Fig. 4From: Plant composition changes in a small-scale community have a large effect on the performance of an economically important grassland pestAssociation between grasshopper performance and plant stoichiometric characteristics. X-axis and Y-axis indicate the first two ordination scores of grasshopper performance variables. The convex hulls (red) enclose centroids of grasshopper performance measures obtained from grasshoppers fed with the corresponding plants, S. krylovii (Sk), L. chinensis (Lc), and A. frigida (Af). The ellipses enclose confidence areas (95%) of grasshopper performance measures. The blue arrows indicate the plant stoichiometric characteristics for three plantsBack to article page
