Volcanic lava is an excellent model of primary succession, in which basalt-associated microorganisms drive the cycling different elements such as nitrogen, carbon, and other nutrients. Microbial communities volcanic soils are particular interest for study on emergence evolution life within special extreme conditions. The initial processes colonization subsequent rock weathering by microbial still poorly understood. We analyzed soil bacterial fungal diversities associated with (LBL) kipuka (BK) sites Wudalianchi using 16S ITS rRNA Illumina Miseq sequencing techniques. results showed that physical chemical properties (pH, MC, TOC, TN, TP, AP, DOC, DON) significantly differed between LBL BK. Shannon, Ace, Pd indexes fungi two a significant difference (p < 0.05). dominant phyla forming at BK were Acidobacteria, Proteobacteria, Actinobacteria, Basidiomycota, their differences driven Gemmatimonadetes Verrucomicrobia.

Heavy metal (HM) contamination affects the composition and structure of soil microbial communities, but there are few studies on assembly process co-occurrence network community succession driven by Cd in volcanic ecosystem. To address this gap knowledge, we collected analyzed samples from Nvshan Volcanic area to understand characteristics primary (PS) secondary (SS). We found that was contaminated with different levels (PS > SS), resulting obvious heterogeneity microorganisms. The absolute abundance bacteria (16S rRNA gene copies) varied significantly between two successions (P < 0.0001). networks analysis showed number nodes bacterial communities lower PS compared SS (1002 vs. 1004), indicating heavy would reduce communities. Compared PS, exhibited stronger competitiveness (positive: negative, P/N: 25.69 64.22), whereas fungal were closer symbiotic relationships (positive/negative, 15.85 14.29). neutral model (NCM) revealed stochastic processes predominantly governed (bacterial R2: 0.657, 0.686). Mantel test negatively associated cbbLR, amoA, phoD. results Sankey diagram fungi more resistant than (27 13). This study contributes understanding under stress identifying strains potential for remediation.

The variation in the soil microbial community along altitude gradient has been widely documented. However, structure and function of communities distributed crater still need to be determined. We gathered specimens from different elevations within Nushan volcano bridge this knowledge gap. investigated bacteria fungi soil. It is noteworthy that alpha diversity peaks middle crater. network analysis shows bacterial (nodes 760 vs 613 601) fungal 328 224 400) are most stable at bottom top crater, respectively. Furthermore, exhibited a decline, followed by an increase across varying altitudes. core microorganisms displayed highest correlation with pH alkaline phosphatase (AP, as determined through redundancy (RDA) Mantel tests for analysis. higher number microorganisms, while demonstrate greater susceptibility environmental factors. In conclusion, we utilized Illumina sequencing techniques assess disparities soil.IMPORTANCEThese findings serve foundation future investigations on present volcanic

Hydrothermal biochar has demonstrated potential in enhancing crop growth by improving soil properties and microbial activity; however, its effectiveness varies with application rate, excessive amounts potentially inhibiting plant growth. This study employed a pot experiment approach to compare varying rates of hydrothermal (ranging from 0 50 t/ha) analyze effects on alfalfa biomass, photosynthetic efficiency, nutrient content, community composition. Biochar increased dry weight 12.22-21.20% leaves, 31.60-55.60% stalks, 5.62-38.05% roots. It also enhanced the light utilization efficiency photosystem II. However, (50 reduced biomass photosynthesis. The addition amendments enhances availability, particularly increasing accessibility carbon, nitrogen, phosphorus, while lowering pH enriching interactions within bacterial communities. fungal communities are not pronounced. In conclusion, moderate (10-20t/ha) is recommended maximize improve health, offering practical for sustainable cultivation alfalfa.
