摘要: Seventeen extant populations of Microtus (Terricola) savii have been investigated for correlations first lower molar shape to climatic variables by means geometric morphometrics, and controlling phylogenetic inheritance. Comparative methods revealed that phylogeography provide a very similar contribution variation in molars morphology, whereas tooth size does not appear be affected conditions. Climate-related changes recognized the anteroconid portion tooth. This indicates is strongly influenced conditions, although complex way. Calabrian populations, often ascribed brachycercus, form distinct cluster, agreement with most recent genetic analyses.
