While impacts on vegetation are increasingly documented, effects on belowground microbial communities and ecosystem processes remain poorly studied. We investigated how experimental drought and warming influence soil microbial communities and decomposition across a 900-m elevation gradient in the tropical montane forests of the Dominican Republic. Precipitation exclusion shelters simulated drought at high (2250 m a.s.l.) and low elevation (1350 m a.s.l.) and high elevation soils were translocated to the lower elevation to simulate warming. Fungal and bacterial communities were measured by DNA sequencing over 11 months, in addition to soil properties and litter decomposition. Fungal richness increased under drought but was unchanged following translocation, whereas bacterial richness and abundance were largely unaffected by either treatment. Decomposition was consistently faster at the lower (warmer) site but slowed under intense drought at both elevations. Soil carbon was higher at high elevation, consistent with slower decomposition. Overall, these results indicate cooler and wetter conditions promote structurally and functionally complex fungal communities. As temperature and precipitation patterns change, fungal communities are more likely to shift in response, altering decomposition and nutrient cycling, with implications for carbon storage in tropical montane ecosystems, especially at high elevations.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13673987/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149164187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that volatile organic compounds might help maintain the mutualisms between beetles and specific fungal partners. Here, we compared the volatiles emitted by 30 fungi known to act as mutualists, commensals or antagonists for their beetle hosts. GC-MS analysis showed that all the fungi had characteristic volatile profiles with beneficial fungi emitting a greater diversity of volatiles than other fungal species. The volatile profiles of beneficial fungi were dominated by aliphatic and aromatic alcohols and esters in terms of both diversity and abundance. Furthermore, we demonstrated that the larvae and adults of two ambrosia beetle species can distinguish their mutualistic fungi from others based on volatile cues. Our results highlight the importance of aliphatic and aromatic alcohols and esters as recognition cues for mutualist fungi by wood-boring beetles.

Here, we combined hydrogeochemical profiling, 16S rRNA gene amplicon sequencing, indicator species analysis, null-model inference, and predictive functional profiling to characterize community composition, assembly processes, and functional potential across 88 samples at South Sumujaran Lake, Badain Jaran Desert, China. The samples spanned fresh groundwater in two transects, brackish-to-saline groundwater in the transition zone, and hypersaline lake water along a hydrologically connected continuum, covering a more than 300-fold range in salinity. Despite hydrological connectivity, lake water communities were almost completely distinct from those in the two groundwater transects and the transition zone. The transition zone also supported a distinct set of indicator taxa, suggesting that its community composition was not explained by mixing alone. Assembly processes shifted along the continuum: dispersal limitation was the most prevalent process system-wide and occurred within the two low-salinity groundwater transects but not in the transition zone or hypersaline lake, whereas homogeneous selection increasingly structured communities toward these higher-salinity zones. Predicted functional profiles differed little between the two groundwater transects but markedly between groundwater and lake water.

We investigated how source identity, moraine age, and topography shape microbial assembly across four glacier forefields in the high-altitude desert of Ladakh, India (northwestern Himalaya). Using a chronosequence approach integrating vegetation surveys, soil physicochemistry, GIS-derived topographic variables, and amplicon sequencing, we found that source identity was the primary driver of microbial diversity and composition.

Bacterial-fungal congruence was significant in all sources except bulk soil, indicating stronger inter-kingdom coupling in host-associated habitats than among soil environments. Source exclusion consistently altered microbial co-occurrence network structure, revealing potential ecological roles among sources, with cryptogams supporting microbial connectivity and vascular plants promoting more specialized interactions.

However, precipitation trajectories are spatially heterogeneous across alpine meadow regions, and the direction and mechanisms underlying SOC responses to warming-wetting conditions remain uncertain. While traditional frameworks emphasize plant litter inputs, emerging evidence highlights the central role of microbial processes in SOC stabilization. Arbuscular mycorrhizal fungi (AMF), which are widely distributed in alpine meadow ecosystems, mediate plant-derived carbon (C) transfer into soils and may regulate SOC formation, turnover, and stabilization. This review synthesizes current knowledge on how warming and increased precipitation influence SOC stocks and dynamics in alpine meadows, with a focus on AMF-mediated mechanisms. We highlight how AMF regulate belowground C inputs, priming effects, and microbial metabolism, thereby affecting SOC accumulation and stabilization. Evidence indicates that warming and altered precipitation jointly modify SOC turnover by influencing plant-AMF C allocation, AMF community composition, microbial C use efficiency, and enzyme activities. These responses are strongly context dependent.We propose an AMF-mediated biotic C pump (BCP) under warming and wetting, emphasizing the role of AMF in promoting the incorporation and stabilization of newly fixed C in soils. This framework advances understanding of C cycling and improves predictions of ecosystem feedbacks to climate change.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":"102 10","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13640030/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149106316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbial richness declined with depth, and core taxa including Rice Cluster II, Terriglobales, Subgroup 2, Roseiarcus, Methylocystis, and Candidatus Solibacter were shared across locations. Functional gene profiles revealed depth-related reorganization of carbon-cycling potential, with hydrolytic and fermentative functions relatively more abundant near the surface and acetogenic and methanogenic pathways more prominent in deeper anoxic horizons.
