Genetic analysis to assess the geographic scale of feral pig population structure

The overall objective of this study was to examine the population genetic structure of feral pigs in far north Queensland. Feral pig tail and ear tissue samples (N = 328) were obtained from 28 locations (Table S1) between Tully and Innisfail in far north Queensland, Australia (Fig. 1). Demographic data including gender and weight were recorded. The samples were stored in 100% ethanol at -20°C until DNA extraction. Figure 1 shows the proportion of individuals at each site with ancestry to each of the three inferred groups (beige, grey and black) based on Bayesian clustering analysis and positioned on a map of the study area.
