Changes in the microbial community structure of bacteria, archaea and fungi in response to elevated CO2 and warming in an Australian native grassland soil

The microbial community structure of bacteria, archaea and fungi is described in an Australian native grassland soil after more than 5 years exposure to different atmospheric CO2 concentrations ([CO2]) (ambient, +?550?ppm) and temperatures (ambient, +?2 degrees C) under different plant functional types (C 3 and C 4 grasses) and at two soil depths (05?cm and 510?cm). Archaeal community diversity was influenced by elevated [CO2], while under warming archaeal 16S rRNA gene copy numbers increased for C 4 plant Themeda triandra and decreased for the C 3 plant community (P?
