Effects of Climate Change on Habitat Suitability and Distribution Model of the Critically Endangered Newt, Neurergus Derjugini Nesterov, 1916 (Urodela: Salamandridae) from Contemporary Period to 2030 (original) (raw)

2021, Taxonomy and Biosystematics

Evaluating the role of climate changes on species distributions has attracted considerable research interest. The Kurdistan newt (Neurergus derjugini) is one of the critically endangered species in the IUCN Red List, which is distributed in the Avroman Mountains in Iran, on the Iraqi-Turkish border. Nowadays, the population of this species is declining and under serious threat due to several factors, including climate change. In the present study, by using the maximum entropy approach (MaxEnt), based on bioclimatic (precipitation and temperature) and topographical (altitude and slope) variables, the suitable habitats and the potential distribution areas in the contemporary and the representative concentration pathway (RCP) 2.6 scenario and RCP 8.5 scenarios of the future (2030) distribution were modeled for the Kurdistan newt, N. derjugini. Precipitation of the coldest quarter (38.8%), slope (26.8%) and temperature annual range of the year 13.6%) were the most important factors shap...
