Microsatellite diversity and population structure of the wild boar in Croatia

Over the last decades the wild boar (Sus scrofa, L.) population experienced a true biological expansion that followed the trend prevalent in all of Europe. Here we analyzed the genetic structure and microsatellite biodiversity of the population of wild boars (260 animals) collected from 16 different locations during organized legal drive hunts. We have also analyzed the genetic structure of 25 domestic pigs as an out-group cluster. Individuals were genotyped for 14 microsatellite loci (S0002, S0005, S0026, S0090, S0097, S0155, S0226, SW122, SW240, SW632, SW857, SW911, SW936, and SW951). At the first level, the Bayesian methods implemented in STRUCTURE program were discriminated into three clusters, one with domestic pigs and two wild boar clusters (Northern versus Southern). At the second level, both, Northern and Southern clusters were further separated into two clusters each. The mean pair-wise FST values were much lower between the Northern clusters and domestic pig cluster (FST = 0.161) than between the Southern clusters and domestic pig cluster (FST = 0.261), while the pair-wise FST between Northern and Southern clusters was equal to 0.092. The classification and admixture pattern observed was geographically dependent. The phenotypic appearance (white coat color and large number of teethes) of some wild boars indicated hybridization between wild boars and domestic pigs. However, the estimated proportion of domestic pigs based on microsatellite information was negligible (up to a few percent). The results presented will be used in management programs of wild boars in Croatia.
