Study population over time. In the time-period shown here, the population rose and fell cyclically until 1994, when it plummeted due to the high-mortality CDV epidemic shown in grey; in 1999 the population returned to previous levels (Packer et al., 2005). The black bar indicates the time period from 1984 through 1995 when samples were assessed for FIVPle subtype distribution. The three dark grey bars (above the back bar) represent periods of high intensity sampling.
