![]() DUPLICATE DETECTOR FERRET WINDOWS 10 KEYGEN![]() ![]() Generally, polecats are characterized by a remarkable variability in size both between and within sexes (Buchalczyk and Ruprecht 1977). 2003), was bred in captivity as early as the fourth century BC and was introduced to many parts of the world (Nowak and Paradiso 1983). putorius furo), generally thought to be domesticated from M. nigripes exists in a few remaining populations in North America (Matchett 2016). The eastern part of the distribution range of European polecat lies within the range of M. eversmanii is distributed from the southern regions of central and eastern Europe, throughout southern Russia (including southern Siberia) and Middle Asia to Mongolia and northern and western China (Heptner et al. 2018) with an unclear eastern border in the European forest-steppe zone (see Fig. putorius occurs throughout most of Europe from the Great Britain to the Ural Mountains (Croose et al. They form the most clearly defined species group of the genus Mustela (Abramov 2000). eversmanii Lesson, 1827) and the black-footed ferret ( M. Three extant polecat species of the subgenus Putorius are recognized: the European polecat ( Mustela putorius L., 1758), the steppe polecat ( M. We interpret these results as an indication of ongoing hybridisation between sympatric populations, but the low number of hybrids identified suggests limited genetic exchange between the species. putorius populations, only a small fraction of such specimens showed conflict in discrete morphological characters with the diagnostic discriminant function. ![]() Although morphometric analyses revealed several intermediate individuals in size in sympatric M. eversmanii eversmanii was more distant from M. eversmanii, the subspecies and the nominal taxon only partially overlapped, and M. The two species appeared to be clearly differentiated although sympatric populations were closer to each other and had a slight overlap in the morphometric space. Our results revealed a considerable heterogeneity in cranial morphology. We evaluated inter- and intraspecific patterns of morphological differentiation of 20 cranial measurements and four external traits by distance-based morphometric approaches and multivariate analyses. We investigated the morphological relationships in sympatric and allopatric populations of these mustelids with representative sampling, taxonomic and geographic coverage. eversmanii hungarica represents the westernmost part of the latter species and they allegedly hybridize. Both occur sympatrically in the Pannonian Basin, where M. European mustelids include the European polecat, Mustela putorius, and the steppe polecat, M. ![]()
