| 摘要 | Purpose Global climate change, in particular temperature variation, is likely to alter soil microbial abundance and composition, with consequent impacts on soil biogeochemical cycling and ecosystem functioning. However, responses of belowground nitrogen transformation microorganisms to temperature changes in high-elevation terrestrial ecosystems are not well understood. Materials and methods Here, the effects of simulated cooling and warming on the abundance and community composition of ammonia-oxidizing archaea (AOA) and bacteria (AOB), as well as the abundance of denitrifiers, were investigated using quantitative polymerase chain reaction and clone library approaches, on the basis of a 2-year reciprocal elevation translocation experiment along an elevation gradient from 3,200 to 3,800 m above sea level on the Tibetan Plateau. Results and discussion We found that, compared with the temperature variations caused by elevation translocation, the soil origin exerted a much stronger influence on AOA abundance. There were significant effects of both soil origin and elevation translocation on AOB abundance, which was particularly decreased by elevation-enhanced (simulated cooling) and increased by elevation-decreased (simulated warming) treatments. Altered temperature affected the abundance of nirK rather than nirS and nosZ genes, and the latter two seemed to be associated tightly with the soil origin. Furthermore, the results showed that temperature changes had obvious influences on the community structure and diversity of AOB, but not AOA. More apparent response of AOB to warming than in other studies on grassland and forest ecosystems may be attributed to higher elevation and lower mean annual temperature in this study. Conclusions Our findings thus suggest that, in comparison with AOA and denitrifying populations, AOB may respond more sensitively to natural temperature variation caused by elevation translocation in this alpine grassland ecosystem on the Tibetan Plateau.; Purpose Global climate change, in particular temperature variation, is likely to alter soil microbial abundance and composition, with consequent impacts on soil biogeochemical cycling and ecosystem functioning. However, responses of belowground nitrogen transformation microorganisms to temperature changes in high-elevation terrestrial ecosystems are not well understood. |
