Large-scale chlorophyll investigations will be useful for developing prediction techniques. The results implied that warming might drive shifts in grassland chlorophyll distribution mainly by alternations in species composition. At the regional level, the chlorophyll concentration and composition depend on the limitations of the local climate or resources. Compared to chlorophyll concentration, chlorophyll composition was more conservative, with a slight shift in distribution. Still, their distributions shifted in opposite manners: chlorophyll concentration was distributed in a broader but more differential manner, while chlorophyll composition was distributed in a narrower but more uniform manner. The results showed that the means of chlorophyll concentration and composition (chlorophyll a/ b) increased with the mean annual temperature. In the three plateaus, variations and distributions of species chlorophyll concentration and composition were compared. Three grassland transects with a natural temperature gradient were designed in the Tibetan, Mongolian, and Loess Plateau to describe the changes in chlorophyll under different warming scenarios for 475 species. However, chlorophyll adaptations-good representative of plant production-in grasslands have not been investigated on a large scale, hindering ecological predictions of climate change. Global warming has significantly altered the distribution and productivity of vegetation owing to shifts in plant functional traits.
