In this study, we analyze and compare the genetic structure of edible dormice representing five populations, inhabiting forest complexes in southwestern Poland that differ in their degree of fragmentation and isolation. Total genomic DNA was isolated from hairs with bulbs of 145 individuals captured between 2018 and 2020. All dormice sampled were genotyped at 14 microsatellite loci. Population genetic analyses showed that genetic variability in the studied dormice, assessed based on observed and expected heterozygosity as well as allelic richness, was on average very low (0.39, 0.43, and 2.83, respectively). In the populations studied, genetic structure was detected indicating two or five distinct genetic clusters, the existence of which can be attributed to either historical factors or modern human activity. Genetic differentiation between dormice living in the studied localities, determined by FST, ranged from 0.07 to 0.40 (all FSTcoefficients were significant at P< 0.05). A significant positive correlation was detected between genetic differentiation and geographic distance (r= 0.645, P< 0.017), indicating that genetic differentiation increases with distance, but no correlation between genetic differentiation and habitat barriers (r= 0.359, P< 0.132). The results of this research are compared to those of other European populations of edible dormice, and implications for the future of this endangered species are discussed.We investigated the genetic structure of dormice (Glis glis) representing five populations, inhabiting forest complexes in southwestern Poland that differed in their degree of fragmentation and isolation. The basic parameters of genetic variability in these populations were lower in dormice inhabiting small forest complexes, isolated by cultivated areas. Genetic differentiation between pairs of populations corresponded to the geographic distribution of individual populations, that is, individuals from small isolated populations were clearly genetically different from each other and from dormice from a large contiguous forest complex, indicating limited gene flow between populations. Therefore, it seems that the scenario of a slow, long-term process of loss of genetic diversity due to habitat fragmentation is becoming a real threat to this species.
