Abstract: Study of the climate variability in the past and present, and correlating those with changes in the distribution range of critically endangered and vulnerable species has attracted considerable research interest. The genus Neurergus consists of five recognized species, of which N. crocatus, N. derjugini, N. kaiseri, and N. microspilotus are documented from Iran. In the present study, we modeled with MaxEnt the potential distribution areas and determined the suitable habitats in the past (mid-Holocene [MH], and the Last Interglacial [LIG]) as well as the current distribution of the vulnerable Lorestan Mountain newt, N. kaiseri. Models of the species indicated good fit by the average high area under the curve (AUC) values (0.998 ± 0.001). The annual temperature range, topography, slope as well as annual precipitation made important contributions to current distribution N. kaiseri. We conclude that these variables form a natural barrier for species dispersal. The MH and the LGM models indicated a larger suitable area than the current distribution. The precipitation of coldest, driest and warmest quarter of the year as well as annual temperature range made important contributions to the mid-Holocene [MH], and the Last Interglacial [LIG]) distribution in N. kaiseri.
