In this study, we investigated the interaction of prokaryotic and eukaryotic microbial communities in riverine ecosystems under temporal dynamics using high-throughput sequencing and co-occurrence network analysis. We observed distinct patterns, with eukaryotic communities showing a consistent increase in alpha diversity, while prokaryotic communities exhibited more variable and directional shifts over time. Two key phases were identified: a dynamic phase characterized by rapid changes in both alpha and beta diversity and a stabilization phase where community composition became more stable, with increased evenness. Co-occurrence network analysis revealed a transition from a modular structure in the dynamic phase to a more centralized and highly connected network in the stabilization phase. While modularity can enhance stability by localizing perturbations within distinct subnetworks, increased centralization and connectivity may weaken this stabilizing effect, potentially making the network less resilient to environmental fluctuations.

We collected stemflow from 18 Fagus grandifolia (American beech) trees during ten storms in northeastern Ohio (USA) and analyzed 18S rRNA eDNA to resolve transported microbial-eukaryote communities. Over 12 million reads (83 samples) revealed 920 zero-radius OTUs spanning fungi, algae, protists, and metazoans. Community composition differed significantly among storm events (PERMANOVA F = 3.6, r² = 0.31, p < 0.001) and among NOAA HYSPLIT modeled air-mass back-trajectories (F = 8.9, r² = 0.36, p < 0.001). Summer storms were dominated by fungal taxa (Entomophthoromycota, Basidiomycota, and Ascomycota comprised up to 90% of reads), whereas late-autumn and winter storms carried mainly algal stramenopiles (Ochrophyta). Large storms (> 60 mm event^-1) mobilized conspicuously higher relative abundances of larger metazoans (tardigrades and arthropods). We infer from stemflow eDNA that (i) seasonal resource shifts in tree canopies favor parasitic fungi in summer and saprotrophic fungi in autumn; (ii) northerly winter storms entrain Great Lakes aerosol algae that deposit onto canopies; (iii) rainfall intensity and duration jointly control the detachment of well-attached canopy eukaryotes.

Using a seasonal diversion project in a semi-enclosed bay as a case study, we analyzed phytoplankton composition via morphological methods and assessed carbon balance through simultaneous measurements of primary production (P), ecosystem respiration rate (R), and production-to-respiration (PP/R) ratio. Our results showed that artificial water diversion activities during the wet month enhanced hydrological connectivity and phytoplankton homogeneity, triggering a mixed diatom-dinoflagellate bloom. Phytoplankton abundance during the wet month increased by sevenfold (surface layer) and 26.5-fold (bottom layer) compared to dry month values. This simultaneously resulted in the PP value of the wet month being more than twice that of the dry month. Although R rose with increasing phytoplankton abundance, no significant correlation was observed between them. Instead, dry-month R was primarily driven by pH and dissolved organic carbon, whereas wet-month R showed minimal environmental linkages. PP/R ratios of surface and bottom layers were always less than 1, implying Meishan bay was a net heterotrophic ecosystem, despite significant changes in phytoplankton community structure induced by artificial water diversion and associated algal bloom. Furthermore, our results strongly suggest that changes in PP, but not in R, control the PP/R ratio of Meishan bay.

This study aimed to evaluate the antifungal potential of Bacillus subtilis ED24, an endophytic strain isolated from Ziziphus lotus (L.) roots, and its effects on wheat growth and yield under controlled conditions. In vitro assays demonstrated that B. subtilis ED24 inhibited F. culmorum mycelial growth by up to 87%, associated with the secretion of 37 distinct secondary metabolites, predominantly involved in carbon cycling. In pot experiments, B. subtilis ED24 significantly enhanced wheat germination (85%) and growth compared to infected plants treated with the chemical fungicide tebuconazole. Although nutrient analysis showed significantly higher shoot nitrogen (32.34 mg/pot) and phosphorus (2.41 mg/pot) contents in the B. subtilis ED24 treatment compared to tebuconazole (8.11 and 0.18 mg/pot, respectively), no significant differences were observed when compared to the infected control (C-). Similarly, B. subtilis ED24 led to improved thousand grain weight (40.4 g), protein content (19.98%), and ash content (1.95%) relative to tebuconazole (29.1 g, 18.31%, and 1.74%, respectively), yet these values did not differ significantly from the infected control (C-). Notably, the number of seeds per pot was significantly increased by B. subtilis ED24 compared to the infected control (C-) (113.8 seeds/pot vs. 54.2 seeds/pot). Additionally, B. subtilis ED24 modulated the wheat rhizosphere microbiome, enriching beneficial taxa such as Eurotiomycetes fungal class and the bacterial genus Paramesorhizobium.

However, to date, relatively few studies have focused on the response and mechanism of C. goreaui to the extreme high- and low-temperature stress. In this study, the responses and regulatory mechanisms of the dominant C. goreaui to extreme high- and low-temperature stress were investigated based on physiological indexes, transmission electron microscopy (TEM), and transcriptome analysis. The results showed that (1) under 34 °C heat stress, the disintegration of thylakoids triggered photosynthetic collapse in C. goreaui; survival is enabled through metabolic reprogramming that upregulates five protective pathways and redirects energy via pentose/glucuronate shunting to sustain ATP homeostasis, revealing a trade-off between damage containment and precision energy governance under thermal extremes. (2) Low temperature exposure induced suppression of maximum quantum yield (F_v/F_m), compounded by glutathione pathway inhibition, crippling ROS scavenging. The transcriptome results revealed that C. goreaui prioritizes gene fidelity maintenance under low temperature stress.

Here, we investigated the temperature-dependent (15 °C, 20 °C, 25 °C, and 30 °C) growth rates and paralytic shellfish toxin profiles of eight A. pacificum strains while concurrently examining differences in sequences of the saxitoxin biosynthetic gene, sxtA4. While maximum cell densities were lowest at 30 °C, toxin production per cell was highest at higher temperatures that inhibited growth, with greater diversity of toxin analogs peaking at 30 °C, as confirmed by the higher Shannon's diversity index obtained for the toxin profiles with the increasing temperatures. Furthermore, genetic analysis of the sxtA4 gene showed that greater genetic diversity-quantified by nucleotide diversity (π) ranging from 9.91 to 30.21 across strains-was positively correlated with this wider array of toxin analogs (Shannon's diversity index; p < 0.0001). Conserved regions within the gene were identified, suggesting that these regions may play important structural or functional roles in the saxitoxin biosynthetic pathway. These findings highlight the role of temperature, genetic diversity, and sxtA4 conserved regions in influencing toxin production and profiles in Alexandrium.

We applied eDNA metabarcoding to characterize microbial communities along an anthropogenic pollution gradient in the Magdalena River, a tropical river in Mexico City. Sampling was conducted at four sites representing different levels of human influence. Results revealed differences in both bacterial and microeukaryotic community compositions between sites. In areas with low to moderate disturbance, bacterial genera associated with nitrogen cycling and plant-microbe interactions (e.g., Rhizobacter, Rhodoferax, and Flavobacterium) were predominant, whereas in more heavily impacted sites, genera linked to enteric, nosocomial, or fecal sources (e.g., Arcobacter, Acinetobacter, and Aeromonas) dominated. Peri-urban sites exhibited higher alpha diversity at the phylum level for bacteria, and microeukaryotic communities; two phyla account for over 75% of the relative abundance throughout the year (Ciliophora & Chlorophyta). Statistical analysis showed that water quality influences microbial composition in the sites. These findings demonstrate that urban influence alter microbial community composition, showing similar patterns to other studies.
