Sus scrofa is one of the most widespread mammal species and it isheavily managed throughout its range in both its domestic andwild form. The wild boar is one of the most relevant game speciesin Europe but it is also considered a pest as it can produceeconomically important crop damages. Hybridization with thedomestic pig is known to occur in Europe, however the degree andextent of the phenomenon is not fully understood yet.Introgression is considered to be a treat to biodiversity and couldlead to loss of local adaptation or introgression in the wildpopulation of human selected genes. A better understanding of thehybridization levels at European scale would provide an importanttool for the development of management plans aimed at reducinghuman conflict but also at preserving biodiversity and geneticdifferentiation. Additionally, this information would provide newperspectives on infection routes for pig diseases and zoonoses.Here we report the first results of an ongoing study using genomewide SNPs data. Concordantly with previous studies we foundvariable levels of introgression from non-detectable to quite highaccording to sampling location. Interestingly, we also observedgradients in variability levels among the analysed wild anddomestic populations. This preliminary results will be furtherinvestigated to address the possible presence of hybrid zone(s) inEurope and the possible implications for conservation andmanagement of both wild populations and local pig breeds, as wellas the development of contingency plans for infectious pigdiseases
