    Resum:
    For this PhD thesis, Middle and Late Pleistocene populations of M. arvalis and M. agrestis coming from 13 sites of the Iberian Peninsula,14 sites of the Italian Peninsula, nine of the Carpathian Basin, three of Croatia and two of Belgium were analysed from a morphological and morphometric point of view, in order to underlie similarities and differences among them, possible common patterns of evolution and the influence of climatic and environmental conditions on their variations. Comparing samples from different chronologies and different geographic provenance, it was possible to refine the chronological attributions of palaeontological and archaeological sites of the Mediterranean region and to identify divergent lineages, early signs of speciation, immigration events and displacement of populations. Furthermore, we propose the use of a new index, Lagr/Larv, to quantify the variations in size of M. agrestis and M. arvalis in relation to each other. This index proved to be an excellent indicator of the general humidity level and allow to detect oscillations and variations in the environmental conditions in the surroundings of a given sites.
