Table 2. Summary of results of statistical tests. The interaction numbers refer to corresponding interactions described in Table 1 and depicted in Fig. 2. Only values for variables with statistically significant results (P < 0.05) are reported. For a complete list of statistical tests performed see Tables S1 and S2 in the Supplementary material. G7 and G10 refer to the gallers Baccharopelma dracunculifoliae and Rachiptera limbata, respectively.
