The effect of climate change on the distribution and habitat suitability of the critically endangered newt, Neurergus derjugini Nesterov, ۱۹۱۶ (Urodela: Salamandridae): from the contemporary period to ۲۰۳۰

Study of the climate variability in the past and present, and correlating those with changes in the distribution range of critically endangered species has attracted considerable research interest. The genus Neurergus consists of four recognized species, of which Azarbaijan newt N. crocatus, Kurdistan newt N. derjugini, Lorestan newt N. kaiseri are documented from Iran. In the present study, based on bioclimatic and topographical variables modeled and evaluated the suitable habitats and the potential distribution areas in the contemporary as well as the decade future (۲۰۳۰) distribution of the critically endangered newt, N. derjugini Nesterov, ۱۹۱۶ with MaxEnt approach .The results of the models showed precipitation of the coldest quarter of the year, precipitation and temperature seasonality, temperature annual range of the year, and slope made important contributions to the contemporary, as well as precipitation of coldest quarter, precipitation and temperature seasonality of the year variables constructed important contributions to the decade future (۲۰۳۰) of N. derjugini. It can be conclude that these variables form a natural barrier for species dispersal in each specific period.
