Extended Data Fig. 7: Effect of watering and drought treatments in the McLaughlin Water Experiment on CTI (°C) and CPI (mm).
From: Rapid shifts in grassland communities driven by climate change
Watering experiments were conducted in both (A) serpentine and (B) non-serpentine sites, while drought experiment was conducted in (C) the serpentine site. Ambient plots, watering plots, and drought plots are in black, blue, and brown, respectively. There were 30 ambient and 30 treatment plots in (A). There were ten ambient and ten treatment plots in (B) and (C). Effects across all years were estimated by linear mixed-effects models (two-sided t-test; ns: p > 0.05, * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001). Box plots show the median (center), the first and third quartiles (bounds of the box), the range extending to the smallest and largest values within 1.5 times the interquartile range from the first and third quartiles (whiskers), and outliers beyond this range (points).
