Summary: This study investigates the potential role of soil seed banks in different habitats in Europe and finds that high seed bank diversity and compositional similarity with the herb layer may act as a functional buffer against the impact of global environmental changes on plant communities. However, climate warming could threaten this capacity. Dormant life-history stages can be important sources of diversity in changing environments, but their ability to buffer change may only be temporary.

Summary: This study investigated the plant species-specific microbial communities as mediators of soil legacies, finding that soil legacy effects on decomposition and soil decomposer community composition were most evident shortly after the start of the feedback phase, but disappeared after the establishment of a new plant community. Soil conditioning time and years since disturbance consistently affected soil functions, with no strong effects observed from plant functional group and growth strategy. Recovery time, rather than soil legacy effects, was identified as the most important factor driving soil functions after disturbance.

Summary: This study investigated protist diversity and its driving factors in grassland soils on the Tibetan Plateau. The results showed that soil protist diversity significantly decreased along the gradient of meadow, steppe, and desert. Soil protist diversity was positively correlated with precipitation, plant biomass, and soil nutrients, with precipitation playing a more important role in driving soil protist diversity. The community structure of soil protists gradually shifted along the gradient and was more influenced by precipitation than by plant and soil factors.

Summary: Studying plant-soil feedback (PSF) is important for understanding plant community dynamics. This study examined the temporal variation in PSF at different stages of grassland community succession and identified the influencing factors. The results showed species-specific variation in the PSF pattern, with negative and neutral feedback observed in early- and mid-species, respectively, and positive feedback in late-species. The shoot biomass of early-species was positively correlated with soil nutrients and enzyme activity, while the shoot biomass of late-species was negatively correlated with soil nutrients and enzyme activity in early-species soil. These findings highlight the importance of PSF in plant community succession.

Summary: This study examined the effects of natural restoration on the soil microbial community in a sodic-saline grassland in China. The results showed that natural restoration significantly improved the salinization of the grassland and altered the microbial community structure. However, the effects on bacterial and fungal abundance and diversity were different. Bacterial diversity did not change significantly, while fungal diversity increased in the topsoil. Model-selection analysis further confirmed that the changes in soil microbial structure were related to the adaptation of bacteria to improved soil salinity and fungi to improved soil fertility.

Summary: This study evaluated meta-analyses on the effects of biochar application on soil N2O emissions and proposed a grand mean response ratio (RR) to estimate the overall effect and factors influencing the effects. The results showed that biochar application significantly reduced soil N2O emissions, with the magnitude of reduction ranging from -10.5% to -54.8%. The impacts increased with experimental duration till one and half years and were influenced by biochar application rate and C:N ratio. Meta-analysis provides a more comprehensive estimation, but the inconsistency among studies needs further evaluation.

Summary: Understanding the dominant ecological processes during forest succession is important for forest conservation and restoration. This study investigated the community assembly processes during forest succession in southern China using phylogeny-based and functional trait-based indicators. Results showed that both the community phylogenetic and functional trait structures changed during succession. Environmental factors and species richness had significant effects on the community assembly processes. The relative importance of ecological processes changed during succession, with environmental filtering dominating in early succession and both environmental filtering and competitive exclusion having important effects in later succession.

Summary: Introducing nitrogen-fixing tree species into Eucalyptus plantations can maintain high levels of nitrogen consumption and productivity, but may exacerbate phosphorus limitation. A field experiment was conducted to investigate the impacts of nitrogen fertilization and introducing a nitrogen-fixing tree species on soil phosphorus transformation in a pure Eucalyptus plantation. Nitrogen fertilization significantly increased the occluded phosphorus pool and reduced other phosphorus pools, while introducing the nitrogen-fixing tree species did not change soil pH or the nitrogen:phosphorus ratio in Eucalyptus leaves.

Summary: Climate change has affected precipitation patterns and prolonged drought season in subtropical areas, leading to changes in forest productivity and soil carbon cycling. This study investigated the response of different soil organic carbon fractions to reduced precipitation in a subtropical forest, and found that particulate organic carbon (POC) decreased but mineral-associated organic carbon (MAOC) increased in the topsoil with reduced precipitation. Additionally, microbial biomass carbon, dissolved organic carbon, fine-root biomass, and mycorrhizal fungal biomass were all reduced. The findings highlight the importance of fine roots in mediating the response of different soil carbon fractions to precipitation reduction in subtropical forests.

Summary: Drought events have significant impacts on terrestrial ecosystems, and understanding recovery mechanisms is critical for predicting ecosystem dynamics. In a 7-year field precipitation experiment, we found that a grassland ecosystem showed different recovery abilities from sustained drought of varying magnitudes. After extreme drought, aboveground net primary productivity (ANPP) and perennial forb biomass significantly decreased (-43.3% and -83.1%). However, ANPP fully recovered within a year after the drought treatments ended, mainly due to increased soil nitrogen and root biomass. Surprisingly, ANPP increased during the recovery period, exceeding the control, primarily due to increased biomass of perennial grasses. Our study highlights the rapid recovery of grasslands and the importance of community overcompensation in maintaining ecosystem function and stability.

Summary: Elevation has a strong effect on the aquatic microbiome, affecting the abundance and composition of functional genes. This study found that high-altitude lakes had a higher abundance of antibiotic resistance genes and organic remediation genes compared to low-altitude lakes. Additionally, the composition and abundance of metal resistance genes varied between the two altitudes. The enrichment of functional genes in high-altitude lakes is likely influenced by different microbial communities and long-range atmospheric transport of exogenous genes and pollutants.

Summary: Climate warming has a profound impact on terrestrial biosphere, but the effects of asymmetric rising temperatures between daytime and nighttime on soil microbial communities remain unclear. Long-term asymmetric diurnal warming decreased fungal abundance and the ratio of fungi to bacteria, while short-term warming showed no significant effect. The changes in microbial composition had a greater influence on soil respiration than microbial biomass, indicating the importance of microbial composition in modulating carbon release under long-term climate warming.

Summary: Human disturbance affects the community structure and spatial distribution of forest soil seed banks on coral islands, increasing the diversity, richness, and density of seed banks as well as the richness of invasive species. Human disturbance alters the dispersal pattern of seeds, limiting the outward dispersal of resident species and promoting the inward dispersal of invasive species. Soil properties, plant characteristics, and human disturbance explain 23-45% of the spatial variation of forest soil seed banks on coral islands, with human disturbance reducing the correlations between plant communities and soil factors while increasing the correlations with landscape heterogeneity, road distance, and shrub and litter cover.

Summary: Canopies play a crucial role in redistributing nitrogen in forest ecosystems, and not considering their influence can lead to biased estimates of the ecological consequences of human-induced nitrogen deposition. This study investigated the effects of different approaches and levels of nitrogen addition on microbial residual carbon (MRC) accumulation in a tropical forest. Results showed that the response of MRC to nitrogen addition varied with soil depth, with contrasting effects in the topsoil and subsoil. Understory nitrogen addition had greater effects on MRC accumulation compared to canopy nitrogen addition. These findings highlight the important role of canopies in mitigating the impacts of nitrogen deposition on soil carbon cycling in tropical forests and the need for further research on depth-dependent response mechanisms.
