Results of PCAs and the co-inertia analyses. For each transect are given the percentage of variance explained by the first two axes of the PCAs applied to orthoptera and nematode abundance matrices and RV coefficients of the co-inertia analyses performed on PCA

The co-inertia analyses indicated a partial decoupling between above- and below-ground herbivore abundance matrices suggesting that the surface climatic conditions might be buffered belowground where edaphic factors govern to shape soil communities
