| Abstract: | Morphological variation in root vole was studied in 10 samples from the Baikal islands and shore regions. The island samples differed from the continental ones by a set of cranial characters as well as by a higher complexity and asymmetry of morphotypes of the third upper molar. A possible role of biotopic and microclimatic conditions in the formation of a specific morphological pattern of island micropopulations of this species is discussed. |
