Temporal distribution of dietary exposure of three captive mountain lions (Puma concolor) to carcass materials from native cervids infected with chronic wasting disease (CWD). Bar segments show the cumulative number of CWD-positive (solid) and negative (open) feeding opportunities within successive 12-mo periods, as summarized from available feeding records and observed behavior assuming all three animals partook in each feeding opportunity. Study years defined as May–April (e.g., year 1 May 2002–April 2003). Asterisk (*) indicates study years that had ≥1 mo of missing feed records (late June to early August 2004; early March 2014 to late July 2015).
