Summary: Trees and their associated fungi play a crucial role in carbon and nitrogen cycling. The dominance of different types of mycorrhizal fungi in the soil affects nitrogen availability and cycling. The study found that ectomycorrhizal trees reduce net nitrogen mineralization by producing recalcitrant litter and depleting nitrogen directly from soil organic matter. Additionally, the low pH and high C:N ratio in ectomycorrhizal-dominated soils inhibit ammonia-oxidizers and decrease net nitrification rate.

Summary: Research showed that the growth response of one type of phytoplankton to warming could be weaker under nutrient-limiting conditions than in nutrient-replete waters, while the other type of phytoplankton's growth was less affected by nutrient supply scenarios. The temperature sensitivity of half-saturation constants and the level of nutrient limitation may counteract the response of one type of phytoplankton growth rate to increasing temperature.

Summary: The study revealed that soil bacterial diversity increased over time since restoration, with community compositions shifting towards those of old-growth forests. The recovery process was prolonged, as significant differences in bacterial diversity between degraded and restored forests did not occur until after 24 years since restoration. Soil properties such as carbon, water content, and pH played a significant role in explaining variations in bacterial community dynamics following restoration.

Summary: Diazotrophs play a key role in nitrogen cycling in tropical/subtropical forests, but little is known about the dynamics of diazotroph communities during forest succession. The study found that diazotrophic diversity increased with forest succession in one chronosequence, while relative abundance of the dominant genus Bradyrhizobium was influenced by soil phosphorus concentration. Soil phosphorus availability was identified as a crucial factor in mediating diazotroph community composition during forest succession in subtropical forests.

Summary: The persistence of soil organic carbon (SOC) is influenced by microbial metabolic activities, but how microbial effects on SOC sequestration are affected by soil nutrient status remains unclear. This study found that higher nutrient availability promoted the production and accumulation of microbial necromass, enhancing SOC accumulation in fertile soil. In contrast, nutrient deficiency led to preferential resource allocation to stress-tolerant fungi and Gram-positive bacteria, resulting in SOC loss in infertile sand.

Summary: Global changes can alter plant inputs and affect soil carbon and microbial communities in forests. A meta-analysis of 166 experiments worldwide revealed that alterations in aboveground litter and/or root inputs had profound effects on soil carbon and microbial communities. Litter addition stimulated soil organic carbon (SOC) pools and microbial biomass, whereas removal of litter, roots or both (no inputs) decreased them. The responses to litter alterations positively correlated with litter input rate and total litter input.

Summary: This study investigates the effect of nitrogen addition on forest soil bacterial communities, dissolved organic matter (DOM) components, and their relationships. The results show that low levels of nitrogen addition lead to eutrophication of the surface bacterial community and a decrease in diversity. Short-term nitrogen addition decreases dissolved organic carbon content but increases DOM humification degree. Key bacterial taxa are associated with specific DOM components, and nitrogen addition helps regulate the interactions between soil bacterial communities and DOM.

Summary: This study combines two experiments and a meta-analysis to investigate the priming effect (PE) of soil organic carbon (SOC) and its relationship with SOC stability. The results show that the PE increases with the prolongation of soil preincubation, indicating that stable SOC is more vulnerable to PE compared to labile SOC. The meta-analysis supports this finding and reveals that soil C availability plays a crucial role in regulating the difference in PE between labile and stable SOC. These findings highlight the importance of considering the vulnerability of stable SOC to priming in future studies on SOC cycling and global change.

Summary: Elevated nitrogen deposition affects soil phosphorus (P) composition and availability in subtropical forests. Wet season nitrogen deposition reduces labile and organic P content, while increasing NaHCO3-Pi content. Acid phosphatase and root P content are the primary factors affecting soil P in the wet season, while organic-bound Fe (Fe-p) and NO3--N concentrations are key factors in the dry season.

Summary: This study demonstrates the importance of microbial community-level properties and keystone taxa in the priming effect and decomposition of soil organic matter. Single carbon addition induced a greater priming effect compared to repeated carbon additions, and the shifts in fungal/bacterial dominance play a crucial role in regulating the priming effect. Sufficient carbon facilitates the proliferation of r-strategy bacterial taxa and saprophytic fungal taxa, leading to increased soil organic matter decomposition.

Summary: The structure and function of plant communities in alpine meadow ecosystems are influenced by climate warming, as shown in a field manipulation experiment on the Qinghai-Tibetan Plateau. The experiment revealed that plant species diversity, biomass, and net primary productivity generally resisted warming, but plant community composition gradually changed. Legumes' biomass significantly decreased by 45%, while forbs' biomass increased by 84% due to favorable growth conditions. Overall, short-term warming can affect plant community composition by altering interspecific competition and survival strategies, leading to changes in plant productivity and carbon dynamics in alpine meadow ecosystems.
