Abstract Land-ocean interactions greatly impacted the evolution of coastal life on Earth. However, geological forces and genetic mechanisms that shaped evolutionary adaptations allowed microorganisms to inhabit brackish waters remain largely unexplored.

Subsurface environments are among Earth’s largest habitats for microbial life. Yet, until recently, we lacked adequate data to accurately differentiate between globally distributed marine and terrestrial surface subsurface microbiomes. Here, analyzed 478 archaeal 964 bacterial metabarcoding datasets 147 metagenomes from diverse widely environments. Microbial diversity is similar in microbiomes at local global scales. However, community composition greatly differs sea land, corroborating a phylogenetic divide that mirrors patterns plant animal diversity. In contrast, overlaps supporting continuum rather than discrete biosphere. Differences life thus seem greater land subsurface. Diversity of decreases with depth, while distance cultured isolates rivals or exceeds We identify distinct compositions but

Abstract Estuarine and coastal ecosystems are of high economic ecological importance, owing to their diverse communities the disproportionate role they play in carbon cycling, particularly sequestration. Organisms inhabiting these environments must overcome strong natural fluctuations salinity, nutrients, turbidity as well numerous climate change-induced disturbances such land loss, sea level rise, and, some locations, increasingly severe tropical cyclones that threaten disrupt future ecosystem health. The northern Gulf Mexico (nGoM) along Louisiana coast contains dozens estuaries, including Mississippi-Atchafalaya River outflow, which dramatically influence region due vast upstream watershed. Nevertheless, microbiology estuaries surrounding have received little attention. To improve our understanding microbial ecology understudied nGoM, we conducted a 16S rRNA gene amplicon survey at eight sites multiple timepoints one inland swamp spanning freshwater brackish salinities, totaling 47 duplicated Sterivex (0.2-2.7 µm) prefilter (> 2.7 samples. We cataloged over 13,000 ASVs from common marine clades SAR11 (Alphaproteobacteria), Synechococcus (Cyanobacteria), acI Candidatus Actinomarina (Actinobacteria). observed preferences for or habitats many organisms also characterized group taxa with specialized distributions across water sites, supporting hypothesis an endogenous brackish-water community. Additionally, several aquatic typically considered taxa, subclade II, SAR324, Actinobacteria. data presented here expand geographic coverage estuarine communities, help delineate autochthonous allochthonous members environments, provide critical microbiological baseline nGoM.
