| Аннотация: | The role of hybridization in biological evolution and cases of hybridogenic speciation is one of the most complicated but also interesting and actively studied topics. Russet ground squirrel Spermophilus major is known as a fine biological species according to a number of criteria—morphological, ecological, and behavioral, respectively. Nevertheless, a large body of evidence has accumulated on the hybridization of S. major with four neighboring Spermophilus species. Our goal was to identify their contribution to the nuclear and mitochondrial genome of S. major, and to propose a hypothesis describing the hybridization history in space and time. We found that 36% of S. major individuals had extraneous alleles, and every contacting species contributed to S. major’s genetic variability. Our data suggested at least five independent hybridization events that were associated with shifts in the species ranges due to paleoclimate changes. Two of them were potentially accompanied by mitochondrial captures with replacement of the mitochondrial genome of one of the hybridizing species. We highlight the potential threat to the existence of S. major as a species under the current conditions of population decline along with the simultaneous influx of extraneous genes. It is also particularly important to emphasize the necessity of protecting this inhabitant of unique steppe communities. | |
