In this study, the morphometric variations were investigated in Farmland and Hillside populations of subterranean rodent Nannospalax xanthodon from Central Anatolia. A total of 31 parameters were measured in the skull and mandible of 35 male individuals. Multivariate analysis (MVA) of the obtained cranial data was used to determine the parameters that varied between habitats and chromosomal populations (2n = 54 and 2n = 60). Furthermore, the effect of soil hardness on the morphology of the dorsal skull of male and female individuals was investigated. As a result, habitat differences caused some morphometric variations in the skull dorsal, especially facial bones, whereas the samples with diploid chromosome number 2n = 54 and 2n = 60 were separated by eight cranial parametric measurements. Accordingly, the known effect of ecological factors on phylogenetic variations in digging animals has first discussed in Nannospalax xantodon cytotypes.
