DATA form Functional trait space expansion explains productivity gains under moderate grazing

File descriptionsdatasheet1_productivity&hypervolume at community and species level:Changes in productivity and cwm_hypervolume of each plot under four grazing intensities. And at species level, its biomass and volume of each plot under four grazing intensities.datasheet2_scaled trait&rfresult:Changes in scaled trait (mean=0 and SD=1) of plant community and three response groups under four grazing intensities. And relative importance of each trait in determining community trait space was assessed from Random Forest Model. And the community weighted mean of all traits and productivity of each plot.datasheet3_11species photosynthesis:Changes in net assimilation rate of 11 representative composing species (i.e., three species for each of legumes, forbs and graminoid).treat=NG: no grazing; treat=L: light grazing intensity; treat=M: moderate grazing intensity; treat=H: heavy grazing intensity.
