英文摘要 | the biogeographical distribution of soil bacterial communities has been widely investigated. however, there has been little study of the biogeography of soil archaeal communities on a regional scale. here, using high-throughput sequencing, we characterized the archaeal communities of 94 soil samples across the eastern tibetan plateau. thaumarchaeota was the predominant archael phylum in all the soils, and halobacteria was dominant only in dry soils. archaeal community composition was significantly correlated with soil moisture content and c: n ratio, and archaeal phylotype richness was negatively correlated with soil moisture content (r = -0.47, p < 0.01). spatial distance, a potential measure of the legacy effect of evolutionary and dispersal factors, was less important than measured environmental factors in determining the broad scale archaeal community pattern. these results indicate that soil moisture and c: n ratio are the key factors structuring soil archaeal communities on the eastern tibetan plateau. our findings suggest that archaeal communities have adjusted their distributions rapidly enough to reach range equilibrium in relation to past environmental changes e.g. in water availability and soil nutrient status. this responsiveness may allow better prediction of future responses of soil archaea to environmental change in these sensitive ecosystems. |
