n forest ecosystems, trees represent the major primary producers and affect the chemical composition and microbial processes in the ecosystem via specific litter chemistry and rhizodeposition. Effects of trees on the abundance of soil microorganisms have been previously observed but the extent to which trees affect the composition of microbial communities remains unknown. Here we analyse the factors affecting the composition of bacterial and fungal communities in forest litter and soil under seven tree species studied at twenty-eight spatially independent sites of similar age developed on the same initial substrate. Microbial communities differed between litter and soil. Bacterial communities were more diverse than fungal communities, especially in litter, and exhibited higher evenness. Eighty percent of the bacterial sequences belonged to the 200-250 most dominant operational taxonomic units (OTUs), and 80% of the fungal sequences were composed of only 23-28 OTUs.
