Genetic diversity and structure of the Black grouse Lyrurus tetrix Linnaeus, 1758 population in Belarus

It is known that black grouse is a valuable resource species of the wild fauna of Belarus. The Belarusian population went through the stages of population decline and redistribution into new agrarian landscape territories – extensive anthropogenic involvement transformed significant parts of the species’ habitat in the course of large-scale land reclamation campaigns, which originated in 1950s. In order to rationally use the preserved black grouse subpopulations, an assessment of the level of their genetic diversity and degree of differentiation was made. For the latter purpose, microsatellite analysis was utilized. It was found that at the present stage the black grouse population has a sufficient level of adaptability (based on indicators of genetic diversity and effective population size) necessary to maintain viability in the foreseeable future.
