The Spatial-Genetic Population Structure of Eptesicus nibsonii (Chiroptera, Vespertilionidae) on the Southern Border of Its Range within European Russia

摘要

The spatial and genetic structure of theEptesicus nilssoniipopulation was studied. The species is characterized by conservatism of wintering sites. The key territories in the gene flow between colonies are swarming sites. After wintering, most individuals fly to a distance not exceeding 15 km, which is confirmed by the positive values of genetic isolation distance (p = 0.05). Females are characterized by natal philopatry, whereas males are characterized by natal dispersal. High genetic diversity and moderate genetic differentiation were found in wintering areas and summer habitat areas. Most intrapopulation groups are heterogeneous, but some show deviations from the Hardy-Weinberg equilibrium (p 0.05), and inbreeding is possible.
