Soil microorganisms play an essential role in vegetation succession, nutrient cycling, and ecosystem restoration. This study investigates the responses of soil microbial communities to ecological transitions from forest wetland Lesser Khingan Mountains, including mixed forest, conifer edge, natural wetland. The results indicated that soils were weakly acidic contained significantly higher organic matter, total nitrogen, available phosphorus compared other soils. bulk density increased with depth. Actinobacteria, Acidobacteriota, Proteobacteria dominated soils, respectively, showing minimal variation between depths. Principal component analysis non-metric multidimensional scaling demonstrated distinct bacterial wetlands edges. Redundancy revealed differed 15 cm 30 layers, influenced by potassium, density, carbon, phosphorus, nitrogen. Bacteroidota abundances correlated positively nutrients, while Acidobacteriota Verrucomicrobiota negatively potassium. Chemotrophic aerobic bacteria whereas fermentation-related anaerobic prevalent highlights how properties shape their functions.

Arbuscular mycorrhizal fungi (AMF) and ectomycorrhizal (EMF) form ubiquitous symbiotic relationships with plants through co-evolutionary processes, providing multiple benefits for plant growth, productivity, health, stress mitigation. Mountain ecosystem multifunctionality is significantly influenced by responses to climate change, highlighting the importance of understanding complex interactions between these environmental variables. In this study, we investigated five vegetation zones across an altitudinal gradient (675-2157 m a.s.l.) in Wuyi Mountain, one most well-preserved mid-subtropical mountain ecosystems eastern China. Using high-throughput sequencing, examined distribution patterns, community assembly mechanisms, network soil AMF EMF. Our analyses demonstrated significant variations composition diversity fungal communities. richness peaked subalpine dwarf forest at intermediate elevations, whereas EMF was highest low-altitude evergreen broad-leaved forest, showing a marked decrease alpine meadow ecosystem. β-diversity decomposition revealed that species turnover constituted primary mechanism differentiation both types, explaining >56% observed variation. Stochastic processes dominated assembly, relative dispersal limitation drift distinct patterns. Network analysis indicated networks reached maximum complexity forests, while showed similar levels coniferous forests. Among factors, properties emerged as predominant driver multifunctionality, followed communities climatic These findings provide critical insights into ecological functions adaptations fungi, advancing our their changes informing evidence-based conservation strategies.

Summary The development of terrestrial ecosystems depends greatly on plant mutualists such as mycorrhizal fungi. global retreat glaciers exposes nutrient‐poor substrates in extreme environments and provides a unique opportunity to study early successions fungi by assessing their dynamics drivers. We combined environmental DNA metabarcoding measurements local conditions assess the succession communities during soil 46 glacier forelands around globe, testing whether drivers differ between types. Mycorrhizal colonized deglaciated areas very quickly (< 10 yr), with arbuscular tending become more diverse through time compared ectomycorrhizal Both alpha‐ beta‐diversity were significantly related since communities, while microclimate primary productivity important for richness composition also explained chemistry, highlighting importance microhabitat community dynamics. acceleration ice melt modifications forecasted climate change scenarios are expected impact diversity partners. These changes could alter interactions underlying biotic colonization belowground–aboveground linkages, multifaceted impacts associated ecological processes.

Soil bacteria, the predominant microbiota in soil, are subject to law of minimum and tolerance, but assembly patterns soil bacteria response environmental factors remain far from clear. Here, we took advantage an altitudinal gradient (1020-1770 asl) oak-dominant forests assessed whether linearly or nonlinearly respond properties through changes community diversity composition. We found that decreased with increasing altitude terms species richness phylogenetic structure, while they were unchanged The was affected by pH (19.9%), C:N ratio (14.3%), SOC (11.4%), silt + clay content (9.9%). Specifically, peaked at a 5.5-6.5, 25-50 g kg
