Non-linear Responses of Soil Diazotrophs to Aridity in Xinjiang Grasslands

资源简介：
Although drought is known to strongly influence soil microbial structure and ecosystem functioning, it remains unclear how diazotrophic communities respond to drought gradients. We investigated diazotrophs across 155 grassland sites spanning a wide aridity gradient in Xinjiang, China (1−AI: 0.46–0.88), integrating structural equation modeling, null model analysis, and co-occurrence network analysis to identify critical thresholds and elucidate community assembly mechanisms of diazotrophs under drought
