Abstract: Data and R code is used to run the anylysis for figure 1-4. This is the last version. If more infomration is needed, please contact Daijun Liu ([email protected]/[email protected]) ##Firstly run the papackages and then library. ##Data is the data meand and site information used in this study. Data relating to shrubland abundance and cover, species diversity, composition and functions were extracted from the studies. Metrics of community-level vegetation responses comprised aboveground biomass (AGB), aboveground net primary production (ANPP), vegetation cover (COV), community density or abundance (DEN), species richness (SP) and species diversity (Shannon diversity index, H). Shrub ratio (Ratio_S) was calculated as the proportion of the aboveground biomass, density or cover of the shrub species relative to the values for the entire community (shrubs and herbs) within a plot. Data of mean values, standard deviations and sample sizes (number of plot replications) of the above-mentioned vegetation metrics in treatments and control were compiled in our meta-analysis. Each study used only one mean value and standard deviation. If a study provided multiple data points during the study period, the mean values and standard deviations were calculated. The magnitudes of net-changes in climate (e.g., warming, increased precipitation and drought) and nitrogen addition in field experiments were also compiled to quantify the vegetation responses. For experimental warming, year and growing season data were collected separately and then the magnitudes of climate and nitrogen addition were compiled. Experiment duration was categorised as short-term (1–5 years) and long-term (>5 years) (Kröel-Dulay et al., 2015).
