The pos­si­bil­ity that preda­tors choose prey selec­tively based on age or con­di­tion has been sug­gested but rarely tested. Researchers from Col­orado and Utah State Uni­ver­si­ties exam­ined whether moun­tain lions (Puma con­color) selec­tively prey upon mule deer (Odocoileus hemionus) infected with chronic wast­ing dis­ease, a prion dis­ease. They com­pared dis­ease preva­lence among lion-​killed adult (≥2 years old) deer with preva­lence among deer taken by hunters in the vicin­ity of the moun­tain lion kill sites. The sur­vey sug­gest that moun­tain lions in this area actively selected prion-​infected indi­vid­u­als when tar­get­ing adult mule deer as prey items.
