Bacterial community changes and their responses to nitrogen addition among different alpine grassland types at the eastern edge of Qinghai–Tibetan Plateau

Soil microbes play a fundamental role in maintaining nutrient biogeochemical cycles. To understand the distribution of soil bacterial communities on grassland plateaus, high-throughput sequencing was used to compare bacterial communities in soils from swamp meadows (SM), alpine meadows (AM), alpine steppes (AS), and desert steppes (DS) at the eastern edge of the Qinghai–Tibetan Plateau (QTP) in China. We then compared response to nitrogen...
