Abstract

Over the last two decades wild boar Sus scrofa Linnaeus, 1758 became the most intensively managed game species in Bulgaria. In order to delineate the population genetic structure, which is essential for sustainable wildlife management, we screened 10 porcine microsatellites across 289 wild boar samples originating from all relevant bioregions of the country. Results based on F ST values, Bayesian clustering methods and a multi-dimensional scaling analysis can be summarised as follows: (1) two main genetic groups were revealed for the Bulgarian data set: the first one included individuals collected from the Balkan Range Mountain and the northern part of the country and the second one comprised individuals from the Rhodope, Osogovo, Iskur Range and Rila mountains in southern and south-western Bulgaria; (2) all Bulgarian wild boar populations showed a higher level of genetic diversity compared to four populations from Germany which were included for outgroup comparison, and (3) wild boar sampled from a game enclosure were found to be genetically divergent from the other Bulgarian populations, indicating human impact on population genetic structure most likely resulted from fencing and former translocation actions. The evolutionary background leading to the two defined management units as well as conservation and management strategies are discussed.
