Compute pairwise "niche overlap" in geographic space for Maxent predictions. The value ranges from 0 (no overlap) to 1 (identical predictions). The function uses the `nicheOverlap`

function of the dismo package (Hijmans *et al.* 2011).

calc.niche.overlap(predictive.maps, stat = "D", maxent.args)

`predictive.maps` |
A rasterStack of at least 2 Maxent predictive raster layers. |

The statistic calculated by the |

`maxent.args` |
A list of (1) feature classes, and (2) regularization multiplier values that describe model settings for each predictive map provided in |

A matrix with the lower triangle giving values of pairwise "niche overlap" in geographic space. Row and column names are given by the `make.args`

argument when run by the `ENMevaluate`

function.

Based on dismo::`nicheOverlap`

, which is based on SDMTools::`Istat`
