The estimation of the cranial variety of the rodents in conditions of the Central Caucasus in order to development the base of the quality environment monitoring

The analysis of morphological cranium variety in the rodents (Mus musculus and Apodemus uralensis) of the Central Caucasus (the northern macroslope) using Shannon entropy is made. The differences in the skull structure of the synanthropic and wild rodents are revealed, A. uralensis is more adapted to the current ecological and geographic environmental factors, thus representing to a large extent in the skull organization.
