This note describes and comments on some cases of common voles Microtus arvalis (Pallas, 1778) characterised by a first lower molar with a pitymyan rhombus.
New insight into the colonization processes of common voles: inferences from molecular and fossil evidence.

Biologie et Gestion des Populations, Campus International de Baillarguet, Montferrier/Lez, FranceElucidating the colonization processes associated with Quaternary climatic cycles is important in order to understand the distribution of biodiversity and the evolutionary potential of temperate plant and animal species. In Europe, general evolutionary scenarios have been defined from genetic evidence. Recently, these scenarios have been challenged with genetic as well as fossil data. The origins of the modern distributions of most temperate plant and animal species could predate the Last Glacial Maximum. The glacial survival of such populations may have occurred in either southern (Mediterranea…

An analysis of the diversity in the dentition of the common vole, Microtus arvalis, from three localities near Częstochowa (Panki, Przystajń and Mstów) is provided. Populations from these areas were compared to each other in these terms. The teeth were analyzed – the first lower molar (M1) and the upper third molar of the maxilla (M3). Four basic forms of Simplex, Typica, Duplicata and Variabilis were used to study the diversity of the upper tooth. We developed our own model for studying the differentiation of the lower tooth. The present research and a comparison with literature data confirm that the subspecies M. a. duplicatus does occur in the study area.
