Enhanced precipitation variability decreases grass- and increases shrub-productivity

 

 

Effect of precipitation variability on ANPP through time for: (A) total ANPP, (B) dominant-grass species ANPP, (C) shrub-species ANPP, and (D) rare-species ANPP. Points indicate mean values (±SE, n = 10) for each treatment; and different colors indicate different treatments. Different letters indicate significant differences among treatments within year.
