Внутривидовая дивергенция черношапочного сурка Marmota camtschatica (Sciuridae, Marmotinae). Vnoutrividovaya divergentsiya tchernochapotchnogo sourka Marmota camtschatica (Sciuridae, Marmotinae). [Intraspecific divergence of the black-capped marmot Marmota camtschatica (Sciuridae, Marmotinae). Difference intraspécifique chez la marmotte à tête noire].

Résumé

Morphological and immunogenetic specific features of M. camtschatica were studied. The more significant differences in metric and nonmetric characters of skull were found in Kamchatka and Barguzin subspecies due to their parameters do not overlap. Marmots of Yakutian subspecies occupy an intermediate position between the aforementioned species, but they are also nonuniform. Immunogenetic tests revealed distinct differences between all three M. camtschatica subspecies as well as between two geographical marmot forms from Yakutia. The black-capped marmots appear to belong to species in statu nascendi, whose situation is close to the phenomenon of Rassenkreise ranges of animals. The black-capped marmots are most likely to be considered as a Marmota camtschatica superspecies.
