Serologisheskaya differe siya pyati palearkticheskikh vidov Marmota (Rodentia, Sciuridae) [Distinction sérologique de cinq espèces de marmottes. Serological differentiation of five Palearctic species of Marmota].

Résumé

Serological similarity of five Palearctic species of mamots was determined by immunodiffusion and turbidimentry using the rabbit antiserum agaisnst the blood serum of M. baibacina. The data obtained showed a great antigenic similarity of the serum proteins in the studied species which are, however, at different phylogenetic distances from M. baibacina. M. baibacina and M. bobac are very closedly serologically related. M. caudata and M. menzbieri are more or less equally remote from M. baibacina. M. camtschatica had diverged most of all from M. baibacina in its antigenic structure. These observations concide with the results of chromosome studies indicating that M. camtschatica holds a special place among the Palearctic marmots.
