To test the hypothesis that dominant plant species could acquire different nitrogen (N) forms over a spatial scale and they also have the ability to compete for available N with microbes. A short-term 15N labeling experiment was conducted in the temperate grassland ecosystem of North China in July of 2013. Three N forms (NO3 − , NH4 + and glycine) labeled(More)
Leymus chinensis and Stipa grandis are two important plant species of temperate steppes in Inner Mongolia of North China. They differ in their life forms, e.g., L. chinensis is a type of rhizomatous clonal grass, whereas S. grandis is a type of tussock grass.
