Fine root trait dynamics and their relationships with productivity across grasslands under extreme drought

We experimentally removed 66% of growing season precipitation for four years in meadow, typical, and desert grasslands in northern China and evaluated the effects of multiyear drought on community-weighted means (CWMs) and functional diversity of fine root traits (first-order roots), and their relationships with aboveground net primary productivity (ANPP). Here, we uploaded these root traits, ANPP data and R code.
