Cím:Barrier effect of the M3 highway in Hungary on the genetic diversity of wild boar (Sus scrofa) population / Bendegúz Mihalik, Viktor Stéger, Krisztián Frank, László Szendrei, Szilvia Kusza

Megjegyzések:Highways are human-related barriers with multiple impacts on the environment. They reduce the habitat of the animals and plants, isolating parts of extant populations from each other and blocking migration routes. They also have a disturbing effect and increase mortality by animals being hit by vehicles. In Hungary, the M3 highway is one of the busiest motorways. In our hypothesis, it acts as a weak to medium barrier to gene flow between the populations on the two sides. To test this hypothesis and to establish the genetic profiles of the wild boars 40 samples (blood, meat, fur or hide) were collected from each side from which genomic DNA was isolated. 13 tetrameric STR markers described in pigs were used for genotyping. Genetic diversity indices and structure were calculated with STRUCTURE v.2.3.4, PAST v.2.17c, Cervus v.3.0.6 and ARLEQUIN v.3 software. The results show that the populations on the two sides of M3 have only minor differences in allele frequencies and heterozygosity values. Nei's and Fst distance values were both negligible (0.045 and 0.025 respectively), which means that the two groups are only slightly separated and still belong to the same population. This situation may be due to the recent building of M3, which started only 40 years ago, or to the functioning wildlife underpasses and the good mobility of wild boars. However, there exists a small effect, which can be intensified in time, therefore periodic monitoring is necessary to prevent stronger isolation.
