Table 3.

Results of the permutation tests for evaluating the significance of each of the variables included in the explanatory matrix in the redundancy analysis (RDA) (F and P) and in partial RDAs (F_p and P_p), and the proportion of variance explained by each variable when controlling for the remaining variables in partial RDAs (R²_adj). RW, ring width; MAT, mean annual temperature; MD_s, summer moisture deficit index.
