Tóm tắt

 Understanding how plant functional traits respond to nutrient enrichment becomes more crucial for predicting changes in grassland community composition and functions under global changes. However, it remains unclear how nitrogen (N) and phosphorus (P) additions jointly influence a variety of leaf traits and how they coordinate with contrastingly adaptive mechanisms in arid ecosystems. A two-year field experiment with five N levels and two P treatments was conducted to examine the effects of N and P additions on leaf/community functional traits in a desert steppe. We found N addition significantly affected the other six leaf morphological and nutrient traits except leaf thickness (LT)
  nitrogen addition remarkably increased leaf nitrogen concentration (N
