TL;DR: A comprehensive analysis of soil bacterial community composition and diversity along six elevations representing six typical vegetation types from forest to alpine tundra using a bar-coded pyrosequencing technique suggests that pH is a better predictor of soilacterial elevational distribution and also suggests that vegetation types may indirectly affect soil bacterial Elevational distribution through altering soil C and N status.

TL;DR: It is shown that arctic soil bacterial community composition and diversity are structured according to local variation in soil pH rather than geographical proximity to neighboring sites, suggesting that local environmental heterogeneity is far more important than dispersal limitation in determining community-level differences.

TL;DR: The data implicate the role of livestock manures in preventing the loss of bacterial diversity during long-term chemical fertilization, and highlight pH as the major deterministic factor for soil bacterial community structure.

TL;DR: It is shown that pH is the best predictor of bacterial community structure in alkaline sediments, and that both geographic distance and chemical factors govern bacterial biogeography in lake sediments.

TL;DR: In this article, the responses of soil bacterial diversity to N enrichment were investigated at surface (0-10 cm) and sub-surface (10-20 cm) soils in a temperate steppe ecosystem.
