Variation of morphological parameters in isolated populations of Alticola olchonensis (Rodentia, Arvicolidae) from islands of lake baikal

摘要

Variation of morphological parameters of skull in isolated Alticola olchonensis polulations from Baikal islands was investigated using the univariate statistics, principal components and canonical discriminant analyses. Each island polulation has its own specific morphologica features. The influence of historical and ecogeographical factors on the adaptive variation of isolated Alticola olchonensis polulations is discussed.
