Skull Features Of The Common Vole (Microtus Arvalis Sensu Lato) From Hungary: Craniometrical Evidence For Its Taxonomic Detachment, Georgi Markov, Gabor Csorba, Maria Kocheva, Milena Gospodinova
Turkish Journal of Zoology
A revision was carried out on 245 adult skull specimens of the common vole (Microtus arvalis sensu lato) kept in the mammal collection of the Hungarian Natural History Museum in Budapest. A highly effective craniometric classification function was used to reveal whether they belonged to the common vole (M. arvalis Pallas, 1778 sensu stricto) or to the East European vole (Microtus levis Miller, 1908). It was found that M. levis specimens were present in the Hungarian mammal fauna; the boundaries of that animal's European range were thus expanded in the west. The distribution of the East European vole and the …
