Summary: Bisphenol S (BPS) shows different dissipation rates in soils with different pH values. Mineralization and bound residues are the main contributing factors to the dissipation of BPS. BPS is persistent in acidic soil and may pose a threat to plants in acidic soil. Soil microorganisms and organic matter content play key roles in BPS degradation. Two transformed products were identified in soils.

Summary: This study investigated the fate of Cd in different soil conditions treated with wheat straw biochar and its driving mechanisms. The addition of biochar facilitated Cd immobilization and reduced Cd uptake by green vegetables in various soils. However, in acidic soil, the release of exchangeable aluminum from biochar led to increased leaching of Cd. The remediation performance of biochar for Cd-contaminated soils is conditional and more effective in neutral and saline-alkali soils.

Summary: This study investigated the distribution characteristics and hazard levels of heavy metals in karst soil in a mountainous county in China. The results showed that the levels of heavy metals in karst areas exceeded the background values, while non-karst areas did not. The presence of heavy metals in karst areas was mainly influenced by carbonate rock parent material. The potential ecological risk in karst areas, especially for Cd, was higher compared to non-karst areas.

Summary: The study investigated the effects of rice straw and potential nitrogen fixing Bacillus subtilis on carbohydrate- and nitrogen mineralization in long-term rice paddy soil through anaerobic incubation. Results showed that decomposed carbohydrate ranged from 83-447 mg kg(-1) soil, with extracted carbohydrate not affected by rice straw application but significantly decreased with Bacillus sp. or rice straw-Bacillus sp. inoculation. Nitrogen mineralization increased with Bacillus sp. inoculation, while rice straw and combine treatments resulted in more nitrogen immobilization. Inoculation of Bacillus subtilis is recommended to enhance soil fertility and reduce nitrogen immobilization, with further research within rice plants needed to confirm these findings.

Summary: Karst forests have higher soil organic carbon content and microbial resource limitations are mainly co-limited by carbon and phosphorus, while non-karst forests are mainly phosphorus-limited. Microbial biomass is higher in finer aggregates, likely due to increased surface area for microbial carbon accumulation.

Summary: This study revealed that incorporating organic materials in paddy soils can significantly increase total nitrogen content and enhance microbial involvement in nitrogen accumulation by activating N cycling genes. However, compared to rice straw, the addition of manure, although increasing biomass N in soil, showed a weaker relative microbial contribution to nitrogen accumulation.

Summary: This study evaluated the surface charge (SC) dynamics of rice straw-derived phytoliths and paddy soils to characterize their possible contribution to soil SC properties. The results indicated that phytoliths, together with other soil constituents, can regulate the SC of paddy soils to some extent. The annual recycling of rice straw to paddy soils, particularly after burning, can contribute to the negative SC system, affecting soil cation exchange capacity and transport of solutes.

Summary: The pore characteristics of biochar are affected by the feedstocks and pyrolysis temperature, resulting in varying effects on soil pore properties. Biochar addition alters soil pore size distribution, with different types of biochar impacting soil properties differently. The meso- and micropores in biochars play a crucial role in affecting soil response, with a pyrolysis temperature around 450 degrees Celsius being optimal for producing porous biochar with larger porosity.

Summary: In this study, the effects of straw carbonization returning on sea rice yield and DEHP degradation were investigated. It was found that straw carbonization returning significantly improved soil nutrients and reduced salt stress, leading to an increase in sea rice yield. DEHP degradation efficiency was enhanced, mainly attributed to factors such as high pH value, high soil organic matter, and enriched potential DEHP degraders. The results provide important insights into sea rice yield improvement and DEHP degradation mechanisms in coastal paddy soil through straw carbonization returning.

Summary: The study shows that land-use intensification leads to increased soil erosion, impacting ecosystem properties through changes in species compositional and structural diversity. High species diversity and tree height diversity can reduce soil erosion by promoting root length density, with tree height diversity playing a more important role in mediating the indirect effects of land-use intensity (LUI) on soil erosion.

Summary: The study found that land-use intensity indirectly affects soil water conservation primarily through plant functional traits and ecosystem properties. Tree height functional divergence plays a crucial mediating role in the impact of LUI on SWC and SWR. Maintaining functional diversity of tree height in tropical land use is important for mitigating the increased intensity of seasonal drought predicted under climate change.

Summary: The study found that the ecosystem carbon use efficiency (CUE) in the Qinghai-Tibet Plateau may decrease in the future, with a more significant decrease trend as radiation forcing increases. Temperature is the primary climate factor affecting CUE, mainly through its impact on GPP and NPP to produce indirect effects, with a higher comprehensive effect on CUE than precipitation and CO2 on an annual scale.

Summary: This study investigated the variation in leaf delta C-13 of plants on the Loess Plateau and its relationship with environmental factors. The results showed consistent responses of leaf delta C-13 to climate variations among different life forms, families, and species categories of C-3 plants. Climate, soil, species category, and leaf economic spectrum traits collectively explained a significant portion of the variation in leaf delta C-13. The findings contribute to our understanding of plant adaptation strategies in arid conditions and provide scientific support for ecological management in vegetation restoration areas.

Summary: Aboveground carbon storage in forests is influenced by both structural and compositional diversity of plant communities. This study analyzed data from tropical forest plots in Hainan Island, China, and found that structural diversity had a greater impact on aboveground carbon in the overstory stratum compared to compositional diversity. The relationship between diversity and carbon was slightly affected by soil nutrients but strongly influenced by altitude. Altitude indirectly affected overstory tree height and diameter diversity through species diversity, ultimately impacting aboveground carbon storage.

Summary: The hydrologic-related ecosystem services in upstream ecological conservation zones play an important role in regulating water scarcity and conflicts downstream. However, the combined effects of socioeconomic, land use, and climate factors on these services have not been well analyzed, leading to a lack of understanding about their spatial heterogeneity and drivers. In this study, the InVEST model and multivariate analysis were used to assess the interactions of these factors on hydrologic-related ecosystem services in the Beijing Ecological Conservation Development Zone. The results show significant temporal and spatial heterogeneity in water yield and purification services, with land use having the largest impact followed by climate and socioeconomic factors.

Summary: This study proposed a hybrid model (DSP) that combines the advantages of discrete wavelet transform (DWT), support vector regression (SVR), and Prophet to forecast rainfall data. The DSP model provides excellent prediction, with RMSE, MAE, and R-2 values of 6.17, 3.3, and 0.75, respectively. It yields higher prediction accuracy than the three baseline models considered and demonstrates good results when applied to rainfall data from various climate types.
