Genetic characterization and phylogeography of the wild boar Sus scrofa introduced into Uruguay
The European wild boar Sus scrofa was first introduced into Uruguay, in southern South America during the early decades of the last century. Subsequently, and starting from founder populations, its range spread throughout the country and into the neighbouring Brazilian state Rio Grande do Sul. Due t...

The European wild boar Sus scrofa was first introduced into Uruguay, in southern South America during the early decades of the last century.
