Niche comparison metrics as calculated in ENMtools.

Here the range overlap (difference in ranges between time periods), relative rank overlap (difference in habitat pairing between time periods), and niche overlap (I) (pairwise niche overlap between time points) metrics are shown. The results (significance or non-significance) of the identity test are also given for each applicable comparison (Relative Rank and Niche Overlap). Due to the nature of the identity test we could only compare point distributions under either the current or the future climate model, as such only two comparisons per model were conducted. Significance of the identity test (p0.05) is indicated by “n.s.”. The analysis indicates highly divergent Historic and Contemporary (current and projected) distributions of O. continuatalis.
