Niche overlap values (D and I), calculated with ENMtools, are given for species pairs and are mostly lower than the randomized overlap levels generated in the identity test at significant (*, p ≤ 0.05, Bonferroni corrected) or highly significant (**, p ≤ 0.001, Bonferroni corrected) level. This means that niches are more divergent than expected at random. In some cases, results are not significant, or significantly higher than the randomized overlap (indicated by

). In these cases, niches are not more divergent than expected by random. Note that results yielded by D and I do not accord in all cases.
