| cranial size and shape variation in isolated populations of the olkhon mountain vole (alticola olchonensis litvinov, 1960). | the olkhon mountain vole (alticola olchonensis) is an endemic species of the lake baikal area with an extremely restricted range. we investigated the pattern of differentiation of cranial shape and size in five isolated insular populations of a. olchonensis from the baikal islands (olkhon, hubyn, borokchin, ogoy, and zamogoy). the ventral aspect of the cranium was analysed using landmark-based geometric morphometric methods while the sexes of a. olchonensis did not differ regarding cranium size ... | 2017 | 28807502 |
