We conducted a field experiment with four legume species subjected to light and shade treatments, with and without rhizobial inoculation, to assess plant survival, biomass accumulation, nodulation, nitrogen acquisition, and isotopic signatures, alongside microbial community diversity and shifts in vegetation composition. Results demonstrate that inoculation significantly enhanced survival, growth rates, nitrogen accumulation, and nodulation across species, particularly under light conditions, indicating that microbial symbiosis promotes acquisitive strategies within the PES framework. Contrary, shaded environments consistently favoured higher survival and root allocation but reduced growth, nodulation, and nitrogen fixation, reflecting more conservative resource-use strategies. Species-specific responses revealed differential PES positioning: Trifolium repens L. exhibited high acquisitive capacity under light, while Coronilla juncea L. showed poor survival and growth under both conditions, highlighting the interaction between phylogenetic identity and resource availability. Additionally, δ¹⁵N and %Ndfa values confirmed that inoculation increased nitrogen fixation efficiency, whereas microbial diversity analyses indicated strong shifts in soil bacterial communities associated with inoculated plants, suggesting feedback between symbiosis and soil microbiota. These findings support two main hypotheses: (i) rhizobial inoculation acts as a biotic driver promoting acquisitive strategies by enhancing resource acquisition and growth efficiency, and (ii) light availability serves as an abiotic axis that modulates species positions along the PES continuum. Together, our study provides novel evidence that both microbial interactions and resource availability jointly determine legume strategies within the PES.</p>","PeriodicalId":18708,"journal":{"name":"Microbial Ecology","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparing the microbiome of bees with different social roles and foraging behaviours may uncover the ways in which microbiota are environmentally acquired and subsequently introduced and spread into the nest environment. Here, we performed metabarcoding of the 16S rRNA, ITS, and ribulose biphosphate carboxylase large (rbcL) regions on mothers, dwarf eldest daughters, and regular daughters in nests of the facultatively social, small carpenter bee, Ceratina calcarata, contrasting bacteria, fungi, and plant associates. We also performed two different sampling types by characterizing the microbiome using whole-guts and whole-bodies. Social role in nest impacted the microbial community composition and mothers were found to demonstrate increased plant diversity compared to their daughters, more specifically in whole-bodies, highlighting the ability to determine plants that bees are visiting during foraging through DNA metabarcoding. We also found that metabarcoding of the whole-body recovered increased fungal and plant diversity compared to whole-guts, suggesting that including microbiota from beyond the gut offers an opportunity to characterize uncommon associates that bees encounter, particularly through plant-pollinator relationships.

Critical issues, including ecological fragility, complexity of pathogen transmission networks, and delayed responsiveness of control measures, are comprehensively analyzed.

This study investigated arsenic distribution, speciation, and detoxification mechanisms in three mushroom species of the genus Hebeloma: H. bulbiferum, H. sinapizans, and H. mesophaeum. Wild collected fruit bodies and laboratory mycelial cultures were analysed using size-exclusion chromatography (SEC) and ion-pair reversed-phase ICP-MS to determine total arsenic concentrations and speciation patterns. H. bulbiferum exhibited the highest arsenic accumulation in fruit bodies (up to 563 mg kg⁻¹ dry mass), predominantly as dimethylarsenate, whereas H. sinapizans accumulated less total As (up to 41.2 mg kg⁻¹ dry mass), comprising mainly arsenobetaine and dimethylarsenate, and H. mesophaeum (up to 4.2 mg kg⁻¹ dry mass) was dominated by inorganic arsenic and arsenocholine. SEC revealed that arsenic was present as low-molecular-weight fractions, although a minor protein-associated peak was observed in H. sinapizans, suggesting a possible presence of an arsenic-binding protein. Mycelial cultures demonstrated species-specific tolerance to arsenate and the ability to transform inorganic arsenic into organic arsenicals, with varying degrees of arsenate reduction, arsenite efflux, and methylation. In particular, H. sinapizans and H. mesophaeum exhibited a higher degree of As(III) efflux than H. bulbiferum, indicating a more efficient As reduction and export. Notably, some organoarsenicals, dimethylarsenate and trimethylarsine oxide, were actively excreted into the growth medium, indicating a role for mushroom mycelia in environmental arsenic cycling. These findings highlight distinct arsenic detoxification strategies in Hebeloma species, reveal fungal de novo arsenobetaine synthesis, and provide insights into arsenic transformation and sequestration in ectomycorrhizal mushrooms.</p>","PeriodicalId":18708,"journal":{"name":"Microbial Ecology","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147840094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To manipulate the microbiome, we developed a chemical treatment protocol to surface sterilize C. maculatus eggs and the food source on which they develop and examined the effect on microbial community structure, beetle life history traits, and mating behaviors including mate choice, and locomotion. Treatment eliminated culturable bacteria from the surface and altered the emerged adult beetle microbiome such that diversity was reduced and the community structure was altered. Treatment reduced survival of small male and female beetles; among the adults that did survive and emerge, females had higher fecundity compared to controls. We found that the treatment also affected mating behavior. Treated beetle pairs had a higher percentage of successful matings and a shorter mating latency period than control beetles. In mate choice tests in which a female was presented with either a treated or control male, females were more likely to mate with treated males. Finally, treated beetles exhibited increased locomotion. Treatment caused selective mortality of smaller individuals and reduced the diversity and altered the structure of the whole-body microbiome of the surviving adults. The treatment was also associated with enhanced mating behavior, increased fecundity and increased locomotion.
