Fig. 3From: Plant composition changes in a small-scale community have a large effect on the performance of an economically important grassland pestOrdination classification of relationships between measures of grasshopper performance and plant stoichiometric characteristics. The arrows indicate the grasshopper performance measures (male mass, male length, female mass, female length) and plant stoichiometric characteristics (C, N, P contents, C:N ratio, C:P ratio, and N:P ratio). X-axis and Y-axis represent the first and second principal components of these variables. Ellipses indicate plant types corresponding to S. krylovii (Sk, blue), L. chinensis (Lc, green), and A. frigida (Af, red)Back to article page
