Honeydew supports a wide range of organisms, including ants, pollinators, (hyper-)parasitoids wasps, predatory insects, and microbes. As a sugar-rich resource, honeydew is frequently colonized by specific microbes (i.e. bacteria and fungi), which consume its sugars and other nutritional constituents. Recent research suggests that microbes within honeydew may modify its traits. Thereby driving microbial succession and acting as important 'hidden players' in multitrophic ecological interactions. Yet, its role as a dynamic microbial habitat remains largely unexplored. Here, we synthesize current evidence on the microbial ecology of honeydew and propose that honeydew is a dynamic rapidly changing microbial habitat. We further propose a four-stage successional model to frame its temporal dynamics. We discuss how the honeydew microbiome alters nutritional composition. Further, we discuss how the honeydew microbiome may mediate multitrophic interactions through the emission of volatile organic compounds that attract natural enemies of honeydew-producing insects. We propose that this process may pose a trade-off between the microbial secondary metabolism and its dispersal capacity of some microbes. We aim to stimulate research that will establish honeydew microbial ecology as a new frontier in plant-insect-microbe interactions.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13587098/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148911402","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}

One potentially important yet largely overlooked source of carotenoids is host-associated microbes. Microbially derived carotenoids may influence host phenotype and physiology, but the extent to which they occur or vary across hosts remains largely unknown. To begin to address this gap, we isolated gut-associated bacteria from multiple wild sauropsids. We cultured 157 distinct bacterial isolates from 25 individuals representing eight host species; 21% of isolates were yellow- or orange-pigmented and 40% exhibited absorbance spectra consistent with the presence of carotenoids. 16S rRNA gene sequencing revealed that isolates spanned four phyla and 35 genera. Isolates that were consistent with the presence of carotenoids were found across all four phyla, with Pantoea being the most common carotenoid-associated genus. Host species did not significantly explain variation in isolate community composition. These results demonstrate that carotenoid-capable bacteria are both taxonomically diverse and widespread among gut-associated bacteria from wild sauropsids. More broadly, our findings provide insight into a hidden dimension of host-microbe interactions and their potential function.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13599784/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904538","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}

It impacts soil chemistry, vegetation, and soil organisms, yet little is known about its long-term impacts on soil microbial communities. Here, we focus on the long-term impacts of ash fertilization on the soil microbiome of drained boreal peatland forests in Finland. We hypothesized that the ash-induced changes in soil chemistry have led to long-term changes in soil microbial communities. To study this, we analyzed soil bacterial and archaeal communities from seven drained peatland forest sites in Finland. Each site had an ash fertilized plot (fertilized 8-43 years before sampling) and an unfertilized plot. Soil pH was higher at ash fertilized plots in five out of the seven sites. Pseudomonadota, Bryobacteraceae, and Planctomycetaceae were more abundant in samples from the control plots, whereas Actinomycetota were more abundant in samples from the ash fertilized plots. According to distance-based redundancy analysis, soil pH was important driver of soil bacterial and archaeal community structure. Site explained a greater proportion of community variation than treatment. Therefore, impacts of wood ash on soil in peatland forest stands should be considered by taking into account their site-specific factors and management history.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13592162/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148918611","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}

Pathogenic species are responsible for nosocomial infections, which are increasingly difficult to treat due to growing resistance to antibiotics. In addition to nosocomial settings, ACB complex has also been found in other environmental niches, including animals, food, soil, and water, where human activity has contributed to the development of antibiotic resistance. For instance, improper disposal of solid waste and release of wastewater effluent carrying antibiotic-resistant pathogens have introduced antibiotic resistance genes into the natural environment. Additionally, soil and water environments near agricultural operations are hotspots for ACB complex strains and antibiotic resistance. Antibiotic resistant ACB complex are also transmitted through food production system. While antibiotic resistance level in strains from healthy animals is low, it can be highly prevalent on meat. Meat and produce fertilized by manure from antibiotic-treated animals are a pathway for transmission of ACB complex back to human and clinical environments, reflecting the interconnectedness of humans, animals, and the environment. This review has revealed research gaps, particularly on non-Acinetobacter baumannii ACB complex species in the environment.

We analysed how the removal of plant species, with and without urea addition, influenced plant diversity, soil properties, and soil bacterial communities in a Tibetan Plateau grassland. Continuous plant species removal and urea addition over 7 years modified plant beta-diversity equally strong, while urea exerted a stronger negative effect on plant alpha-diversity. Both, plant species removal and urea addition caused soil acidification and an increase in NO₂⁻/NO₃⁻, while dynamics in total organic carbon and total organic nitrogen were mainly driven by the growing season. Structural equation modeling identified soil acidification via urea addition as the most important indirect driver that negatively affected bacterial alpha-diversity and shifted bacterial beta-diversity. Urea addition also exerted direct negative effects on bacterial alpha- and beta-diversity, causing repression of oligotrophic (Acidobacteriota, Chloroflexota, Planctomycetota, and Gemmatimonadota) and stimulation of copiotrophic (Bacillota, Bacteroidota, and Pseudomonadota) bacterial taxa. Plant species removal caused slight increases in bacterial alpha-diversity, paralleled by less diverse but more even plant communities.

This study assessed the microbial community diversity and structure in taxonomically diverse co-occurring lichens associated with Trebouxiophyceae algae from Bolivian forests. We focused on three components of the lichen holobiont: the lichenized fungus (mycobiont), its associated algal (photobiome), and fungal (mycobiome) communities. We specifically tested the influence of mycobiont identity, lichen thallus morphological type, reproductive strategy, and secondary metabolites composition on the lichen-associated photobiome and mycobiome. To understand the specialization patterns between holobiont components, we investigated biotic interactions between the mycobiont and the lichen-associated photobiome and mycobiome using network analysis. We observed that co-occurring lichens host diverse, host-specific, yet overlapping photobiomes and mycobiomes. In particular, these microbial communities are influenced by the host's thallus morphological type and its secondary metabolite content.

Here we used a space-for-time approach in clearcuts of fertilized and unfertilized forests to study the dynamics of soil fungal communities after clearcutting. We re-analysed data on fungal communities in the soil organic layer of 48 clearcuts in Sweden, spanning 1-13 years post-harvest. Clearcuts of previously fertilized forests were paired with clearcuts of unfertilized forests with similar characteristics. Ectomycorrhizal fungi disappeared after clearcutting, while saprotrophic fungi initially increased in abundance and subsequently decreased as ectomycorrhizal fungi reappeared. This effect was especially pronounced for saprotrophic agaricomycetes (Mycena, Luellia, and Trechispora) and in clearcuts of fertilized forests. We conclude that certain saprotrophic agaricomycetes respond to a transient release from Gadgil suppression by ectomycorrhizal fungi and/or an increase in substrate availability after clearcutting. Saprotrophs were particularly prolific in previously fertilized stands, in line with rapid disappearance of additionally accumulated belowground organic matter, whereas ectomycorrhizal fungal communities were little impacted by previous fertilization during the first decade after clearcutting.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13492344/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148668833","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}
