Principal component analysis on plant functional traits under the three warming regimes [ambient warming (AM), moderate warming (MW) and severe warming (SW)]. The traits’ loadings on the first two principal components (PCs) are shown, and their projections are sorted by the three warming regimes (A) and the four dominant species (B). Loadings of leaf functional traits (see abbr. list) adjacent to solid symbols are shown. In upper panel (A), blue open, black open, and red open triangles represent AM, MW, and SW, respectively; while the blue, black, and red ellipses indicate the range of each treatment, accordingly. In bottom panel (b), blue open, green open, red open, and yellow open circles represent C. squarrosa (Cs), S. tianschanica (St), N. pectinate (Np), T. terrestris (Tt), respectively; while the blue, green, red, and yellow ellipses indicate the range of each species accordingly
