    • 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, 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 ...
