Older pumas and female Florida panthers at higher risk of feline foamy virus (FFV) infection. (A) The plot displays variable importance weights for puma sex or age as risk factors for FFV, showing age to be more important in Colorado, Southern California and across the sampling locations (overall). (B) The plot displays model averaged coefficients with 95% confidence intervals, with adult and male being >0, and young and female being <0. If the 95% confidence interval did not cross 0, the variable was considered important. Females were weakly associated with infection risk in Florida only.
