Table 2 Results of the niche similarity and equivalency tests for the reproductive period. Below the diagonal, pair-wise niche similarity (D_obs) scores are given and asterisks indicate a significant two-tailed niche similary test (* p < 0.05; in the significant pair, D_obs was higher than expected by chance). Above the diagonal, significances of pair-wise equivalency tests are shown (* p ≤ 0.05, ** p ≤ 0.01, NS: not significant; in all significant pairs, D_obs was lower than expected by chance)
