Predicting geographic distribution and habitat suitability of in paleoclimatic, current, and future scenarios in Mexico.

Mexican territory is one of the centers of origin and dispersion of the genus , where several of its species have been an important plant resource for people in arid and semiarid zones. is widely distributed in Mexico; however, precise aspects of its geographic distribution and ecological status are still unknown. Here, we modeled its potential distribution under paleoclimatic, current, and future conditions through maximum entropy and predictions from 824 records and seven environmental variables.
