Actinobacteria community structure in the peat profile of boreal bogs follows a variation in the microtopographical gradient similar to vegetation

摘要: Boreal mires are globally important carbon stores. In nutrient poor mires, i.e. bogs, vegetation is highly structured between hydrologically different microforms: hummocks, lawns and hollows. We studied whether the structure in four boreal bogs reflected actinobacterial decomposer communities. Vegetation was determined by projection cover of plant species. Actinobacteria were detected from peat profiles at depths 0–20, 20–40 40–60 cm molecular methods. The data analysed a hierarchical set ordinations. inter-bog variation communities insignificant, while intra-bog differences (microforms) each bog significant. This actinobacteria two upper layers. deepest layer (40–60 cm) showed some differences, possibly due to history bogs. Our results show that reflect vegetation, which turn tied hydrological conditions. possible alterations water level caused changing climate likely cause predictable changes microbial ecosystems.
