Mitochondrial DNA diversity of feral pigs from Karukinka Natural Park, Tierra del Fuego Island, Chile

Genetic diversity and phylogenetic relationships in feral pig populations from Argentina

“…Previous studies on genetic diversity making use of the CR marker in feral pig populations in Chile and Brazil, showed European ascendancy on all individuals studied (Aravena et al, 2015;Grossi et al, 2006). On the other hand, there is evidence that feral pig populations from Tierra del Fuego (Chile) are more recent than the Argentinian populations, being established over the XIX century (Aravena et al, 2015;Gade, 1987). In our study, feral pigs from Tierra del Fuego presented haplotypes (H28 and H29) related to the ones from Corrientes (H17 and H5), and showing haplotype identity with Iberian breeds as well.…”

“…In our study, feral pigs from Tierra del Fuego presented haplotypes (H28 and H29) related to the ones from Corrientes (H17 and H5), and showing haplotype identity with Iberian breeds as well. The genetic closeness between this geographically distant feral populations, may be ought to the scarce or absent intervention of other morphotypes, entailing to a gene pool nearly identical to that of Iberian breeds (Aravena et al, 2015;Gade, 1987).…”

“…Before our research the only records in South America, as to genetic diversity in feral pig populations, are from the studies of Aravena et al (2015) and Grossi et al (2006), for populations from Tierra del Fuego (Chile) and Pantanal (Brazil), respectively.…”

“…Nowadays, the advance of molecular techniques coupled with phylogenetic analysis for Sus scrofa, using the control region (CR) of mitochondrial DNA and the Y chromosome marker, are key to unravel the history of the introduction of wild populations, variability levels and population structure (Aravena et al, 2015;Gongora et al, 2004;Iacolina et al, 2016;Kim et al, 2002;Larson et al, 2010;Ramírez et al, 2009;Scandura et al, 2008;Veličkovi ć et al, 2015). Particularly the use of CR sequences, have allowed the identification of the geographic distribution for the different clades: E1 (widely distributed in the European continent), subdivided in E1-A (Italy, France, Germany, and Austria), and E1-C (Iberian Peninsula and Central Europe), E2 (restricted to Italian Peninsula, Sardinia and Croatia), NE (Near Eastern) and A (Asian) (Alexandri et al, 2012;Fang and Andersson, 2006;Giuffra et al, 2000;Kusza et al, 2014;Ramírez et al, 2009).…”
