In the review, the known examples of presumable hybrid speciation in mammals are analyzed. It is often not easy to clearly differentiate hybrid speciation and derivatives of other evolutionary scenarios. Nevertheless, the reality of hybrid speciation, both allopolyploid (AHS) and homoploid (HHS), within this class has been demonstrated. Characteristically,(More)
Rodents of the genus Mus represent one of the most valuable biological models for biomedical and evolutionary research. Out of the four currently recognized subgenera, Nannomys (African pygmy mice, including the smallest rodents in the world) comprises the only original African lineage. Species of this subgenus became important models for the study of sex(More)
The results of the body-surface infrared thermography of rodents of the genus Lophuromys suggest that heat insulation of the black-clawed brush-furred rat L. melanonyx, a large specialized species of the AfroAlpine zone, is worse than that of the related smaller species, the golden-footed (L. chrysopus) and shorttailed (L. brevicaudus) brush-furred rats,(More)
The common vole (Microtus arvalis) has been a model species of small mammal for studying end-glacial colonization history. In the present study we expanded the sampling from central and eastern Europe, analyzing contemporary genetic structure to identify the role of a potential 'northern glacial refugium', i.e. a refugium at a higher latitude than the(More)
Although diverse complexes of chromosome races are of rather rare occurrence in mammals, this does not reduce their importance to an insignificant phenomenon unworthy of studying as a unique case without direct analogy. Moreover, these complexes represent virtually ideal models for estimation of the impact of hybridization on the process of microevolution.(More)
