  "abstract": "IntroductionBacterial community composition differed markedly among substrates, whereas broad community-level differences between sampling localities were not statistically detected. The recovered U. aurantiacoatra bacterial community was dominated by Pseudomonadota, while A. regularis and soil communities exhibited greater taxonomic diversity, with Pseudomonadota, Actinomycetota, and Cyanobacteriota as dominant phyla. Functional profiling revealed distinct metabolic patterns across microhabitats. Bulk soils exhibited the broadest metabolic potential and nearly complete nitrogen-cycling pathways. The A. regularis microbiome was enriched in autotrophic machinery, high-affinity transport systems, and environmental sensing pathways, whereas the lichen microbiome displayed a more streamlined functional profile, lacking diagnostic nitrogenase genes and dissimilatory pathways.DiscussionThese findings highlight the importance of substrate identity in structuring bacterial communities across adjacent Antarctic microhabitats. The observed differences in taxonomic composition and functional potential suggest that mosses, lichens, and soils provide distinct ecological niches, potentially influencing microbial contributions to nutrient cycling in Antarctic terrestrial ecosystems.",
