Abstract in EnglishBiological soil crusts (biocrusts) provide key ecosystem services in dryland ecosystems, especially soil fertility and surface stability. The relationships between soil fertility and microbial communities have been demonstrated with successional stages of biocrusts, however, the effects of soil stability on microbial communities are poorly understood. Thus, we investigated the changes in microbial communities, soil stability and fertility with biocrust succession and sampled soils with biocrusts with increasing moss coverage in a semiarid climate in the Loess Plateau of China. The phospholipid fatty acid (PLFA) method was used to determine the structural diversity of the microbial groups. The results showed that soil cohesion (which represented the soil stability) increased by 40%, and that the content of organic matter, total N and available N was 93%, 8% and 1.9 times greater in the later successional moss than in the early successional cyanobacteria. Consequently, the microbial diversity according to the Shannon and Simpson indices increased by 1.80% and 0.44%, respectively, and the microbial biomass was 3.1 times higher in the moss biocrusts than in the cyanobacteria biocrusts in biocrust layer, and the underlying 0-2 cm soil layer showed the similar changes of soil properties and microbial communities with biocrust layer. These findings are important for achieving a better understanding of the functions and services of biocrusts and provide a prediction for ecosystem processes in dryland ecosystems.
