Elevated CO₂ and Warming Altered Grassland Microbial Communities in Soil Top-Layers.

ABSTRACT: As two central issues of global climate change, the continuous increase of both atmospheric CO₂ concentrations and global temperature has profound effects on various terrestrial ecosystems. Microbial communities play pivotal roles in these ecosystems by responding to environmental changes through regulation of soil biogeochemical processes. However, little is known about the effect of elevated CO₂ (eCO₂) and global warming on soil microbial communities, especially in semiarid zones. We used a functional gene array (GeoChip 3.0) to measure the functional gene composition, structure, and metabolic potential of soil microbial communities under warming, eCO₂, and eCO₂ + warming conditions in a semiarid grassland. The results showed that th
