- Аннотация: Variation of anteroconid morphotypes was studied using traditional and GM methods in five volespecies: Stenocranius gregalis, Alexandromys middendorffii, A. mongolicus, A. mujanensis, and A. oeconomus.The morphotypical space is three-dimensional within the framework of the traditional approach, withthe axes being formed by (1) the complexity of the curve of the lingual and (2) labial sides of the AUL, and(3) the overall number of closed triangles. The total number of morphotypes for four species of Alexandromysis 56, with 30 of them being actualized (the degree of completeness of the morphospace is 53.6%). The thinplatespline and Procrustes distance analyses were used in the quantitative approach. The distribution of morphotypesin the space of the first two relative warps (RWs), both for individual species and for their combination,displays an arcuate configuration. The first RW is associated mainly with the complication/simplificationof the buccal side of the anteroconid, while the second RW with the bilateral complication/simplificationand simultaneous extension/compression of the anteroconid. The part of the potential morphospace thatcorresponds to a moderately complicated and maximally elongated anteroconid remains unfilled. The distributionof morphotypes for all species in the space of the first two axes of multidimensional scaling forms asingle and roughly homogeneous cloud that almost evenly fills the total morphospace. The correlation coefficientsbetween the matrices of morphogenetic and Procrustes distances between morphotypes calculatedfor each of the species vary from 0.56 to 0.73.
