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

Cím:The use of museum skins for genomic analyses of temporal genetic diversity in wild species / Astrid Vik Stronen, Laura Iacolina, Cino Pertoldi, Szilvia Kusza, Pavel Hulva, Ihor Dykyy, Ilpo Kojola, Søren Faurby

Megjegyzések:Analyses of museum specimens can help illuminate temporal changes in wildlife genetics and distributions, and the objective of our study was to evaluate the suitability of skin samples from the past century for genomic analyses. We examined two European species with extensive genomic resources and existing data: the wild boar (Sus scrofa) and the wolf (Canis lupus). Populations of both species declined during the twentieth century, followed by a strong recovery. Moreover, Carpathian Mountain wolves are genetically divergent from Northern European lowland wolves, and their evolutionary history is incompletely understood. We analysed genetic variation from skins of 14 European and Near Eastern wild boars (1903-1948) and 18 Carpathian and Northern wolves (1938-1998). Samples were genotyped in duplicates with standard Illumina single nucleotide polymorphism (SNP) arrays (wild boar 60 K and wolves 170 K), and we retained SNPs with a genotyping rate of >90%. We obtained a final set of 1595 SNPs for six wild boars (genotyping rate 0.99) and 1806 SNPs for 18 wolves (genotyping rate 0.96). We merged the best performing duplicate with modern data and calculated polymorphism (P), observed (HO) and expected (HE) heterozygosity per population. Our findings underline the difficulties in obtaining quality genomic profiles from museum skins, though a limited number of SNPs provided insights for future research. Wild boars exhibited lower polymorphism in historical than modern samples. In contrast, patterns in wolves appeared spatial rather than temporal, with higher P, HO and HE observed in Carpathian than Northern wolves across historical and modern samples.
