Extended Data Fig. 3: Climate change at the observational sites.
From: Rapid shifts in grassland communities driven by climate change
Mean annual temperature (°C) and annual precipitation (mm) are extracted from the CHELSA monthly time series from 1980 to 2019, highlighting the sampling periods in the observational periods for comparison with Fig. 2. Trends are summarized by regression lines, solid p ≤ 0.05, dashed p > 0.05 (two-sided t-test; ns: p > 0.05, * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001). The map shows the geographical distribution of the 12 sites with grassland percent cover (green) from MODIS land cover type data.
