Despite reports of relative stability of cryoconite hole community composition on the Greenland Ice Sheet, it is not known how microbial function in cryoconite holes evolves under varying environmental conditions. Here, we address this knowledge gap by quantifying the active community members in five cryoconite holes on the Greenland Ice Sheet over a 3-week period during the 2022 melt season using TotalRNA. Active microbiomes were enriched in cyanobacterial sequences (25%-50%). Spatial variation between cryoconite holes had a greater impact than temporal variation on community composition quantified by rRNA SSUs, suggesting location-distinct and highly stable active microbiomes. In contrast, minor temporal variations in gene expression were identified in the mRNA data (∼1% of quantified transcripts), mostly due to cellular stress responses from washed-in glacier ice algae. Photosynthesis was the dominant active function across all surveyed cryoconite holes and time points, associated with both cyanobacterial taxa and washed-in chlorophyte snow algae. Overall, our data indicate that core cryoconite hole communities stably ensure their ecological roles, such as carbon fixation, regardless of variations in weather, highlighting their resilience and self-sufficiency.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13390577/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148404115","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 assemblages within these systems also contribute substantially to broader biogeochemical cycling. Gaining a detailed understanding of the functional potential and abundance of microorganisms responsible for nitrogen (N) and phosphorus (P) transformations is therefore crucial for evaluating nutrient remediation efficiency. In this study, we integrated high-throughput 16S rRNA sequencing with a GeoChip functional gene array to investigate how microbial community dynamics correspond to nutrient fluctuations in full-scale RAS. A suite of multivariate statistical approaches, including ordination and network-based analyses, was applied to characterize shifts in both taxonomic structure and functional gene profiles across operational phases. Our results revealed clear temporal patterns in functional gene abundance. Denitrification-related genes (nosZ, napA, nirK/S) became more prominent toward the later stages of operation, while nitrification genes (amoA/B) were most abundant early in the cycle and declined thereafter. Genes involved in ammonification (ureC) and several P-cycling genes (phnK, phoD, phoX) also increased notably during the final phase. These trends underscore the close relationship between bacterial community succession, species turnover, and nutrient cycling capacity. Overall, the study enhances current understanding of functional microbial dynamics in RAS and provides insights that could guide the development of improved nutrient management and bioremediation strategies for aquaculture systems.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13421783/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148591028","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 evaluated its hypothesized disruptive effects on nestling gut microbiota and explored also whether the effects depend on sibling relatedness using a partial cross-fostering design.

The experimental parasite manipulation also affected the relative abundance of 123 bacterial strains, including fermenters, mucosa-adapted bacterial symbionts, and opportunistic pathogens. Finally, gut microbiota composition was also associated with nestling phenotype (body mass, wing and tarsus length, carotenoid concentration, and telomere dynamics). Sparse PLS network analyses linked body mass (positively: Erysipelatoclostridium, Parabacteroides, and Helicobacter; negatively: Salmonella) and parasitism intensity (negatively: Dubosiella, Rickettsiella, and Helicobacter) with relative abundance of specific bacterial strains.

However, the effects of local hydrogeochemical factors (e.g. O2, electron donors, carbon sources) on the abundance of denitrifiers remain poorly understood. To address this, we sampled planktonic (0.2-0.4 µm, 0.4-8.0 µm) and particle-associated (>8 µm) biomass from nine groundwater wells and one karstic spring in the Ammer River catchment (SW Germany). Comparing groundwater hydrochemistry with microbial community composition and the relative abundance of 16S rRNA and N-cycling genes (nirK, nirS, amoA) revealed a correlation between declining O2 and dissolved organic carbon levels in the aquifer and lower bacterial and archaeal 16S rRNA gene copy numbers. Despite oxic conditions in the recharge zone, NO3⁻ could be reduced heterotrophically and autotrophically in anoxic microniches. In the confined anoxic zone, taxa such as Aquabacterium, Acidovorax, and Gallionella could couple NO3⁻ reduction to pyrite-derived Fe(II) oxidation. Microorganisms such as Rhodoferax, Sediminibacterium, and Sulfurifustis could oxidize pyrite-derived reduced sulfur compounds. Hydrogen-oxidizing (e.g. Hydrogenophaga) and CH4-oxidizing microorganisms (e.g. Candidatus Methylomirabilis) could also contribute to NO3⁻ turnover. These findings suggest that the turnover of NO3- in the carbonate aquifer shifts from pathways predominantly supported by organic matter in recharge groundwater towards an increasing reliance on pyrite-derived electron donors under anoxic conditions.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13377637/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148351429","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}

This study aimed to evaluate the efficacy of choline pelargonate (CP) against grapevine downy mildew and powdery mildew under controlled and field conditions, and to assess its effects on phyllosphere micro-organisms. CP decreased the severity of both pathogens under greenhouse and field conditions. In greenhouse trials, 16 mM CP showed efficacy comparable to copper and sulfur applied at label-recommended concentrations as reference fungicides in organic viticulture. CP showed direct inhibitory activity against both pathogens, and slightly induced defense-related grapevine genes (CHIT-3, OSM-2, and PR-1). Field experiments corroborated the efficacy of CP against powdery mildew and downy mildew severity on leaves and bunches. Microbial community analysis revealed that plant compartment, vineyard location, and sampling time were key drivers of microbial community structure, while treatments showed negligible effects on microbial alpha-diversity and beta-diversity of grapevine leaves and bunches. CP treatment partially modified the relative abundances of some bacterial and fungal taxa, while reference fungicides caused broad changes across multiple genera. CP showed promising antifungal activity with minimal effects on phyllosphere micro-organisms, supporting its potential as a sustainable disease management approach that preserves indigenous microbial communities.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13436970/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148577921","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}

A core microbial community was established within ∼3 years and persisted for up to ∼100 years. Alpha diversity declined with soil age and was lowest in the oldest soils (Shannon: 4.8 ± 0.4 to 4.0 ± 0.2). Community composition showed strong and consistent turnover across the chronosequence, with age and soil geochemistry jointly explaining 19% of variation. Bacterial assemblages were dominated by Actinobacteriota, Chloroflexi, and Pseudomonadota, while archaea comprised 3.3%-9.5% of total abundance and were mainly dominated by Thermoproteota and Thermoplasmatota. Increasing soil age was associated with higher total organic carbon, greater abundance of oligotrophic taxa, and higher bacterial 16S rRNA gene copy numbers. Functional predictions indicated a transition from labile carbon turnover in young soils to enhanced potential for complex organic matter degradation in older soils.

Homogeneous selection predominated in Good and Regular WQI sites but declined markedly under Poor WQI conditions, where drift and dispersal limitation became the dominant assembly processes. These results indicate that extreme pollution alters the nature of environmental filtering, favoring disturbance-tolerant functional traits distributed across phylogenetically diverse taxa and increasing the influence of stochastic assembly. Consequently, taxonomic composition becomes less predictable from local environmental conditions.
