Contrasting early successional dynamics of bacterial and fungal communities in recently deglaciated soils of the maritime Antarctic
Abstract 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 bacteri...

Abstract 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‐favouring taxa) contributed greatly to bacterial beta diversity, but this pattern was less clear in fungi.
