The phyllosphere microbiome of aquatic macrophytes constitutes an integral component freshwater ecosystems, serving crucial functions in global biogeochemical cycling and anthropogenic pollutant remediation. In this study, we examined the assembly mechanisms epiphytic bacterial communities across four phylogenetically diverse macrophyte species (Scirpus validus, Hippuris vulgaris, Nymphoides peltatum, Myriophyllum spicatum) inhabiting Ningwu Mayinghai Lake (38.87° N, 112.20° E), a vulnerable subalpine system Shanxi Province, China. Through 16S rRNA amplicon sequencing, demonstrate marked phyllospheric divergence, as follows: Gammaproteobacteria dominated S. H. vulgaris N. while Alphaproteobacteria M. spicatum. nitrate, nitrite, pH value water bodies chlorophyll, leaf nitrogen, carbon contents plant leaves are main driving forces affecting changes β-diversity species. partitioning processes revealed that deterministic dominance governed validus spicatum, where niche-based selection contributed 67.5% 100% to community assembly, respectively. Conversely, stochastic explained variability peltatum microbiomes, predominantly mediated by dispersal limitation ecological drift. This investigation advances understanding microbial structural dynamics diversity stabilization strategies macrophyte-associated establishing conceptual frameworks between plant–microbe symbiosis homeostasis within ecosystems. empirical references derived from these findings offer novel perspectives for developing conservation aimed at sustaining biodiversity equilibrium high-altitude lake habitats, particularly climatically sensitive regions north-central

The maternal microbiome is increasingly being recognized as a key determinant in various neonatal health outcomes, including offspring immunity, metabolism, brain function, and behavior. While the oral, vaginal, skin, gut microbiota are significant contributors to offspring’s postnatal microbial seeding, composition diversity of during pregnancy seems be critical shaping even prior birth. Growing evidence suggests that balance among groups their interactions with host crucial for health. Dysbiotic communities early life may lead disease processes offspring, though specific by which microbes affect development unknown. Here, we summarize research examining shifts pregnancy, effects on infant outcomes. We also discuss current theories how gastrointestinal (GI) tract influences probiotics perinatal period
