Abstract [en]

Standardized, unbiased and full data on the population diversity and structure of endangered species is one of the most essential needs of conservation biology, as it gives the possibility to effectively manage the species across its distribution range. The present study is, so far, the first one focusing on the neutral and adaptive genetic diversity of Ukrainian populations of Black grouse (Tetrao tetix). It is aimed to fill in the gap in the data on the diversity of European populations of this species. The specific goals of this study are: (1) to estimate both neutral (microsatellite) and adaptive (MHC) diversity of the Northern and the Carpathian Black grouse populations, (2) to infer the population structure of Ukrainian Black grouse, (3) to study the population history of this species, (4) to compare Ukrainian populations with the European ones and estimate the rate of differentiation between them, (5) to draw conclusions about the possible management efforts of the Black grouse on the territory of Ukraine and make suggestions about the subsequent research of this species.The results illustrate that Ukrainian populations are more diverse than the European ones and highly differentiated from them. Both studied populations did not show any signs of a recent bottleneck event. Population structure of Ukrainian Black grouse was more pronounced for the neutral variation than for the adaptive one, suggesting that balancing selection is shaping the MHC diversity. Yet, the MHC differentiation between the two studied populations was still high (Dest =0.454), which could be a sign of local adaptations. Thus, it is suggested that the Northern and the Carpathian Black grouse populations should be treated as separate Management Units (MU).Black grouse population in the Carpathian Mountains appeared to be more diverse than the one in the North in terms of neutral and adaptive genetic variation. Therefore, it was suggested that the Carpathian Mountains could have been a refuge for the Black grouse during the last glaciations period. This hypothesis should be tested in the subsequent study involving more extensive sampling in both regions and inferring phylogeographical analysis of Ukrainian Black grouse population.
