摘要: After a strong demographic decline before World War II, wild boar populations are expanding and the species is now second-most abundant ungulate in Europe. This increase raises concerns due to impact on crops natural ecosystems as potential vector of diseases. Additionally, can hybridize with domestic pigs, which could health risks alter adaptive potential. We analysed 47,148 Single Nucleotide Polymorphisms from Europe (292) Near East (16), commercial (44) local (255) pig breeds, discern patterns hybridization across identified 33 boars more than 10% ancestry their genome, mostly concentrated Austria, Bosnia Herzegovina, Bulgaria Serbia. difference probably contrasting practices, free-ranging vs. industrial farming but samples would be needed investigate larger geographic patterns. Our results suggest has occurred over long period still ongoing, we observed recent hybrids. Although have maintained genetic distinctiveness, threats raise require implementation management actions practices aimed at reducing contact between pigs.
