The Asiatic wild ass (Equus hemionus), regionally also known ... -
Hidden treasure of the Gobi: understanding how water limits range use of khulan in the Mongolian Gobi
Payne, John C.; Buuveibaatar, Bayarbaatar; Bowler, Diana Elizabeth; Olson, Kirk A.; Walzer, Chris; Kaczensky, Petra (Peer reviewed; Journal article, 2020)Most large herbivores in arid landscapes need to drink which constrains their movements and makes them vulnerable to disturbance. Asiatic wild ass or khulan (Equus hemionus) were widespread and abundant throughout the arid ... -
