Although microorganisms are the very first colonizers of recently deglaciated soils even prior to plant colonization, the drivers and patterns of microbial community succession at early-successional stages remain poorly understood. The successional dynamics and assembly processes of bacterial and fungal communities were compared on a glacier foreland in the maritime Antarctic across the ~10-year soil-age gradient from bare soil to sparsely vegetated area. Bacterial communities shifted more rapidly than fungal communities in response to glacial retreat; species turnover (primarily the transition from glacier- to soil-favoring taxa) contributed greatly to bacterial beta diversity, but this pattern was less clear in fungi. Bacterial communities underwent more predictable (more deterministic) changes along the soil-age gradient, with compositional changes paralleling the direction of changes in soil physicochemical properties following deglaciation. In contrast, the compositional shift in fungal communities was ... : Supplementary Table.S1-S2.xlsx : Metadata consists of soil physicochemical properties and a summary of the sequencing result for bacterial and fungal communities of glacier foreland in Potter Cove on King George Island. potter.bac.comm.txt : Bacterial(16S V4 region) ASV table potter.fun.comm.txt : Fungal(ITS2 region) ASV table ...
