AbstractAlthough microbial diversity patterns along elevations have been extensively studied, little is known about whether the patterns are influenced by seasonality. To test the seasonal and elevational effects on microbial communities and functions, we collected soil samples across a mountain gradient above and below the treeline in three seasons (spring, summer and autumn). Microbial diversity based on the sequencing of 16S rRNA, 18S rRNA and nifH genes was measured, and microbial functions represented by soil basal respiration and microbial biomass were analyzed. As expected, we found significant seasonal and elevational effects on microbial alpha-and beta-diversity and functions, and the effects of elevations were greater than seasonal effects. Elevational patterns of microbial beta-diversity and functions were not influenced by seasonality. However, the elevational alpha-diversity patterns showed by specific groups (bacteria, protist and metazoa) changed among seasons. Further, we identified key soil properties (i.e. moisture, total carbon, total nitrogen and nitrate) which had higher seasonal and elevational variations, mainly contributing to the spatiotemporal variations of microbial diversity and functions. The findings of higher soil nutrients, archaeal and metazoan richness, and microbial functions at the treeline elevation, imply a strong edge effect of treeline on microbial diversity and functions. Together, our study highlights that seasonality influences the elevational patterns of soil microbial alpha-diversity, rather than that of beta-diversity and functions, thus provides new insights into the seasonal and elevational effects on microbial communities and functions.
