“…According to the scaling algorithm, the second direction of variation is associated with interspecific differences in the proportions of characters, rather than in their size (Kovaleva and Faleev, 1994;Kovaleva et al, 1996Kovaleva et al, , 2011Dupal, 2000;Vasil'ev et al, 2004;Dupal and Abramov, 2010). In the era when variation was analyzed by one dimensional methods, an analog to this direction was variation in the relative value of a character, e.g., the ratio of its value to the body length or condylobasal length.…”

The distance joining (DJ) method has been used to combine morphological and molecular genetic (cytb) data on 19 species of Siberian and Far Eastern shrews. It has been found that morphological distances between the species do not correspond to molecular genetic distances (Mantel's test, r = 0.336) due to the size component of morphological variation. Data on the relationships between taxa of generic and spe cies levels according to the molecular marker (cytb) are incongruent to those based on morphometric char acters of the Soricidae, since the cytb gene is a recorder of neutral mutations, whereas the size of morpholog ical characters is a reflection of adaptive evolution. The correlation between the two types of data has notice ably increased (r = 0.799) after the size component was excluded from the morphological distance matrix. The combination of morphological and molecular distance matrices with subsequent nonmetric two dimen sional scaling and dendrogram construction has provided a basis for conclusions about the generic and sub generic structure of the family Soricidae, which basically correspond to current views on the taxonomy of this group, and for hypotheses concerning the taxonomic status of S. mirabilis and S. minutissimus.
