds in leached DOM preferentially sorb to iron minerals, while unsaturated and oxidized phenolic compounds in biochar-derived DOM have a stronger affinity for iron minerals. The composition of DOM profoundly shapes SOM formation and persistence in forest subsoils.

Summary: Plants, soils, and microorganisms have essential roles in maintaining stable terrestrial stoichiometry, but the effects of warming on their stoichiometric relationships are not well understood. This meta-analysis of 600 case studies found that warming had inconsistent effects on the stoichiometric ratios of plants, soils, and microorganisms, with noticeable effects on plant N:P ratios. However, the stoichiometric correlations among all three components remained constant across different warming scenarios. These findings highlight the complexity of the warming effects on C:N:P stoichiometry and the need for simultaneous measurements in future studies.

Summary: Climate change has significant impacts on marine fish and fisheries in the Yellow Sea. This study predicts the temperature and distribution of nine representative fish species using dynamic bioclimate envelop models. The results show that different types of fish have different migration patterns and relative abundance under climate change.

Summary: The effective communication of flood hazard and risk is crucial in reducing the detrimental impacts of flooding events. Traditional flood maps are often difficult to understand, leading to the use of color maps for better communication. However, these hazard indexes have inherent limitations. Therefore, the use of a physics-based and data-consistent risk index, such as the loss probability (LP) map, is proposed for a more accurate estimation and communication of flood risk.

Summary: Horizontal gene transfer (HGT) in activated sludge (AS) bacteria poses a potential risk in the spread of antimicrobial resistance genes (ARGs) and virulence factor genes (VFGs). Alphaproteobacteria and Gammaproteobacteria are the primary classes involved in gene transfer. Mobile genetic elements play a significant role in the transfer of ARGs and VFGs in AS bacteria.

Summary: This study analyzes the spatiotemporal variations of transition probabilities of wet and dry days in the Susurluk Basin in northwestern Turkiye and finds that the number of dry days will increase in the future, increasing the risk of drought. The study also points out that the western part of the basin, where human activities are intense, has a higher number of dry days, especially in summer.

Summary: Reservoir construction has a significant impact on the natural transport of riverine water and sediment, as well as trace metals and pollutants. This study found that the migration and accumulation of trace metals were influenced by the adsorption of fine-grained sediments and oxidative processes. In the estuary, the trace metals were scavenged by reservoir-sourced fine particles and affected by the reducing environment.

Summary: This study successfully improved the adsorption capacity of soil tetracycline and alleviated its negative effects by modifying corn stover biochar with phosphate. The type of phosphate and pyrolysis temperature played important roles in the performance of the modified biochar, and K3PO4-800 showed the best adsorption capacity.

Summary: Soil microbial communities play a vital role in plant nutrition and stress tolerance, especially in sites contaminated by trace metals. However, there is limited knowledge about the factors affecting the richness and composition of these communities in contaminated sites. This study found that the site and plant species identity significantly influenced the composition of bacterial and fungal communities in the rhizosphere, indicating the importance of considering these factors in assisted revegetation efforts at contaminated sites.

Summary: This study investigates the effects of heat exposure on oxidative and immune indices in Largemouth Bass (LMB) and reveals that chronic heat exposure induces oxidative stress, impairs immune function, and increases susceptibility to bacterial infection. RNA sequencing analysis further reveals the gene expression changes associated with chronic heat exposure and bacterial infection, shedding light on the underlying mechanisms.

Summary: This study investigates the nonlinearity of root respiration responses to the interactions of nitrogen enrichment and extreme water change. The experiment was conducted in an alpine meadow for 6 years, coinciding with extreme precipitations. Results show that root respiration exhibited divergent responses to nitrogen addition under different water conditions. Root biomass and traits were found to be critical mechanisms affecting root respiration response, with their relative importance changing with water condition.
