Also, considering that M determines the set of regions and environments occupied by the species, the known set of presence records (G+) occur in geographic space (Go), so the associated environments η(G+) are already reduced by M. As a consequence, niche models that have been calibrated in an M region will frequently under-char- acterize the NF (Peterson and Soberón 2012), and the estimation of their centroid will be biased.	cache/jbi-13218.pdf	txt/jbi-13218.txt
