Table 1.
Differences in observed mean measures of genetic variability between feline parvovirus (FPV) seronegative and FPV-seropositive raccoons, subdivided by year and age class. Positive values indicate seronegative animals had greater means for the metric of interest. Values in parentheses represent the per cent of 10 000 randomization trials that resulted in mean differences greater than the observed differences. Values in bold represent those greater than expected by chance (α < 0.05).
